    Full Text Available Lipomatous lesions are common musculoskeletal lesions that can arise within the soft tissues, bone, neurovascular structures, and synovium. The majority of these lesions are benign, and many of the benign lesions can be diagnosed by radiologic evaluation. However, radiologic differences between benign and malignant lipomatous lesions may be subtle and pathologic correlation is often needed. The use of sonography, computed tomography (CT, and magnetic resonance imaging (MRI is useful not only in portraying fat within the lesion, but also for evaluating the presence and extent of soft tissue components. Lipomas make up most soft tissue lipomatous lesions, but careful evaluation must be performed to distinguish these lesions from a low-grade liposarcoma. In addition to the imaging appearance, the location of the lesion and the patient demographics can be utilized to help diagnose other soft tissue lipomatous lesions, such as elastofibroma dorsi, angiolipoma, lipoblastoma, and hibernoma. Osseous lipomatous lesions such as a parosteal lipoma and intraosseous lipoma occur less commonly as their soft tissue counterpart, but are also benign. Neurovascular and synovial lipomatous lesions are much rarer lesions but demonstrate more classic radiologic findings, particularly on MRI. A review of the clinical, radiologic, and pathologic characteristics of these lesions is presented.

    Lipomas of the neck are uncommon lesions. Those situated in deep locations and diffuse lipomatosis of the neck can be clinically mis diagnosed. We reviewed the 20 lipomatous neck lesions treated in our hospital over a 15-year period (1985-1999). Computed tomography was diagnostic in nearly 100% of cases and, this, is the method of choice for the detection and characterization of lipomatous tumors. It also provides data that aid in planning the surgical approach and enables the follow-up of clinically stable lesions that do not require surgical treatment. (Author) 11 refs

    Full text: A hibernoma is a rare benign soft tissue tumor derived from brown fat. The tumor is also known as 'fetal' lipoma, lipoma of embriogenic fat and lipoma of immature adipose tissue. Hibernomas are slow growing, painless soft tissue tumors which do not recur after surgical resection. Preferred locations are brown fat containing sites as thigh, inter scapular region, shoulder, axilla and mediastinum. The tumor occurs most commonly in adults, with a mean age of 38 years (age range, 2-75 years). We present a rare case of hibernoma with radiological and pathological findings

    2004-01-01

    Purpose: To assess the value of fine-needle aspiration cytology in the diagnostic work-up of lipomatous tumors of the extremities and trunk, and to identify specific radiological features that could aid in the preoperative evaluation. Material and Methods: 175 patients with subfascial lipomatous tumors who had undergone preoperative magnetic resonance imaging or computed tomography and fine-needle aspiration cytology were studied. The percentage of fat within the lesion was visually graded from the images as: none, 1-75%, 75-95%, or 95-100%. The histological and cytological diagnoses were compared and in discordant cases the radiological images were re-reviewed. Results: There was cytological and histological concordance in 96% of lipomas and in 85% of atypical lipomatous tumors (ALT) and liposarcomas. Most discordant cases exhibited 1-75% fat. Radiological review suggested that cytological sampling problems due to tumor heterogeneity were the main cause of diagnostic difficulties. The majority of tumors with less than 75% fat were liposarcomas, and in no liposarcoma was the fat content higher than 75%. Both ALT and lipoma were found in the 95-100% group. Conclusion: Cytology can be highly accurate in the diagnosis of lipomatous tumors, including ALT; however, critical comparison with the radiological findings increases diagnostic security. In tumors with fat content visually assessed as less than 75% of the tumor volume, liposarcoma is the most likely diagnosis and a cytological diagnosis of ALT or lipoma should be questioned. In lesions with 75-95% fat, liposarcoma is unlikely, but FNAC is still indicated for safety. In lesions with 95-100% fat, FNAC is only indicated if the differentiation between lipoma and ALT influences the treatment strategy

    Lipomatous hemangiopericytoma (LHPC) is recently recognized as a rare hemangiopericytoma variant. To our knowledge, imaging features of LHPC involving skull base have not yet been reported. We present the imaging features of LHPC of skull base in a 44-year-old female, along with a literature review CT and magnetic resonance imagings showed well-enhanced fatty issues containing temporal skull base masses, with pressure bony erosions.

  8. 110 Subfascial lipomatous tumors. MR and CT findings versus histopathological diagnosis and cytogenetic analysis

    Einarsdottir, H.; Soederlund, V.; Larsson, O.; Mandahl, N.; Bauer, H.C.F.

    1999-01-01

    Purpose: To evaluate whether liposarcoma, atypical lipomatous tumors and lipoma can be differentiated radiologically. Material and Methods: We have retrospectively analyzed CT and/or MR images of 110 subfascial lipomatous lesions. The amount of fat within the tumors was visually graded from the images as: none, 1-75%, 75-95% or 95-100%. The structure of non-fatty tumor components was compared. The images were compared to histopathology and in 37 cases to cytogenetic findings. Results: Only 4 of 20 liposarcomas contained fat. All 4 lesions, histopathologically diagnosed as atypical lipomatous tumors, contained fat but less than 75% of tumor volume. All lesions with more fat than 75% of tumor volume were histologically diagnosed as lipomas. However, one-third of the karyotyped lipomas had ring chromosomes which are considered typical for atypical lipomatous tumors. Conclusion: When a tumor is composed more or less solely of fat, the diagnosis of a lipoma or atypical lipomatous tumor with a phenotype simulating a lipoma can be assumed. When the fat content is less than 75% of the tumor volume or non-fatty nodules are found, biopsies from different tumor components have to be performed to exclude malignancy. When no fat is found, imaging does not help in differentiating lipoma or liposarcoma from other soft tissue tumors. (orig.)

    Full Text Available Adult intussusception is rare unlike childhood variety where it is the leading cause of intestinal obstruction. Preoperative diagnosis is often difficult as the symptoms are nonspecific and so high index of suspicion is needed for early diagnosis by appropriate investigations. This is a case of 65-year-old man presented with acute intestinal obstruction whose laparotomy revealed a jejunojejunal intussusception secondary to a lipomatous lesion which was successfully treated with resection and primary anastomosis. When dealing with a case of chronic intermittent intestinal obstruction, intussusception must be kept in mind as one of the differential diagnosis.

    Full Text Available Lipomatous angiomyofibroblastoma (LAMF is a rare superficial muco-cutaneous tumor of the female genital tract in women of reproductive age and early menopause. We report the case of a 36-year-old woman who presented with an asymptomatic 1 cm round vulvar mass. The tumor showed both hypercellular and hypocellular areas composed of spindle and epithelioid cells set in a loose fibromyxoid background. Anastomosing networks of small to medium sized dilated vessels, surrounded by condensed spindle cells, were distributed equally throughout the tumor. Mature adipocytes comprised more than half of the tumor's volume. The neoplastic cells were reactive for both desmin and vimentin and did not express CD34, smooth muscle actin, S100 protein and muscle-specific actin. Making the right diagnosis may be challenging to medical professionals as LAMF may mimic both clinically and histologically several other benign and malignant gynecological lesions. LAMF has a benign course without evidence of local recurrence or metastatic potential.

    Full Text Available Cameron syndrome is the ulcerative or erosive lesions of mucosal layer at the sac of hiatal hernia which can cause chronic occult or overt bleeding and iron-deficiency anemia. Hiatal hernia is a relatively frequent finding, which is in most cases asymptomatic or manifested by dyspeptic symptoms of varying severity. Despite of being a very important association of hiatal hernia Cameron syndrome is not widely represented in medical literature. That`s the reason of a lack of awareness among physicians, surgeons and endoscopists about that pathology. Cameron lesions are significant pathology because they can become a source of chronic occult as well as an acute life-threatening bleeding. Those lesions of upper gastrointestinal tract are often misinterpreted or overlooked during standard diagnostic procedures. It can lead to the misdiagnosis and false ways of treatment. The review focuses on the pathogenesis, main diagnostic problems and treatment options of that pathology. The diagnostics of the Cameron syndrome is difficult because sometimes the lesions can`t be seen on upper gastrointestinal tract endoscopy. The review describes the criteria by which the physician may suspect Cameron syndrome when endoscopy results are not certain. Clinical case represents an important problem which is often faced by the doctors — the severe iron-deficiency anemia refractory to the medication and blood transfusions in the patients with Cameron lesions. It`s very important for doctor to be aware of that complication to include Cameron syndrome into the diagnostic search for the sources of persistent blood loss. Cameron lesions can be asymptomatic as well as be manifested in the form of severe chronic anemia. And that`s the reason why there are an important issue about the proper treatment which have to be provided in each case. The review describes the effectiveness of different treatment options and makes the conclusion about the principles on which doctor can

    In this study, the detection of MDM2 and CDK4 amplification was evaluated in lipomatous soft tissue tumors using multiplex ligation-dependent probe amplification (MLPA), a PCR-based technique, in comparison with fluorescence in situ hybridization (FISH). These 2 techniques were evaluated in a series of 77 formalin-fixed, paraffin-embedded lipomatous tumors (27 benign adipose tumors, 28 atypical lipomatous tumors/well-differentiated liposarcomas, 18 dedifferentiated liposarcomas, and 4 pleomorphic liposarcomas). Using MLPA, with a cut-off ratio of >2, 36/71 samples (22 atypical lipomatous tumors/well-differentiated liposarcomas, and 14 dedifferentiated liposarcomas) showed MDM2 and CDK4 amplification. Using FISH as gold standard, MLPA showed a sensitivity of 90% (36/40) and a specificity of 100% (31/31) in detecting amplification of MDM2 and CDK4 in lipomatous soft tissue tumors. In case of high-level amplification (MDM2-CDK4/CEP12 ratio >5), concordance was 100%. Four cases of atypical lipomatous tumor/well-differentiated liposarcoma (4/26, 15%) with a low MDM2 and CDK4 amplification level (MDM2-CDK4/CEP12 ratio ranging between 2 and 2.5) detected by FISH showed no amplification by MLPA, although gain of MDM2 and CDK4 (ratios ranging between 1.6 and 1.9) was seen with MLPA. No amplification was detected in benign lipomatous tumors and pleomorphic liposarcomas. Furthermore, there was a very high concordance between the ratios obtained by FISH and MLPA. In conclusion, MLPA proves to be an appropriate and straightforward technique for screening MDM2/CDK4 amplification in lipomatous tumors, especially when a correct cut-off value and reference samples are chosen, and could be considered a good alternative to FISH to determine MDM2 and CDK4 amplification in liposarcomas. Moreover, because MLPA, as a multiplex technique, allows simultaneous detection of multiple chromosomal changes of interest, it could be in the future a very reliable and fast molecular analysis on

    The case is presented of a 51 year-old woman with a firm mass at the medial canthus of the right eye of five years onset. A low-grade lymphoproliferative lesion (reactive lymphoid hyperplasia) was diagnosed from an excisional biopsy Lacrimal sac tumors are rare, with a peak incidence in the fifth decade of life. The initial clinical features are epiphora and medial canthus swelling. As it mimics nasolacrimal duct obstruction, up to 40% of these tumors are misdiagnosed until undergoing surgery.

    Two hundred and three MR examinations were reviewed of 195 patients with lipomatous, fibrous and muscular tissues tumors which were evaluated at staging or during the follow-up. All examinations were obtained with a 1.5 T superconductive magnet, and both T 1 and T 2 -weighted images were acquired. Its high contrast resolution, its direct multiplanarity and its allowing both T 1 and T 2 -weighted images to be obtained are the mos important characteristics of MR imaging. In our experience, MRI demonstrated a high overall accuracy (94.8%) - 94.1% at restaging alone - with similar sensitivity both at the staging of the disease (97.5%) and during the follow-up (96%). Overall sensibility was 96.3%. MR specificity in histologically proven relapses was 86.8%. Even though it is gradually assessing itself as the most important method in the evaluation of soft tissues masses, MRI allows an histological diagnosis to be made only in lipomatous tumors and in benign fibrous tumors due to their specific signal features. The commonest though specific finding is a soft tissue mass with relatively low signal intensity in T 1 -weighted images. In our opinion, MR imaging is the method of choice during the follow-up of the disease, whereas it is probably a complementary technique in the staging. (author)

    Full Text Available OBJECTIVE: To demonstrate the main aspects of diagnosis, treatment and follow-up of 43 patients with gunshot wounds to the penis. MATERIALS AND METHODS: The location of the lesion, the presence of associated lesions, the performance of complementary exams, surgical treatment, postoperative complications and long term follow-up of 43 patients with penile lesions from gunshot wounds were retrospectively analyzed. RESULTS: Of 43 cases assessed, 41 were submitted to surgical exploration (95.3% and 2 were submitted to conservative treatment (4.7%. We found penile lesions involving the corpus cavernosum in 37 cases; the remaining 4 patients presented no lesions involving the corpus cavernosum, urethra or testicles but did in the superficial structures. Ten cases presented an association with testicular lesions and 14 cases association with anterior urethral lesions. CONCLUSION: Penile lesions from gunshot wounds should be treated with immediate surgical intervention. In exceptional situations featuring superficial lesions only conservative treatment may be applied.

    Full text: Primary hyperparathyroidism can course with bone lesions known as fibrocystic osteitis in 25% to 60% of the cases and manifest itself by fractures, bone pain, deformations and inflammatory reaction. A 17 years old patient was listened with report of trauma in the left wrist, lumbar and in the right knee pain, with inflammatory signals and thinning 15 kg in 8 months. After x-ray of the left wrist and hand, bone rarefaction and insufflated lesion in the left chiro-dactyl third proximal phalanx were observed. The laboratory examinations have demonstrated hyper calcemia (13mg/dl), hypo phosphatemia (1,3mg/dl) with alkaline phosphatase (1086UI/I) e PTH (1050ng/ml). X-ray of the cranium cap, hip and coxofemoral articulations, knees and ankle was realized and observed disseminated lithic lesions. The bone scintilography with Technetium-99m MDP revealed hypo and hyper uptaked regions in several segments of the appendicular axial skeleton. Because of primary hyperparathyroidism suspicion, parathyroid scintilography with Technetium-99m MIBI in two phases was realized. 30 min after the injection of the radiopharmaceutical whole body images were realized which demonstrated hyper absorption in the areas previously hypo to the bone scintilography. 3 hours after injection the uptake was maintained in projection of the left inferior parathyroid, with posterior adenoma resection. The patient presented a significant reduction of the bone pain and normalization of the serum calcium levels. Nuclear medicine had an important role in the investigation of parathyroid diseases and showed to be useful in the evaluation of the disseminated bone compromising, which can come along with this pathology, avoiding the realization of repeated radiological studies

    Full Text Available Radiolucent mandibular lesions are commonly evident on head and neck imaging and present a diagnostic dilemma for the radiologist. These may represent a broad spectrum of lesions arising from both odontogenic and nonodontogenic structures. Furthermore, few radiolucent lesions are often identified as incidental lesions by the radiologist on imaging performed for different reasons. Location of the lesion, borders, internal structure, and its effect on surrounding structures are the key points to narrow the differential diagnosis. Imaging is essential not only for the diagnosis of lesions, but also to guide therapy and monitor the treatment response. Here is a case report on traumatic bone cyst that presented as an asymptomatic radiolucent lesion in right posterior mandible and was discovered incidentally on routine radiograph. The lesion was diagnosed based on patient′s anamnesis and radiographic examination. This paper aims at discussing the differential diagnosis, various radiological characteristics, and their prediction in prognosis of the lesion.

    Full Text Available Petrous apex lesions of temporal bone progress slowly. Most of the time not only destruct this area but also involve neighbouring element. The symptoms of the neighbouring neuro-vasculare involvement we can recognize these lesions. The most common symptoms of involvement of the petrous apex are: headache, conductive hearing loss or sensorineural type, paresthesia and anesthesia of the trigeminal nerve, paresia and paralysis of the facial nerve, abducent nerve. In retrospective study which has been in the ENT and HNS wards of Amiralam hospital, 148 patients have been operated due to temporal bone tumor; from these numbers, 21 (13.6% patients had petrous apex lesions of temporal bone. Eleven (52.9% patients of these 21 persons were men and the remaining 10 (47-6% were women. The average age of the patients was 37 years. The common pathology of these patients were glomus jugulare tumors, hemangioma, schwannoma, meningioma, congenital cholesteatoma, giant cell granuloma. The kind of operations that have been done on these patients were: infratemporal, translabyrinthine and middle fossa approaches. The conclusion of this study shows that petrous apex area is an occult site. The symptoms of this lesion are not characteristic, meticulous attention to the history and physical examination are very helpful to recognition of these lesions and it's extention.

    To investigate clinical and pathological features of lung lesions in children. Clinical manifestations, radiologic imaging, histopathological features and immunohistochemical results were analyzed in 215 cases of lung lesions in children. A total of 215 cases of lung lesions in children aged 0 day to 13 years (average age of 27.2 months and the median age of 18.0 months) were selected, including 137 male and 78 female patients with a male to female ratio of 1.76:1.00. The incidence of congenital lung disease was higher in patients of less than 1 year old than those of over 1 year old age, and the difference of the two groups was statistically significant (P = 0.004). 142 cases had acquired lung diseases, and 73 cases had congenital bronchopulmonary dysplasia. Lung abscess was the most common lesion seen in 86 cases (40.0%), including 1 case of fungal abscess. Congenital pulmonary airway malformation (CPAM) was the second most common, seen in 44 patients (20.5%), including 20 cases of type 1, 18 cases of type 2 and 6 cases of type 4 CPAM. Pulmonary sequestration was found in 25 cases (11.6%) including 14 cases of intralobar type and 11 cases of extralobar type. Two cases of extralobar pulmonary sequestration showed simultaneous CPAM2 type 2 lesion. Other lesions included tuberculosis (13 cases, 6.0%), emphysema (12 cases, 5.6%), interstitial pneumonia (7 cases, 3.2%), pulmonary hemorrhage (6 cases, 2.8%), bronchogenic cyst (4 cases, 1.9%), bronchiolitis obliterans (2 cases, 0.9%), idiopathic pulmonary hemosiderin deposition disease (2 cases, 0.9%) and 1 cases of lung non-specific changes. 13 cases of neoplastic lesions (6.0%) were found, of which 11 cases were primary tumors (5.1%), including inflammatory myofibroblastic tumor in 5 patients (2.3%), pleuropulmonary blastoma in 5 cases (1 case of type I, 2 type II and 2 type III) and 1 case of mucoepidermoid carcinoma (0.5%) and 2 cases of metastatic tumors (hepatoblastoma and Wilm's tumor, 0.9%).

    2015-03-01

    Full Text Available The presence of lytic lesions in the bones of foot raises a number of diagnostic possibilities ranging from infection, inflammatory pathology to neoplastic conditions. Although the radiological picture is not pathognomonic of any pathology, clinical history and histopathological examination can help to clinch the diagnosis. We present a case of multiple lytic lesions of the foot and discuss possible differential diagnoses. The patient was diagnosed as a case of madura foot and the lesions responded to surgical debridement and anti-fungal treatment with a good functional outcome. Madura foot is an uncommon, chronic granulomatous fungal or bacterial infection with a predilection in people who walk barefoot. Although known for a specific geographical distribution, madura foot should be kept as a possible diagnosis in patients presenting with lytic lesions of the foot due to population emigration across the world.

    To determine the frequency and types of skin lesions in cases of dengue fever in patients admitted in three hospitals of Karachi. Case series. Three tertiary care hospitals of Karachi, from November 2006 to February 2007. One hundred patients of dengue fever with positive anti-dengue Immunoglobulin M (IgM) serology were included in the study. The admitted patients in PNS Shifa Hospital, Jinnah Postgraduate Medical Centre (JPMC) and Civil Hospital, Karachi were selected for the study. Presenting features were noted. The patients were physically examined for the presence of skin and mucosal lesions and findings were recorded. Total and Differential Leukocyte Count (TLC and DLC), platelet count and Liver Function Tests (LFTs) were done in all the patients. All the patients had low leukocyte and low platelet counts. The common presenting symptoms were high-grade fever with or without rigors, headache, body aches, backache, vomiting, sore throat with cough and generalized weakness (seen in 86% patients). The uncommon presenting features were diarrhea, abdominal pain, bleeding from gums and nosebleeds (seen in 14% patients). Sixty-eight (68%) patients had skin lesions. The most common skin presentation was generalized macular blanchable erythema involving trunk and limbs, seen in 44 (65%) cases. Discrete petechial lesions were seen on various body areas in 24 (35%) cases. Palmer erythema was seen in 20 (30%) patients. Generalized itching was seen in 16 (23%) cases. Isolated itching of palms and soles was seen in 20 (30%) cases. Twenty-eight (28%) patients had deranged LFTs. Out of those, 4 patients had raised serum bilirubin level whereas rest of the 24 had raised ALT. Dengue fever commonly presents with specific skin lesions. The skin lesions can be a clue to the diagnosis in difficult cases.

    To determine the frequency and types of skin lesions in cases of dengue fever in patients admitted in three hospitals of Karachi. One hundred patients of dengue fever with positive anti-dengue Immunoglobulin M (IgM) serology were included in the study. The admitted patients in PNS Shifa Hospital, Jinnah Postgraduate Medical Centre (JPMC) and Civil Hospital, Karachi were selected for the study. Presenting features were noted. The patients were physically examined for the presence of skin and mucosal lesions and findings were recorded. Total and Differential Leukocyte Count (TLC and DLC), platelet count and Liver Function Tests (LFTs) were done in all the patients. All the patients had low leukocyte and low platelet counts. The common presenting symptoms were high-grade fever with or without rigors, headache, body aches, backache, vomiting, sore throat with cough and generalized weakness (seen in 86% patients). The uncommon presenting features were diarrhea, abdominal pain, bleeding from gums and nosebleeds (seen in 14% patients). Sixty-eight (68%) patients had skin lesions. The most common skin presentation was generalized macular blanchable erythema involving trunk and limbs, seen in 44 (65%) cases. Discrete petechial lesions were seen on various body areas in 24 (35%) cases. Palmer erythema was seen in 20 (30%) patients. Generalized itching was seen in 16 (23%) cases.

    Full Text Available Host modulation, includes inhibition of matrix metalloproteinases, blocking production of proinflammatory cytokines and inhibition of osteoclastic activity, has therapeutic value as adjunctive therapy in treating chronic periodontitis. This case series presented three patients with chief complaint of teeth mobility where endo perio involvement was diagnosed. The endo perio combined lesions generally shows the communication between pulp and periodontal tissues with the same origin of dental infection. Diagnosis in such cases is difficult and generally raising problem in the management. All of the cases were managed by non surgical endodontic therapy combined with host modulation. All local factors causing the lesion were removed. Clinical outcome after six and nine months were quite satisfactory. Combined endo perio cases are challenging to the dentists and involve multidisciplinary involvement. To manage such cases, dentists have to rely on the unconventional techniques.DOI: 10.14693/jdi.v22i1.378

    Transient splenial lesions (TSL) of the corpus callosum are uncommon radiologic findings that are seen in a number of clinical conditions with varied etiologies. They were first described a decade earlier in patients with epilepsy and hence were thought to be seizure or seizure therapy related. Subsequently, more cases were described by different observers in diseases with different etiologies, and the list is still increasing. Awareness of these lesions is necessary as they are an uncommon finding and have to be differentiated from other infective/noninfective causes. MRI is the imaging modality of choice as these lesions are not seen on routine noncontrast CT scan. The authors here describe two cases which showed TSL, with complete/partial resolution on follow-up scans. The authors also present a review of the literature

    A radicular cyst associated with carious teeth is a very common odontogenic lesion in the oral cavity, but calcifications in residual radicular cysts are quite rare. We report one such case where a routine pre-implant radiographic assessment revealed a mixed periapical radiopaque radiolucent lesion in the right maxillary central incisor region. Histological and radiographic studies show that there is a slow increase in the mineralized deposits within the cyst lumen with time. This becomes prominent histochemically in cysts more than 8 years old and radiographically 6 years later, as seen in our case. In this paper we would like to highlight the importance of a residual radicular cyst with calcifications in the differential diagnosis of a mixed periapical radiopaque radiolucent lesion.

    The study was carried out in 70 cases of carcinoma cervix uteri, showing varying degree of proctitis following radiotherapy treatment for cervical cancer. Grossly, the rectal mucosa showed oedema, congestion, granular proctitis, ulceration, and microscopically stromal connective tissue as well as epithelial changes. The stromal changes have been emphasised as useful diagnostic criteria of radiation reaction. The familarity of these changes is considered necessary because it is imperative to know categorically that a given lesion is entirely or in part due to radiation or due to extension of adjacent tumour in the cervix. Further, this issue is very important in management of cases of cancer cervix. The criteria of distinguishing the lesions in the rectal tissue have been laid down. (auth.)

    Full Text Available INTRODUCTION Benign Lesions of Larynx (BLL have been defined as “An abnormal mass of tissue in larynx, the growth of which exceeds and is coordinated with that of normal tissue and persists in the same excessive manner after cessation of stimuli which evoked the change.” These lesions have significant influence on vocal, social and emotional adjustments of patients. These patients present with hoarseness of voice. AIM A clinical study was undertaken at Govt. ENT Hospital, Hyderabad, for 1 year from January 2014 to December 2014. Aim of this study was to analyze age and sex distribution, symptomatology, sites of involvement, management and recurrence of benign lesions of larynx. MATERIAL AND METHODS A total of 50 patients were studied who were admitted in the hospital. Inclusion criteria: Patients with Hoarseness of Voice (HOV /change of voice, difficulty in breathing and swallowing, vocal fatigue, Foreign Body (FB sensation in the throat. Exclusion criteria: Malignancy of larynx and acute inflammatory conditions of larynx. RESULTS Benign lesions of larynx show male preponderance with M:F ratio of 2.12:1, with common age group between 31 to 40 years. Chronic vocal misuse was the predominant cause and more in professional voice users. The common lesion was Vocal Cord (VC polyp, followed by VC nodules and papillomas. Common side involved was right side. Majority of the patients had to undergo surgery. Majority of recurrence was seen in laryngeal papillomas (33.33%. CONCLUSION Benign lesions of larynx produce symptoms which vary from mild HOV to life threatening stridor. Early diagnosis leads to effective management. Males were more affected and maximum cases seen between 31 to 40 years. Chronic voice abuse, smoking, alcohol, frequent throat clearing and Laryngopharyngeal Reflux (LPR/Gastroesophageal Reflux Disease (GERD are precipitating factors. Microlaryngeal Surgery (MLS, voice rest and speech therapy offer a cost effective, useful and safe

    Many cases of patients with neuromyelitis optica have submitted without demyelinating lesions in the cerebral white matter, it has documented that this entity can cause from the onset of illness or through its natural evolution. Diagnostic methods currently as Magnetic Resonance Imaging (MRI) and specific antibodies in plasma (such as antiaquaporin-4) have been diagnosed of neuromyelitis optica cases that were initially confused with multiple sclerosis. Disease in Costa Rica has been little prevalent and is not exactly known what the prevalence and incidence. The degree of disorder is illustrated through a case study, both in the cerebral white matter as spinal cord, in a patient with neuromyelitis optica during a follow-up period of 4 years. This is the first case that has been reported in the scientific literature of Costa Rica. (author) [es

    Lipofibromatosis is a rare, benign, but infiltrative, soft tissue tumor seen in children. We present three cases of lipofibromatosis, each with different magnetic resonance imaging features and correlate this with the histological findings. The patients comprised two males and one female who presented in infancy; at birth, 5 months, and 7 months of age. Clinically, the masses were painless and slow-growing. The masses ranged in size from 2 to 6 cm and involved the distal extremities in two cases (one foot, one wrist) and the trunk. Magnetic resonance imaging showed lipomatous lesions with varying amounts of adipose and solid components in each case. There were no capsules at the periphery of the lesions. One case showed a fat-predominant lesion, another an equal mixture of fat and solid tissue, and the third was predominantly solid. This was reflected in the histology, which showed corresponding features. Radiological and histopathological differential diagnoses are reviewed. (orig.)

    Full Text Available An 18-year-old youth soccer forward received a direct hit from a kicked soccer ball on the anterior right chest when the goal keeper kicked the ball from a distance of 1 meter. Immediately following the hit, the subject experienced dypnea, chest pain and had a cough, with several milliliters of hemoptysis. His symptoms subsided after 20 minutes of rest. However, he still felt mild discomfort and was taken to our department for evaluation. On examination, all vital signs were normal. A computed tomography scan of the chest was obtained, and revealed a small area of opacification in the right lung field suggesting a pulmonary contusion or traumatic lung edema. Ten days after the initial injury, he was cleared for full participation. We herein reported the first case of a lung lesion induced by a soccer ball. Conservative treatment resulted in a favorable outcome.

    Morel-Lavallee lesions are closed degloving soft tissue injuries which occur because of trauma and in which the skin and subcutaneous tissue are separated from superficial fascia. This shear trauma results in creation of a potential space filled with serosanguinous fluid, blood and necrotic fat. We discuss a case of 52-year-old female with history of trauma one week back, who presented with a boggy swelling over the postero-lateral aspect of proximal forearm and distal arm. Local examination showed fluctuating fluid collection. MRI showed variable intensity fluid collection in a potential space between the subcutaneous tissue and deep fascia in arm and forearm. Percutaneous decompression and evacuation of the collection with systemic antibiotic therapy resulted in rapid improvement.

  8. Fine needle aspiration cytology of pseudosarcomatous reactive lesions of soft tissues: A report of two cases

    Directory of Open Access Journals (Sweden)

    Suchitha Satish

    2012-01-01

    Full Text Available Pseudosarcomatous lesions are reactive proliferative lesions of the soft tissue, that are likely to be misdiagnosed as malignant, based on clinical and histological features. The most common lesions are nodular fasciitis, proliferative fasciitis, proliferative myositis and myositis ossificans. These rapidly growing soft-tissue lesions can represent a variety of diagnoses involving radically different treatment modalities. Accurate diagnosis is important to avoid unnecessary and often mutilating surgery. We report two cases to illustrate the importance of correct identification of these lesions by fine needle aspiration cytology.

    Reports of post-traumatic cyst-like lesions in children are rare. These lesions occur between 1.5 and 3 months after a fracture. They are more frequent after a distal radius greenstick fracture. Conventional radiographs show a metaphyseal radiolucent lesion inside the most recent subperiosteal bone, adjacent to the initial fracture line. Post-traumatic cyst-like lesions are benign, asymptomatic, nonexpansive, and regress spontaneously. Two typical cases are described in the following report with a literature review of the etiology and main features of these lesions.

    Teeth with periapical lesions can undergo successful orthodontic treatment, but conventional protocols indicate that such teeth should be endodontically stabilized prior to such treatment. A case report is presented where such endodontic stabilization was not possible, yet a chronic periapical lesion resolved as orthodontic treatment progressed. This paper will discuss the possible causes of the initial lesion, and reasons why it resolved without endodontic treatment. This report illustrates the possible combined roles of trauma, occlusion and periodontal disease in the development of a perio-endo lesion, and how orthodontic treatment potentially relieved some of the exacerbating factors, thus enabling resolution of the infection without endodontic treatment.

    White, non scrapable lesions are commonly seen in the oral cavity. Based on their history and clinical appearance, most of these lesions can be easily diagnosed, but sometimes diagnosis may go wrong. In order to arrive to a confirmative diagnosis, histopathological assessment is needed in many cases, if not all. 1) To find out the prevalence of clinically diagnosed oral white, non scrapable lesions. 2) To find out the prevalence of histopathologically diagnosed oral white, non scrapable lesions. 3) To correlate the clinical and histopathological diagnosis in the above lesions. A total of 100 cases of oral white, non scrapable lesions were included in the study. Based on their history and clinical presentation, clinical provisional diagnosis was made. Then biopsy was done and confirmatory histopathological diagnosis was given and both were correlated. In order to correlate clinical and histopathological diagnosis Discrepancy Index (DI) was calculated for all the cases. Based on clinical diagnosis, there were 59 cases (59%) of leukoplakia, 29 cases (29%) of lichen planus and six cases (6%) of lichenoid reaction; whereas, based on histopathological diagnosis, there were 66 cases (66%) of leukoplakia epithelial hyperplasia and hyperkeratosis (leukoplakia) and 30 cases (30%) of lichen planus. Seventy eight clinically diagnosed cases (78%) correlated with the histopathological diagnosis and 22 cases (22%) did not correlate. The total discrepancy index was 22%. A clinician needs to be aware of oral white, non scrapable lesions. Due to the overlapping of many clinical features in some of these lesions and also due to their malignant potential, a histopathological confirmative diagnosis is recommended.

    Cerebral sparganosis, a parasitic disease, rarely produces a chronic active inflammatory response in the brain. Clinically and radiographically the process may mimic a neoplasm. We report a 30-year-old man who underwent surgical exploration for a mass in the insular cortex. Histology revealed a densely fibrotic mass heavily infiltrated with plasma cells and lymphocytes, in which were embedded parasitic forms consistent with sparganosis. We describe the MRI appearances and pathologic features. Intracranial mass lesions secondary to sparganosis must be considered in patients with a history of travel to endemic areas, especially Asia.

    Dieulafoy's lesion is one of an unusual cause of upper gastrointestinal bleeding (U GIB). Endoscopic intervention has always been a preferred non-surgical method in treating UGIB including bleeding from Dieulafoy's lesion. Owing to recent advances in angiography, arterial embolization has become a popular alternative in non- variceal UGIB especially in cases with failed endoscopic treatment. However, managing bleeding Dieulafoy's with selective arterial embolization as the first line of treatment has not been exclusively practiced. We hereby, report a case of bleeding Dieulafoy lesion which had been primarily treated with arterial embolization.

    Full Text Available The infection of the root canal system is considered to be a polymicrobial infection, consisting of both aerobic and anaerobic bacteria. Because of the complexity of the root canal infection, it is unlikely that any single antibiotic could result in effective sterilization of the canal. A combination of antibiotic drugs (metronidazole, ciprofloxacin, and minocycline is used to eliminate target bacteria, which are possible sources of endodontic lesions. Three case reports describe the nonsurgical endodontic treatment of teeth with large periradicular lesions. A triple antibiotic paste was used for 3 months. After 3 months, teeth were asymptomatic and were obturated. The follow-up radiograph of all the three cases showed progressive healing of periradicular lesions. The results of these cases show that when most commonly used medicaments fail in eliminating the symptoms then a triple antibiotic paste can be used clinically in the treatment of teeth with large periradicular lesions.

    Many cases of patients with neuromyelitis optica have submitted without demyelinating lesions in the cerebral white matter, it has documented that this entity can cause from the onset of illness or through its natural evolution. Diagnostic methods currently as Magnetic Resonance Imaging (MRI) and specific antibodies in plasma (such as antiaquaporin-4) have been diagnosed of neuromyelitis optica cases that were initially confused with multiple sclerosis. Disease in Costa Rica has been little prevalent and is not exactly known what the prevalence and incidence. The degree of disorder is illustrated through a case study, both in the cerebral white matter as spinal cord, in a patient with neuromyelitis optica during a follow-up period of 4 years. This is the first case that has been reported in the scientific literature of Costa Rica.

    The purpose of this article is to describe a case of multiple giant cell lesions of the mandible that occurred in a 14-year-old girl with phenotypic characteristics associated with Noonan Syndrome (NS). NS is a dysmorphic disorder characterized by hypertelorism, short stature, congenital heart defects, short and webbed neck, skeletal anomalies, and bleeding diathesis. A 14-year-old girl with a previous diagnosis of NS (sporadic case) presented with multiple radiolucent lesions in the body and ramus of her mandible. In terms of clinical behavior and the described radiographic characteristics, giant cells lesions with Noonan-like phenotype can be considered a form of cherubism. Therefore, surgical intervention is not necessary, but radiographic follow-up and observation is very important during the control and gradual regression of the lesions.

    Pulpal and periodontal problems are responsible for more than half of the tooth mortality. There are some articles published in the literature about this issue. Many of them are quite old. There has been also lack of knowledge about the effect of endodontic treatment on the periodontal tissue healing and suitable treatment interval between endodontic and periodontal treatments. In this case report, different kinds of endo-perio lesion were treated with sequential endodontic and periodontal treatment. The follow-up radiographs showed complete healing of the hard and soft tissue lesions. The tooth with endo-perio lesions should be evaluated thoroughly in terms of any cracks and fracture, especially furcation areas for a long term prognosis. In this case report, it was showed that 3 months treatment intervals between endodontic treatment and periodontal surgery has no harmful effect on periodontal tissue healing. Key words:Endo-perio lesion, furcation, mandibular molar, bone graft, crack line, treatment interval.

    Full Text Available Melorheostosis is a rare, nonhereditary, benign, mesenchymal condition of unknown aetiology affecting the bones and surrounding tissues. A male patient complaining of left shoulder pain, swelling, and mildly limited range of motion has an exclusive combination of the classic dripping wax lesion in the scapula and the myositis ossificans-like lesion in the deltoid muscle; this combination is the first to be reported in the shoulder. Both lesions showed typical findings of melorheostosis in radiographs, CT, MRI, and bone scan. This case has a stationary course over the follow-up period, and no specific treatment is needed in due course.

    Full Text Available We present the case of a 45 year old female patient with an incidental diagnosis of a cystic pancreatic lesion corresponding to a serous cystadenoma of 14 mm. During a 5-year follow-up (CT and MRT the lesion tripled in size and a surgical intervention was decided upon. The lesion was thought to have a benign pathology and, in an attempt to preserve the spleen and a major portion of pancreatic tissue, a central pancreatectomy with a diversion of the remaining distal pancreas was carried out. The authors reviewed national and international publications.

    The Morel-Lavallee lesion is a closed, internal degloving injury that results when a strong, shearing force is applied parallel to the plane of injury, as is common in vehicular trauma. It is an underdiagnosed entity that is often missed during the initial trauma workup as symptoms can be subtle. There are few reports of lesions occurring below the knee. Most cases affect the proximal thigh and trochanter, as these tend to be dependent areas in high velocity trauma. To the best of our knowledge, this is the first literature report of bilateral lower extremity Morel-Lavallee lesions.

    Uremic encephalopathy (UE) is a well-known complication of uremia, but its pathophysiology remains unknown. It is widely reported that in UE, the bilateral basal ganglia (BG) shows hyperintensities on T2/fluid attenuated inversion recovery magnetic resonance imaging (MRI), but cerebellar lesions are extremely rare, with to the best of our knowledge, only one case reported to date. We describe the findings from computed tomography and MRI for typical BG and cerebellar vermis lesions.

    The first histologically confirmed case of a classic chordoma arising in a precursor benign notochordal lesion is presented and the differential diagnosis between benign and malignant notochordal lesions is discussed. A 57-year-old man presented with a classic chordoma in the coccyx. The resected specimen demonstrated a small intraosseous benign notochordal lesion in the coccyx, which was adjacent to the classic chordoma. Also seen were two separate, similar benign lesions in the sacrum. The classic chordoma consisted of multiple lobules that were separated by thin fibrous septa and that showed cords or strands of atypical physaliphorous cells set within an abundant myxoid matrix. In contrast, the benign lesions consisted of intraosseous sheets of bland physaliphorous cells without any extracellular matrix. The affected bone trabeculae showed sclerotic reactions. It was concluded that benign and malignant notochordal lesions can be distinguished microscopically. (orig.)

    Periapical lesions develop as sequelae to pulp disease. Periapical radiolucent areas are generally diagnosed either during routine dental radiographic examination or following acute toothache. Various methods can be used in the nonsurgical management of periapical lesions: the conservative root canal treatment, decompression technique, active nonsurgical decompression technique, aspiration-irrigation technique, method using calcium hydroxide, lesion sterilization and repair therapy and the apexum procedure. Monitoring the healing of periapical lesions is essential through periodic follow-up examinations. The ultimate goal of endodontic therapy should be to return the involved teeth to a state of health and function without surgical intervention. All inflammatory periapical lesions should be initially treated with conservative nonsurgical procedures. Surgical intervention is recommended only after nonsurgical techniques have failed. Besides, surgery has many drawbacks, which limit its use in the management of periapical lesions. How to cite this article: Sood N, Maheshwari N, Gothi R, Sood N.

    Full Text Available Odontogenic keratocyst is a cyst of dental lamina origin with a high recurrence rate and well defined histologic criteria. Radiographically, odontogenic keratocyst presents as a unilocular or multilocular radiolucency of the jaws. Its capacity for aggressive growth and recurrence even after many years makes it an entity of special interest. Recently, neoplastic transformations have also been reported. They must therefore be distinguished from other cysts and tumors of the jaws. We report a case of fortuitous bilobular radiolucency in the left ascending ramus of a patient, who reported with a clinical presentation of submandibular space cellulitis.

    The mechanisms and functional anatomy underlying the early stages of speech perception are still not well understood. Auditory agnosia is a deficit of auditory object processing defined as a disability to recognize spoken languages and/or nonverbal environmental sounds and music despite adequate hearing while spontaneous speech, reading and writing are preserved. Usually, either the bilateral or unilateral temporal lobe, especially the transverse gyral lesions, are responsible for auditory agnosia. Subcortical lesions without cortical damage rarely causes auditory agnosia. We present a 73-year-old right-handed male with generalized auditory agnosia caused by a unilateral subcortical lesion. He was not able to repeat or dictate but to perform fluent and comprehensible speech. He could understand and read written words and phrases. His auditory brainstem evoked potential and audiometry were intact. This case suggested that the subcortical lesion involving unilateral acoustic radiation could cause generalized auditory agnosia.

    We report a rare case of a metastatic sphenoid sinus lesion originating from an undiagnosed hepatocellular carcinoma (HCC) in a 53-year-old man who presented with gradually progressive external ophthalmoplegia. Imaging showed a right sphenoid sinus lesion infiltrating the parasellar region. Although a primary sphenoid biopsy was inconclusive, positive hepatitis B surface antigen and CT-guided fine-needle aspiration cytology suggested an HCC. A repeat endoscopic biopsy from the sphenoid with immunohistochemistry confirmed the lesion to be metastatic HCC. Metastasis to the paranasal sinuses is extremely rare, and metastasis from a liver primary even more rare. Because of clinical and radiologic similarity between the primary and metastatic lesions, metastasis to the sphenoid sinus is often undiagnosed. Patients with features suggestive of sphenoid sinus malignancy should also be evaluated for the possibility of a metastatic tumor. In this article, we emphasize the rarity of the tumor, the unusual presenting symptoms, and problems with early diagnosis.

    Breast masses occur in men far less commonly than women and are infrequently subjected to fine-needle aspiration (FNA) biopsy. Papillary lesions of the male breast are rare and are comprised of a spectrum of lesions ranging from papillary hyperplasia in gynecomastia to invasive papillary carcinoma. The following study describes the cytomorphology of papillary breast lesions in 11 men. The patients ranged in age from 23 to 78 years old and each presented with an unilateral subareolar or periareolar breast mass that varied in size from 0.5 to 3 cm. Two patients presented with bloody nipple discharge. Archival material (8-year period) from FNA biopsies of papillary lesions of the male breast was reviewed. The reviewed cases were correlated with appropriate clinicopathologic follow-up. The smears had variable cellularity but all showed papillary clusters of mammary epithelial cells with and without fibrovascular cores. Single epithelial cells with a high nuclear-to-cytoplasmic ratio and eccentric nuclei were seen in all smears; however, these were more numerous in cases of adenocarcinoma. Hemosiderin-laden macrophages were present in all cases. Nipple discharge was seen only in the 2 benign lesions. All adenocarcinomas occurred in older men. The only cytologic criteria that differentiated benign from malignant papillary lesions were marked cellularity and the presence of abundant 3-dimensional clusters. To the best of the authors' knowledge, the current series is the largest in the English literature to date that examines the cytomorphologic features of papillary breast lesions in men.

    Full Text Available Abstract Introduction Prostate cancer is the second most common cancer in men and the fifth most common cancer worldwide. In the USA it is more common in African-American men than in Caucasian men. Prostate cancer frequently metastasizes to bone and the lesions appear osteoblastic on radiographs. Presentation with diffuse osteolytic bone lesions is rare. We describe an unusual presentation of metastatic prostate cancer with diffuse osteolytic bone lesions. Case presentation A 65-year-old Namibian man presented with anemia, thrombocytopenia and worsening back pains. In addition he had complaints of effort intolerance, palpitations, dysuria and mild symptoms of bladder outlet obstruction. On examination he was found to be anemic, had a swollen tender right shoulder joint and spine tenderness to percussion. On digital rectal examination he had asymmetrical enlargement of the prostate which felt nodular and hard with diffuse firmness in some parts. His prostate-specific antigen was greater than 100ng/mL and he had diffuse osteolytic lesions involving the right humerus, and all vertebral, femur and pelvic bones. His screen for multiple myeloma was negative and the prostate biopsy confirmed prostate cancer. Conclusion Prostate cancer rarely presents with diffuse osteolytic bone lesions and should be considered in the differential diagnosis when evaluating male patients with osteolytic bone lesions.

    Full Text Available Objective  To summarize the clinical and MRI imaging features, treatment and prognosis of reversible splenial lesion syndrome (RESLES. Methods  The clinical manifestation and MRI imaging appearances of 13 RESLES patients were retrospectively evaluated and the pertinent literatures of RESLES were reviewed. Results  Of the 13 cases (11 males and 2 female, aged from 13 to 58 years, 1 was complicated with spontaneous intracranial hypotension syndrome, 1 with epidemic hemorrhagic fever, 1 with antiepileptic drug withdraw, 1 with pituitary crisis combining Sjogren syndrome, 1 with still disease, and 8 cases were complicated with viral encephalitis (meningoencephalitis. The first MRI imaging was performed from 2 to 39 days after onset. All the lesions were measured about 1-2cm, located in the central area and involved no other part of corpus callosum. They were characterized by high signal intensity on FLAIR and T2 sequences, with mild signal reduction on T1 sequence, and hyperintensity on DWI with low apparent diffusion coefficient (ADC values. The lesions formed as ovoid and boomerang. Following intravenous injection of contrast medium in 3 cases, no enhancement was found in the splenial lesions. All the patients completely recovered or obviously improved after appropriate treatments. The splenial lesions disappeared or obviously weakened on the follow-up MRI imaging, ranging from 6 to 30 days after first MRI imaging. Conclusions  RESLES is characterized by the MRI finding as a reversible lesion with transiently reduced diffusion in the splenium of corpus callosum. Symptoms of RESLES are various, the outcome is favorable in most cases, and the etiology and pathogenesis of RESLES are still unclear. DOI: 10.11855/j.issn.0577-7402.2016.10.09

    Fibroblastic connective tissue nevus (FCTN) represents a rare and distinct benign cutaneous mesenchymal lesion of fibroblastic/myofibroblastic lineage, which broadens the spectrum of lesions presently recognized as connective tissue nevus. A series of 25 cases of FCTN has been analyzed to further characterize the clinicopathologic spectrum and immunohistochemical features of this entity. Sixteen patients were female (64%) and 9 were male (36%), with age at presentation ranging from 1.5 months to 58 years (median, 10 y). Most patients presented with a solitary, slowly growing, painless plaque-like or nodular skin lesion. Eleven cases (44%) arose on the trunk, 9 (36%) on the head and neck, and 5 (20%) on the limbs. The lesion was present for a median duration of 11.5 months (mean, 13.2 mo). Grossly, the lesions were tan-brown to tan-white, smooth, and firm. Their size ranged from 0.3 to 2.0 cm in greatest dimension (mean size, 0.67 cm; median, 0.6 cm). All tumors showed poor circumscription and were situated primarily in the reticular deep dermis, extending into the superficial subcutis in 13 cases (52%). The lesion was associated with papillomatous epidermis in 17 cases (70%) and the presence of adipose tissue in the reticular dermis in 14 cases (60.9%). All tumors were composed of a proliferation of bland intradermal fibroblastic/myofibroblastic cells with indistinct palely eosinophilic cytoplasm and tapering nuclei, with no significant cytologic atypia or pleomorphism, arranged in short-intersecting fascicles and entrapping appendages. No mitoses were identified. Immunostains showed positivity for CD34 in 20 of 23 cases (87%) and weak focal positivity for smooth muscle actin in 9 of 19 cases (47%). No case stained positively for desmin or S100 protein. Clinical follow-up was obtained for 14 patients (median duration, 4 y). No tumor recurred locally, even when surgical excision was incomplete. No lesion metastasized. FCTN occurs most commonly as a plaque on the

    2016-01-01

    Lesions of nonendodontic origin, such as nasopalatine or globulomaxillary cysts, may mimic periapical radiolucencies associated with pulpal pathosis, and incorrect diagnosis may lead to unnecessary endodontic treatment. Horizontal root fractures most commonly affect the maxillary central and lateral incisors. Prognosis depends largely on the level of fracture; fractures in the apical third have the best prognosis, and those in the cervical third have the worst. This case report discusses surgical and restorative management of a patient who had a nasopalatine cyst that had been misdiagnosed and treated as an endodontic lesion of the maxillary right central incisor as well as a midroot horizontal fracture of the adjacent lateral incisor.

    Full Text Available Dental traumatic injuries may affect the teeth and alveolar bone directly or indirectly. Pulpal necrosis and chronic and apical periodontitis with cystic changes are the most common sequelae of the dental traumatic injuries, if the teeth are not treated immediately. This case report focuses on the conventional and surgical management of mandibular central incisors. A twenty-four-year-old male patient presented with pain in the mandibular central incisors. Radiographic examination revealed mandibular central incisors with dumbbell shaped periapical lesion. After root canal treatment, parendodontic surgery was performed for mandibular central incisors. After one-year recall examination, the teeth were asymptomatic and periapical lesion had healed.

    2008-01-01

    Full Text Available Background: Fine needle aspiration cytology (FNAC of the thyroid gland has been widely and successfully utilized for diagnosis. Aim: Our aim was to demonstrate the effectiveness of this cheap and simple procedure for the diagnosis of different thyroid lesions, particularly, differentiation of malignant and nonmalignant lesions. In addition, we sought to highlight probable causes of error and possible remedies in the cases showing lack of correlation between cytological and histological diagnoses. Materials and Methods: A total of 288 cases of thyroid swellings were aspirated in our two-year study period. Cases were divided into four groups, namely, aspiration inadequate where diagnosis was not offered; a nonneoplastic group which included different goiters and thyroiditis; an indeterminate group which included cases showing features of follicular or Hurthle cell neoplasms, and a malignant group that included nonfollicular malignant tumors of the thyroid. Cases showing cytohistologic disparity were reevaluated. Results: Almost 14% of the cases could not be reported because of inadequate aspiration, however, an overall cytohistological correlation was achieved in 82.66% of all cases. Sensitivity and specificity for the diagnosis of malignancy were 92.7 and 98.2%, respectively. There were four false negative malignant cases with one false positive case and 13 cases failed to show any cytohistological correlation. Conclusions: FNAC is the single most important test for preoperative assessment of thyroid pathology if attention is paid to the clinical features and collection of samples from proper sites.

    Background: Periapical lesions (PLs) occur as a result of pulpal inflammation and may rarely be seen in the absence of pulpal diseases. They are the most common pathological lesions affecting the alveolar bone. Objective: This study aims to describe the clinicopathological features of PLs of the jaws with emphasis on the two most common types. Methods: Histopathology records of PLs diagnosed from January 1990 to December 2012 at the Department of Oral Pathology, University College Hospital Ibadan, were examined and categorized into periapical cysts (PCs); periapical granuloma (PGs) and others. Clinical data and histopathological features of these PLs were reviewed and analyzed. Results: One hundred and four lesions met the criteria for this study and consisted of PGs with 71 (68.3%) cases and PCs with 31 (29.8%) cases and one case each of apical scar and pleomorphic adenoma. Age range of cases was 9 to 80 years (mean=35.6 ± 15.8years) with a peak at age group of 20-29 years. Females were more frequently affected with 51.9% of cases. PLs were most frequently diagnosed in the anterior maxillary region with 58 (56.9%) cases, while the most frequently involved tooth was the left maxillary central incisor with 23 (22.1%) cases. Conclusion: Findings in this study are consistent with those of previous studies. It is important for all periapical pathological specimens to be submitted for histological examination to establish an accurate diagnosis and aid in the identification of sinister lesions that may present in the Periradicular region of teeth.

    A 50-year-old male presented with complaints of fatigue, confusion, and memory problems. Neurological evaluation revealed altered cognition, unsteady gait, ataxia, dysmetria, and weakness. MRI of the brain was initially unremarkable. Over several days, the patient experienced improvement of symptoms and a follow-up MRI revealed a small lesion in the splenium of the corpus callosum seen on diffusion weighted and T2 sequences. The patient was discovered to have elevated anti-voltage gated potassium channel serum autoantibodies. Follow-up MRI revealed resolution of the splenial lesion. The patient was treated with intravenous immune globulin, and improved back to his pre-treatment baseline. We believe this to be the first case of a reversible splenial lesion syndrome as a manifestation of the anti-voltage gated potassium channel autoantibody syndrome, and propose a pathophysiologic mechanism.

    Inflammatory cysts, granulomas, abscesses, and fibrous scars represent most periapical radiolucencies. However, other less common lesions, such as orthokeratinized odontogenic cysts (OOCs), can be found at this region, and they deserve to be discussed because the prognosis for an OOC is different from that expected for the ordinary inflammatory periapical diseases. An interesting case of OOC associated with a nonvital tooth in a 40-year-old woman is described. After a previous clinical diagnosis of a radicular cyst, the tooth was extracted, and the lesion was enucleated and submitted to microscopy examination. Because of the detection of an orthokeratinized epithelium lining, a diagnosis of OOC was concluded. After 2 years of periodic follow-up, no signs of recurrence were detected. The presence of keratin in radicular lesions must be carefully evaluated to eliminate the diagnosis of lesions with more aggressive behavior, such as an OOC or even a keratocystic odontogenic tumor. Hence, histopathologic examination is mandatory to confirm the type of lesion and to differentiate other pathologic conditions, therefore establishing patients' prognoses precisely.

    Radiologic images obtained in nine patients with known primary cancer and occipital or head and neck pain were retrospectively reviewed after having been initially interpreted as normal. Imaging studies included head computed tomography (CT) in five cases, brain magnetic resonance (MR) imaging in six cases, cervical spine CT and MR imaging in five cases, radiography in two cases, and scintigraphy in two cases. This reevaluation demonstrated lesions of the occipital condyles in all patients. Seven patients had unilateral occipital condyle masses, and two patients had bilateral condyle lesions. Lesions were found to either involve only the occipital condyle (n = 4), extend to the adjacent occipital bone (n = 3), or extend to the ipsilateral clivus (n = 2). Misinterpretation of radiologic examinations resulted in an average delay in diagnosis of 10 weeks from the onset of symptoms to definitive therapy (irradiation). It is important to evaluate the occipital condyles in all patients with occipital pain, especially those with cancer. Neoplastic disease involving the occipital condyles is not common; however, it is frequently missed at imaging. Careful review of unenhanced sagittal and axial T1-weighted MR images and of the inferior sections from axial head CT studies will make it possible to avoid this potential pitfall.

    Full Text Available Lichenoid reactions represent a family of lesions with different etiologic factors and a common clinical and histologic appearance. Lichen planus is included with lichenoid reactions and is a relatively common chronic mucocutaneous disorder. The most important complication of lichenoid reactions is the possibility of malignant transformation. That is why it has been considered a precancerous condition. Although the malignant transformation rate varies widely in the literature, from 0.4 to 6.5 percent, in most studies it does not exceed 1%. The aim of this paper is to report a rare case of squamous cell carcinoma (SCC arising within an oral lichenoid lesion in a 17-year-old woman, where SCC is very uncommon. The patient did not have any risk factors and was healthy. The lesion was located on the border of the tongue. In view of the common occurrence of OLP (oral lichen planus and the unresolved issues regarding its premalignant potential, this case report illustrates the need for histologic confirmation and a close follow-up of clinical lesions with lichenoid features.

    Congenital cystic lung lesions are rare. Mainly affects the lower respiratory patishta.i are congenital cystic malformation and adematozna bronchopulmonary sequestration (BPS). The pathogenesis of the occurrence of these malformations is not clear but they have a common clinical course. In most cases, the anomaly is asymptomatic and occurs with infections of the lung during the first year of life. Currently congenital lung lesions were classified into five types and is considered by most authors. The anomaly is due to the abnormal proliferation of terminal bronchioles accompanied by inhibition of alveolar development between 7-17 weeks, obstructed airway dysplasia and metaplasia of normal lung tissue. Early diagnosis is vital in making a medical decision on how to treat CCAM. Associated with abnormalities of the urinary tract, cardiovascular system, gastrointestinal atresia, diaphragmatic hernia skeletal abnormalities. In pregnancies in which prenatal lung lesions weighs registered necessary series of ultrasound examinations to track finding and using the Doppler to assess how the blood supply of the fault. The clinical presentation of malformations is respiratory distress, respiratory infection, and dyspnea. The use of CT and MRA allows better visualization of the pulmonary lesions. With its combination with arteriography and bronchoscopy are used to differentiate CCAM and pulmonary sequestration. We present three cases with lung lesions were born in Neonatologia clinic at the University Hospital of Obstetrics and Gynecology "Maternity" Sofia for the period 2010-2012 three cases CCAMs type 1, operated by 5 meters after birth with a good final outcome without complications in the postoperative period and lack of pulmonary symptoms up to 1 year after birth.

    To determine the distribution and clinical outcome of ocular lesions in snakes. Retrospective case series. 67 snakes with ocular lesions. Signalment, lesion duration, diagnosis, treatment, and clinical outcome were recorded for all snakes with ocular lesions that were examined at a veterinary teaching hospital from 1985 to 2010. 71 ocular lesions were detected in 67 of 508 (13%) snakes examined. Affected snakes were of the families Boidae, Pythonidae, Colubridae, and Viperidae. The distribution of ocular lesions did not vary by taxonomic family, age, or sex; however, snakes from the genus Epicrates with ocular lesions were overrepresented in the population. The most commonly diagnosed ocular lesions were retained spectacle (n = 41), pseudobuphthalmos or subspectacular abscess (13), trauma (8), and cataracts (4). Pseudobuphthalmos or subspectacular abscess developed more frequently in Colubridae than in non-Colubridae snakes. Of the 16 snakes with retained spectacles for which data were available, the lesion recurred once in 4 snakes and multiple times in 5 snakes. Results indicated that retained spectacle was the most common ocular lesion diagnosed in snakes. Compared with other snakes with ocular lesions, snakes of the genus Epicrates had a higher than expected frequency of ocular lesions in general and snakes of the family Colubridae had a higher than expected frequency of pseudobuphthalmos or subspectacular abscess.

    Diagnosis of Wallenberg's syndrome has been made by typical neurological symptoms and signs which are compatible with those of lesion in the lateral aspect of medulla oblongata. Although X-ray CT is an extraordinary useful measure for detecting lesions in the central nervous system, brainstem lesion is difficult to be evaluated by it because of varieties of artifact. A recent advance in techniques of magnetic resonance imaging (MRI) made it possible to produce fairly good images of infratentorial structure without artifact. But, there are no reports on patients with Wallenberg's syndrome whose lesion was clearly delineated by MRI. A 44 year-old man with a history of hypertension was referred to our hospital because of vertigo, pain on the right side of the face, disturbance of swallowing and hiccup 22 days after onset. On admission, neurological examination revealed right Horner's sign, decreased gag reflex and cerebellar ataxia on the right side, and dissociated sensory impairment on the right side of the face and left extremities. Clinical diagnosis of Wallenberg's syndrome was made, but X-ray CT showed no definite lesion in the infratentorial structure. Cerebral angiography revealed occlusion of the right vertebral artery without reflux of contrast media from the left vertebral artery. Then, there was no visualization of the right posterior inferior cerebellar artery. MRI using Magnetom (0.35 Tesla of static magnetic field produced by superconducting magnet) clearly delineated low intensity area in the right lateral aspect of the medulla oblongata. This is the first case of Wallenberg's syndrome whose anatomical lesion was demonstrated by MRI. (author)

    A 26-year-old right-handed woman, with a history of left temporal lobe contusion caused by a fall at the age of 9 months, started to have complex partial seizures with oral automatism at the age of 7 years. The seizures occurred once or twice a month despite combination therapy with several antiepileptic agents. Her history and imaging studies suggested the diagnosis of epilepsy arising from traumatic neocortical temporal lesion. Comprehensive assessment including long-term video EEG monitoring, MRI, FDG-PET, MEG, and neuropsychological evaluation was performed at the age of 26 years. The diagnosis was left mesial temporal lobe epilepsy associated with hippocampal atrophy and traumatic temporal cortical lesion. The patient was readmitted for surgical treatment at the age of 27 years. Intracranial EEG monitoring showed that ictal discharges started in the left hippocampus and spread to the traumatic lesion in the left posterior superior temporal gyrus 10 seconds after the onset. This case could not be classified as dual pathology exactly, because the traumatic left temporal cortical lesion did not show independent epileptogenicity. However, the traumatic lesion was highly likely to be the source of the epileptogenicity, and she had right hemispheric dominance for language and functional deterioration in the whole temporal cortex. Therefore, left amygdalo-hippocampectomy and left temporal lobectomy including the traumatic lesion were performed according to the diagnosis of dual pathology. Subsequently, she remained seizure-free for 3 years. Comprehensive assessment of seizure semiology, neurophysiology, neuroradiology, and neuropsychology is important to determine the optimum therapeutic strategies for drug-resistant epilepsy.

    A fictitious patient, Mr. Challenge, is admitted to the emergency room and displays symptoms consistent with damage to the central nervous system. In this problem-based learning case, students are challenged to determine the location of a lesion that is consistent with Mr. Challenge's symptoms. Students discover details about Mr. Challenge's symptoms while exploring three anatomical pathways: corticospinal tract, spinothalamic tract and medial lemniscal pathway. Students make predictions as to which of these pathways may be damaged in Mr. Challenge and defend their predictions based on their research of the function and anatomical location of these tracts. This ultimately leads the student to identifying a single lesion site that can account for Mr. Challenge's symptoms. This case is executed in an undergraduate neuroscience course and would be useful in anatomy and physiology course, as well as other courses that serve students interested in health science related careers.

    Full Text Available Plasma cell granuloma (PCG is a rare reactive tumor such as proliferation composed chiefly of plasmacytic infiltrate. Both clinically and histopathologically, it may be misinterpreted as various pathological entities thus necessitating the complete evaluation of patient and proper histopathological and immunohistochemical analysis of the tissue to rule out other lesions with poor prognosis. Here, we present a case of PCG of gingiva in a female patient masquerading as pyogenic granuloma clinically and plasma cell neoplasms histopathologically.

    1983-01-01

    Hemiballism of the right limbs developed after cerebral infarction in an 83-year-old female patient. On admission, examination revealed hemiballism of the right limbs, monologia, disorientation of thought and motor skills, irritability and the absence of DTR in the right upper limb. Without aggressive treatment, however, involuntary movement disappeared after 18 days, and she was discharged on her own power. CT scan demonstrated a low density area in the left fronto-parietal lobe. However, no obvious abnormality in bilateral subthalamic nuclei was observed. Although the contralateral subthalamic body of Luys is involved in most instances, lesions have been reported to exist in the cerebral cortex, thalamus, corpus striatum, internal capsule and brain stem in some cases. The prognosis for this disease has been generally considered to be fatal. However, this case demonstrated an atypical lesion in CT scan, and spontaneous recovery from hemiballism took place within three weeks. Previous reports on hemiballism were reviewed, and responsive lesions and the prognosis for this case were discussed. (author)

  2. Invasive Mucinous Adenocarcinoma Associated with Adjacent Sessile Serrated Lesion of the Appendix Vermiform: A Case Report

    Directory of Open Access Journals (Sweden)

    Osamu Kinoshita

    2014-01-01

    Full Text Available Although the definition of sessile serrated lesion (SSL of colon is controversial and the risk of progression to malignancy is also under investigation at present, SSL is generally described as a polyp characterized by a serrated architecture. It is estimated to represent a feature of a new cancerization pathway, coined “serrated neoplasia pathway,” particularly in right-sided colon adenocarcinomas. On the other hand, in appendix, the role of this pathway remains uncertain, probably because very few cases of appendiceal adenocarcinoma associated with SSL were reported, and furthermore, immunohistochemical examination was rarely carried out. We herein report an interesting case of invasive appendiceal mucinous adenocarcinoma exhibiting SSL, which was pathologically estimated as a potential precursor lesion, and performed representative immunohistochemistry for both the mucinous adenocarcinoma and SSL in the same specimen. To further elucidate the progression of the appendiceal carcinoma from SSL, both an adequate sectioning of the lesion and systematic immunohistochemical examination of a large number of appendiceal carcinoma cases containing adjacent SSL would be required.

    Full Text Available Background: Tumors of the central nervous system in the pediatric age group occur relatively frequently during the early years of life. Brain tumors are the most common solid malignancies of childhood and only second to acute childhood leukemia. Squash cytology is an indispensable diagnostic aid to central nervous system (CNS lesions. The definitive diagnosis of brain lesions is confirmed by histological examination. Aim: To study the cytology of CNS lesions in pediatric population and correlate it with histopathology. Materials and Methods: One hundred and fifty cases of CNS lesions in pediatric patients were studied over a period of 2 years. Intraoperative squash smears were prepared, stained with hematoxylin and eosin, and examined. Remaining sample was subjected to histopathological examination. Results: Medulloblastoma (24.0% was the most frequently encountered tumor followed by pilocyctic astrocytoma (21.33% and ependymoma (13.33%. Diagnostic accuracy of squash smear technique was 94.67% when compared with histological diagnosis. Conclusion: Smear cytology is a fairly accurate tool for intraoperative CNS consultations.

    Gamma Knife has become a major therapeutic method for intracranial meningiomas, vascular malformations and schwannomas with exact effect. In recent years an increasing number of delayed complications after Gamma Knife surgery have been reported, such as secondary tumors, cystic changes or cyst formation. But angiomatous lesion and delayed cyst formation after Gamma Knife for intracranial lesion has rarely been reported. Here we report the first case of angiomatous lesion and delayed cyst formation following Gamma Knife for intracranial meningioma and discuss its pathogenesis.

    The aim of this case report is to histologically evaluate periapical healing after combined endodontic-periodontic treatment. A maxillary left central incisor was treated with conventional endodontic therapy, followed by periodontal surgery. The facial bony defect was filled with a mixture of autologous bone and Bio-Oss. A resorbable membrane was used. Histology showed the presence of new cementum, ligament, and bone around the apex of the treated tooth. This finding was clinically associated with minimal residual probing depth and maximum attachment gain. This histologic report demonstrates the possibility of true regeneration in a case of severe periodontal attachment loss resulting from an endodontic-periodontic lesion.

  7. Syphilis: an atypical case of sepsis and multiple anogenital lesions in secondary syphilis

    2016-10-01

    Full Text Available The incidence of syphilis has historically been cyclical in nature, often in relation to the rise and fall of public health initiatives directed toward eradication along with social attitudes toward sexual practices. The incidence of syphilis has increased by 15% in the last 6 years in the United States, with similar increases worldwide. Herein, we present an atypical case of syphilis presenting with severe septic shock and multiple anogenital lesions in an immunocompetent host. A 22-year-old male with no significant past medical history presented with fevers, chills, sore throat, diaphoresis, and diarrhea. He was febrile, tachycardic, hypotensive, and unresponsive to fluid resuscitation requiring short-term vasopressor support. Physical exam revealed diffuse lymphadenopathy; lower extremity macular rash involving the soles of the feet; papular non-pustular lesions on the scrotum; and a 0.5 cm non-tender irregular, healing lesion on the shaft of the penis. Laboratory analysis was significant for leukocytosis and elevated creatinine. Serum screening rapid plasma reagin was positive, and further testing revealed a titer of 1:32, with confirmation via fluorescent treponemal antibody absorption test. The patient was diagnosed with secondary syphilis, which was determined to be the underlying etiology of the sepsis as all other serological evaluations were negative. He was treated with penicillin G benzathine 2.4 million units intramuscular and supportive management, with improvement of symptoms. The patient engaged in high-risk sexual behaviors, including prior unprotected sexual contact with males. New research indicates that up to one-third of patients may present with atypical cutaneous manifestations, as demonstrated by this patient. It is important for physicians to familiarize themselves with the varied clinical presentations of syphilis, which include multiple anogenital lesions and tender primary lesions in primary or secondary syphilis.

    2017-10-01

    Full Text Available In this case report, the management of a concomitant endodontic-periodontal lesion case is described. A 31-year-old patient presented with symptomatic apical periodontitis of tooth #36 due to failed endodontic treatment and a generalized aggressive periodontitis. Following full-mouth scaling and root-planing, a root-canal retreatment (tooth #36 was initiated. While the distal and mesio-buccal canals were successfully treated, a transportation perforation of the mesio-lingual canal occurred and was repaired by the MTA. An apical microsurgery of the mesial root combined with surgical periodontal debridement for the lower left quadrant was performed. Three weeks later, resective and regenerative periodontal surgeries of the other 3 quadrants were accomplished. Because of the 6-month post-operative healing, the regenerative periodontal surgery for the lower-left quadrant was performed. The 6-month post-operative recall showed complete healing of the mesial root lesion and reduction of the distal root lesion. The multidisciplinary approach and advanced armamentarium contributed to favourable outcome.

    Arthroscopic reconstruction of the anterior cruciate ligament (ACL) using autografts or allografts is a common surgical procedure, particularly in young athletes. Although the procedure has excellent success rates, complications such as mechanical impingement, graft rupture, and arthrofibrosis can occur, often necessitating additional surgery. Magnetic resonance (MR) imaging has become a valuable tool in evaluating complications after ACL reconstruction. We report two cases of ACL reconstruction complicated by arthroscopically proven partial graft tears. In both cases the torn anterior graft fibers were flipped into the intercondylar notch, mimicking anterior arthrofibrosis, i.e., a ''cyclops lesion,'' on MR imaging. Careful review of the direction of graft fibers on MR imaging in the ''pseudocyclops'' lesions can help differentiate these partial tears from the fibrosis of a true cyclops. The ''pseudocyclops'' lesion is a previously undescribed MR imaging sign of partial ACL graft tear. Larger studies are required to determine the sensitivity and specificity of the sign, as well as the clinical importance of these partial graft tears. (orig.)

    Full Text Available ABSTRACT OBJECTIVE: To evaluate the clinical results among patients undergoing arthroscopic repair of circumferential labral lesions. METHODS: This was a retrospective study on 10 patients who underwent arthroscopic repair to circumferential labral lesions of the shoulder, between September 2012 and September 2015. The patients were evaluated by means of the Carter-Rowe score, DASH score, UCLA score, visual analog scale (VAS for pain and Short-Form 36 (SF36. The average age at surgery was 29.6 years. The mean follow-up was 27.44 months (range: 12-41.3. RESULTS: The mean score was 16 points for DASH; 32 points for UCLA, among which six patients (60% had excellent results, three (30% good and one (10% poor; 1.8 points for VAS, among which nine patients (90% had minor pain and one (10% moderate pain; 79.47 for SF-36; and 92.5 for Carter-Rowe, among which nine patients (90% had excellent results and one (10% good. Joint degeneration was present in one case (10%, of grade 1. We did not observe any significant complications, except for grade 1 glenohumeral arthrosis, which one patient developed after the operation. CONCLUSION: Arthroscopic repair of circumferential labral lesions of the shoulder through use of absorbable anchors is effective, with improvements in all scores applied, and it presents low complication rates. Cases associated with glenohumeral dislocation have lower long-term residual pain.

    The development of squamous cell carcinoma from oral lichen planus is controversial. We report a case of intraoral squamous cell carcinoma, which presents together with lesions of oral lichen planus. The aim of this report was to analyze the problem to distinguish between the incipient changes of squamous cell carcinoma from the features described in oral lichen planus, in order to establish an accurate diagnosis of both entities. A 57-year old man with a history of smoking and chronic alcohol intake, who had an ulcerated tumor mass located in the tongue, and bilateral white reticular patches on buccal mucosa and borders of the tongue. The histopathological report was moderately differentiated invasive squamous cell carcinoma and lichen planus respectively. The premalignant nature of OLP is still indeterminate and controversial, this is primarily due to inconsistency in the clinical and histological diagnostic criteria used to differentiate cases of oral lichen planus from lichenoid reactions or other lesions causing intraepithelial dysplasia with high potentially malignant transformation. Oral lichenoid reactions are possibly most likely to develop malignant transformation as compared to the classic OLP lesions.

    Lichen planus is a benign disorder characterized by an itchy, noninfectious skin rash. Though lichen planus is a common papulosquamous disorder affecting about 1-2% of the population, neoplastic transformation of cutaneous lichen planus lesions occurs very rarely and should be borne in mind while treating nonhealing longstanding lesions of lichen planus. Studies suggest an estimated 0.3-3% risk of malignancy in patients with oral lichen planus, however, cutaneous lichen planus does not carry an increased risk of malignant degeneration. We present a case of a 36-year-old male with a 10-year-long history of hypertrophic lichen planus who presented with a nonhealing ulcer in the left popliteal fossa. The patient underwent wide local excision with superficial skin grafting. Postoperative histopathological examination revealed verrucous squamous cell carcinoma complicating lichen planus. In view of underlying structure involvement, adjuvant radiation therapy was given. This case is being reported to emphasize the infrequent possibility of development of malignancy in cutaneous lichen planus, especially if it presents as a longstanding, nonhealing, itchy lesion with patchy areas of depigmentation in the lower limbs.

    This article demonstrates a methodological approach to diagnosing a periapical radiolucency that could not be diagnosed using only basic clinical and radiographic findings. The patient was a 59-year-old Hispanic female with a small tender mass on the lower gingiva associated with tooth #25. Radiographic appearance demonstrated a well-defined radiolucent lesion at the apices of the mandibular incisors. The patient had no significant medical history. Cone-beam computed tomography (CBCT) showed bony expansion of the buccal plate. Differential diagnosis included non-endodontic unilocular radiolucent lesions in the anterior mandibular region. Biopsy findings were consistent with periapical cemento-osseous dysplasia (PCOD). In conclusion, clinical appearance of PCOD varies from non-expansile and asymptomatic to being expansile and sometimes symptomatic. In the latter cases, it may be necessary to use additional diagnostic tools to confirm the diagnosis.

    This is a case report of two patients with cystic lesions in the parotid region. The diagnostic value of CT sialogram is discussed. A 62-year-old male had a swelling in the left parotid region which felt cystic on manual palpation. A CT sialogram clearly demonstrated a cystic mass superficial to the parotid gland. Histologically, the mass was an epidermoid cyst. A 9-year-old male had pain and swelling in the right parotid region which was not reduced by antibiotic therapy. An extraparotid abscess was diagnosed by CT sialogram 14 days after the onset. CT sialogram is effective in differentiating intrinsic from extrinsic parotid lesions and also shows the relationship of the tumor mass to the facial nerve and helps to differentiate between benign and malignant neoplasms.

    Malignant lympho-epithelial lesion of the salivary gland is an undifferentiated squamous cell carcinoma which is associated with a prominent lymphocyte-rich stroma. This study reviews the current literature pertaining to this rare tumour with reference to the single recorded case of malignant lympho-epithelial lesion of the salivary gland presenting in Auckland, New Zealand. Forty-one per cent of patients present with regional lymph node metastases and 20% with distant metastases. Given the rarity of this disease, treatment is controversial. Current data suggest that early radical combined modality treatment using surgery and radiotherapy leads to prolonged survival and cure with 5 year survival rates greater than 50%. 25 refs., 2 tabs., 4 figs

    Long-term follow-up reports on chondroid lesions of the skull base are rarely presented in the literature. There are virtually no data on natural growth rates of these tumors based on MRI obtained over a period of 10 years or longer. We followed a patient who has had such a lesion for more than 12 years. A non-progressive, slight abducens palsy has been the only associated symptom so far. Even though the patient was operated on for an additional intracranial arterio-venous malformation, clinical features and chromosomal testing excluded Maffucci's syndrome. The MRI follow-up in this case provides an extraordinary perspective on the natural history of chondroid skull base tumors. (orig.)

    Various conservative approaches have been utilized to manage large periapical lesions. This article presents a relatively new, very conservative technique known as surgical fenestration which is both diagnostic and curative. The technique involves partially excising the cystic lining, gently curetting the cystic cavity, performing copious irrigation, and closing the surgical site. This technique allows for decompression and allows the clinician the freedom to take a biopsy of the lesion, as well as perform other procedures such as root resection and retrograde sealing, if required. As the procedure does not perform a complete excision of the cystic lining, it is both minimally invasive and cost-effective. The technique and the concepts involved are reviewed in 4 cases treated with this novel surgical approach.

    Here we present a patient with an isolated paracallosal brain lesion who exhibited behavioral changes associated with the corpus callosum syndrome (CCS) including features of the alien hand syndrome (AHS). The CCS is also known as the split-brain syndrome, the syndrome of hemisphere disconnection, the syndrome of brain bisection and the syndrome of the cerebral commissures. Because most reported cases of CCS were caused by tumors which extended beyond the corpus callosum (CC) and did not always induce a complete disconnection, there was much controversy about the role of the CC and the existence of a specific CCS. Aside from surgically based cases, the full complement of the CCS is infrequently clinically encountered. The patient described has a classic CCS from natural causes. This case report is unique in exhibiting a complete CCS with AHS secondary to an ischemic event affecting the left pericallosal region. To our knowledge this is the first case report of such a combination.

    A 16-year-old boy presented with a concealed degloving lesion of the knee, a Morel-Lavallée lesion, 3 weeks after an injury to the right knee while playing basketball. An incidental hematologic finding led to the additional diagnosis of chronic myelogenous leukemia. Morel-Lavallée lesions often can be overlooked and appear to be subcutaneous hematomas. This case was complicated further by a leukemic condition that was likely the causative mechanism for the recalcitrant nature of the lesion in this athlete.

  20. Four cases with localized brain-stem lesion on CT scan following closed head injury

    Cases of primary brain-stem injury following closed head injury, verified by a CT scan, have been increasingly reported. However, most of them have other intracranial lesions in addition to the brain stem, resulting in a poor outcome. The CT scan of 200 cases with severe head injury-Araki's classification of types 3 and 4 - were analysed. Four cases out of them had localized brain-stem lesion without any other significant intracranial injury on a CT scan at the acute stage and had a better outcome than had previously been reported. In this analysis, these 4 cases were studied, and the CT findings, prognosis, and pathogenesis of the localized brain-stem injury were discussed. Follow-up CT of three cases, and taken one month or more later, showed diffuse cortical atrophy. This may indicate the presence of diffuse cerebral injury which could not be seen on CT scans at the acute stage. This atrophic change may also be related with the mechanism of posttraumatic conscious impairment and posttraumatic neurological deficits, such as mental symptoms and impairment of the higher cortical function. Shearing injury is a probable pathogenesis for this diffuse cortical injury. On the other hand, one case did not have any cortical atrophy on a follow-up CT scan. Therefore, this is a case with a localized primary brain-stem injury. Coup injury against the brain stem by a tentorial margin in a case with a small tentorial opening is a possible mechanism producing the localized brain-stem injury. (J.P.N.)

    Reporting clinical and electrodiagnostic characteristics of sport-related ulnar neuropathies at the wrist. Eight sport-related and 45 non-sport-related cases from 53 ulnar neuropathies at the wrist cases over 14 years. Sport-related ulnar neuropathies at the wrist cases were due to cycling (5 cases), kayaking (2 cases), and big-game fishing (1 case). No patient had sensory complaints in ulnar digits, and all had motor impairment. Conduction across the wrist with recording on the first dorsal interosseous muscle was impaired in all cases, with conduction block in 5. Two cyclists showed bilateral ulnar neuropathies at the wrist. All cases recovered within 2 to 6 months with sport discontinuation. Distal lesions of the deep motor branch were more frequent in sport- than non-sport-related cases. The 8 sport-related ulnar neuropathies at the wrist cases involved the deep motor branch. Conduction study to the first dorsal interosseous muscle across the wrist is the key to electrodiagnostics. Bilateral cases in cyclists does not require wrist imaging.

    Korsakoff syndrome is a chronic memory disorder caused by a severe deficiency of thiamine that is most commonly observed in alcoholics. However, some have proposed that focal structural lesions disrupting memory circuits-in particular, the mammillary bodies, the mammillothalamic tract, and the anterior thalamus-can give rise to this amnestic syndrome. Here, the authors present 4 patients with reversible Korsakoff syndromes caused by suprasellar retrochiasmatic lesions compressing the mammillary bodies and adjacent caudal hypothalamic structures. Three of the patients were found to have large pituitary macroadenomas in their workup for memory deficiency and cognitive decline with minimal visual symptoms. These tumors extended superiorly into the suprasellar region in a retrochiasmatic position and caused significant mass effect in the bilateral mammillary bodies in the base of the brain. These 3 patients had complete and rapid resolution of amnestic problems shortly after initiation of treatment, consisting of resection in 1 case of nonfunctioning pituitary adenoma or cabergoline therapy in 2 cases of prolactinoma. The fourth patient presented with bizarre and hostile behavior along with significant memory deficits and was found to have a large cystic craniopharyngioma filling the third ventricle and compressing the midline diencephalic structures. This patient underwent cyst fenestration and tumor debulking, with a rapid improvement in his mental status. The rapid and dramatic memory improvement observed in all of these cases is probably due to a reduction in the pressure imposed by the lesions on structures contiguous to the third ventricle, rather than a direct destructive effect of the tumor, and highlights the essential role of the caudal diencephalic structures-mainly the mammillary bodies-in memory function. In summary, large pituitary lesions with suprasellar retrochiasmatic extension and third ventricular craniopharyngiomas can cause severe Korsakoff

    Angiolipoma of the spinal column is a lesion made up of mature adipocytes with abnormal blood vessels. Around 60 cases have been reported, the majority located in the extradural space, predominantly the dorsal area. We report two cases examined in our hospital by means of plain X ray, computed tomography and magnetic resonance (MR) imaging. We review the literature and the findings with the different imaging techniques, stressing the importance of the use of MR, especially those techniques involving fat suppression, in the preoperative diagnosis of these lesions. In general, they present high signal intensity on T1-weighted images, with some areas of iso/hyposignal in the interior, a finding that differentiates them from lipomatosis, a condition that presents high signal intensify on T1-weighted sequences, but homogeneously. The administration of a paramagnetic contrast agent enhanced the images, but to a lesser extent in lesions with very high signal intensity on T1-weighted images. The signal intensity can be variable or high on T2-weighted sequences. Techniques using fat suppression are especially specific since they enhance the non-lipomatous (angiomatous) component of the lesion. The association of these MR findings with adjacent skeletal changes, consisting of progressive spinal cord compression, should lead to a suspicion of this un-common lesion, which is successfully managed with surgery.

    Every year, 240,000 people are struck by lightning worldwide, causing injuries leading to significant handicaps. Most of the symptoms involve brain lesions; neuromuscular sequelae and myelopathy are less common. We describe five cases of patients struck by lightning with various clinical presentations. The first patient presented painful paresthesias in both upper limbs that disappeared 18 months later; the injury was a plexopathy. The second patient developed proximal weakness in the upper-left limb due to a myopathy. Two patients presented with various motor weaknesses in the lower limbs due to motor neuron disease and myelopathy. The last patient had a transient tetraplegy, which resolved in 5minutes; the diagnosis was keraunoparalysis. Lightning injuries can have many consequences depending on the different mechanisms involved. The clinical presentation is often due to a very focal lesion without any secondary extension. Motor neuron disease probably results from post-traumatic myelopathy. We discuss the ALS-electrocution association, frequently described in the literature. Various peripheral nerve and spinal cord lesions can be seen in lightning strike victims involving myelopathy, motor neuron, muscle and plexus. Clinical syndromes are often atypical but outcome is often favorable. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

    A case of herpes simplex encephalitis (HSE) with thalamic involvement was reported. The patient, a 27-year-old man, was admitted because of abnormal behavior and fever. He exhibited a disturbance of consciousness, meningial signs, and hyperreflexia. A CT scan of the head revealed diffuse brain edema. Acute encephalitis, especially HSE, was suspected, and so the intravenous administration of acyclovir and steroid therapy were started. The titer of herpes simplex Type 1 virus, as measured by CF and ELISA, was found to have increased amounts of serum and cerebrospinal fluid. 5 days after the onset, his consciousness worsened. He could not tell his name and scarely opened his eyes upon pain stimulation. A CT scan at this time showed low-density lesions in the left thalamus, cingulate gyrus, and the posterior portion of the putamen. About 5 days later, his consciousness level was increased, but he was mute. This symptom was thought to be thalamic aphasia, which might be correlative with the low-density lesions shown in the left thalamus by the CT scan. About 30 days after the onset of the disease, his speech became normal, and a CT scan at 51 hospital days showed no abnormality. The etiology of low-density lesions of the left thalamus in the CT scan is speculated to be as follows: firstly, vascular damage of circulation disturbance, and secondly a special affinity of herpes simplex Type 1 virus to the thalamus.

    A solitary tuberculous brain lesion (STBL) can be difficult to distinguish from a glioma, metastasis or other infectious disease, especially from a pyogenic brain abscess. We analyzed the clinical characteristics, diagnostic procedures and outcomes of 24 patients with STBL diagnosed in three centers from France, India and Mexico. We also reviewed 92 STBL cases previously reported in the literature. General symptoms were found in 54% of our patients, including enlarged lymph nodes in 20%. Cerebrospinal fluid was typically abnormal, with lymphocytic pleocytosis and a high protein level. The lung CT scan was abnormal in 56% of patients, showing lymphadenopathy or pachipleuritis. Brain MRI or CT was always abnormal, showing contrast-enhanced lesions. Typically, MRI abnormalities were hypointense on T1-weighted sequences, while T2-weighted sequences showed both a peripheral hypersignal and a central hyposignal. The diagnosis was documented microbiologically or supported histologically in 71% of cases. Clinical outcome was good in 83% of cases. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

    Only seven cases of agnosia for mirror stimuli have been reported, always with an extensive lesion. We report a new case of an agnosia for mirror stimuli due to a circumscribed lesion. An extensive battery of neuropsychological tests and a new experimental procedure to assess visual object mirror and orientation discrimination were assessed 10 days after the onset of clinical symptoms, and 5 years later. The performances of our patient were compared with those of four healthy control subjects matched for age. This test revealed an agnosia for mirror stimuli. Brain imaging showed a small right occipitoparietal hematoma, encompassing the extrastriate cortex adjoining the inferior parietal lobe. This new case suggests that: (i) agnosia for mirror stimuli can persist for 5 years after onset and (ii) the posterior part of the right intraparietal sulcus could be critical in the cognitive process of mirror stimuli discrimination. © The Author 2014.

  9. Focal retrograde amnesia: voxel-based morphometry findings in a case without MRI lesions.

    Directory of Open Access Journals (Sweden)

    Bernhard Sehm

    Full Text Available Focal retrograde amnesia (FRA is a rare neurocognitive disorder presenting with an isolated loss of retrograde memory. In the absence of detectable brain lesions, a differentiation of FRA from psychogenic causes is difficult. Here we report a case study of persisting FRA after an epileptic seizure. A thorough neuropsychological assessment confirmed severe retrograde memory deficits while anterograde memory abilities were completely normal. Neurological and psychiatric examination were unremarkable and high-resolution MRI showed no neuroradiologically apparent lesion. However, voxel-based morphometry (VBM-comparing the MRI to an education-, age-and sex-matched control group (n = 20 disclosed distinct gray matter decreases in left temporopolar cortex and a region between right posterior parahippocampal and lingual cortex. Although the results of VBM-based comparisons between a single case and a healthy control group are generally susceptible to differences unrelated to the specific symptoms of the case, we believe that our data suggest a causal role of the cortical areas detected since the retrograde memory deficit is the preeminent neuropsychological difference between patient and controls. This was paralleled by grey matter differences in central nodes of the retrograde memory network. We therefore suggest that these subtle alterations represent structural correlates of the focal retrograde amnesia in our patient. Beyond the implications for the diagnosis and etiology of FRA, our results advocate the use of VBM in conditions that do not show abnormalities in clinical radiological assessment, but show distinct neuropsychological deficits.

    ''Cold'' lesions on bone scan have been reported in a variety of disease processes, including infection, avascular necrosis, and cysts. We present two cases of children who presented with large ''cold'' areas on technetium bone scans and were treated initially for septic processes. Acute childhood leukemia frequently presents with bone or joint pain, fever, and elevation of the erythrocyte sedimentation rate. Although the diagnosis may be difficult if the characteristic clinical signs and laboratory findings are absent, the presence of anemia should alert the physician to the possibility of malignancy. Bone scanning provides a sensitive method of localizing pathology, but diagnosis requires biopsy or marrow aspiration

    A case of radionecrosis of the brain in a patient previously treated for squamous cell carcinoma of the scalp is presented. Cerebral angiography revealed a mass effect primarily in the right frontal area. Computed tomography showed extensive hemispheric edema. A frontal lobectomy was performed, and the recovery was excellent. The lower limit for brain tolerance for irradiation is about 5000 rads given in five weeks. This dose should not be exceeded when extracranial lesions are treated. Although computed tomography cannot diagnose brain necrosis, specifically, it should, along with the clinical history, be very helpful.

    The choice of surgical approaches for salvage surgery based on the location and invasion of recurrent and residual lesions of nasopharyngeal carcinoma (NPC), surgical results, complications, and survival were assessed. Thirty-seven cases with recurrent and residual lesions of NPC underwent salvage surgery between March 1991 and January 2005 were analysed retrospectively. Of 37 patients, 23 were men and 14 women, with a median age of 46.5 years (26 - 57 years); 4 were at stage I, 10 at stage II, 14 at stage III, and 9 at stage IV; 5 cases were with cervical metastasis, including 3 cases of N1 and 2 cases N2. All recurrent and residual lesions of NPC were determined by biopsy. On the location and invasion of recurrent and residual lesions of NPC, 8 cases underwent endoscopic resection of lesions, 12 cases of the palate nasopharyngectomy, 5 cases of maxillary swing, 4 cases of maxillary swing plus prerenal approach, 2 cases of lateral rhinotomy plus coronal flap approach, and 6 cases transfacial plus nasal pyramid swing approach. Five cases with cervical metastasis received neck dissection in addition to the operations for recurrent and residual lesions of NPC. Postoperatively 31 cases received radiotherapy with dosage of 60 Gy, among them 15 cases with concurrent chemoradiation therapy, and 6 cases with clear surgical margin did not received radiotherapy or chemotherapy. The cases were followed up for 12 - 72 months, with a median of 45 months. Total resection for the recurrent and residual lesions of NPC accounted for 91.8% (34/37) and subtotal resection for 8.2% (3/37). The accident of perioperative complications was 24.3% (9/37). The 3- and 5-year overall disease-free survival rates (DFSR) were 62.1% and 43.3%, respectively. The 3- and 5-year overall survival rates (OSR) were 72.9% and 51.3%, respectively. The 5 year DFSR of cases at stage I-IV were 100%, 40%, 28% and 11% (χ(2) = 10.0, P < 0.01), respectively. The 5 year OSR were 100%, 70%, 35% and 28% (χ(2

    Abstract The diagnosis of solid benign and malignant tumors presents a unique challenge to all noninvasive imaging modalities. Ultrasound is used in conjunction with mammography to differentiate simple cysts from solid lesions. However, the overlapping appearances of benign and malignant lesions make ultrasound less useful in differentiating solid lesions, resulting in a large number of benign biopsies. Optical tomography using near-infrared diffused light has great potential for imaging functional parameters of 1) tumor hemoglobin concentration, 2) oxygen saturation, and 3) metabolism, as well as other tumor distinguishing characteristics. These parameters can differentiate benign from malignant lesions. However, optical tomography, when used alone, suffers from low spatial resolution and target localization uncertainty due to intensive light scattering. Our aim is to combine diffused light imaging with ultrasound in a novel way for the detection and diagnosis of solid lesions. Initial findings of two earlystage invasive carcinomas, one combined fibroadenoma and fibrocystic change with scattered foci of lobular neoplasia/lobular carcinoma in situ, and 16 benign lesions are reported in this paper. The invasive cancer cases reveal about two-fold greater total hemoglobin concentration (mean 119 µmol) than benign cases (mean 67 µmol), and suggest that the discrimination of benign and malignant breast lesions might be enhanced by this type of achievable optical quantification with ultrasound localization. Furthermore, the small invasive cancers are well localized and have wavelength-dependent appearance in optical absorption maps, whereas the benign lesions appear diffused and relatively wavelength-independent.

    The authors report the case of a 7-year-old boy with a history of developmental delay who presented with aggressive behavior. A magnetic resonance (MR) image showed a mass lesion originating from the cerebellar vermis with an atypical folial pattern and contrast enhancement. Histologically, the subtotally resected specimen consisted mostly of neuropil with nodular foci of ganglion cells. Lhermitte-Duclos disease (LDD) was diagnosed in the patient. A retrospective review of the tissue sections showed a nidus of associated astrocytic proliferation, suggesting a diagnosis of ganglioglioma. Five years later, the patient experienced an altered mental state and a facial droop. An MR image revealed a cerebellar mass with cystic areas and an enhancing nodule. The resected tissue specimen consisted primarily of a mixed proliferation of glial and ganglion cells consistent with a ganglioglioma. Two years later, a third craniectomy was performed in the patient for worsening headache and ataxia. Histologically, the tumor showed progressive anaplasia and was most accurately classified as an anaplastic ganglioglioma. Immunohistochemically, most of the tumor cells were immunoreactive for anti-phospho-mammalian target of rapamycin (mTOR) and phospho-S6 ribosomal protein antibodies. In contrast, the subpopulation of neoplastic ganglion cells in the tissue, particularly from the first surgery, did not express phosphatase and tensin homolog deleted from chromosome 10 (PTEN). This immunohistochemical pattern suggests that the large dysplastic ganglion cells (the gangliocytomatous component) forming the greater part of the lesion were associated with activation of the phosphatidylinositol 3-kinase-PTEN/Akt/mTOR signaling pathway, a feature previously reported in LDD. This case represents the first report of an anaplastic ganglioglioma arising in an LDD-like lesion.

    This paper discusses conventional 3-D reconstruction for bone visualization and presents a case study to demonstrate the dangers of performing 3-D reconstructions without careful selection of the bone threshold. The visualization of midface bone lesions directly from axial CT images is difficult because of the complex anatomic relationships. Three-dimensional reconstructions made from the CT to provide graphic images showing lesions in relation to adjacent facial bones. Most commercially available 3-D image reconstruction requires that the radiologist or technologist identify a threshold image intensity value that can be used to distinguish bone from other tissues. Much has been made of the many disadvantages of this technique, but it continues as the predominant method in producing 3-D pictures for clinical use. This paper is intended to provide a clear demonstration for the physician of the caveats that should accompany 3-D reconstructions. We present a case of recurrent odontogenic keratocyst in the anterior maxilla where the 3-D reconstructions, made with different bone thresholds (windows), are compared to the resected specimen. A DMI 3200 computer was used to convert the scan data from a GE 9800 CT into a 3-D shaded surface image. Threshold values were assigned to (1) generate the most clinically pleasing image, (2) produce maximum theoretical fidelity (using the midpoint image intensity between average cortical bone and average soft tissue), and (3) cover stepped threshold intensities between these two methods. We compared the computer lesions with the resected specimen and noted measurement errors of up to 44 percent introduced by inappropriate bone threshold levels. We suggest clinically applicable standardization techniques in the 3-D reconstruction as well as cautionary language that should accompany the 3-D images.

    This article describes a unique case in which both internal and external inflammatory resorption and endodontic-periodontic lesions were present at the same time in the patient's left mandibular first molar. Based on clinical and radiographic findings, it was determined that the nature of this case was a pulpal infection-induced inflammatory resorption and furcation lesion. After root canal therapy, the furcation lesion and external inflammatory resorption were completely resolved. This case indicates that the correct diagnosis of the stimulating factor for tooth resorption and determination of the primary origin of endodontic-periodontic lesions are critical for clinical management and success.

    Obstruction of the hepatic hilum in patients without prior surgery is generally due to hilar adenocarcinoma (Klatskin tumor). However, not all the hilar strictures are malignant. Although uncommon, benign strictures of the proximal bile duct should be taken into consideration in differential diagnosis of Klatskin tumors, since the incidence could reach up to 25% of patients with presumed Klatskin tumor diagnosis. This group of benign proximal bile duct strictures (Klatskin-mimicking lesions) is usually represented by segmental fibrosis and non-specific chronic inflammation. The clinical and imaging features can not differentiate between benign and malignant strictures. Herein, we present a case series of three patients with benign proximal bile duct strictures (representing 4.1% of 73 patients resected with presumptive preoperative diagnosis of Klatskin tumor) and literature review. There are presented the clinical and biochemical features, imaging preoperative workup, surgical treatment and histological analysis of the specimen, along with postoperative outcome. For benign strictures of the hilum limited resections are curative. However, despite new diagnosis tools developed in the last years, patients with hilar obstructions still require unnecessary extensive resections due to impossibility of excluding the malignancy. In all cases of proximal bile duct obstruction presumed malignant, they should be managed accordingly, even with the risk of over-treatment for some benign lesions.

    Full Text Available Pathological lesions in and around a joint can arise from underlying dermis, subcutis, deep muscle, bone or synovium. Clinical presentation can include joint pain, joint swelling, palpable masses and mechanical restriction. Whilst giant cell tumour of tendon sheath, pigmented villonodular synovitis, synovial chondromatosis, lipoma arborescens, juxta articular myxomas and inflammatory arthritis are the better-known conditions of the joint. Intra-articular nodular fasciitis, on the other hand, is less well recognized both clinically and radiologically. It is rarely seen in routine practice and is only described in case reports in the literature. Due to the non-specific clinical and radiological findings as well as the unfamiliarity with the entity, the diagnosis of intra-articular nodular fasciitis is usually clinched only after histological examination. We present a case of intra-articular nodular fasciitis arising in the knee joint which was not suspected clinically or radiologically.

    This cases report confirms the hypothesis that embryonic and maxillofacial growth are influenced by the peripheral nervous system, including the trigeminal nerve (V). So, it's interesting to use the stigma of the trigeminal nerve as landmarks to analyze the maxillofacial volume and understand its growth. The aim of this study is to evaluate the validity of the three-dimensional cephalometric analysis of Treil based on trigeminal landmarks. The first case is a caucasian female child with Goldenhar syndrome. The second case is a caucasian male adult affected by the same syndrome. In both cases, brain MRI showed an unilateral trigeminal nerve lesion, ipsilateral to the facial dysmorphia. The results of this radiological study tend to prove the primary role of the trigeminal nerve in craniofacial growth. These cases demonstrate the validity of the theory of Moss. They are one of anatomo-functional justifications of the three-dimensional cephalometric biometry of Treil based on trigeminal nerve landmarks. © EDP Sciences, SFODF, 2015.

    We aimed to analyze the outcomes of hypofractionated high-energy electron beam radiotherapy for the treatment of keloids. From February 1998 to January 2012, 568 patients with a total of 834 keloids underwent radiotherapy: 826 lesions with postoperative radiotherapy, and 36 with skin-grafting. Lesion size was >5 cm in 335 keloids. An electron-beam of 6 or 7 MeV was used, with a total dose of 18 Gy (two fractions with a 1-week interval) covering the lesion with a 1-cm margin. The time between surgery and radiotherapy was 24–48 h. Skin-grafted patients underwent radiotherapy 10–15 days after the operation. The median follow-up was 40 months (range: 12–160 months). The local control rate was 88.25% (736/834). The relapse rate was 9.59% (80/834), and the time to relapse was 6–28 months (median: 12 months). Univariate analyses showed that gender, age, keloid size, keloid site, skin grafting, and operation-to-irradiation interval influenced the local control rate. Multivariate analysis showed that the relapse rate was correlated with gender (P = 0.048), age (P < 0.01), operation-to-irradiation interval (P < 0.01), keloid site (P < 0.01), surgical method (P = 0.04) and keloid size (P < 0.02). Adverse effects were observed in 9.83% (82/834). No radiation-induced cancers were observed. Hypofractionated high-energy electron beam radiotherapy for keloids yielded excellent outcomes, especially in cases without skin grafting. Early postoperative radiotherapy with limited hypofractionation could be a good choice for keloid treatment. (author)

  5. A Rare Case of Cavitary Lesion of the Lung Caused by Mycoplasma pneumoniae in an Immunocompetent Patient

    Full Text Available Mycoplasma pneumoniae is an atypical bacterium that most commonly causes upper respiratory tract infections, but it can also cause pneumonia, referred to as “walking pneumonia.” Although cavitary lesions are present in a wide variety of infectious and noninfectious processes, those attributable to M. pneumoniae are extremely uncommon; thus, to date, epidemiological studies are lacking. Here, we present a rare case of a 20-year-old male, referred to us from a psychiatric facility for evaluation of a cough, who was found to have a cavitary lesion in the right upper lobe. An extensive workup for cavitary lesion was negative, but his mycoplasma IgM level was high. A computed tomography (CT of the chest confirmed the presence of a cavitary lesion. After treatment with levofloxacin antibiotics, a follow-up CT showed complete resolution of the lesion. Our case is a rare presentation of mycoplasma pneumonia as a cavitary lesion in a patient without any known risk factors predisposing to mycoplasma infection. Early recognition and treatment with an appropriate antibiotic may lead to complete resolution of the cavitary lesion.

    Disseminated lesions in the white matter of the cerebral hemispheres and confluent lesions at the borders of the lateral ventricles as seen on MRI are both considered acceptable paraclinical evidence for the diagnosis of multiple sclerosis. Similar changes are, however, also found in vascular diseases of the brain. We therefore aimed at identifying those additional traits in the infratentorial region, which in our experience are not frequently found in cerebrovascular pathology. We evaluated MR brain scans of 68 patients and found pontine lesions in 71% of cases with a clinically definite diagnosis (17 out of 24) and in 33% of cases with a probable diagnosis (14 out of 43). Lesions in the medulla oblongata were present in 50% and 16%, respectively, and in the midbrain in 25% and 7%, respectively. With rare exceptions all brainstem lesions were contiguous with the cisternal or ventricular cerebrospinal fluid spaces. In keeping with post-mortem reports the morphological spectrum ranged from large confluent patches to solitary, well delineated paramedian lesions or discrete linings of the cerebrospinal fluid border zones and were most clearly depicted from horizontal and sagittal T2 weighted SE-sequences. If there is a predilection for the outer or inner surfaces of the brainstem, such lesions can be considered an additional typical feature of multiple sclerosis and can be more reliably weighted as paraclinical evidence for a definite diagnosis.

    2010-05-01

    A 43-year-old African American male initially presented for a dental evaluation of a recurrent swelling on the buccal aspect of tooth #12. His medical history was unremarkable except for a 20-pack year history of smoking. He was eventually diagnosed as having a necrotic pulp #12, and received root canal treatment. The patient's problem was unresolved, and he was subsequently referred for a periodontal evaluation with a presumptive diagnosis of a periodontal abscess. A flap was reflected from teeth #11 through #15. A buccal furcation invasion was discovered on #12. Shortly thereafter, three distinct roots with three grade III furcation invasions were located. The tooth was deemed untreatable, and was extracted. The thin buccal plate of the extraction socket was preserved using freeze-dried bone allograft to facilitate future prosthodontic replacement. Healing was uneventful. Periodontal open flap debridement surgery was provided for the remainder of the mouth, and the patient was placed on a 3-month recall program. Periodontitis associated with endodontic lesions are among the most daunting diagnostic and therapeutic challenges faced by periodontists. This is particularly true for maxillary premolars with multiple roots. The tooth in this case, once periodontally involved, had a very poor prognosis. The prognosis was further compromised by the pulpal involvement. Therapy consisted of extraction of the tooth to relieve the patient's discomfort and treating the adjacent teeth with periodontal open flap debridement surgery. A review of the literature pertinent to the diagnosis and management of periodontal-endodontic lesions is also presented.

    Full Text Available Abstract Background Brachial plexus lesions as a consequence of carrying a heavy backpack have been reported, but the typical clinical course and long-term consequences are not clear. Here we evaluated the clinical course and pattern of recovery of backpack palsy (BPP in a large series of patients. Methods Thirty-eight consecutive patients with idiopathic BPP were identified from our population of 193,450 Finnish conscripts by means of computerised register. A physiotherapist provided instructions for proper hand use and rehabilitative exercises at disease onset. The patients were followed up for 2 to 8 years from the diagnosis. We also searched for genetic markers of hereditary neuropathy with pressure palsies. Mann-Whitney U-test was used to analyze continuous data. The Fischer's exact test was used to assess two-way tables. Results Eighty percent of the patients recovered totally within 9 months after the onset of weakness. Prolonged symptoms occurred in 15% of the patients, but daily activities were not affected. The weight of the carried load at the symptom onset significantly affected the severity of the muscle strength loss in the physiotherapeutic testing at the follow-up. The initial electromyography did not predict recovery. Genetic testing did not reveal de novo hereditary neuropathy with pressure palsies. Conclusions The prognosis of BPP is favorable in the vast majority of cases. Electromyography is useful for diagnosis. To prevent brachial plexus lesions, backpack loads greater than 40 kg should be avoided.

    Full Text Available BACKGROUND: Endovascular treatment of peripheral arterial occlusive disease has become increasingly frequent in the past few years. Because it is a less invasive procedure, lower morbidity and mortality rates are associated with this form of treatment. OBJECTIVES: To describe the endovascular procedures performed in iliac arteries for the treatment of peripheral arterial occlusive disease. METHODS: This retrospective study assesses 59 cases of iliac artery angioplasty performed according to a specific protocol from January 2004 to February 2010. RESULTS: Mean age of patients was 62 years (minimum: 42, maximum: 89. Thirty seven were male (62.72% and 22 female (37.28%. The main indications for treatment were moderate to severe intermittent claudication in 30 cases (50.84% and rest pain or trophic lesions (critical ischemia in 29 cases (49.15%. Postoperative follow-up included ankle-brachial index measurements and a duplex ultrasound at 30 days, 3 months, 6 months, 12 months, and every 6 months thereafter. Minimum follow-up time was 3 months, and maximum, 72 months (6 years, with primary and secondary patency rates of 91.37 and 94.82%, respectively. CONCLUSIONS: The results of this case series, combined with literature review results, allow to conclude that the endovascular approach is an effective and safe option to treat peripheral arterial occlusive disease in iliac arteries.

    A 71-year-old man visited our hospital for examination of a soft neck mass. Computed tomography and magnetic resonance imaging scans showed a well-circumscribed large lipomatous tumor with multiple nodules inside. Atypical lipomatous tumor or lipoma involving the lymph nodes was considered. Pathological examination of the surgical specimen suggested typical lipoma including multiple metastatic foci from gastric cancer. Subsequent endoscopy revealed a gastric tumor, which was histologically proven to be signet-ring cell carcinoma. Considering these findings, this case was diagnosed as tumor-to-tumor metastasis to lipoma. We present the first such case with imaging and clinical characteristics. (orig.)

    Reasoning and logical thought processes have traditionally been attributed to frontal lobe function or,on the other hand, have been considered as diffuse functions of the brain. However, there is today evidence enough about the possibility to find dissociations in thought processes, depending on logical structure of the experimental tasks and referring to different areas of the brain, frontal and post rolandic ones. To study possible dissociations between thought structures corresponding to categorical and relational logic, on one hand, and propositional logic on the other hand. The case of a brain injured patient with vascular etiology, localized in left frontal parietal cortex, is presented. A specific battery of reasoning tests has been administered. . A differential performance at some reasoning experimental tasks has been found depending on such logical conceptual structures. The possibility of establishing dissociations among certain logical thought and intelectual functions depending on localization of possible brain lesion (frontal versus temporal) is discussed.

    Swan neck deformity (SND) can be the manifestation of an acute trauma. We present a case report of a young basketball player with an acute traumatic SND determined by the single ulnar oblique retinacular ligament rupture. The patient caught a ball directly upon the tip of his right's hand middle finger into extension. He immediately presented a SND with impossibility to actively flex the proximal interphalangeal joint (PIPJ), while preserving active flexion and extension of the distal interphalangeal joint (DIPJ). Hyperextension of PIPJ was reducible with passive mobilization, thus allowing full passive range of motion. The SND was seen to be caused by the lesion of the ulnar oblique retinacular ligament (ORL) on its distal insertion, with consequent dorsomedial migration of the ulnar lateral band. The early surgical distal reinsertion of the ORL allowed the restoration of the original kinematics of the finger flexion-extension.

    Objective: To review PET images of benign lesions with high accumulation of 18 F-FDG and to analyse the possibility of FDG PET imaging for differentiating the benign from the malignant. Methods: 18 F-FDG PET imaging was performed on 19 patients with benign diseases including 13 cases of active tuberculosis and 6 cases of other benign diseases. Positive pathologic or bacteriological results were obtained for all the patients. PET images were evaluated with standardized uptake value (SUV), lesion shapes , and radioactivity distribution. CT or MRI and histopathologic findings also were reviewed. Results: 1) Thirteen patients with active tuberculosis showed high uptake of 18 F-FDG. The SUV was 3.1±1.8. But radioactivity distribution in some lesions was not uniform and there were defect areas in the lesions. Histopathologic findings proved that the defect areas were induced by caseous necrosis. Seven cases of pulmonary tuberculosis showed two or multiple stripe and funicular high accumulation and other lesions displayed high uptake in sheet or irregular shape; 1 case of scrofula and 1 case of splenetic tuberculosis showed defect areas in the lesions; the other scrofula case showed focal intense uptake. Two of lumbar tuberculosis showed intense uptake in the lumbar vertebra, and one of the two cases complicated with the cold abscess showed bilateral high accumulation in the shape of sheet along musculus psoas major. In the peritoneal tuberculosis case, PET images showed diffuse incrassation and intense uptake in peritoneum and mesentery. CT findings revealed that the peritoneum and mesentery thickened. 2) Pulmonary abscess, pulmonary cryptococcus granuloma, cerebral cryptococcus granuloma, pulmonary inflammatory pseudotumor, leiomyoma, and breast adenoma all showed high accumulation in the shapes of nodule or mass. Mean SUV was 4.5±3.1. CT or MRI findings were the same as on PET images shape. Histopathologic work-up did not find necrosis in the lesions. Conclusions

    It is the purpose of this paper to evaluate the low-density lesions of those pediatric cases which were treated at this hospital in the six months beginning July, 1977, using a CT scan, EMI-1010 Type. Among 1500 consecutive cases diagnosed with the CT scan, 300 pediatric cases were included. We discuss particularly eight patients, two with arachnoidal cysts, two with cystic craniopharyngiomas, two with cystic cerebellar astrocytomas and two with Dandy-Walker syndromes, one of which was accompanied by corpus callosum agenesis. The distribution of ages was from 2 to 12 years. We calculated the matrix of each slice of these patients, CT scan in the cystic lesions, the area including the cystic lesion, ventricles and brain tissue, predominantly the white matter or interhemispheric cortex including white matter, without dye enhancement. The x-ray absorption values of the low-density lesions were definitely different according to the nature of the cystic contents. The mean values of x-ray absorption, the standard deviations, and the sample sizes of each area in the matrix were compared statistically with those of cystic lesions. The mean values of the arachnoidal cysts, the contents of which were almost like CSF, were 17 - 21; that of cystic craniopharyngiomas, the contents of which were a thick yellowic fluid with cholesterin crystals, were 23 - 28; those of cerebellar astrocytomas, with Froin positive fluid, were 22 - 24; the cystic lesions of the posterior fossa in the Dandy-Walker syndrome were 8 - 13. The difference in the x-ray absorption values (Hounsfield number) were compared statistically for analyzing the differential diagnosis of these low-density lesions by calculating the P-values. All of these lesions were verified by surgical explorations. (author)

    Full Text Available Abstract: Erythema multiforme (EM is an acute, self-limited, and sometimes recurring skin condition considered to be a hypersensitivity reaction associated with certain infections and medications. A range of medications can trigger the EM. Non-steroidal anti-inflammatory drugs (NSAIDS which are most commonly prescribed for pain relief can also produce rare adverse reactions such as EM. EM is clinically characterized by a and lsquo; and lsquo;minor'' form and a and lsquo; and lsquo;major'' form. Only few reports have stated about oral EM as the third variant of EM. However it is unclear whether EM involving only oral mucosa is a separate entity or is a part of minor form of EM. In this report three cases of EM are discussed , in which two cases involved exclusively oral mucosal lesions and in one case skin manifestations along with oral mucosa was observed. Also the uncommon adverse effects of NSAIDS is highlighted in this report along with its management. [J Contemp Med 2013; 3(3.000: 193-196

    The main objective of this paper was to report the clinical effectiveness of leukocyte- platelet- rich fibrin (L-PRF) in the treatment of a combined endo-periodontal lesion of an upper first premolar. The tooth had a profound abfraction on the vestibular aspect and presented no mobility but revealed a deep pocket measuring of 11 mm on the mesial vestibular aspect and 14 mm on the mesial palatine aspect. The three dimensional image analysis showed total bone loss in the mesial aspect and an extensively bone loss of the vestibular aspect of the vestibular root. Endodontic treatment was performed and periodontal access surgery (surgical periodontal therapy) was done with the application of autologous L-PRF. Three month and 6 months after surgery, the cone beam computed tomography (CBCT) exams showed no bone regeneration in any aspect of the tooth. However, periodontal examination showed a significative improvement in the deepness of surcus. The mesial vestibular aspect had a deep pocket of 3 mm and 5 mm on the mesial palatine aspect showing a reduction in deepness of 8 mm and 9 mm, respectively. The actual treatment for teeth with bad prognosis is the extraction and replacement with implants. Even though implants are capable of restore function and aesthetic, the abuse of this approach have led to the loss of teeth that could be successfully treated with a less invasive technique. The prognosis of teeth with endoperiodontal lesion is poor but could be enhanced with regenerative therapies. Until now there are no clinical trials and just four case report about the treatment of these teeth with platelet rich fibrin.

    Pigmented lesions in decorative tattoos cause diagnostic difficulties at a clinical and dermoscopic level. In cases of laser removal of tattoos, hidden suspicious nevi may be revealed gradually. We describe the first case of a malignant melanoma that developed on a preexisting nevus within a tattoo during and between the phases of laser removal. The patient refused to undergo excision of the nevus until we made excision conditional for continued laser treatment. The English literature reports 16 cases of malignant melanoma developing in tattoos. Correlation between the placement of tattoos and the development of malignant melanoma remains unclear. Our case emphasizes the diagnostic problems of pigmented lesions within tattoos. For safety reasons, tattoos should never be placed on pigmented lesions; if they are, the tattoos should not undergo laser treatment. We suggest an excision before starting laser tattoo removal. Dermoscopic assessments on a regular basis during the period of tattoo removal are recommended.

    Full Text Available We report the case of a 72-year-old woman with malignant melanoma and multiple metastases; the largest tumor was in the ileum. The patient experienced general fatigue and bloody feces for 1 month before consulting a nearby clinic. Blood tests revealed anemia, and fecal occult blood was positive, but no abnormalities were detected using gastrointestinal endoscopy and colonoscopy or the skin of the entire body. Computed tomography images of the chest, abdomen, and pelvic region, and positron emission tomography–computed tomography images of the entire body revealed multiple nodules in the ileum, left mammary gland, left thyroid, right inguinal lymph node, and on the fascia of the right thoracic area and right buttocks. The tumor in the left mammary gland was excised and immunohistochemical analysis revealed that the excised tissue was positive for HMB45, melan-A, and MITF, but negative for S-100 protein. Diagnosed with melanoma with multiple metastases, the patient underwent four cycles of dacarbazine, nimustine hydrochloride, and vincristine (DAV plus interferon beta chemotherapy and one cycle of dacarbazine, nimustine hydrochloride, cisplatin, and tamoxifen (DAC-Tam chemotherapy. Two series of embolizations of the artery feeding the ileum tumors, as well as a series of plasma and red blood cell transfusions, were performed for ileum tumor hemorrhage. The patient was hospitalized eight times, for a total of 204 days during the 1-year survival period before her death from respiratory failure.

    To analyze the clinical characteristics of secondary male hypogonadism induced by sellar space-occupying lesion, explore its pathogenesis, and improve its diagnosis and treatment. We retrospectively analyzed the clinical data about 22 cases of secondary male hypogonadism induced by sellar space-occupying lesion, reviewed related literature, and investigated the clinical manifestation, etiological factors, and treatment methods of the disease. Hypogonadism developed in 10 of the patients before surgery and radiotherapy (group A) and in the other 12 after it (group B). The patients received endocrine therapy with Andriol (n=7) or hCG (n=15). The average diameter of the sellar space-occupying lesions was significantly longer in group A than in B ([2.35±0.71] vs [1.83±0.36] cm, P<0.05) and the incidence rate of prolactinomas was markedly higher in the former than in the latter group (60% vs 0, P<0.01). The levels of lutein hormone (LH), follicle stimulating hormone (FSH) and testosterone (T) were remarkably decreased in group B after surgery and radiotherapy (P<0.01). Compared with the parameters obtained before endocrine therapy, all the patients showed significant increases after intervention with Andriol or hCG in the T level ([0.78±0.40] vs [2.71±0.70] ng/ml with Andriol; [0.93±0.44] vs [3.07±0.67] ng/ml with hCG) and IIEF-5 score (5.00±2.61 vs 14.50±3.62 with Andriol; 5.36±1.82 vs 15.07±3.27 with hCG) (all P<0.01). The testis volume increased and pubic hair began to grow in those with hypoevolutism. The patients treated with hCG showed a significantly increased testis volume (P<0.01) and sperm was detected in 7 of them, whose baseline testis volume was markedly larger than those that failed to produce sperm ([11.5±2.3] vs [7.5±2.3] ml, P<0.01). Those treated with Andriol exhibited no significant difference in the testis volume before and after intervention and produced no sperm, either. Hypothyroidism might be attributed

    Vascular lesions of the orbit, although not malignant, can cause morbidity because of their location near critical structures in the orbit. For the same reason, they can be challenging to remove surgically. Anti-vascular endothelial growth factor (VEGF) drugs are increasingly being used to treat diseases with prominent angiogenesis. Our study aimed to determine to what extent VEGF receptors and their subtypes are expressed on selected vascular lesions of the orbit. Retrospective case series of all orbital vascular lesions removed by one of the authors (JAG) at the Mayo Clinic. A total of 52 patients who underwent removal of vascular orbital lesions. The pathology specimens from the patients were retrieved, their pathologic diagnosis was confirmed, demographic and clinical information were gathered, and sections from vascular tumors were stained with vascular endothelial growth factor receptor (VEGFR), vascular endothelial growth factor receptor type 1 (VEGFR1), vascular endothelial growth factor receptor type 2 (VEGFR2), and vascular endothelial growth factor receptor type 3 (VEGFR3). The existence and pattern of staining with VEGF and its subtypes on these lesions. There were 28 specimens of venous malformations, 4 capillary hemangiomas, 7 lymphatic malformations, and 6 lymphaticovenous malformations. All samples stained with VEGF, 55% stained with VEGFR1, 98% stained with VEGFR2, and 96% stained with VEGFR3. Most (94%) of the VEGFR2 staining was diffuse. Most orbital vascular lesions express VEGF receptors, which may suggest a future target for nonsurgical treatment. Copyright © 2016 American Academy of Ophthalmology. Published by Elsevier Inc.

    The treatment of hepatic metastasis of colon cancer was in progress by new biochemical agents. Generally, a resection was the first alternative treatment against hepatic metastasis of colon cancer, but new antitumor agents were more effective than conventional antitumor agents. Disappearance of metastasis for colon cancer treated with only antitumor agents was commenced to report. We were experienced a case of transverse colon cancer without a recurrence lesion after five years from the resection of hepatic metastasis. A case was a 77-year-old man. He was operated against transverse colon cancer in February 2003. Pathological stage was ss, n0, Stage II. In April 2004, serum CEA was increased. CT examination was not detected a hepatic metastasis but ultrasound examination and MRI detected the metastasis at S7 lesion in the liver. In July 2004, he was admitted to S-1 and PSK until October 2004. In December 2004, the lesion of hepatic metastasis was reduced and serum CEA was decreased. But in September 2005, the metastatic lesion was re-grown. A resection for hepatic metastasis was executed in November 2005. After the resection for hepatic metastasis, he was admitted to UFT/ UZEL from January 2006 to October 2006. Present time( June 2011), the lesion of recurrence was not detected by several examinations (CT, MRI, Ultrasound etc).

    Cat scratch disease is not a common disease in immunocompetent patients. Its association with bone lesions is rare. A patient with bone complain and radiologic alterations of bone lesion must be investigated for this disease. A simple story can make the differential diagnosis with more complex disease like Ewing sarcoma or eosinophilic granuloma. (author)

    Recently there has been an increase in the request to the radiologists from surgeons to localize nonpalpable breast lesions suspicious for malignancy. Currently there are several needles used for this purpose. The authors present here a new retractable barb needle which consists of a coaxial system with a 20-gauge outer cannula and a 23-gauge inner cannula with a sharp stylus with a hook spring wire soldered to it. The main advantage of this needle over other systems is the ability of the barb to be retracted and the needle repositioned. Other advantages are the strong anchoring properties of the barb, permitting retraction by the surgeon and ending fear of dislodgement, breaking, or transection as experienced with other systems. This system also lowers the radiation exposure to the patients since only one confirmatory radiograph is necessary after optimal positioning of the needle as opposed to two with the most popular system used currently. The authors have done 60 localizations in 58 patients with no failures or major complications. The area in question was successfully sampled in all cases. The authors' referring surgeons prefer this needle over other commercially available types

    This study describes the case of an 8-year-old boy who developed a genuine migraine after the surgical excision, from the right occipital lobe, of brain abscesses due to selective infestation of the cerebrum by Entamoeba histolytica. After the surgical treatment, the boy presented daily headaches with typical migraine features, including right-side parieto-temporal pain, nausea, vomiting, and photophobia. Electroencephalography (EEG) showed epileptiform discharges in the right occipital lobe, although he never presented seizures. Clinical and neurophysiological observations were performed, including video-EEG and polygraphic recordings. EEG showed "interictal" epileptiform discharges in the right occipital lobe. A prolonged video-EEG recording performed before, during, and after an acute attack ruled out ictal or postictal migraine. In this boy, an occipital lesion caused occipital epileptiform EEG discharges without seizures, probably prevented by the treatment. We speculate that occipital spikes, in turn, could have caused a chronic headache with features of migraine without aura. Occipital epileptiform discharges, even in absence of seizures, may trigger a genuine migraine, probably by means of either the trigeminovascular or brainstem system. © EEG and Clinical Neuroscience Society (ECNS) 2014.

    Spindle cell carcinoma of the breast is a rare tumor. This tumor can proliferate rapidly and cause cystic changes because of internal tissue necrosis. We evaluated a 54-year-old woman with right breast lump. Mammography showed a category four mass with a diameter of 2.5 cm. Ultrasonography (US) revealed a complex cystic lesion, and fine-needle aspiration (FNA) cytology demonstrated bloody fluid and malignant cells. Partial breast resection and sentinel lymph node biopsy were performed. Immunohistology revealed spindle cells with positive results for cytokeratin (AE1/AE3) and vimentin, partially positive results for s-100, and negative results for desmin and α-actin. The pathological stage was IIA, and biochemical characterization showed that the tumor was triple negative. Six courses of FEC-100 chemotherapy (5-fluorouracil 500 mg/m 2 , epirubicin 100 mg/m 2 , and cyclophosphamide 500 mg/m 2 ) were administered. Radiotherapy was performed. This case is discussed with reference to the literature

    An unusual case of an endodontic-periodontal lesion in a 29-year-old man resulting from a habit of opening beer bottle (metal) caps using his mandibular left molar is reported. The patient had been a chronic alcoholic with several emotional problems and was unaware of the injurious nature of his habit. Thus, the importance of a detailed case history and assessment of psychosocial aspects for an accurate diagnosis of such conditions is highlighted.

    2011-01-01

    The authors describe a rare case of metastatic bronchogenic adenocarcinoma in a 55-year-old man presenting with concomittant solitary lytic skull lesion and ischaemic stroke. Metastatic bronchogenic carcinoma is known to present as lytic skull lesions. Primary brain tumours are also known to cause ischaemic brain injury. An underlying stroke risk may be exagerated by cranial tumour surgery. Patients with brain tumours are well known to be predisposed to an increased risk of developing thromboembolic disease. It is unusual to see metastatic bronchogenic adenocarcinoma presenting as ischaemic stroke with a background of concomittant cerebral metastasis. The aetio-pathogenesis of this rare occurrence is discussed with a review of literature.

    This study aims to discuss clinical characteristics, image manifestation and treatment methods of temporal bone lesions with facial paralysis as the main manifestation for deepening the understanding of such type of lesions and reducing erroneous and missed diagnosis. The clinical data of 16 patients with temporal bone lesions and facial paralysis as main manifestation, who were diagnosed and treated from 2009 to 2016, were retrospectively analyzed. Among these patients, six patients had congenital petrous bone cholesteatoma (PBC), nine patients had facial nerve schwannoma, and one patient had facial nerve hemangioma. All the patients had an experience of long-term erroneous diagnosis. The lesions were completely excised by surgery. PBC and primary facial nerve tumors were pathologically confirmed. Facial-hypoglossal nerve anastomosis was performed on two patients. HB grade VI was recovered to HB grade V in one patient. The anastomosis failed due to severe facial nerve fibrosis in one patient. Hence, HB remained at grade VI. Postoperative recovery was good for all patients. No lesion recurrence was observed after 1-6 years of follow-up. For the patients with progressive or complete facial paralysis, imaging examination should be perfected in a timely manner. Furthermore, PBC, primary facial nerve tumors and other temporal bone space-occupying lesions should be eliminated. Lesions should be timely detected and proper intervention should be conducted, in order to reduce operation difficulty and complications, and increase the opportunity of facial nerve function reconstruction.

    Anatomically the pulp and periodontium are connected through apical foramen, and the lateral, accessory, and furcal canals. Diseases of one tissue may affect the other. In the present case report with two cases, a primary periodontal lesion with secondary endodontic involvement is described. In both cases, root canal treatment was done followed by periodontal therapy with the use of platelet-rich fibrin (PRF) as the regenerative material of choice. PRF has been a breakthrough in the stimulation and acceleration of tissue healing. It is used to achieve faster healing of the intrabony defects. Absence of an intraradicular lesion, pain, and swelling, along with tooth stability and adequate radiographic bone fill at 9 months of follow-up indicated a successful outcome.

    To emphasize the importance of primary endodontic treatment when dealing with endo-perio lesions and to demonstrate the considerable healing potential of the endodontic aspect. After several years of unsuccessful symptomatic periodontal treatment, an advanced endo-perio lesion on a right-mandibular first molar was successfully treated by root-canal treatment and hemisection after the re-evaluation of the lesion. This successful treatment appeared to have a positive effect on the patient's general well-being. The origin of a combined endo-perio lesion is indicated by its clinical and radiographic appearance. The periodontal situation is often misinterpreted. The prognosis for the endodontic element of treatment is excellent. Local pathologic processes in the oral cavity may affect a patient's general health.

    Vascular anomalies such as hemangiomas or vascular malformations can produce negative esthetic effects in the maxillofacial region. These negative effects are the main complaints of patients. The clinical therapeutic efficacy of cryotherapy and sclerotherapy in the treatment of these lesions was evaluated in 10 patients who were clinically diagnosed with vascular lesions. Lesions were submitted to either cryotherapy or sclerotherapy, and follow-up showed that cryotherapy and sclerotherapy both were clinically effective in treating oral vascular lesions. Cryotherapy is an easy to perform method that requires only 1 session, but the high cost of the equipment is a limiting factor. Sclerotherapy is a noninvasive treatment widely accepted by patients, but more than 1 session is required.

    One patient was a 71-year-old man who had been treated with radiation therapy mainly using grenz rays for 8 years since 1976 for pustulosis on the bilateral planta pedis. The other was a 47-year-old woman who had received it for 3 months during summer time for 5 years since 1973. In both patients, histological examination of the epidermis showed actinic keratosis (AK)-like lesions, presumabley being bowenoid type. Malignant transformation of chronic radiation dermatitis is considered attributable to lesions analogous to AK, and AK lesions are frequently associated with Bowen's disease arising in chronic radiation dermatitis. Thus AK-like lesions of bowenoid type, as seen in these two patients, seems to be sometimes confused with Bowen's disease attributable to chronic radiation dermatitis. (N.K.).

    Full Text Available AIM: To investigate the clinical characteristics and follow-up of 191 patients with lacrimal glandoccupying lesions. METHODS: We selected 191 patients(221 eyeswith lacrimal gland occupancy from January 2011 to August 2015. All patients underwent lacrimal gland tumor removal and were followed up for 1a. RESULTS: In the 191 patients(221 eyes, 44 were male(49 eyesand 147 were female(172 eyes. There were inflammatory lesions in 171 eyes, constituted by IgG4 sclerosing dacryocystitis 66 eyes, 27 eyes of chronic lacrimal gland, lacrimal gland prolapse with inflammatory enlargement 54 eyes, Grave's disease in 24 eyes; 16 eyes of lymphoid hyperplastic lesions, constituted by malignant lymphoma in 6 eyes, benign lymphoid hyperplasia in 10 eyes; epithelial lesions in 34 eyes, constituted by pleomorphic adenoma in 26 eyes, 2 eyes of pleomorphic adenocarcinoma, adenoid cystic carcinoma in 3 eyes, 3 eyes of adenocarcinoma. Lacrimal glandoccupying lesions with IgG4 sclerosing dacryocystitis, lacrimal gland prolapse associated with inflammatory enlargement were the most common, of which 159 eyes of Han, Uighur 36 eyes, Kazak 16 eyes, 10 eyes of Mongolian. After surgery, mainly symptoms were dry eye, crying with no tears, with bilateral lacrimal gland removed significantly, but the local use of artificial tears can ease those symptoms with no serious adverse reactions. CONCLUSION: History and imaging characteristics of lacrimal gland-occupying lesions give a great help to the diagnosis and differential diagnosis. In Xinjiang region, lacrimal gland, with non-epithelial lesions is the most common, followed by epithelial lesions, occurred in the Han, Uighur patients, and rare occurred in other ethnic. Dry eye after surgery and crying with no tears are the main symptoms. Patients with short course of disease and dry eye tend to delay the removal of patients.

    Full Text Available Crossed aphasia in dextral (CAD refers to aphasia occurring after right brain damage in dextral persons. CAD is a rare phenomenon in the world and there has not been any report of crossed aphasia in Persian, that is why we measured to report a Persian patient with crossed aphasia and this is a first report of incidence of CA in Persian. In this case report study, we offered a complete report of a 31-year-oldright handed man with right hemisphere lesion who experienced aphasia after his brain injury. We assessed the patient with Persian version of Bilingual Aphasia Test (BAT, Test of Anomia and Apraxia. In addition, more than 100 utterances of connected speech were gathered and analyzed. According to the results of anomia and apraxia tests, he was at normal level in both of them, but he couldn’t get complete score in BAT, the worst score was achieved in making sentence subtest of BAT. He also had deficits in the syntactic comprehension, grammaticality judgments, lexical decision, verbal fluency and reading comprehension subtests of BAT. Linguistic analysis of his connected speech indicated low speech rate and deficit in using prepositions, compound nouns and verbs. The results confirmed the existence of aphasia and incoherent and non-cohesive speech. The reason of the latter could be deficit in using complex sentences and discourse marker (grammatical problems and circumlocution, deficit in topic maintenance , using pronoun ambiguouslyand selecting inappropriate words for convey meaning (pragmatic problems related to right hemisphere problem .In sum, this patient showed combination of aphasia, agrammatism, and right hemisphere damage( pragmatic deficit together.

    Self harm is a great diagnostic and treatment challenge. In addition, psychocutaneous conditions are rare in the pediatric population and may therefore be misdiagnosed. Dermatitis artefacta is a psychocutaneous syndrome, which is a subgroup of the general spectrum of self-inflicted skin lesions. Dermatitis artefacta encompasses an array of different clinical manifestations, including purpura. Factitious purpura has rarely been reported in children. Case report and review of the literature. We describe two Caucasian patients (9-year-old boy and 10-year-old girl) with striking purpuric lesions diagnosed as factitious purpura. The clinical lesions were similar, but the underlying psychological problems differed significantly (depression and stress). The current state of knowledge of dermatitis artefacta in children and adolescents was reviewed. The presence of purpura in children and adolescents typically causes extensive intervention programs due to the possible serious pathological consequences. The two cases demonstrate a need for a high degree of attention to psychological disturbances, lesional evolution, and distribution once the suspicion is established. © 2014 The International Society of Dermatology.

    Full Text Available Introduction: Richner-Hanhart syndrome (tyrosinemia type II is a rare autosomal recessive disease associated with high serum tyrosine levels caused by the deficiency of tyrosine ami-notransferase enzyme. Case Report: We report a 7-year-old female patient with complaints of hyperkeratosis lesions of palms and soles which started 3 years ago. Chromatography of serum amino acids showed a tyrosine level of 120micromole/L (normal range: 22-87. She had normal ophthalmologic examination and mild mental retardation was detected. One month after the tyrosine- and phenylalanine-restricted diet, her tyrosine level dropped to 42 micromol/L level, her keratotic lesions subsided, and a symptomatic relief in learning was achieved. Conclusion: Tyrosinemia type II should be suspected in patients demonstrating dermatologic signs, especially palmoplantar keratosis, associated with bilateral pseudodendritic corneal lesions unresponsive to antiviral therapy and mild to moderate mental retardation, although our patient without ophthalmic lesions is a very rare case of this syndrome.

    The early and correct diagnosis of cardiac implantable electronic device (CIED) infections is critical given that early aggressive treatment with complete removal of the system along with antimicrobial therapy dramatically improves outcomes. Pocket infection manifested by local signs of inflammation is the most common form of CIED infections. Conditions mimicking pocket infection have been described in the literature. These include various types of malignancy and rarely allergic reactions/contact dermatitis to pacemaker compounds. We aimed to describe skin lesions and disorders over the pocket area that mimic CIED infection. We present a series of 5 cases with skin lesions that mimic pocket infection. We document these cases with corresponding photographs. Most of them have not been described in this setting. We report the following cases of conditions that proved not to be CIED infection: One case of superficial cellulitis, one case of herpes zoster over the pocket area, one case of spontaneous bruising over the pocket a long time after implantation in a patient taking oral anticoagulation, and 2 cases of contact dermatitis due to prolonged postoperative application of povidone iodine. All cases had favorable outcome after conservative treatment and no CIED infection was developed during follow-up. Clinicians should be aware of rare conditions that mimic CIED infection. Incorrect diagnosis of these disorders may falsely lead to CIED extraction. This article is protected by copyright. All rights reserved. This article is protected by copyright. All rights reserved.

    The concept of autoimmune pancreatitis has recently been established, and ultrasonographic findings we obtained from five cases consistent with autoimmune pancreatitis are reported here. Case 1, a 77-year-old man, was admitted complaining of loss of body weight. Serum hepatobiliary enzymes and γ-globulin levels were elevated, and antinuclear antibody was positive, Abdominal ultrasonography showed dilatation of the intrahepatic bile duct, wall thickening of the common bile duct and hypoechoic swelling of the pancreatic head and body. ERCP revealed multiple stenosis of the intra-and extra-hepatic bile ducts, and diffuse irregular narrowing of the main pancreatic duct. The patient complained of thirst, and the minor salivary gland was examined histologically. Our diagnosis was Sjögren syndrome accompanied by sclerosing cholangitis and a pancreatic lesion. Obstructive jaundice also developed, and PTCD was therefore performed. Both the pancreatic swelling and multiple stenosis of the bile duct improved after steroids were administered. Case 2, a 71-year-old man, was admitted with jaundice. Abdominal ultrasonography showed hypoechoic swelling of the pancreas. ERCP showed stenosis of the common bile duct in the pancreatic head region and diffuse irregular narrowing of the main pancreatic duct. Histological examination of the minor salivary gland suggested Sjögren syndrome. Steroids were therefore administered because the presence of both hyper-γ-globulinemia and positive antinuclear antibody suggested involvement of the autoimmune mechanism. Steroid therapy improved the jaundice as well as the findings from the cholangiograms and pancreatograms. We also encountered three similar cases, all consistent with the concept of autoimmune pancreatitis. The ultrasonographic findings of the pancreatic lesion (1) showed them as homogeneous and markedly hypoechoic areas and, (2) visualized the main pancreatic duct in the lesion, which facilitated a differential diagnosis of the

    Breast cancer has emerged as a leading site of cancer among women in India. Fine needle aspiration cytology (FNAC) has been routinely applied in assessment of breast lesions. Cytological evaluation in breast lesions is subjective with a "gray zone" of 6.9-20%. Quantitative evaluation of nuclear size, shape, texture, and density parameters by morphometry can be of diagnostic help in breast tumor. To apply nuclear morphometry on cytological breast aspirates and assess its role in differentiating between benign and malignant breast lesions with derivation of suitable cut-off values between the two groups. The present study was a descriptive cross-sectional hospital-based study of nuclear morphometric parameters of benign and malignant cases. The study included 50 benign breast disease (BBD), 8 atypical ductal hyperplasia (ADH), and 64 carcinoma cases. Image analysis was performed on Papanicolaou-stained FNAC slides by Nikon Imaging Software (NIS)-Elements Advanced Research software (Version 4.00). Nuclear morphometric parameters analyzed included 5 nuclear size, 2 shape, 4 texture, and 2 density parameters. Nuclear morphometry could differentiate between benign and malignant aspirates with a gradually increasing nuclear size parameters from BBD to ADH to carcinoma. Cut-off values of 31.93 μm 2 , 6.325 μm, 5.865 μm, 7.855 μm, and 21.55 μm for mean nuclear area, equivalent diameter, minimum feret, maximum ferret, and perimeter, respectively, were derived between benign and malignant cases, which could correctly classify 7 out of 8 ADH cases. Nuclear morphometry is a highly objective tool that could be used to supplement FNAC in differentiating benign from malignant lesions, with an important role in cases with diagnostic dilemma.

    Full Text Available Purpose: The treatment of oral mucosal lesions and mucosal hypertrophy in particular, is most often achieved by an excision with or without covering the surface of the wound. The platelet rich fibrin membrane (PRFm is an autogenous product containing platelets and leukocytes and their secreted growth factors and cytokines. The purpose of the presented clinical case is to describe a new, recent technique used for the covering of mucosal wounds left after the removal of pathological lesions. Material and Methods: On a single patient mucosal hypertrophy was removed by an excision with scalpel and the resulting surgical wound was covered with an autogenous PRF membrane. Postoperatively the healing process was followed on the 7th, 14th and 30th day. Results: The healing period went smoothly with minimal postoperative discomfort and no complications. Conclusion: The results of the presented clinical case demonstrate that the PRF membrane can successfully be used to cover postoperative mucosal defects.

    Tactile agnosia has been described after lesions of the primary sensory cortex but the exact location and extension of those lesions is not clear. We report the clinical features and imaging findings in a patient with an acute ischemic stroke restricted to the primary sensory area (S1). A 73-year-old man had a sudden onset of a left alien hand, without left hemiparesis. Neurological examination showed intact primary sensory functions, but impaired recognition of shape, size (macrogeometrical) and texture (microgeometrical) of objects; damage confined to the post-central gyrus, sparing the posterior parietal cortex was demonstrated on MRI. An embolic occlusion of the anterior parietal artery was suspected as mechanism of stroke. Tactile agnosia with impaired microgeometrical and macrogeometrical features' recognition can result from a single lesion in the primary sensory cortex (S1) in the right parietal hemisphere, sparing other regions of the cerebral cortex which presumably participate in tactile object recognition.

    Osteosarcomas of the jaw are comparatively rare and represent only 2-10% of all osteosarcomas. We herein present a rare case of an osteosarcoma exhibiting the radiographic and histological characteristics of cemento-osseous lesions in the alveolar ridge of the maxilla. A 53-year-old male patient presented with the complaint of gradual swelling of the left maxilla over 4 years. Radiography revealed an ill-defined radioopaque mass, intimately associated with the apices of the involved teeth, without a periosteal reaction. Microscopically, a cementicle-like structure was identified in the alveolar bone. In addition, the lesion exhibited typical characteristics of chondroblastic osteosarcoma in the body of the maxilla. The tumor contained abundant osteoid and cartilage intimately associated with anaplastic tumor cells. The cartilage displayed malignant-appearing cells in lacunae, and there was crowding at the periphery of the lobule where the spindle cells formed sheets. The differential diagnosis included primary osteosarcoma, concurrent cemento-osseous dysplasia and osteosarcoma, or a secondary osteosarcoma based on a pre-existing cemento-osseous lesion. The presence of the cementicle-like structure in the alveolar bone and the involvement of the periodontal ligament and alveolar bone proper were unique in our case. The general invasive growth pattern and the abundance of the irregular tumor bone helped establish the diagnosis of primary osteosarcoma. This case may represent evidence of the pathogenesis of primary osteosarcoma in the jaw.

    Intestinal lesions after radiotherapy for pelvic malignant tumors are of two types: ulcerative colitis with stenosis and hemorrhage sometimes severe and repeated, and ileal involvement with focal ischemic lesions and malabsorption responsible for nutritional disorders. It is difficult to distinguish them from a recurrence of the tumor in spite of endoscopy, arteriography and biopsy. The course in 3 stages is of great value in diagnosis. A reduction in the frequency of such complications may be hoped for by assessment and exclusion of predisposing factors, by strict observance of therapeutic rules. They are serious owing to the marked irreversible conjunctivo-vascular changes and the fragility of the irradiated tissues during operation.

    Although pharmacologic treatments for central giant cell lesions have gained much emphasis, these treatment modalities do not always have successful outcomes, and surgical treatment may be necessary. The purpose of the present study was to report a case of aggressive central giant cell lesion initially treated by nonsurgical methods without satisfactory results, necessitating segmental mandibular resection for definitive treatment and oral rehabilitation. A 20-year-old woman was diagnosed with an aggressive central giant cell lesion in the mandible. The patient was first treated with intralesional corticosteroid injections. Subsequently, the lesion increased in size. Therefore, a second pharmacologic treatment was proposed with salmon calcitonin nasal spray, but no signs of a treatment response were noted. Because of the lack of response, surgical excision was performed, and a mandibular reconstruction plate was installed. At 12 months after surgical resection, the patient underwent mandibular reconstruction with bone grafts. After 6 months, 7 dental implants were installed, and fixed prostheses were made. After installation of the prostheses, the patient experienced persistent mandibular laterognathism, and a mandibular orthognathic surgery was performed to correct the laterognathia. The follow-up examination 4 years after orthognathic surgery showed no signs of recurrence and good facial symmetry. Copyright © 2016 American Association of Oral and Maxillofacial Surgeons.

    In acute ischemic stroke, diffusion weighted imaging (DWI) shows hyperintensities and is considered to indicate irreversibly damaged tissue. We present the case of a young stroke patient with unusual variability in the development of signal intensities within the same vessel territory. A 35-year-old patient presented with symptoms of global aphasia and hypesthesia of the left hand. MRI demonstrated a scattered lesion in the MCA territory. After rtPA therapy the patient received further MRI examination, three times on day 1, and once on day 2, 3, 5 and 43. The posterior part of the lesion showed the usual pattern with increasing DWI hyperintensity and decreased ADC, as well as delayed FLAIR positivity. However, the anterior part of the lesion, which was clearly visible in the first examination completely normalized on the first day and only reappeared on day 2. This was accompanied by a normalization of the ADC as well as an even further delayed FLAIR positivity. We showed that interim normalization of DWI and ADC in the acute phase can not only be found in rodent models of stroke, but also in humans. We propose that DWI lesion development might be more variable during the first 24 h after stroke than previously assumed

    Leukocyte-platelet rich fibrin belongs to a second generation of platelet concentrates that does not need biochemical blood manipulation. It is used for tissue healing and regeneration in periodontal and oral-maxillofacial surgery. We report two cases of hyperplastic gingival lesions treated by exeresis and application of leukocyte-platelet rich fibrin membranes in order to improve and accelerate tissue healing. Two patients (a 78-year-old Caucasian woman and a 30-year-old Caucasian man) were treated for hyperplastic gingival lesions. They underwent to exeresis of lesions and application of leukocyte-platelet rich fibrin membranes. Tissue healing was clinically evaluated after 1, 3, 7, 14 and 30 postoperative days. No recurrences were observed after 2 years of semi-annual follow up. We obtained rapid and good healing of soft tissues probably due to the elevated content of leukocytes, platelets and growth factors in the leukocyte-platelet rich fibrin. Based on our results we suggest the use of leukocyte-platelet rich fibrin to cover wounds after exeresis of oral neoformations such as hyperplastic gingival lesions.

    To evaluate the efficacy of stereotaxic breast core biopsy using a prone table system, and the effects of operator experience, lesion characteristics and number of samples on biopsy results in cases involving nonpalpable breast lesions. We performed stereotaxic core biopsies of 62 nonpalpable mammographic lesions in 61 patients. Subsequent surgical excision was performed in 11 cases with microcalcifications and one case with a mass. We equally divided patients with microcalcifications into two groups (early and late periods) and analyzed the mammographic findings. Correlation of the pathologic results of core biopsy with those of surgical excision were investigated. In two patients, stereotaxic biopsy was impossible due to poor visibility of microcalcifications and thinness of the compressed breast. In 59 patients, core biopsy was successfully performed and specimens were adequate for pathologic examination. The average number of microcalcifications seen on specimen mammography in the two groups was 1.8(range : 0x8) and 2.5(range : 0x4) respectively. In patients from whom less than five and five or more samples were taken, the average number of microcalcifications seen on specimen mammography was 1.5(range : 0x6) and 2.6(range : 0x8), respectively, throughout the whole period. The pathologic findings were fibrocystic change in 50 cases, fibroadenoma in four, ductal carcinoma in situ in four, invasive ductal carcinoma in one, and atypical ductal hyperplasia in one. The agreement rate of pathologic results between core biopsy and surgical excision was 83%(10/12) for malignancy and 75% for histology. In three cases with disagreement between core and surgical pathologic results, the sampling number was small (3x 4 times) and in two of the three cases, microcalcifications were not visible on mammography operator experience and sampling numbers larger than five results in an increased number of microcalcifications in specimens and more reliable core biopsy

    Mucocele-like lesions (MLLs) of the breast are characterized by cystic architecture with stromal mucin and frequent atypia, but it is unknown whether they convey long-term breast cancer risk. We evaluated 102 MLLs that were derived from a single-institution benign breast disease cohort of 13412 women who underwent biopsy from 1967 to 2001. MLLs were histologically characterized by type of lining epithelium, architecture of the lesion, associated atypical hyperplasia (AH), and incidence of breast cancer (14.8-year median follow-up). A relatively large proportion of MLLs (42%) were diagnosed in women older than 55 years. AH was significantly more frequent in MLL patient compared to the cohort overall (27% versus 5%; P Breast cancer has developed in 13 patients with MLL. This frequency is only slightly higher than population expected rates overall (standardized incidence ratio, 2.28; 95% confidence interval, 1.21-3.91) and not significantly different from women in the cohort with (nonatypical) proliferative breast lesions. Younger women (breast lesion that is often associated with coexisting AH. However, in women older than 45 years, MLLs do not convey additional risk of breast cancer beyond that associated with the presence of proliferative disease. Copyright © 2015 Elsevier Inc.

    Full Text Available BACKGROUND Our study have shown the role of MR spectroscopy in lesions whenever results are equivocal or non-conclusive even on MRI. MR spectroscopy can differentiate the lesions, particularly intracranial lesions on the basis of various metabolites. The aims of this study is to diagnose the intracranial lesions and to show the advantage of MR spectroscopy over the conventional MRI, to differentiate the neoplastic from non-neoplastic lesion, to prove the reliability of MR spectroscopy in identifying the different grades of glioma with histopathological correlation as well as to differentiate recurrent tumour from post-operative changes or radiation necrosis. MATERIALS AND METHODS During the period of August 2009 to July 2011, a prospective study of 75 patients was carried out at Department of Radiodiagnosis, Civil Hospital and BJ Medical College, Ahmedabad, Gujarat. MRI was performed on 1.5 Tesla MR scanner (GE HDXT using dedicated head coil. Conventional MR imaging was performed followed by MR spectroscopy using point resolved spectroscopy. After deciding the region of interest voxel was kept and 2D multivoxel proton spectroscopy (TR- 1000 msec, TE- 144 msec, voxel size 20 x 20 mm or single voxel proton spectroscopy (TR- 1500 msec, TE- 35 msec, voxel size 20 x 20 mm was performed and spectra obtained. RESULTS In the present study of 75 patients, the maximum number of patients were between 31 to 50 years of age. The approximate ratio of male: female was 2: 1. In our study sensitivity, specificity, positive predictive value, negative predictive value of MRI are 89%, 87%, 87% and 89% respectively and of MRI + MRS are 100%, 97%, 97% and 100% respectively in tumours. CONCLUSION MRS (Magnetic Resonance Spectroscopy is a non-invasive imaging technique that studies the chemical activity in the brain and detects the presence of certain chemical substances. Through this imaging technique, images and graphs of the brain can be obtained.

    The brain lesions responsible for palatal myoclonus have been established in many patients by autopsies, although they are yet to be demonstrated with radiological methods including X-ray CT. We report here a case of oculo-palatoskeletal myoclonus whose causative lesion was clearly delineated by MRI. A 61-year-old man had been well until 60, when he suddenly lost consciousness followed by right hemiparesis. X-ray CT revealed a small bleeding in the tegmentum of the pons. He recovered from hemiparesis almost completely in several months. In January 1985, a year after the stroke, however, he developed abnormal involuntary movements (AIM) of the right upper and lower extremities, which gradually increased in severity. In April 1985, he was admitted to our hospital because of AIM and gait disturbance. General physical examination was unremarkable with normal mentality and blood pressure 140/80 mmHg. On neurologic examination, the most outstanding finding was spontaneously and synchronously occurring rhythmic movements involving eyeballs and soft palates at a rate of about 2 Hz, more marked on the right. Furthermore, AIM of the right upper and lower limbs were also obvious in synchrony with rhythmic ocular and palatal movements. These AIM of the limbs were more prominent in the proximal portions and augmented with voluntary motions. They persisted while he was wakeful, disappearing in sleep. There were pyramidal tract signs, hemiataxia and hemisensory disturbance on the right as well as truncal ataxia. X-ray CT of the brain failed to demonstrate the lesion, while MRI showed a low intensity lesion in the tegmentum of the mid- and upper pons, which extended on both sides, more dominant on the right, probably involving the right central tegmental tract; the lesion well accepted as responsible for palatal myoclonus occurring ipsilaterally.

    Cat scratch disease is a common infectious disorder caused by Bartonella henselae that is transmitted primarily by kittens. It typically exhibits a benign and self-limiting course of subacute regional lymphadenopathy and fever lasting two to eight weeks. The most severe complication of cat scratch disease is involvement of the nervous system, such as encephalitis, meningitis, and polyneuritis. Peripheral facial nerve palsy associated with Bartonella infection is rare; few reported pediatric and adult cases exist and the precise pathogenesis is unknown. A previously healthy 7-year-old boy presented with fever, cervical lymphadenopathy, and peripheral facial nerve palsy associated with serologically confirmed cat scratch disease. The stapedius muscle reflex was absent on the left side and brain magnetic resonance imaging revealed a mass lesion at the left internal auditory meatus. The patient's symptoms and imaging findings were gradually resolved after the antibiotics and corticosteroids treatment. The suspected granulomatous lesion was considered to have resulted from the host's immune reaction to Bartonella infection and impaired the facial nerve. This is the first case report providing direct evidence of peripheral facial nerve palsy caused by a suspected granulomatous lesion associated with cat scratch disease and its treatment course.

    A 26-year-old woman noticed gradually progressive, right lower leg weakness over a 1.5-month period. Neurological examination revealed right hemiparesis with slightly increased deep tendon reflexes, Babinski's sign on the right side, loss of position sense in the right leg, and slight loss of superficial sensation in the right toes. MR FLAIR images showed a high intensity area measuring 5 x 2 x 3 cm in the left frontal lobe, extending to the outer surface of the body of the corpus callosum and the adjacent right cingulate gyrus. Gadolinium enhancement was seen along the cortex and the outer surface of the body of the corpus callosum. CSF findings showed no pleocytosis, a protein content of 32 mg/dl, a sugar level of 85 mg/dl, and an IgG index of 0.46. The biopsy specimen obtained from the superior frontal gyrus showed perivascular cuffing of T-lymphocytes and some B-lymphocytes, as well as multiple small foci of demyelination. Starting on the second day of admission, the patient was treated with methylprednisolone pulse therapy (1,000 mg/day for 3 days); she was then switched to oral prednisolone (20 mg/day). Thereafter, the patient had two clinical relapses: one was due to a lesion in the dorsal part of the medulla oblongata associated with a disturbance of deep sensation in both hands, and the other was due to a lesion involving the right internal capsule, the globus pallidus, and the caudate nucleus associated with left facial nerve palsy. Visual evoked potentials suggested a demyelinating lesion in the right optic nerve. We suspected a diagnosis of multiple sclerosis based on the presence of more than two clinical episodes of neurological deficits with identifiable lesions on MRI. Multiple sclerosis should be considered in the differential diagnosis of lesions located in the outer part of the corpus callosum and transcallosal bilateral hemispheres on MRI, even though inner callosal lesions are common in multiple sclerosis.

    This case study concerns an 18-year-old bilingual girl who suffered a radiation lesion in the left (dominant) thalamic and temporal region when she was 4 years old. Language and memory assessment revealed deficits in auditory short-term memory, auditory word comprehension, nonword repetition, syntactic processing, word fluency, and confrontation naming tasks. Both languages (English and Dutch) were found to be affected in a similar manner, despite the fact that one language (English) was acquired before and the other (Dutch) after the period of lesion onset. Most of the deficits appear to be related to verbal (short-term) memory dysfunction. Several hypotheses of subcortical involvement in memory processes are discussed with reference to existing theories in this area

    We report 2 cases of a lesion that we term inverted papilloma of the lower female genital tract, occurring in the cervix and upper vagina of 60- and 50-year-old women, respectively. Microscopically, the features were similar to those of inverted transitional papilloma of the urinary bladder with interconnecting islands, trabeculae, and solid sheets of bland transitional epithelium with an inverted growth pattern. There were small foci of squamous and glandular differentiation in the cervical case. Linear array human papillomavirus genotyping revealed human papillomavirus type 42 in both cases. Inverted papilloma in the lower female genital tract is extremely rare with, as far as we are aware, only 3 previously reported similar cases in the cervix and none in the vagina. Our results suggest that these neoplasms when occurring in the lower female genital tract may be associated with low-risk human papillomavirus, perhaps specifically human papillomavirus 42.

    Full Text Available This report describes two patients with chronic Chagas' Heart Disease who developed clinical and laboratorial signs of myocardial infarction. Both patients presented sudden oppressive chest pain, without precipitating factor. In the first case, the highest MB-CK value was 65 IU, 22 hours after the beginning of the pain. On the second case, it was 77 IU at 18 hours after the beginning of the pain. In both cases ECG changes suggesting non-transmural infarction were present. The 99mTc PYP myocardial scintigram of the first case was positive. Coronary angiograms performed on the 18th and 9th day, respectively, after the acute infarction did not display obstructive lesions. Possible mechanisms causing myocardial infarction with normal coronary arteries in Chagas' Disease may include: embolic event's, particularly when there is associated congestive heart failure; coronary thrombosis and coronary spasms.

    Acromegaly results from oversecretion of growth hormone and subsequently insulin growth factor-1. According to some authors, the disease can cause increased prevalence of nodular goitre and thyroid cancer (TC). However, the number of studies comparing acromegalic patients with control groups is low. We aimed to assess the prevalence of thyroid lesions in patients with acromegaly in comparison to an age- and sex-matched control group and to update the meta-analysis previously performed in our department by the same authors. We searched medical documentation of patients with acromegaly treated in our department between 2003 and 2013. The prevalence of thyroid abnormalities was compared with the group of patients with hormonally inactive adrenal incidentalomas. To perform the meta-analytic part of the paper we also searched ten databases to find relevant papers. Two hundred and five patients with acromegaly and 184 patients with incidentalomas were included. Any thyroid lesions were present in 77.6% of patients with acromegaly vs. 63.0% with incidentalomas (p = 0.002), multinodular goitre - 66.8% vs. 47.8% (p = 0.0002), and TC- 5.4% vs. 2.7% (p = 0.21) respectively. For thyroid lesions the pooled odds ratio (OR) was 3.1 (95% confidence interval [CI] 1.8-5.5), and for TCs the OR was 4.5 (95% CI 1.9-10.3). According to our results thyroid lesions were significantly more common in patients with acromegaly; in case of TC the difference was not significant. The updated meta-analysis showed significantly increased prevalence of both disorders. In conclusion, systematic thyroid examination should be an important part of follow-up in case of acromegalic patients. (Endokrynol Pol 2017; 68 (1): 2-6).

    Central nervous system involvement is a rare manifestation of Langerhans cell histiocytosis (LCH), with bone and skin lesions being more frequent. MR remains the investigation of choice for localizing brain lesions. However, due to poor sensitivity of MRI in detecting osseous and pulmonary lesions, it is not used routinely in staging purposes until and unless indicated. We hereby discuss a case of 6-year-old boy of LCH who was referred for 18-F-FDG PET/CT for staging and knowing the extent of the disease, but a lesion in hypothalamus was picked up incidentally on FDG PET-CT study that was confirmed by MRI.

    The Morel-Lavallée lesion (MLL) is a rarely reported closed degloving injury, in which shearing forces have lead to break off subcutaneous tissues from the underlying fascia. Lumbar MLL have been rarely reported to date, explaining that patients are frequently misdiagnosed. While patients could be treated conservatively or with non-invasive procedures, delayed diagnosis may require open surgery for its cure. Indeed, untreated lesions can cause pain, infection or growing subcutaneous mass that can be confused with a soft tissue tumor. We report the clinical and radiological features of a 45-year old man with voluminous lumbar MLL initially misdiagnosed. We also reviewed the relevant English literature to summarize the diagnostic tools and the main therapeutic options. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

    A 49-year-old man presented with a 30-year history of oral and genital aphthous ulcers and joint pain. One day before his admission he developed double vision and weakness in the right extremities. Neurological examination revealed right 5th nerve palsy, left 6th to 18th nerve palsy, left Horner's sign, and motor and sensory impairment in the right upper and lower extremities. X-ray CT showed diffuse, weak, low-density areas in the brainstem. T1 weighted images showed low signals in the left side of the mid-pons, the left tegmentum and the right basis of the upper pons, and the left tegmentum of the midbrain. T2 weighted images showed high signals in the whole pons and the left side of the midbrain. MRI allowed the differentiation of reversible lesions, such as brain edema, and irreversible lesions, such as necrosis and demyelination of the tissue. (Namekawa, K.)

    Purpose: Focal nodular hyperplasia (FNH), a benign hepatic tumor with ill-defined etiology, has been increasingly reported in children treated for extra-hepatic malignancies. Serial imaging or biopsy may be needed when survivors present with liver lesions. This study aims to review the literature, compare them with our institution’s cohort and propose a less invasive diagnostic imaging modality for FNH utilizing Magnetic resonance imaging (MRI) with gadoxetate disodium.

    Full Text Available This report apparently is the first to describe candidosis in reindeer. It is imperative that reindeer kept in corrals during winter and spring for supplementary feeding, are provided clean, dry conditions and that strict hygenic measures are followed. If reindeer on the other hand are kept in dirty, wet and muddy corrals, among other things, skin lesions due to fungal infections may possibly appear rather frequently.

    The objective of this research was to identify clinically significant changes in cognitive functions in three adolescents who underwent surgery for resection of a focal vascular lesion in the frontal lobe. Cognitive functions, executive function, behavior regulation, emotion regulation, and social abilities were assessed prior to surgery, six and 24 months post-discharge. Significant clinical changes were observed during all the assessments. Cognitive changes after surgery are not homogeneous. Most of the significant clinical changes were improvements. Especially the significant clinical changes presented in EF domains were only improvements; these results suggest that EF were affected by the vascular lesion and benefitted by the surgery. After resection of a vascular lesion between 15 and 16 years of age the affected executive functions can continue the maturation process. Our results highlight the importance that assessments must include emotional aspects, even if deficits in these domains are not presented in the acute phase. Rehabilitation methods should promote the development of skills that help patients and their families to manage the emotional and behavioral changes that emerge once they are discharged from the hospital.

    Traumatic lesion to the optic nerve often leads to severe and persistent functional loss. A male patient was transferred to our hospital from the University Eye Clinic of Guadeloupe 5 days after ocular injury caused by a flying fish. Visual function was light perception. The anterior part of the eye and retina were unremarkable. A computer tomography disclosed a fracture of the sphenoid sinus, with a little bone fragment (DD: foreign body) located close to the optic nerve. Therapy had been started with Aminopenicillin combined with clavulan acid (Augmentin) i. v., 500 ml methylprednisolone (Solumedrol) i. v., lysine-acetyl salicylate (Aspegic) and topical application of dexamethasone combined with neomycin/polymyxin B (Maxitrol). We continued this therapy and intensified it by adding nimodipine (Nimotop) 30 1-1-1 and acetazolamide retard (Diamox sustet) 1-0-1. Unfortunately visual function did not recover under therapy. Traumatic lesions of the optic nerve head, especially when due to axial or tangential forces, can lead to severe and irreversible functional loss. Severe traumatic lesions, even bone fractures induced by flying fish are not a seldom encounter in the Caribbean Sea.

    Cryptococcosis is a mycosis caused by yeasts of genus Cryptococcus, mainly the species C. neoformans and C. gattii that can affect humans and animals. These yeasts are widely distributed in the environment and are typically associated with avian droppings and decaying wood. Most infections are related to the respiratory tract, but the central nervous system and cutaneous lesions are also reported in the literature. The present report is a case of cryptococcosis in an 18-month-old unspayed female English Bulldog with the main complaint of weight loss and diarrhea. The presence of two large masses observed in an ultrasound examination leads us to perform an exploratory laparotomy. Considering the size of the lesion and the impossibility of owner to provide intensive care, the consent for euthanasia was requested. The postmortem diagnosis of cryptococcosis was revealed by cytological evaluation, and the involvement of C. gattii VGII was confirmed by isolation and identification tests as well as by the detection of the URA5 gene restriction fragment length polymorphism PCR analysis. Reports in the literature of the involvement of Cryptococcus in gastrointestinal lesions are rare in both human and veterinary medicine. Data about different forms of cryptococcosis are important to provide more knowledge of uncommon clinical presentations of this yeast and therefore improve the diagnoses and decisions for the best therapy.

    We report five cases of multiple giant cell lesions in patients with typical Noonan syndrome. Such association has frequently been referred to as Noonan-like/multiple giant cell (NL/MGCL) syndrome before the molecular definition of Noonan syndrome. Two patients show mutations in PTPN11 (p.Tyr62Asp and p.Asn308Asp) and three in SOS1 (p.Arg552Ser and p.Arg552Thr). The latter are the first SOS1 mutations reported outside PTPN11 in NL/MGCL syndrome. MGCL lesions were observed in jaws ('cherubism') and joints ('pigmented villonodular synovitis'). We show through those patients that both types of MGCL are not PTPN11-specific, but rather represent a low penetrant (or perhaps overlooked) complication of the dysregulated RAS/MAPK signaling pathway. We recommend discarding NL/MGCL syndrome from the nosology, as this presentation is neither gene-nor allele-specific of Noonan syndrome; these patients should be described as Noonan syndrome with MGCL (of the mandible, the long bone...). The term cherubism should be used only when multiple giant cell lesions occur without any other clinical and molecular evidence of Noonan syndrome, with or without mutations of the SH3BP2 gene.

    Extramedullary hematopoiesis (EMH) is a rare disease, where hematological disorder drives extramedullary hematopoietic tumor formation in multiple regions of the body. The present study reports a case of EMH presenting as multiple tumor-like lesions of mediastinum in a 61-year-old male with α-thalassemia, which was subjected to a video-assisted thoracoscopic surgery tissue biopsy to differentiate it from other mediastinal tumors. To date, only three cases of EMH in patients with α-thalassemia have been described in the literature. Patients with EMH typically exhibit no hematological disorder preoperatively and therefore EMH is frequently misdiagnosed. In the present study, along with a literature review of the clinicopathological features of EMH, the diagnosis and treatment of this rare case was discussed, in order to differentiate diagnosis, and particularly to distinguish EHM from extramedullary myeloid sarcoma.

    Elephantiasis nostras verrucosa (ENV) is a rare cutaneous sequela of chronic lymphedema. Treatment of ENV remains poorly elucidated but has historically involved conservative management aimed at relieving the underlying lymphedema, with a few cases managed by surgical intervention. We report a case of a 27-year-old male with primary lymphedema complicated by large painful ENV lesions on his left foot that we excised surgically with good functional and cosmetic results as validated by the patient. To our knowledge, this is the first report of a case of ENV with a pedunculated morphology and the presence of a deep invasive stalk. Copyright © 2015 American College of Foot and Ankle Surgeons.

    Full Text Available Objectives: The aim of this study was to assess the prevalence of oral mucosal lesions (OMLs and dental caries and to evaluate oral health practices among institutionalized orphan-children in Sana′a city, Yemen. Subjects and Methods: A sample of 202 institutionalized male-orphan-children in the main orphanage in Sana′a city, were matched to 202 non-orphan schoolchildren. Clinical examination included assessment of OMLs based on standard international diagnostic criteria and evaluation of dental status using the Decayed/decayed, Missed/missed and Filled/filled (DMFT/dmft index according to World Health Organization recommendations. Demographic data and oral hygiene practices were obtained by interviewing each subject using special questionnaire form. Results: Majority of children were in the 12-15 year age group. Nine types of lesions were reported among orphans; the most common lesions were fissured tongue (24.3%, herpes labialis (7.9% and traumatic ulcers (2.5%. The occurrence of herpes labialis was found to be significantly higher in orphans than in controls (P < 0.01. The prevalence of dental caries was insignificantly lower among the orphans (84.7% compared with the non-orphans (89.61%; P = 0.136. The mean dmft score was significantly lower in orphans than in controls (2.28 vs. 3.82; P = 0.001. Conclusions: The institutionalized children in this orphanage had a high prevalence of OMLs but low prevalence of dental caries, though they revealed poor oral hygiene practices. Effective oral health promotion strategies need to be implemented to improve the oral health and oral health practices of children living in orphanages.

    Cyst-like periapical lesions should be treated initially with conservative nonsurgical procedures. In this case series, we describe the clinical and radiographic outcomes of large cyst-like lesions that were treated by orthograde decompression and long-term intracanal use of calcium hydroxide [Ca(OH)2] mixed with 2% chlorhexidine digluconate. Ten cases of cyst-like periapical lesions involving 15 teeth from 10 patients were selected. Maximal radiographic diameters of the lesions ranged from 11 to 28 mm. Nonsurgical procedures were performed, including apical patency, orthograde puncture of cyst-like exudates, chemomechanical preparation, and placement of intracanal Ca(OH)2/CHX dressings, which were periodically replaced during 6-10 months. The root canals were then filled with gutta-percha and sealer. The follow-up periods ranged from 6 to 24 months, and the outcome was classified as healed, healing, or failure. Nine lesions drained copious exudates after canal patency. One lesion only drained bloody serous exudate after periapical overinstrumentation. In 9 patients, intracanal exudation ceased in the first follow-up visit. At the 24-month follow-up, 6 lesions (60.0%) had healed, and 3 lesions (30.0%) were healing, with the corresponding patients being without clinical signs or symptoms. The case of treatment failure was submitted to surgical treatment. Microscopically, the lesion appeared to be an apical cyst with exuberant extraradicular bacterial biofilms attached to the sectioned root apex. This case series supports the use of nonsurgical methods to resolve larger cyst-like periapical lesions. Published by Elsevier Inc.

    Conclusion : With experienced hands, FNA is safe, cost effective and a reliable technique for preoperative evaluation of palpable breast lumps. FNA features are more informative when combined with physical and radiology findings (Triple test. Fibroadenoma, fibrocystic change and mastitis form the major bulk of benign breast lesions. Epithelioid cells when seen in inflammatory breast FNA smears, tuberculosis must be ruled out. In India, breast carcinoma arises in younger patients as compared to western countries. Grading of breast carcinomas must be done on FNA smears for selecting neoadjuvent therapy. Clinical breast examination and mammography screening in females should be encouraged in developing countries from the third decade onwards for early detection of breast carcinoma.

    To present the successful endodontic management of a maxillary lateral incisor tooth with a periradicular lesion caused by unintentional root damage after orthodontic miniscrew placement. A 22-year-old female was diagnosed with a skeletal Class II, Division 2 malocclusion with Class II molar and canine relationships on both sides. The treatment plan included distalization of the maxillary first molars bilaterally followed by full fixed appliance therapy. For the maxillary molar distalization, an appliance in conjunction with a miniscrew anchorage system was designed. Two months later, the patient came to the clinic with complaints of pain in the maxillary right lateral incisor region. On intraoral examination, intraoral sinus tracts were detected in the maxillary right buccal sulcus and palate. A large radiolucent lesion with a well-defined margin around the root of the maxillary right lateral incisor was seen. Root canal treatment was performed on the maxillary right lateral incisor tooth. The root canal was filled with gutta-percha and AH Plus sealer, using a lateral compaction technique. The final restoration of the tooth was completed using composite, and the tooth was reviewed after 10 months. The tooth was asymptomatic and radiographically showed repair of the lesion. Healing was achieved without any need for further endodontic or surgical intervention. Key learning points • This case illustrates the need to take care with miniscrews when performing orthodontic treatment, especially when the miniscrews are in close proximity to root apices. • The periradicular lesion as a result of miniscrew damage was successfully treated with root canal treatment. © 2011 International Endodontic Journal.

    Full Text Available Brucellosis is a zoonotic infectious disease, which mainly present with lymphoreticular system invovement. However any organ system can be attacked by the microorganism. In this paper we present a 52-year-old female patient who was admitted to the Infectious Diseases Department with complaints of fatigue, arthralgias, fever, and weight loss. In the medical examination and radiological analysis bilateral pleural effusions and hepatosplenomegaly were detected. Serum transaminase levels were two times higher than the upper limits of normal. Abdominal ultrasound revealed sludge in the gallbladder and multiple hypodense splenic lesions (the largest was 1 cm in diameter. Brucella melitensis was isolated from the blood culture of the patient. Rifampicin (600 mg/day and doxycycline (200 mg/day therapy was started. Follow-up chest radiography and ultrasonography revealed the absence of pleural effusion. Splenic lesions and hepatosplenomegaly were totally regressed. The patient has been followed for 3 months after 6 week antibiotic regimen without recurrence. Brucellosis was expected to be the cause of all pathological signs.

    Mild encephalitis/encephalopathy with reversible splenial lesion (MERS) is a rare clinico-radiological entity characterized by the magnetic resonance imaging (MRI) finding of a reversible lesion in the corpus callosum, sometimes involved the symmetrical white matters. Many cases of child-onset MERS with various causes have been reported. However, adult-onset MERS is relatively rare. The clinical characteristics and pathophysiologiccal mechanisms of adult-onset MERS are not well understood. We reviewed the literature on adult-onset MERS in order to describe the characteristics of MERS in adults and to provide experiences for clinician. We reported a case of adult-onset MERS with acute urinary retension and performed literature search from PubMed and web of science databases to identify other adult-onset MERS reports from Januarary 2004 to March 2016. Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline was followed on selection process. And then we summarized the clinico-radiological features of adult-onset MERS. Twenty-nine adult-onset MERS cases were reviewed from available literature including the case we have. 86.2% of the cases (25/29) were reported in Asia, especially in Japan. Ages varied between 18 and 59 years old with a 12:17 female-to-male ratio. The major cause was infection by virus or bacteria. Fever and headache were the most common clinical manifestation, and acute urinary retention was observed in 6 patients. All patients recovered completely within a month. Adult-onset MERS is an entity with a broad clinico-radiological spectrum because of the various diseases and conditions. There are similar characteristics between MERS in adults and children, also some differences.

    Purpose: Most of the patients who died of breast cancer have developed bone metastases. To understand the pathogenesis of bone metastases and to analyze treatment response of different bone remodeling therapies, preclinical animal models are examined. In breast cancer, bone metastases are often bone destructive. To assess treatment response of bone remodeling therapies, the volumes of these lesions have to be determined during the therapy process. The manual delineation of missing structures, especially if large parts are missing, is very time-consuming and not reproducible. Reproducibility is highly important to have comparable results during the therapy process. Therefore, a computerized approach is needed. Also for the preclinical research, a reproducible measurement of the lesions is essential. Here, the authors present an automated segmentation method for the measurement of missing bone mass in a preclinical rat model with bone metastases in the hind leg bones based on 3D CT scans. Methods: The affected bone structure is compared to a healthy model. Since in this preclinical rat trial the metastasis only occurs on the right hind legs, which is assured by using vessel clips, the authors use the left body side as a healthy model. The left femur is segmented with a statistical shape model which is initialised using the automatically segmented medullary cavity. The left tibia and fibula are segmented using volume growing starting at the tibia medullary cavity and stopping at the femur boundary. Masked images of both segmentations are mirrored along the median plane and transferred manually to the position of the affected bone by rigid registration. Affected bone and healthy model are compared based on their gray values. If the gray value of a voxel indicates bone mass in the healthy model and no bone in the affected bone, this voxel is considered to be osteolytic. Results: The lesion segmentations complete the missing bone structures in a reasonable way. The mean

    Full Text Available Purpose: Natural killer (NK cell neoplasm is a rare disease that follows an acute course and has a poor prognosis. It usually emerges from the nose and appears in the ocular tissue as a metastasis. Herein, we describe a case of NK-cell neoplasm in which the eye was considered to be the primary organ. Case: A 50-year-old female displayed bilateral anterior chamber cells, vitreous opacity, bullous retinal detachment, and multiple white choroidal mass lesions. Although malignant lymphoma or metastatic tumor was suspected, various systemic examinations failed to detect any positive results. A vitrectomy was performed OS; however, histocytological analyses from the vitreous sample showed no definite evidence of malignancy, and IL-10 concentration was low. Enlarged choroidal masses were fused together. Three weeks after the first visit, the patient suddenly developed an attack of fever, night sweat, and hepatic dysfunction, and 5 days later, she passed away due to multiple organ failure. Immunohistochemisty and in situ hybridization revealed the presence of atypical cells positive for CD3, CD56, and Epstein-Barr virus-encoded RNAs, resulting in the diagnosis of NK-cell neoplasm. With the characteristic clinical course, we concluded that this neoplasm was a primary intraocular NK-cell lymphoma. Conclusions: This is the first report to describe primary intraocular NK-cell neoplasm. When we encounter atypical choroidal lesions, we should consider the possibility of NK-cell lymphoma, even though it is a rare disease.

    Lichen planus (LP) is a relatively common mucocutaneous disease with autoimmune etiology. Considering its malignancy potential, it is important to define the correct diagnosis, treatment, and clinical follow-up for patients with LP so that the disease is not diagnosed late, thus hindering the chances of curing the disease. This study aims to describe a clinical case of oral squamous cell carcinoma, potentially originated from LP. The patient is undergoing clinical and histopathological follow-up. A 64-year-old Caucasian male patient presented with a proliferative verrucous lesion on the tongue and sought treatment at the School of Dentistry, University of Passo Fundo (UPF), Passo Fundo, Brazil. He claimed the lesion had been present since 1988, and had been initially diagnoses as "oral lichen planus." The physical exam presented three diagnostic hypotheses: plaque-like oral LP, verrucous carcinoma, and squamous cell carcinoma. After incisional biopsy and histopathological analysis, squamous cell carcinoma was diagnosed, probably originating from oral LP. The case study shows that malignancy from oral LP is possible, which justifies periodic clinical and histopathological follow-up, as well as the elimination of risk factors for carcinoma in patients with oral LP.

    The cerebellum is a recent addition to the growing list of cerebral areas involved in the multifaceted structural system that sustains verbal working memory (vWM), but its contribution is still a matter of debate. Here, we present a patient with a selective deficit of vWM resulting from a bilateral cerebellar ischemic lesion. After this acute event, the patient had impaired immediate and delayed word-serial recall and auditory-verbal delayed recognition. The digit span, however, was completely preserved. To investigate the cerebellar contribution to vWM, four experiments addressing the function of different vWM phonological loop components were performed 18 months after the lesion, and results were compared with normative data or, when needed, with a small group of matched controls. In Experiment 1, digit span was assessed with different presentation and response modalities using lists of digits of varying lengths. In Experiment 2, the articulatory rehearsal system was analyzed by measurement of word length and articulatory suppression effects. Experiment 3 was devoted to analyzing the phonological short-term store (ph-STS) by the recency effect, the phonological similarity effect, short-term forgetting, and unattended speech. Data suggested a possible key role of the semantic component of the processed material, which was tested in Experiment 4, in which word and nonword-serial recall with or without interpolating activity were analyzed. The patient showed noticeably reduced scores in the tasks that primarily or exclusively engaged activity of the ph-STS, namely those of Experiment 3, and good performance in the tests that investigated the recirculation of verbal information. This pattern of results implicates the ph-STS as the cognitive locus of the patient's deficit. This report demonstrates a cerebellar role in encoding and/or strengthening the phonological traces in vWM.

  12. A case of pneumothorax following bougie-guided intubation in a patient undergoing excision of an intraventricular space occupying lesion

    Full Text Available A 46-year-old female with intraventricular space occupying lesion was posted for craniotomy and excision of the same. Immediately following routine induction of general anaesthesia and a bougie-guided intubation, she developed increased airway pressures and desaturation associated with a decreased air entry on the right side of the chest suggestive of a right-sided pneumothorax which was confirmed with radio imaging and following the placement of chest drain the saturation improved and airway pressures decreased. To be faced with a pneumothorax following an intubation could be surprising for a non-suspecting anaesthesiologist and it can have important implications especially in neurosurgical cases where a tight control of intracranial pressure is warranted. Hence, this case report emphasises the need for a high index of clinical suspicion for proper management and safe patient outcome.

    Psoriasis, a chronic inflammatory skin disease, is caused by infiltrating lymphocytes and associated cytokines, including tumor necrosis factor (TNF)α, interleukin (IL)-6, and IL-17. Effective treatments, including pathogenesis-based biological agents against psoriasis, are currently under development. Although the role of reactive oxygen species (ROS) in the pathogenesis of psoriasis has been investigated, it remains to be fully elucidated; ROS-targeted therapeutic strategies are also lacking at present. Therefore, the objective of the present study was to assess whether H2, a ROS scavenger, has a therapeutic effect on psoriasis-associated inflammation by reducing hydroxyl radicals or peroxynitrite in the immunogenic psoriasis cascade. Three methods were used to administer H2: Drop infusion of saline containing 1 ppm H2 (H2-saline), inhalation of 3% H2 gas, and drinking of water containing a high concentration (5-7-ppm) of H2 (high-H2 water). Treatment efficacy was estimated using the disease activity score 28 (DAS28) system, based on C-reactive protein levels, and the psoriasis area and severity index (PASI) score, determined at baseline and following each H2 treatment. Furthermore, levels of TNFα, IL-6, and IL-17 were analyzed. The DAS28 and PASI score of the three patients decreased during H2 treatment, regardless of the administration method. The psoriatic skin lesions almost disappeared at the end of the treatment. IL-6 levels decreased during H2 treatment in Case 1 and 2. IL-17, whose concentration was high in Case 1, was reduced following H2 treatment, and TNFα also decreased in Case 1. In conclusion, H2 administration reduced inflammation associated with psoriasis in the three cases examined and it may therefore be considered as a treatment strategy for psoriasis-associated skin lesions and arthritis.

    1989-08-01

    Full Text Available This report describes the first documented case of Erysipelothrix rhusiopathiae endocarditis in Latin America. The patient was a 51-years-old male, moderate alcoholic, with a previous history of aortic failure. He was used to fishing and cooking as a hobby and had his left hand wounded by a fish-bone. The disease began with erysipeloid form and developed to septicemia and endocarditis. He was treated with antibiotics and surgery for aortic valve replacement. There are only 46 cases of E. rhusiopathiae endocarditis reported to date. The authors wonder if several other cases might go unreported for lack of microbiological laboratorial diagnosis.

    This is a 20-year-old female who had diabetes insipidus and disturbance of visual acuity at the age of 10. Because she had been diagnosed as having craniopharyngioma, she received 1000 R by 60 Co in August 1965 (at the age of 16), 4000 R from November to August 1966, and 2600 R in June 1967, a total of 7600 R for one year and ten months. At that time, the left facial palsy was noticed. Incomplete palsy was seen in the left lower extremity in October 1967 (at the age of 18). Disturbances of hearing and speaking appeared in March 1968 (at the age of 19). She complained of high fever (38 0 C) and migraine on the left in December 1974. The skull plain x-ray revealed calcification in the left temporal region of the skull, corresponding to the skin scar caused by 60 Co irradiation. Left carotid arteriography revealed lesions in the left temporal lobe, but no tumor stains. Right carotid arteriography revealed marked stricture in the right middle cerebral artery, and obstruction of the cortical branches. Brain scintigram (sup(99m)Tc) revealed the moduratoly increased activity on both temporal regions. The pneumo-encephalography revealed calcification in the left temporal horn of lateral ventricle. The pathological findings after the operation showed necrosis and calcification of brain tissues caused by intimitis and obstruction of the cerebral vessels. (Kanao, N.)

    Full Text Available 404 sarcoidosis and 404 tuberculosis patients were examined in order to detect correlations between clinical manifestations, psychological adaptation and accentuation of personality traits and granulomatous lesions of respiratory organs in case of sarcoidosis and tuberculosis. All patients had subjective and objective examinations and answered the following questionnaires: Schmieschek questionnaire to identify accentuation of personality traits, clinical questionnaire to detect and evaluate neurotic disorders, Taylor Manifest Anxiety Scale to detect the level of anxiety. It has been found out that sarcoidosis patients are characterized both by asymptomatic course of the disease as well as diverse clinical manifestations: pain syndrome, nodal fever, intoxication with expressed general fatigue, respiratory insufficiency. It is combined with stuck, pedant, cycloid, exalted, emotive accentuations of personality traits, with psychological maladaptation as per the scores of autonomic imbalance, neurotic depression, asthenia, with average high level of anxiety. The following is typical of tuberculosis patients: syndrome of bronchial tree lesions and respiratory insufficiency; distymny, demonstrative, excitable, exalted, anxiety-hypochondriac accentuations of personality traits, with psychological maladaptation as per the scores of autonomic imbalance, obsessive-phobic disorders and hysteria; average high level of anxiety. The strong correlation has been found between the degree of symptoms expression, level of anxiety and psychological maladaptation and the type of patient's accentuation of personality traits.

    Human papillomavirus (HPV) contribution in vulvar intraepithelial lesions (VIN) and invasive vulvar cancer (IVC) is not clearly established. This study provides novel data on HPV markers in a large series of VIN and IVC lesions. Histologically confirmed VIN and IVC from 39 countries were assembled at the Catalan Institute of Oncology (ICO). HPV-DNA detection was done by polymerase chain reaction using SPF-10 broad-spectrum primers and genotyping by reverse hybridisation line probe assay (LiPA25) (version 1). IVC cases were tested for p16(INK4a) by immunohistochemistry (CINtec histology kit, ROCHE). An IVC was considered HPV driven if both HPV-DNA and p16(INK4a) overexpression were observed simultaneously. Data analyses included algorithms allocating multiple infections to calculate type-specific contribution and logistic regression models to estimate adjusted prevalence (AP) and its 95% confidence intervals (CI). Of 2296 cases, 587 were VIN and 1709 IVC. HPV-DNA was detected in 86.7% and 28.6% of the cases respectively. Amongst IVC cases, 25.1% were both HPV-DNA and p16(INK4a) positive. IVC cases were largely keratinising squamous cell carcinoma (KSCC) (N=1234). Overall prevalence of HPV related IVC cases was highest in younger women for any histological subtype. SCC with warty or basaloid features (SCC_WB) (N=326) were more likely to be HPV and p16(INK4a) positive (AP=69.5%, CI=63.6-74.8) versus KSCC (AP=11.5%, CI=9.7-13.5). HPV 16 was the commonest type (72.5%) followed by HPV 33 (6.5%) and HPV 18 (4.6%). Enrichment from VIN to IVC was significantly high for HPV 45 (8.5-fold). Combined data from HPV-DNA and p16(INK4a) testing are likely to represent a closer estimate of the real fraction of IVC induced by HPV. Our results indicate that HPV contribution in invasive vulvar cancer has probably been overestimated. HPV 16 remains the major player worldwide. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Penetrating liver wounds are related to many causes and rank second after blunt abdominal and liver trauma. We will report the clinical and radiological findings of our personal series of patients with penetrating trauma, especially by firearms and stab and cut wounds. We will also try to define the diagnostic workup of these traumas, which is especially based on CT signs of liver damage and associated changes and which is of basic importance for following treatment, both surgical or conservative. In the last seven years we retrospectively reviewed 31 cases of penetrating liver trauma. The patients were 19 men and 12 women, ranging in age 18 to 73 (mean 42), with penetrating liver injuries from firearms (16 patients) and stab (9 cases) wounds; 6 patients had injuries from different causes. Abdominal CT was carried out in emergency with the CT Angiography (CTA) technique in all patients. In the patients with suspected chest and abdomen involvement CT was performed from the mid-chest for accurate assessment of diaphragm and lung bases and to exclude associated pleuropulmonary damage. Penetrating liver wounds were caused by firearms in 70% of cases, by stabbing in 12% and, in the extant 18%, by other causes such as home accidents, road and work traumas, and liver biopsy. In our series, the liver was most frequently involved, especially by firearms wounds; in our 16 cases the most frequent injuries were hemorrhagic tears. We found bullets in the liver in 6 cases. In one case of home accident the patient wounded himself while slicing bread with a long knife, which cut into the anterior abdominal wall and tore the anterior liver capsule, as seen at CTA. Penetrating wounds to liver and abdomen are less frequent than those to the chest. In the past decade the use of CT has changed the diagnostic and therapeutic approach to such injuries completely, decreasing the resort to explorative laparotomy and hepatorrhaphy. Indeed, CT provides a clear picture of the extent and

    Full Text Available We describe the case a spinal cord localization of neurological toxoplasmosis in a HIV-positive patient with Burkitt lymphoma, previously treated with chemotherapy and immunotherapy. This complication occurred while patient was in complete remission of lymphoma, with CD4+ T cell count of 270 /ml, undetectable HIV viremia, and despite the trimethoprim/ sulfamethoxazole prophylaxis. Indeed, we hypothesize that in our patient neurologic toxoplasmosis has been fostered more by previous immuno-chemotherapy than by HIV- related immunodeficiency. On the whole, this case suggests that parameters usually employed to predict the risk for opportunistic infections in HIV-positive people might not apply to patients with HIV-related lymphomas.

    Patients with disorders of consciousness (DOC) have profound functional limitations with few treatment options for improving arousal and quality of life. Zolpidem is a nonbenzodiazepine hypnotic used to treat insomnia that has also been observed to paradoxically improve arousal in those with DOC, such as the vegetative or minimally conscious states. Little information exists on its use in patients with DOC who have intracranial space-occupying lesions. We present a case of a 24-year-old man in a minimally conscious state due to central nervous system lymphoma who was observed to have increased arousal and improved motor function after the administration of zolpidem.

    Extensive gingival recessions associated with cervical abrasions are common among the population. Several different surgical and/or restorative therapies have been proposed to correct these lesions. This manuscript reports the treatment of multiple gingival recessions associated to cervical abrasions. The procedure involved the utilization of subepithelial connective tissue graft (SCTG) combined with coronally advanced flap onto a previously restored root surface. At the postoperative follow-up visits, the success of the restorative/surgical approach was confirmed by the absence of bleeding to probing and periodontal pockets as well as presence of gingival tissue with normal color, texture and contouring. After 18 months of follow-up, the clinical conditions are stable with satisfactory root coverage and periodontal health. An excellent esthetical outcome was achieved and the patient is satisfied with case resolution. PMID:19826605

    Dieulafoy's lesion, also known as a caliber-persistent artery, is a shallow, small, and rare lesion that occurs along the lesser curvature of proximal stomach. It is rare for a Dieulafoy's lesion to present as a mass-like lesion that coexists with gastric cancer. To our best knowledge, we report the first case and histopathological pictures of a mass-like Dieulafoy's lesion coexisting with advanced gastric cancer in the antrum of the stomach. A 57-year-old female presented with a 6-month history of intermittent epigastric dull pain and dyspepsia. Subsequent upper gastrointestinal endoscopy revealed a friable mass that was located between the distal antrum and the pyloric ring. Biopsy revealed it to be an intestinal type adenocarcinoma. Subtotal gastrectomy was performed after neoadjuvant chemotherapy. Grossly, a large irregular plaque-like tumor lesion was noted at the anterior wall of the distal antrum and pylorus ring near the lesser curvature, measuring 5.6 × 4.8 × 1.0 cm. Histopathological examination of the resected stomach revealed that the plaque-like lesion largely consisted of numerous abnormally large-caliber and tortuous arteries in the submucosa. The increased fibrosis of the submucosa resulted in the formation of elevated plaque. The intestinal type adenocarcinoma was noted to be largely confined to the mucosa layer, with focal submucosal and muscular propria involvement. The patient was discharged one week after the subtotal gastrectomy, and she was alive and well 17 months after discharge, with no major complications. This is the first case of a mass-like Dieulafoy's lesion coexisting with advanced gastric cancer at the distal antrum area. This case highlights the possibility of life-threatening gastric bleeding after mucosal resection or biopsy that could be encountered by endoscopists.

    Full Text Available Centrally occurring salivary gland tumors are rare. Because of a considerable overlap between the clinical and histopathological features, this group of tumors often produces a diagnostic difficulty to the clinicians and oral pathologists. Acinic cell carcinoma (ACC is an unusual, low-grade, malignant salivary gland tumor that represents approximately 2% of the salivary gland tumors with almost 90% arising in the parotid gland. The rest involve the submandibular and the minor salivary gland. ACC of the jaw is extremely rare and, to our knowledge, only 8 cases have been reported in the English literature. Herein, a case of primary intraosseous ACC of the mandible in a 31-year-old woman is presented. The present case is unique, as the central ACC has never been reported in a patient in the third decade of life. The complete surgical removal of the tumor was carried out under general anesthesia along with the extraction of teeth #31, #32, #41, and #42. The follow-up period of 1-year was uneventful.

    Full Text Available Abstract Background Neuromyelitis optica (NMO is an idiopathic, severe, inflammatory demyelinating disease of the central nervous system, that causes severe optic neuritis and myelitis attacks. Early discrimination between multiple sclerosis (MS and NMO is important, as optimum treatment for both diseases may differ considerably. Case Presentation We report a case of a patient who initially presented as longitudinally extensive transverse myelitis (LETM, having spastic upper extremities diparesis and spastic paraplegia, C2/C3 sensory level and urinary incontinence, as well as extensive inflammatory spinal cord lesions from C2 level to conus. After 5 months the patient had another attack of transverse myelitis, had electrophysiological findings consistent with optic neuritis, was seropositive for NMO-IgG (aquaporin-4 IgG and thus fulfilled NMO diagnostic criteria. Following treatment of disease attacks with pulse corticosteroid therapy and intravenous immunoglobulins, we included oral azathioprine in a combination with oral prednisone in the therapy. Since there was no significant clinical improvement, we decided to use cyclophosphamide therapy, which resulted in good clinical improvement and gradual decrease of cord swelling. Conclusion In this NMO case report we wanted to emphasize the extensiveness of inflammatory spinal cord changes in our patient, from C2 level to conus. In the conclusion it is important to say that accurate, early diagnosis and distinction from MS is critical to facilitate initiation of immunosuppressive therapy for attack prevention.

    2009-01-01

    Full Text Available Abstract Introduction The improved survival of children with brain tumors has increased concerns about treatment-related sequelae. Growth hormone deficiency is frequently observed after craniospinal irradiation for medulloblastoma. It has been widely reported that growth hormone replacement therapy does not increase the risk of second tumors, but there are reports in the literature of growth hormone, and its downstream mediator insulin-like Growth Factor 1, having an important proinflammatory action. There are few reports, however, on the "in-vivo" induction of edema and symptomatic inflammatory lesions during replacement therapy. Case presentation We report the case of a 7-year-old girl treated for metastatic medulloblastoma who developed growth hormone deficiency 2 years after oncological treatment. Three months after replacement therapy, magnetic resonance imaging showed exacerbation of her brain edema, which was already present after oncological treatment. We consequently suspended the growth hormone until a new magnetic resonance image obtained 3 months later documented a reduction of the inflammatory areas. We then re-introduced somatotropin at lower doses with no further increase in brain edema in subsequent radiological controls. Conclusion This case and its iconography suggest a strong association between growth hormone administration and the exacerbation of inflammatory reactions within the tumor bed. Replacement therapy should be carefully monitored in this particular subset of patients.

    2013-01-01

    Full Text Available The aim of this case report is to present two cases where cone beam computed tomography (CBCT was used for the diagnosis, treatment planning, and followup of large periapical lesions in relation to maxillary anterior teeth treated by endodontic surgery. Periapical disease may be detected sooner using CBCT, and their true size, extent, nature, and position can be assessed. It allows clinician to select the most relevant views of the area of interest resulting in improved detection of periapical lesions. CBCT scan may provide a better, more accurate, and faster method to differentially diagnose a solid (granuloma from a fluid-filled lesion or cavity (cyst. In the present case report, endodontic treatment was performed for both the cases followed by endodontic surgery. Biopsy was done to establish the confirmatory histopathological diagnosis of the periapical lesions. Long-term assessment of the periapical healing following surgery was done in all the three dimensions using CBCT and was found to be more accurate than IOPA radiography. It was concluded that CBCT was a useful modality in making the diagnosis and treatment plan and assessing the outcome of endodontic surgery for large periapical lesions.

    The aim of this case report is to present two cases where cone beam computed tomography (CBCT) was used for the diagnosis, treatment planning, and followup of large periapical lesions in relation to maxillary anterior teeth treated by endodontic surgery. Periapical disease may be detected sooner using CBCT, and their true size, extent, nature, and position can be assessed. It allows clinician to select the most relevant views of the area of interest resulting in improved detection of periapical lesions. CBCT scan may provide a better, more accurate, and faster method to differentially diagnose a solid (granuloma) from a fluid-filled lesion or cavity (cyst). In the present case report, endodontic treatment was performed for both the cases followed by endodontic surgery. Biopsy was done to establish the confirmatory histopathological diagnosis of the periapical lesions. Long-term assessment of the periapical healing following surgery was done in all the three dimensions using CBCT and was found to be more accurate than IOPA radiography. It was concluded that CBCT was a useful modality in making the diagnosis and treatment plan and assessing the outcome of endodontic surgery for large periapical lesions. PMID:23762646

    Morel-Lavallee syndrome is a posttraumatic soft tissue injury in which the subcutaneous tissue is broken off from the underlying fascia, creating a cavity filled with hematoma and liquefied fat. It commonly occurs over the greater trochanter and, rarely, may also occur in the lumbal region.Morel-Lavallee syndrome can be often diagnosed late because of ommitted diagnosis in emergency services. The emergency physician and radiologist must keep this syndrome in mind because early diagnosis can enable conservative management, whereas delayed diagnosis may lead to surgical exploration. In this article,we present the clinical and radiologic features of 2 cases of lumbar Morel-Lavallee syndrome detected after trauma.

    The aim of this study was to analyze the association between the presence of actinic lesions (solar keratosis and non-melanoma skin cancer) and osteoporotic hip fractures in older patients. Both pathologies are common conditions in this age group. Since cumulative sun exposure is difficult to quantify, the presence of actinic lesions can be used to indirectly analyze the association between ultraviolet radiation and osteoporotic hip fractures. This was an observational case-control study. We reviewed the centralized medical records of patients with hip fracture (cases, n = 51) and patients with other diseases hospitalized in the same institution and period (controls, n = 59). The mean age of the patients was 80 ± 8.3 years (range 50-103 years). Differences in maternal hip fracture history were found between cases and controls (14.8 and 8 %, respectively; p = 0.047). Falls history in the past year was higher in cases than in controls (p < 0.0001). Actinic lesions were observed in 32.7 % of patients (prevalence rate 23.5 % in cases, 40.7 % in controls; p = 0.04). When considering patients with actinic lesions, controls have a higher FRAX score compared with cases. Although sun exposure is recommended for bone health, it represents a risk factor for actinic lesions. The presence of actinic lesions may indicate a lower osteoporotic hip fracture risk. A balance between adequate lifetime sun exposure and protection against its adverse effects is required for each patient, in the context of geographic location.

    Inflammatory fibroid polyps (IFPs) are rarely found in the gastrointestinal tract. The majority of IFPs are sessile-pedunculated or pedunculated polypoid lesions, whereas a polyp presenting like a Borrmann type II lesion is extremely unusual. This report describes the case of a 74-year-old man with a history of intussusception, in whom a preoperative diagnosis of a cecal tumor of the ileocecal valve was made. A laparotomy subsequently revealed a lesion similar to a Borrmann type II tumor located 15 cm above the ileocecal valve, but not at the valve. The lesion was diagnosed as an IFP which had been caused by repeated colostomy irrigation. The aim of the present report is to draw attention to this entity, which should be included in the differential diagnosis of intussusception and small bowel obstruction.

    We describe the case a spinal cord localization of neurological toxoplasmosis in a HIV-positive patient with Burkitt lymphoma, previously treated with chemotherapy and immunotherapy. This complication occurred while patient was in complete remission of lymphoma, with CD4+ T cell count of 270 /ml, undetectable HIV viremia, and despite the trimethoprim/ sulfamethoxazole prophylaxis. Indeed, we hypothesize that in our patient neurologic toxoplasmosis has been fostered more by previous immuno-chemotherapy than by HIV- related immunodeficiency. On the whole, this case suggests that parameters usually employed to predict the risk for opportunistic infections in HIV-positive people might not apply to patients with HIV-related lymphomas.

    Full Text Available Extramedullary plasmacytoma (EMP and solitary bone plasmacytoma (SBP represent a disease continuum through a multistage process of cell differentiation, survival, proliferation, and dissemination, strictly related to multiple myeloma (MM, the second most common hematological malignancy. Herein, we report two cases of recurrent oral plasmacytoma progressed to MM, in which the first clinical sign of a more widespread disease was limited to the mouth. Based on our experience, we recommend a strict workup for the differential diagnosis between EMP, SBP, and MM for patients with oral plasmacytoma, including radiological exam of the skeleton, magnetic resonance imaging (MRI of the bone, and positive emission tomography (FDG-PET. MRI and possibly PET can all be used to more sensitively detect EM plasmacytoma sites.

    Elephantiasis nostras verrucosa is a rare disorder that results from chronic obstructive lymphedema. It is characterized clinically by deforming, nonpitting edema; malodorous hyperkeratosis with generalized lichenification; cobblestoned papules; and verrucous changes, that often result in extreme enlargement of the involved body part. Although elephantiasis nostras verrucosa is striking in clinical appearance, biopsy reveals only moderately abnormal findings: pseudoepitheliomatous hyperplasia with dilated lymphatic spaces in the dermis, accompanied by chronic inflammation and fibroblast proliferation. The term elephantiasis nostras (nostras means "from our region") has traditionally been used to differentiate temperate zone disease from the classic disease process, elephantiasis tropica, which is defined by chronic filarial lymphatic obstruction caused by Wuchereria bancrofti, Wuchereria malayi, or Wuchereria pacifica. We present a case report of elephantiasis nostras verrucosa arising as a result of lymphedema praecox.

The authors sought to obtain insight into the time-sensitive analgesic success and complications of this therapy.Patients and methods: This study was a retrospective case series involving patients with unremitting shoulder pain that had lasted for at least 12 months. Patients were selected if they showed a reduction of at least 50% in pain intensity during the anesthetic phase after SSN block, no additional motor weakness of the shoulder, and pain relief lasting for less than 2 months after separate treatments of the SSN with depot corticosteroids and pulsed radiofrequency. Nine patients were referred to the Arnold Pain Management Center. Of these nine patients, six patients who had significant chronic shoulder pain unresponsive to oral medications and intra-articular injections and who were not considered surgical candidates were selected. These patients were treated with a single radiofrequency lesion of the SSN at 80°C for 60 seconds. The primary outcome was a reduction in pain intensity by 50%, as determined by the numeric rating scale, and duration of this effect. The secondary outcome was improvement in either the passive or the active range of motion (ROM. Patients were also monitored for adverse effects such as weakness or increased pain.Results: The pooled mean numeric rating scale score before the procedure was 7.2 ± 1.2; this fell to 3.0 ± 0.9 at 5–7 weeks post procedure. The duration of pain relief ranged from 3 to 18 months, and all patients underwent at least one additional treatment. The change in baseline ROM improved from an average of 60° ± 28° (flexion and 58° ± 28° (abduction

    Introduction: The purpose of this study was to evaluate MR imaging characteristics with conventional and advanced MR imaging techniques in patients with IIDL. Methods: MR images of the brain in 42 patients (20 male, 22 female) with suspected or known multiple sclerosis (MS) from four institutions were retrospectively analyzed. Lesions were classified into five different subtypes: (1) ring-like lesions; (2) Balo-like lesions; (3) diffuse infiltrating lesions; (4) megacystic lesions; and (5) unclassified lesions. The location, size, margins, and signal intensities on T1WI, T2WI, and diffusion-weighted images (DWI), and the ADC values/ratios for all lesions, as well as the contrast enhancement pattern, and the presence of edema, were recorded. Results: There were 30 ring-like, 10 Balo-like, 3 megacystic-like and 16 diffuse infiltrating-like lesions were detected. Three lesions were categorized as unclassified lesions. Of the 30 ring-like lesions, 23 were hypointense centrally with a hyperintense rim. The mean ADC, measured centrally, was 1.50 ± 0.41 × 10{sup −3} mm{sup 2}/s. The mean ADC in the non-enhancing layers of the Balo-like lesions was 2.29 ± 0.17 × 10{sup −3} mm{sup 2}/s, and the mean ADC in enhancing layers was 1.03 ± 0.30 × 10{sup −3} mm{sup 2}/s. Megacystic lesions had a mean ADC of 2.14 ± 0.26 × 10{sup −3} mm{sup 2}/s. Peripheral strong enhancement with high signal on DWI was present in all diffuse infiltrating lesions. Unclassified lesions showed a mean ADC of 1.43 ± 0.13 mm{sup 2}/s. Conclusion: Restriction of diffusion will be seen in the outer layers of active inflammation/demyelination in Balo-like lesions, in the enhancing part of ring-like lesions, and at the periphery of infiltrative-type lesions.

    Although infectious diseases are the most prevalent cause of fevers of unknown origin (FUO), this diagnosis remains challenging in some pediatric patients. Imaging exams, such as computed tomography (CT) are frequently required during the diagnostic processes. The presence of multiple hypoattenuating scattered images throughout the liver associated with the history of cohabitation with cats should raise the suspicion of the diagnosis of cat-scratch disease (CSD), although the main etiologic agent of liver abscesses in childhood is S taphylococcus aureus . Differential diagnosis by clinical and epidemiological data with Bartonella henselae is often advisable. The authors report the case of a boy aged 2 years and 9 months with 16-day history of daily fever accompanied by intermittent abdominal pain. Physical examination was unremarkable. Abdominal ultrasound performed in the initial work up was unrevealing, but an abdominal CT that was performed afterwards disclosed multiple hypoattenuating hepatic images compatible with the diagnosis of micro abscesses. Initial antibiotic regimen included cefotaxime, metronidazole, and oxacillin. Due to the epidemiology of close contact with kittens, diagnosis of CSD was considered and confirmed by serologic tests. Therefore, the initial antibiotics were replaced by clarithromycin orally for 14 days followed by fever defervescence and clinical improvement. The authors call attention to this uncommon diagnosis in a child presenting with FUO and multiple hepatic images suggestive of micro abscesses.

    We report serial MR imaging of an 11-year-old boy who had a recurrent episode of clinically mild encephalitis/encephalopathy with a reversible splenial lesion. During the first episode, brain lesions were limited to the corpus callosum. However, for the second episode, the lesions were distributed in the corpus callosum and bilateral deep white matter. No abnormality remained in the follow-up MR images obtained after full recovery.

    The clinicopathologic features of nine cases of papillary proliferation of the endometrium devoid of malignant nuclear features were studied. The patients ranged in age from 33 to 71 years (median 57 years). All were postmenopausal, except the youngest. The most common symptom was postmenopausal bleeding. Two patients were receiving hormonal replacement therapy and two were taking megestrol acetate. Two lesions were incidental findings in a hysterectomy specimen. Seven were diagnosed in endometrial biopsy or curettage specimens. In six cases (67%) the lesion involved an endometrial polyp. In all cases the papillae had fibrovascular stromal cores and variable degrees of branching. Two architectural patterns were found. A simple papillary pattern with involvement of only a few glands and little epithelial proliferation occurred in five cases, including three that were entirely intracystic. A complex papillary pattern with more extensive involvement of endometrial glands, a greater degree of branching of the papillae, and cellular tufting occurred in four cases. One or more metaplastic epithelial changes occurred in all cases, including endocervical-type mucinous metaplasia in nine cases (90%), eosinophilic cell change in eight (89%), ciliated cell change in seven (70%), focal squamous metaplasia in two cases (22%), and hobnail cell change in two (22%). Mitotic figures were found in three cases. In four lesions (44%), all with a complex papillary pattern, the proliferating cells had mild nuclear atypia. Three of these patients underwent hysterectomy within 5 months. Simple nonpapillary hyperplasia and two endometrial polyps were found in one patient, complex nonpapillary hyperplasia in one, and atrophic endometrium in the other. Two patients had additional endometrial samplings within 4 months that contained small residual simple papillary lesions. One of these had another biopsy at 16 months that showed only atrophy. One patient had no subsequent diagnostic or

    Background: The hook sign (HS) has recently been introduced as a new descriptor for differential diagnosis in magnetic resonance mammography (MRM). Purpose: To analyze the diagnostic value of HS in a large collection of 1084 cases. Material and Methods: This study was approved by the local ethics committee, and 1084 consecutive lesions (no manipulations of the breast up to 12 months before MRM) with histological verification after MRM were included. HS was analyzed according to standard study protocols and was rated positive if a hook-like spiculated dendrite connecting a lesion with the pectoral muscle could be visualized. Examinations were rated by experienced observers (>500 examinations). Prevalence of HS was correlated with histological diagnosis, grading, and size (chi-square test). Diagnostic accuracy was assessed using sensitivity, specificity, positive likelihood ratio (LR+), and diagnostic odds ratio (DOR). Results: HS was significantly associated with malignancy (P 20 mm presented with HS significantly more often than those <20 mm (P < 0.001). HS was characteristic of invasive cancers and rare in preinvasive malignomas (P < 0.001). Prevalence of HS did not differ between invasive lobular and ductal carcinomas (n.s.). There was no correlation between HS and the grading of invasive carcinomas. Conclusion: In 1084 lesions, the hook sign was a specific descriptor for differentiation of benign and malignant lesions in MRM, with high evidence for prediction of malignancy, particularly in the case of advanced lesions and invasive carcinomas

    Full Text Available Abstract Introduction Patients with clinically mild encephalitis/encephalopathy with a reversible splenial lesion present with relatively mild central nervous system disturbances. Although the exact etiology of the condition remains poorly understood, it is thought to be associated with infective agents. We present a case of a patient with mild encephalitis/encephalopathy with a reversible splenial lesion, who had the unusual feature of acute urinary retention. Case presentation A 23-year-old Japanese woman developed mild confusion, gait ataxia, and urinary retention seven days after onset of fever and headache. Magnetic resonance imaging demonstrated T2 prolongation in the splenium of the corpus callosum and bilateral cerebral white matter. These magnetic resonance imaging abnormalities disappeared two weeks later, and all of the symptoms resolved completely within four weeks. Except for the presence of acute urinary retention (due to underactive detrusor without hyper-reflexia, the clinical and radiologic features of our patient were consistent with those of previously reported patients with mild encephalitis/encephalopathy with a reversible splenial lesion. To the best of our knowledge, this is the first report of acute urinary retention recognized in a patient with mild encephalitis/encephalopathy with a reversible splenial lesion. Conclusion Our findings suggest that mild encephalitis/encephalopathy with a reversible splenial lesion can be associated with impaired bladder function and indicate that acute urinary retention in this benign disorder should be treated immediately to avoid bladder injury.

    2001-08-01

    The authors report the case of a 37-year-old woman who presented with amenorrhea and an increased level of serum prolactin. Magnetic resonance images of the pituitary revealed a lesion with characteristics consistent with those of a microadenoma. Transsphenoidal exploration was performed, but a prolactinoma was not found. After endocrinological review, the patient's hyperprolactinemia was found to be caused by the presence of macroprolactin and her amenorrhea was due to intense exercise and low body weight. Macroprolactin is an isoform of prolactin that is variably reactive in assays for prolactin, but displays minimum bioactivity in vivo. Patients with macroprolactin are mostly asymptomatic. This phenomenon may cause elevated prolactin values, which the authors view as apparent hyperprolactinemia. The presence of macroprolactin is an underrecognized problem, occurring in as many as 15 to 20% of patients with elevated prolactin values and often leading to unnecessary, expensive diagnostic procedures and inappropriate treatment. The presence of macroprolactin should always be suspected when the patient's clinical history or clinical or radiological data are incompatible with the prolactin value. Physicians dealing with diagnosis and treatment of hyperprolactinemia (general practitioners, gynecologists, neurosurgeons, endocrinologists, and biochemists) should be aware of the potentially misleading nature of macroprolactin.

    An osteolytic lesion with a small central area of mineralization and sclerotic borders was discovered incidentally in the clivus on the cone-beam computed tomography (CBCT) of a 27-year-old male patient. This benign appearance indicated a primary differential diagnosis of non-aggressive lesions such as fibro-osseous lesions and arrested pneumatization. Further, on magnetic resonance imaging (MRI), the lesion showed a homogenously low T1 signal intensity with mild internal enhancement after post-gadolinium and a heterogeneous T2 signal intensity. These signal characteristics might be attributed to the fibrous tissues, chondroid matrix, calcific material, or cystic component of the lesion; thus, chondroblastoma and chondromyxoid fibroma were added to the differential diagnosis. Although this report was limited by the lack of final diagnosis and the patient lost to follow-up, the incidental skull base finding would be important for interpreting the entire volume of CBCT by a qualified oral and maxillofacial radiologist.

    The Morel-Lavallée lesion is a collection of serous fluid that develops after closed degloving injuries and after surgical procedures particularly in the pelvis and abdomen. It is a persistent seroma and is usually resistant to conservative methods of treatment such as percutaneous drainage and compression. Various methods of curative treatment have been reported in the literature, such as application of fibrin sealant, doxycycline, or alcohol sclerodhesis. We present a case of a huge recurrent Morel-Lavallée lesion in the lower back and buttock region that was treated with quilting sutures, fibrin sealant, and compression, with a review of the literature. © The Author(s) 2014.

  13. SU-F-T-637: Single-Isocenter Versus Multiple-Isocenter VMAT SRS for Unusual Multiple Metastasis Case with Two Widely Separated Lesions

    2016-06-15

    Purpose: Single-isocenter (SI) volumetric modulated arc therapy has been shown to be an effective and efficient approach to multiple metastasis radiosurgery. However, certain extreme cases raise the question of whether multiple-isocenter (MI) approaches can still generate superior plans. In this study, we ask this question with respect to a clinical case with two very widely separated lesions. Methods: A patient with two widely separated (d = 12cm) tumors was treated with SI-VMAT SRS using 10MV flattening filter free (FFF) beam with high-definition multi-leaf collimator (HD-MLC, 2.5/5mm) in two non-coplanar arcs using concentric rings to enforce steep gradient. Because of lesion positioning with respect to collimator angle selection, lesions were treated by 5mm leaves. We re-planned the case with a congruent arc arrangement but separate isocenter for each lesion. In this manner, lesions were treated by 2.5mm leaves. Conformity index (CI), V50%, and mean brain dose were compared. Results: Neither conformity (CI-SI = 1.12, CI-MI = 1.08) nor V50% (V50%-SI =8.82cc, V50%-MI =8.81cc) were improved by utilizing a separate isocenter for each lesion. Mean brain dose was slightly reduced (dmean-SI = 118.4 cGy, dmean-MI = 88.7 cGy) by using multiple isocenters. Conclusion: For this case with a lesion at the apex of the brain and another distantly located at the base of skull, employing a separate isocenter for each target did not meaningfully improve plan quality. Single-isocenter VMAT has been shown feasible and equivalent to multiple-isocenter VMAT for multiple metastasis cases in general. In this extreme case, single- and multiple- isocenter VMAT were also equivalent. If rotational setup errors are appropriately corrected, the increased delivery efficiency of the single-isocenter approach renders it preferable to the multiple isocenter approach.

    Full Text Available Radicular cyst (RC is the most common odontogenic cyst of inflammatory origin affecting the jaws; involves the roots of the carious or traumatic non-vital tooth. Different therapeutic modalities, such as nonsurgical endodontic therapy or surgical enucleation with primary closure, decompression etc., were proposed for the management of such lesions. Presenting a case of a 28-year-old otherwise healthy male patient who reported with pain and swelling with respect to tooth #41, 31. Diagnosis of infected RC at a rare location was established on the basis of clinical, radiographical and fine needle aspiration cytological examination. Looking after the clinical characteristics, origin, extension, size of cystic lesion and patient cooperation; nonsurgical endodontic therapy utilizing Bhasker's hypothesis was opted. One year post-operative result suggested that nonsurgical endodontic therapy along with minimally invasive treatment utilizing Bhasker's hypothesis is an effective tool to transform infected radicular cystic lesion to healthy periapical periodontal tissue.

    Anatomically the pulp and periodontium are connected through apical foramen, and the lateral, accessory, and furcal canals. Diseases of one tissue may affect the other. In the present case report with two cases, a primary periodontal lesion with secondary endodontic involvement is described. In both cases, root canal treatment was done followed by periodontal therapy with the use of platelet-rich fibrin (PRF) as the regenerative material of choice. PRF has been a breakthrough in the stimulation and acceleration of tissue healing. It is used to achieve faster healing of the intrabony defects. Absence of an intraradicular lesion, pain, and swelling, along with tooth stability and adequate radiographic bone fill at 9 months of follow-up indicated a successful outcome. PMID:25425831

    We report on a 30-year-old man with neuro-Behcet's disease. His main neurologic symptoms and signs included headache, alternating hemiparesis, dysarthria, and truncal ataxia. Lumbar puncture demonstrated an elevated pressure, pleocytosis, and an increased protein concentration. Intravenous betamethasone produced a rapid and sustained improvement, without recurrence for two years. Widely scattered foci of small, low-density lesions were disclosed in the midbrain and the pons on a cranial CT scan with 2.5 mm thin-cut slices to enable us to focus on the brainstem. Such CT lesions are consistent with the neuropathological features of this illness, which shows a tendency for brainstem lesions to predominate; these lesions probably represent necrotic areas secondary to vasculitis. Brainstem CT studies with thin-cut slices may be an important diagnostic aid in patients suspected of having neuro-Behcet's disease. (author)

    Full Text Available This study describes the treatment of an immature permanent tooth with periapical lesion which was treated with regenerative approach using platelet rich plasma (PRP. The root canal of immature human permanent tooth with periapical lesion was gently debrided of necrotic tissue and disinfected with 2.5% NaOCl, and then medicated with triple antibiotic paste comprised of ciprofloxacin, metronidazole, and tetracycline. When the tooth was asymptomatic, PRP and mineral trioxide aggregate (MTA were placed into the root canal. Six months after PRP treatment, radiographical examination revealed resolution of the radiolucency and progressive thickening of the root wall and apical closure. Our findings suggest that PRP can be used for the treatment of immature permanent teeth with periapical lesion, as part of a regenerative endodontic treatment procedure.

    Today, subject's medical data in controlled clinical trials is captured digitally in electronic case report forms (eCRFs). However, eCRFs only insufficiently support integration of subject's image data, although medical imaging is looming large in studies today. For bed-side image integration, we present a mobile application (App) that utilizes the smartphone-integrated camera. To ensure high image quality with this inexpensive consumer hardware, color reference cards are placed in the camera's field of view next to the lesion. The cards are used for automatic calibration of geometry, color, and contrast. In addition, a personalized code is read from the cards that allows subject identification. For data integration, the App is connected to an communication and image analysis server that also holds the code-study-subject relation. In a second system interconnection, web services are used to connect the smartphone with OpenClinica, an open-source, Food and Drug Administration (FDA)-approved electronic data capture (EDC) system in clinical trials. Once the photographs have been securely stored on the server, they are released automatically from the mobile device. The workflow of the system is demonstrated by an ongoing clinical trial, in which photographic documentation is frequently performed to measure the effect of wound incision management systems. All 205 images, which have been collected in the study so far, have been correctly identified and successfully integrated into the corresponding subject's eCRF. Using this system, manual steps for the study personnel are reduced, and, therefore, errors, latency and costs decreased. Our approach also increases data security and privacy.

    Acute and late radiation-induced injury on skin and subcutaneous tissues are associated with substantial morbidity in radiation therapy, interventional procedures and also are of concern in the context of nuclear or radiological accidents. Pathogenesis is initiated by depletion of acutely responding epithelial tissues and damage to vascular endothelial micro-vessels. Efforts for medical management of severe radiation-induced lesions have been made. Nevertheless, the development of strategies to promote wound healing, including stem cell therapy, is required. From 1997 to 2014, over 248 patients were referred to the Radio-pathology Committee of Hospital de Quemados del Gobierno de la Ciudad de Buenos Aires (Burns Hospital) for the diagnosis and therapy of radiation-induced localized lesions. As part of the strategies for the management of severe cases, there is an ongoing research and development protocol on 'Translational Clinical Trial phases I/II to evaluate the safety and efficacy of adult mesenchymal stem cells from bone marrow for the treatment of large burns and radiological lesions'. The object of this work was to describe the actions carried out by the Radio-pathology Committee of the Burns Hospital in a chronic case with more than 30 years of evolution without positive response to conventional treatments. The approach involved the evaluation of the tissular compromise of the lesion, the prognosis and the personalized treatment, including regenerative therapy. (authors)

    Charcot's spine is a long-term complication of spinal cord injury. The lesion is often localized at the caudal end of long fusion constructs and distal to the level of paraplegia. However, cases are rare and the literature relevant to the management of Charcot's arthropathy is limited. This paper reviews the clinical features, diagnosis, and surgical management of post-traumatic spinal neuroarthropathy in the current literature. We present a rare case of adjacent level Charcot's lesion of the lumbar spine in a paraplegic patient, primarily treated for traumatic spinal cord lesion 39 years before current surgery. We have performed end-to-end apposition of bone after 3 column resection of the lesion, 3D correction of the deformity, and posterior instrumentation using a four-rod construct. Although the natural course of the disease remains unclear, surgery is always favorable and remains the primary treatment modality. Posterior long-segment spinal fusion with a four-rod construct is the mainstay of treatment to prevent further morbidity. Our technique eliminated the need for more extensive anterior surgery while preserving distal motion. © The Authors, published by EDP Sciences, 2017.

    Although large lesions of the limbs can easily be biopsied without image guidance, lesions in the spine, paraspinal area and pelvis are difficult to target, and benefit from CT guidance to improve the accuracy of targeting the lesion for biopsy purposes. A prospective study of CT-guided core needle biopsies for deep-seated musculoskeletal lesions was conducted at a referral cancer institute over a 4-year period with the aim of assessing the safety and efficacy of the procedure. From January 2000 to December 2003, 136 consecutive CT-guided biopsy sessions were undertaken for musculoskeletal lesions in 128 patients comprising 73 males and 55 females. The following data was recorded in all patients: demographic data, suspected clinicoradiological diagnosis, data related to core biopsy session (date, site, approach, total time required in minutes, number of cores, surgeon satisfaction with adequacy of cores), patient discomfort, complications, histopathology report and number of further sessions if material obtained during the first biopsy session was not confirmatory. The sample obtained during the biopsy session was considered inconclusive if, in the opinion of the pathologist, inadequate or non-representative tissue had been obtained. The diagnosis was considered inaccurate if the final histopathological diagnosis did not match with the biopsy diagnosis, or if subsequent clinicoradiological evaluation at follow up did not correlate with the biopsy diagnosis in those patients who were treated with modalities other than surgery. In 121 patients, a single session was sufficient to obtain representative material, whilst for six patients two sessions, and for one patient three sessions were necessary. The time taken for biopsy, including the pre-biopsy CT examination time, varied from 15 min to 60 min (median 30 min). For 110 bony lesions 116 sessions were required, and for 18 soft-tissue lesions 20 sessions were required. 108 biopsy sessions yielded a diagnosis, whilst

    Full Text Available Abstract Background Left-sided lesions (LSLs account for an important fraction of severe congenital cardiovascular malformations (CVMs. The genetic contributions to LSLs are complex, and the mutations that cause these malformations span several diverse biological signaling pathways: TGFB, NOTCH, SHH, and more. Here, we use whole exome sequence data generated in 342 LSL cases to identify likely damaging variants in putative candidate CVM genes. Methods Using a series of bioinformatics filters, we focused on genes harboring population-rare, putative loss-of-function (LOF, and predicted damaging variants in 1760 CVM candidate genes constructed a priori from the literature and model organism databases. Gene variants that were not observed in a comparably sequenced control dataset of 5492 samples without severe CVM were then subjected to targeted validation in cases and parents. Whole exome sequencing data from 4593 individuals referred for clinical sequencing were used to bolster evidence for the role of candidate genes in CVMs and LSLs. Results Our analyses revealed 28 candidate variants in 27 genes, including 17 genes not previously associated with a human CVM disorder, and revealed diverse patterns of inheritance among LOF carriers, including 9 confirmed de novo variants in both novel and newly described human CVM candidate genes (ACVR1, JARID2, NR2F2, PLRG1, SMURF1 as well as established syndromic CVM genes (KMT2D, NF1, TBX20, ZEB2. We also identified two genes (DNAH5, OFD1 with evidence of recessive and hemizygous inheritance patterns, respectively. Within our clinical cohort, we also observed heterozygous LOF variants in JARID2 and SMAD1 in individuals with cardiac phenotypes, and collectively, carriers of LOF variants in our candidate genes had a four times higher odds of having CVM (odds ratio = 4.0, 95% confidence interval 2.5–6.5. Conclusions Our analytical strategy highlights the utility of bioinformatic resources, including human

    A case of hemifacial hyperplasia that presented with muscular, skeletal, and dental hyperplasia along with lipomatous infiltration was described. Advanced imaging was useful in identifying the lipomatous infiltration present in the lesion, which raises the possibility of lipomatosis having a diverse presentation in hemifacial hyperplasia. As there was a scarcity of related literature in the field of dentomaxillofacial radiology, this report would make us familiar with its computed tomographic and magnetic resonance image findings.

    Magnetic resonance (MR) imaging may provide some information as to the extent and tissue characteristics of a cancerous mass, but the imaging features of lesions in the floor of the mouth have not been sufficiently clarified. MR imaging features of tumescent lesions in this region were characterized, and the differential diagnoses are discussed. MR images of 12 patients with tumescent lesions in the floor of the mouth (three patients with squamous cell carcinoma, two with adenoid cystic carcinoma, one with hemangioma, one with schwannoma, one with lipoma, and four with ranula) were reviewed. The literature on the imaging features of tumescent disease in the floor of the mouth was searched using the Medline database. Six types of tumescent lesions in the floor of the mouth are presented. The differential diagnosis through a review of the references is discussed. Malignant tumors were demonstrated as ill-defined masses. MR images were good at showing the internal structures, such as fluid, hemorrhage, fat, nerves, calculus (phlebolith), cholesterol, and keratin, as different signal intensities. Therefore, MR images gave clues for the differential diagnosis. MR images presented the distinctive features or the extent of the lesions and were therefore considered useful for a more accurate diagnosis prior to treatment. (author)

    Any pathological damage occurring in a bone will produce either an osteolytic or osteosclerotic lesion which can be seen in the macroscopic specimen as well as in the roentgenogram. Various bone lesions may lead to local destructions of the bone. An osteoma or osteoplastic osteosarcoma produces an osteosclerotic lesion showing a dense mass in the roentgenogram; a chondroblastoma or an osteoclastoma, on the other hand, induces an osteolytic focal lesion. This paper presents examples of different osteolytic lesions of the humerus. An osteolytic lesion seen in the roentgenogram may be either produced by an underlying non-ossifying fibroma of the bone, by fibrous dysplasia, osteomyelitis or Ewing's sarcoma. Differential diagnostic considerations based on the radiological picture include eosinophilic bone granuloma, juvenile or aneurysmal bone cyst, multiple myeloma or bone metastases. Serious differential diagnostic problems may be involved in case of osteolytic lesions occurring in the humerus. Cases of this type involving complications have been reported and include the presence of an teleangiectatic osteosarcoma as well as that of a hemangiosarcoma of the bone.

    Significant bleeding may occur following endobronchial forceps biopsy or brushing of necrotic or hypervascular tumors in the airways. In some cases, methods such as endobronchial instillation of iced saline lavage and epinephrine may fail to control bleeding. The present study evaluated the efficacy and safety of a new bronchoscopic technique using intratumoral injection of tranexamic acid (IIT) for control of bleeding during forceps biopsy in patients with endobronchial tumors with a high risk of bleeding. The study was a prospective case series carried out in a single center. Bronchoscopic IIT was performed in those patients who had endoscopically visible tumoral lesions with persistent active bleeding following the first attempt at bronchoscopic sampling. Tranexamic acid (TEA) was injected through a 22-gauge Wang cytology needle into the lesion in nominal doses of 250–500 mg. After 2–3 minutes, multiple forceps biopsy specimens were obtained from the lesion. Of the 57 consecutive patients included in the study, 20 patients (35.1%) underwent bronchoscopic IIT. The first attempt in 18 patients was endobronchial forceps biopsy (EBB), and because of a high risk of bleeding, the first attempt for the remaining two patients, who were on continuous dual antiplatelet therapy (aspirin and clopidogrel), employed endobronchial needle aspiration (EBNA) as a precautionary measure. Following IIT, subsequent specimens were obtained using EBB in all patients. Multiple forceps biopsy specimens (3–10) were obtained from the lesions (8 necrotic and 12 hypervascular) without incurring active bleeding. The following histopathologic diagnoses were made: squamous cell carcinoma (n = 14), adenocarcinoma (n = 2), small-cell lung cancer (n = 3), and malignant mesenchymal tumor (n = 1). No side effects of TEA were observed. Bronchoscopic IIT is a useful and safe technique for controlling significant bleeding from a forceps biopsy procedure and can be considered as a pre

    Morel-Lavallée lesions are posttraumatic hemolymphatic collections caused by disruption of the interfascial planes between the subcutaneous soft tissue and muscle. Severe peripelvic Morel-Lavallée lesions have rarely been reported in the literature. By contrast, a number of cases of gluteal muscle necrosis following transcatheter angiographic embolization for pelvic fracture have been reported. Each entity can result in severe infection and sepsis, and the mortality rate in such cases is quite high. However, to date, no previous reports have described a case in which these life-threatening entities occurred simultaneously. A 32-year-old Asian man simultaneously developed severe peripelvic Morel-Lavallée lesions and gluteal muscle necrosis with sepsis following transcatheter angiographic embolization after an unstable pelvic fracture. Extremely large skin and soft tissue defects, which were untreatable with any commonly used flaps, were generated after repeated debridement. In addition, a deep-bone infection was suspected in his left fractured iliac bone, while motor function was almost completely lost in his left leg, possibly as a sequela of transcatheter angiographic embolization. As a result of his condition, a left hemipelvectomy was unavoidable. A pedicled fillet flap from his sacrificed left limb was used for the treatment of the defects and to provide a durable base for a prosthesis. Our patient survived and returned to his previous job 24 months after the surgery wearing a prosthetic left leg. As illustrated by the present case, severe peripelvic Morel-Lavallée lesions and gluteal muscle necrosis following transcatheter angiographic embolization can occur simultaneously after unstable pelvic fractures. Physicians should recognize that these entities can result in life-threatening sepsis and, therefore, should attempt to detect them as early as possible. When hemipelvectomy is unavoidable, a pedicled upper and lower leg in-continuity fillet flap may

    Clinically mild encephalitis/encephalopathy with a reversible splenial lesion (MERS) is a mild encephalopathy caused by various pathological processes, but encephalopathy due to bacteria is rare. We report the case of a 45-year-old Japanese woman who on receiving chemotherapy for advanced breast cancer developed an altered mental status and dysarthria soon after fever from infection of a subcutaneous implantable port. Staphylococcus aureus was detected in her blood cultures. Magnetic resonance imaging (MRI) revealed an ovoid lesion in the central portion of the splenium of the corpus callosum (SCC). Although hypotension was not observed, we diagnosed probable toxic shock syndrome (TSS) based on fever (temperature: >38.9 °C), altered mental status, erythema, desquamation, thrombocytopenia, liver dysfunction, and creatine phosphokinase elevation. We administered antimicrobial therapy and her neurological symptoms improved gradually. The lesion in the SCC completely disappeared on MRI 7 days after disease onset. We diagnosed this case as MERS caused by S. aureus bacteremia with TSS. This is the first report of such a case, and we suggest that when a TSS patient presents with neurological symptoms, the possibility of MERS should be considered.

    Pleomorphic malignant fibrous histiocytoma (MFH), also known as undifferentiated high-grade pleomorphic sarcoma according to the latest World Health Organization classification, is a diagnosis of exclusion and extremely rare in adult scrotal/paratesticular region. Clinical presentation of scrotal/paratesticular pleomorphic MFH is usually a painless and gradual scrotal swelling. We report a case of scrotal MFH in a 63-year-old man who presented as Fournier gangrene after 10-month painful scrotal swelling and multiple procedures. The specimen of emergent debridement was submitted for pathologic and bacteriologic examination. Microscopically, the lesion had marked architectural and cytologic pleomorphism. The neoplastic cells were positive for vimentin, but negative for all lineage-specific markers. Fluorescence in-situ hybridization showed an aneuploid karyotype and negative results for lipomatous tumor abnormalities. Bacterial cultures of the specimen showed extensive growth of virulent polymicrobes. The diagnosis of scrotal/paratesticular pleomorphic MFH with concurrent Fournier gangrene was made. Thoracic computed tomography scan showed bilateral multiple pulmonary nodules. The patient died 1 month later.

We report an unusual case of granulomatous lung disease with uncommon characteristics, which developed following Epstein-Barr-virus-induced mononucleosis and new-onset systemic lupus erythematosus. We aim to highlight a diagnostic approach for the condition and to raise awareness of the possibility of it being related to the immunological reaction caused by Epstein-Barr virus infection. Case presentation A 36-year-old Japanese man, who had been diagnosed with Epstein-Barr-virus-induced infectious mononucleosis, new-onset systemic lupus erythematosus, and secondary Sjögren’s syndrome three weeks previously, presented to our facility with fever and diffuse pulmonary infiltrates. A computed tomography scan of the chest revealed multiple small nodules in both lungs. Fiberoptic bronchoscopy with bronchoalveolar lavage revealed lymphocytosis with predominance of T lymphocytes. A histological examination of a lung biopsy taken during video-assisted thoracic surgery showed randomly distributed tiny granulomatous lesions with infiltration of eosinophils. The differential diagnoses included hypersensitivity pneumonitis, sarcoidosis, and pulmonary involvement of Crohn’s disease, systemic lupus erythematosus, and Sjögren’s syndrome, but the clinical and pathological findings were not consistent with any of these. Our patient’s condition did not improve; therefore, prednisolone therapy was started because of the possibility of specific immunological reactions associated with Epstein-Barr virus infection. After steroid treatment, our patient showed radiological and clinical improvement. Conclusions To the best of our knowledge, this is the first case of a patient developing randomly distributed multiple granulomatous lung lesions with eosinophilic infiltrates after Epstein-Barr virus infection and systemic

    Meningitis is a common central nervous system (CNS) complication of the mumps, a viral infection, but encephalitis and meningoencephalitis are less common in mumps. We describe magnetic resonance imaging findings of acute mumps meningoencephalitis in a 32-year-old male who showed bilateral hippocampal lesions without preceding parotitis. Although it is rare, hippocampal involvement should be considered a CNS complication of mumps infection.

    For A long time the solitary pulmonary nodule has remained a difficult problem to solve and has attracted a great deal of attension in recent years. Circumscribed coin lesions of the lung were generally peripheral in location with respect to the pulmonary hilus. Because of this, important clinical problem in management and diagnosis arise. Such a lesion is discovered through roentgenologic examination. So the roentgenologists is the first be in a position to offer advise. This presentation is an attempt to correlate a useful diagnosis with roentgenologic findings of pulmonary coin lesion which enables us to get differential diagnosis of benign and malignant lesion. Histologically proven 120 cases of the pulmonary coin lesion during the period of 8 years were reviewed through plain film, tomogram, bronchoscopy, variable laboratory findings, and clinical history. The results are as follows: 1. Male to female sex ratio was 3 : 1. In age distribution, most of the malignant pulmonary coin lesion appeared in 6th decade (39%) and 5th decade (27%). In benign lesion, the most cases were in 3 rd decade. 2. Pathological cell type are as follows: Primary bronchogenic cancer 43.3%, tuberculoma 25.8%, inflammatory lesion 17.5%, benign tumor 10%, and bronchial adenoma, harmartoma, A.V. malformation, mesothelioma, are 1 case respectively. As a result benign and malignant lesion showed equal distribution (49.1% : 50.3%). 3. In symptom analysis ; cough is the most common (43.5%) symptom in malignant lesion, next follows hemoptysis (20.9%) and chest pain (14.5%). In benign lesion, most of the patient (32.7%) did not complain any symptom. 4. In malignant lesion, the most common nodular size was 4 cm (32.3%), and in benign lesion 2 cm sized coin was most common (39.3%). 5. In general, margin of nodule was very sharp and well demarcated in benign lesion (83.3%), and in malignant lesion that was less demarcated and poorly defined. 6. Most case of calcification (82.7%) was seen in benign

    Full Text Available Stem cells are the pluripotent cells that have the capacity to differentiate into other specialized cells. Recently, many experiments have been conducted to study the potentiality of stem cells in the tissue regeneration. We report two cases treated utilizing stem cells from human exfoliated deciduous teeth (SHED in the management of periapical lesions in permanent teeth. Two normal human deciduous teeth from children, 7‒8 years of age, were collected to isolate stem cells. Two patients, one with periapical pathology alone and the other with periapical lesion along with an open apex in young permanent teeth, were selected for the study. After initial debridement of the root canals, homing of SHED was carried out and the access cavity was sealed using glass-ionomer cement. Clinical examination after 7 days, 30 days, 90 days, 180 days and 365 days revealed no symptoms. Closure of open apex and periapical tissue healing were observed radiographically at one-month review and maintained until 365-day review. Positive response to electric pulp testing was recorded for the treated teeth from the 3- to 12-month follow-ups. The treated cases demonstrated complete resolution of periapical radiolucency in a span of 30 days, which was faster than the conventional methods. SHED could be considred effective in treating the periapical lesions and open apex in permanent teeth.

    Cutaneous human papillomaviruses (HPVs) increase the risk of non-melanoma skin cancer in sun-exposed skin. We examined the role of beta-HPV in the development of male external genital lesions (EGLs), a sun-unexposed site. In this nested case-control study (67 men with pathologically-confirmed EGLs and 134 controls), exfoliated cells collected from the surface of lesions and normal genital skin 0, 6, and 12 months preceding EGL development were tested for beta-HPV DNA using a type-specific multiplex genotyping assay. Beta-HPV prevalence was estimated and conditional logistic regression was used to evaluate the association with condyloma, the most common EGL. While beta-HPV prevalence among controls remained stable, the prevalence among cases was lowest on the surface of lesion. Detecting beta-HPV on the normal genital skin was not associated with the presence or development of condyloma. Cutaneous beta-HPV does not appear to be contributing to pathogenesis in male genital skin. Copyright © 2016. Published by Elsevier Inc.

    An 11-year-old girl presented with a 2-month history of progressively worsening cough, daily fevers, and weight loss. A chest radiograph revealed multiple cystic cavitary lung lesions. An extensive infectious work-up was negative. Chest CT verified multiple cavitary lung lesions bilaterally, and [F-18]2-fluoro-2-deoxy-D-glucose ({sup 18}F-FDG) positron emission tomography with CT (PET/CT) showed increased uptake in the lung lesions as well as regional lymph nodes. Subsequent biopsy of an involved lymph node confirmed classical Hodgkin lymphoma, nodular sclerosis type. This case represents an unusual presentation for a child with Hodgkin lymphoma and demonstrates a role for {sup 18}F-FDG PET/CT in evaluating a child with cavitary lung lesions. (orig.)

    Radiographic lesions related to root-filled teeth may persist for long periods after treatment and are considered to indicate failure of initial treatment. Persistent lesions are found in a proportion of cases, but information on lesion progression is lacking. This study examined the incidence of lesion improvement, remaining unchanged, and deterioration among persistent lesions in a group of patients recruited from a university-based clinic and identified potential predictors for lesion progression. Patients of a university clinic with persistent endodontic lesions at least 4 years since treatment and with original treatment radiographs available were recruited with informed consent. Data were obtained by interview and from dental records and clinical and radiographic examinations. Univariate and multivariate statistical analyses were carried out by using SPSS (version 19). One hundred fifty-one persistent lesions were identified in 114 patients. A majority of the lesions (107, 70.9%) received treatment between 4 and 5 years prior. Eighty-six lesions (57.0%) improved, 18 (11.9%) remained unchanged, and 47 (31.1%) deteriorated since treatment. Potential predictors for lesions that did not improve included recall lesion size, pain on biting at recall examination, history of a postobturation flare-up, and a non-ideal root-filling length (P < .05). Lesions that had persisted for a longer period appeared less likely to be improving (relative risk, 1.038; 95% confidence interval, 1.000-1.077). A specific time interval alone should not be used to conclude that a lesion will not resolve without intervention. This study identified several clinical factors that are associated with deteriorating persistent lesions, which should aid in identifying lesions that require further intervention.

    Absence of periapical healing after orthograde retreatment using an apical plug with mineral trioxide aggregate (MTA) can require surgical intervention. A patient with a root-filled maxillary central incisor with chronic apical periodontitis and sinus tract was referred for endodontic retreatment. Excessive apical enlargement was verified, indicating an MTA apical plug placement; however, an unintentional extrusion of MTA occurred during this step. The root canal was filled with gutta-percha and sealer, and periodic recalls were scheduled. The sinus tract was observed after six months and the lesion remained unaltered, although the extruded MTA had resorbed; therefore, an apicoectomy and retrograde root-end filling with MTA were performed. Absence of sinus tract, normal clinical aspect, and complete repair of the lesion were observed at the two-year follow-up.

    A 59-year-old woman who had Weber-Christian disease associated with typical histological findings such as panniculitis was reported. The patient had painful subcutaneous nodules as the first symptom. She had diabetes mellitus and rheumatoid arthritis, which are reported to be rare complications of this disease. Abdominal ultrasonography and CT scanning revealed various sized cystic lesions and masses in the tail of pancreas. These findings have not yet been reported and seems to be rare in this disease.

    A 36-year-old woman with a history of cerebral meningitis had various neuropsychological disorders, such as Gerstmann's syndrome, developmental apraxia and agnosia and difficulty in reading, in addition to moderate mental retardation and epileptoid. Cranial CT showed bilateral low-density areas with temporo-parieto-occipital extension. It seems that these lesions result from meningitis and are responsible for the occurrence of neuropsychological disorders. (Namekawa, K.)

    Full Text Available Abstract Background Ankle sprains are common in sports and can sometimes result in a persistent pain condition. Purpose Primarily to evaluate clinical symptoms, signs, diagnostics and outcomes of surgery for symptomatic chondral injuries of the talo crural joint in athletes. Secondly, in applicable cases, to evaluate the accuracy of MRI in detecting these injuries. Type of study: Prospective consecutive series. Methods Over around 4 years we studied 61 consecutive athletes with symptomatic chondral lesions to the talocrural joint causing persistent exertion ankle pain. Results 43% were professional full time athletes and 67% were semi-professional, elite or amateur athletes, main sports being soccer (49% and rugby (14%. The main subjective complaint was exertion ankle pain (93%. Effusion (75% and joint line tenderness on palpation (92% were the most common clinical findings. The duration from injury to arthroscopy for 58/61 cases was 7 months (5.7–7.9. 3/61 cases were referred within 3 weeks from injury. There were in total 75 cartilage lesions. Of these, 52 were located on the Talus dome, 17 on the medial malleolus and 6 on the Tibia plafond. Of the Talus dome injuries 18 were anteromedial, 14 anterolateral, 9 posteromedial, 3 posterolateral and 8 affecting mid talus. 50% were grade 4 lesions, 13.3% grade 3, 16.7% grade 2 and 20% grade 1. MRI had been performed pre operatively in 26/61 (39% and 59% of these had been interpreted as normal. Detection rate of cartilage lesions was only 19%, but subchondral oedema was present in 55%. At clinical follow up average 24 months after surgery (10–48 months, 73% were playing at pre-injury level. The average return to that level of sports after surgery was 16 weeks (3–32 weeks. However 43% still suffered minor symptoms. Conclusion Arthroscopy should be considered early when an athlete presents with exertion ankle pain, effusion and joint line tenderness on palpation after a previous sprain

    Using a microcomputer, the locus and extent of the lesions, as demonstrated by computed tomography for 127 cases with various types of aphasia were superimposed onto standardized marices. The relationship between the foci of the lesions and the types of aphasia was investigated. Broca aphasics (n=39) : Since the accumulated site of the lesions highly involved the deep structures of the lower part of the precentral gyrus as well as the insula and lenticular nucleus, only 60% of the Broca aphasics had lesions on these areas. This finding has proved to have little localizing value. Wernicke aphasics (n=23) : The size of the lesion was significantly smaller than Broca's aphasia. At least 70% of the patients had the superior temporal lesions involving Wernicke's area and subcortical lesions of the superior and middle temporal gyri. Amnestic aphasics (n=18) : The size of the lesion was smaller than any other types. While there was some concentration of the lesions (maximum 40%) in the area of the subcortical region of the anterior temporal gyrus adjacent to Wernicke's area and the lenticular nucleus, the lesions were distributed throughout the left hemisphere. Amnestic aphasia was thought to be the least localizable. Conduction aphasics (n=11) : The lesions were relatively small in size. Many patients had posterior speech area lesions involving at least partially Wernicke's area. In particular, more than 80% of the conduction aphasics had lesions of the supramarginal gyrus and it's adjacent deep structures. Global aphasics (n=36) : In general, the size of the lesion was very large and 70% of the global aphasics had extensive lesions involving both Broca's and Wernicke's areas. However, there were observations showing that the lesions can be small and confined. (J.P.N.)

    One cause of recurrent spontaneous pneumothorax includes overlooking bullae during a previous surgery for pneumothorax; and the identification of the culprit lesions is necessary for prevention of recurrence. A 28-year-old man was referred to our hospital because of spontaneous right-sided pneumothorax. He underwent video-assisted thoracoscopic surgery, which did not reveal air leakage. The patient was subsequently seen at our hospital for 2 additional episodes of recurrent right-sided pneumothorax. At the third admission we observed intermittent air leakage while the patient was in the sitting position after chest drainage, and we performed surgery. An intraoperative submersion test showed air leakage dorsally from the pleural surface of S(6) and a minute culprit lesion, which were not seen at the first operation and confirmed the leakage site. The area was ligated and coated with regenerated oxidized cellulose mesh and autologous blood. In cases of pneumothorax with repeated recurrence, the best time to perform surgery on the patient with undetectable culprit lesion is the exact time that air leakage is observed.

    Full Text Available Despite recent advances in understanding the pathological pathways, clinical pattern and management opportunities for new-onset psoriasis as a paradoxical adverse event in patients receiving TNF inhibitors for their immune-mediated disorder, there is a subset of patients who are either partial responders or non-responders, whatever the therapeutic scenario. We present the case of new-onset psoriasis and severe alopecia development in a case study of long-standing rheumatoid arthritis (RA treated with adalimumab (ADA and leflunomide. Since skin lesions and alopecia are resistant to the classic protocol (topical treatment, ADA discontinuation and RA becomes highly active, rituximab (RTX was started. Dramatic improvement in joint disease, total remission of alopecia and partial remission of pustular psoriasis were described after the first RTX cycle. Although B-cell-depleting agents result in controversial effects on psoriatic skin lesions, this is the first case of ADA-induced psoriasis and alopecia that improved under RTX, suggesting a possible role in treating such a patient population.

    A 19-year-old women presented with a lytic lesion in the sacrum, associated with pain. Sinus histiocytosis (Rosai-Dorfman disease) was not diagnosed correctly until a biopsy specimen of an enlarged cervical lymph node showed the changes typical of sinus histiocytosis with massive lymphadenopathy. The disease was persistent in the patient and eventually involved the sternum. The patient improved with steroid therapy. The clinical, radiological and pathological aspects of this entity were discussed. It was stressed that radiologists, orthopedic surgeons and pathologists must be aware that sinus histiocytosis with massive lymphadenopathy may manifest initially as a bone 'tumor'.

    Full Text Available Spindle cell hemangioendothelioma (SCH was originally described by Weiss and Enzinger (1986 as a low-grade angiosarcoma resembling both cavernous hemangioma and Kaposi's sarcoma. Recent studies suggest that SCH is a benign neoplasm or reactive lesion accompanying a congenital or acquired vascular malformation. Most SCHs present as one or more nodules affecting the dermis or subcutis of the distal extremities. Few reports describe SCH of the head and neck region; even fewer note intramuscular SCH. Here, we describe a case of SCH involving the temporal muscle mimicking soft tissue sarcoma, who had a successful surgical treatment with a coronal approach and zygomatic osteotomy.

    2017-07-01

    Surgical treatment of lesions in the posterior thalamus, especially those extending laterally, is technically challenging because of a deep surgical field, narrow operative corridor, and the surrounding critical neurovascular structures. The authors describe an occipital transtentorial/falcine approach (OTFA) that was successfully used in the treatment of a cavernous malformation (CM) extending laterally from thalamus to midbrain. A 40-year-old man complained of progressive right hemiparesis and numbness. Radiological evaluation revealed a large CM in the left thalamus, surfacing on the pulvinar thalami, and extending 4 cm laterally from the midline. In addition to the usual procedures of a right-sided occipital transtentorial approach, the authors incised the falx cerebri to expand the operative corridor to the left thalamus. They achieved generous exposure of the left thalamus through a "cross-court" oblique trajectory while avoiding excessive retraction on the occipital lobe. The CM was completely removed, and no newly developed or worsening deficits were detected postoperatively. To better understand the OTFA and its application, the authors performed a cadaveric dissection. The OTFA provides increased exposure of the posterior thalamus without cortical incision and facilitates lateral access to this area through the "cross-court" operative corridor. This approach adds to the armamentarium for neurosurgeons treating thalamic lesions.

    Full Text Available Paracoccidioidomycosis (PCM is a deep mycosis with primary lung manifestations that may present cutaneous and oral lesions. Oral lesions mimic other infectious diseases or even squamous cell carcinoma, clinically and microscopically. Sometimes, the dentist is the first to detect the disease, because lung lesions are asymptomatic, or even misdiagnosed. An unusual case of PCM with 5 months of evolution presenting pulmonary, oral, and cutaneous lesions that was diagnosed by the dentist based on oral lesions is presented and discussed.

    Minimally invasive approaches to partial nephrectomy have been rapidly gaining popularity but require advanced laparoscopic surgical skills. Renal hilar tumors, due to their anatomic location, pose additional technical challenges to the operating surgeon. We compared the outcomes of robot-assisted partial nephrectomy (RPN) for hilar and nonhilar tumors in our large multicenter contemporary series of patients. We retrospectively reviewed prospectively collected data on 446 consecutive patients who underwent RPN by renal surgeons experienced in minimally invasive techniques at four academic institutions from June 2006 to March 2010. Patients were stratified into two groups: those with hilar lesions and those with nonhilar lesions. Patient demographics, operative outcomes, and postoperative outcomes, including oncologic outcomes, were recorded. Forty-one patients (9%) had hilar renal masses; 405 patients (91%) had nonhilar masses. There was no statistical differences in patient demographics except for larger median tumor size in the hilar cohort (3.2 cm vs 2.6 cm; p=0.001). The only significant difference in operative outcomes was an increase in warm ischemia times for the hilar group versus the nonhilar group (26.3±7.4 min vs 19.6±10.0 min; p=<0.0001). There were no differences in postoperative outcomes; however, there was a trend for increased risk of malignancy and higher stage tumors in the hilar lesion group. Final pathologic margin status was similar in both groups. Only one patient in the nonhilar group had evidence of recurrence at 21 mo. The study was limited by the lack of standard anatomic classification of renal tumors and the potential influence of the surgeons' prior robotic experience. The data represent the largest series of its kind and strongly suggest that RPN is a safe, effective, and feasible option for the minimally invasive approach to renal hilar tumors with no increased risk of adverse outcomes compared with nonhilar tumors in the hands of

    A 51-year-old man presented with elastofibroma (EF) of the gluteal region with a concomitant contralateral lesion. The patient presented with a slow growing mass of the proximal third of the right buttock and had swelling, discomfort in sitting, and right-hip pain during walking for 2 months. On MRI, a soft-tissue mass was noted between the gluteus maximus and the gluteus medius muscle. The mass showed similar signal intensity to the surrounding tissue on T1- and T2-weighted images and with linear hyperintense areas in its internal structure. At surgery, a soft, non-encapsulated, irregular, and rubber-like mass was found attached to the gluteus medius muscles. It was pathologically confirmed to be an EF. This unusual manifestation of an EF is discussed. (orig.)

    There is an increasing demand for a limited number of pigmented lesion clinic (PLC) visits at dermatology centers. To determine the proportion of visits to PLCs that are more frequent ("additional screening") than the recommended ("standard") follow-up schedule and to determine if certain patient characteristics correlate with the demand for these visits. A retrospective medical chart review of all PLC visits at an academic dermatology center from October 2010 to January 2012. A total of 609 patients associated with 1756 visits were identified. Of these, 25 patients associated with 26 visits were excluded owing to lack of melanoma diagnosis or risk factors, leaving 584 patients and 1730 visits. Diagnoses of these patients included in situ and invasive melanoma, dysplastic nevi, Spitz nevi, atypical nevus syndrome, family history of melanoma only, and other risk factors. The mean (SD) age was 48 (16) years, and 235 (40.2%) of the patients were male. The proportion of additional screening visits compared with standard visits. Standard visits were defined as occurring at the following frequencies: annually for mildly dysplastic nevi, Spitz nevi, or solely family history of melanoma; biannually for the first year, then annually thereafter for moderately dysplastic nevi or atypical nevus syndrome; biannually for up to 3 years, then annually thereafter for severely dysplastic nevi or melanomas in situ; every 3 months for 2 years, biannually for the following 2 years, then annually thereafter for invasive melanoma. A total of 1400 visits (80.9%) were standard, 257 (14.9%) were for additional screening, and 73 (4.2%) were "problem focused." Thirty percent of patients had at least 1 additional screening visit. The distribution of diagnoses among standard vs additional screening visits differed significantly, with "family history only" and "other risk factors" taking up a larger percentage of standard visits (15.1%) than the percentage of additional screening visits (8

    Morel-Lavallee lesions (MLLs) are rare internal degloving injuries typically caused by blunt traumatic injuries and most commonly occur around the hips and in association with pelvic or acetabular fractures. MLL is often overlooked in the setting of poly-trauma; therefore, clinicians must maintain a high degree of suspicion and be familiar with the management of such injuries, especially in obese poly-trauma patients. We present a 30-year-old female pedestrian struck by a motor vehicle who sustained multiple long bone fractures, a mesenteric hematoma, and full-thickness abdominal skin friction burn which masked a significant underlying abdominal MLL. The internal degloving caused significant devascularization of the overlying soft tissue and skin which required surgical drainage of hematoma, abdominal wall reconstruction with tangential excision, allografting, negative pressure wound therapy, and ultimately autografting. MLL is a rare, often overlooked, internal degloving injury. Surgeons must maintain a high index of suspicion when dealing with third degree friction burns as they may mask underlying injuries such as MLL, and a delay in diagnosis can lead to increased morbidity.

    Full Text Available The effects of a sudden addition of a large quantity of readily fermentable carbohydrate to the feed ration of pregnant heifers are described. Clinical and pathological changes caused by the resulting disease were confined to the digits and skin. The 4 acutely affected heifers were reluctant to get up or move (group II. They tended to lie down or stand with feet bunched together and the back arched, often shifting weight from limb to limb. They walked stiffly with great tenderness and pain in the digits. Extreme pain was noticed when the digits were examined. In 4 of 8 heifers, separation of the sole at the heel, with leakage of exudate, and under-running of the sole were observed. Necrotic dermatitis of the legs, alopecia and hyperkeratosis of the tail were noticed in all 8 heifers. Skin lesions appeared simultaneously. Four of the heifers (group I recovered, and the other 4 (group II were sent to slaughter. No post mortem examination was performed. The biochemical findings revealed a significantly higher concentration of total serum globulins and sodium, and increased activity, in CK, LDH and AST. A significantly decreasing pattern was noted in blood urea concentration, cholesterol, triglycerides, albumin and calcium. No significant differences among the various groups were found in the activities of amylase, GGT, and concentration of creatinine, total bilirubin, inorganic phosphorus, magnesium and potassium.

    Diabetic muscle infarction is a rare complication of diabetes. We describe 2 cases of diabetic muscle infarction, each one of them with a particular form of clinical presentation: recurrence, bilateral engagement, and unilateral compromise. Both cases had history of poorly controlled diabetes mellitus and diabetic nephropathy. The diagnosis was based on clinical, imaging, and anatomopathological features. The treatment was with a close control of diabetes mellitus, analgesics, short-term immobilization, and physical therapy.

    A Morel-Lavallée lesion is a post-traumatic closed degloving injury of soft tissue. The lesion is due to a shearing trauma with separation of subcutaneous tissue from underlying fascia. When conservative treatment fails, surgical treatment is imperative. Commonly, open drainage and debridement is performed. This case report describes a Morel-Lavallée lesion of the knee in a professional soccer player who was successfully treated with endoscopic debridement and fibrin glue injection after failure of conservative management. This method achieves the goal of an open surgical debridement without exposing patients to an increased morbidity. Copyright © 2016. Published by Elsevier B.V.

    Full Text Available Abstract Giant Osteosclerotic Lesions (GOLs are a group of rarely reported intraosseous lesions. Their precise diagnosis is important since they can be confused with malignant neoplasms. Objective This retrospective study aimed to record and analyze the clinical and radiographic Giant Osteosclerotic Lesions (GOLs detected in the maxillomandibular area of patients attending to our institution. Materials and Methods: Informed consent from the patients was obtained and those cases of 2.5 cm or larger lesions with radiopaque or mixed (radiolucid-radiopaque appearance located in the maxillofacial bones were selected. Assessed parameters were: age, gender, radiographic aspect, shape, borders, size, location and relations to roots. Lesions were classified as radicular, apical, interradicular, interradicular-apical, radicular-apical or located in a previous teeth extraction area. Additionally, several osseous and dental developmental alterations (DDAs were assessed. Results Seventeen radiopacities in 14 patients were found and were located almost exclusively in mandible and were two types: idiopathic osteosclerosis and condensing osteitis. GOLs were more frequent in females, and in the anterior and premolar zones. 94.2% of GOLs were qualified as idiopathic osteosclerosis and one case was condensing osteitis. All studied cases showed different osseous and dental developmental alterations (DDAs. The most common were: Microdontia, hypodontia, pulp stones, macrodontia and variations in the mental foramina. Conclusions GOLs must be differentiated from other radiopaque benign and malignant tumors. Condensing osteitis, was considered an anomalous osseous response induced by a chronic low-grade inflammatory stimulus. For development of idiopathic osteosclerosis, two possible mechanisms could be related. The first is modification of the normal turnover with excessive osseous deposition. The second mechanism will prevent the normal bone resorption, arresting the

    We report 3 year old male, referred for evaluation of developmental delays. Pregnancy was complicated by oligohydramnios, proteinuria and prematurity. Medical history revealed: bilateral inguinal hernia, small scrotal sac, undescended testes, developmental delays and behavioral problems. The child had: microcephaly, facial dysmorphic features, single palmar creases, hypopigmented skin lesions of variable size, intermittent exotropia and small retracted testes. Neurological examination was normal. Cognitive level was at the average range with mild delay in his adaptive behavior. Expressive language delays and severe articulation disorder were noted, as well as clumsiness, poor control and precision of gross and fine motor skills. Chromosomal analysis of peripheral leukocytes indicated that one of the number 11 chromosomes had undergone a pericentric inversion with breakpoints on the short (p) arm at band p14.3 and the long (q) arm at band q21. An MRI of the brain showed mild delay in myelinization pattern of white matter. Chromosome 11 inversion in other sites was associated with Beckwith-Wiedemann syndrome and several malignancies. To our knowledge this is the first description of inv(11)(p14.3q21) that is associated with microcephaly, dysmorphic features, hypopigmented skin lesions and speech delay. This inversion may disrupt the expression of the involved genes. However, additional cases with the same cytogenetic anomaly are needed to explore the phenotypic significance of this disorder.

    Full Text Available The loxoscelism is the most serious form of arachnidism in Brazil. The genus Loxosceles comprises more than 100 species of spiders in African and American continents. In Brazil, they are known as brown spiders. Nevertheless the great incidence of occurrence, few are the reports about repairing procedures, specially related to Physiotherapy after surgeries due to dermonecrosis. The aim of this case report was to register the Physiotherapeutic attendance of a female patient, 29 years old, victim of loxoscelism and who underwent debridement and skin transplantation for repairing right forearm lesions while she was interned at a hospital. Afterwards, data were confronted with the literature about loxoscelism, burns and Physiotherapy after skin transplantation. It is concluded that the patients with lesions caused by loxoscelism, who need repairing surgeries, may benefit a lot from Physiotherapeutic attendance while still at hospital. Although, factors such as: the lesion’s location, the cicatrization period, the number and complexity of surgeries, may be decisive for this indication.

    Free-living amoebas are exceedingly rare causes of cutaneous infections and present unique diagnostic and therapeutic challenges. We describe a case of disseminated acanthamoebiasis with cutaneous manifestations and summarize additional diagnostic, prognostic, and therapeutic highlights. A 58-year-old man with relapsed chronic lymphocytic leukemia had several weeks of progressive, painful ulcerations on the forehead, arms, abdomen, and thighs. A biopsy was performed for histopathologic evaluation. The biopsy specimen showed inflammatory infiltrate with abscess formation involving the epidermis, dermis, and subcutis. Scattered cells showed nuclei with a prominent central karyosome, dispersed chromatin, and either abundant foamy basophilic cytoplasm or two well-demarcated cytoplasmic walls. Acanthamoeba species was confirmed by polymerase chain reaction from the formalin-fixed, paraffin-embedded tissue. Cutaneous lesions from acanthamoebiasis are exceptionally rare but should be included in the differential diagnosis of necrotic cutaneous lesions in immunocompromised patients. Although infrequently encountered, pathologists need to be aware of the morphologic features of free-living amoebas. Immunohistochemical and molecular studies can confirm the diagnosis. Multiagent treatment regimens, when initiated empirically, have been more successful than single-agent regimens, but infections involving the central nervous system are almost universally fatal. © American Society for Clinical Pathology, 2016.

  13. High-grade squamous intraepithelial lesion (HSIL) of the cervix with bizarre cytological appearances ('pleomorphic HSIL'): a review of 19 cases.

    Stewart, Colin J R

    2017-08-01

    Cervical high-grade squamous intraepithelial lesions (HSILs) are typically characterised by a proliferation of immature basaloid cells with relatively uniform hyperchromatic nuclei. In this report we describe 19 cases of HSIL exhibiting focal but very marked nuclear atypia often associated with multinucleation ('pleomorphic HSIL'). The bizarre cytological changes mainly involved the basal epithelium particularly in endocervical crypts where the neoplastic cells undermined the native glandular epithelial cells. Superficially invasive squamous cell carcinoma (SISCCA) was present in three cases (16%) and while this was more common than in a comparative series of 40 'conventional' HSIL excision specimens (5%), the difference was not statistically significant. All three invasive cases demonstrated additional histological features that have been associated with increased risk of SISCAA (expansile crypt involvement by HSIL, luminal necrosis, and/or intraepithelial squamous maturation), and the invasive foci were associated microanatomically with conventional-type rather than pleomorphic HSIL. The bizarre cells expressed p16 and p63 proteins but usually lacked mitotic activity and showed less Ki-67 labelling than adjacent conventional HSIL. These findings suggest that pleomorphic epithelial changes in HSIL do not necessarily indicate more aggressive biological behaviour and may, in some cases, represent a degenerative phenomenon.

    2011-01-01

    Purpose: To evaluate the spectrum of MR cholangiography (MRCP) features of ischemic-type biliary lesions (ITBL) after orthotopic liver transplantation (OLT). Materials and Methods: 30 patients (16 m, 14 f) with an average age of 52 years (9 - 69 y) were examined in two 1.5 MR units using breath-hold 2D-SS-FSE-sequences and 3D-MRCP sequences. 20 of the 30 patients had an established ITBL, and the remaining 10 patients were post-OLT controls. MRCPs were evaluated independently by two experienced radiologists that were blinded to the clinical history as well as the results of other imaging modalities. All images were analyzed for the presence of 16 different pathological features. Differences between ITBL patients and controls were analyzed using the Mann-Whitney-U Test. Inter-rater variability was tested using the Cohen's Kappa test. Results: Abnormal findings of bile ducts were seen in all patients. The most common findings were (in percentage for reader 1/2) intrahepatic bile duct dilatation (95 %/95 %) and extrahepatic bile duct stenoses (95 %/85 %), followed by intrahepatic main duct stenoses (90 %/95 %) and segmental duct stenoses (85 %/85 %). Differences between ITBL patients and controls were significant for most of the analyzed features (Mann-Whitney-U test, p < 0.05). For 12 of 16 features, there was substantial or almost perfect agreement (K = 0.61 - 1.00), for 2 of 16 features moderate agreement (K = 0.41- 0.60) and for 2 of 16 features fair agreement (K < 0.40). Conclusion: In patients with ITBL, MR cholangiography reveals characteristic features that may allow differentiation from other biliary complications after liver transplantation. (orig.)

    A case of acute disseminated encephalomyelitis (ADEM) was presented. The patient was a 4-year-old boy with convulsion, ataxic gait, facial palsy. It was postulated that the influenza vaccine might induce the disease in this case. Cranial CT showed a low density arease in the right temporal lobe, which disappeared afterwards when other low density areas appeared in the right cerebellar hemisphere and in inner portion of the body of the left lateral ventricle. All symptoms disappeared without therapy and the CT findings improved within three months after onset. (author)

    A 40-year-old man complaining of progressive body weight loss was diagnosed to have acquired immunodeficiency syndrome. Within 2 weeks after the initiation of combination antiretroviral therapy, he developed fever, massive cervical lymphadenopathy and a protruding subcutaneous abscess. A lymph node biopsy and abscess drainage revealed non-caseous granuloma and mycobacterium. The mycobacterium belonged to Runyon II group, but it showed no matches to any previously reported species. According to sequence analyses, the strain was identified as Mycobacterium shigaense. After six months of antimycobacterial treatment, the lesions were all successfully cured. This is the third case report of the novel mycobacterium, M. shigaense, presenting in associatioin with immune reconstitution syndrome. PMID:27853087

    Full Text Available Introduction: Dose homogeneity within and dose conformity to the target volume can be a challenge to achieve when treating large area scalp lesions. Traditionally High Dose Rate (HDR brachytherapy (BT scalp moulds have been considered the ultimate conformal therapy. We have developed a new technique, Tangential Volumetric Modulated Arc Therapy (TVMAT that treats with the beam tangential to the surface of the scalp. In the TVMAT plan the collimating jaws protect dose-sensitive tissue in close proximity to the planning target volume (PTV. Not all the PTV is within the beam aperture as defined by the jaws during all the beam-on time. We report the successful treatment of one patient. Methods: A patient with biopsy proven extensive lentigo maligna on the scalp was simulated and three plans were created; one using a HDR brachytherapy surface mould, another using a conventional VMAT technique and a third using our new TVMAT technique. The patient was prescribed 55 Gy in 25 fractions. Plans were optimised so that PTV V100% = 100%. Plans were compared using Dose-Value Histogram (DVH analysis, and homogeneity and conformity indices. Results: BT, VMAT and TVMAT PTV median coverage was 105.51%, 103.46% and 103.62%, with homogeneity index of 0.33, 0.07 and 0.07 and the conformity index of 0.30, 0.69 and 0.83 respectively. The median dose to the left hippocampus was 11.8 Gy, 9.0 Gy and 0.6 Gy and the median dose to the right hippocampus was 12.6 Gy, 9.4 Gy and 0.7 Gy for the BT, VMAT and TVMAT respectively. Overall TVMAT delivered the least doses to the surrounding organs, BT delivered the highest. Conclusions: TVMAT was superior to VMAT which was in turn superior to BT in PTV coverage, conformity and homogeneity and delivery of dose to the surrounding organs at risk. The patient was successfully treated to full dose with TVMAT. TVMAT was verified as being the best amongst the three techniques in a second patient.

    2005-01-01

    Central pontine myelinolysis (CPM) is a demyelinating disease of the pons often associated with demyelination of other areas of the central nervous system (CNS). The etiology and pathogenesis of this disorder are still not fully understood. However, almost all cases of CPM are related to severe diseases or chronic alcoholism and occur in the setting of rapidly corrected serum hyponatremia and hypotonicity respectively. Depending on the involvement of other CNS structures, the clinical picture can vary considerably. Magnetic resonance imaging is the most sensitive investigation for the antemortem diagnosis of CPM, although the radiological findings lag behind and do not necessarily correlate with the clinical picture. Quite obviously diffusion-weighted imaging can be useful in the rapid diagnosis of CPM. This short review summarizes the current knowledge on the pathogenesis, clinical presentation, radiological findings, prognosis and therapeutic approaches of CPM. Characteristical clinical features and MR-findings including hyperintensity on diffusion-weighted images are illustrated by a typical case. (orig.)

    Primary extradural meningiomas of the skull comprise 1% of all meningiomas, and lytic skull meningiomas are still rarer and are said to be more aggressive. We present a case of 38-year-old male with an extradural tumor which on histopathological examination showed features of inflammatory atypical meningioma (WHO Grade II). The intense inflammatory nature of osteolytic primary intraosseous meningioma has not been reported before. This entity deserves special mention because of the need for adjuvant therapy and proper follow-up.

    Full Text Available Abstract Background Previous studies have provided some evidence of a possible association between cancer and metallothioneins. Whether this relates to an exposure to carcinogenic metals remains unclear. Methods In order to examine the association between the expression of metallothioneins and bladder tumors, and to compare the levels of arsenic, cadmium, chromium, lead and nickel in animals with bladder tumors and animals without bladder tumors, 37 cases of bovine bladder tumors and 17 controls were collected. The detection and quantification of metallothioneins in bladder tissue of both cases and controls was performed by immunohistochemistry. And the quantification of metals in tissue and hair was assessed by inductively coupled plasma – mass spectrometry. Results Increased expression of metallothioneins was associated with bladder tumors when compared with non-tumoral bladder tissue (OR = 9.3, 95% CI: 1.0 – 480. The concentrations of cadmium, chromium, lead and nickel in hair of cases were significantly higher than those of controls. However, as for the concentration of metals in bladder tissue, the differences were not significant. Conclusion Though the sample size was small, the present study shows an association between bladder tumors and metallothioneins. Moreover, it shows that concentrations of metals such as cadmium, chromium, lead and nickel in hair may be used as a biomarker of exposure.

    The purpose of this study was to determine inter- and intraobserver variability of MR arthrography of the shoulder in the detection and classification of superior labral anterior posterior (SLAP) lesions. MR arthrograms of 78 patients who underwent MR arthrography before arthroscopy were retrospectively analysed by three blinded readers for the presence and type of SLAP lesions. MR arthrograms were reviewed twice by each reader with a time interval of 4 months between the two readings. Inter- and intraobserver agreement for detection and classification of SLAP lesions were calculated using {kappa} coefficients. Arthroscopy confirmed 48 SLAP lesions: type I (n = 4), type II (n = 37), type III (n = 3), type IV (n = 4). Sensitivity and specificity for detecting SLAP lesions with MR arthrography for each reader were 88.6%/93.3%, 90.9%/80.0% and 86.4%/76.7%. MR arthrographic and arthroscopic grading were concurrent for 72.7%, 68.2% and 70.5% of SLAP lesions for readers 1-3, respectively. Interobserver agreement was excellent ({kappa} = 0.82) for detection and substantial ({kappa} = 0.63) for classification of SLAP lesions. For each reader intraobserver agreement was excellent for detection ({kappa} = 0.93, {kappa} = 0.97, {kappa} = 0.97) and classification ({kappa} = 0.94, {kappa} = 0.84, {kappa} = 0.93) of SLAP lesions. MR arthrography allows reliable and accurate detection of SLAP lesions. In addition, SLAP lesions can be diagnosed and classified with substantial to excellent inter- and intraobserver agreement.

    Full Text Available Introduction. This paper describes a case of bone augmentation with combination of Platelet-Rich Fibrin (PRF and β-TCP for treatment of chronic periapical cyst. The case was followed for 12 months. Methods. Patient presented with chronic periapical lesion in maxillary anterior teeth with history of trauma 8 years back. Radiographically, a periapical cyst was seen in relation to maxillary left central and lateral incisors. Conventional endodontic treatment was started. Since it was not successful, apical surgery was performed. Bone augmentation was done using PRF in combination with β-TCP bone graft to achieve faster healing of the periapical region. Regular followups at 3, 6, 9, and 12 months were done. Results. Healing was uneventful. Follow-up examinations revealed progressive, significant, and predictable clinical and radiographic bone regeneration/healing without any clinical symptoms. Conclusions. Combined use of PRF and β-TCP for bone augmentation in treatment of periapical defects is a potential treatment alternative for faster healing than using these biomaterials alone.

    Schistosomiasis mekongi was shown to be endemic, along the Mekong River, in northern Cambodia, affecting many patients with portal hypertension. Surgical procedures were proposed to some patients with digestive haemorrhage history to avoid fatal recurrence. The aim of our study was to evaluate the intensity of the liver fibrosis among these patients. During surgical treatment, liver biopsies were collected, fixed in Bouin or in formalin and processed at the Institut Pasteur of Cambodia. Sections were stained by H&E, Masson's trichrome, PAS, Ziehl-Neelsen's method and Congo Red. A total of six biopsies from patients aged 16-36 were analysed. There was complete disorganization of hepatic architecture with fibrous enlargement of portal tracts and some portal-portal bridging fibrosis, but there was no cirrhosis. In portal areas, there was blood vessel congestion and thrombosis with inflammation. Bile ducts were normal. In the parenchyma, congestion of sinusoidal capillaries was combined with focal mononuclear inflammatory infiltrate. There was no steatosis, no necrosis, no cholestasis, no iron accumulation and no amyloidosis. Numerous eggs of Schistosoma mekongi were observed in five cases, mostly in fibrous areas and more rarely in the parenchyma. Eggs were round or oval, measuring 60 x 40 microns with an acid-fast thin hyaline wall. Some eggs were surrounded by epithelioid and giant cell reaction. In conclusion, our findings illustrated a surprisingly high degree of fibrosis among young adults which contrasts with other schistosomiasis.

    This review provides updates on acute conditions affecting the periodontal tissues, including abscesses in the periodontium, necrotizing periodontal diseases and other acute conditions that cause gingival lesions with acute presentation, such as infectious processes not associated with oral bacterial biofilms, mucocutaneous disorders and traumatic and allergic lesions. A periodontal abscess is clinically important because it is a relatively frequent dental emergency, it can compromise the periodontal prognosis of the affected tooth and bacteria within the abscess can spread and cause infections in other body sites. Different types of abscesses have been identified, mainly classified by their etiology, and there are clear differences between those affecting a pre-existing periodontal pocket and those affecting healthy sites. Therapy for this acute condition consists of drainage and tissue debridement, while an evaluation of the need for systemic antimicrobial therapy will be made for each case, based on local and systemic factors. The definitive treatment of the pre-existing condition should be accomplished after the acute phase is controlled. Necrotizing periodontal diseases present three typical clinical features: papilla necrosis, gingival bleeding and pain. Although the prevalence of these diseases is not high, their importance is clear because they represent the most severe conditions associated with the dental biofilm, with very rapid tissue destruction. In addition to bacteria, the etiology of necrotizing periodontal disease includes numerous factors that alter the host response and predispose to these diseases, namely HIV infection, malnutrition, stress or tobacco smoking. The treatment consists of superficial debridement, careful mechanical oral hygiene, rinsing with chlorhexidine and daily re-evaluation. Systemic antimicrobials may be used adjunctively in severe cases or in nonresponding conditions, being the first option metronidazole. Once the acute

    Full Text Available Abstract Background No literature review exists on Mycoplasma pneumoniae-associated mild encephalitis/encepharopathy with a reversible splenial lesion (MERS. Methods M.pneumoniae-associated MERS cases were searched till August 2016 using PubMed/Google for English/other-language publications and Ichushi ( http://www.jamas.or.jp/ for Japanese-language publications. Inclusion criteria were children fulfilling definition for encephalitis, M.pneumoniae infection, and neuroimaging showing hyperintensity in the splenium of the corpus callosum (SCC alone (type I or SCC/other brain areas (type II. Results We described two children with type I and II M.pneumoniae-associated MERS. Thirteen cases found by the search and our 2 cases were reviewed. Mean age, male/female ratio, duration of prodromal illness was 8.3 years, 1.5 and 3.5 days. The most common neurological symptom was drowsiness, followed by abnormal speech/behavior, ataxia, seizure, delirium, confusion, tremor, hallucination, irritability, muscle weakness, and facial nerve paralysis. Fever was the most common non-neurological symptom, followed by cough, headache, gastrointestinal symptoms, headache, lethargy and dizziness. Seizure and respiratory symptoms were less common. All were diagnosed for M.pneumoniae by serology. Cerebrospinal fluid (CSF M.pneumoniae was undetectable by PCR in the 3 patients. Three patients were clarithromycin-resistant. Leukocytosis, positive C-reactive protein, hyponatremia, CSF pleocytosis and slow wave on electroencephalography frequently occurred. All except 2 were type I MERS. Neuroimaging abnormalities disappeared within 18 days in the majority of patients. All type I patients completely recovered within 19 days. Two type II patients developed neurological sequelae, which recovered 2 and 6 months after onset. Conclusions Prognosis of M.pneumoniae-associated MERS is excellent. Type II MERS may increase a risk of neurological sequelae.

    Myofibroma is a neoplasia of myofibroblasts that can be solitary or multiple and it is found most commonly in the head & neck region including scalp, forehead, parotid region and oral cavity. In the eyelid it is rarely reported. It has a benign course in the solitary form and fatal in its multiple form. A 4 month male infant referred to Farabi hospital -the referral center for eye diseases- with a 2 month history of a mass in his eyelid with gradual enlargement with no other complaints. The only abnormal physical finding was a 2.5 cm mass in the eyelid. This mass was excised and sent to the hospital pathology laboratory. When confronting a spindle cell lesion with a nodular or multinodular growth pattern which appears biphasic due to alteration of light and dark staining areas, the surgical pathologist should think to the possibility of myofibroma. Its pattern of growth and architecture rules out the other differential diagnoses like nodular fasciitis, fibrous histiocytoma, infantile fibromatosis, and peripheral primitive neuroectodermal tumor, mesenchymal chondrosarcoma, malignant hemangiopericytoma, juvenile fibrosarcoma and poorly differentiated synovial sarcoma. In difficult cases immunohistochemical staining is helpful that is Vimentin & Actin positivity & Desmin, CK, EMA & S100 negativity.

There were eight infectious conditions, 9 benign tumors, 11 malignant lesions and 3 miscellaneous cases. Diffuse chest wall thickening with heterogeneous echogenicity and obliteration of subcutaneous fat layer are findings of acute infection. In cases of tuberculous smpyema necessitates, pleural abnormality extended to the chest wall through intercostal space. Benign tumors were well demarcated, except in 4 cases of lipoma/lipomatosis. Malignant lesions showed irregular soft tissue masses, bone destruction, pleural effusion and subcutaneous invasion. Multiple enlarged lymph nodes were also shown. Ultrasound can demonstrate te internal structure, extent, depth and associated findings such as pleural effusion, bone destruction and peripheral lung involvement.

    We evaluated retrospectively the varying radiographic appearances of 15 solitary lucent epiphyseal lesions occurring in children. Imaging modalities used included plain films, conventional tomography, nuclear scintigraphy, and computed tomography. 40% of the lesions (6) were due to osteomyelitis. The remaining lesions included tuberculosis (1), foreign body granuloma (1), chondroblastoma (2), chondromyoxid fibroma (1), enchondroma (1), osteoid osteoma (2), and eosinophilic granuloma (1). Although the radiographic appearances of such lesions may be particularly characteristic, pathologic correlation is frequently necessary. The high incidence of osteomyelitis in our cases emphasizes its importance as a cause for a lucent epiphyseal lesion.

    As mammography has become more popular for the evaluation of breast symptoms and for the screening of asymptomatic women, the smaller lesions are being detected before they become palpable, therefore preoperative localization became necessary. This has led to the development of several methods for preoperative localization of nonpalpable lesions. Authors analyzed 50 cases with preoperative localization in 45 patients which had abnormal findings on film mammogram or ultrasonomammogram since October 1985 through March 1990 at Yongdong Severance Hospital, College of Medicine, Yonsei University. The results were as follows: 1. Techniques of localization were spot method in 8 cases, conventional needle localization method in 38 cases and Kopan's needle localization method in 4 cases. 2. The most common mammographic indication for localization was focal calcifications in 29 cases(58%), which was followed by a newly developed mass in 25 cases(50%). 3. Outcome of pathologically confirmed diagnosis put into benign lesions in 37 cases(74%) and malignant lesions in 13 cases(26%). 4. Among the cases with localization of lesions which has suggested as benign lesions in film and ultrasonomammogram,all cases(100%) were confirmed in benign lesions pathologically. Among the cases with localization of lesions which has suggested as malignant lesions in film and ultrasonomammogram, pathologic malignant has been proved of 44% and possible histopathologic precursor of malignant was resulted in 25% such as atypical hyperplasia and adenosis. Conclusively, authors consider that the abnormal areas should be removed in their entirety with the sacrifice of minimum volume of contiguous normal breast tissue through the preoperative localization, hence our preoperative localization has contributed favorable prognosis based on material lesions in early stage breast cancer.

    Heart structures have traditionally been considered radioresistant. In fact all tissues subjected to radiotherapy can develop lesions. Possible damage includes: - pericardiac fibrosis, the commonest and best individualized, associated with a constriction this leads to a stoppage pattern usually occurring late, around the 18th month. Its frequency depends directly on the total radiation dose; - fibrous myocarditis by direct damage to the heart muscle; - stenosis type lesions of the large coronary trunks; - in exceptional cases lesions of the aorta: hyperplastic degenerescence of the intima and adventitia or of the aortic sigmoid valvules and the mitral valves. Three observations are reported, concerning a coronary, a pericardiac and a coronary, myocardiac and pericardiac lesion. Following this account the irradiation techniques and main experimental data are reviewed and the prophylactic and therapeutic consequences to be derived from our observations and those of the literature are examined [fr

    Full Text Available BACKGROUND Macula is an important portion of retina that occupies the posterior pole of retina. Any disease that affects macula results in significant loss of central vision, form vision and colour vision to an extent. Macular lesions can be hereditary as well as acquired. Macular lesions occur in both younger and older individuals. Anatomically, a macular lesions can vary from a simple lesion like an RPF defect to a vision-threatening lesions like choroidal neovascular membrane. Many screening tests that are sensitive and specific are available to assess the functioning of macula called as ‘macular function test’. But, the greater understanding of the retinal vascular led to the usage of fluorescein angiogram in the detection and screening of macular, retinovascular and optic disc lesions. Through fundus fluorescein angiogram is a thirty-year-old procedure; it is still in vogue in almost all parts of the world. It has its own merits. The aim of the study is to study the role of fluorescein angiography in the evaluation of macular lesions. MATERIALS AND METHODS A hospital-based prospective randomised study was done, which included 50 patients. Detailed patient history was taken and thorough ocular and systemic examination was done. All patients were examined by ophthalmoscopy (direct and indirect and slit-lamp examination with 90D followed by fluorescein angiography. Ophthalmoscopic and fluorescein angiography findings were analysed and categorised. Patients were advised proper ocular and systemic treatment and follow up. RESULTS 50 cases with macular lesions were analysed and categorised into conditions like ARMD, CSR, macular oedema, CME, degenerations and dystrophies and miscellaneous conditions. FFA altered the diagnosis in 8% cases and categorised the cases in all cases. 16% patients developed adverse reactions like allergy, vomiting and nausea. On statistical analysis, FFA proved to be cheap and superior diagnostic tool in confirming

    The prognosis of patients with a subchondral insufficiency fracture remains unclear. The purpose of this study was to investigate the correlation between locations of bone marrow edema (BME) lesions and clinical outcome in patients with a subchondral insufficiency fracture of the hip. We retrospectively reviewed 15 consecutive hips in 14 patients who were diagnosed with subchondral insufficiency fracture of the hip at our institution between April 2013 and September 2014. This study included five males (six hips) and nine females (nine hips), ranging from 36 to 83 years of age (mean age: 66 years). The mean duration from the onset of hip pain to MRI examination was 1.8 months (range 0.5-5 months). Both clinical and imaging findings were investigated. Based on the findings of MR images, BME lesion in the femoral head alone was observed in six patients (six hips), BME lesion in the acetabulum alone was observed in one patient (two hips) and BME lesions in both the femoral head and acetabulum were observed in seven patients (seven hips). 3 of 15 hips resulted in rapidly destructive arthrosis and their BME lesions were observed in both the femoral head and acetabulum. 8 of 15 hips successfully healed by conservative treatment and BME lesions in 7 of these 8 hips were observed in only the femoral head or acetabulum. The results of this study indicate that the locations of BME lesions (femoral side alone, acetabular side alone or both) may be related to the clinical outcome in patients with a subchondral insufficiency fracture of the hip. Patients with subchondral insufficiency fracture of the hip in whom BME lesions were observed in both the femoral head and acetabulum may have a higher risk to need to undergo total hip arthroplasty.

    We report a case of thymic hyperplasia accompanied by pericardial lipomatosis and right facial hemihypertrophy in an 8-year-old boy. On imaging studies, the hyperplastic thymus had prominent curvilinear and nodular fatty areas simulating a fat-containing anterior mediastinal mass, which is an unusual finding in children. To our knowledge, this is the first report on a child with a combination of thymic hyperplasia, pericardial lipomatosis, and right facial hemihypertrophy. The radiologic findings are presented with a brief discussion.

    Awake craniotomy is a special method to prevent motor deficits during the resection of lesions that are located in, or close to, functional areas. Although it is more commonly performed in adult patients, reports of pediatric cases undergoing awake craniotomy are limited in the literature. In our clinic, where we frequently use awake craniotomy in adult patients, we performed this method in 2 selected pediatric cases for lesion surgery. At an early age, these 2 cases diagnosed with epilepsy presented cerebral lesions, but since the lesions enclosed functional areas, surgical resection was not regarded as a treatment option at this time. In these 2 pediatric cases, we successfully completed lesion surgery with awake craniotomy. The method and the techniques employed during surgery are presented concomitant with other reports in the literature. © 2016 S. Karger AG, Basel.

    Cancer of the breast is the second most common cause of cancer in women. Mass in the breast, whether benign or malignant is a cause of anxiety to the patients and the family members. All breast lumps are considered to be carcinomas until proved otherwise and are the causes of concern both for the patient and surgeon. This is a retrospective study conducted in Kathmandu Model Hospital for a total duration of three years from August 2007 to August 2010. 114 sample of breast tissue sent for histopathology were studied. Peak incidence of benign lesion was in between 21-30 years and malignant lesions in between 31-50 years. No breast lesions were seen in the first decade of life. Cancer of the breast was seen in 12.28% of cases. Fibroadenoma and fibrocystic disease were the commonest benign lesion and infiltrating ductal carcinoma was the commonest malignant lesion. Specimens from 10 male breasts were received. Gynaecomastia was the most common lesion encountered in males. Infiltrating ductal carcinoma was seen in a 70 year old male. Breast cancer is one of the commonest causes of breast lump particularly in women and is growing public health problem in Nepal.

    Background: The jaw (an unusual site of primary tumors in children and adolescents) has lesions often found incidentally by dentists on routine panoramic radiographs or during examination of a child who has swelling or tooth pain. Objective: This pictorial seeks to familiarize pediatric radiologists with the radiographic appearance of a variety of primary jaw lesions. Materials and methods: We retrospectively searched institutional records for cases of primary jaw lesions in children and adolescents. Jaw lesions were characterized as: I, well-circumscribed radiolucent lesions; II, lesions with mixed or variable appearance; III, poorly circumscribed radiolucent lesions; and IV, radiopaque lesions. Results: Although most oral and maxillofacial lesions in children are benign, a broad spectrum of tumors was identified; lesions may occur in patients with unrelated prior malignancy. Conclusion: Because radiologic studies may identify jaw lesions and direct further care, familiarity with the appearance of these entities is prudent. (orig.)

    Anti-N-methyl-D-aspartate receptor encephalitis is a severe autoimmune disorder characterized by severe psychiatric symptoms, seizures, decreased consciousness, autonomic dysregulation, and dyskinesias. Multifocal subcortical white matter lesions on fluid-attenuated inversion recovery and diffuse weighted images have rarely been reported in previous literature, and serial magnetic resonance imaging changes after plasma exchange have not been presented before. A previously healthy 24-year-old Chinese woman presented with acute psychiatric symptoms characterized by fear and agitation followed by decreased consciousness, dyskinesias, and seizures. Magnetic resonance imaging revealed hyperintense lesions on fluid-attenuated inversion recovery and diffuse weighted images in bilateral subcortical white matter. Cerebrospinal fluid analysis revealed a mild pleocytosis with lymphocytic predominance. Protein and glucose levels were normal. Aquaporin-4 antibodies in serum and cerebrospinal fluid were negative. Identification of anti-N-methyl-D-aspartate receptor antibodies in serum and cerebrospinal fluid confirmed the diagnosis of anti-N-methyl-D-aspartate receptor encephalitis. She was initially treated with combined intravenous immunoglobulin and methylprednisolone without improvement. Plasma exchange was then initiated with good response; the patient made a full recovery after several cycles of plasma exchange. Repeat magnetic resonance imaging performed 1 month after plasma exchange showed partial resolution of the hyperintense lesions in bilateral subcortical white matter, and follow-up magnetic resonance imaging 2 months after plasma exchange showed complete resolution. Anti-N-methyl-D-aspartate receptor encephalitis may be concomitant with multifocal subcortical white matter lesions. Such lesions may resolve after appropriate immunotherapy.

    We report 2 infantile cases of pulmonary tumor carrying a chimeric A2M-ALK gene. A2M-ALK is a newly identified anaplastic lymphoma kinase (ALK)-related chimeric gene from a tumor diagnosed as fetal lung interstitial tumor (FLIT). FLIT is a recently recognized infantile pulmonary lesion defined as a mass-like lesion that morphologically resembles the fetal lung. Grossly, FLIT characteristically appears as a well-circumscribed spongy mass, whereas the tumors in these patients were solid and firm. Histologically, the tumors showed intrapulmonary lesions composed of densely proliferating polygonal or spindle-shaped mesenchymal cells with diffuse and dense infiltrations of inflammatory cells forming microcystic or micropapillary structures lined by thyroid transcription factor 1-positive pneumocytes, favoring inflammatory myofibroblastic tumor rather than FLIT. The proliferating cells were immunoreactive for ALK, and A2M-ALK was identified in both tumors with reverse-transcription polymerase chain reaction. The dense infiltration of inflammatory cells, immunoreactivity for ALK, and identification of an ALK-related chimeric gene suggested a diagnosis of inflammatory myofibroblastic tumor. Histologically, most reported FLITs show sparse inflammatory infiltrates and a relatively low density of interstitial cells in the septa, although prominent infiltration of inflammatory cells and high cellularity of interstitial cells are seen in some FLITs. The present cases suggest that ALK rearrangements, including the chimeric A2M-ALK gene, may be present in these infantile pulmonary lesions, especially those with inflammatory cell infiltration. We propose that these infantile pulmonary lesions containing a chimeric A2M-ALK gene be categorized as a specific type of inflammatory myofibroblastic tumor that develops exclusively in neonates and infants.

    Intramammary ganglia are frequent mammographic findings of no pathological importance. We present two cases of malignant breast lesions whose mammographic appearance could resemble that of intramammary ganglia. Although the mammographic appearance of a lesion is similar to that of intramammary ganglia, it should be carefully studied, especially if it presents a poorly defined border or is palpable.

    Full Text Available Autoimmune pancreatitis (AIP can be chronic or recurrent, but frequently completely reversible after steroid treatment. A cystic lesion in AIP is a rare finding, and it can mimic a pancreatic cystic neoplasm. Difficulties in an exact diagnosis interfere with treatment, and surgery cannot be avoided in some cases. We report the history of a 63-year-old male presenting with jaundice and pruritus. AIP was confirmed by imaging and elevated IgG4 blood levels, and the patient completely recovered after corticosteroid therapy. One year later, he presented with a recurrent episode of AIP with elevated IgG4 levels, accompanied by the appearance of multiple intrapancreatic cystic lesions. All but 1 of these cysts disappeared after steroid treatment, but the remaining cyst in the pancreatic head was even somewhat larger 1 year later. Pancreatoduodenectomy was finally performed. Histology showed the wall of the cystic lesion to be fibrotic; the surrounding pancreatic tissue presented fibrosis, atrophy and lymphoplasmacytic infiltration by IgG4-positive cells, without malignant elements. Our case illustrates the rare possibility that cystic lesions can be part of AIP. These pseudocysts appear in the pancreatic segments involved in the autoimmune disease and can be a consequence of the local inflammation or related to ductal strictures. Steroid treatment should be initiated, after which these cysts can completely disappear with recovery from AIP. Surgical intervention may be necessary in some exceptional cases.

    2012-01-01

    Full Text Available A 72 year-old-male was referred to our institution with recalcitrant prepatellar bursitis. The injury was sustained after striking his right knee against a post whilst horse riding 9 months ago. Previous treatments included repeated aspiration and excision of the bursa with elastic compression bandaging. A diagnosis of a Morel-Lavallée internal degloving injury was made, and the lesion was satisfactorily managed by an internal quilting procedure to eliminate the potential dead space. A review of the literature reveals 29 published reports of Morel-Lavallée lesions with sufficient information for inclusion. These came from 14 separate countries with a total of 204 lesions in 195 patients. The most common anatomical location was the greater trochanter/hip (36%, followed by the thigh (24% and the pelvis (19%. Most were managed surgically with evacuation of the haematoma and necrotic tissue followed by debridement, which was often repeated (36%. Conservative treatment with percutaneous aspiration and compression bandaging was the next most common treatment (23%. The knee was the fourth most common region affected (16%, and only 3 other lesions in the literature have been managed with a quilting procedure.

    The positron scanning method with Cu{sup 64} and As{sup 74} for the diagnosis of brain tumours has the advantage over {gamma}-scanning methods that it needs a shorter test time and moreover involves less irradiation hazards. This is especially true with Cu{sup 64} (half-life 12.8 h), which may be used in studies on out-patients. From the degree of concentration of the radioactive substance in the tumour, its type may be determined. In combination with cerebral angiography, the diagnosis of the type of tumour is still better established, a fact which is very important in determining the indication for operation. In the present, study, the exactness of the diagnosis amounted to 75- 80% of all cases of brain tumours. The most easily recognized lesions, through their high ability to concentrate the isotopes, were the meningiomas, abscesses and glioblastomas, while the oligodendrorogliomas and astrocytomas showed less ability to concentrate the radioactive substance and hence were less easily recognizable. A group of astrocytomas and almost all epidermoid tumours did not show any ability to concentrate the radioactive substance and in this group the combination with cerebral angiography is important for determining the diagnosis. The method of positron-scanning has proved of great value in excluding tumours in cases of suspected symptomatic epilepsy; the exactness of diagnosis here amounted to 90%. The combination of electro-encephalography with scanning showed similar accuracy in tumour diagnosis as well as tumour exclusion, so that arteriography and/or hospital admission could be dispensed with whenever combined negative findings and lack of clinical symptoms were found. The value of this method in examination, of out-patients is thus clearly demonstrated.

    Purpose: To evaluate the spectrum of MR cholangiography (MRCP) features of ischemic-type biliary lesions (ITBL) after orthotopic liver transplantation (OLT). Materials and Methods: 30 patients (16 m, 14 f) with an average age of 52 years (9 - 69 y) were examined in two 1.5 MR units using breath-hold 2D-SS-FSE-sequences and 3D-MRCP sequences. 20 of the 30 patients had an established ITBL, and the remaining 10 patients were post-OLT controls. MRCPs were evaluated independently by two experienced radiologists that were blinded to the clinical history as well as the results of other imaging modalities. All images were analyzed for the presence of 16 different pathological features. Differences between ITBL patients and controls were analyzed using the Mann-Whitney-U Test. Inter-rater variability was tested using the Cohen's Kappa test. Results: Abnormal findings of bile ducts were seen in all patients. The most common findings were (in percentage for reader 1/2) intrahepatic bile duct dilatation (95 %/95 %) and extrahepatic bile duct stenoses (95 %/85 %), followed by intrahepatic main duct stenoses (90 %/95 %) and segmental duct stenoses (85 %/85 %). Differences between ITBL patients and controls were significant for most of the analyzed features (Mann-Whitney-U test, p < 0.05). For 12 of 16 features, there was substantial or almost perfect agreement (K = 0.61 - 1.00), for 2 of 16 features moderate agreement (K = 0.41- 0.60) and for 2 of 16 features fair agreement (K < 0.40). Conclusion: In patients with ITBL, MR cholangiography reveals characteristic features that may allow differentiation from other biliary complications after liver transplantation. (orig.)

    We evaluated the MR and CT findings of the masticator space lesions in order to identify the differences among the malignant and benign tumors and infectious conditions. MR and CT findings in 46 cases with proven masticator space lesions were reviewed retrospectively. We analysed the involvement of masticator muscles, adjacent spaces, orbit and intracranium, homogeneity, necrosis, cystic changes, growth patterns, calcifications, enhancement patterns, MR signal intensity, and CT attenuation. Among the 29 cases of malignant tumors, seven cases were mandibular tumors including four chondrosarcomas, and 22 cases were extramandibular tumors. Malignant tumors of mandibular origin showed large masses with severe bone destruction and epicenter of mandible. Extramandibular malignant tumors showed the epicenter out of the mandible and less severe bone destruction than mandibular tumors. Among the nine benign tumors, four cases were ameloblastomas which showed the well-defined masses and the expansion of the mandible, and four cases were extramandibular tumors which showed well-marginated extramandibular masses with no bone destruction. Among the eight infectious conditions, five cases were mandibular osteomyelitis with or without abscess formations, and the other three cases were infections from adjacent soft tissue or limited to the soft tissue. By careful observations of growth patterns, involvement of the masticator and adjacent spaces, bone changes, and epicenter of the lesions, one can discriminate a mandibular lesion from an extramandibular lesion. With this approach, it is thought to be easier to suggest a diagnosis among a wide spectrum of masticator lesions

    Full Text Available The aim of the research was to present the clinical observations of neoplastic lesions of the appendix (one carcinoid and two mucous cysts and to discuss various manners of treatment and prognosis. Material and methods: The authors of the following paper present a description of three cases of appendix tumours, two patients with a mucous cyst and a patient with carcinoid, against the background of all the appendectomies performed at the Clinical Department of General, Endocrine and Oncological Surgery of the Provincial Polyclinical Hospital in Kielce in the years 2005–2011. Results : Within the 7-year period, a total of 11 719 surgical operations have been performed, where 834 (7.1% were that of appendectomy. Among all of the removed vermiform appendixes, neoplastic lesions occurred in three cases constituting a mere 0.3% of all of the appendectomies performed within that period. In two of the cases there was a suspicion of mucous cysts before the surgical operation. In none of the above-mentioned cases was is possible to ultimately establish the diagnosis before the operation. The patients were subjected to a simple appendectomy. The patients are in good clinical health, with no signs of relapse. Conclusions : The presented cases of patients with appendix tumours illustrate the difficulty of preoperative detection of a neoplastic lesion. This is mainly due to a scantily symptomatic course or symptoms typical of appendicitis. In light of this, histopathological examination of each appendix should be treated as obligatory.

    Full Text Available BACKGROUND A multitude of lesions occur in the neck and patients come to hospital on account of morbidity associated with these lesions. Therefore a histopathological study of the spectrum of neck lesions was undertaken. MATERIALS AND METHODS All histologically diagnosed lesions of the neck from January 2014 to December 2015 were noted. Details of gender, age, location and diagnosis were recorded. The lesions were classified based on anatomic location, gross and histological features and clinically. Clinically, lesions were classified as congenital, inflammatory/infective and neoplastic. Incidence of age, gender and location of different lesions was calculated using percentage, and median. The findings were compared with other studies. RESULTS A total of 140 neck lesions were included in the current study. Neck lesions were predominant in females with 94 cases. The median age group involved was the 21-30 group. Anterior neck lesions were more common. Anterior midline lesions were 74 and mostly thyroid and thyroglossal duct origin. Lesions of the lymph node were greater in the posterior triangle. 122 lesions were solid and 18 were cystic. Histologically, there were 64 thyroid gland lesions, 40 lymph node lesions, 13 soft tissue tumours, 8 salivary lesions, 10 thyroglossal cysts and 5 skin/adnexal lesions. Clinically, congenital/developmental lesions were 11, inflammatory/infective lesions were 68 and neoplastic lesions were 61. Of the neoplastic lesions, 17 were malignant. CONCLUSION Non-neoplastic lesions of the neck were common in our study in accordance with findings in other studies. The most common malignancy was Papillary carcinoma of thyroid.

    1985-01-01

    In the course of life the periodontum is subject to changes which may be physiological or pathological. Intraoral radiographs give insight into the hard structures of the dentomaxillar region and provides information on lesions in the bone of the periodontum in that they show radiopacities and radiolucencies caused by such lesions. In this thesis the relation is investigated between the true shape and dimensions of periodontal bone lesions and their radiographic images. A method is developed and tested of making standardized and reproducible radiographs suitable for longitudinal studies of periodontal lesions. Also the possibility is demonstrated of an objective and reproducible interpretation of radiographic characteristics of periodontal bone lesions. (Auth.)

    Background: The hypervascular liver lesions represent a diagnostic challenge. Aim: To identify risk factors for cancer in patients with non-hemangiomatous hypervascular hepatic lesions in radiologically normal liver. Method: This prospective study included patients with hypervascular liver lesions in radiologically normal liver. The diagnosis was made by biopsy or was presumed on the basis of radiologic stability in follow-up period of one year. Cirrhosis or patients with typical imaging characteristics of haemangioma were excluded. Results: Eighty eight patients were included. The average age was 42.4. The lesions were unique and were between 2-5 cm in size in most cases. Liver biopsy was performed in approximately 1/3 of cases. The lesions were benign or most likely benign in 81.8%, while cancer was diagnosed in 12.5% of cases. Univariate analysis showed that age >45 years (p< 0.001), personal history of cancer (p=0.020), presence of >3 nodules (p=0.003) and elevated alkaline phosphatase (p=0.013) were significant risk factors for cancer. Conclusion: It is safe to observe hypervascular liver lesions in normal liver in patients up to 45 years, normal alanine amino transaminase, up to three nodules and no personal history of cancer. Lesion biopsies are safe in patients with atypical lesions and define the treatment to be established for most of these patients. (author)

    The authors report stereotactically created lesioning by radiofrequency or Cyberknife radiosurgery for patients with mental illness. Since 1993, thirty-eight patients have undergone stereotactic psychosurgery for medically intractable mental illnesses. Two patients had aggressive behavior. Twenty-five patients suffered from Obsessive-Compulsive Disorder (OCD) and ten patients had depression. Another patient suffered from atypical psychosis. Bilateral amygdalotomy and subcaudate tractotomy were done for aggressive behavior. Limbic leucotomy or anterior cingulotomy was done for CCD and subcaudate tractotomy with or without cingulotomy was done for depression. In twenty-three patients, the lesions were made by a radiofrequency (RF) lesion generator. In fifteen cases, the lesions were made with Cyberknife Radiosurgery (CKRS). The Overt Aggression Scale (OAS) declined from 8 to 2 with clinical improvement during follow up period. With long-term follow up (meaning 57 months) in 25 OCDs, the mean Yale Brown Obsessive Compulsive Score (YBOCS) declined from 34 to 13 (n = 25). The Hamilton Depression scale (HAMD) for ten patients with depression declined from 38.5 to 10.5 (n = 10). There was no operative mortality and no significant morbidity except one case with transient urinary incontinence. Authors suggest that stereotactic psychosurgery by RF and CKRS could be a safe and effective means of treating some medically intractable mental illnesses. (author)

    A 49-year-old man presented with a 30-year history of oral and genital aphthous ulcers and joint pain. One day before his admission he developed double vision and weakness in the right extremities. Neurological examination revealed right 5th nerve palsy, left 6th to 18th nerve palsy, left Horner's sign, and motor and sensory impairment in the right upper and lower extremities. X-ray CT showed diffuse, weak, low-density areas in the brainstem. T1 weighted images showed low signals in the left side of the mid-pons, the left tegmentum and the right basis of the upper pons, and the left tegmentum of the midbrain. T2 weighted images showed high signals in the whole pons and the left side of the midbrain. MRI allowed the differentiation of reversible lesions, such as brain edema, and irreversible lesions, such as necrosis and demyelination of the tissue. (Namekawa, K.).

    As compared to other organs and tissues liable to sustain delayed injury from radiotherapy, the musculature seems to be a hard-wearing, radiation-resistant organ. Apart from the possibility of inducing Myodegeneratio cordis, muscles are merely threatened, as far as is known today, by possible fibrosis in the surrounding area. Certainly, extremely high doses of more than 100 Gy occasionally may trigger necrosis and atrophies in tissues. The article reports on a patient suffering from carcinoma of the bladder who developed muscle and tendon degeneration following telecobalt irradiation after a latency period of eight years, forcing him ultimately to quit work.

    Introduction . The triangular fibrocartilage complex (TFCC) provides both mobility and stability of the radiocarpal joint. TFCC lesions are difficult to diagnose due to the complex anatomy. The standard treatment for TFCC lesions is arthroscopy, posing surgery-related risks onto the patients. This feasibility study aimed at developing a workup for soft-tissue reconstruction using clinical imaging, to verify these results in retrospective patient data. Methods . Microcomputed tomography ( μ -CT), 3 T magnetic resonance imaging (MRI), and plastination were used to visualize the TFCC in cadaveric specimens applying segmentation-based 3D reconstruction. This approach further trialed the MRI dataset of a patient with minor radiological TFCC alterations but persistent pain. Results . TFCC reconstruction was impossible using μ -CT only but feasible using MRI, resulting in an appreciation of its substructures, as seen in the plastinates. Applying this approach allowed for visualizing a Palmer 2C lesion in a patient, confirming ex postum the arthroscopy findings, being markedly different from MRI (Palmer 1B). Discussion . This preliminary study showed that image-based TFCC reconstruction may help to identify pathologies invisible in standard MRI.

    Full Text Available Introduction. The triangular fibrocartilage complex (TFCC provides both mobility and stability of the radiocarpal joint. TFCC lesions are difficult to diagnose due to the complex anatomy. The standard treatment for TFCC lesions is arthroscopy, posing surgery-related risks onto the patients. This feasibility study aimed at developing a workup for soft-tissue reconstruction using clinical imaging, to verify these results in retrospective patient data. Methods. Microcomputed tomography (μ-CT, 3 T magnetic resonance imaging (MRI, and plastination were used to visualize the TFCC in cadaveric specimens applying segmentation-based 3D reconstruction. This approach further trialed the MRI dataset of a patient with minor radiological TFCC alterations but persistent pain. Results. TFCC reconstruction was impossible using μ-CT only but feasible using MRI, resulting in an appreciation of its substructures, as seen in the plastinates. Applying this approach allowed for visualizing a Palmer 2C lesion in a patient, confirming ex postum the arthroscopy findings, being markedly different from MRI (Palmer 1B. Discussion. This preliminary study showed that image-based TFCC reconstruction may help to identify pathologies invisible in standard MRI. The combined approach of μ-CT, MRI, and plastination allowed for a three-dimensional appreciation of the TFCC. Image quality and time expenditure limit the approach’s usefulness as a diagnostic tool.

    The distribution of the lesions responsible for aphasia unassociated with right-sided hemiparesis was evaluated by cranial computed tomography (CT) among stroke patients. In the Broca aphasia group were observed atypical aphasic symptoms, and the lesions were far more localized than in ordinary Broca one. In the Wernicke aphasia group showed relatively large lesions in the left superior temporal gyrus, sometimes extending to supramarginal and angular gyri, which caused such additional symptoms as apraxia without motor paresis in some cases. In the Transcortical motor aphasia group showed the occlusion of the left internal carotid artery, though without obvious abnormality at CT. In another patient a circumscribed low density lesion was disclosed in the area anterior and superior to so-called Broca's area. In the Transcortical sensory aphasia group, the lesion involved the borderzone supplied by the left middle and posterior cerebral arteries. In the Amnestic aphasia group showed a lesion in the left parietal lobe, while in another no remarkable change was demonstrated. In the Global aphasia group, one had multiple isolated lesions in both anterior and posterior speech areas. Another showed a large lesion involving the whole territory of the left middle cerebral artery. In the remaining one a high density area was observed in the left superior temporal, supramarginal and angular gyri, not extending to the frontal lobe beyond with sylvian fissure. Therefore, in interpreting CTs of such aphasic patients we must take account of not only the extent of the lesion but also the severity of destruction. (J.P.N.)

  15. Visible and occult microscopic lesions of endometriosis

    Full Text Available Endometriosis is a multifactorial disease mostly affecting women of reproductive age and is associated with chronic pelvic pain and infertility. Even after 300 years, most of the literature claims that pathogenesis and/or pathophysiology of endometriosis is still elusive. Recurrence of pain and lesion continues to occur after effective medical or surgical therapies. Once generated within the pelvis due to retrograde entry of menstrual debris, peritoneal endometriotic lesions time-dependently change their color appearance resulting from certain biochemical change within lesions. A variable pattern of endometriotic lesions within the pelvis can be detected by laparoscopy as visible peritoneal endometriosis. It is generally believed that besides ovarian steroid hormones, the growth of endometriosis can be regulated by the innate immune system in the pelvic microenvironment by their interaction with endometrial cells and immune cells. Even with the careful eyes of an expert surgeon, we may sometimes miss detecting peritoneal lesion within the peritoneal cavity or deep into the peritoneum. In such a case, random collection of normal peritoneum may carry the possibility to identify some hidden endometriotic lesions by microscopy and these lesions can be named as occult (invisible microscopic endometriosis (OME. Here, we discuss the color appearance of peritoneal lesions and activity of these lesions by analysis of a panel of activity markers. Finally we discuss our recent findings on OME, their biological and clinical significance, and try to make a possible link in the origin between visible endometriosis and OME.

    A large variety of tumor and tumor-like conditions have been shown to originate from the surface of bone. Most surface lesions are associated with periosteal reaction. The periosteum is a multipotential membrane. Its cellular composition may give rise to a variety of both neoplasms and tumor-like conditions. To avoid misinterpretation, the orthopedist, radiologist, and pathologist should be familiar with the entire spectrum of surface lesions. A better understanding of the natural history and biological behavior at different lesional maturity stages and correlation of the history with the radiographic and pathological findings is essential to establish the correct diagnosis. A history of injury of blunt trauma is very important. A stress fracture may produce a periosteal reaction acd callus that can be difficult to distinguish from osteosarcoma. In this review article, the authors wish to describe and define each term by its anatomy and radiographic features while discussing the entire spectrum of surface lesions. All the illustrative cases in this review article have been proven histologically. (orig.)

    Full Text Available Ghost cells have been a controversy for a long time. Ghost cell is a swollen/enlarged epithelial cell with eosnophilic cytoplasm, but without a nucleus. In routine H and E staining these cells give a shadowy appearance. Hence these cells are also called as shadow cells or translucent cells. The appearance of these cells varies from lesion to lesion involving odontogenic and nonodontogenic lesions. This article review about the origin, nature and significance of ghost cells in different neoplasms.

    Full Text Available The cyclops lesion is a localized anterior arthrofibrosis most commonly seen following anterior cruciate ligament reconstruction. The lesion forms at the anterior cruciate ligament insertion creating a painful extension block between femoral intercondylar notch and tibial plateau. We present 2 cases (3 knees in which cyclops lesions appeared atypically following bicruciate-retaining total knee replacement. Two lesions occurred in a single patient following bilateral knee replacement. One lesion occurred in an active sportswoman. All 3 resolved following arthroscopic debridement. We describe the presentation of this unusual complication and suggest keys to its diagnosis, treatment, and prevention.

We present our initial experiences with the latest technical advance in this technique, the automated breast volume scanner (ABVS ACUSON S2000TM. Volume data sets were collected from 50 patients and a database containing 23 women with no detectable lesions in conventional ultrasound (BI-RADS®-US 1, 13 women with clearly benign lesions (BI-RADS®-US 2, and 14 women with known breast cancer (BI-RADS®-US 5 was created. An independent examiner evaluated the ABVS data on a separate workstation without any prior knowledge of the patients’ histories. The diagnostic accuracy for the experimental ABVS was 66.0% (95% confidence interval [CI]: 52.9–79.1. The independent examiner detected all breast cancers in the volume data resulting in a calculated sensitivity of 100% in the described setting (95% CI: 73.2%–100%. After the ABVS examination, there were a high number of requests for second-look ultrasounds in 47% (95% CI: 30.9–63.5 of the healthy women (with either a clearly benign lesion or no breast lesions at all in conventional handheld ultrasound. Therefore, the specificity remained at 52.8% (95% CI: 35.7–69.2. When comparing the concordance of the ABVS with the gold standard (conventional handheld ultrasound, Cohen’s Kappa value as an estimation of the inter-rater reliability was κ = 0.37, indicating fair agreement. In conclusion, the ABVS must still be regarded as an experimental technique for breast ultrasound, which

    Intraosseous vascular lesions of the maxillofacial region are rare, and the differential diagnosis of intraosseous vascular malformations from other jaw lesions can be challenging. In the present case, magnetic resonance imaging and three-dimensional computed tomographic angiography (CTA) was used for diagnosis, and the lesion was treated with surgical excision. Diverse characteristics such as the 'honeycomb' and 'sunburst' radiographic appearances and the absence of major peripheral feeder vessels in the CTA were noted. Intraosseous vascular malformations have a varied radiographic appearance, and the nomenclature of these lesions is equally diverse, with several overlapping terms. Pathologists do not generally differentiate among intraosseous vascular lesions on the basis of histopathology, although these lesions may present with contrasting immunohistochemical and clinical behaviors requiring varied treatment strategies. This case report highlights the need for multiple imaging modalities to differentiate among vascular lesions, as well as to better understand the behaviors of these unique lesions.

    Without peritreatment antibiotics, infectious flare-ups (about 15% incidence) and serious sequelae follow endodontic treatment of asymptomatic teeth with necrotic pulps and associated periapical lesions. Antibiotics administered after endodontic treatment (4-day regimen) reduce the flare-up incidence to about 2%, but hypersensitivity responses, sensitization, resistant microbes, and drug-taking compliance are potential problems. To ascertain whether a specific prophylactic antibiotic (high-dose, 1-day regimen) would preferentially maintain this low flare-up incidence while overcoming antibiotic-related problems, 315 patients with quiescent pulpal necrosis and an associated periapical lesion were randomly given either penicillin V or erythromycin (base or stearate). Evaluations of flare-up after endodontic treatment were done at 1 day, 1 week, and 2 months. A 2.2% flare-up incidence was found, with no statistically significant differences for penicillin (0.0%), base (2.9%), and stearate (3.8%). No hypersensitivity responses occurred. Gastrointestinal side effects were found primarily with the erythromycins (12.4%). A comparative analysis of the data from our first study (no peritreatment antibiotics) and the pooled data from our last two investigations (including the current trial) showed that peritreatment antibiotic coverage significantly reduced flare-ups and serious sequelae after endodontic treatment (p less than 0.001).

    1. Retrospectively evaluate the accuracy of tentative diagnosis or impression from the clinico-radiographic materials of jaw lesions which showed mixed lesions associated with teeth. 2. To observe the diagnostic importance of the calcified part of the lesions which appear as radiopaque areas. 14 cases of jaw lesions which showed mixed lesions associated with teeth were reviewed. These lesions were mostly diagnosed as adenomatoid odontogenic tumors (6 cases) or calcifying odontogenic cysts with (4 cases) or without odontomas (4 cases). The calcified elements of the lesions which demonstrated various sizes and patterns of radiopaque shadows resembled odontoid tissues in some cases but could not be defined in some other cases radiographically. The final histopathologic diagnosis confirmed adenomatoid odontogenic tumors in 4 of the 6 cases. The remaining 2 cases turned out to be odontoma and ameloblastic fibroodontoma. The 4 cases of calcifying odontogenic cysts with odontomas were correct in 3 cases but remaining 1 case was just odontoma. The 4 cases of calcifying odontogenic cysts were proved to be odontogenic keratocyst, calcified peripheral fibroma, unicystic ameloblastoma and squamous cell carcinoma. The diagnostic accuracy of the adenomatoid odontogenic tumors and calcifying odontogenic cysts were high when the lesions show typical appearance. The calcifications which show radiopaque areas could be odontomas or dystrophic calficifations or remnants of bone fragments from resorption.

    Evolution of the early bone lesions in two children with mucolipidosis 2 was followed from birth. The progression of the bone changes did not differ from healing of rickets. Low levels of 1,25-OH{sub 2}-D3 were found in one child and he was treated with vitamin D; resolution of the rachitic changes was more rapid than in the untreated child. It is suggested that in mucolipidosis 2 bone reacts to two independent factors, one controlling calcium metabolism, the other depending on the primary lysosomal enzyme defect. Since ricket-like features are not present in the other mucolipidoses or mucopolysaccharidoses, the defect of calcium metabolism seems to be related to the specific enzyme defect of mucolipidosis 2.

Four experienced musculoskeletal radiologists studied plain radiographs and other imaging documents of histologically-proven Nora's lesions, looking for soft-tissue changes, periosteal reaction/calcification and calcified/ossified pseudotumours, and compared those findings with findings on pathology reviewed by a peer group of pathologists. Twenty-four Nora's lesions originating from a series of 200 consecutive, histologically-verified bone (pseudo)tumours of the hand, seen by the ''Netherlands Committee on Bone Tumours'' for review and second opinion. Nora's lesions have a recognised presentation on radiographs without specific MR characteristics. Natural evolution could be assessed retrospectively in four cases. Recurrent lesions were seen in seven cases and are difficult to differentiate from primary Lesions. (orig.)

    The purpose of this study was to establish volumetric exchangeability between real and computational lung lesions in CT. We compared the overall relative volume estimation performance of segmentation tools when used to measure real lesions in actual patient CT images and computational lesions virtually inserted into the same patient images (i.e., hybrid datasets). Pathologically confirmed malignancies from 30 thoracic patient cases from Reference Image Database to Evaluate Therapy Response (RIDER) were modeled and used as the basis for the comparison. Lesions included isolated nodules as well as those attached to the pleura or other lung structures. Patient images were acquired using a 16 detector row or 64 detector row CT scanner (Lightspeed 16 or VCT; GE Healthcare). Scans were acquired using standard chest protocols during a single breath-hold. Virtual 3D lesion models based on real lesions were developed in Duke Lesion Tool (Duke University), and inserted using a validated image-domain insertion program. Nodule volumes were estimated using multiple commercial segmentation tools (iNtuition, TeraRecon, Inc., Syngo.via, Siemens Healthcare, and IntelliSpace, Philips Healthcare). Consensus based volume comparison showed consistent trends in volume measurement between real and virtual lesions across all software. The average percent bias (+/- standard error) shows -9.2+/-3.2% for real lesions versus -6.7+/-1.2% for virtual lesions with tool A, 3.9+/-2.5% and 5.0+/-0.9% for tool B, and 5.3+/-2.3% and 1.8+/-0.8% for tool C, respectively. Virtual lesion volumes were statistically similar to those of real lesions (.05 in most cases. Results suggest that hybrid datasets had similar inter-algorithm variability compared to real datasets.

    Degenerative lesions of the peripheral retina are present from teenage years onwards and increase with age. These abnormabilities are frequent, some of them being benign while others predispose to retinal tears and detachment. In the latter case, the lesions are rhegmatogenous and may justify prophylactic treatment by laser photocoagulation. We distinguish congenital lesions of the peripheral retina and intraretinal, chorioretinal and vitreoretinal degenerations. The holes and tears observed in 2% of the population consist of round atrophic holes, "horseshoe" tears, oral dialyses and giant tears. Copyright © 2013 Elsevier Masson SAS. All rights reserved.

    The pattern of the focal bone lesion which consists partly or wholly of rounded holes with comparatively smooth edges is discussed. Twenty-two bone lesions were studied by angiography. The 'hypervascular pattern' occurred in five cases of widely different histology, all with strong intraosseous hypervascularity. Different pathogenic mechanisms in the creation of this pattern are discussed. It is probably the result of both destructive and reparative processes in the bone. (orig.)

    Purpose of this work is to assess MR potentials in the evaluation of superior glenoid labrum disease and possible associated conditions of the rotator cuff and of the anterior mechanism of the shoulder. 51 patients ( age range 18 to 53 years) with a diagnosis of anteroposterior lesion of the superior glenoid labrum were retrospectively evaluated. MR examinations were performed with a 0.2 T permanent magnet and a dedicated coil, using T1- and T2-weighted SE sequences on mostly coronal-oblique planes. Slice thickness was 4 mm. In 8 cases, the examination was completed with intra-articular injection of contrast agent. Twenty-eight patients were submitted to surgery (arthrotomy in 7 cases; arthroscopy in 21 cases). MRI demonstrated 5 cases of superior labrum irregularities at the level of its glenoid insertional portion (type I lesion); 6 cases of detachment of the superior portion of the labrum (type II); 9 cases of bucket handle tear of the superior labrum with involvement of the insertional portion of the long head of the biceps tendon (type III); 8 cases of superior labrum tear extending within the long head of the biceps tendon (type IV). Subsequent surgery always confirmed the presence of associated lesions, while the superior labrum lesion was not confirmed in 3 patients. In 4 cases, surgical findings provided a different classification of the lesion type than MRI. MRI can be a valuable diagnostic technique in type III and IV lesions of the superior glenoid labrum. It often provides important information about the possible presence of associated diseases, especially of the rotator cuff, which are helpful for treatment planning [it

    Objective was to characterize benign breast diseases in Eastern Nigeria and to highlight the age variations of these lesions as base line data. The Department of Morbid Anatomy, University of Nigeria Teaching Hospital, Enugu caters for over 30 million African blacks and receives 2000 surgical pathology specimens yearly. Seven hundred and twenty-two benign breast specimens were analyzed over 5 years from Ist January 2000 to 31 December 2004, out of 1050 breast samples received. Of 1050 breast specimens received, 722 (68.8%) were benign. Fibroadenoma was the most common lesion with 318 cases (44%), occurring at a mean age of 16-32 years. Next were fibrocystic changes with 165 cases (22.9%) at a mean age of 23-45 years. Normal breast in the axillary tail region was seen in 32 cases (4.4%), represented as no pathology, with a mean presentation age of 20-46 years. Low grade Phyllodes tumor had 28 cases (3.9%), presenting at an average mean age of 17-32 years. Lactating adenoma had 19 (2.6%) cases. Other lesions made up less than 3% each. Benign breast lesions peaked at the 20-24 age range and then declined. Most were females. Benign breast lesions occur more frequently than malignant breast lesions with a ratio of 2.3:1 and were presented 20 years earlier than their malignant counterparts. Fibroadenoma was the most common benign lesions followed by fibrocystic disease, similar to the findings in Western Nigeria. In Northern Nigeria, fibrocystic breast disease was more common. (author)

    Vascular lesions of the uterus are rare; most reported in the literature are arteriovenous malformations (AVMs). Uterine AVMs can be congenital or acquired. In recent years, there has been an increasing number of reports of acquired vascular lesions of the uterus following pregnancy, abortion, cesarean delivery, and curettage. It can be seen from these reports that there is confusion concerning the terminology of uterine vascular lesions. There is also a lack of diagnostic criteria and management guidelines, which has led to an increased number of unnecessary invasive procedures (eg, angiography, uterine artery embolization, hysterectomy for abnormal vaginal bleeding). This article familiarizes readers with various vascular lesions of the uterus and their management. PMID:24340126

    Morphological features of the heart were studied on 34 autopsy cases of malignant tumors treated with x-ray or telecobalt irradiation to the cardiac region. Clinically, 8 cases among 11 with abnormal electrocardiograms had sinus tachycardia. On chest x-ray film, an extension of the median shadow was found in 5 among 26 cases with pericarditis. Histologically, the irradiated heart showed sinus-like capillary dilation in the myocardium and had features of pancarditis; pericarditis fibrinosa, interstitial edema between muscle fibers, myolysis or necrosis, and endocardial edema with slight inflammatory cell infiltration. Radiation pericarditis most often occurred in the case of esophageal carcinoma. Those changes throughout the cardiac wall seem to be directly induced by radiation in addition to circulatory disturbances. Electron-microscopically, there were interesting changes in the mitochondria of cardiac muscles; proliferation and aggregation, fusion of the unit membrane, and an appearance of giant mitochondria up to 3.8 ..mu.. in diameter. In the frequency and extent of both glycoprotein degeneration and myocardial fibrosis, there were no differences between 34 examined and 22 control cases. Fibrosis in the irradiated heart, however, tended to occur in the myocardium just beneath the radiation pericarditis, should be taken into consideration especially in radiotherapeutic cases of esophageal carcinoma.

    Using a microcomputer, the locus and extent of the lesions demonstrated on CT were superimposed on standardized matrices in 127 cases with various types of aphasia, to investigate the relationship between location of the lesions and types of aphasia. Main results were as follows. 1. Broca aphasics: The lesions involved rather large areas in the deep structures of the lower part of the precentral gyrus, the insula and the lenticular nucleus. Therefore, the finding was regarded as being of little localizing value. 2. Wernicke aphasics: At least 70 % of the patients had superior temporal lesions involving Wernicke's area and the subcortical lesions of the superior and middle temporal gyri. The site of the lesion corresponded roughly with that in the previous clinico-pathological reports but was indicated in a little deeper area. 3. Amnestic aphasics: The size of the lesion was smaller than any other type but the lesions were distributed throughout the left hemisphere. Amnestic asphasia was thought to be the least localizable. 4. Conduction aphasics: Most patients had lesions in the posterior speech area involving part of Wernicke's area. In particular, in more than 80 % of the conduction aphasics the lesions were revealed in the supramarginal gyrus and it's adjacent deep structures. 5. Global aphasics: In general, the size of the lesion was very large and 70 % of the global aphasics had extensive lesions involving both Broca's and Wernicke's areas. However, there were some patients showing small and confined lesions. (author)

    Full Text Available Benign fibroosseous lesions represent a group of lesions that share the same basic evolutive mechanism and are characterized by replacement of normal bone with a fibrous connective tissue that gradually undergoes mineralization. These lesions are presented by a variety of diseases including developmental, reactive-dysplastic processes and neoplasms. Depending on the nature and amount of calcified tissue, they can be observed as radiolucent, mixed or radiopaque. Their radiographic features could be well-defined or indistinguishable from the surrounding bone tissue. They can be asymptomatic as in osseous dysplasias and can be detected incidentally on radiographs, or they can lead to expansion in the affected bone as in ossifying fibroma. All fibroosseous lesions seen in the jaws and face are variations of the same histological pattern. Therefore, detailed clinical and radiographic evaluation in differential diagnosis is important. In this review, fibroosseous benign lesions are classified as osseous dysplasia, fibrous dysplasia and fibroosseous tumors; and radiographic features and differential diagnosis of these lesions are reviewed taking into account this classification.

    Full Text Available Abstract Background Fragmented QRS (fQRS complexes are novel electrocardiographic signals, which reflect myocardial conduction delays in patients with coronary artery disease (CAD. The importance of fQRS complexes in identifying culprit vessels was evaluated in this retrospective study. Methods A 12-lead surface electrocardiogram was obtained in 183 patients who had non-ST-elevation myocardial infarction (NSTEMI and subsequently underwent coronary angiography (CAG. On the basis of the frequency of fQRS complexes, indices such as sensitivity, specificity, positive and negative predictive values, and likelihood ratio were evaluated to determine the ability of fQRS complexes to identify the culprit vessels. Results Among the patients studied, elderly patients (age ≥ 65 years and those with diabetes had a significantly higher frequency of fQRS complexes (p = 0.005, p = 0.003, respectively. The fQRS complexes recorded in the 4 precordial leads had the highest specificity (81.8% for indentifying the culprit vessel (left anterior descending artery. However, the specificity of fQRS complexes to identify lesions in the left circumflex and right coronary arteries was lower for the inferior and lateral leads than for the limb leads (65.5% versus 71.7%; however, the limb leads had higher sensitivity (92.3% versus 89.4%. And the total sensitivity and specificity of fQRS (77.1% and 71.5% were higher than those values for ischemic T-waves. Conclusions The frequency of fQRS complexes was higher in elderly and diabetic patients with NSTEMI. The frequency of fQRS complexes recorded in each of the ECG leads can be used to identify culprit vessels in patients with NSTEMI.

    Although plain computerized axial tomography cannot routinely demonstrate the spinal cord, it does provide excellent visualization of the bony outline of the spinal canal and vertebral column. So it should be reasonable to use this technique in cases of cervical traumatic disorders. In this paper we presented 10 cases of cervical traumatic lesions; 3 atlanto-axial dislocation, 2 cervical canal stenosis, 3 OPLL, 1 intramedullary hematoma and 1 C 2 -neurinoma. In some patients neurologic deficits were induced by cervical trauma. Bony lesions appeared more adequately deliniated than intraspinal lesions, however, in some cases intramedullary changes could also be demonstrated. The use of metrizamide with high resolution CT-scanner could improve the usefullness of this technique. (author)

    Authors retrospectively analyzed ultrasonographic findings of 61 cases of breast lesions which were proven pathologically at Daerim St. Mary's Hospital from May 1987 to February 1990. The results were as follows : 1. Of all 61 cases, there were 27 fibroadenomas, 13 fibrocystic diseases, 11 carcinomas, 8 abscesses, 1 sclerosing adenosis, and 1 intraductal papilloma. 2. Findings suggesting benignancy were smooth contour, round or oval shape, homogeneously echolucent internal echo, echogenic boundary echo, and posterior enhancement. In the cases of abscess, the findings were rather irregular contour, strong posterior enhancement, and dirty, inhomogeneous internal echo. While irregular and lobulated shape, inhomogeneous and mixed internal echo and pectoral muscle invasion were suggested for malignancy. 3. The sensitivity was 98% and the specificity 58% in benign mass excluding abscesses, 63% and 98% in abscesses, and 55% and 98% in carcinomas. In conclusion, ultrasonography is one of the excellent imaging modality for detecting breast lesions larger than 5 mm in size, but unfortunately some of the malignant tumors simulated benignancy, thus we considered fine needle aspiration biopsy and adjunctive imaging modalities such as film mammography must be followed for better detection of breast cancer

    Full Text Available There are several reports of central pontine myelinolysis (CPM in a setting of malnutrition, alcoholism, and chronic debilitating illness associated with electrolyte abnormalities, especially hyponatremia. The cause of myelinolysis is still under debate, and, although osmotic effects are thought to be responsible in most cases, alternative pathological factors should be considered [King et al.: Am J Med Sci 2010;339:561–567]. We report a case of CPM in a patient with recent chemotherapy for colon cancer without electrolyte unbalance and otherwise unexplained causes. Moreover, the present case is an example of the unusual clinical ataxic variant, followed by complete recovery without any specific treatment. The diagnosis was confirmed by MRI, which showed a characteristic hyperintense signal abnormality in the central part of the pons with an unaffected outer rim. One month later, we observed complete resolution of clinical and radiological symptoms.

    To evaluate the correlation of lesions of the brain as visualized in cranial magnetic resonance imaging (MRI) and the ability of spontaneous respiration. In a prospective concept, cranial MRI after traumatic brain injury or spontaneous intracerebral hemorrhage was performed in 250 subjects at an early stage. All MRI findings were correlated with respiratory conditions on the day of examination. Sedation was performed only to facilitate toleration of the artificial ventilation, as and when necessary. Spontaneous respiration could hence be registered clinically. Thirteen subjects (5.2%) had no spontaneous respiration. In these cases, a bilateral lesion of the distal medulla oblongata could be displayed. In four of these cases, no additional injuries of the brainstem were detected. These subjects awoke 2 days after the impact with tetraparesis and apnea. Combined lesions of the medulla oblongata and other brainstem regions were found in nine subjects. All these patients died without awakening. In the absence of a bilateral lesion of the caudal medulla oblongata, spontaneous respiration was always possible. A unilateral lesion of the caudal medulla oblongata was visualized in one patient who had the ability of spontaneous respiration. This work confirms the presence of autonomous respiratory centers within the caudal medulla oblongata that allows sufficient adequate respiration in coma. Respiration ceases in the presence of a bilateral lesion of this area.

    The posterior urethral lesions are associated with pelvis fractures in 5-10% of cases. The posterior urethra is attached to the pelvis bone by puboprostatic ligaments and the perineal membrane, which explains why disruption of the pelvic ring can injure the urethra at this level. To identify suspected cases of posterior urethral trauma and to perform the diagnosis and its immediate or deferred management. Search in PubMed of articles related to traumatic posterior urethral lesions, written in English or Spanish. We reviewed the relevant publications including literature reviews and chapters from books related to the topic. With patients with pelvis fractures, we must always rule out posterior urethral lesions. The diagnostic examination of choice is retrograde urethrography, which, along with the severity of the condition, will determine the management in the acute phase and whether the treatment will be performed immediately or deferred. Early diagnosis and proper acute management decrease the associated complications, such as strictures, urinary incontinence and erectile dysfunction. Despite the classical association between posterior urethral lesions and pelvic fractures, the management of those lesions (whether immediate or deferred) remains controversial. Thanks to the growing interest in urethral disease, there are an increasing number of studies that help us achieve better management of these lesions. Copyright © 2016 AEU.

    1994-09-01

    Laparoscopic cholecystectomy is both resulting in a slightly higher incidence of biliary lesions and a change of prevalence of the type of lesions. Damage to the biliary system occurs in 4 different types: The most severe case is the lesion with a structural defect of the hepatic or common bile duct with (IVa) or without (IVb) vascular injury. Tangential lesions without structural loss of the duct should be denominated as type III (IIIa with additional lesion to the vessels, type IIIb without). Type II comprehends late strictures without obvious intraoperative trauma to the duct. Type I includes immediate biliary fistulae of usually good prognosis. The increasing prevalence of structural defects of the bile ducts appears to be a peculiarity of laparoscopic cholecystectomy necessitating highly demanding operative repair. In the majority of cases, hepatico-jejunostomy or even intraparenchymatous anastomoses are required. Adaptation of well proven principles of open surgery is the best prevention of biliary lesions in laparoscopic cholecystectomy as well as the readiness to convert early to the open procedure.

    Conclusion: The most critical aspect of the evaluation of metastatic cases is the accurate pathologic assessment of the malignant tissues in conjunction with pertinent clinical data. Such close collaboration between the clinician and the pathologist may maximize the diagnostic potential in treatable primary tumors.

    Full Text Available BACKGROUND Papulosquamous lesions form the largest group of skin diseases. Since, they are all characterized by scaling papules or plaques, clinical confusion may result in their diagnosis, hence definitive histopathological analysis is important for their differentiation. MATERIALS AND METHODS The study includes skin biopsies from 108 clinically diagnosed /suspected non-infectious, erythematous, papulosquamous skin diseases which were received in the Department of Pathology, Andhra Medical College, Visakhapatnam for a period of two years from January 2016 to December 2017. The specimens obtained were subjected to formalin fixation and was subjected to routine processing and sections were stained with haematoxylin and eosin (H&E. The lesions were classified as Lichen Planus, Psoriasis, along with rare conditions like Pityriasis Rosea, Parapsoriasis, Pityriasis Rubra Pilaris, Prurigo Nodularis and Lichen Simplex chronicus and clinicopathological correlation was done. RESULTS A total of 108 cases were studied. Lichen planus (51 cases- 47.22% was the most common lesions followed by Psoriasis (34 cases - 31.48% and with majority of cases in the age group of 21 to 30 years (25 cases– 23.15%. Females were more commonly affected with a male to female ratio of 0.89:1. Out of 108 cases, clinicopathological correlation was seen in 68 cases (62.96%. CONCLUSION The importance of specific histopathological diagnosis lies in distinguishing these lesions into different entities as the treatment and prognosis varies widely and is disease-specific.

    To compare the concordance between fine-needle aspiration and core biopsies for osseous lesions by lesion imaging appearance and CT attenuation. Retrospective review of 215 FNAs of osseous lesions performed in conjunction with core biopsy at our institution over a 6-year period (2011-2016). FNAs were interpreted independently of core biopsies. We assessed if FNA in conjunction with core biopsy increased diagnostic accuracy compared to core biopsy alone. We also calculated the concordance between FNA and core biopsy by lesion appearance, lesion CT attenuation, lesion histology, lesion location and FNA needle gauge size. Core biopsy alone provided the diagnosis in 207/215 cases (96.3%), however, the FNA provided the diagnosis in the remaining 8/215 cases (3.7%) where the core biopsy was non-diagnostic. There were 154 (71.6%) lytic lesions, 21 (9.8%) blastic lesions, 25 (11.6%) mixed lytic and blastic lesions and 15 (7.0%) lesions that were neither lytic nor blastic. The concordance between FNA and core biopsy for lytic osseous lesions (136/154 cases, 88.3%) was statistically significantly higher than that for blastic osseous lesions (13/21 cases, 61.9%) [P = 4.2 × 10 -3 ; 95% CI (0.02, 0.50)]. The concordance between FNA and core biopsy was higher for low-attenuation- (110/126) than high-attenuation (58/77) lesions (P = 0.028). The concordance between FNA and core biopsy was also higher for metastases (102/119 cases, 85.7%) than non-metastases (78/96, 81.3%) [P = 0.487; 95% CI (- 0.15, 0.065)]. There was no difference in the rate of concordance between FNA and core biopsy by lesion location or FNA needle gauge size (P > 0.05). FNA with core biopsy increases diagnostic rate compared to core biopsy alone or FNA alone. The concordance between FNA and core biopsy is higher for lytic lesions than for blastic lesions; and higher for low-attenuation lesions than for high-attenuation lesions.

    The incidence of osteochondral lesions (OCLs) in association with displaced ankle fractures has only been examined in two previous studies. In both studies magnetic resonance imaging (MRI) was performed prior to open reduction and internal fixation (ORIF). Because MRI may overdiagnose or overestimate the extent of OCLs in an acute trauma setting the aim of this study was to determine the incidence of OCLs after ORIF of displaced ankle fractures using MRI at medium-term follow-up, and to analyse if the severity of fracture or the clinical outcome correlates with the incidence of OCLs. Following institutional review board approval a total of 100 patients (mean age, 41.3 years; range, 17.9-64.3 years) with a displaced ankle fracture who had undergone ORIF according to the AO principles were included in this study. The American Orthopaedic Foot and Ankle Society (AOFAS) hindfoot score was used to quantify the clinical outcome and MR images were evaluated for OCLs of the talus and distal tibia after a mean of 34.5 months (range, 17.5-54.1 months). OCLs were found in 40.4% of the patients. Logistic regression revealed a significant correlation between the severity of fracture and the incidence of OCLs. Patients with a trimalleolar fracture (p=0.04) or an ankle fracture dislocation (p=0.003) had a significantly higher risk for developing an OCL compared to those with a type B fracture. Logistic regression also demonstrated a significant correlation between the clinical outcome (AOFAS score) and the incidence of OCLs (p=0.01). The risk for developing an OCL increases up to 5.6% when the AOFAS score decreases by one point. OCLs were frequently found in association with acute ankle fractures at medium-term follow-up, and the severity of fracture was associated with an increased number of OCLs. Considering the disadvantages of MRI including the high cost and limited availability, the results of this study may help to explain why anatomic surgical realignment of displaced

    We aimed to evaluate nonendodontic periapical lesions clinically misdiagnosed as endodontic periapical pathoses in a population of Taiwanese patients. Cases (2000-2014) of histopathological diagnoses of nonendodontic periapical lesions were retrieved from all cases with a clinical diagnosis of radicular cyst, apical granuloma, or apical periodontitis in the institution. These cases were regarded as misdiagnosed nonendodontic periapical lesions, of which the types and frequencies, in addition to the demographic data, were determined. Four thousand and four specimens were clinically diagnosed as endodontically associated pathoses, of which 118 cases (2.95%) received a histopathological diagnosis of a nonendodontic pathologic entity, the most frequent lesion being keratocystic odontogenic tumor (KCOT, n = 38, 32.20%), followed by fibro-osseous lesion (n = 18, 15.25%), and dentigerous cyst (n = 13, 11.02%). Nine malignant lesions in the periapical area [squamous cell carcinoma (n = 7, 5.93%), adenoid cystic carcinoma (n = 1, 0.85%), and Langerhans cell histiocytosis (n = 1, 0.85%)] were also noted. A wide variety of histopathological diagnoses, including benign odontogenic and non-odontogenic cystic and tumorous lesions and infectious diseases, as well as malignant lesions, was noted in these 118 cases of nonendodontic periapical lesions. Squamous cell carcinoma was the most predominant malignancy of nonendodontic periapical lesions misdiagnosed as apical periodontitis lesions from imaging examination overlooking the clinical findings. The current data form a useful basis for clinicopathological investigation and educational teaching regarding nonendodontic periapical lesions misdiagnosed as endodontic apical periodontitis lesions.

    Full Text Available Regenerative endodontics is the creation and delivery of tissues to replace diseased, missing, and traumatized pulp. A call for a paradigm shift and new protocol for the clinical management of these cases has been brought to attention. These regenerative endodontic techniques will possibly involve some combination of disinfection or debridement of infected root canal systems with apical enlargement to permit revascularization and use of stem cells, scaffolds, and growth factors. Mesenchymal stem cells (MSCs have been isolated from the pulp tissue of permanent teeth (dental pulp stem cells (DPSCs and deciduous teeth (stem cells from human exfoliated deciduous teeth. Stem cells are characterized as multipotent cells for regeneration.These three case reports describe the treatment of necrotic or immature teeth with periradicular periodontitis, which was not treated with conventional apexification techniques. All cases presented here developed mature apices and bone healing after 3 to 4 months after the initial treatment without complications, and faster than traditional treatments. Our clinical observations support a shifting paradigm toward a biologic approach by providing a favorable environment for tissue regeneration. The mechanism of this continued development and formation of the root end and faster tissue healing is discussed.

    2012-01-01

    Full Text Available Background and Objectives: To assess the diagnostic capability of real-time ultrasound imaging, together with the application of color power Doppler in the identification and differential diagnosis of the periapical lesions. Materials and Methods: Fifteen patients with periapical lesions of pulpal origin, diagnosed with clinical and conventional radiographic examination, were examined further using ultrasonography. The results from the biopsies of the lesions were compared and statistically analyzed. Results: The differential diagnosis between periapical granulomas and cystic lesions, which were based on the ultrasonographic findings, were confirmed by the results of the histopathologic examination in 13 (86.7% of 15 cases, one being granuloma and 14 being cystic lesion. Interpretation and Conclusion: Ultrasound real-time imaging is a technique that may help make a differential diagnosis between cysts and granulomas by revealing the nature of the content of a bony lesion. This technique may have further applications in the study of other lesions of the jaws.

    Full Text Available A primipara presented to our hospital due to fetal ascites, bilateral hydronephrosis and hydrometrocolpos. The female baby had two giant abdominal cysts, a single atrium and foot polydactyly. Absence of the vaginal orifice was noticed, and the hymen was broken through; the left cyst collapsed after fluid drainage. The right cyst was punctured and drained, which improved the hydronephrosis. Contrast imaging showed medium pouring into the abdominal cavity via the uterine tube; the right cyst was a 6 × 5 cm closed cavity. Vaginal uroplania persisted even after hospital discharge. At the age of 4 years, cystoscopy showed a fistulous opening on the urethra 5 mm distal from the internal urethral orifice. A catheter inserted via the opening was found in the vagina. In our case, urine poured into the abdominal cavity through the fistula and uterine tube; following obstruction of the uterine tube, giant hydrometrocolpos and hydrosalpinx appeared. Three cases of congenital urethrovaginal fistula (CUVF with imperforate hymen have been reported. A remnant of communication between the uterovaginal primordium and urogenital sinus may be responsible for CUVF.

    Focal cortical dysplasia (FCD) is a pathological entity first described in 1971. Other more subtle cortical malformations found in patients with epilepsy include microdysgenesis (MD), and glioneuronal hamartias. Although these glial and neuronoglial malformations have distinct histological features, there is terminological confusion in the radiological literature. Few cases have been reported in adults with both imaging and histology. We address these issues, giving a radiological-pathological correlation of histologically proven cortical malformations in adults. We describe clinical, radiological and histological features of 12 cases (five FCD, five MD with glioneuronal hamartias, and two hamartomas), unassociated with other conditions, and discuss them in the light of the literature. FCD is usually seen on MRI as cortical thickening, with or without signal change, which may extend into the adjacent white matter. On histology, abnormal neurons and/or glial cells, blurring of the grey-white matter interface, myelin pallor, demyelination, and gliosis may be found. Glioneuronal hamartias and hamartomas usually appear as complex masses on MRI. FCD and hamartias may be associated, and a combination of imaging findings may be seen on MRI. Atrophy of the ipsilateral hippocampus may be present on MRI in patients with hamartias, and minor cell loss on histology, but not definitive hippocampal sclerosis. Although the imaging findings of cortical malformations are protean, some characteristic MRI features, with histological correlates, may be found. The relevance of most of these observations remains unclear. (orig.)

    Adjacent natural teeth with untreated pulpal or periodontal pathology may be a potential risk for implant infection. We report a rare case of an implant periapical lesion (IPL) possibly caused by direct extension of a periradicular lesion of an adjacent tooth. A 40-year-old female patient, who had previously received three implants on the edentulous areas of teeth 16, 36 and 46, had a recurrent infection over the lower left second molar area for 2 years. A periapical radiograph revealed incom...

    Fever of unknown origin (FUO) remains one of the most difficult diagnostic challenges. The causes of FUO can be various diseases located in different organs. The aim of the study was to determine the prevalence and nature of pulmonary lesions during FUO. One hundred and sixty one patients with FUO participated in this prospective study. We performed a detailed comprehensive history, physical examination, and a wide spectrum of tests. The most common causes of FUO were infections (39%), autoimmune conditions (28%), and neoplasms (17%). Lung lesions were found in 30% of patients. In this group 35% were infections, 30% autoimmune diseases, and 4% cancer. Among patients with respiratory infections, there were cases of tuberculosis, atypical pneumonia, lung abscess, and bronchiectases. Autoimmune pulmonary lesions were observed during vasculitis and systemic lupus. The causes of FUO in the group of patients with lung lesions were also pulmonary embolism, sarcoidosis, and pulmonary fibrosis. Chest CT played an important role in the diagnosis of the causes of FUO with pulmonary manifestations. Pulmonary lesions are a common cause of FUO. Most FUO with pulmonary lesions are recognized during infections and autoimmune diseases. An important part of diagnosing FUO is a detailed evaluation of the respiratory system.

    Full Text Available BACKGROUND: Surgical treatment of odontogenic jaw cysts may include one of the following four basic methods: enucleation, marsupialization, staged combination of marsupialization and enucleation, or enucleation with curettage. Enucleation/cystectomy, alone or combined with other procedures, is the preferred choice of treatment. OBJECTIVE: The aim of the case report was to present the outcome of an ultrasound-assistant periapical cystectomy in a frontal upper tooth with indications for extraction. RESULTS: Postoperative recovery was uneventful. The functional result was satisfactory. On the follow-up X-rays a reduction of the intraosseous defect by a new bone formation could be observed. CONCLUSION: We found ultrasonic surgery to be a promising approach for safe and effective odontogenic jaw cyst removal reducing the risk of its recurrence.

    To review current knowledge of the Morel-Lavallee lesion (MLL) to help clinicians become familiar with this entity. Familiarization may decrease missed diagnoses and misdiagnoses. It could also help steer the clinician to the proper treatment choice. A search was performed via PubMed and EMBASE from 1966 to July 2013 using the following keywords: Morel-Lavallee lesion, closed degloving injury, concealed degloving injury, Morel-Lavallee effusion, Morel-Lavallee hematoma, posttraumatic pseudocyst, posttraumatic soft tissue cyst. Chinese and English language literatures relevant to the subject were collected. Their references were also reviewed. Morel-Lavallee lesion is a relatively rare condition involving a closed degloving injury. It is characterized by a filled cystic cavity created by separation of the subcutaneous tissue from the underlying fascia. Apart from the classic location over the region of the greater trochanter, MLLs have been described in other parts of the body. The natural history of MLL has not yet been established. The lesion may decrease in volume, remain stable, enlarge progressively or show a recurrent pattern. Diagnosis of MLL was often missed or delayed. Ultrasonography, computed tomography, and magnetic resonance imaging have great value in the diagnosis of MLL. Treatment of MLL has included compression, local aspiration, open debridement, and sclerodesis. No standard treatment has been established. A diagnosis of MLL should be suspected when a soft, fluctuant area of skin or chronic recurrent fluid collection is found in a region exposed to a previous shear injury. Clinicians and radiologists should be aware of both the acute and chronic appearances to make the correct diagnosis. Treatment decisions should base on association with fractures, the condition of the lesion, symptom and desire of the patient.

    Mammary-type myofibroblastoma is a very rare, benign mesenchymal tumor consisting of spindle-shaped cells along with thick hyalinized collagen bundles and an intralesional fat component; its histopathological features are identical to those of myofibroblastomas of the breast. It usually occurs along the embryonic milk-line; however, unusual cases occurring outside of the embryonic milk-line have also been reported. Although this tumor always shows clinically benign behavior, its variable histological composition can easily be confused with many other fibrous and lipomatous neoplasms. Unfortunately, its radiological findings are extremely rarely described in the literature. Here, we present a rare case of mammary-type myofibroblastoma in a 38-year-old woman who presented with a well-circumscribed solitary mass in the buttock, and discuss various radiologic imaging findings, such as plain radiography, ultrasonography, and magnetic resonance imaging results.

    To compare virtual gastroscopy using spiral CT with conventional endoscopy for the detection and evaluation of gastric lesions. During a previous six-month period, 30 patients with pathologically-proven gastric lesions underwent conventional endoscopy and virtual gastroscopy using spiral CT. There were 18 cases of advanced gastric carcinoma, eight benign ulcers, and four submucosal tumors(two leiomyomas, two lymphomas). Source images of virtual gastroscopy were three-dim-ensionally reconstructed within an Advantage Windows Workstation and virtual gastroscopic images were obtained using Navigator Software. On analysis, images were graded according to their quality(excellent, good, poor). Virtual gastroscopic images were interpreted by two radiologists blinded to conventional endoscopic findings, and were subsequently compared with endoscopic findings in terms of detectability and findings. In the cases of advanced gastric carcinoma, lesions were classified according to Borrmann's system. For virtual gastroscopy, overall image quality was excellent in 21 cases(70%), good in five(17%), and poor in four(13%). Lesions were detected in 25 cases(83%). Among the 18 advanced gastric carcinomas, virtual gastroscopy image quality was excellent in 14 cases(78%), good in two(11%), and poor in two(11%). Lesions were detected in 16 cases(89%). Two Borrmann type IV cases were not detected. Among the eight benign ulcers, virtual gastroscopy image quality was excellent in three cases(38%), good in three(38%), and poor in two(25%). The detection of lesion was possible in five cases(63%). In all submucosal tumors, virtual gastroscopy image quality was excellent. Lesions were detected in all cases. Virtual gastroscopy using spiral CT is safe and noninvasive, and for the evaluation of gastric lesions may be complementary to axial CT. It successfully detects gastric lesions, and in depicting the pattern of gastric folds its image quality is excellent.=20

    1999-01-01

    OBJECTIVES—Global aphasia without hemiparesis (GAWH) is an uncommon stroke syndrome involving receptive and expressive language impairment, without the hemiparesis typically manifested by patients with global aphasia after large left perisylvian lesions. A few cases of GAWH have been reported with conflicting conclusions regarding pathogenesis, lesion localisation, and recovery. The current study was conducted to attempt to clarify these issues.
METHODS—Ten cases of GAWH were prospectively studied with language profiles and lesion analysis; five patients had multiple lesions, four patients had a single lesion, and one had a subarachnoid haemorrhage. Eight patients met criteria for cardioembolic ischaemic stroke.
RESULTS—Cluster analysis based on acute language profiles disclosed three subtypes of patients with GAWH; these clusters persisted on follow up language assessment. Each cluster evolved into a different aphasia subtype: persistent GAWH, Wernicke's aphasia, or transcortical motor aphasia (TCM). Composite lesion analysis showed that persistent GAWH was related to lesioning of the left superior temporal gyrus. Patients with acute GAWH who evolved into TCM type aphasia had common lesioning of the left inferior frontal gyrus and adjacent subcortical white matter. Patients with acute GAWH who evolved into Wernicke's type aphasia were characterised by lesioning of the left precentral and postcentral gyri. Recovery of language was poor in all but one patient.
CONCLUSIONS—Although patients with acute GAWH are similar on neurological examination, they are heterogeneous with respect to early aphasia profile, language recovery, and lesion profile.

    The iliopsoas compartment, a posterior boundary of the retroperitoneum, is comprised of the psoas major, psoas minor and iliac muscles. The symptoms picture in patients presenting with pathological involvement of this compartment may show a wide range of nonspecific clinical presentations that may lead to delayed diagnosis. However, in the search of an etiological diagnosis, it is already known that inflammation, tumors, and hemorrhages account for almost all the lesions affecting the iliopsoas compartment. By means of a retrospective analysis of radiological studies in patients with iliopsoas compartment lesions whose diagnosis was confirmed by anatomopathological evaluation or clinical follow-up, we have reviewed its anatomy as well as the main forms of involvement, with the purpose of identifying radiological signs that may help to narrow down the potential differential diagnoses. As each lesion is approached we will discuss the main radiological findings such as presence of gas in pyogenic abscesses, bone destruction and other bone changes of vertebral bodies in lesions secondary to tuberculosis, involvement of fascial planes in cases of neoplasms, and differences in signal density and intensity of hematomas secondary to hemoglobin degradation, among others. So, we have tried to present cases depicting the most frequent lesions involving the iliopsoas compartment, with emphasis on those signs that can lead us to a more specific etiological diagnosis.

    Here we report a case in which a locally advanced ascending colon cancer was successfully treated with anti-EGFR immunotherapy combined with chemotherapy and curative resection, and recurrent cancer was treated with the same chemotherapy. A 71-year-old man was diagnosed with ascending colon cancer in our department. No distant metastasis was observed, but curative resection was considered impossible because of extensive local cancer invasion. Because a genetic analysis revealed the presence of the wild-type KRAS gene, 6 courses of mFOLFOX6 plus cetuximab were administered. A cPR was obtained and curative resection was performed. The final diagnosis was ypT3N1M0, ypStage III a colon cancer, and chemotherapy improved the cancer stage to Grade 1b. Six courses of FOLFOX6 were then administered, followed by observation. After 2 years 6 months, a tumor of approximately 5 cm in size was noted in the right buttock using surveillance CT and was diagnosed as recurrent colon cancer. We considered further curative resection difficult and therefore 6 courses of mFOLFOX6 plus panitumumab were administered, a cPR was obtained, and right hip tumor extirpation surgery was performed. These results suggest that chemotherapy combined with anti-EGFR antibody immunotherapy is effective in treating recurrent colon cancer.

    To evaluate the nature and imaging appearance of incidental enhancing breast lesions detected on a routine contrast-enhanced chest CT. Twenty-three patients with incidental enhancing breast lesions on contrast-enhanced chest CT were retrospectively reviewed. The breast lesions were reviewed by unenhanced and enhanced CT, and evaluated by observing the shapes, margins, enhancement patterns and backgrounds of breast lesions. A histopathologic diagnosis or long-term follow-up served as reference standard. Sixteen (70%) patients had malignant breast lesions and seven (30%) had benign lesions. In 10 patients, the breast lesions were exclusively detected on contrast-enhanced CT. Using unenhanced CT, breast lesions with fi broglandular backgrounds were prone to be obscured (p < 0.001). Incidental primary breast cancer showed an non-significant trend of a higher percentage irregular margin (p = 0.056). All of the four incidental breast lesions with non-mass-like enhancement were proven to be malignant. Routine contrast-enhanced chest CT can reveal sufficient details to allow for the detection of unsuspected breast lesions, in which some cases may be proven as malignant. An irregular margin of incidental enhancing breast lesion can be considered a suggestive sign of malignancy

    Our aim is to illustrate the contribution of MRI to diagnosis of lesions of the lower-limb nerve trunks. We report six patients who had clinical and electrophysiological examination for a peroneal or tibial nerve palsy. MRI of the knee showed in three cases a nonenhancing cystic lesion of the peroneal nerve suggesting an intraneural ganglion cyst, confirmed by histological study in one case. One patient with known neurofibromatosis had an enhancing nodular lesion of the peroneal nerve compatible with a neurofibroma. Two patients had diffuse hypertrophy with high signal on T2-weighted images, without contrast enhancement of the sciatic nerve or its branches. These lesions were compatible with localised hypertrophic neuropathy. In one case, biopsy of the superficial branch of the peroneal nerve showed insignificant axonal degeneration. MRI can provide information about the size and site of the abnormal segment of a nerve before treatment and can be used to distinguish different patterns of focal lesion. (orig.)

      The purpose of the present study was to evaluate the correlation between clinical and histopathological diagnoses of periapical inflammatory lesions, focusing mainly on cystic conditions.   Files dating from 1998 to 2006 at the Oral Pathology Laboratory, School of Dentistry, Alfenas Federal University, Brazil, were reviewed to identify cases with histopathological diagnoses of periapical inflammatory lesions. A total of 1788 files were analyzed, and 255 cases were identified with clinical diagnoses of periapical inflammatory lesions.   The most prevalent clinical diagnosis was apical periodontal cyst (59%), followed by periapical granuloma (20%), and dentoalveolar abscess (2%). After histopathological analysis, 53% of the cases represented apical periodontal cyst, 42% periapical granuloma, and 5% dentoalveolar abscess.   The outcomes of the present study show a high prevalence of periapical cysts among periapical inflammatory lesions. Moreover, this study highlights the importance of histopathological evaluation for the correct diagnosis of periapical inflammatory lesions. © 2011 Blackwell Publishing Asia Pty Ltd.

    Full Text Available Ureteritis cystica is an uncommon benign pathology of the ureter. The etiology is unclear but the diagnosis has become much easier to make with the routine use of ureteroscopy for diagnosis of ureteric lesions. We present a case of a 63 year old Sudanese woman with a history of repeated attacks of right loin pain in whom magnetic resonance urography (MRU showed multiple filling defects in the right ureter. These were initially thought to be malignant urothelial lesions. Ureteroscopy revealed cystic smooth walled masses which discharged tiny turbid fluid on biopsy. An intraoperative diagnosis of ureteritis cystica was confirmed. The patient was managed conservatively.

    Only a few studies have been reported on the MR contrast enhancement and the apparent diffusion coefficient (ADC) findings of the post-traumatic lesion of the brain. We report a case of the venous ischemia in the left frontal lobe observed in the MRI obtained one day after the incidence of trauma. Considering the presented slight increase in the ADC, the vasogenic edema was thought to be the major mechanism of the venous ischemia and excitotoxic injury. In spite of a slight increase in the ADC, the hyperintensity in the diffusion weighted imaging and contrast-enhanced areas eventually changed into hemorrhagic lesions.

    CT was undertaken and CT numbers were measured in 47 patients with cystic ovarian lesions. CT features particularly for chocolate cyst revealed the uniform thickness of the whole cystic wall, findings suggesting adhesion to the surrounding organs, circular or oval shape, and higher CT numbers within the cyst than those in the other cystic ovarian lesions. However, because these features are not always observed in cases of chocolate cyst, one should not rely solely on CT findings in the diagnosis of chocolate cyst. (Namekawa, K.)

    Pathology in both cortex and deep gray matter contribute to disability in multiple sclerosis (MS). We used the increased signal-to-noise ratio of 7-tesla (7T) MRI to visualize small lesions within the thalamus and to relate this to clinical information and cortical lesions. We obtained 7T MRI scans on 34 MS cases and 15 healthy volunteers. Thalamic lesion number and volume were related to demographic data, clinical disability measures, and lesions in cortical gray matter. Thalamic lesions were found in 24/34 of MS cases. Two lesion subtypes were noted: discrete, ovoid lesions, and more diffuse lesional areas lining the periventricular surface. The number of thalamic lesions was greater in progressive MS compared to relapsing-remitting (mean ±SD, 10.7 ±0.7 vs. 3.0 ±0.7, respectively, p < 0.001). Thalamic lesion burden (count and volume) correlated with EDSS score and measures of cortical lesion burden, but not with white matter lesion burden or white matter volume. Using 7T MRI allows identification of thalamic lesions in MS, which are associated with disability, progressive disease, and cortical lesions. Thalamic lesion analysis may be a simpler, more rapid estimate of overall gray matter lesion burden in MS. © The Author(s), 2015.

    The purpose of this study was to evaluate the clinical usefulness of dynamic multislice helical CT in differentiating ameloblastoma from other cystic lesions in cases of maxillomandibular cystic lesions. The study included 32 patients with maxillomandibular cystic lesions (ameloblastoma [n=6], myxofibroma [n=1], odontogenic keratocyst [n=3], dentigerous cyst [n=11], radicular cyst [n=11], and paradental cyst [n=2]). Dynamic study was performed before and 30 sec, and 90 sec after intravenous contrast medium administration. CT density values and percentage of density increase were calculated at 30 and 90 sec. In five cases of ameloblastoma, a rapidly enhancing area was detected within the cystic lesions at 30 sec, while no apparent rapid enhancement was seen in the other cystic lesions. Three cysts showed gradual enhancement in the marginal area at 90 sec. Comparing ameloblastoma and other kinds of cysts, we found significant differences in the percentage of density increase at 30 sec (p<0.01) and 90 sec (p<0.05). Dynamic multislice helical CT is useful in the diagnosis of cystic lesions of the maxillomandibular region, especially in the detection of neovascularities in ameloblastoma. (author)

  16. Roentgenologic diagnostics of capsular ligament lesions

    The X-ray diagnostic is of obvious importance and relevance in the detection of acute or old capsular ligament lesions of the limb joint. On the one hand it serves as the plain radiograph (roentgenogram without contrast medium) for the assessment of osseous secondary lesions, for the documentation of luxationary positions of the joint partners, and in old capsular ligament lesions for the detection of an already existing arthrosis. On the other hand the X-ray images are of main importance, which are made from the hand-held limb in order to permit a comparison of the two sides, and which beyond the clinical detection of a joint instability indicate the extent and the direction of this instability and which also document it, and which allow in adolescents to recognize a separation of the epiphysis as an alternative to the capsular ligament rupture. Only in particular cases arthrography can provide some additional information, so for example in the case of an isolated syndesmosis rupture, ruptures of the rosette of the rotator muscle or of a damaged triangular disk in the hand. Angiography is only required in cases of traumatic luxations of the knee in order to exclude an intimal lesion of the popliteal artery.

    Neutropenic patients developing acute disseminated candidiasis may present with skin lesions. To evaluate the epidemiology of acute disseminated candidiasis with skin lesions in neutropenic patients, taking into consideration changes caused by different prophylactic strategies. A systematic review of English-language articles found via PubMed (1963-2016) was performed. We asked the following questions: (a) What Candida species are more frequently involved in this syndrome? (b) Has antifungal prophylaxis changed the species causing skin lesions? (c) What are the typical patterns of skin lesions? (d) What is the frequency of skin lesions in neutropenic patients with candidaemia or acute disseminated candidiasis? (e) Has antifungal prophylaxis decreased the incidence of acute disseminated candidiasis with skin lesions? Among 183 studies, 33 were selected, reporting 100 cases of acute disseminated candidiasis with skin lesions in neutropenic patients. It occurred more frequently in the setting of induction therapy for de novo or relapsed acute leukaemia, and the most frequent Candida species were C. tropicalis (68%) and C. krusei (15%). Diffuse maculopapular lesions predominated in cases caused by C. tropicalis and nodular and papular lesions in cases caused by C. krusei. Prophylaxis with fluconazole was reported in six cases, C. krusei in five and C. ciferrii in one. The death rate was 45.4%. Two patterns were recognized: disseminated maculopapular lesions caused by C. tropicalis in patients not receiving fluconazole prophylaxis, occurring in 39% to 44% of neutropenic patients with acute disseminated candidiasis, and nodular lesions caused by C. krusei in patients receiving fluconazole prophylaxis, occurring less frequently.

    Image-guided biopsy techniques are widely used in clinical practice. Commonly used methods employ either ultrasound (US) or computed tomography (CT) for image guidance. In certain patients, US or CT guidance may be suboptimal, or even impossible, because of artifacts, suboptimal lesion visualization, or both. We recently began performing magnetic resonance (MR)-guided biopsy of focal liver lesions in select pediatric patients with lesions that are not well visualized by US or CT. This report describes our experience performing MR-guided biopsy of focal liver lesions, with case examples to illustrate innovative techniques and novel aspects of these procedures. (orig.)

    The aim of this review is to describe the different imaging appearances of benign and malignant papillary breast lesions on mammography, ultrasound, and magnetic resonance imaging, according to the World Health Organization histopathological classifications. The classification and morphological imaging characteristics of papillary lesions remain challenging for pathologists and radiologists. Despite the difficulty of classifying these lesions, our review and those of others suggest that morphology is associated with clinically meaningful staging and outcome implications. Imaging can help to differentiate the forms of papillary lesion, but surgical specimens are required for definitive diagnosis in the majority of cases

    Imaging Efficiency was analyzed in 118 cases of benign lesion, including adenoma and 36 cases of malignant lesion without lymph node metastasis (Stage I) of 154 cases histologically diagnosed as elevated lesions of the gallbladder (443 lesions). On ultrasonography, the maximum diameter of the benign lesions, except in the case of adenomyomatosis, was 17 mm; the minimum diameter in the case of adenocarcinoma was 7 mm. The frequency of malignancy among elevated mucosal lesions of gallbladder with a diameter of 13 to 16 mm, except in the case of adenomyomatosis was 42.1% (8/19 lesions). Of the 91 out of total 154 cases in which the elevated lesions were 10 mm or smaller in a diameter, malignant cases were observed in 5.5% (5/91 cases). Many of the malignant lesions had a solid pattern of internal echo and there was a significant difference in depiction rate on plain CT between benign and malignant lesions. We conclude that plan CT examination is helpful to differentiate benign from malignant lesions of the gallbladder. (author)

    Morgellons disease is characterized by complaints of uncomfortable skin sensations and fibers emanating from nonhealing skin lesions. Morgellons disease is well-known in the dermatology and psychiatry literature, where it is typically considered a subtype of delusional parasitosis, but it has not yet been described in the ophthalmology literature. A patient with self-reported Morgellons disease is presented, who was referred for evaluation of left lower eyelid ectropion. She reported that her skin was infested with fibers that were "trying to get down into the eyelid." On examination, she had ectropion of the left lower eyelid, broken cilia, and an ulcerated left upper eyelid lesion concerning for carcinoma. Biopsy of the lesion was consistent with excoriation. Treatment of her ectropion was deferred out of concern for wound dehiscence, given the patient's aggressive excoriation behavior. This case is presented to make the ophthalmologist aware of this disorder and to highlight the appropriate clinical management.

    Full Text Available Growing evidence suggests a role for human papillomavirus (HPV in oral cancer; however its involvement is still controversial. This study evaluates the frequency of HPV DNA in a variety of oral lesions in patients from Argentina. A total of 77 oral tissue samples from 66 patients were selected (cases; the clinical-histopathological diagnoses corresponded to: 11 HPV- associated benign lesions, 8 non-HPV associated benign lesions, 33 premalignant lesions and 25 cancers. Sixty exfoliated cell samples from normal oral mucosa were used as controls. HPV detection and typing were performed by polymerase chain reaction (PCR using primers MY09, 11, combined with RFLP or alternatively PCR using primers GP5+, 6+ combined with dot blot hybridization. HPV was detected in 91.0% of HPV- associated benign lesions, 14.3% of non-HPV associated benign lesions, 51.5% of preneoplasias and 60.0% of cancers. No control sample tested HPV positive. In benign HPV- associated lesions, 30.0% of HPV positive samples harbored high-risk types, while in preneoplastic lesions the value rose to 59.9%. In cancer lesions, HPV detection in verrucous carcinoma was 88.9% and in squamous cell carcinoma 43.8%, with high-risk type rates of 75.5% and 85.6%, respectively. The high HPV frequency detected in preneoplastic and neoplastic lesions supports an HPV etiological role in at least a subset of oral cancers.Crecientes evidencias sugieren que el virus Papiloma humano (HPV tiene un rol en el cáncer oral; sin embargo su participación es todavía controvertida.

    Traumatic intracranial lesion has been one of the most frequent and serious problem in neurosurgical pathology. Computed tomography made it possible to get prompt diagnosis and surgical intervention of intracranial lesions by its safety, fastness and accuracy. Computed tomographic scan was carried out on 1309 cases at Soonchunhyang Chunan Hospital for 15 months from October 1983 to December 1984. We have reviewed the computed tomographic scans of 264 patients which showed traumatic intracranial lesion. The result were as follows: 1. Head trauma was the most frequent diagnosed disease using computed tomographic scans (57.8%) and among 264 cases the most frequent mode of injury was traffic accident (73.9%). 2. Skull fracture was accompanied in frequency of 69.7% and it was detected in CT in 38.6%: depression fracture was more easily detected in 81%. 3. Conutercoup lesion (9.5%) was usually accompanied with temporal and occipital fracture, and it appeared in lower incidence among pediatric group. 4. Intracranial lesions of all 264 cases were generalized cerebral swelling (24.6%), subdural hematoma (22.3%), epidural hematoma (20.8%), intracerebral hematoma (6.1%), and subarachnoid hemorrhage (3.0%). 5. The shape of hematoma was usually biconvex (92.7%) in acute epidural hematoma and cresentic (100%) in acute subdural hematoma, but the most chronic the case became, they showed planoconvex and bicconvex shapes. 6. Extra-axial hematoma was getting decreased in density as time gone by. 7. Hematoma density was not in direct proportion to serum hemoglobin level as single factor.

    Patchy parenchymal lesions of increased intensity were frequently identified in patients with cerebral hemorrhage in T2-weighted image of high-fields MR imaging. We studied 64 patients with brain hemorrhage to determine the frequency and distribution of those lesions. We defined an area with high intensity in T2 weighted and low or iso-intensity area in T1 weighted images smaller than 1.5 cm in diameter to be 'ischemic lesion'. Ishemic lesions were found in 48 (75%) of all cases; in 25 (75%) of 32 patients with putaminal hemorrhage, in 15 (100%) of 15 with thalamic hemorrhage, in 3 (33%) of 9 with subcortical hemorrhage. Multiple ischemic lesions were more frequently seen in thalamic hemorrhage than in putaminal hemorrhage. Only 5 (10%) of 48 cases with associated ischemic lesions had a previous history related to those lesions. Multivariable regression analysis identified hypertension as the major predictor of the presence of ischemic lesions. Patients with brain hemorrhage frequently accompanied with incidental ischemic lesions, making it difficult to establish a guideline of blood pressure control for prevention of recurrent stroke.

    Since several reports were published about CT differentiation of peridiaphragmatic fluid collection using 4 useful signs-diaphragm, displaced crus, bare area and interface signs. Transverse CT scans of 20 patients with abnormal diaphragmatic position due to large intrathoracic or intraabdominal lesion were analysed on the basis of those signs. Difficulties were encounted with differentiation when laterally located lesions did not extend to as far medially as crus, and when diaphragmatic stripe could not be distinguished from thickened pleura or adjacent wall of lesions. As a result, limited cases can be adequately assessed by diaphragm or displaced crus sign. Furthermore, bare area and interface signs seemed to be not useful at all. However relationship between caudal tip of lesions and thoracoabdominal wall was always constant in each thoracic or abdominal lesions. All of intrathoracic masses or empyemas were attached to thoracic wall displacing properitoneal and perirenal fat medially or inferiorly. By contraries, all of intraabdominal masses were separated from abdominal wall displacing properitoneal fat or peritoneum laterally. The key to accurate localization seemed to be identification of such relationship

    Isolated lesions of the medulla oblongata are difficult to diagnose due to their rarity and high biopsy risk. Several individual case reports have been published, but a systematic descriptive study is lacking. Our study has three objectives that 1) provide a differential diagnosis, 2) describe magnetic resonance imaging (MRI) findings, and 3) propose a stepwise MRI-based approach to the isolated lesions of the medulla oblongata in nonstroke patients. We performed an institutional Review Board-approved retrospective analysis of 34 consecutive cases of isolated medullary lesions from nonstroke causes identified from our imaging database between January 2000 and May 2015. Eleven were excluded due to lack of pretreatment or follow-up MRI. MR studies were reviewed by two blinded neuroradiologists. The diagnosis, demographic data, and MR findings were reported using frequencies and proportions. An MRI-based diagnostic algorithm was proposed. Most lesions were neoplasms (47%), followed by vascular malformations (15%), demyelinating/inflammatory lesions (15%), others (12%), unknown (8%), and infection (3%). Five MRI patterns were identified: 1) cystic lesion, 2) exophytic noncystic lesion, 3) intrinsic lesion with T2 hypointensity, 4) enhancing intrinsic lesion, and 5) nonenhancing intrinsic lesion. All showing patterns 1 and 2 were neoplasms or cysts. All showing pattern 3 were vascular malformations. Patterns 4 and 5 comprised of multiple etiologies. Neoplasms are the most common cause of isolated medullary lesions in nonstroke patients. Other differential diagnoses include vascular malformations, demyelinating/inflammatory lesions, and infections. A stepwise MRI-based approach can help differentiate between various etiologies.

    Full Text Available Ectopic adrenal tissue is usually found in kidney and retroperitoneum, yet other locations are considered uncommon. Spermatic cord remains one of the sites where this entity is mostly incidentally found during surgical procedure in childhood. Macroscopically, it represents as yellowish, lipomatous nodule. We present a case of ectopic adrenal tissue of spermatic cord in a 3- year- old boy, found during orchidopexy of the right testicle. Histopathological analysis of the spermatic cord nodule revealed adrenal cortical tissue composed of zona fasciculata cells. Although usually being benign and asymptomatic, cases of hyperplasia, adenoma and carcinoma arising from ectopic adrenal tissue have been reported. Therefore, removal of this tissue, when detected, is recommended.

    Thallium-201 ( 201 TI) brain SPECT, which can represent cellular activity of brain lesions, may provide more useful information in differentiating between benign and malignant brain lesions more so than CT or MRI, that merely represents anatomic changes or breakdown of blood brain barrier. We used 201 TI brain SPECT prospectively to evaluate the utility of 201 TI-indices as an indicator of benign or malignant lesions. We studied 28 patients. There were 13 cases of benign lesions (3: nonspecific benign lesion, 3: meningioma, 2: low grade glioma, 1: tuberculoma, central neurocytoma, hemangioblastoma, radiation necrosis, and choroid plexus papilloma) and 15 cases of malignant lesions (6: glioblastoma multiforme, 5: anaplastic glioma, 2: medulloblastoma, 1: metastasis and lymphoma). In all patients, CT and/or MRI were obtained and then 201 TI brain SPECT was obtained with measuring mean 201 TI index and peak 201 TI index. An unpaired t-test was performed to compare the 201 TI-indices and pathologic diagnoses to evaluate the utility of 201 TI-indices as an indicator of benign or malignant lesions. There were no statistically significant difference in 201 TI-indices between benign and malignant brain lesions (P>0.05). These results demonstrated that we could not use 201 TI indices on brain SPECT alone as an indicator of benign or malignant brain lesions

Results: Of the focal splenic lesions, 67% were correlated with an infective pathology with prevalence of Mycobacteria tuberculosis (75%), 26% were neoplastic and 6% splenic infarcts. The lesions were hypoechoic in 60% of the cases, while 10% were hypoanechoic and 1% anechoic. At CT, all lesions appeared hypodense, even after i.v. administration of contrast medium. Conclusion: The combination of echographic reports and clinical and laboratory data allows for a diagnosis that can be confirmed, and making a decision for effective therapy of AIDS is possible. CT does not provide any additional information

    The purpose of this study was to relate the pathological and imaging features of dural enhancement and meningeal sign ("dural tail") on contrast-enhanced T1-weighted magnetic resonance (MR) images from patients with primary calvarial lesions as well to assess the accuracy of MR imaging in predicting dural invasion. Thirty-two calvarial tumors studied with contrast-enhanced MR imaging and histopathological examination of the dural specimens were reviewed. Sixteen patients presented dural enhancement, eight with tumor invasion. Tumoral invasion of the dura was observed in one case without enhancement. Malignant lesions showed enhanced dura more commonly than benign lesions (P=0.02). Nodular and discontinuous dural enhancement was statistically associated with dural invasion (P=0.05). Dural tail did not show a specific pathological association. Meningeal enhancement is a nonspecific reaction to calvarial lesions unless nodular and discontinuous. False-negative and -positive cases of dural invasion imply some limitation of contrast-enhanced MR imaging in predicting dural invasion by calvarial neoplasms.

    We propose a new systematic approach in bifurcation lesions, modified jailed balloon technique (M-JBT), and report the first clinical experience. Side branch occlusion brings with a serious complication and occurs in more than 7.0% of cases during bifurcation stenting. A jailed balloon (JB) is introduced into the side branch (SB), while a stent is placed in the main branch (MB) as crossing SB. The size of the JB is half of the MB stent size. While the proximal end of JB attaching to MB stent, both stent and JB are simultaneously inflated with same pressure. JB is removed and then guidewires are recrossed. Kissing balloon dilatation (KBD) and/or T and protrusion (TAP) stenting are applied as needed. Between February 2015 and February 2016, 233 patients (254 bifurcation lesions including 54 left main trunk disease) underwent percutaneous coronary intervention (PCI) using this technique. Procedure success was achieved in all cases. KBD was performed for 183 lesions and TAP stenting was employed for 31 lesions. Occlusion of SV was not observed in any of the patients. Bench test confirmed less deformity of MB stent in M-JBT compared with conventional-JBT. This is the first report for clinical experiences by using modified jailed balloon technique. This novel M-JBT is safe and effective in the preservation of SB patency during bifurcation stenting. © 2017 Wiley Periodicals, Inc.

  20. Vascular lesions following radiation

    The special radiation sensitivity of the vascular system is mainly linked to that of endothelial cells, which are perhaps the most radiation-vulnerable elements of mesenchymal tissues. Within the vascular tree, radiation injures most often capillaries, sinusoids, and small arteries, in that order. Lesions of veins are observed less often, but in certain tissues the veins are regularly damaged (e.g., intestine) or are the most affected structures (i.e., liver). Large arteries do suffer the least; however, when significant damage does occur in an elastic artery (e.g., thrombosis or rupture), it tends to be clinically significant and even fatal. Although not always demonstrable in human tissues, radiation vasculopathy generally is dose and time dependent. Like other radiation-induced lesions, the morphology in the vessels is not specific, but it is characteristic enough to be often recognizable. Vascular injury, especially by therapeutic radiation is not just a morphologic marker. It is a mediator of tissue damage; perhaps the most consistent pathogenetic mechanism in delayed radiation injury
