    Objective: To determine the relative frequency and distribution of odontogenic and nonodontogenic cysts in a large Turkish population. Study Design A retrospective survey of jaw cysts was undertaken at the Oral Diagnosis and Radiology and Oral and Maxillofacial Surgery Department, Ondokuz Mayıs University Dental School, Samsun, Turkey. Data were retrieved from clinical files, imaging, and histopathology reports from 2000 to 2008; a total of 12,350 patients were included. In each case, we analyzed age, gender, type and number of cysts, and cyst location. Imaging patterns and pathologies associated with cystic lesions were also determined. Results: The prevalence of odontogenic and nonodontogenic cysts was 3.51%; males were affected more frequently than females. There were 452 odontogenic cysts (98.5%) and seven nonodontogenic cysts (1.5%). The most frequent odontogenic cyst was radicular (54.7%), followed by dentigerous (26.6%), residual (13.7%), odontogenic keratocyst (3.3%), and lateral periodontal cyst (0.2%). Nasopalatine duct cyst (1.5%) was the only nonodontogenic cyst. By age, cysts peaked in the third decade (24.2%). Concerning location, no statistically significant difference was found between the maxilla and mandible (p>0.05). The most frequent radiological feature of these lesions was unilocular cyst (93.7%). Pathologies associated with cystic lesions occurred in 14.7%. Conclusion: The prevalence of both odontogenic and nonodontogenic cysts were lower than that reported in many other studies. In our study population, cysts were mainly inflammatory in origin. Key words: Prevalence, odontogenic, nonodontogenic, cysts. PMID:21743428

    Full Text Available The objective of this article was to present two nonodontogenic conditions that may mimic odontogenic toothache: trigeminal neuralgia and burning mouth syndrome. Two cases are presented in which one is related to the upper left second premolar and the other is related to the upper left first molar. Both showed pain when chewing. These two cases highlight the complexities involved in diagnosing nonodontogenic toothache. This article demonstrates the importance of having a thorough knowledge of both odontogenic and nonodontogenic toothache, as well as the need for careful evaluation of the nature of the pain and history, clinical and radiographic examinations.

    The purpose of this study was to evaluate computed tomographic (CT) findings of deep neck space infection (DNSI) with particular attention to the differences in the spaces involved and in complications between odontogenic and nonodontogenic groups. Forty-four patients (21 odontogenic and 23 nonodontogenic) were included in this study. Among odontogenic DNSIs, 15 had the dental infection in the second or third mandibular molar. We compared the CT features between odontogenic and nonodontogenic DNSIs with special emphasis on the differences in the spaces involved and in the rate and type of complications. In all patients, CT clearly differentiated abscess from cellulitis. The most common spaces involved in 21 patients with odontogenic DNSI were the parapharyngeal (n = 18), the submandibular (n = 18), the anterior visceral (n = 13), the masticator (n = 9), and the sublingual (n 7) spaces. In contrast, in 23 patients with nonodontogenic DNSI, the anterior visceral space (n = 14) was most frequently involved. The parapharyngeal, the submandibular, and the masticator spaces were statistically more frequently involved in odontogenic than in nonodontogenic DNSI (ρ < .05). Twenty-two patients had one or more complications shown by CT, of which airway compromise was more frequent and severe in odontogenic than in nonodontogenic DNSI. We conclude that the parapharyngeal, the submandibular, and the masticator spaces are more significantly vulnerable in odontogenic DNSI than in nonodontogenic DNSI. The predilection for certain spaces of the neck in odontogenic DNSI seems to originate from the intimate relationship of the mandibular molars to the adjacent deep neck spaces

    Full Text Available Nasopalatine duct cyst (NPDC is the most common non-odontogenic cyst of oral cavity. Clinically, Nasopalatine duct cyst manifests as an asymptomatic swelling of the palate or the upper lip. Radiographically, it is seen as a heart-shaped radiolucency and can be confused with periapical pathology. The aim of this article is to report a case of a nasopalatine duct cyst in a 36-year-old patient which was misinterpreted for a periapical cyst. Diagnosis of a Nasopalatine duct cyst can be given through clinical, radiographical, and histopathological examination.

    Nasolabial cysts are rare, nonodontogenic, soft-tissue, developmental cysts occurring inferior to the nasal alar region. They are thought to arise from remnants of the nasolacrimal ducts and they are frequently asymptomatic. We report a rare case of bilateral nasolabial cysts accompanied by bilateral chronic dacryocystitis. A 48-year-old woman suffering from bilateral chronic dacryocystitis was referred to our department for endonasal dacryocystorhinostomy. She had undergone external dacryocystorhinostomy on the left side a few years earlier. Physical examination and computed tomography scan revealed nasolabial cysts bilaterally inferior to the nasal alar region. The cysts were removed via a sublabial approach and endoscopic dacryocystorhinostomy was performed on the right side. Ten months after surgery, the patient was asymptomatic. There may be a correlation, due to embryological reasons, between the presence of nasolabial cysts and the presence of chronic dacryocystitis. Both can be corrected surgically, under the same anaesthesia, without visible scar formation.

  9. Nasolabial Cyst Associated with Odontogenic Infection

    2016-01-01

    Full Text Available The nasolabial cyst or Klestadt cyst is a relatively uncommon nonodontogenic cyst that develops in the nasal alar region; it has uncertain pathogenesis. This lesion has slow growth and variable dimensions and is characterized clinically by a floating tumefaction in the nasolabial fold area around the bridge of the nose, causing an elevation of the upper lip and relative facial asymmetry. Diagnosis is primarily made clinically; if necessary, this is complemented by imaging. This paper reports the case of a 39-year-old male patient who complained of pain in the right upper premolar region and poor aesthetics due to a firm tumor in the right wing of the nose. Initially, this was thought to be due to an odontogenic abscess; however, the differential diagnosis was that a nasolabial cyst was communicating with the apex of teeth 14 and 15. Surgical treatment was carried out, followed by histopathological examination and concomitant endodontic treatment of the teeth involved.

    The nasolabial cyst is defined as nonodontogenic soft tissue lesion, rare and with occurrence in sagittal plane, between midline and nasal cartilage. Because its soft tissue composition, there is no radiographic presentation in conventional radiographic examination, being indicated evaluation through computed tomography and magnetic resonance imaging. In the present study, two cases are discussed, being one in white female subject, 72-year-old, and other in a black male subject, 24-year-old. The authors discuss about relevant aspects related to differential diagnosis through computed tomography and magnetic resonance imaging, as well as atypical features founded in one of the cases, like bilateral occurrence with different signal intensity in magnetic resonance imaging and determinant factors for differential diagnosis of soft tissues pathologies of maxillofacial complex, as fissure cysts with central occurrence (sagittal cysts), as dermoid cysts, palatine and nasopalatine and lateral fissure cysts.

    This study was for comparing healing patterns and effects between with odontogenic and nonodontogenic tissues on the defected mandible. Experimental bone defects that measured 3 mm in diameter were created on the mandibular body of guinea pig by removal of bone with the use of trephine burs and bone defects were grafted with Biogran (Orthovita Co., U.S. A.) and covered with Dura Mata (Pfrimmer-Viggo GmbH Co., Germany). Guinea pigs were serially terminated by fours on the 3 days, the 1 week, the 2 weeks, the 3 weeks, the 4 weeks, and the 5 weeks after experiment, and the mandibular body was removed and fixed with 10% neutral formalin. They were decalcified and embedded in paraffin as using the usual methods. The specimen sectioned and stained with hematoxylin and eosin and toluidine blue. They were observed with a light microscope and a polarizing microscope. The obtained results were as follows: 1. Defected bone was healed fast from the odontogenic tissues in early stage of the experiment. 2. The arrangement of the bone matrix was relatively regular in the bone from the nonodontogenic tissues, but irregular in the bone from the odotogenic tissues. 3. Compact bone has started to be absorbed and changed to the pattern of matrix bone tissue from 3 weeks after experiment.

  13. Role of cone beam computed tomography in the prompt diagnosis of a nasopalatine duct cyst

    Full Text Available The nasopalatine duct cyst (NPDC is the most common of all the developmental, epithelial, and non-odontogenic cysts of the maxilla, believed to originate from the epithelial remnants of the nasopalatine duct. Typically, the lesion is asymptomatic and is detected accidentally on a radiograph. The definite diagnosis must be based on the clinical, radiological, and histopathological findings. Frequently misdiagnosed, the NPDC is not rare. The motive of reporting an entity that is not very rare is that the lesion is mostly misdiagnosed, and to emphasize the importance of cone-beam computed tomography (CBCT in the diagnosis and optimized treatment planning of NPDCs.

  14. Bilateral endoscopic endonasal marsupialization of nasopalatine duct cyst

    Full Text Available Nasopalatine duct cysts are the most common non-odontogenic cysts in the maxilla, and are conventionally treated through a sublabial or palatine approach. Recently, the endoscopic approach has been used, but experience is extremely limited. We treated a 29-year-old male with nasopalatine duct cyst by endoscopic marsupialization, but paresthesia of the incisor region occurred after surgery. This paresthesia gradually remitted within 6 months. The nasopalatine nerve, which innervates the upper incisor region, enters two lateral canals separately at the nasal floor and exits the central main canal at the palate. Damage to the bilateral nasopalatine nerves might lead to paresthesia, so we recommend careful examination for nerve fibers during endoscopic surgery, especially if fenestration is performed on both sides.

    The objective of this study was to perform a cumulative analysis of odontogenic cysts obtained from the data of major dental institutions of Bangalore city, as well as to evaluate their distribution during a 5-year period and compare the results with other international studies. Data for the study were obtained from the reports of patients diagnosed with odontogenic cysts between 2005 and 2010 from different dental institutions of Bangalore. Case records of patients that fit the histological classification of the World Health Organization (WHO) (2005) were included in the study and the following variables were analyzed: age, gender, anatomic location, and histological type. In a total of 252 cyst specimens diagnosed, 79.76% were odontogenic cysts and 20.24% were nonodontogenic cysts. Among the odontogenic cysts most frequent lesions were radicular cysts (50.25%), followed by keratocysts (27.36%) and dentigerous cysts (22.39%). Our study provides a cumulative data of odontogenic cysts in the population of Bangalore city. The results of our study showed a similar frequency of odontogenic cysts as compared to other populations of the world, with radicular cyst being identified as the most frequent odontogenic cyst. Keratocyst was the second most common cyst followed by dentigerous cyst.

    Tumors of the pediatric facial skeleton represent a major challenge in clinical practice because they can lead to functional impairment, facial deformation, and long-term disfigurement. Their treatment often requires a multidisciplinary approach, and radiologists play a pivotal role in the diagnosis and management of these lesions. Although rare, pediatric tumors arising in the facial bones comprise a wide spectrum of benign and malignant lesions of osteogenic, fibrogenic, hematopoietic, neurogenic, or epithelial origin. The more common lesions include Langerhans cell histiocytosis and osteoma, while rare lesions include inflammatory myofibroblastic and desmoid tumors; juvenile ossifying fibroma; primary intraosseous lymphoma; Ewing sarcoma; and metastases to the facial bones from neuroblastoma, Ewing sarcoma, or retinoblastoma. This article provides a comprehensive approach for the evaluation of children with non-odontogenic tumors of the facial skeleton. Typical findings are discussed with emphasis on the added value of multimodality multiparametric imaging with computed tomography (CT), magnetic resonance imaging (MRI) with diffusion-weighted imaging (DWI), positron emission tomography CT (PET CT), and PET MRI. Key imaging findings and characteristic histologic features of benign and malignant lesions are reviewed and the respective role of each modality for pretherapeutic assessment and post-treatment follow-up. Pitfalls of image interpretation are addressed and how to avoid them. (orig.)

    To evaluate the usefulness of a dental CT software program in the assessment of jaw cysts and in the differentiation of odontogenic keratocysts and other cysts. Seventeen patients with proven jaw cysts(8 maxillae and 9 mandibles) were evaluated with a dental CT sofware program for location, locularity, the presence or absence of marginal scallping, and height to length ratio. For the delineation of involvement or displace-ment of neurovascular bundles, cortical erosion, perforation or expansion, and tooth root resorption by the jaw cysts, images from this program were compared to conventional images. Seventeen lesions icomprised 15 odontogenic cysts (five odontogenic keratocysts, five radicular, three residual and two dentigerous cysts) and two non-odontogenic cysts (one nasopalatine duct cyst and one postoperative maxillary cyst). Images of jaw cysts obtained with the dental CT software program delineated much more clearly than conventional images the status of neurovascular bundle and cortical bone, but there was no clear difference between the two modalities in delineating tooth root erosion. Dental CT findings of five mandibular odontogenic keratocysts were scalloped margin in all, mandibular ramus involvement in four, height to length ratio below 60% in four ,and multilocularity in two. The findings of the other 12 cysts (eight maxillae and four mandibles) were unilocularity in all, smooth inner margin in ten, height to length ratio below 60% in only two, and ramus involvement in none. A dental CT software program is an improved imaging modality for assessing jaw cysts;and findings which tend to indicate odontogenic keratocysts are marginal scalloping, mandibular ramus involvement, prominent spread along the marrow space and multilocularity

    The naso labial cyst is an uncommon non-odontogenic cyst that develops in the lower region of the nasal ala; its pathogenesis is uncertain. This lesion grows slowly and measures between 1.5 and 3 cm; it is characterized clinically by a floating tumefaction in the naso labial sulcus, which elevates the upper lip. The diagnosis is based on the clinical findings and, if necessary, image exams. This paper reports a case of a white 48-year-old Brazilian female patient that presented a firm tumor in the left ala of the nose; the clinical features suggested a naso labial cyst. CT scans revealed an expanding tumor with soft tissue density located in the left ala of the nose. It measured 1.2 cm in diameter and had a clear and well-defined outline; its homogeneous density was about 50 HU. MR images revealed a circular lesion located in soft tissue; T1 and T2 weighted signals were hyperintense, as were images after fat suppression. The diagnosis was a naso labial cyst, which was confirmed by histopathology after surgery. (author)

    Full Text Available Odontogenic cysts are the most common form of cystic lesions that affect the maxillofacial region. The low frequency of dentigerous cysts in children has been reported in dental literature. Dentigerous cysts arise as a result of cystic change in the remains of the enamel organ after the process of enamel formation is complete. They enclose the crown of an unerupted tooth and are attached to the cementoenamel junction. Although most dentigerous cysts are considered developmental cysts, some cases seem to have an inflammatory origin. The purpose of this report is to present a case of an 8-year-old male patient with a dentigerous cyst of inflammatory origin.

    Orthokeratinised odontogenic cyst (OOC) denotes the odontogenic cyst that microscopically has an orthokeratinised epithelial lining. OOC is characterised by a less-aggressive behaviour and a low rate of recurrence. This report describes a case of OOC involving posterior part of the mandible that mimicked periapical cyst in a 14-year-old boy. The initial clinical diagnosis was given as periapical cyst based on the clinical and radiographical features. Enucleation of the cyst was performed and the specimen was sent for histopathological examination. A definite diagnosis of OOC was made by histopathological examination of the biopsy specimen. This case emphases on including OOC in the differential diagnosis of radiolucencies occurring in the periapical region of non-vital tooth.

    BACKGROUND: The treatment of an ovarian cyst relies on its nature, and accurate preoperative discrimination of benign and malignant cysts is therefore of crucial importance. This study was undertaken to review the literature concerning the preoperative diagnosis and treatment of ovarian cysts....... METHODS: Articles concerning ovarian cysts from a medline literature search during the period 1985-2003 were included in addition to articles found as references in the initial publications. RESULTS: Different methods for discriminating between benign and malignant ovarian cysts are discussed....... The diagnosis and the treatment are assessed in relation to age, menopausal status, pregnancy, and whether the cyst is presumed to be benign or malignant. In general, expectant management is the choice in premenopausal and pregnant women with non-suspicious cysts and normal levels of CA-125. In postmenopausal...

    The therapeutic management of arachnoid cysts depends largely on its location. Almost 50% of arachnoid cysts are located in the temporal fossa-Sylvian fissure, whereas the other half is distributed in different locations, sometimes exceptional. Under the name of infrequent location arachnoid cysts, a description is presented of those composed of 2 sheets of arachnoid membrane, which are not located in the temporal fossa, and are primary or congenital.

    Hydatid cyst disease is common in our part of the world. Cardiac hydatid cyst is its rare manifestation. We report this case of 48-year male having isolated cardiac hydatid cyst, incidentally found on computed tomography. This patient presented in medical OPD of Combined Military Hospital, Lahore with one month history of mild retrosternal discomfort. His general physical and systemic examinations as well as ECG were unremarkable. Chest X-ray showed an enlarged cardiac shadow with mildly irregular left heart border. Contrast enhanced CT scan of the chest showed a large well defined multiloculated non-enhancing cystic lesion with multiple daughter cysts involving wall of left ventricle and overlying pericardium. Serology for echinococcus confirmed the diagnosis of hydatid cyst. Patient was offered the surgical treatment but he opted for medical treatment only. Albendezol was prescribed. His follow-up echocardiography after one month showed no significant decrease in size of the cyst. (author)

    Full Text Available Dermoid cysts are a developmental benign choristomas, which are congenital lesions representing normal tissue/s in an abnormal location. These consist of ectodermal and mesodermal elements, lined with epithelium and contain hair with other skin structures. Periorbital dermoid cyst is commonly located at lateral one third of the eyebrow. It is asymptomatic however school going child suffers from social stigma. So its surgical excision for cosmetic purpose becomes necessary. Excision also prevents bony remoulding and recurrent inflammatory responses due to leakage of cyst contents. In this article we are presenting a six years old male child having periorbital dermoid in lateral right eyebrow. The intact dermoid cyst was excised surgically and sent for histopathological examination, which confirmed the diagnosis of dermoid cyst. We highlight the merits of early surgical intervention, even in an asymptomatic periorbital dermoid cyst.

    Calcified hemorrhagic adrenal cysts are rather rare and unusual pathologic entity. Especially, the peripheral curvilinear calcification on roentgenogram is fairly characteristic picture of the cysts. Recently, we have experienced in Severance Hospital one of the classical cases of the benign calcified adrenal cyst in 35 year old white mail patient who has had vague abdominal pain and palpable mass in right abdomen. It has been reviewed several reports for adrenal cysts and hoped that this report may call additional attention of radiological diagnosis on this unusual disease.

    Full Text Available Congenital hepatic cyst is a rare and nonsymptomatic condition in infants and children. Its incidence is 2.5% in the postnatal life with a much lower incidence in the prenatal period. Incidental finding on antenatal imaging is the most common presentation. We present a case of a newborn in whom fetal ultrasound detected a cyst within the fetal liver. Postnatal imaging revealed a liver cyst in the right lobe of the liver, with no other intrahepatic structure affected. Liver function tests were abnormal, but the patient was asymptomatic. Posterior follow-up imaging showed a minor decrease in size. Management of congenital hepatic cyst is usually conservative, done with periodic ultrasound monitoring. However, surgical treatment is the mainstay of treatment when hydrops, progressive enlargement, hemorrhage, torsion, or compression of adjacent structures occurs. Malignant transformation can occur, but it is extremely rare. Partial or total removal of the cyst is the preferred treatment in neonates with a large lesion.

    Cysts of spleen are rare entities. Congenital splenic cysts are even more uncommon comprising of only 10% of benign non-parasitic cysts. We report a case of 22 years old female who presented with history of 2 years abdominal pain and gradual distension. Ultrasound and computed tomography (CT) both were suggestive of splenic cyst. Laboratory tests show thrombocytopenia with platelets count of 97000 per cubic millimeter and anemia with hemoglobin 8.7 gram per deciliter. Serological tests were negative for parasitic infection. Splenectomy was done and the weight of the spleen was found to be 1.5 kilogram. Histopathological findings are consistent with splenic epithelial cyst. The aetiology, diagnostic modalities and treatment options are discussed in the case report. (author)

    A 39-year-old woman was admitted to hospital with headaches, vomiting, psychic impairment and diplopia. Three hydatid cysts of the lung had been previously removed. An avascular mass in the left hemisphere with left-to-right displacement of the anterior cerebral arteries was noted during a brain angioscintigraphy. A cerebralthrombosis (CT) brain scan showed two cystic lesions situated in the left-frontal and occipital regions. A CT abdominal scan showed multiple cysts in the liver, spleen and both kidneys. At operation, two brain cysts were totally extirpated without rupture. The definite pathological diagnosis was secondry hydatid cysts. The headaches, vomiting and diplopia were persistent in the post-operative period. Seven days after the operation, a CT brain scan showed an infratenrorial cyst. The patient rejected any surgical intervention.

    The fallen fragment sign is a prominent radiologic feature in a minority of cases of unicameral bone cyst (20% in this series). This sign is always associated with pathologic fracture. Intramedullary fracture fragments may be single or multiple and may or may not be entirely dislodged from overlying periosteum. The finding appears limited to unicameral bone cysts in patients with open physes. When present, the fallen fragment is a pathognomonic finding as it defines the interior of the cyst as nonsolid.

    A 25-year-old male complained of intermittent, sharp pains about the left eye and in the left side of the chest. Neurological examination revealed paresthesia and impaired perception of touch and pin-pricks in the dermatomes of Th8 and Th9 on the left side. In all four extremities, the muscle stretch reflexes were equal and slightly hyperactive, without weakness or sensory deficits. Metrizamide myelography showed defective filling at the level between the upper 8th and 9th thoracic vertebrae. The lesion was also demonstrated by computed tomography (CT) scan performed 1 hour later, appearing as an oval, radiolucent mass in the left dorsal spinal canal, which compressed the spinal cord forward and toward the right. Serial sections of the spinal canal revealed the lesion to be partly filled with contrast medium. Repeat CT scan 24 hours after metrizamide myelography showed more contrast medium in the periphery of the lesion, giving it a doughnut-shaped appearance. At surgery a smooth-surfaced cyst containing sebum and white hair was totally removed from the intradural extramedullary space. The histological diagnosis was dermoid cyst. There have been a few reported cases of intracranial epidermoid cyst in which filling of the cyst was suggested on metrizamide CT myelography. These findings may complicate the differential diagnosis of arachnoid cyst and dermoid or epidermoid cyst when only CT is used. (author)

    Accurate segmentation of abdominal organs from medical images is an essential part of surgical planning and computer-aided disease diagnosis. Many existing algorithms are specialized for the segmentation of healthy organs. Cystic pancreas segmentation is especially challenging due to its low contrast boundaries, variability in shape, location and the stage of the pancreatic cancer. We present a semi-automatic segmentation algorithm for pancreata with cysts. In contrast to existing automatic segmentation approaches for healthy pancreas segmentation which are amenable to atlas/statistical shape approaches, a pancreas with cysts can have even higher variability with respect to the shape of the pancreas due to the size and shape of the cyst(s). Hence, fine results are better attained with semi-automatic steerable approaches. We use a novel combination of random walker and region growing approaches to delineate the boundaries of the pancreas and cysts with respective best Dice coefficients of 85.1% and 86.7%, and respective best volumetric overlap errors of 26.0% and 23.5%. Results show that the proposed algorithm for pancreas and pancreatic cyst segmentation is accurate and stable.

    Simple bone cysts (SBC) are pseudocysts occurring less commonly in the maxillofacial region. The uncertain and unclear etiopathogenesis led to numerous synonyms to refer this particular cyst. These cysts are devoid of an epithelial lining and are usually empty or contain blood or straw-colored fluid. In jaws initially it mimics a periapical cyst and later can lead to cortical bone expansion warranting for radical approach, which is seldom required. SBC is predominantly diagnosed in first two decades of life. Here we report a case of solitary bone cyst mimicking a periapical cyst of a mandibular molar in a 37-year-old patient.

    Epidermoid cysts are lesions, which form as a result of implantation of the epidermis in the layers of the dermis or the mucous membrane. The lesions are rare in adults with 7% occurring in the head and neck area and most often located in the submental region. In children population submental epidermoid cysts are extremely rare. The differential diagnosis of the lesions is necessary as it affects the choice of treatment methods. Among the pathological conditions occurring in that region, salivary retention cyst (ranula), thyroglossal duct cyst, vascular lymphatic malformation (cystic hygroma), median neck cyst, lymphadenopathy, thyroid gland tumor, laryngeal cyst, epidermoid and dermoid cysts, submental abscess, sialolithiasis and salivary gland inflammation should be considered. The authors of the present report demonstrate two cases of submental epidermoid cysts in children. Differential diagnosis in case of suspected submental epidermoid cyst in a child with proposed clinical practice and literature review is provided.

    Primary posterior mediastinal hydatid cyst is a serious health problem for the Mediterranean countries. We diagnosed a case of a 46-year-old female with a primary posterior mediastinum hydatid cyst on CT and MRI. It was provisionally identified as either a hydatid cyst or bronchogenic cyst or neuroenteric cyst. CT guided aspiration with 18 gauge needle confirmed as hydatid sand. This is very rare in this population but it should be kept in mind when one is looking at any cyst in the posterior mediastinum. (author)

    Accurate preoperative staging of ovarian chocolate cysts is very important because recent hormonal therapy has been effective in low stage patients. However, it has been difficult to assess the preoperative stage of ovarian chocolate cysts. We evaluated the diagnostic potential of MRI in preoperative staging of 15 overian chocolate cysts. It was well known that the older the ovarian chocolate cyst was the more iron content it had. We examined the iron contents effect on T1 and T2 relaxation times in surgically confirmed chocolate cysts (stage II: 3 cases, stage III: 3 cases and stage IV: 9 cases by AFS classification, 1985) employing the 0.15-T MR system and 200 MHz spectrometer. There was a positive linear relation between T1 of the lesion using the MR system (T1) and T1 of the resected contents using the spectrometer (sp-T1); r = 0.93. The same relation was revealed between T2 and sp-T2; r = 0.87. It was indicated that T1 and T2 using the MR system was accurate. There was a negative linear relation between T1 and the iron contents ( r = -0.81) but no relation between T2 and the iron contents. T1 was 412 ± 91 msec for stage II, 356 ± 126 msec for stage III and 208 ± 30 msec for stage IV. T1 for stage IV was shorter than that for stage II and III, statistically significant differences were noted (p < 0.05). Thus, T1 was useful in differentiating a fresh from an old ovarian chocolate cyst. We concluded that T1 relaxation time using the MR system was useful for the staging of an ovarian chocolate cyst without surgery. (author)

    2006-09-01

    Since their original description by Virchow, simple bone cysts have been studied repeatedly. Although these defects are not true neoplasms, simple bone cysts may create major structural defects of the humerus, femur, and os calcis. They are commonly discovered incidentally when x-rays are taken for other reasons or on presentation due to a pathologic fracture. Various treatment strategies have been employed, but the only reliable predictor of success of any treatment strategy is the age of the patient; those being older than 10 years of age heal their cysts at a higher rate than those under age 10. The goal of management is the formation of a bone that can withstand the stresses of use by the patient without evidence of continued bone destruction as determined by serial radiographic follow-up. The goal is not a normal-appearing x-ray, but a functionally stable bone.

  4. Bone cysts: unicameral and aneurysmal bone cyst.

    Science.gov (United States)

    Mascard, E; Gomez-Brouchet, A; Lambot, K

    2015-02-01

    Simple and aneurysmal bone cysts are benign lytic bone lesions, usually encountered in children and adolescents. Simple bone cyst is a cystic, fluid-filled lesion, which may be unicameral (UBC) or partially separated. UBC can involve all bones, but usually the long bone metaphysis and otherwise primarily the proximal humerus and proximal femur. The classic aneurysmal bone cyst (ABC) is an expansive and hemorrhagic tumor, usually showing characteristic translocation. About 30% of ABCs are secondary, without translocation; they occur in reaction to another, usually benign, bone lesion. ABCs are metaphyseal, excentric, bulging, fluid-filled and multicameral, and may develop in all bones of the skeleton. On MRI, the fluid level is evocative. It is mandatory to distinguish ABC from UBC, as prognosis and treatment are different. UBCs resolve spontaneously between adolescence and adulthood; the main concern is the risk of pathologic fracture. Treatment in non-threatening forms consists in intracystic injection of methylprednisolone. When there is a risk of fracture, especially of the femoral neck, surgery with curettage, filling with bone substitute or graft and osteosynthesis may be required. ABCs are potentially more aggressive, with a risk of bone destruction. Diagnosis must systematically be confirmed by biopsy, identifying soft-tissue parts, as telangiectatic sarcoma can mimic ABC. Intra-lesional sclerotherapy with alcohol is an effective treatment. In spinal ABC and in aggressive lesions with a risk of fracture, surgical treatment should be preferred, possibly after preoperative embolization. The risk of malignant transformation is very low, except in case of radiation therapy. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

    We report an extremely rare case of an epidermoid cyst in the kidney of a 74-year-old man who had presented with painless hematuria. Radiologic examination revealed a cyst in the kidney that was thought to be neoplastic. The patient underwent surgery to remove the cyst, and we received the nephrectomy specimen. A 6-cm cyst with no solid areas was seen. On histologic examination, this was an epidermoid cyst. We reviewed the published data and discuss the possible theories of origin of this rare condition.

    Full Text Available The calcifying odontogenic cyst (COC is reported to be associated with odontoma in 24% of cases. Separation of the cases of calcifying odontogenic cyst associated with odontoma (COCaO may lead to a better understanding of the pathogenesis of this lesion. The literature revealed 52 cases of COCaO. The male to female ratio was 1:1.9, with a mean age of 16 years. Most common location was the maxilla (61.5%. The radiographic appearance of most cases (80.5% was a well-defined, mixed radiolucent-radiopaque lesion. Histologically, the lesions consisted of a single large cyst with tooth-like structures as an integral part, giving the impression of a single lesion. In addition to the unique histologic features, differences in gender and distribution were found between the cases of COCaO and those of simple COC. COCaO may be regarded as a separate entity and classified as a benign, mixed odontogenic tumor. The term odontocalcifying odontogenic cyst is suggested.

    We studied 37 intradiploic epidermoid cysts, reviewing typical and atypical radiological features and the differential diagnosis. The most common clinical feature was a long standing lump in the scalp, occurring in 25 patients (67.7 %). Plain films were the most cost-effective radiological technique in diagnosis. The typical finding was a well-defined lytic lesion with sclerotic border, seen in 29 cases (78 %). Atypical lesions were those larger than 5 cm and/or with an ill-defined edge, being observed in 8 cases (22 %). CT and MRI were the best methods for assessing atypical ones. In all cases with typical radiological findings a preoperative diagnosis of intradiploic epidermoid cyst was suggested. (orig.). With 8 figs., 3 tabs

    2015-01-01

    There is still great controversy surrounding the origin of the arachnoid cyst. The most accepted theory in the case of congenital cysts explains how they are formed from an anomalous development of the arachnoid membrane, which is unfolded allowing the accumulation of cerebrospinal fluid inside and creating a cyst. This theory seems to explain the origin of convexity and sylvian cistern arachnoid cysts, whereas those in other locations might be due to other mechanisms. In the anatomopathological analysis, the arachnoid cyst wall can be seen as having few differences from normal, although thickened due to an increase quantity of collagenous material. A description of the embryological development of the arachnoid layer and cyst formation is presented, describing the main anatomopathological findings.

    Full Text Available Objective. The aim of this paper is to present an uncommon clinical and radiographic aspect of odontogenic keratocyst (OKC mimicking paradental cyst. Methods. A 32-year-old female patient showed a well-delimited radiolucent lesion connected with the root of the left third molar with close anatomical relationship with the mandibular canal. The clinical, radiographic, and anamnestic features lead us to diagnose a paradental cyst that was treated by enucleation after extraction of the partially impacted tooth. Results. Histological analysis showed typical histological features of PKC such as the presence of a lining of stratified squamous epithelium with a well-defined basal layer of palisading columnar of cuboidal cells. Conclusion. Initial X-ray analysis and the position of the lesion related to the third mandibular tooth caused us to mistakenly diagnose a paradental cyst. We were only able to identify the cyst as an PKC rather than a paradental cyst after histological analysis.

    Full Text Available A 52 year-old construction worker presented with progressive painful blurring of vision in the left eye associated with redness for past 1 month. There was a history of penetrating injury in the same eye 10 years ago and he underwent primary wound toilet and suturing, lens removal with intraocular lens implantation. Slit lamp examination revealed a corneal scar at 9’oclock, a large transilluminant iris cyst superotemporally and adherent to corneal endothelium. It was extended from angle of the pupil and obstructing the visual axis. The patient underwent excision of an iris cyst through superior limbal incision. Viscodissection was done to separate the cyst from the corneal endothelium and underlying iris stroma. Trypan blue ophthalmic solution was injected into the cyst to stain the cyst capsule. Post operatively 7 days, vision improved to 6/7.5 without complication. There was no recurrence up to 1 year postoperation. Histopathological finding revealed a benign cyst mass lined by simple cuboidal to nonkeratinized stratified squamous epithelium. We had achieved a good surgical outcome with no complication to date for our case study. We advocate this modified surgical method to completely remove iris cyst.

    To evaluate the incidence and characteristic findings of pineal cyst incidentally detected on magnetic resonance (MR) imaging. Brain MR images obtained in 2432 patients were retrospectively reviewed to determine the incidence and MR findings of pineal cysts, which were evaluated according to their size, shape, location, signal intensity, interval change, contrast enhancement and mass effect on adjacent structures. Cysts were encountered in 107(4.4 %) of 2432 patients evaluated. their size ranged from 1 X 1 X 1 to 15 X 8 X 9 (mean, 5.97 X 3.82 X 4.82)mm. All were spherical (n=53) or oval (n=54) in shape. Their margin was smooth and they were homogeneous in nature. On T1-weighted images, the cysts were seen to be hyperintense (n=57) or isointense (n=50) to cerebrospinal fluid, but less so than brain parenchyma. T2-weighted images showed them to be isointense (n=51)or hyperintense (n=56) to cerebrospinal fluid. The cysts were centrally located in 65 cases and eccentrically in 42. Compression of the superior colliculi of the tectum was demonstrated in 17 cases (15.9 %). NO patients presented clinical symptoms or signs related to either pineal or tectal lesions. Peripheral enhancement around the cyst after Gd-DTPA injection was demonstrated in 51 cases(100 %). Follow-up examinations in 19 cases demonstrated no interval change. The incidence of pineal cysts was 4.4 %. The MR characteristics of simple pineal cysts include: (1) an oval or spherical shape, (2) a smooth outer margin and homogeneous nature, (3) isosignal or slightly high signal intensity to cerebrospinal fluid on whole pulse sequences, (4) ring enhancement after contrast injection, (5) an absence of interval change, as seen during follow up MR study. These MR appearances of pineal cysts might be helpful for differentiating them from pineal tumors

    Objective: Ovarian cysts are the most frequently encountered intra-abdominal masses in females in utero. They may, at times, require perinatal intervention. Using magnetic resonance imaging (MRI) as an adjunct to ultrasonography (US) in prenatal diagnosis, we sought to demonstrate the ability to visualize ovarian cysts on prenatal MRI. Materials and methods: This retrospective study included 17 fetal MRI scans from 16 female fetuses (23–37 gestational weeks) with an MRI diagnosis of ovarian cysts after suspicious US findings. A multiplanar MRI protocol was applied to image and to characterize the cysts. The US and MRI findings were compared, and the prenatal findings were compared with postnatal imaging findings or histopathology. Results: Simple ovarian cysts were found in 10/16 cases and complex cysts in 7/16 cases, including one case with both. In 11/16 (69%) cases, US and MRI diagnoses were in agreement, and, in 5/16 (31%) cases, MRI specified or expanded the US diagnosis. In 6/16 cases, postnatal US showed that the cysts spontaneously resolved or decreased in size, and in 1/16 cases, postnatal imaging confirmed a hemorrhagic cyst. In 4/16 cases, the prenatal diagnoses were confirmed by surgery/histopathology, and for the rest, postnatal correlation was not available. Conclusion: Our results illustrate the MRI visualization of ovarian cysts in utero. In most cases, MRI will confirm the US diagnosis. In certain cases, MRI may provide further diagnostic information, additional to US, which is the standard technique for diagnosis, monitoring, and treatment planning.

    Epidermoid cysts are benign, uncommon lesions (1% of all intracranial tumors). Their localization is intradiploic in 25% of cases, and exceptionally subtentorial. We report here a rare case of giant intradiploic infratentorial epidermoid cyst. A 74-year old patient presented with recent diplopia and sindrome cerebellar. CT scan and MR imaging revealed a giant osteolytic extradural lesion of the posterior fossa (5.2 cm x 3.8 cm) with a small area of peripheral enhancement after contrast injection. Retrosigmoid suboccipital craniectomy allowed a satisfactory removal of the tumor, followed by an acrylic cranioplasty. The outcome was good. Neuropathological examination confirmed an epidermoid cyst. We review the literature and discuss our case.

    Full Text Available Epidermoid cysts are benign slow growing more often extra-axial tumors that insinuate between brain structures, we present the clinical, imaging, and pathological findings in 35 years old female patients with atypical epidermoid cysts which was situated anterior, middle & posterior cranial fossa. NCCT head revealed hypodense lesion over right temporal and perisylvian region with extension in prepontine cistern with mass effect & midline shift and MRI findings revealed a non-enhancing heterogeneous signal intensity cystic lesion in right frontal & temporal region extending into prepontine cistern with restricted diffusion. Patient was detoriated in night of same day of admission, emergency Fronto-temporal craniotomy with anterior peterousectomy and subtotal resection was done. The histological examination confirms the epidermoid cyst. The timing of ectodermal tissue sequestration during fetal development may account for the occurrence of atypical epidermoid cysts.

    2005-11-01

    SUMMARY Taxonomy: Superkingdom Eukaryota; kingdom Metazoa; phylum Nematoda; class Chromadorea; order Tylenchida; suborder Tylenchina; superfamily Tylenchoidea; family Heteroderidae; subfamily Heteroderinae; main genera Heterodera and Globodera. Cyst nematodes comprise approximately 100 known species in six genera. They are pathogens of temperate, subtropical and tropical plant species and the host range of many species is narrow. The most economically important species are within the Globodera and Heterodera genera. Globodera pallida and G. rostochiensis are important pathogens of potato crops. There are many economic species in the Heterodera genus, including Heterodera glycines (soybean cyst nematode), H. avenae (cereal cyst nematode) and H. schachtii (sugar beet cyst nematode), the last of which attacks a range of Chenopodiaceae and Cruciferae, including Arabidopsis thaliana. Disease symptoms: Field symptoms of severe cyst nematode infection are often stunting, wilting and chlorosis, but considerable yield loss can occur without obvious symptoms. The only unique indicator of cyst nematode infection is the presence of adult female nematodes attached to host roots after several weeks of parasitism. Disease control: This is usually achieved by using integrated pest management involving cultural practices such as crop rotation, resistant cultivars if available and chemical control when economically justified.

    Full Text Available Echinococcus granulosus is considered the major cause of humanhydatid cysts. Usually the duration of cyst formation is 10-20 years. This period shortens significantly upon rupture of aprimary cyst. The literature describes low incidence of primaryinvolvement of ovary as a site of hydatid cyst formation. Ourcase is the first report on ovarian hydatid cyst in Iran. A 60-year-old woman was presented with abdominal pain in the leftlower quadrant area. Paraclinical data were suggestive of neoplasiaand preoperative diagnosis was ovarian tumor. Duringlaparotomy, multiple cysts resembling hydatid cysts were observedin the left ovary. Pathological examination confirmed thediagnosis of hydatid cyst. Although there is a small possibilityof secondary ovarian echinococcal disease, it is more probablefor this case to be primary infection, as the patient had developedovarian hydatid cysts 15 years after hepatic involvementand recurrence after 30 months is very uncommon.

    In the present study expression of cyclin D1 in the epithelial lining of odontogenic keratocyst, radicular cyst, dentigerous cyst and glandular odontogenic cyst was investigated to compare proliferative activity in these lesions. Immunohistochemical staining of cyclin D1 on formalin-fixed, paraffin-embedded tissue sections of odontogenic keratocysts (n=23), dentigerous cysts (n=20), radicular cysts (n=20) and glandular odontogenic cysts (n=5) was performed by standard EnVision method. Then, slides were studied to evaluate the following parameters in epithelial lining of cysts: expression, expression pattern, staining intensity and localization of expression. The data analysis showed statistically significant difference in cyclin D1 expression in studied groups (p keratocysts, but difference was not statistically significant among groups respectively (p=0.204, 0.469). Considering expression localization, cyclin D1 positive cells in odontogenic keratocysts and dentigerous cysts were frequently confined in parabasal layer, different from radicular cysts and glandular odontogenic cysts. The difference was statistically significant (p keratocyst and the entire cystic epithelium of glandular odontogenic cysts comparing to dentigerous cysts and radicular cysts, implying the possible role of G1-S cell cycle phase disturbances in the aggressiveness of odontogenic keratocyst and glandular odontogenic cyst.

    To discuss the experience of diagnosis and treatment of ovarian cyst in infants. A retrospective review was conducted on 20 infants who suffered from ovarian cyst. There were no dysplasia ovarian was found in children which were preoperatively diagnosed simplex cyst. Within thirteen children preoperatively detected mixed cystic-solid lesion, six cases ovarian cysts disappeared and two cases underwent poor blood supply in the following time. Adverse effects for ovarian cyst in infants can be prevented by agressive surgical intervention. Harmful effects of ovarian cyst can be prevented by positive surgical intervention despite the diagnostic difficulties in children with clinical symptoms of this condition.

    Anamnesis and treatment of two cases of arachnoid cysts extending into the subarachnoid space are described. No traumatic incident was discovered in the previous history of these two patients. The causal genesis of neurological signs of deficiency in patients with arachnoid and acquired cysts is discussed. However, the cause of the development of a subdural hygroma in arachnoid cysts remains unclarified. CT findings of arachnoid cysts with a hypodense zone between brain surface and the vault of the cranium always require an investigation into the possibility of a spontaneous emptying of the cyst or of a congenital and not only localised extension of the cyst itself.

    Cystic mesothelioma is a rare benign tumor of the abdominal and pelvic peritoneum, consisting of solitary or multiple cysts. No more than 130 cases are reported. Several risk factors such as chronic peritoneal irritation, caused by foreign bodies, infection or endometriosis, were hypothesized but the pathogenesis is still unknown. A 51-year menopausal woman was submitted to ultrasonography because of abnormal uterine bleeding. The scan revealed a right ovarian cyst (size 81 x 64 mm) with the feature of serous cyst. In the anamnesis a cystectomy of the right ovary and appendectomy were reported. At laparoscopy, then converted in laparotomy, a cyst arising from peritoneum of the posterior surface of the uterus was found. The right ovary was normal. The histopathological finding was: serous simple cyst of peritoneum. Ultrasonographic diagnosis was not confirmed by surgery; in fact, sometimes, it may be difficult to establish the origin of pelvic cystic mass, from ovary or peritoneum, by ultrasonography. It is mandatory to suggest a laparoscopy and/or laparotomy in case of pelvic cystic mass that does not regress in the time even after administration of oral contraceptives.

    A perspective study was carried out to assess the efficacy of a combination of percutaneous aspiration plus oral albendazole to assess its efficacy as an alternative to surgery in the treatment of hydatid cyst. We performed percutaneous aspiration followed by injection of 20% hypertonic saline solution into 16 hydatid cysts in 13 patients. All the patients received oral albendazole (400 mg/12 hours) starting 2 days before and lasting until there weeks after the procedure. There were no anaphylactic reactions during or after the procedure. Follow-up included monthly ultrasound over a period ranging between 10 and 36 months. Three cysts disappeared completely; in 10 cases, the cysts cavity was replaced by a complex ultrasonographic findings, with strong signals similar to those of a pseudotumor. In another case, the aspirate was sterile and its morphology remained unchanged. In two cases, infection of the cyst ensued, requiring surgical treatment.

    Cystic duplications of the biliary tract are rare anomalies, easily mistaken for choledochal cysts. Surgical drainage is the preferred therapy for choledochal cyst, but cystic duplication necessitates surgical excision as duplications may contain heterotopic gastric mucosa leading to peptic ulceration of the biliary tract. We report a case of biliary tract duplication cyst containing heterotopic alimentary mucosa which had initially been diagnosed and surgically treated as a choledochal cyst.

    Hydatic cyst is an illness that appears in consequence of the cystic form of small strap-shaped worm Echinococcus granulosis. Frequently, cysts exist in the lungs and liver. Peritoneal involvement is rare, and generally occurs as a result of second inoculation from rupture of a liver-located hydatic cyst. Primary ovarian hydatic cyst is very rare. A 56-year-old female patient was admitted to Emergency Service with the complaint of stomachache and swollen abdomen. From ultrasonographic examina...

    A 56-year-old man presented himself for an intracranial glioblastoma multiforme excision. After being routinely monitored, he was preoxygenated. We induced anesthesia and paralysis with 200 mg propofol, 50 μg fentanyl and 9 mg vecuronium. Direct laryngoscopy with a Macintosh 3 blade revealed a 2x2 cm cyst, pedunculated, arising from the right side of the vallecula preventing the endotracheal intubation. While the patient remained anesthetized, we urgently consulted an otolaryngologist and aspirated the cyst with a 22-gauge needle and syringe under direct laryngoscopy. We aspirated 10 cc of liquid content. This was followed by an uneventful tracheal intubation with a 9.0 enforced spiral cuffed tube. An alternative to fiberoptic intubation may be careful cyst aspiration to facilitate the intubation.

    Intraparenchymal or intradiploic epidermoid cysts are very rare. Most of these cysts, when present, tend to involve the frontal and temporal lobes, and occasionally, the pineal gland or the brain stem. Here, we report a 45-year-old female, who presented with localized occipital headache and a tender occipital swelling, gradually increasing in size. She was hemodynamically and neurologically stable and did not have any focal neurological deficits. Whole skull and brain imaging revealed a well-demarcated expansile lytic lesion in the right occipital bone, which was hypointense on T1-weighted and hyperintense on both T2-weighted imaging and diffusion-weighted imaging without any contrast enhancement. The patient underwent a right occipital craniotomy and total excision of the intradiploic space occupying lesion. Histopathological examination confirmed the lytic bone lesion over occipital bone as intradiploic epidermoid cyst.

    Full Text Available Arachnoid cysts are rare, usually benign, space-occupying central nervous system lesion. They are the results of an accumulation of cerebrospinal-like fluid between the cerebral meninges and diagnosed prenatally as a unilocular, simple, echolucent area within the fetal head. They may be primary (congenital (maldevelopment of the meninges or secondary (acquired (result of infection trauma, or hemorrhage. The primary ones typically dont communicate with the subarachnoid space whereas acquired forms usually communicate. In recent years, with the development of radiological techniques, the clinical detectability of arachnoid cysts seems to have increased. We report a case of primary arachnoid cyst that were diagnosed prenatally by using ultrasonography and magnetic resonance imaging . [Cukurova Med J 2016; 41(4.000: 792-795

    Hydatid disease is a parasitic infestation with the larval stage of echinococcus which is found most frequently in Mediterranean area, Australia, and south America, and rarely in Korea. The case presented herein was a 43-year-old man who had been to the middle East Asia for three years. His initial ultrasonogram showed a well-defined cystic mass in the right hepatic lobe. It was surrounded by three layers of capsule and contained multiple small daughter cysts with echogenic debris. Computed tomograms and magnetic resonance images showed similar findings. Ultrasonography was the most accurate among the three imaging modalities in demonstrating the internal architecture of the echinococal cyst

    For 10 case in which we detected cysts in the choledochus ourselves comparing traditional radiological methods (infusion-cholegram, ERC, scintigraphy, barium meal examination, angiography) with recent imaging procedures (ultrasound, CT, NMR) the following sequence of procedures proved to be favorable: Screening methods are ultrasound and infusion-cholegram. CT and NMR furnish good presentations of the intra- and extrahepatic dilatations of the bile duct. ERC still represents the best methods for demonstration of an extrahepatic cyst of the choledochus. Hepato-biliary functional scintigraphy is performed as a supplement. Barium meal examination and coeliacography furnish a small diagnostic contribution only. (orig.) [de

    Arthroscopy is an advancing field in orthopedics, the applications of which have been expanding over time. Traditionally, excision of ganglion cysts has been done in an open fashion. However, more recently, studies show outcomes following arthroscopic excision to be as good as open excision. Cosmetically, the incisions are smaller and heal faster following arthroscopy. In addition, there is the suggested benefit that patients will regain function and return to work faster following arthroscopic excision. More prospective studies comparing open and arthroscopic excision of ganglion cysts need to be done in order to delineate if there is a true functional benefit. Copyright © 2014 Elsevier Inc.

    Branchial cleft anomalies are a common cause of lateral neck masses and may present with infection, cyst enlargement or fistulas. They may affect any of the nearby neck structures, causing compressive symptoms or vessel thrombosis. We present a case of a branchial cleft cyst in a 10-year-old boy who had been present for 1year. At the time of operation, the cyst was found to completely envelop the hypoglossal nerve. While reports of hypoglossal nerve palsies due to external compression from cysts are known, we believe this to be the first report of direct nerve involvement by a branchial cleft cyst.

    Hematic cyst refers to accumulation of blood or blood breakdown products in a non epithelium-lined fibrous tissue capsule. Hepatic cyst is a term often used for deeply placed, incompletely resorbed hematoma hemorrhagic cyst, which may remain unchanged and unidentified for long periods of time. Trauma is the major causative factor, although it is often vague or totally uncalled by the patient. Chronic hematic cysts are uncommon lesions those can present diagnostic challenge. In this article we report a first case of a chronic hematic cyst of the temporomandibular joint TMJ. (author)

  16. New insights about suprapatellar cyst

    Directory of Open Access Journals (Sweden)

    Tomislav Crnkovic

    2012-02-01

    Full Text Available bursa is located between the quadriceps tendon and femur, and it develops before the birth as a separate synovial compartment proximal to the knee joint. By the fifth month of fetal life there is a suprapatellar septum between the knee joint cavity and suprapatellar bursa which later perforates and involutes in a way that a normal communication between the cavity of bursa and knee is established. A small portion of the embrionic septum can later lag as more or less expressed suprapatellar plica. In case when suprapatellar plica has a small communication with valve mechanism or in case of complete septum, bursa becomes a separate compartment and potential location for the suprapatellar cyst development. Magnetic resonance imaging is recognised as the gold standard in diagnosis of knee cysts because of its ability to show cystic nature of the lesion, its relationship with other anatomic structures, as well as to establish whether other knee pathologies are present. Considering treatment possibilities, majority of cysts around the knee resolve spontaneously and should be treated by aspiration and application of corticosteroids. Suprapatellar cyst is a very rare knee pathology and it can in some occasions be treated using open or arthroscopic surgery.

    Is is shown that ultrasonography, computer tomography, laparoscopy provide for liver cyst detection. Parasitic cyst of Echinococcus and opisthhordeiasis nature are subject to surgical treatment. Selective procedures under echinococcosis include echinococcotomy and liver resection, and under opisthorchiasis - liver resection. Under nonparasitic liver cysts of minor size dynamic observation is advisable, under medium, hard and multiple complication cysts - sergical treatment is advisable. Selective procedures under non-complicated cysts include cyst resection with tamponage using omentum, and under complicated multiple cysts - liver resection

    Reinke edema is one of the common cause of dysphonia middle-aged population, and severe thickening of vocal folds require surgical treatment. Smoking plays a major role on etiology. Vocal fold cysts are also benign lesions and vocal trauma blamed for acquired cysts. We would like to present 3 cases with vocal fold cyst related with Reinke edema. First case had a subepidermal epidermoid cyst with Reinke edema, which could be easily observed before surgery during laryngostroboscopy. Second case had a mucous retention cyst into the edematous Reinke tissue, which was detected during surgical intervention, and third case had a epidermoid cyst that occurred 2 months after before microlaryngeal operation regarding Reinke edema reduction. These 3 cases revealed that surgical management of Reinke edema needs a careful dissection and close follow-up after surgery for presence of vocal fold cysts.

  19. Chrysophyte cysts as potential environmental indicators

    Science.gov (United States)

    Adam, David P.; Mahood, Albert D.

    1981-01-01

    Many Chrysophyte algae produce morphologically distinctive, siliceous, microscopic cysts during a resting stage of their life cycles; these cysts are often preserved in sediments. Scanning electron microscopy and Nomarski optics permit much more detailed observation of these cysts than was heretofore possible. We have used an ecologic and biogeographic approach to study the distribution of cyst forms in sediments and have established that many cyst types are found only in specific habitats, such as montane lakes, wet meadows, ephemeral ponds, and Sphagnum bogs. In the samples we have studied, cysts seem to be most common in fluctuating fresh-water habitats of low to moderate pH and some winter freezing. Numerous taxonomic problems have yet to be resolved. We believe that chrysophyte cysts have the potential to become a useful tool for both modern environmental assessments and paleoecological studies of Cenozoic fresh-water lacustrine deposits.

    The management of a unicameral bone cyst varies from percutaneous needle biopsy, aspiration, and local injection of steroid, autogenous bone marrow, or demineralized bone matrix to the more invasive surgical procedures of conventional curettage and grafting (with autogenous or allogenous bone) or subtotal resection with bone grafting. The best treatment for a unicameral bone cyst is yet to be identified. Better understanding of the pathology will change the concept of management. The aim of treatment is to prevent pathologic fracture, to promote cyst healing, and to avoid cyst recurrence and re-fracture. We retrospectively reviewed 17 cases of unicameral bone cysts (12 in the humerus, 3 in the femur, 2 in the fibula) managed by conservative observation, curettage and bone grafting with open reduction and internal fixation, or continuous decompression and drainage with a cannulated screw. We suggest percutaneous cannulated screw insertion to promote cyst healing and prevent pathologic fracture. We devised a protocol for the management of unicameral bone cysts.

    Sclerotherapy for renal cysts was performed, using 50% acetic acid as new sclerosing agent. We report the methods and results of this procedure. Fifteen patients underwent sclerotherapy for renal cyst, using 50% acetic acid. Because four patients were lost to follow-up, only 11 of the 15 were included in this study. The renal cysts, including one infected case, were diagnosed by ultrasonograpy (n=3D10) ormagnetic resonance imaging (n=3D1). The patient group consisted of four men and seven women(mean age, 59 years; range, 23-77). At first, the cyst was completely aspirated, and 25 volume% of aspirated volume was replaced with 50% sterile acetic acid through the drainage catheter. During the follwing 20 minutes, the patient changed position, and the acetic acid was then removed from the cyst. Finally, the drainage catheter was removed, after cleaning the cyst with saline. After treatment of infection by antibiotics and catheter drainage for 7 days, sclerotherapy in the infected case followed the same procedure. In order to observe changes in the size of renal cysts and recurrence, all patients were followed up by ultrasound between 2 and 8 months. We defined response to therapy as follows:complete regression as under 5 volume%, partial regression as 5-50 volume% and no response as more than 50 volume% of initial cyst volume. No clinically significant complication occured during the procedures or follow-up periods. All cysts regressed completely during follow-up of 8 months. Complete regression occurred as follows: two cysts at 2 months, seven cysts at 4 months, two cysts at 6 months. Two cysts showed residues at the last follow-up, at 4 and 6 months, respectively. The volume of residual cysts decreased to under 5 volume% of initial volume, however. Completely regressed cysts did not recurr during follow-up. Acetic acid sclerotherapy for renal cysts showed good results, regardless of the dilution of sclerosing agent with residual cyst fluid, and no significant

    An epidermoid cyst is a benign cyst usually found on the skin. Bone cysts are very rare and if they appear in bone they usually appear in the distal phalanges of the fingers. Epidermoid cysts of the jaws are uncommon. We present a case, of a 41 year-old female patient admitted to our department because of pain and swelling in the parotid and masseteric region-left side. There was no trismus, pathological findings in skin, high body temperature level, infra-alveolar nerves anesthesia or lymphadenopathy present. The orthopantomography revealed a cystic lesion and a unilocular lesion that included mandibular ramus on the left side with 3 cm in diameter. Under total anesthesia, a cyst had been reached and was enucleated. Histopathologic findings showed that the pathologic lesion was an epidermoid cyst. Epidermoid and dermoid cysts are rare, benign lesions found throughout the body. Only a few cases in literature describe an intraossesus epidermoid cyst. Our case is an epidermoid cyst with a rare location in the region of the mandibular ramus. It is not associated with any trauma in this region except medical history reveals there was an operative removal of a wisdom tooth 12 years ago in the same side. These cysts are interesting from the etiological point of view. They should be considered in the differential diagnosis of other radiolucent lesions of the jaws. Surgically they have a very good prognosis, and are non-aggressive lesions.

  3. Macrophage polarization differs between apical granulomas, radicular cysts, and dentigerous cysts.

    Apical periodontitis can appear clinically as apical granulomas or radicular cysts. There is evidence that immunologic factors are involved in the pathogenesis of both pathologies. In contrast to radicular cysts, the dentigerous cysts have a developmental origin. Macrophage polarization (M1 vs M2) is a main regulator of tissue homeostasis and differentiation. There are no studies comparing macrophage polarization in apical granulomas, radicular cysts, and dentigerous cysts. Forty-one apical granulomas, 23 radicular cysts, and 23 dentigerous cysts were analyzed in this study. A tissue microarray (TMA) of the 87 consecutive specimens was created, and CD68-, CD11c-, CD163-, and MRC1-positive macrophages were detected by immunohistochemical methods. TMAs were digitized, and the expression of macrophage markers was quantitatively assessed. Radicular cysts are characterized by M1 polarization of macrophages while apical granulomas show a significantly higher degree of M2 polarization. Dentigerous cysts have a significantly lower M1 polarization than both analyzed periapical lesions (apical granulomas and radicular cysts) and accordingly, a significantly higher M2 polarization than radicular cysts. Macrophage cell density in dentigerous cysts is significantly lower than in the periapical lesions. The development of apical periodontitis towards apical granulomas or radicular cysts might be directed by macrophage polarization. Radicular cyst formation is associated with an increased M1 polarization of infiltrating macrophages. In contrast to radicular cysts, dentigerous cysts are characterized by a low macrophage infiltration and a high degree of M2 polarization, possibly reflecting their developmental rather than inflammatory origin. As M1 polarization of macrophages is triggered by bacterial antigens, these results underline the need for sufficient bacterial clearance during endodontic treatment to prevent a possible M1 macrophage-derived stimulus for radicular cyst

    2015-01-01

    Full Text Available Introduction. Bronchogenic cysts are rare congenital anomalies of the embryonic foregut. They are caused by abnormal budding of diverticulum of the embryonic foregut between the 26th and 40th day of gestation. Bronchogenic cysts can appear in the mediastinum and pulmonary parenchyma, or at ectopic sites (neck, subcutaneous tissue or abdomen. So far, 70 cases of cervical localization of bronchogenic cysts have been reported. Majority of bronchogenic cysts have been diagnosed in the pediatric population. Bronchogenic cysts of the cervical area are generally asymptomatic and symptoms may occur if cysts become large or in case of infection of the cyst. The diagnosis is made based on clinical findings, radiological examination, but histopathologic findings are essential for establishing the final diagnosis. Treatment of cervical bronchogenic cyst involves surgical excision. Case Outline. Authors present a case of a 6-year-old female patient sent by a pediatrician to a maxillofacial surgeon due to asymptomatic lump on the left side of the neck. The patient had frequent respiratory infections and respiratory obstructions. Magnetic resonance imaging (MRI of the neck was performed and a well-circumscribed cystic formation on the left side of the neck was observed, with paratracheal location. The complete excision of the cyst was made transcervically. Histopathological findings pointed to bronchogenic cyst. Conclusion. Cervical bronchogenic cysts are rare congenital malformations. Considering the location, clinical findings and the radiological features, these cysts resemble other cervical lesions. Surgical treatment is important because it is both therapeutic and diagnostic. Reliable diagnosis of bronchogenic cysts is based on histopathological examination.

On conventional radiography, the lesion demonstrated a spherically trabeculated mass with a calcific rim. On CT scan, it showed a well-organized peripheral calcification resembling a myositis ossificans. On MRI, it presented as a multilocular, cystic lesion with fluid-fluid levels. The lesion had no solid components except for intralesional septa. Although findings on imaging and histology were identical to those described in classical aneurysmal bone cyst, diagnosis was delayed because of lack of knowledge of this entity and its resemblance to the more familiar post-traumatic heterotopic ossification (myositis ossificans).

    Full Text Available Lymphoepithelial cysts are benign, slowly growing unilocular or multilocular lesions that appear in the head and neck. They are also called Branchial cyst. The head and neck sites are the salivary glands(more commonly parotid and rarely submandibular gland and the oral cavity (usually the floor of the mouth. there are various methods of investigation available today, of which Fine needle aspiration cytology (FNAC can be used to provide an immediate diagnosis of a lymphoepithelial cyst. The other investigations include, Ultrasonogram,and Computed tomography.It usually occurs due to the process of lymphocyte-induced cystic ductular dilatation and the confirmatory diagnosis is always made postoperatively by histopathological examination. The mainstay in the treatment of a lymphoepithelial cyst remains the surgical approach, which includes complete enucleation of the cyst along with total excision of the involved salivary gland. This is a report of a lymphoepithelial cyst involving the submandibular salivary gland and its management.

    Full Text Available Orthokeratinized Odontogenic Cyst (OOC is a developmental cyst of odontogenic origin and was initially defined as the uncommon orthokeratinized variant of the Odontogenic Keratocyst (OKC, until the World Health Organization′s (WHO′s classification in 2005, where it was separated from the Keratocystic Odontogenic Tumor (KCOT. It is a relatively uncommon developmental cyst comprising of only 0.4% of all odontogenic cysts. It is rather mystifying that its radiographic features are similar to the dentigerous cyst and histological characteristics are similar to the odontogenic keratocyst; and it has inconsistent cytokeratin expression profiles overlapping with both the dentigerous cyst and odontogenic keratocyst as well as with the epidermis. It has a predilection for the posterior mandibular region. This is a report of a rare case of OOC in an unusual maxillary anterior region, with emphasis on its biological characteristics.

    CT is indispensable in the evaluation of renal masses, providing noninvasive and clear transverse images. With wider clinical application of CT, renal cysts have been found more frequently. CT examinations on 500 patients, who underwent CT for the diagnosis of renal diseases except for renal cysts, have been reviewed and analysed. The incidence of renal cysts was 9.6 % without prediction for sexes, but the incidence and sizes of the cysts increased with the advancing age. The upper portion of the kidneys was more frequently involved, but there was no relationship between number, sex and age of the patients. Since renal cysts produce mass effect in the kidneys, understanding of the nature and incidence of the renal cysts is important in diagnosing renal mass lesions. (author)

    Radicular cysts are inflammatory odontogenic cysts of tooth bearing areas of the jaws. Most of these lesions involve the apex of offending tooth and appear as well-defined radiolucencies. Owing to its clinical characteristics similar to other more commonly occurring lesions in the oral cavity, differential diagnosis should include dentigerous cyst, ameloblastoma, odontogenic keratocyst, periapical cementoma and Pindborg tumour. The present case report documents a massive radicular cyst crossing the midline of the palate. Based on clinical, radiographical and histopathological findings, the present case was diagnosed as an infected radicular cyst. The clinical characteristics of this cyst could be considered as an interesting and unusual due to its giant nature. The lesion was surgically enucleated along with the extraction of the associated tooth; preservation of all other teeth and vital structures, without any postoperative complications and satisfactory healing, was achieved.

    1981-01-01

    On the basis of the studies listed in the bibliography, this dissertation reports on the pathology, clinical symptoms and radiology of cysts of the semilunar cartilage. The author analyses 118 cases of his own, with special regard to the results of pneumo-arthrographic investigations carried through according to a special technique by Schaefer. In the course of this work, measurements of the meniscal base are for the first time used as radiological criteria indicating the presence of a cyst of the semilunar cartilage. Furthermore the well-known radiological signs of cysts, such as bone defects according to Albert and Keller, light central spot in the meniscal body, as well as Rauber's sign and horizontal rupture, are investigated as to the frequency of their incidence. For that purpose all the X-ray pictures were subjected to a further dose scrutiny. A list of all the 118 cases with their clinical and radiological data is found in the annex, together with the results of the operations and patho-anatomical investigations. (orig.) [de

    1999-03-01

    Unicameral bone cysts are not seen commonly in the calcaneus. Little is known about the etiology and natural history of these lesions. Calcaneal cysts often are symptomatic, although some of these lesions are detected as incidental findings. Treatment has been advocated based on the fear of pathologic fracture and collapse. Several published series have been divided in their favor for either open treatment or injection management. These series are small, and the optimal treatment is still in question. The current study compared the efficacy of methylprednisolone acetate injection treatment with curettage and bone grafting in the treatment of unicameral bone cysts of the calcaneus. All patients treated for unicameral bone cysts of the calcaneus during the past 7 years at two institutions were reviewed. Eleven patients met inclusion criteria. All diagnoses were confirmed radiographically or histologically. Demographic information, presenting complaints, diagnostic imaging, treatment modalities, and outcome were analyzed. Long term radiographic and subjective followup was obtained. Eighteen surgical procedures were performed on 11 patients with 12 cysts. Nine injections performed on six patients failed to show healing of the cyst. Nine cysts treated with curettage and bone grafting showed cyst healing. At mean followup of 28 months (range, 12-77 months), all 11 patients had no symptoms; there were no recurrences of the cyst in the nine patients who underwent bone grafting and persistence of the cyst in the two patients who underwent injection therapy. This review reports one of the largest series of cysts in this location. The results indicate that steroid injection treatment, although useful in other locations, may not be the best option for the management of unicameral bone cysts in the calcaneus. Curettage and bone grafting yielded uniformly good results.

    Among the pseudocysts of the jaws, the traumatic bone cyst is known as an asymptomatic lesion often noted unintentionally during routine radiographic examinations. The lesion neither devitalizes the teeth within its borders, nor does it cause resorption of their roots. The well-demarcated traumatic bone cyst often projects into the intraradicular septa and hence has been described as having scalloped borders. The following presentation is of a traumatic bone cyst that resembled periodontal pathology in its appearance.

    To describe characteristics of odontogenic cysts in a Mexican population. A retrospective study of 103 odontogenic cysts in 86 patients was done. The data were obtained from files of the Pathology Department of a General Hospital. We observed a frequency of the 8.13 % of odontogenic cysts (103) in 1266 pathological studies. The dentigerous cyst 56 % and odontogenic keratocyst 33 % were the most common odontogenic cysts. Sixty one percent of the cysts appeared in the second and third decades of life. In 71 cysts, 42 % appeared in the posterior region jaw, 29 % in the anterior region of the maxilla and 21 % in the posterior region of the maxilla. A 6.7 % developed a recurrence after treatment and a case of keratocyst of posterior region of the maxilla was associated with epidermoid carcinoma. The study included three women with the syndrome of carcinoma of the basal cell nevus, who presented multiple keratocysts. The dentigerous cysts and odontogenic keratocysts were the most frequent odontogenic cysts. They appeared mainly in the second and third decades of life.

    Background: The aim of the paper was the US evaluation of hormonal disorders and treatment results in adolescent girls and boys with breast cysts. Material/Methods: In the years 2001 - 2009, US examination of the breast was performed in 427 children aged 10 - 18 years, with clinically suspected breast pathologies. The indications for US examination typically included pain, breast swelling and a palpable tumor. The US examination was performed using a 7 - 12 MHz linear transducer. Results: Breast cysts were found in 42 children: 36 adolescent girls and 6 boys with gynaecomastia. Infected cysts were found in 35 children. The cysts ranged in size from 5 mm to 30 mm. In 5 of the girls, large cysts were treated by an incision and drainage, and in all the children with infected cysts, antibiotic therapy was used. Hormonal disorders were found in 30 girls. A follow-up examination was performed, and the observation time varied from 1/12 to 2 years. The cysts disappeared completely in 30 children. Hormonal therapy was introduced in 5 girls. Conclusions: Breast cysts found in US examinations are indications for check-up examinations including endocrinological diagnostics and, if the cyst is persistent, possibly for hormonal treatment.

    2014-01-01

    The so-called "globulomaxillary cyst", described as a fissural cyst, caused by entrapped epithelium between the nasal and maxillary process, is no longer considered for its own entity. Nevertheless, cystic lesions, which correspond to the previous image of globulomaxillary cysts, do still occur in daily practice. This raises the question to which entities pathological processes in this particular region actually belong to. In a retrospective study, 17 cases (12 men and 5 women, 12-59 years old) of primarily diagnosed globulomaxillary cysts are analysed according to clinical, radiological and histological aspects, catamnestic processed and assigned to a new entity. The results are compared with the international literature and draws conclusions on the diagnostic and therapeutic procedure. Seven lateral periodontal cysts, four radicular cysts, two keratocystic odontogenic tumours, one adenomatoid odontogenic tumour, one periapical granuloma, one residual cyst and one undefined jaw cyst were determined. According to the results of our study and the data from the international literature, the entity globulomaxillary cyst is no longer justified.

    Odontogenic cysts, which showed cystic radiolucency in the jaw bone by radiographic examination and computed tomography, were enucleated by operation in 3 dogs. One dog had a odontogenic keratocyst in the incisive bone of the right maxilla and another 2 cases revealed dentigerous cysts in the mandible. These cyst walls were enucleated or transpired by semiconductor laser. Afterwards, osteogenesis was confirmed at the defective part of jaw bone by extirpation of the cyst in all cases, and no recurrence has been noted in any cases. Odontogenic cyst is a disease which should be treated by surgical extirpation or transpiration.

    2009-05-01

    It is a general belief that large cyst-like periapical lesions and apical true cysts caused by root canal infection are less likely to heal after nonsurgical root canal therapy. Nevertheless, there is no direct evidence to support this assumption. A large cyst-like periapical lesion or an apical true cyst is formed within an area of apical periodontitis and cannot form by itself. Therefore, both large cyst-like periapical lesions and apical true cysts are of inflammatory and not of neoplastic origin. Apical periodontitis lesions, regardless of whether they are granulomas, abscesses, or cysts, fail to heal after nonsurgical root canal therapy for the same reason, intraradicular and/or extraradicular infection. If the microbial etiology of large cyst-like periapical lesions and inflammatory apical true cysts in the root canal is removed by nonsurgical root canal therapy, the lesions might regress by the mechanism of apoptosis in a manner similar to the resolution of inflammatory apical pocket cysts. To achieve satisfactory periapical wound healing, surgical removal of an apical true cyst must include elimination of root canal infection.

  2. Orbital dermoid and epidermoid cysts: Case study

    Directory of Open Access Journals (Sweden)

    Veselinović Dragan

    2010-01-01

    Full Text Available Introduction. Dermoid and epidermoid cysts of the orbit belong to choristomas, tumours that originate from the aberrant primordial tissue. Clinically, they manifest as cystic movable formations mostly localized in the upper temporal quadrant of the orbit. They are described as both superficial and deep formations with most frequently slow intermittent growth. Apart from aesthetic effects, during their growth, dermoid and epidermoid cysts can cause disturbances in the eye motility, and in rare cases, also an optical nerve compression syndrome. Case Outline. In this paper, we described a child with a congenital orbital dermoid cyst localized in the upper-nasal quadrant that was showing signs of a gradual enlargement and progression. The computerized tomography revealed a cyst of 1.5-2.0 cm in size. At the Maxillofacial Surgery Hospital in Niš, the dermoid cyst was extirpated in toto after orbitotomy performed by superciliary approach. Postoperative course was uneventful, without inflammation signs, and after two weeks excellent functional and aesthetic effects were achieved. Conclusion. Before the decision to treat the dermoid and epidermoid cysts operatively, a detailed diagnostic procedure was necessary to be done in order to locate the cyst precisely and determine its size and possible propagation into the surrounding periorbital structures. Apart from cosmetic indications, operative procedures are recommended in the case of cysts with constant progressions, which cause the pressure to the eye lobe, lead to motility disturbances and indirectly compress the optical nerve and branches of the cranial nerves III, IV and VI.

    Parathyroid cyst is an infrequent and unsuspected disease. There are more than 300 hundred cases reported in the world literature, a few of them are from Latin America. The experience of our centers and a review of the cases are presented. Case report of a series of patients with parathyroid cyst from our institutions according to the CARE guidelines (Case Reports). A search of Medline, Embase, BIREME ( Biblioteca Regional de Medicina ) LILACS ( Literatura Latinoamericana y del Caribe en Ciencias de la Salud ), Google Scholar and Scielo ( Scientific Electronic Library on Line ) databases and telephonic or email communications with other experts from Latin-America was performed . Six patients with parathyroid cyst were found in our centers in Colombia. Most of them were managed with aspiration of the cyst. Two of them required surgery. Only one case was functional. Twelve reports from Latin America were found for a total of 18 cases in our region adding ours. Parathyroid cysts are uncommonly reported in Latin America. Most of them are diagnosed postoperatively. Suspicion for parathyroid cyst should be raised when a crystal clear fluid is aspirated from a cyst. The confirmation of the diagnosis may be easily done if parathyroid hormone (PTH) level is measured in the cyst fluid.

    Aneurysmal bone cyst is a benign proliferative tumefaction of bone. Histologic similarities indicate a kinship among classic aneurysmal bone cysts, essentially 'solid' proliferative lesions in bones; giant cell reparative granulomas of the jaws, at the base of the skull, and in the small bones of the hands and feet; skeletal lesions of hyperparathyroidism; and even pseudosarcomatous myositis ossificans, proliferative myositis, and proliferative fasciitis.

    Omental and mesenteric cysts are uncommon diseases mostly occurring in young children. They are felt to have a common origin from obstructed or ectopic lymphatics. We reviewed three cases of omental cyst and three cases of mesenteric cyst. Sonography showed cystic mass with a thin wall and multiple thin septi dividing the cyst into multiple irregular spaces. In most cases(5/6) solid portions were detected and they were proved to be tissue debris and hemorrhagic clots. Fluid content was either anechoic or echogenic. Floating echogenicities or fluid-fluid level were detected in some cases. Ultrasound is very useful in the diagnosis of omental and mesenteric cysts in children, giving reliable information relating to internal hemorrhage, infection or adhesion to adjacent organs

    2011-01-01

    Spinal intramedullary epidermoid cyst is a rare condition. Recurrent epidermoid cyst in the spine cord is known to occur. The authors describe a case of recurrent conus medullaris epidermoid cyst in a 24-year-old female. She initially presented at 7 years of age with bladder disturbance in the form of diurnal enuresis and recurrent urinary tract infection. MRI lumbar spine revealed a 4 cm conus medullaris epidermoid cyst. Since the initial presentation, the cyst had recurred seven times in the same location and she underwent surgical intervention in the form of exploration and debulking. This benign condition, owing to its anatomical location, has posed a surgical and overall management challenge. This occurrence is better managed in a tertiary-care centre requiring multi-disciplinary treatment approach.

    Full Text Available Background. A six-year-old boy presented with a large progressive intracorneal and scleral cyst. Two years before, bilateral cataract surgery through a 6.5-mm corneal incision was performed elsewhere.Methods. The posterior wall of the cyst could be excised, as well as the anterior wall in the sclera. Upon histo-pathology the cyst wall was lined by epithelium. The epithelial cells of the anterior side in the cornea were removed with a curette and a corpus alienum drill. Three and a half years after removal of the cyst, there was no recurrence. Visual acuity was 0.8. Conclusions. An intracorneal and scleral inclusion cyst was successfully removed by surgical excision and the removal of epithelial cells by a curette and a corpus alienum drill.

    Oral foregut cysts are congenital choristomas that arise in the oral cavity during embryonic development from remnants of foregut-derived epithelium. This is an unusual report of a neonate with a large congenital sublingual cystic lesion, extending superficially from the left ventral tongue to the anterior floor of the mouth, impeding breast-feeding. The differential diagnosis included dermoid cyst, epidermoid cyst, mucous retention cyst, and oral lymphangioma. The treatment of choice was enucleation under general anesthesia. Histology showed a cystic lesion with a ciliated pseudostratified columnar epithelium with numerous goblet cells. Immunohistochemistry was positive for cytokeratin 7 and thyroid transcription factor 1 and negative for cytokeratin 20, resulting in a final diagnosis of an oral foregut cyst. Three weeks after surgery, the tongue had healed with good mobility, and breast-feeding could be established. No recurrence was present at 6 months of follow-up.

    Hydatid cysts in the neck are relatively exceptional, even in areas where Echinococcus granulosis is endemic, such as Asia. Although liver and lung are frequent sites of involvement, it can involve all tissues, with neck remaining one of the most rare sites. It should come in the differential diagnosis of cystic lesion of neck, as the treatment options differ widely from common neck cysts. The role of radiological investigation is important and, in these cases, the involvement of other organs should be investigated. Serological tests may be helpful. The major treatment modality is surgical and the cyst should be excised as a whole, without being ruptured, to prevent any treatment complications, as the cyst fluid can initiate an anaphylactic reaction. Postoperative albendazole therapy is recommended particularly when there is intra-operative spillover. We report a case of an isolated hydatid cyst localized in the anterior triangle of the neck without any pulmonary or hepatic involvement. (author)

    Full Text Available Pilonidal cysts and sinuses are described as dermoid cysts which contain follicles of hairs and sebaceous glands. They clinically present as a classic case of inflammation which comes with pain, local infection and redness. The origin of pilonidal disease remains controverse. There are many hypothesis as lack of hygiene on the affected area and a penetration and growth of a hair in the subcutaneus tissue caused by constant friction or direct trauma on the damaged area. The option for clinical treatment is very frequent. However, taking into consideration the incidence and the possibility of recidive, surgical treatment is presently recommended. Complications include cellulitis and abscess formation. Pilonidal cysts are mostly found on the sacral region. In the literature is found description of pilonidal cysts on the penis, interdigital region on the hands as well as on the cervical region. We present a case of pilonidal cyst located on the vault biparietal region, without malignant degeneration.

    The purpose of this study was to evaluate the CT findings of thyroglossal duct cysts. Sixteen patients with pathologically proved thyroglossal duct cysts were included in the study. CT scans were assessed retrospectively for shape, size, location, density of the central portions, septations, rim enhancement, changes in the adjacent fascial planes and investment within the strap muscles in the infrahyoid cysts. Thirteen cases of thyroglossal duct cysts were seen as round or oval cystic masses, two cases of them were seen as irregular-shaped lobulated cystic masses, and one case was seen as ovoid soft tissue mass. The cysts were from 1.4 to 5.7 cm in diameter (mean, 2.6 cm). The cyst was infrahyoid in 15 cases and suprahyoid in one case. The cyst was located in midline in eight cases, off midline in four cases, and both midline and off midline in four cases. The density of the central portions ranged from 15 to 82HU (mean, 32HU). Septations were noted in four cases. Rim enhancement was seen in 14 cases (93%), and heterogeneously enhancing soft tissue mass was seen in one case. In four cases, abnormal fascial planes were observed. All but one of the infrahyoid cysts (14/15) were embedded within the strap muscles, and one case of them was located anteriorly to strap muscles. CT permits one to make the diagnosis a thyroglossal duct cyst with a high degree of accuracy, as it can differentiate thyroglossal duct cysts from the other anterior neck masses by their typical location, characteristic morphology, and investment within the strap muscles

    OBJECT There is currently no consensus on the safety of sports participation for patients with an intracranial arachnoid cyst (AC). The authors' goal was to define the risk of sports participation for children with this imaging finding. METHODS A survey was prospectively administered to 185 patients with ACs during a 46-month period at a single institution. Cyst size and location, treatment, sports participation, and any injuries were recorded. Eighty patients completed at least 1 subsequent survey following their initial entry into the registry, and these patients were included in a prospective registry with a mean prospective follow-up interval of 15.9 ± 8.8 months. RESULTS A total 112 patients with ACs participated in 261 sports for a cumulative duration of 4410 months or 1470 seasons. Of these, 94 patients participated in 190 contact sports for a cumulative duration of 2818 months or 939 seasons. There were no serious or catastrophic neurological injuries. Two patients presented with symptomatic subdural hygromas following minor sports injuries. In the prospective cohort, there were no neurological injuries CONCLUSIONS Permanent or catastrophic neurological injuries are very unusual in AC patients who participate in athletic activities. In most cases, sports participation by these patients is safe.

    The pediatric dental approach to the oral cavity of newborns requires special attention, as many aspects are unique and peculiar to this period of life. It is important that pediatricians and pediatric dentists be aware of the characteristics within normal newborn patterns and prepared to make a correct diagnosis of abnormalities at early stages. Congenital eruption cysts (ECs) are rarely observed in newborns, as at this stage of a child's life, tooth eruption is unusual. This study reports a case of EC treated successfully by monitoring of the lesion, without any surgical procedure. In the 4th month, the lesion had completely regressed, and the deciduous central incisors had erupted without problems. The clinical and radiographic monitoring of ECs in newborns seems to be a satisfactory management procedure, similar to what is recommended for older children.

    Odontogenic cysts are the most common cysts of the jaws and are formed from the remnants of the odontogenic apparatus. Among these odontogenic cysts, radicular cysts (RCs) (about 60% of all diagnosed jaw cysts), dentigerous cysts (DCs) (16.6% of all jaw cysts) and odontogenic keratocysts (OKCs) (11.2% of all developmental odontogenic cysts) are the most common. The behavior of any lesion is generally reflected by its growth potential. Growth potential is determined by measuring the cell proliferative activity. The cell proliferative activity is measured by various methods among which immunohistochemistry (IHC) is the commonly used technique. Most of the IHC studies on cell proliferation have been based on antibodies such as Ki-67 and proliferating cell nuclear antigen. In the present study, the total sample size comprised of 45 cases of odontogenic cysts, with 15 cases each of OKC, RC and DC. Here, an attempt is made to study immunohistochemical (streptavidin-biotin detection system HRP-DAB) method to assess the expression of Ki-67 in different layers of the epithelial lining of OKCs, RCs and DCs. Ki-67 positive cells were highest in epithelium of OKC as compared to DC and RC. The increased Ki-67 labeling index and its expression in suprabasal cell layers of epithelial lining in OKC and its correlation with suprabasal cell layers of epithelial lining in DC and RC could contribute toward its clinically aggressive behavior. OKC is of more significance to the oral pathologist and oral surgeon because of its specific histopathological features, high recurrence rate and aggressive behavior.

    Squamous cell carcinoma arising in an odontogenic cyst is uncommon. The diagnosis of carcinoma arising in a cyst requires that there must be an area of microscopic transition from the benign epithelial cyst lining to the invasive squamous cell carcinoma. We report a histopathologically proven case of squamous cell carcinoma arising in a residual mandibular cyst in a 54-year-old woman.

    2003-06-01

    Full Text Available The management of a unicameral bone cyst varies from percutaneous needle biopsy, aspiration, and local injection of steroid, autogenous bone marrow, or demineralized bone matrix to the more invasive surgical procedures of conventional curettage and grafting (with autogenous or allogenous bone or subtotal resection with bone grafting. The best treatment for a unicameral bone cyst is yet to be identified. Better understanding of the pathology will change the concept of management. The aim of treatment is to prevent pathologic fracture, to promote cyst healing, and to avoid cyst recurrence and re-fracture. We retrospectively reviewed 17 cases of unicameral bone cysts (12 in the humerus, 3 in the femur, 2 in the fibula managed by conservative observation, curettage and bone grafting with open reduction and internal fixation, or continuous decompression and drainage with a cannulated screw. We suggest percutaneous cannulated screw insertion to promote cyst healing and prevent pathologic fracture. We devised a protocol for the management of unicameral bone cysts.

    To report the effectiveness of Minocin sclerotherapy in the treatment of renal cysts. We performed minocin sclerotherapy to 19 patients with 21 renal cysts composed of 17 cases of solitary renal cyst and three cases of multiple renal cyst and one case of polycystic kidney confirmed by ultrasound and CT. After aspiration of cyst fluid, if the amount was less than 50 ml, 500 mg of minocin was mixed with 3 ml of normal saline, if more than 50 ml, 1000 mg of minocin mixed with 5 ml of normal saline were injected, and each case was followed-up over 3 months by ultrasound. Of all 21 renal cysts, 14 cases were followed-up three months after minocin sclerotherapy. In 12 of 14 case, the size of the cysts decreased by 10% or collapsed completely. Of the remaining two cases, one collapsed after 6 months while the other recurred after 6 months. Three cases were followed up after 20 months and only one of them recurred. 19 of all 21 cases(91%) were cured, and two of 21 cases(9%) were recurred. Pain was the only complaint and four of 10 cases needed analgesics. Sclerotherapy with minocin has low recurrence-rate and low complication, and relatively early high cure-rate.

    2014-01-01

    Full Text Available Introduction. Hydatid disease (HD is an infestation that is caused by the larval stage of Echinococcus granulosus. The liver is affected in approximately two-thirds of patients, the lungs in 25%, and other organs in a small proportion. Primary retroperitoneal hydatid cyst is extremely rare. The most common complaint is abdominal pain; however, the clinical features of HD may be generally dependent on the location of the cyst. Case Presentation. A 43-year-old female was admitted with the complaint of abdominal pain. Her physical examination was normal. Computed tomography (CT revealed a 17 × 11 cm cystic lesion, with a thick and smooth wall that is located among the left liver lobe, diaphragm, spleen, tail of the pancreas, and transverse colon and invading the splenic hilum. Total cystectomy and splenectomy were performed. Pathological examination was reported as cyst hydatid. Discussion. Cysts in the peritoneal cavity are mainly the result of the spontaneous or traumatic rupture of concomitant hepatic cysts or surgical inoculation of a hepatic cyst. Serological tests contribute to diagnosis. In symptomatic and large hydatid peritoneal cysts, surgical resection is the only curative treatment. Total cystectomy is the gold standard. Albendazole or praziquantel is indicated for inoperable and disseminated cases. Percutaneous aspiration, injection, and reaspiration (PAIR technique is another nonsurgical option.

    2011-01-01

    Vocal cysts are benign laryngeal lesions, which affect children and adults. They can be classified as epidermic or mucous-retention cyst. The objective was to study the clinical, endoscopic, and surgical aspects of vocal cysts. We reviewed the medical charts of 72 patients with vocal cysts, considering age, gender, occupation, time of vocal symptoms, nasosinusal and gastroesophageal symptoms, vocal abuse, tabagism, alcoholism, associated lesions, treatment, and histological details. Of the 72 cases, 46 were adults (36 females and 10 male) and 26 were children (eight girls and 18 boys). As far as occupation is concerned, there was a higher incidence of students and teachers. All the patients had symptoms of chronic hoarseness. Nasosinusal (27.77%) and gastroesophageal (32%) symptoms were not relevant. Vocal abuse was reported by 45.83%, smoking by 18%, and alcoholism by 8.4% of the patients. Unilateral cysts were seen in 93% of the cases, 22 patients had associated lesions, such as bridge, sulcus vocalis, and microweb. Surgical treatment was performed in 46 cases. Histological analysis of the epidermic cysts revealed a cavity with caseous content, covered by stratified squamous epithelium, often keratinized. Mucous cysts presented mucous content, and the walls were coated by a cylindrical ciliated epithelium. Vocal cysts are benign vocal fold lesions that affect children and adults, being often associated with vocal overuse, which frequently affects people who use their voices professionally. Vocal symptoms are chronic in course, often times since childhood, and the treatment of choice is surgical removal. A careful examination of the vocal folds is necessary during surgery, because other laryngeal lesions may be associated with vocal cysts. Copyright © 2011 The Voice Foundation.

    2003-03-01

    To review management strategies for treatment of anterior chamber epithelial cysts. Retrospective review of consecutive interventional case series. Charts of patients treated for epithelial ingrowth over a 10-year period by a single surgeon were reviewed. Cases of anterior chamber epithelial cysts were identified and recorded, including details of ocular history, preoperative and postoperative acuity, intraocular pressure (IOP), and ocular examination, type of surgical intervention, and details of further procedures performed. Seven eyes with epithelial cysts were identified. Patient age ranged from 1.5 to 53 years at presentation. Four patients were children. In four eyes, cysts were secondary to trauma, one case was presumably congenital, one case developed after corneal perforation in an eye with Terrien's marginal degeneration, and one case developed after penetrating keratoplasty (PK). Three eyes were treated with vitrectomy, en bloc resection of the cyst and associated tissue, fluid-air exchange and cryotherapy. The last four eyes were treated with a new conservative strategy of cyst aspiration (three cases) or local excision (one keratin "pearl" cyst), and endolaser photocoagulation of the collapsed cyst wall/base. All epithelial tissue was successfully eradicated by clinical criteria; one case required repeat excision (follow-up, 9 to 78 months, mean 45). Two eyes required later surgery for elevated IOP, two for cataract extraction and one for repeat PK. Final visual acuity ranged from 20/20 to hand motions, depending on associated ocular damage. Best-corrected visual results were obtained in the more conservatively managed eyes. Anterior chamber epithelial cysts can be managed conservatively in selected cases with good results. This strategy may be particularly useful in children's eyes, where preservation of the lens, iris, and other structures may facilitate amblyopia management. Copyright 2003 by Elsevier Science Inc.

    2002-01-01

    Intraspinal synovial cysts of the lumbar spine are rare and commonly associated with osteoarthritis of the facet joints, particularly at level L4-L5. Symptoms are uncommon and may include low-back pain or sciatica. These cysts are accurately diagnosed by using computed tomography and magnetic resonance imaging. Diagnosis is essential for the correct management of the cysts. Several treatment options are available including rest and immobilization, computed tomography guided corticosteroid injection, and surgery in patients that are nonresponsive to other treatment methods.

    Although echinococcosis is not rare in South Africa, the location of a hydatid cyst in the thyroid is unusual. It usually presents as a solitary nodule, which may mimic a thyroid carcinoma. The routine use of aspiration cytology in the workup of cases of single thyroid nodules may complicate the further management of patients with a hydatid cyst of the thyroid; anaphylaxis and dissemination may occur and technical difficulties may be experienced during operation. A case of echinococcal cyst of the thyroid presenting as a single thyroid nodule, suspected to be thyroid cancer, is reported. 4 refs

  18. Parathyroid cysts: a clinical and radiological challenge.

    Witherspoon, Jolene; Lewis, Michael

    2012-02-01

    Parathyroid cysts are rare causes of neck swelling accounting for 0.6% of thyroid and parathyroid lesions. They may be functional, resulting in the release of parathyroid hormone, or non-functional. Non-functional cysts may be cosmetically unacceptable or cause dysphagia, dyspnoea or recurrent laryngeal nerve palsy as a result of compression. This article presents a young woman who was diagnosed with a thyroid cyst both on examination and imaging. However, the final histology confirmed this to be parathyroid in origin and this should be considered in the differential of such neck swellings.

    Full Text Available Intracranial dermoid cysts are congenital tumors of ectodermal origin. Rupture of these cysts can occur spontaneously, but rupture in association with trauma is reported infrequently. The diagnosis of rupture is made by the presence of lipid (cholesterol droplets in the subarachnoid spaces and ventricles. Nonenhanced CT of the head demonstrates multiple foci of low attenuation that correspond with hyperintense signal on T1-weighted MRI. We present a case of an adult patient with rupture of an intracranial dermoid cyst, precipitated by minor trauma.

    We report a case of a large posterior mediastinal neurenteric cyst in a neonate demonstrated by chest radiographs, barium swallow examination, ultrasonography and CT of the thorax. All the investigations revealed a large posterior mediastinal cystic mass with vertebral anomalies in the form of scoliosis and hemivertebra. The cyst was completely excised by a right posterolateral thoracotomy and biopsy showed the features of a neurenteric cyst. The rarity of the lesion prompted us to report this case Copyright (2005) Blackwell Publishing Asia Pty Ltd

    2012-01-01

    Full Text Available Arachnoid cysts are cerebrospinal fluid collections in the spine that can present with neurological symptoms or be discovered accidentally. Intradural location of such cysts especially in the lumbosacral region is relatively rare. The association of such cysts with other congenital anomalies such as tethered cord lends evidence to the developmental origin of arachnoid cysts. We report a case of lumbosacral arachnoid cyst with tethered cord in a 6-year-old male child and discuss the etiopathogenesis and management options.

    We recently encountered two large intrasellar arachnoid cysts extending to the suprasellar region. The intensity of the cyst contents was identical to that of the cerebrospinal fluid on both T1- and T2-weighted MRI. On contrast-enhanced MRI, the pituitary gland was compressed posteroinferiorly and flattened in the sella turcica. In this report of rare intrasellar arachnoid cysts the discussion is focused on dislocation of the pituitary gland. (orig.)

    2008-01-01

    Objective: To present the prevalence and imaging findings of patients with hydatid disease (HD) showing features of migration or herniation of the hydatid cysts (HCs) and underline the clinical significance of this condition. Materials and methods: Between May 2003 and June 2006, 212 patients with HD were diagnosed by abdomen and/or thorax CT, searched for migrating or herniating HC. Imaging findings of 7 patients (5 women, 2 men with an age range of 19-63 years; mean ± S.D., 44 ± 19 years) with HD showing transdiaphragmatic migration (6 subjects) or femoral herniation (1 subject) were evaluated. Diagnosis of all the patients were established by pathologic examination and migration or herniation was confirmed by surgery in all patients. Results: Liver HD were identified in 169 (79.7%) of 212 patients with HD. Transdiaphragmatic migration of HCs were identified in 6 (3.5%) of the 169 patients with liver HD. In one patient, femoral herniation of the retroperitoneal HC into the proximal anterior thigh was identified. All of these seven patients exhibiting migration or herniation of HCs had active HCs including 'daughter cysts'. Two patients had previous surgery because of liver HD and any supradiaphragmatic lesion was not noted before operation. Findings of migration or herniation were confirmed by surgery. Conclusion: Active HCs may show migration or herniation due to pressure difference between the anatomic cavities, and in some of the patients, by contribution of gravity. Previous surgery may be a complementary factor for migration as seen in two of our patients. The possibility of migration or herniation in patients with HD should be considered before surgery

    2012-01-01

    Full Text Available Botryoid odontogenic cyst (BOC is considered to be a polycystic variant of the lateral periodontal cyst (LPC as the specimen resembled a cluster of grapes. It is a non-inflammatory odontogenic cyst. The BOCs can be unicystic or multicystic. These cysts have potential to extend in the bone and become multilocular and they have a high recurrence rate. Till now, only 73 cases of BOC have been reported. The pathogenesis of BOC is still debatable. We review different pathogenesis proposed for BOC and discuss a rare case of BOC developing from lining of an abnormally large LPC which showed aggressive behaviour in terms of growth and size.

    We describe two patients with cyst-like lesions of bone that developed at sites of healed or healing fractures. One case showed histological features of a unicameral bone cyst, which, to the best of our knowledge, is a previously unreported finding in a post-traumatic cyst. It is suggested that there are two principal clinical and radiological types of post-traumatic cyst, of which each of our cases represents an example: (1) asymtompatic transient cortical lesions, found only in children, and (2) more central expanding lesions, found in a wider age group and associated with pain, swelling, and pathological fractures.

    1999-01-01

    Purpose: To describe the findings of sacral meningeal cysts (SMCs) on MR myelography and assess its value for the diagnosis of SMCs. Material and Methods: We evaluated the MR images and MR myelograms obtained from 10 patients with SMC. MR myelograms were obtained using a 2D or 3D single-shot fast spin-echo sequence. In 5 patients, X-ray myelograms and postmyelographic CT images were compared with the MR myelograms. Results: A total of 33 SMCs were diagnosed within the spinal canal and/or sacral foramen. MR myelograms clearly revealed each cyst as a well-defined mass showing hyperintensity (10 cysts) or isointensity (23 cysts) compared to cerebrospinal fluid. MR myelograms demonstrated SMCs better than X-ray myelograms and postmyelographic CT images in 3 of the 5 patients. Conclusion: MR myelography can be an adjunct to conventional imaging techniques when surgical treatment is indicated, because it can precisely delineate the extent of SMCs. (orig.)

  10. Medical image of the week: bronchogenic cysts

    Directory of Open Access Journals (Sweden)

    2018-03-01

    Full Text Available Bronchogenic cysts are congenital foregut malformations forming from abnormal budding of the bronchial tree between the 4th and 6th weeks of embryonic development. While identified primarily in children, the cysts are often asymptomatic and may not be identified until adulthood. Most (70% are within the middle mediastinum and contain fluid or proteinaceous material. When involving the parenchyma, they generally do not communicate with the tracheobronchial tree. Communication with the airways may develop following infection, procedures, or trauma and may result in lesions with an air-fluid level (Figures 1 and 2. Bronchogenic cysts may be complicated by infection, bleeding, fistula formation, or most concerning, by malignant transformation. Unless the cyst contains air, it may manifest as a solitary pulmonary nodule on plain radiographs. Computed tomography or T2-weighted MRI images are used to confirm the diagnosis.

    The Dermoid cyst account for the 0.01 % of all cysts of buccal cavity. Its more frequent location is in the mouth floor. This is the case of a female patient aged 19 who approximately 7 years noted an increase of volume under tongue growing gradually and noting outside face and the discomfort at to speak and to chew. Complementary studies were conducted and under general anesthesia a surgical exeresis was carried out by intrabuccal approach achieving excellent esthetic and functional results. Histopathologic diagnosis matched with a dermoid cyst of mouth floor. Patient has not lesion recurrence after three years after operation. We conclude that the Dermoid cyst of mouth floor appear as benign tumor of middle line. The intrabuccal exeresis demonstrates esthetic and functional benefits. (author)

    An air-filled paratracheal cyst is a common radiological finding. It may be a congenital defect or an acquired lesion. 'Acquired paratracheal cyst' is the term given to the acquired abnormalities, which usually arise in adults. They result from a weakness of the tracheal wall, and they may be caused by trauma, infection, high pressure injuries, long lasting tracheostomy, and obstructive tracheal disease. Majority of the paratracheal air cysts are asymptomatic and are discovered incidentally on radiological images. Also, the management is primarily conservative treatment. Here, we report a case of an infected paratracheal air cyst on the right posterolateral wall of the trachea, which developed into an abscess and was visualized on follow-up multidetector computed tomography and was surgically removed due to persistent symptoms

    Hydatic disease caused by Echinococcus granulosus is an endemic disease and an important public health problem in some countries of the world. The results of surgical treatment are associated with a high rate of mortality, morbidity, postoperative recurrence and a long period of hospital stay and the medical treatment results are still controversial. Although the percutaneous aspiration and treatment of liver hydatid cysts were considered to be contraindicated due to risks of anaphylactic shock and dissemination of clear-crystal fluid into the abdomen, several reports of successful percutaneous treatment of liver hydatid cysts have been published in the literature. Today, percutaneous treatment of liver hydatid cysts is the most effective and reliable treatment procedure in the selected cases. In this review, indications, contraindications, method and techniques, healing criteria, complications, results and importance of the percutaneous treatment of liver hydatid cysts are discussed.

    Full Text Available Cardiac hydatidosis is rare presentation of body hydatidosis. Incidence of cardiac involvements range from 5% to 5% of patients with hydatid disease. Most common site of hydatid cyst in heart is interventricular septum and left ventricular free wall. Right ventricular free wall involvement by cyst that ruptured to pericardial cavity is very rare presentation of hydatid cyst. Cardiac involvement may have serious consequences such as rupture to blood steam or pericardial cavity. Both the disease and its surgical treatment carry a high complication rate, including rupture leading to cardiac tamponade, anaphylaxis and also death. In the present report, a 43-year-old man with constrictive pericarditis secondary to a pericardial hydatid cyst is described.

    Full Text Available Ventriculoperitoneal (VP shunt is one of the commonest procedures done in neurosurgical practice throughout the world. One of the commonest problems after putting the VP shunt is the shunt obstruction, which can be due to varied causes. Shunt obstruction secondary to the parasitic infections is rarely seen. We are presenting a 15-year-old child, a case of operated cerebral hydatid cyst with hydrocephalus. She presented with shunt malfunction after 1 year of surgical excision of the hydatid cyst. Revision of the VP shunt was done and peroperatively, it was found that the shunt tubing was obstructed due to small hydatid cysts. This is the first reported case of VP shunt obstruction by hydatid cyst.

    Full Text Available A 21-year-old male with developmental delay presented with abdominal pain of two days' duration. He was afebrile and his abdomen was soft with mild diffuse tenderness. There were no peritoneal signs. Plain x-ray demonstrated a large air-filled structure in the right upper quadrant. Computed tomography of the abdomen revealed a 9×8 cm structure adjacent to the hepatic flexure containing an air-fluid level. It did not contain oral contrast and had no apparent communication with the colon. At operation, the cystic lesion was identified as a duplication cyst of the sigmoid colon that was adherent to the right upper quadrant. The cyst was excised with a segment of the sigmoid colon and a stapled colo-colostomy was performed. Recovery was uneventful. Final pathology was consistent with a duplication cyst of the sigmoid colon. The cyst was attached to the colon but did not communicate with the lumen.

    Full Text Available Epidermal inclusion cysts are uncommon in the breast, but the consequences can besevere when these cysts occur in the breast parenchyma. Here,we report two suchcases. The patient in case 1 was an 37-year-old woman with a 3-cm palpable mass inthe right breast. Mammography revealed a round and smoothly outlined mass, whichindicated a benign tumor, and sonography showed an irregularly shaped and heterogeneoushypoechoic mass, fibroadenoma was suspected on the basis of clinical andimage findings, but excisional biopsy revealed an epidermal inclusion cyst. The patientin case 2 was a 50-year-old woman with a 2.5-cm lesion in the left breast. Mammographyrevealed a round, dense, smoothly outlined mass, and sonography showeda well-defined, central hyperechoic mass. . Breast cancer was suspected on the basisof the sonographic findings and the age of the patient, but the resected specimen revealedan epidermal inclusion cyst. Although epidermal inclusion cysts are benign,occasionally they may play a role in the origin of squamous carcinoma of the breast. .Mammographic and sonographic features of an epidermal cyst may mimic a malignantlesion. Malignant change appears to occur more frequently in epidermal inclusioncysts in the mammary gland, compared to common epidermal inclusion cysts,and this may be associated with origination of mammary epidermal inclusion cystsfrom squamous metaplasia of the mammary duct epithelium.Epidermmoid inclusion cyst of the breast is potentially serious, although such cystsare rare, and differentiation from a malignant or benign breast tumor is required. Excisionis probably the most appropriate treatment, and can eliminate the possible riskof malignant transformation.

    The soybean cyst nematode (SCN), Heterodera glycines, causes economically significant damage to soybeans (Glycine max) in many parts of the world. The cysts of this nematode can remain quiescent in soils for many years as a reservoir of infection for future crops. To investigate bacterial communities associated with SCN cysts, cysts were obtained from eight SCN-infested farms in southern Ontario, Canada, and analyzed by culture-dependent and -independent means. Confocal laser scanning microscopy observations of cyst contents revealed a microbial flora located on the cyst exterior, within a polymer plug region and within the cyst. Microscopic counts using 5-(4,6-dichlorotriazine-2-yl)aminofluorescein staining and in situ hybridization (EUB 338) indicated that the cysts contained (2.6 +/- 0.5) x 10(5) bacteria (mean +/- standard deviation) with various cellular morphologies. Filamentous fungi were also observed. Live-dead staining indicated that the majority of cyst bacteria were viable. The probe Nile red also bound to the interior polymer, indicating that it is lipid rich in nature. Bacterial community profiles determined by denaturing gradient gel electrophoresis analysis were simple in composition. Bands shared by all eight samples included the actinobacterium genera Actinomadura and STREPTOMYCES: A collection of 290 bacteria were obtained by plating macerated surface-sterilized cysts onto nutrient broth yeast extract agar or on actinomycete medium. These were clustered into groups of siblings by repetitive extragenic palindromic PCR fingerprinting, and representative isolates were tentatively identified on the basis of 16S rRNA gene sequence. Thirty phylotypes were detected, with the collection dominated by Lysobacter and Variovorax spp. This study has revealed the cysts of this important plant pathogen to be rich in a variety of bacteria, some of which could presumably play a role in the ecology of SCN or have potential as biocontrol agents.

    This paper reports on the diagnosis of mediastinal foregut cysts which are difficult to establish even with CT, because these lesions often have high attenuation numbers similar to tumors. This study was undertaken to determine the value of MR imaging in the diagnosis of foregut cysts. MR imaging of 58 mediastinal masses was performed between 1986 and 1991 at 0.5 T, with T1- and T2-weighted images obtained. Seven foregut cysts were identified. Five were pathologically proven; in two cases the diagnosis was based on clinical findings and radiologic stability. Signal characteristics were compared with those of 52 pathologically proven mediastinal masses: six thymomas, 10 thyroid goiters and carcinomas, 11 neurogenic tumors, 15 lymphomas, and 10 miscellaneous masses. Fat and muscle were used as internal standards of signal intensity (SI). All foregut cysts were very bright on T2-weighted images. On T1-weighted sequences, two had low SI, but the remaining five showed high SI. These differences reflected variability in cyst protein content, high SI indicating the presence of mucus. On T1-weighted images, low SI was identified in most other mediastinal masses, but uniform high SI was specific for foregut cysts. Our series did not include any fatty lesions, as these were easily recognized on CT scans

  10. Primary hydatid cyst in gastrocnemius muscle

    Full Text Available Cystic echinococcosis, which is caused by the larval stages of Echinococcus granulosus, results from the presence of one or more massive cysts or hydatids, and can involve any organ, including the liver, lungs, heart, brain, kidneys, and long bones. Muscle hydatidosis is usually secondary in nature, resulting from spread of larval tissue from a primary site after spontaneous or trauma-induced cyst rupture or after release of viable parasite material during invasive treatment procedures. Primary muscle hydatidosis is extremely uncommon, because implantation at this site would require passage through the filters of the liver and lung. Intramuscular hydatid cyst can cause a variety of diagnostic problems, especially in the absence of typical radiologic findings. We present an unusual case of a primary hydatid cyst found in the popliteal fossa of the right knee of a 52-year-old woman, presenting as an enlarging soft-tissue tumor for 6 months associated with pain. The mass initially was diagnosed to be Backer′s cyst by ultrasonography, but later it was confirmed postoperatively through histopathological studies to be due to hydatid disease.

    A 21-year-old female patient recently diagnosed with severe hypothyroidism was found to have a large ovarian cyst. In view of the large ovarian cyst, she was advised to undergo elective laparotomy in the gynaecology department. She was further evaluated in our medical out-patient department (OPD), and elective surgery was withheld. She was started on thyroxine replacement therapy, and within a period of 4 months, the size of the cyst regressed significantly, thereby improving the condition of the patient significantly. This case report highlights the rare and often missed association between hypothyroidism and ovarian cysts. Although very rare, profound hypothyroidism that can cause ovarian cysts in an adult should always be kept in the differential diagnosis to avoid unnecessary ovarian surgery. Hypothyroidism should be considered in the differential diagnosis of adult females presenting with multicystic ovarian tumours.Adequate thyroid hormone replacement therapy can prevent these patients from undergoing unnecessary and catastrophic ovarian resection.Surgical excision should be considered only when adequate thyroid replacement therapy fails to resolve ovarian enlargement.In younger women with ovarian cysts, it is also desirable to avoid unnecessary surgery so as to not compromise fertility in the future.

    Eleven patients with sharply circumscribed round to ovoid renal cysts measuring 70-90 H on CT are reported. The cysts were hyperdense on unenhanced scans, measuring 30-60 H greater than the adjacent parenchyma, and either hypodense, isodense, or hyperdense on enhanced scans. Four patients had polycystic kidney disease; of the other 7 patients, the cysts were cortical in 6 and parapelvic in 1. Eight patients had a solitary cyst and 3 had multiple cysts. Sonography demonstrated internal echoes and/or lack of increased through-transmission in 6 patients. Pathological analysis was available in 6 cases and indicated a benign, hemorrhagic renal cyst. This hyperdense CT appearance is characteristic of some hemorrhagic renal cysts, though differentiation between benign and malignant cysts requires cyst puncture and/or surgery

    The differential between aneurysmal bone cysts and unicameral bone cysts usually is clear clinically and radiographically. Occasionally there are cases in which the diagnosis is not clear. Because natural history and treatment are different, the ability to distinguish between these two entities before surgery is important. The authors reviewed, in a blinded fashion, the preoperative magnetic resonance images to investigate criteria that could be used to differentiate between the two lesions. All patients had operative or pathologic confirmation of an aneurysmal bone cyst or unicameral bone cyst. The authors analyzed the preoperative magnetic resonance images of 14 patients with diagnostically difficult bone cysts (eight children with unicameral bone cysts and six children with aneurysmal bone cysts) and correlated these findings with diagnosis after biopsy or cyst aspiration and contrast injection. The presence of a double density fluid level within the lesion strongly indicated that the lesion was an aneurysmal bone cyst, rather than a unicameral bone cyst. Other criteria that suggested the lesion was an aneurysmal bone cyst were the presence of septations within the lesion and signal characteristics of low intensity on T1 images and high intensity on T2 images. The authors identified a way of helping to differentiate between aneurysmal bone cysts and unicameral bone cysts on magnetic resonance images. Double density fluid level, septation, and low signal on T1 images and high signal on T2 images strongly suggest the bone cyst in question is an aneurysmal bone cyst, rather than a unicameral bone cyst. This may be helpful before surgery for the child who has a cystic lesion for which radiographic features do not allow a clear differentiation of unicameral bone cyst from aneurysmal bone cyst.

    Full Text Available Dentigerous cysts are the second most common odontogenic cysts after radicular cysts and are most commonly seen in association with third molars and maxillary canines. Only 5% of dentigerous cysts involve supernumerary teeth, of which mesiodens is the most frequent type. This paper presents a case of dentigerous cyst associated with a mesiodens that caused a painless swelling in the upper lip of an 18-year-old female. The patient was treated surgically by enucleation of total cyst and surgical extraction of mesiodens under local anesthesia.

    Full Text Available Hydatid cyst is a zoonotic infection usually caused by Echinococcus granulosus. Hydatid cysts are most often localized in the liver and lungs. Isolated cases of hydatid cyst in soft tissue is very rare. The incidance of isolated soft tissue hydatid cyst is 2.3% in endemic areas. Medical treatment is successful in 30-40% of cases. The first choice of treatment is surgery, especially in atypical localization of hydatid cyst. We aimed to present our patient with ankle hydatid cyst, a rare case in the literature.

    Congenital rectal duplication cyst is a rare entity treated with surgical excision. Without treatment, a rectal duplication cyst may cause a variety of complications, most notably, transforming into a malignancy. We report on a 7-week-old girl who was found to have a rectal duplication cyst. The rectal duplication cyst was successfully excised laparoscopically. Rectal duplication cysts are rare alimentary tract anomalies generally discovered during childhood. Complications include symptoms arising from the cyst and the possibility of malignant degeneration. They are typically managed by surgical excision.

    1987-08-01

    Immunostaining with monoclonal antibodies was used to study and compare the cytokeratin content of odontogenic cysts and normal gingival epithelium. Two monoclonal antibodies, PKK2 and KA1, stained the whole epithelium in all cyst samples. In gingiva, PKK2 gave a suprabasal staining and KA1 reacted with all epithelial cell layers. Antibodies PKK1, KM 4.62 and KS 8.12 gave a heterogeneous staining in follicular and radicular cysts. In keratocysts and in gingiva PKK1 and KM 4.62 reacted mainly with basal cells and KS 8.12 gave a suprabasal staining. Antibodies reacting with the simple epithelial cytokeratin polypeptide No. 18 (PKK3, KS 18.18) recognized in gingiva only solitary cells compatible with Merkel cells. In a case of follicular ameloblastoma a distinct staining of tumor epithelium was revealed with these antibodies. In 2 follicular cysts, but not in other cyst types, a layer of cytokeratin 18-positive cells was revealed. KA5 and KK 8.60 antibodies, reacting exclusively with keratinizing epithelia, including normal gingiva, gave no reaction in radicular cysts, keratocysts and ameloblastoma. Two of the follicular cysts, were negative for PKK3 and KS 18.18, but reacted strongly with KA5 and KK 8.60. The present results show that odontogenic jaw cysts have distinct differences in their cytokeratin content. With the exception of some follicular cysts, they lack signs of keratinizing epithelial differentiation. Only follicular cysts appear to share with some types of ameloblastoma the expression of cytokeratin polypeptide No. 18.

    Objective: To analyse our clinical experience with CT guided percutaneous renal cysts puncture and ethanol therapy. Methods: Five hundred and ten renal cysts in 445 patients were undergone CT guided percutaneous renal cysts puncture and ethanol therapy. Among the 445 cases, 385 cases had solitary renal cyst, 53 multiple renal cysts, and 7 polycystic kidneys. The renal cysts varied in size from 1.9 to 13.5 cm in diameter. The amount of aspirated fluid varied from 3 to 780 ml. A 18-21 gauge aspiration needles were used for all patients. A 25.0% cyst volume replacement with 99.7% ethanol was approved to be appropriate. Results: 427 renal cysts in 396 patients were followed up by computed tomographic (CT) or ultrasound for less than 3 months to more than one year duration. The curative effective rate and disappearance rate of the renal cystic cavity in solitary renal cysts were 97% and 82%, respectively. In multiple renal cysts, the corresponding values were 95% and 79%. In polycystic kidneys, the curative rate was 67%. The complications such as local abdominal pain (28 cases) and hematuria (four cases) were observed in this series. There were no fatal complications. Conclusions: CT guided percutaneous renal cyst puncture and ethanol therapy is an useful procedure for the treatment of solitary renal cysts and multiple renal cysts

    To evaluate the frequency of a paratracheal cyst on CT in an adult, and to compare the degree of loculation and the patient's age with the longest diameter of the air cysts. Of 1520 patients, who underwent a CT scan, 41 patients with paratracheal cysts were enrolled in this study. There were 26-males and 15 females, whose ranged from 24 to 82 years (mean, 59.8). The CT findings were evaluated to determine the relationship between the degree of loculation and the longest diameter of the air cysts. Another tracheal diverticula or an air cyst, as well as the tracheal communication were also evaluated. The longest diameter of the paratracheal air cysts was 1 cm (ρ = 0.043). The paratracheal air cysts 2 cm were multilocular. Four patients had another small tracheal diverticula, and one patient had another small paratracheal air cyst. Tracheal communication was observed in 7 patients (17%). The frequency of paratracheal air cysts in adults undergoing a CT scan was 2.7%. The longest diameter of the paratracheal air cysts was associated with the patient's age. The shape of air cysts became more multilocular as the longest diameter of the paratracheal air cysts increased. Another small tracheal diverticula or air cysts were observed in 12% of patients

    An amygdaloid cyst is a rare high laterocervical cystic tumor arising from the second branchial cleft. It accounts for 2% of laterocervical tumors and up to 85% of second branchial cleft abnormalities [1]. The incidence of intracystic squamous cell carcinoma ranges from 4 to 22% [2]. The diagnosis of primary carcinoma or intracystic metastasis is a controversial issue. We report a rare case of degenerate amygdaloid cyst meeting the diagnostic criteria for intracystic squamous cell carcinoma determined by Martin and Khafif. A 73-year-old female patient consulted for a left cervical swelling in 2010; the diagnosis was an amygdaloid cyst. She had a history of squamous cell carcinoma of the hard palate (T1NoMo) surgery and radiation therapy in 2009, without recurrence. Three years later, the swelling increased to a large size without any cervical node involvement. An exploratory cervicotomy with histological study revealed intracystic squamous cell degeneration. Primary squamous cell carcinoma location in the wall of an amygdaloid cyst is extremely rare and a highly controversial issue. The challenge is to be able to discriminate between a cystic metastasis of squamous cell carcinoma of the aerodigestive tract and a primary squamous cell carcinoma located in the wall of an amygdaloid cyst. Martin and Khafif defined specific criteria to confirm the diagnosis of primary branchiogenic carcinoma. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

    Full Text Available The purpose of this study is to describe transient macular cysts in an infant and correlate their occurrence with normal development events. A newborn Caucasian girl presented with a protruding corneal mass in her left eye at birth. She underwent a complete ophthalmic examination. A keratinized staphylomatous malformation involving the entire cornea and precluding further visualization of the anterior and posterior segment was observed in the left eye. Spectral domain optical coherence tomography (SD-OCT of the right eye performed when the child was approximately 6-week-old had revealed an unexpected finding of macular cysts involving the inner nuclear and outer retinal layers. Corneal transplant in the left eye was performed a month later. Ocular examination under anesthesia just prior to surgery revealed normal intraocular pressure, anterior segment and retina in the right eye. SD-OCT was normal in both eyes and showed complete resolution of the cysts in the right eye. The patient had not been on any medications at that time. Although clinical retinal examination might be unremarkable, SD-OCT may reveal cystic spaces in the macula. In the absence of conditions known to be associated with macular edema, transient macular cysts may arise due to a developmental incompetence of the blood-retinal barrier or may represent transient spaces created during normal migration of retinal cells. Further study is warranted to delineate the entity of transient macular cysts in infancy.

    The pathogenesis of cysts that arise in the jaws is still not certain, and the underlying mechanisms of epithelial proliferation are not fully understood. Cysts of the jaw may involve a reactive, inflammatory, or neoplastic process. Cytogenetics, the study of the number and structure of chromosomes, has provided valuable information about the diagnosis, prognosis, and targeted treatment in many cancers, including oral squamous cell carcinoma. Cytogenetics can also provide information about the possible aetiology or neoplastic potential of a lesion, though to our knowledge no studies of this technique have been used for cysts in the jaws. In this pilot study we used cytogenetics in a series of 10 cysts (3 radicular, 4 dentigerous, 2 of the nasopalatine duct, and 1 dermoid). In all cases we found normal karyotypes. Further work and larger numbers are needed for a definitive study, but we can hypothesise from this pilot study that these cysts do not have cytogenetic aberrations and so have no neoplastic potential.

The patient was treated by laminectomy and excision of the cyst. Tarlov cysts (sacral perineural cysts are nerve root cysts found most commonly in the sacral roots, arising between the covering layer of the perineurium and the endoneurium near the dorsal root ganglion. The incidence of Tarlov cysts is 5% and most of them are asymptomatic, usually detected as incidental findings on MRI. Symptomatic Tarlov cysts are extremely rare, commonly presenting as sacral or lumbar pain syndromes, sciatica or rarely as cauda equina syndrome. Tarlov cysts should be considered in the differential diagnosis of patients presenting with these complaints.

    CT and MR images of 8 patients with supratentorial arachnoid cyst complicated by subdural hematoma were studied and compared with those of 8 patients who developed nontraumatic subdural hematoma without arachnoid cyst. Ot the 8 patients with supratentorial arachnoid cyst, CT and MR disclosed temporal bulging and/or thinning of the temporal squama in all 6 patients with middle fossa arachnoid cysts, and the thinning of the calvaria was evident in another patient with a convexity cyst. Calvarial thinning at the site corresponding to interhemispheric arachnoid cyst was clearly depicted on coronal MR images. In contrast, none of the 8 young patients with nontraumatic subdural hematoma without arachnoid cyst had abnormal calvaria. Temporal bulging and thinning of the overlying calvaria were identified as diagnostic CT and MR features of arachnoid cyst with complicating intracystic and subdural hermorrhage. Radiologists should be aware of this association and should evaluate the bony structure carefully. (orig.)

    Supratentorial endodermal cysts are very rare pathological entities. Their pathoembryology is largely unknown and they can represent a diagnostic challenge. A research performed on the PubMed database in December 2010, to screen for supratentorial endodermal cyst studies, demonstrated that since 1960 only 31 supratentorial endodermal cysts have been described in the literature, including our case: a 42-year-old woman with a parasellar endodermal cyst. These lesions are usually benign. As with other types of brain cysts, the signs and symptoms caused by supratentorial endodermal cysts are mainly linked to the compression or irritation of surrounding neural structures. Upon neuroimaging examination, they typically appear as a round or lobulated mass. The signal intensity may vary depending on the protein content of the cyst. The majority of reported supratentorial endodermal cysts were completely excised with good or excellent results. Incomplete excision can result in an increased risk of recurrence, infection, and dissemination. Georg Thieme Verlag KG Stuttgart · New York.

    2011-01-01

    The aim of this case study is to present effectiveness of percutaneous drainage as a treatment option of ruptured lung and liver hydatid cysts. A 65-year-old male patient was admitted with complicated liver and lung hydatid cysts. A liver hydatid cyst had ruptured transdiaphragmatically, and a lung hydatid cyst had ruptured both into bronchi and pleural space. The patient could not undergo surgery because of decreased respiratory function. Both cysts were drained percutaneously using oral albendazole. Povidone–iodine was used to treat the liver cyst after closure of the diaphragmatic rupture. The drainage was considered successful, and the patient had no recurrence of signs and symptoms. Clinical, laboratory, and radiologic recovery was observed during 2.5 months of catheterization. The patient was asymptomatic after catheter drainage. No recurrence was detected during 86 months of follow-up. For inoperable patients with ruptured liver and lung hydatid cysts, percutaneous drainage with oral albendazole is an alternative treatment option to surgery. The percutaneous approach can be life-saving in such cases.

    Baker's cysts are fluid distensions of the gastrocnemius-semimembranosus bursa and are the most common cystic lesion around the knee. Typically cysts enlarge along intermuscular planes around the knee. We report three cases in which the expanding cyst did not respect these planes and dissected along an intramuscular route as confirmed by MR imaging. Such behaviour by Baker's cysts is hitherto unreported in the literature. Possible mechanisms to account for this phenomenon are discussed. (orig.)

Its ability to convert into dormant and highly resistant cysts form limits effectiveness of available therapeutic agents and presents a pivotal challenge for drug development. During the cyst stage, Acanthamoeba is protected by the presence of hardy cyst walls, comprised primarily of carbohydrates and cyst-specific proteins, hence synthesis inhibition ...

    Periapical cyst is a slow growing dental cyst, which is discove­ red on routine intraoral radiograph or cause localized intra­ osseous jaw swelling. It is typically found at root apex of the involved tooth and is discovered on routine radiography. This paper reports a rare presentation of periapical cyst. The cyst was localized in the premaxillary subcutaneous tissue, causing diagnostic difficulty. The steps in diagnosis of the lesion are also discussed

  5. Liesegang rings in renal cyst fluid.

    1990-01-01

    Peculiar ring-like structures identified as Liesegang rings (LRs) were found in renal cyst fluid from three patients with benign renal cysts. They ranged in size from 5 to 820 mu. Most had a double-layer outer wall with equally spaced radial cross-striations and an amorphous central nidus. Special stains were performed in one case, and the results are discussed. Reports of LRs in cystic or inflamed tissues have recently appeared in the literature. Some LRs have been mistaken for eggs or mature components of the giant kidney worm, Dioctophyma renale. We propose that cytologic assessment of renal cyst fluid in conjunction with histologic examination decreases the likelihood of misdiagnosis of LRs.

    Full Text Available The objective of this study was to describe a case of a lymphoepithelial cyst in the palatoglossus arch. A 16-years-old black man said that he was observed a lesion in his mouth. On the physical exam, a pedicled, consistent, smooth surface 1.5 x 1 cm lesion, similar in color to the adjacent mucosa, was found. The lesion was surgically removed and the microscopic exam showed mucosal fragments with pedicled lesion; the cystic cavity sometimes lined with pseudostratified cylindrical epithelium and others with stratified squamous flat interface of the epithelium. Around the cyst, a well-delimited mass of lymphoid tissue, presenting lymphoid follicles, was also seen. Lymphoepithelial cyst has clinical characteristics similar to those of others lesions that occur in the oral cavity. The diagnosis should be based on conservative biopsy, with total removal of lesion.

  7. Nasolacrimal drainage system cyst in an adult.

    Yamasoba, T; Sugimura, H

    1996-01-01

    A cyst of the nasolacrimal drainage system (NLDS) is rare in an adult. We report a case in a 29-year-old man of a mucous retention cyst of the NLDS, which appeared 2 years after the patient developed dacryocystitis coincident with an aggravation of chronic sinusitis. The lesion was successfully managed by removing the bony wall of the NLDS at the interface with the ethmoid and nasal cavity, as well as the membranous closure of the ostium of the common canaliculus. We speculate that the cyst development might have been initiated by inflammatory change such as mucosal adhesion in the NLDS resulting from the spread of secondary infection from the sinonasal tract.

    1997-01-01

    Lumbar and intraneural synovial cysts are uncommon lesions. although their incidence has increased since the introduction of MRI. The authors describe the results of a study comprising 23 patients with synovial cyst (5 lumbar, 19 intraneural). Neuroradiological investigations included CT scan and MRI; however, it was not always possible to diagnose the nature of the lesion. In 18 cases the lesion was removed totally including its capsule; in the other 5 cases it was removed subtotally. Seven of the 23 patients presented a total remission of symptoms/signs, 11 improved and 5 remained unchanged. The importance of treating synovial cysts as radically as possible is discussed together with their most significant clinical and neuroradiological aspects. (author)

    2013-01-01

    Full Text Available Hydatid disease is an ancient endemic parasitic infestation caused by Echinococcus granulosus, which results in the formation of hydatid cysts in various parts of the body, the liver, and lungs being the most common sites. However, in 15% to 20% of the cases it may occur in unusual sites. We report a 25-year-old male patient who presented with clinical features similar to scrofuloderma in the axillary region but confirmed from histological examination to have hydatid cyst. This case highlights the uncommon site of hydatid cyst and unusual clinical and histopathological features along with the fact that it should be kept in differential diagnosis of nodules and sinuses in the axillary region. The treatment of choice is excision along with combination of albendazole and praziquantel.

    Enteric duplication is a rare developmental malformation in people, dogs and cats. The purpose of the present report is to describe the first case of a rectal duplication cyst in a 7-year-old domestic shorthair cat presenting for acute constipation and tenesmus. On rectal palpation a spherical mass compressing the lumen of the rectum could be felt in the dorsal wall of the rectum. A computed tomography (CT) scan confirmed the presence of a well demarcated cystic lesion in the pelvic canal, dorsal to the rectum. The cyst was surgically removed via a perineal approach. No communication with the rectal lumen could be demonstrated. Histopathological examination was consistent with a rectal duplication cyst. Clinical signs resolved completely after excision of this conjoined non-communicating cystic rectal duplicate. Copyright © 2010 ISFM and AAFP. Published by Elsevier Ltd. All rights reserved.

    We present a 29-year-old woman who was admitted to the emergency department with shortness of breath. Using echocardiography, a giant multi-cystic mass was detected in the right ventricle, attached to the septal leaflet of the tricuspid valve and basal portion of the interventricular septum. Serologic tests (hydatid cyst antibody) confirmed Echinococcus infection. Lung computed tomography with intravenous contrast showed involvement of the pulmonary vasculature. The patient underwent cardiac surgery and the large cardiac cyst and the one in the right pulmonary artery branch were both removed. The tricuspid valve was also replaced by a bioprosthetic one. Albendazole was started preoperatively and was continued for six months after surgery. The patient recovered uneventfully and was followed up for one year. This is a report of a rare case of a very large cardiac hydatid cyst complicated by pulmonary embolism with attachments to both the tricuspid valve and interventricular septum.

  13. Intracranial neurenteric cyst traversing the brainstem

    Directory of Open Access Journals (Sweden)

    Jasmit Singh

    2015-01-01

    Full Text Available Neurenteric cysts (NECs, also called enterogenous cysts, are rare benign endodermal lesions of the central nervous system that probably result from separation failure of the notochord and upper gastrointestinal tract. Most frequently they are found in the lower cervical spine or the upper thoracic spine. Intracranial occurrence is rare and mostly confined to infratentorial compartment, in prepontine region [51%]. Other common locations are fourth ventricle and cerebellopontine angle. There are few reports of NEC in medulla or the cerebellum. Because of the rarity of the disease and common radiological findings, they are misinterpreted as arachnoid or simple cysts until the histopathological confirmation, unless suspected preoperatively. We herein report a rare yet interesting case of intracranial NEC traversing across the brainstem.

  14. Huge Thornwaldt's Cyst: A Case Report

    2006-10-01

    Full Text Available Thornwaldt's bursa, also known as nasopharyngeal bursa, is a recess in the midline of the nasopharynx that is produced by persistent notochord remnants. If its opening becomes obstructed, possibly due to infection or a complication from adenoidectomy, a Thornwaldt's cyst might develop. Here, we present a 53-year-old man who complained of nasal obstruction that had progressed for 1 year. Nasopharyngoscopy showed a huge nasopharyngeal mass. Thornwaldt's cyst was suspected. Magnetic resonance imaging showed a lesion measuring 3.6 × 3.4 cm, intermediate on T1-weighted and high signal intensity on T2-weighted imaging, neither bony destruction nor connection to the brain. The patient underwent endoscopic surgery for this huge mass. Afterwards, his symptoms improved significantly. We present the treatment and differential diagnosis of a nasopharyngeal cyst.

    1997-01-01

    A three-year-old male Siberian Husky dog was referred to the Veterinary Teaching Hospital in Osaka Prefecture University with a complaint of difficulty in expelling the stools. By rectal examination, a mass as big as a fist could be detected occupying the cavum pelvis. Radiographically the mass had a thin bony shell bulging from the pubic periosteum. In the shell, radiolucent trabeculation gave the area a ''soap bubble'' appearance. The cut surface of the removed mass showed a honeycomb-like pattern constituted of some small loculate bony cysts. These cysts were separated from each other by a fibrous or bony trabeculae with blood-filled vascular channels or sponge-like structures. From clinical and pathological findings, this mass was diagnosed as a pelvic aneurysmal bone cyst. After surgery, the patient completely recovered without tenesmus

    Full Text Available Postoperative maxillary cyst is a quite rare delayed complication of surgical intervention associated with maxillary sinuses. It occurs many years after surgery. This paper describes a 54-year-old woman presenting with swelling of left cheek for seven-years duration. The orthopantomograph revealed a unilocular cystic radiolucency with well-defined margins in left maxillary sinus. In the computerized tomography, the cyst had a sclerotic wall with bony condensations. Aspiration cytology revealed many neutrophil leukocytes. Cyst was drained and enucleated. Histopathologically, it had a fibrous wall with inflammation and focal reactive bone formation and lined by a respiratory-type epithelium. In the clinical history, it is learned that she had a maxillary sinus surgery 8 years ago and the diagnosis was made considering the clinical and histopathological findings.

  17. Development of the yellow potato cyst nematode Globodera rostochiensis (Woll.) on potatoes after gamma irradiation of cysts

    Karnkowski, W.; Ignatowicz, S.

    1999-01-01

    Gamma irradiation inhibited the development of the yellow potato cyst nematode, Globodera rostochiensis (Woll.) Behrens when cysts containing juveniles in anabiosis were irradiated with a dose of 0.5 kGy or higher. A dose of 0.5 kGy reduced the infestation level and the density of females/cysts on root of infested plants. However, a few cysts were found on roots of plants grown in pots with soil treated with a dose of 3.0 kGy. Development of the second generation of the potato cyst nematode (= F1 cysts that originated from irradiated cysts) was much weaker than that of the parental generation. The F1 females and/or cysts were found only in the control and in the 0.5 kGy treatment in low numbers. (author)

    1994-01-01

    20 radicular cysts of primary teeth mimicking dentigerous cyst were reviewed. The following results were obtained. 1. The patients' age ranged from 7 to 14 years. Males(60%) were more involved than females (40%). 2. The mandible (85%) was affected more frequently than the maxilla (15%). The mandibular deciduous molar area (80%) was the most frequently involved. 3. The diameter of the cyst varied from 10 to 30 mm. 55% of permanent successors showed underdeveloped roots less than one-third. 4. The etiologic factors were pulp-treated teeth (65%), severe caries (20%), trauma (10%), deep amalgam filling (5%).

    1995-03-01

    Lymphoepithelial cysts are developmental, but their pathogenesis is unknown. The classical explanation is that they are derived from remnants of the branchial arches or clefts. This has been disputed, and it is likely that most arise from epithelium, possibly of tonsillar or salivary origin, that becomes entrapped by lymphoid tissue. This report describes a lymphoepithelial cyst in a 29-year-old man. The cyst was situated on the right side of the floor of the mouth adjacent to the lingual frenum. Its appearance supports both branchiogenic and the entrapment theories.

    2018-03-01

    Conclusions: S-NC are rare and challenging lesions. The radiological features are nonspecific, and it is difficult to differentiate enterogenous cysts from other cystic lesions such as arachnoid cyst, epidermoid or glioependymal cyst. In cases with mass effect and refractory symptoms, surgical removal is indicated, including liquid drainage, capsule removal and cisternal communication. Resection of these lesions is associated with favorable outcomes.

  14. Primary pelvic hydatic cyst mimicking ovarian carcinoma

    Directory of Open Access Journals (Sweden)

    Faruk Abike

    2011-05-01

    Full Text Available Hydatic cyst is an illness that appears in consequence of the cystic form of small strap-shaped worm Echinococcus granulosis. Frequently, cysts exist in the lungs and liver. Peritoneal involvement is rare, and generally occurs as a result of second inoculation from rupture of a liver-located hydatic cyst. Primary ovarian hydatic cyst is very rare. A 56-year-old female patient was admitted to Emergency Service with the complaint of stomachache and swollen abdomen. From ultrasonographic examination, a right ovarian 52 × 45-mm heterogeneous semi-solid cystic mass and right hydronephrosis were detected. As a result of the tomographic examination, the right ovarian growth was judged to be a 60 × 45-mm lobule contoured, septal, heterogeneously cystic mass (ovarian carcinoma. Depending on these indicators and with the diagnosis of ovarian carcinoma, laparotomy was planned. During the observation, a mass that compressed on the right ureter and dilatation in the right ureter were determined. The mass was approximately 6 cm long and smoothly contoured, including widespread adhesions, and also obliteration of the pouch of Douglas. The mass was excised and total abdominal hysterectomy and bilateral salpingo-oopherectomy performed. After a pathological examination, hydatid cyst was diagnosed. Although pointing at the issue of the distinctive diagnosis of pelvic and peritoneal mass, it should be realized that the existence of primary peritoneal and pelvic involvement of the hydatic cyst is generally a result of the second inoculation, and is also more common in regions in which Echinococcus granulosa is endemic and livestock production is prevalent.

  15. Multiple myxoid cysts secondary to occupation.

    Science.gov (United States)

    Connolly, M; de Berker, D A R

    2006-05-01

    We report the case of a 50-year-old woman who presented with eight digital myxoid cysts (DMCs) involving the fingers of both hands. They developed within 12 months of the patient starting a job that involved pushing a garment into an embroidery mould, thus exerting a downward force on the fingertips. The pressure exerted from this force could have potentially damaged the joint synovial capsule, leading to rupture and loss of synovial gel, thus inducing myxoid cysts. This case suggests that DMCs may be related to occupation, and to our knowledge, this is only the second reported case of occupationally induced DMCs.

    Hydatid disease, although known to occur in most body areas, is extremely rare in the female reproductive system. There are different modes of presentation for the disease; however, we report and discuss a case presented with cystic vesicles passing through the vagina, which is considered as a rare presentation for secondary involvement of the uterus and both ovaries. We confirmed diagnosis with radiological examinations and serological tests. We operated on the patient, and studied the excised cysts microscopically. The gynecologist should be aware of hydatid cyst when vaginally passing a grape like vesicle is presented by the patient. (author)

    Random gunfire deposited a bullet in the proximal tibial metaphysis of a 9-year- old girl. The wound was not incapacitating and was treated conservatively. Within 17 months, soreness developed in the proximal leg, and radiography revealed a large unicameral cyst within which the bullet freely tumbled. Eventually, fear of impending fracture prompted further radiography, computed tomography, surgical intervention and pathological examination of the cyst wall. We believe this is only the second description in the English-language literature of this rare sequence of events. (orig.)

    We present a case of plateau iris and glaucoma due to multiple unilateral iridociliary cysts. The patient was treated with iridotomy Nd: YAG laser and 360° iridoplasty, without achieving pressure control. Phacoemulsification improved the hypertension. Dynamic gonioscopy and OCT of the anterior chamber was also performed before and after treatment. Iridociliary cysts are a benign condition that can cause iris plateau configuration, and can produce a difficult to treat ocular hypertension. Cystotomy, peripheral iridoplasty, and other treatments have been proposed. Copyright © 2014 Sociedad Española de Oftalmología. Published by Elsevier España, S.L.U. All rights reserved.

    A lady aged 26 years reported with a 2 months history of fever, upper abdominal pain and weight loss. Her abdominal ultrasonographic scan revealed a complex cystic mass in left lobe of liver suggestive of hydatid cyst that was confirmed on magnetic resonance imaging of abdomen and magnetic resonance cholangiopancreatogram. With strong suspicion of a hydatid cyst, endoscopic retrograde cholangiogram was performed which confirmed the diagnosis. During the procedure, hydatid membranes protruding from the papilla were removed after sphincterotomy. She was put on albendazole 400 mg twice daily after the procedure and showed a remarkable clinical improvement. (author)

    Goltz-Gorlin syndrome presents with multiple basal cell carcinomas, odontogenic keratocysts, and cutaneous cysts, among other manifestations. The cutaneous cysts have been described as both epidermoid cysts and keratocysts but were not further characterized. Light microscopic examinations were made on 23 cutaneous cysts in 4 patients associated with Goltz-Gorlin syndrome located on extremities, face, trunk, palms, and soles and compared with nonsyndromic vellus hair cysts, steatocystomas, and hybrid cysts. Twenty-one of the syndromic cysts revealed alternating infundibular-like and steatocystoma-like squamous epitheliums in varying proportions. The cysts were lined by both smooth and corrugated squamous epithelium. The horny layer was composed by alternating areas of thin, lamellate, and compact eosinophilic keratin. Only 2 cases showed an exclusive steatocystoma-like type of epithelium very similar to odontogenic keratocysts. Sebaceous glands and follicular structures were absent. There were no differences between palmar and plantar cysts and other anatomic locations. The ultrastructural findings in syndromatic cysts confirmed variable expression of keratohyalin granules. Only 3 of 6 cases of nonsyndromic hybrid cysts showed overlapping features with syndromic cysts. Immunohistochemical profiling of keratin, involucrin, filaggrin, loricrin, and BCL-2 expression in syndromatic cysts showed exclusive positivity of K19 and continuous staining for BCL-2. In summary, 2 types of cutaneous cysts are characteristic of Goltz-Gorlin, irrelevant of their anatomic location, namely steatocystoma-like and more frequently hybrid-like. The diagnosis of syndromic hybrid-like cysts should be considered whenever infundibular and steatocystoma differentiation alternate and overlap. Altogether, these findings in epithelial cysts may raise the suspicion of Goltz-Gorlin as an underlying cause.

    A new classification system for congenital laryngeal cysts based on the extent of the cyst and on the embryologic tissue of origin is proposed. Retrospective chart review. The charts of 20 patients with either congenital or acquired laryngeal cysts that were treated surgically between 1987 and 2002 at the Hospital for Sick Children, Toronto were retrospectively reviewed. Clinical presentation, radiologic findings, surgical management, histopathology, and outcome were recorded. A new classification system is proposed to better appreciate the origin of these cysts and to guide in their successful surgical management. Fourteen of the supraglottic and subglottic simple mucous retention cysts posed no diagnostic or therapeutic challenge and were treated successfully by a single endoscopic excision or marsupialization. The remaining six patients with congenital cysts in the study were deemed more complex, and all required open surgical procedures for cure. On the basis of the analysis of the data of these patients, a new classification of congenital laryngeal cysts is proposed. Type I cysts are confined to the larynx, the cyst wall composed of endodermal elements only, and can be managed endoscopically. Type II cysts extend beyond the confines of the larynx and require an external approach. The Type II cysts are further subclassified histologically on the basis of the embryologic tissue of origin: IIa, composed of endoderm only and IIb, containing endodermal and mesodermal elements (epithelium and cartilage) in the wall of the cyst. A new classification system for congenital laryngeal cysts is proposed on the basis of the extent of the cyst and the embryologic tissue of origin. This classification can help guide the surgeon with initial management and help us better understand the origin of these cysts.

    Liver cysts are divided into congenital and acquired. Congenital cystic lesions include polycystic liver disease, simple cysts, duct related and ciliated hepatic foregut cysts. Acquired cystic lesions are divided into infectious and non-infectious. The infectious cysts are the hydatid cyst, the amoebic abscess, and the pyogenic abscess, whereas the non-infectious cysts are neoplastic cysts and false cysts. While modern medicine provides a lot of minimally invasive therapeutic modalities, there has emerged a pressing need for understanding the various types of liver cysts, the possible minimal therapeutic options along with their indications and complications. We aim is to clarify the role of minimally invasive techniques in the management of hepatic cysts. A literature review was performed using the MEDLINE database. The search terms were: liver cyst, minimally invasive, laparoscopic, percutaneous, drainage and fenestration. We reviewed 82 English language publications articles, published until October 2017. Minimally invasive management of liver LC is an emerging field including many therapeutic modalities ranging from the percutaneous aspiration of pyogenic abscesses to laparoscopic hepatectomy for hepatic cystadenomas. The most used techniques are percutaneous drainage, laparoscopic fenestration, and laparoscopic hepatectomy. The application of the various minimally invasive approaches, as well as their indication and complications, depend on the type of the cystic lesion, its size and its position in the liver. Percutaneous drainage is mostly used in simple cysts, hydatid cysts, pyogenic abscesses and bilomas. Laparoscopic fenestration is mostly used in simple cysts and polycystic liver disease. Finally, laparoscopic hepatectomy is mostly used in polycystic liver disease, hydatid cysts, and cystadenomas.

    Full Text Available The category B agent of bioterrorism, Entamoeba histolytica has a two-stage life cycle: an infective cyst stage, and an invasive trophozoite stage. Due to our inability to effectively induce encystation in vitro, our knowledge about the cyst form remains limited. This also hampers our ability to develop cyst-specific diagnostic tools.Three main aims were (i to identify E. histolytica proteins in cyst samples, (ii to enrich our knowledge about the cyst stage, and (iii to identify candidate proteins to develop cyst-specific diagnostic tools.Cysts were purified from the stool of infected individuals using Percoll (gradient purification. A highly sensitive LC-MS/MS mass spectrometer (Orbitrap was used to identify cyst proteins.A total of 417 non-redundant E. histolytica proteins were identified including 195 proteins that were never detected in trophozoite-derived proteomes or expressed sequence tag (EST datasets, consistent with cyst specificity. Cyst-wall specific glycoproteins Jacob, Jessie and chitinase were positively identified. Antibodies produced against Jacob identified cysts in fecal specimens and have potential utility as a diagnostic reagent. Several protein kinases, small GTPase signaling molecules, DNA repair proteins, epigenetic regulators, and surface associated proteins were also identified. Proteins we identified are likely to be among the most abundant in excreted cysts, and therefore show promise as diagnostic targets.The proteome data generated here are a first for naturally-occurring E. histolytica cysts, and they provide important insights into the infectious cyst form. Additionally, numerous unique candidate proteins were identified which will aid the development of new diagnostic tools for identification of E. histolytica cysts.

    Epidermal inclusion cysts, the most common type of simple epithelial cyst, are typically well-encapsulated, subepidermal and mobile nodules. They may occur anywhere, but are mostly found on the scalp, face, neck, trunk, and back. Less than 10% of epidermal inclusion cysts occur on the extremities, and even fewer are found on the palms, soles, and breasts. If epidermal inclusion cysts rupture, foreign body reaction, granulomatous reaction or abscess formation could follow. We described here the sonographic findings of ruptured epidermal inclusion cyst of the right axilla in a 33-year-old woman who presented with a palpable axillary mass forming an inflammatory abscess

    The most common cause of echinococcosis in humans is Echinococcus granulosus. Although hydatid cyst is most frequently localized in liver (more than 65% of cases) and lung (25%) by means of portal and systemic circulation, it may involve other tissues and organs. Cardiac hydatid cysts account for only 0.5%-2% of all hydatid cysts, even in endemic areas. Of all cardiac hydatid cysts, the left ventricle accounts for 60%, right ventricle 10%, pericardium 7%, pulmonary artery 6%, left atrial appendage 6%, and interventricular septum 4%.

    Congenital urachal abnormalities are more common in children, but urachal cyst is more frequently seen in adults. Infection within a cyst produces significant symptoms, which may explain the fact that three times as many infected cysts as uninfected urachal cysts are detected in adults. We report here on a case of infected urachal cyst with a fish bone and also the fistular formation between the ileum and urachus in a 63-year-old male with a history of urinary frequency and a tender mass at the lower abdominal quadrant.

    Duplication cysts of the gastrointestinal tract are rare congenital abnormalities. Ectopic gastric mucosa, which can be found in duplications, may cause peptic ulceration, gastrointestinal bleeding or perforation. We report a 1-year-old boy with a perforated ileal duplication cyst with haemorrhagic pseudocyst formation caused by peptic ulceration of the duplication cyst. It presented a snowman-like appearance consisting of a small, thick-walled, true enteric cyst and a large, thin-walled haemorrhagic pseudocyst on US and CT. It is an unusual manifestation of a duplication cyst, which has not been reported in the English language literature. (orig.)

    Large adrenal cysts usually occur in the fifth and sixth decades of a patient's life but are rare in the first two decades. This paper presents the clinical, cross-sectional imaging, surgical, pathological and follow-up data of three teenage girls with large adrenal cysts. Two had vague upper abdominal pain and, in the other, the cyst was found incidentally. The cysts were surgically removed in two patients, while in the third, follow-up imaging has shown no change in the cyst over a 4-year period, suggesting that conservative management is a reasonable option.

    We have not known surgical indications for incidental Rathke`s cleft cysts, because of our lack of knowledge about their natural history. In this study, we investigated whether symptomatic Rathke`s cleft cysts have any characteristic features in magnetic resonance (MR) signal intensities, and analyzed their relation to clinical manifestations and to patterns of suprasellar expansion. MR signal intensities on T1-weighted (T1W) and T2-weighted (T2W) images were categorized into 3 types in 78 cases including our 9 cases; type I, low signal intensity on T1W images and hyperintensity on T2W images in 25 cases; type II, hyperintensity on both T1W and T2W images in 20; and type III, low intensity on T2W images, in other 33. Patients of type I signal intensities presented with significantly high percentage of large cysts compressing the third ventricle than patients with other types. The patients of type I signal intensities also frequently had visual disturbance. Patients in type II showed significantly less percentage of large cysts. Anterior pituitary dysfunction was observed more often in patients of type II and III than patients of type I. We conclude that Rathke`s cleft cysts with MR signal intensity like cerebrospinal fluid (CSF) are slowly growing, and are frequently diagnosed as large cysts associated with visual disturbance. The patients with other types of MR signal intensities may suffer pituitary dysfunction or other symptoms before the cysts compress the hypothalamic region. The assessment of MR signal intensities may contribute in predicting clinical progression in patients with Rathke`s cleft cysts. (author)

    Paraovarian cysts are very uncommon in children To present a case of giant paraovarian cyst case in a child and its management using a modified laparoscopic-assisted technique A 13-year-old patient with a 15 day-history of intermittent abdominal pain, located in the left hemiabdomen and associated with progressive increase in abdominal volume. Diagnostic imaging was inconclusive, describing a giant cystic formation that filled up the abdomen, but without specifying its origin. Laboratory tests and tumor markers were within normal range. Video-assisted transumbilical cystectomy, a modified laparoscopic procedure with diagnostic and therapeutic intent, was performed with a successful outcome. The histological study reported giant paraovarian cyst. Cytology results were negative for tumor cells. The patient remained asymptomatic during the postoperative follow-up. The video-assisted transumbilical cystectomy is a safe procedure and an excellent diagnostic and therapeutic alternative for the treatment of giant paraovarian cysts. Copyright © 2015.

    2014-01-01

    Full Text Available Background. Orbital epidermoids form a rare pathological entity that is separate from dermoid cysts. They have variable clinical and radiological presentations and they should be considered in the differential diagnosis of orbital cystic lesions. This work describes the various clinical and radiological presentations of 17 cases of epidermoid cysts and the surgical outcome. Method. A prospective interventional study was conducted on 17 patients diagnosed with epidermoid cysts. Patients’ symptoms and signs were recorded; CT scan was done for all patients. All lesions were removed through anterior orbitotomy and histopathological diagnosis confirmed. Results. Mean age of patients was 16.3 years ±  10.54. Main complaints were lid swelling, masses, ocular dissimilarity, chronic pain, and ocular protrusion. Clinical signs varied from lid swelling and masses in all cases to proptosis, globe displacement, limitation of ocular motility, and scars. Radiological findings ranged from homogenous hypodense masses (58.8% to homogenous radiolucent (17.6% and heterogenous masses (23.5%. No recurrences following surgeries were reported throughout the follow-up (mean 18.8 months ±  0.72. Conclusion. Deep orbital epidemoid cysts are a separate entity that can behave like deep orbital epidermoid; however, they usually present at a relatively older age. They can be associated with increased orbital volume but not necessarily related to bony sutures.

    Potato cyst nematode (PCN) is responsible for losses in potato production totalling millions of euros every year in the EC. It is important for growers to know which species is present in their land as this determines its subsequent use. The two species Globodera pallida and Globodera rostochiensis can be differentiated using an allele-specific PCR.

    1988-01-01

    We discussed six cases with dorsal cyst malformations listing their neuroradiological observations and proposed to differentiate between the holosphere and hemisphere as defined by Yokota (1984). The cases were divided into holospheric and hemispheric groups depending on the continuity of their frontal lobe midlines. Cases 1, 2 and 3 were placed in the holospheric group because of their unseparated frontal lobe sbeneath the partially formed anterior interhemispheric fissures. Cases 4, 5 and 6 were grouped in the hemisphere due to the completion of the interhemispheric fissures. There has been a tendency in recent years for most cases of cerebral malformations having an endogenous dorsal cyst with monoventricular configuration to be diagnosed as holoprosencephaly. However, we believe that only patients who have a dorsal cyst in the holospheric brain should be included, and the others in the hemispheric brain, which is capable of completing hemispheric cleavage, should not. Therefore, we emphasize the importance of correctly identifying the holospheric state in the dorsal cyst malformations for diagnosing holoprosencephaly. (author)

    The aim of this study was to assess the magnetic resonance imaging (MRI) characteristics of 13 benign complex renal cysts using T1 and T2-weighted images and contrast-enhanced images. The results have been compared to CT and ultrasonographic findings in all cases and correlated with histopathologic datas in 12 cases. Five groups have been defined according to the MR features. Group 1: homogeneous low signal intensity on T1-weighted images and homogeneous high signal intensity on T2-weighted images mimicking simple cyst (n = 2); group 2: homogeneous high signal intensity on both T1 and T2-weighted images mimicking hemorrhagic cyst (n = 1); group 3: characterized by high signal intensity on T1-weighted images and fluid-iron level on T2-weighted images (n = 3); group 4: characterized by fluid-iron level on both T1 and T2-weighted images (n = 3); group 5: pseudotumoral feature: heterogeneous signal intensity and/or wall contrast enhancement (n = 3). Among the 13 indeterminate lesions on ultrasonography and CT, MRI was of diagnostic value in 8 cases, whereas the 5 remaining cases remained indeterminate on MR images. Our results suggest that MRI can be useful in the diagnosis of benign complex cyst of the kidney presenting as indeterminate cystic lesion on other modalities. (authors). 40 refs., 7 figs., 2 tabs

    This case describes a 10-year-old girl who developed a Ewing's sarcoma in her proximal fibula. The radiologic features mimicked those of a unicameral bone cyst. The presence of pain and the atypical location led to a prompt biopsy and the correct diagnosis. The mechanism of this unusual radiographic presentation is discussed. (orig.)

    Unicameral bone cysts of the pelvis are extremely rare. This study summarizes the clinical, radiologic and pathologic features of 16 cases. Patients ranged in age from nine to 69. Most lesions were in the anterior portion of the iliac wing; many appeared to be related to an open iliac crest apophysis. This suggests that the pathogenesis of unicameral bone cysts in this portion of the ilium is similar to that seen in the proximal humerus and the proximal femur. The correct diagnosis was made preoperatively in only five cases. This indicates that, although they are well documented, unicameral bone cysts of the pelvis remain a diagnostic problem. Patients received a spectrum of treatments from curettage to observation. There appeared to be no difference in the outcome after any form of treatment. Therefore, unicameral bone cysts of the pelvis can be managed conservatively. The choice to manage patients conservatively depends on making the correct diagnosis based on clinical history and imaging. The most effective imaging is a combination of plain radiographs, computed tomography (CT) and magnetic resonance imaging (MRI). PMID:16089077

    We present our experience in the management of choledochal cysts from 1999 to 2009. A retrospective review of all charts with a diagnosis of choledochal cysts in our institution in this ten-year period. Data was collated using Excel. A total of 17 patients were diagnosed with choledochal cyst: 9 females and 8 males. The average age at diagnosis was 28 months (range from 0 to 9 years). The most common presenting symptoms were obstructive jaundice 6 (35%) and abdominal pain and vomiting 4 (23%). Ultrasound (US) was the initial diagnostic test in all cases with 4 patients requiring further investigations. All patients underwent Roux-en-Y Hepaticojejunostomy. The average length of stay was 11 days. Patients were followed up with Liver Function Tests (LFTS) and US 4-6 weeks post-operatively. Three patients developed complications including post-op collection, high drain output requiring blood transfusion and adhesive bowel obstruction. Our overall experience with choledochal cyst patients has been a positive one with effective management and low complication rates.

    Full Text Available Background. Choledochal cyst is a rare abnormality. Its esti- mated incidence is of 1:100,000 to 150,000 live births. Todani et al. in 1981 reported the main objection for performing a simpler procedure, i.e., hepaticoduodenostomy, has been the risk of an “ascending cholangitis”. This hazard, however, seems to be exaggerated. Methods: A laparoscopic procedure was performed in 8 consecutive patients with choledochal cyst between January 2010 and Septem- ber 2012; 6 females and 2 males mean age was 8 years. Results. Abdominal pain was the main symptom in everyone, jaundice in 1 patient and a palpable mass in 3 patients. Lapa- roscopic surgical treatment was complete resection of the cyst with cholecystectomy and hepaticoduodenostomy laparoscopy in every patient. Discussion and conclusion. A laparoscopic approach to chole- dochal cyst resection and hepaticoduodenostomy is feasible and safe. The hepaticoduodenal anastomosis may confer additional benefits over hepaticojejunostomy in the setting of a laparoscopic approach. The creation of a single anastomosis can decrease operative time and anesthetic exposure.

    2010-01-01

    Objective: To analyze the characteristics of spinal meningeal cyst in low-field MRI and to discuss its classification, subtype, clinical presentation, and differential diagnosis. Methods: Forty-two patients (20 male, 22 female) were examined with sagittal T 1 -and T 2 -, axial T 2 -weighted MR imaging. Twelve patients were also examined with contrast-enhanced MRI. Results: The cysts were classified using Nakors' classification as type Ia extradural meningeal cysts (4 patients), type Ib sacral meningeal cysts (32), type II extradural meningeal cysts with spinal nerve root fibers (4), and type III spinal intradural meningeal cysts (2). All 42 spinal meningeal cysts had well-defined boundaries with low T 1 and high T 2 signal intensities similar to cerebral spinal fluid. In type Ia, the lesions were often on the dorsum of mid-lower thoracic spinal cord compressing the spinal cord and displacing the extradural fat. In type Ib, the lesions were in the sacral canal with fat plane between the cyst and dural sac. In type II, the lesions contained nerve roots and were lateral to the dural sac. In type III, the lesions were often on the dorsum of spinal cord compressing and displacing the spinal cord anteriorly. Conclusion: Low-field MRI can clearly display the spinal meningeal cyst. Types Ia and Ib spinal meningeal cysts had typical features and can be easily diagnosed. Types II and III should be differentiated from cystic schwannomas and enterogenous cysts, respectively.

    Full Text Available Background: Odontogenic cysts and tumors are lesions that tend to arise from the tooth apparatus or its remnants. Odontogenic cysts and tumors constitute an important aspect of oral maxillofacial pathology as they can be diagnosed in general dental practice. Aim: The purpose of this study was to evaluate the prevalence of odontogenic cysts and tumors diagnosed in the UAE and to compare the results with findings in the literature. Materials and Methods: Data of odontogenic cysts diagnosed between 1990 and 2010 were collected from the files of the Oral Pathology Laboratory and Oral Surgery Department of Tawam Hospital, UAE. Results: Most of the prevalent odontogenic cysts are radicular cysts (69.1% - followed by dentigerous cysts (7.9%. Among the odontogenic tumors, the most prevalent is odontoma (12.2% followed by ameloblastoma (2.9%. The middle and posterior mandible was the most common anatomic site for the formation of cysts and tumors. In fact, 93.4% of patients over 40 years presented with odontogenic cysts, whereas 6.3% presented with odontogenic tumor. Odontoma as odontogenic tumor was seen mostly in the first and second decades of life. Conclusion: The prevalence of odontogenic cysts was similar to that reported in the literature, with inflammatory cysts occurring most frequently.

    Full Text Available Experienced laparoscopic surgeons should consider laparoscopy as an alternative to laparotomy in management of ovarian dermoid cysts in selected cases. The aim of this study was to analyze the safety of laparoscopy in ovarian dermoid cysts treatment and risk of chemical peritonitis. We report 63 cases of patients (mean age of 37 with ovarian dermoid cysts originating from the ovary, treated from 2002 to 2010. Most of the patients underwent cysts removal. In 7 patients salpingo-oophorectomy was performed. We used 15 mm trocars for removing specimens. In patients with dermoid cyst rupture peritoneal cavity was washed out thoroughly with Ringer lactate and drained for 24-48 hours. All the material extracted was sent for a histopathology examination. The diagnosis of mature ovarian dermoid cysts was confirmed in 58 (92.63% of cases and immature ovarian dermoid cysts in 5 (7.37% cases. Dermoid cysts were composed of tissue developed from three germinative layers in 31 (49% patients, from two germinative layers in 25 (40%, and in 7 (11% patients from one germinative layer. No intra or postoperative complications occurred. No signs or symptoms of chemical peritonitis were observed regardless of cystic spillage or not. We conclude that the risk of chemical peritonitis can be minimized when undertaking laparoscopic removal of ovarian dermoid cysts if the peritoneal cavity is washed out thoroughly from spillage of cyst contents. Drainage of peritoneal cavity should be performed in the patients with the ruptured dermoid cysts.

    Extracellular matrix metalloproteinase inducer (EMMPRIN) is known to induce matrix metalloproteinase (MMP) production. The expression of EMMPRIN in odontogenic cysts has not been previously studied. This study was done to determine the presence and the variability of EMMPRIN expression in various types of odontogenic cysts. An immunohistochemical study using a polyclonal anti-EMMPRIN antibody was done using 48 odontogenic cyst cases: 13 odontogenic keratocysts (OKCs), 18 dentigerous cysts (DCs), and 17 periapical cysts (PAs). Twelve cases of normal dental follicles (DFs) were also included in this study for comparison. EMMPRIN immunoreactivity was detected in all of the cysts and DFs studied. In odontogenic cysts, EMMPRIN immunoreactivity was generally higher in basal cells than in suprabasal cells. The overall EMMPRIN expression in the epithelial lining of the 3 different types of odontogenic cyst was significantly higher than in the DFs. Overall EMMPRIN expression was also found to be significantly higher in the epithelial lining of OKCs than in the other types of cysts. This study confirmed that EMMPRIN is present in odontogenic cysts and DFs. The higher EMMPRIN expression in OKCs suggests that it may be involved in the aggressive behavior of this type of cyst.

    Full Text Available Background: Echinococcosis is a parasitic disease with worldwide distribution which is caused by the tapeworms Echinococcus granulosus. Diagnosis of the disease relies on imaging techniques, but the techniques are not able to differentiate the cyst from benign or malignant tumors; hence, appropriate serologic methods are required for the differential diagnosis of the infection. Materials and Methods: In this investigation, different sheep hydatid cyst antigens probed with thirty sera of patients with hydatid cyst and also thirty human normal sera using Western immunoblotting technique. Considering results of surgery as gold standard, sensitivity and specificity of Western blotting was estimated. Results: Sera of 29, 26, and 16 patients with hydatid cyst reacted with specific bands of hydatid cyst fluid (HCF, protoscolex crude antigen, and cyst wall crude antigen, respectively. However, none of the normal human sera reacted with those specific bands. Conclusion: A 20 kDa band of sheep HCF is an appropriate antigen for serodiagnosis of hydatid cyst infection.

    Full Text Available ABSTRACT Dermoids are congenital lesions representing normal tissue in abnormal location. Orbital dermoid cysts are divided into superficial and deep dermoids. Depending on type and location, superficial ocular dermoid cysts are divided into limbal, dermoid cyst and epibulbar dermoid cyst or dermolipoma. The most common location for the epibulbar dermoid cyst is inferotemporal region of eye. They are usually asymptomatic or may present with inflammatory response due to leakage of cyst contents or may cause local irritation due to protruding hair and do cause cosmetic blemish to a school going child. For local irritation and cosmetic reasons, complete surgical excision with intact capsule of epibulbar dermoid cyst is mandatory to prevent acute inflammatory response and its recurrence. In this article we are presenting the clinical features and surgical management of an inferotemporal epibulbar dermoid in a male patient.

    Acute bleeding within a colloid cyst of the third ventricle represents a rare event causing sudden increase in the cyst volume that may lead to acute hydrocephalus and rapid neurological deterioration. We report a case of spontaneous rupture of haemorrhagic third ventricular colloid cyst and its management. A 77-year-old ex-smoker presented with unsteady gait, incontinence and gradually worsening confusion over a 3-week period. Brain CT scan findings were highly suggestive of a third ventricular colloid cyst with intraventricular rupture. He underwent cyst excision and histopathology, which confirmed the radiological diagnosis with evidence of haemorrhage within the cyst. A ventriculo peritoneal shunt was performed for delayed hydrocephalus. Surgical management of these patients must include emergency ventriculostomy followed by prompt surgical removal of the haemorrhagic cyst.

    We report a cervical intraspinal cyst in a dog that was initially tetraparetic but spontaneously recovered completely. MRI revealed a well-demarcated intraspinal cyst located dorsally to a degenerated intervertebral disc. The location of the cyst and its signal features on MRI resembled those of discal cysts previously reported in humans. It has been reported in dogs that clinical signs of a intraspinal cyst are similar to those of intervertebral disc herniation and both conditions require surgical intervention. Unexpectedly, our case showed rapid spontaneous recovery and the follow-up MRI revealed complete resolution of the intraspinal cyst and spinal cord compression. Spontaneous recovery of degenerative intraspinal cyst may occur in dogs, similar to rare human cases as reported previously. (author)

    Systematic surveys with advanced non-invasive imaging techniques have revealed that hepatic cysts are quite common in the general population. Therefore, we retrospectively examined our case series and compared it with the literature. Between January 1990 and December 2000, 228 patients with non-parasitic liver cysts were referred to the outpatients section of the Department of Surgery of the University of Cagliari and 23 were submitted to treatment: 14 patients (60.8%) for solitary cyst and 9 (39.2%) for multiple simple cysts of the liver. One patient (4.5%) had right upper quadrant pain. Eleven (47.8%) patients were asymptomatic: 7 (63.7%) required treatment for other pathologies, 3 (27.3%) for a progressive enlargement of the cyst and 1 (9%) for a suspected hydatid disease. Mean diameter of the treated cysts measured by preoperative CT or US was 8.8 cm (range 7-14). Percutaneous aspiration-injection reaspiration (PAIR) was performed in 5 patients (21.7%), US-guided in 2 cases (40%) and CT-guided in 3 (60%). Twenty patients (86.9%) underwent cysts unroofing, 18 (78.2%) with open surgical fenestration and the latest 2 cases with a laparoscopic approach. Two patients had PAIR as second treatment for recurrence: CT-guided in one and US-guided in the other case. Four (25%) out of 16 patients treated exclusively for cystic liver disease, had fever in 3 cases and nausea and vomiting in 1 case; 8 patients (50%) had an intraperitoneal drainage for a mean of 6-7 days (range 4-11) and of 116 cc of serum-hematic liquid. In our opinion the choice of an adequate treatment must be based on an accurate evaluation of the clinical aspects of the patients and on the characteristics of cystic lesions such as number, size and location. These data let us to choose a surgical treatment rather than a strict US follow-up and to get the best outcome in terms of absence of recurrence, and less biological and economic costs.

  12. Apical Cyst Theory: a Missing Link.

    Science.gov (United States)

    Huang, George T-J

    2010-10-05

    The mechanism of the formation of apical cyst has been elusive. Several theories have long been proposed and discussed speculating how an apical cyst is developed and formed in the jaw bone resulting from endododontic infection. Two popular theories are the nutritional deficiency theory and the abscess theory. The nutritional deficiency theory assumes that the over proliferated epithelial cells will form a ball mass such that the cells in the center of the mass will be deprived of nutrition. The abscess theory postulates that when an abscess cavity is formed in connective tissue, epithelial cells proliferate and line the preexisting cavity because of their inherent tendency to cover exposed connective tissue surfaces. Based on the nature of epithelial cells and the epithelium, nutritional theory is a fairy tale, while abscess theory at best just indicates that abscess may be one of the factors that allows the stratified epithelium to form but not to explain a mechanism that makes the cyst to form. Apical cyst formation is the result of proliferation of resting epithelial cells, due to inflammation, to a sufficient number such that they are able to form a polarized and stratified epithelial lining against dead tissues or foreign materials. These stratified epithelial lining expands along the dead tissue or foreign materials and eventually wrap around them as a spherical sac, i.e. a cyst. The space in the sac is considered the external environment separating the internal (tissue) environment - the natural function of epithelium. This theory may be tested by introducing a biodegradable device able to slowly release epithelial cell mitogens in an in vivo environment implanted with epithelial cells next to a foreign object. This will allow the cells to continuously proliferate which may form a cystic sac wrapping around the foreign object.

    Pineal cysts, both simple and complex, are commonly encountered in children. More cysts are being detected with MR technology; however, nearly all pineal cysts are benign and require no follow-up. To discover the prevalence of pineal cysts in children at our institution who have undergone high-resolution 3-T MRI. We retrospectively reviewed 100 consecutive 3-T brain MRIs in children ages 1 month to 17 years (mean 6.8 ± 5.1 years). We evaluated 3-D volumetric T1-W imaging, axial T2-W imaging, axial T2-W FLAIR (fluid attenuated inversion recovery) and coronal STIR (short tau inversion recovery) sequences. Pineal parenchymal and cyst volumes were measured in three planes. Cysts were analyzed for the presence and degree of complexity. Pineal cysts were present in 57% of children, with a mean maximum linear dimension of 4.2 mm (range 1.5-16 mm). Of these cysts, 24.6% showed thin septations or fluid levels reflecting complexity. None of the cysts demonstrated complete T2/FLAIR signal suppression. No cyst wall thickening or nodularity was present. There was no significant difference between the ages of children with and without cysts. Cysts were more commonly encountered in girls than boys (67% vs. 52%; P = 0.043). There was a slight trend toward increasing pineal gland volume with age. Pineal cysts are often present in children and can be incidentally detected by 3-T MRI. Characteristic-appearing pineal cysts in children are benign, incidental findings, for which follow-up is not required if there are no referable symptoms or excessive size. (orig.)

    An odontogenic keratocyst (OKC) is a developmental odontogenic cyst with aggressive clinical behavior. This cyst shows a different growth mechanism from the more common dentigerous cyst and now has been renamed as a keratocystic odontogenic tumor (KCOT). Inflammation can assist tumor growth via different mechanisms including dysregulation of the p53 gene. This study aims to assess and compare the expression of tumor suppressor gene p53 in inflamed and non-inflamed types of OKC and dentigerous cyst. Immunohistochemical expression of p53 was assessed in 14 cases of dental follicle, 34 cases of OKC (including 18 inflamed OKCs), and 31 cases of dentigerous cyst (including 16 inflamed cysts). The mean percentage of p53 positive cells was 0.7% in dental follicles, 5.4% in non-inflamed OKCs, 17.3% in inflamed OKCs, 1.2% in non-inflamed dentigerous cysts, and 2.2% in inflamed dentigerous cysts. The differences between the groups were statistically significant ( p < 0.050) except for the difference between inflamed and non-inflamed dentigerous cysts, and between dental follicle and non-inflamed dentigerous cyst. The difference in p53 expression in OKC and dentigerous cyst can explain their different growth mechanism and clinical behavior. Inflammation is responsible for the change in behavior of neoplastic epithelium of OKC via p53 overexpression.

    Two cases of hypopharyngeal cyst are reported. Both cysts occurred in the piriform sinus of the hypopharynx. Histopathological examination indicated that both were retention cysts. These cysts were removed by laryngomicrosurgical technique using a side-opened direct laryngoscope. In the cyst with a distinct base, a laryngomicrosurgical snare was used for removal. In the wide-based cyst, the mucous membrane around the cyst was incised with an electrosurgical instrument and then detached to facilitate removal. In this paper, we describe our surgical procedure for removing hypopharyngeal cysts and discuss the causes of such cysts.

    Background and aims. Odontogenic cysts and tumors have a wide spectrum of clinical characteristics that lead to the different management strategies. Since definite diagnosis is difficult in some cases, it has been suggested that CD56 may be a candidate marker for definitive diagnosis of some odontogenic tumors. The present study was designed to examine CD56 expression in lesions with histopathological similarities. Materials and methods. In this cross-sectional, analytical study the subjects were 22 ameloblastomas, 13 dentigerous cysts, 10 keratocystic odontogenic tumors (KCOT), 4 adenomatoid odontogenic tumors (AOT), 3 orthokeratinized odonto-genic cysts, 3 calcifying odontogenic cysts (COC) and one glandular odontogenic cyst (GOC). All the samples were examined for CD56 immunoreactivity. Data were analyzed using chi-square test. Results. Twenty cases (91%) of ameloblastomas, 3 (75%) AOT, 4 (40%) KCOT and one case of GOC were positive for CD56. None of the dentigerous cysts, COC and orthokeratinized odontogenic cysts was CD56-positive. There was a significant difference in the CD56 expression between ameloblastoma and dentigerous cyst, as well as COC. Also, KCOT showed significantly higher expression than orthokeratinized odontogenic cyst. Conclusion. In this study CD56 expression was limited to the odontogenic tumors and more aggressive cystic lesions. This marker can be a useful aid for distinguishing cysts and tumors from similar lesions.

    Heterodera is a genus of cyst-forming nematodes, including the cereal cysts which can provoke yield reductions in grain crops. As little is known about the occurrence of these cysts in Belgian grain fields, a survey was organized, starting in Flanders. Soil samples were taken from 50 fields where cereals are grown in rotation with mainly beet, potato and vegetables. Cysts were extracted from the 112 samples and 10 individuals per sample were identified up to species level by morphometrical and morphological observations. The beet cyst nematode, Heterodera schachtii, was found in 34 fields (56%) at infestation levels varying from 0.6 to 1322 cysts/kg soil. Other Heterodera species (e.g. H. trifolii, H. mani) were found in low numbers and sometimes in mixtures with H. schachtii, but no cereal cysts were detected. This survey confirms that beet cyst nematodes are a problem in Flanders. The few cereal cysts that might be present were perhaps not detected due to the few individuals that were identified. For this reason, molecular identification tools which allow fast and accurate identification of Heterodera species would be very useful. It could be interesting to find out why cereal cysts are suppressed in our regions and to expand the survey to the Walloon region where more cereals are grown.

    A radicular cyst is one of the furthermost everyday odontogenic cysts of the anterior maxilla, not regularly comprehended in youth. They are found mostly at the apices of the tooth (periapical cyst), lateral surface of the roots (lateral radicular cyst) and remains in the jaw after removal of the offending tooth (residual cyst). The radicular cyst has been catalogued as an inflammatory cyst, as an outcome to pulpal necrosis succeeding caries, with a linked periapical inflammatory reaction. They advance sluggishly and asymptomatic lest infected. Because of this they can extent to big dimensions. Many times it is perplexing to segregate radicular cysts from the obligatory pre-existing chronic periapical periodontitis lesions radiographically. Here, we present a rare case with bilateral radicular cyst in relation to first molar of the mandible in a 19-year-old. Orthopantomograph showed a large unilocular radiolucency with a well-defined border in the periapical region of the first molar on the left side extending from the root of the second premolar to the mesial root of the second molar. Correspondingly another well-defined unilocular radiolucency with a well-defined border was seen on the right side of the mandible. Several treatment possibilities are presented for a radicular cyst such as surgical endodontic treatment, extraction of the transgressing tooth, enucleation with primary closure, and marsupialization trailed by enucleation. The patient management comprised surgical enucleation of cystic sac followed by rehabilitation of the same area.

    There is a variety of treatment modalities for unicameral bone cysts, with variable outcomes reported in the literature. Although good initial outcomes have been reported, the success rate has often changed with longer-term follow-up. We introduce a novel, minimally invasive treatment method and compare its clinical outcomes with those of other methods of treatment of this lesion. From February 1994 to April 2008, forty patients with a unicameral bone cyst were treated with one of four techniques: serial percutaneous steroid and autogenous bone-marrow injection (Group 1, nine patients); open curettage and grafting with a calcium sulfate bone substitute either without instrumentation (Group 2, twelve patients) or with internal instrumentation (Group 3, seven patients); or minimally invasive curettage, ethanol cauterization, disruption of the cystic boundary, insertion of a synthetic calcium sulfate bone-graft substitute, and placement of a cannulated screw to provide drainage (Group 4, twelve patients). Success was defined as radiographic evidence of a healed cyst or of a healed cyst with some defect according to the modified Neer classification, and failure was defined as a persistent or recurrent cyst that needed additional treatment. Patients who sustained a fracture during treatment were also considered to have had a failure. The outcome parameters included the radiographically determined healing rate, the time to solid union, and the total number of procedures needed. The follow-up time ranged from eighteen to eighty-four months. Group-4 patients had the highest radiographically determined healing rate. Healing was seen in eleven of the twelve patients in that group compared with three of the nine in Group 1, eight of the twelve in Group 2, and six of the seven in Group 3. Group-4 patients also had the shortest mean time to union: 3.7 ± 2.3 months compared with 23.4 ± 14.9, 12.2 ± 8.5, and 6.6 ± 4.3 months in Groups 1, 2, and 3, respectively. This new

    To investigate the incidence and prevalence of developmental odontogenic cysts in children and adolescents and compare the features of the two most common types, dentigerous cyst and keratocystic odontogenic tumor (KCOT). A retrospective review in a series of 369 patients with all histological diagnoses of developmental odontogenic cysts in children (≤12 years) and adolescents (13-18 years) was conducted. Among these, 361 (97.8%) patients were diagnosed as dentigerous cyst (n = 281) and KCOT (n = 80), with the male-to-female ratios of dentigerous cyst and KCOT both being 2:1. The average age of the patients with KCOT was older than that of those with dentigerous cyst (14.7 years vs 11.8 years, p < 0.001). Dentigerous cyst (59.1%) was more common in children, but KCOT (78.8%) was more common in adolescents (p < 0.001). Dentigerous cyst (57.6%) predominantly located on the maxilla, but KCOT (60.3%) predominantly located on the mandible (p = 0.010). Adolescent patients with lesions located on the mandible would favor KCOT over dentigerous cyst. This study aids in better knowledge of the prevalence of developmental odontogenic cysts in a large pediatric population, and shows that a well-supported early diagnosis is indispensable for a more adequate treatment.

    Glandular odontogenic cysts (GOCs) are rare intrabony solitary or multiloculated cysts of odontogenic origin. The importance of GOCs lies in the fact that they exhibit a propensity for recurrence similar to keratocystic odontogenic tumors and that they may be confused microscopically with central mucoepidermoid carcinoma. Thus, the oral and maxillofacial radiologists play an important role in definitive diagnosis of GOC based on distinctive cases; though they are rare. In large part, this is due to the GOC's complex and frequently non-specific histopathology. This report describes a case of GOC occurrence in the posterior mandibular ramus region in a 17-year-old female, which is a rare combination of site, age, and gender for occurrence.

    Full Text Available "Hydatid" is a Greek word which means "a drop of water." Hydatid cysts occur in hydatid disease or echinococcosis, which is one of the most geographically prevalent zoonosis. This zoonotic infection in humans is mainly caused by infection by the larval stage of the dog tapeworm Echinococcus granulosus. This tapeworm infestation is widespread in sheep, goats, cattle, and dogs. This chronic disease is present worldwide among herding populations who live in close proximity to dogs and herd animals. It is a serious and potentially fatal condition and symptoms may occur a long time after the early infection. The most frequently affected organs are liver, lungs, followed by bones and brain, and extremely unusual occurrence has been found in the oral cavity, which was noticed in the present case. So hereby, we reveal a very rare case of intraoral hydatid cyst in a 20-year-old female patient.

    Aneurysmal bone cysts (ABCs) are expansile, lytic, bone lesions consisting of multiple fibrous, thin-walled, blood-filled cavities. Although the origin of these cysts is uncertain, alteration in local hemodynamics related to venous obstruction or arteriovenous fistulas is thought to be an inciting factor. Most patients are less than 30 years of age and present with symptoms secondary to compression of adjacent structures or pathologic fracture. Subperiosteal ABCs are atypical and constituted only 16 (7%) of the 238 cases presented by Vergel De Dios et al. Campanacci et al also classified 9 (5%) of 198 cases as subperiosteal. Our purpose is to review the literature concerning the radiologic findings of subperiosteal ABCs and discuss the radiographic, computed tomographic (CT) and magnetic resonance imaging (MRI) findings of 2 histologically proven cases.

    Both symptomatic Rathke's cleft cyst and intrasellar abscess are exceedingly rare. We present a case of intrasellar abscess developed in a Rathke's cleft cyst. A 60-year-old man was admitted to our hospital with complaints of polyuria, polydipsia, headache, and remittent fever. On admission, his neurological and ophthalmological examination was normal. Panhypopituitarism was revealed by endocrine testing. Plain-skull X-ray films showed no abnormalities, but a CT scan showed a small cystic lesion with a ring-like enhancement in the sella turcica and paranasal sinusitis. Further sagittal reconstruction of the CT scan demonstrated that the diaphragma sellae protruded upwards and that the pituitary stalk was markedly enhanced and enlarged. After the sinusitis improved, transsphenoidal surgery was carried out. Approximately 1 ml of the purulent contents were aspirated from the intrasellar region. The postoperative course was uneventful. A histological examination of the abscess wall revealed a ciliated columnar epithelium and inflammatory-cell infiltration beneath the epithelium. (author)

    The computed tomography (CT) findings in six cases of Rathke's cleft cyst (RCC) were presented. According to the location of the RCC, we divided these cases into two types - the suprasellar type and the intrasellar type. The characteristic CT findings are as follows: SUPRASELLAR type 1. smooth, round mass, 2. various densities, 3. no enhancement, INTRASELLAR type 1. low-density area in the posterior sella turcica, 2. no enhancement, 3. suprasellar high-density mass; enhanced pituitary gland pushed up by the intrasellar RCC. As RCC are more common than was formerly suspected, this disease should always be considered in the differential diagnosis of a patient showing a non-enhancing, non-calcified sellar/suprasellar cyst on CT scans.

    We report 11 cases of vermian partial agenesis without posterior fossa cyst or hemispheric abnormalities. Characteristic MR signs were: absence of the posterior lobe, hypoplasia of the anterior lobe, a narrow sagittal cleft separating the hemispheres (''buttocks sign'') and fourth ventricle deformity. The main clinical signs were complex oculomotor dysfunction and developmental delay. None of the patients had respiratory symptoms. Consideration is given to the relationship between Joubert syndrome and this entity as well as to embroyological data. (orig.)

    Splenic cysts are relatively uncommon, and are usually asymptomatic. They are benign, typically treated conservatively and followed up with ultrasound examination, with few reported complications. We report a case of a simple splenic cyst that was followed up on imaging over a seven-year period. During that time, the cyst gradually enlarged from 5 cm to 12 cm in diameter, however the patient remained asymptomatic. After seven years, the patient was admitted with abdominal pain and a pelvic mass. The spleen was located within the pelvis, which was felt to be due to the weight of the cyst which caused the spleen to migrate out of its normal position. This case illustrates an extremely unusual complication, and suggests that while most splenic cysts may be managed conservatively, enlarging cysts may be prone to gravitational effects and prophylactic treatment should be considered.

    A retrospective analysis of oral cysts that were seen over an 11-year period in children at a dental institution in Nigeria was carried out. In general, oral cysts accounted for only 2.6% of the total biopsied lesions during the period under review. The most common oral cysts were the mucous retention cysts, the gingival cysts of infants and the dentigerous cyst. The commonest sites were the maxilla, the mandible and the floor of the mouth respectively and there was no significant difference in sex preference. Most of the cases were seen in the age group 11-16 years while the least was in the group aged 6-10 years.

    The aim of this study is to evaluate the caveolin-1 expression in a group of odontogenic cysts and tumors. In this cross-sectional study, the expression of caveolin-1 was evaluated immunohistochemically in 75 samples including 18 cases of dentigerous cyst, 18 odontogenic keratocysts, 3 orthokeratinized odontogenic cysts, 2 calcifying odontogenic cysts and 34 ameloblastomas (solid and unicystic). Positive immunohistochemical reaction was found in 100% of odontogenic cysts and this was significantly more than both unicystic (65%) and solid (55%) ameloblastomas. The present study showed the expression of caveolin-1 in all odontogenic cysts and more than ameloblastomas. The results suggested that absence of caveolin-1 might enhance aggressiveness of odontogenic lesions and could be a useful marker for distinguishing ameloblastomas from other odontogenic lesions.

    Odontogenic maxillary cysts and tumours originate from the tooth root and have traditionally been treated through an intraoral approach. Here, we report the efficacy and utility of endoscopic modified medial maxillectomy (EMMM) for the treatment of odontogenic maxillary cysts and a tumour. We undertook EMMM under general anaesthesia in six patients: four had radicular cysts, one had a dentigerous cyst, and one had a keratocystic odontogenic tumour. The cysts and tumours were completely excised and the inferior turbinate and nasolacrimal duct were preserved in all patients. There were no peri- or postoperative complications, and no incidences of recurrence. Endoscopic modified medial maxillectomy appears to be an effective and safe technique for treating odontogenic cysts and tumours.

    We present two cases of multiple jaw cysts not associated with basal cell nevus syndrome. Case 1 : a nine year-old boy visited CNU Hospital for orthodontic treatment and his radiographs showed cystic lesions surrounding the crowns of teeth 13 and 17 respectively, which were diagnosed as dentigerous cysts. Subsequently, two more cysts were found on his follow-up radiographs in 12 and 15 months. The two cysts were determined to be odontogenic keratocysts. The boy had no skeletal abnormalities and no skin lesions associated with basal cell nevus syndrome. Case 2: a fifty-eight year old man had three impacted third molars with pericoronal radiolucencies, which were diagnosed as dentigerous cysts. He had no additional abnormalities associated with basal cell nevus syndrome. Multiple jaw cysts can occur at any age, and periodic radiographic surveillance may be needed for any cases of impacted tooth.

    Case report. We report a rare case that a ganglion cyst compressed the sciatic nerve and caused sciatica and claudication in a 51-year-old male. Sciatica and claudication commonly occurs in spinal stenosis. To our knowledge, only 4 cases have been reported on sciatica resulting from posterior ganglion cyst of hip. A 51-year-old male had a 2-month history of radiating pain on his right leg. He could only walk 20 to 30 m before stopping and standing to rest for 1 to 3 minutes. Interestingly, he was able to walk longer distances (about 200 m) when walking slowly in small steps, without any rest. He had been treated as a case of lumbar disc herniation, but conservative treatment was ineffective. On buttock examination, a round, hard, and fixative mass was palpated at the exit of the sciatic nerve. MR imaging of hip revealed a multilocular cystic mass located on the posterior aspect of the superior gemellus and obturator internus, compressing the sciatic nerve. On operation, we found that the cyst extended to the superior gemellus and the obturator internus, positioned right at the outlet of the sciatic nerve. At 18 months of follow-up, the patient continued to be symptom free. He returned to comprehensive physical activity with no limitations. For an extraspinal source, a direct compression on the sciatic nerve also resulted in sciatica and claudication. A meticulous physical examination is very important for the differential diagnosis of extraspinal sciatica from spinal sciatica.

    A case of a ruptured dermoid cyst presenting headaches and dizziness as the only symptoms is presented. A 60-year-old woman was admitted to our hospital after complaining of headaches for 5 years and of dizziness for 1 week. The results of physical and neurological examinations were normal. An X-ray of the skull revealed an intracranial calcification in the left frontal region. CT disclosed calcification and a large low-density area in the left parasellar region and the frontal lobe. The mass consisted of two different areas of density. There were multiple, isolated, low-density spots in the left Sylvian fissure and the interpeduncular cistern. No abnormal enhancement was seen by CECT. Angiograms showed an elevation of the A 1 portion of ACA and a lateral shift of MCA. A left fronto-temporal craniotomy was performed. Chronic or past leptomeningitis was suspected because of the arachnoid-membrane thickening. Multiple fatty globules were present in the left Sylvian fissure. A large, soft, fatty tumor was completely removed. The histologic diagnosis was a dermoid cyst. After this operation, the headaches and dizziness were reduced. It is unclear whether the headaches were caused by the compression of the tumor or by the meningeal irritation of the fatty debris. According to the findings on the arachnoid membrane, however, it seems likely that fatty debris detached from the tumor spilled out intermittently from the cyst into the subarachnoid space, resulting in meningeal irritation.

    Purpose: This paper presents a modification of the known method for percutaneous treatment of hydatid cyst, the PAIR technique. It aimed to achieve safe aspiration of large symptomatic cysts and cysts with a danger of impending rupture. Methods: We designed a coaxial catheter system to achieve concomitant evacuation of cyst contents while infusing scolicidal agent. Hypertonic saline is used to wash out cyst contents and to kill protoscolices. This was followed by injection of a sclerosant (ethyl alcohol 95%) into the residual cyst cavity to prevent formation of a cyst collection after the procedure. Seventeen cysts in 14 patients were successfully aspirated. Follow-up plain radiographs, ultrasonography and CT were performed weekly in the first 4 weeks and then at 3, 6 and 12 months for all patients. Seven patients (9 drained cysts) were followed up for 2 years and 1 patient for 3 years. Results: All cysts were successfully aspirated. The following morphologic changes were noticed: a gradual decrease in cyst size (17 cysts, 100%), thickening and irregularity of the cyst wall due to separation of endocyst from pericyst (7 cysts, 41%), development of a heterogeneous appearance of the cyst components (8 cysts, 47%) and development of pseudotumor (2 cysts, 12%). None of the treated cysts disappeared completely. No significant procedure-related complications were encountered. Conclusion: This modified PAIR technique is a reliable method for percutaneous treatment of risky and symptomatic hydatid cysts.

    Endodontic diagnosis is challenging and depends on the organisation of information from the patient history, clinical examination and analysis of the pulp, radiographic and histopathological assessment. A 35-year-old man was endodontically treated for radiolucency in relation to the roots of maxillary central incisors as it was a provisionally diagnosed case of radicular cyst. Since the palatal swelling persisted, the lesion was re-evaluated using relevant diagnostic aids and a diagnosis of nasopalatine duct cyst (NPDC) was made, which was missed during the initial assessment. An erroneous interpretation of cystic radiolucency in relation to maxillary central incisors can often lead to inappropriate treatment planning. This case highlights the relevant aspects in the diagnosis of NPDC when it is mistaken for a radicular cyst and emphasises the need for thorough clinical examination and relevant investigations for periapical radiolucencies of questionable origin before initiating endodontic therapy.

    Full Text Available Primary hydatid cyst in the pelvis is rare, and usually presents with pressure symptoms affecting the adjacent abdominal organs. We describe a rare hydatid cyst which was eroding the sacral hallow, protruding into the right sciatic foramen and presenting as a radiating pain and weakness of right lower limb due to compression of the lumbosacral nerve roots. Laparotomy with removal of cyst and postoperative treatment with albendazole is effective in controlling the disease and preventing recurrence.

    Full Text Available Abstract Background The splenic cysts constitute a very rare clinical entity. They may occur secondary to trauma or even being more seldom due to parasitic infestations, mainly caused by ecchinocccus granulosus. Literature lacks a defined concencus including the treatment plans and follow up strategies, nor long term results of the patients. In the current study, we aimed to evaluate the diagnosis, management of patients with parasitic and non-parasitic splenic cysts together with their long term follow up progresses. Methods Twenty-four patients with splenic cysts have undergone surgery in our department over the last 9 years. Data from eighteen of the twenty-four patients were collected prospectively, while data from six were retrospectively collected. All patients were assessed in terms of age, gender, hospital stay, preoperative diagnosis, additional disease, serology, ultrasonography, computed tomography (CT, cyst recurrences and treatment. Results In this study, the majority of patients presented with abdominal discomfort and palpable swelling in the left hypochondrium. All patients were operated on electively. The patients included 14 female and 10 male patients, with a mean age of 44.77 years (range 20–62. Splenic hydatid cysts were present in 16 patients, one of whom also had liver hydatid cysts (6.25%. Four other patients were operated on for a simple cyst (16% two patients for an epithelial cyst, and the last two for splenic lymphangioma. Of the 16 patients diagnosed as having splenic hydatit cysts, 11 (68.7% were correctly diagnosed. Only two of these patients were administered benzimidazole therapy pre-operatively because of the risk of multicystic disease The mean follow-up period was 64 months (6–108. There were no recurrences of splenic cysts. Conclusion Surgeons should keep in mind the possibility of a parasitic cyst when no definitive alternative diagnosis can be made. In the treatment of splenic hydatidosis, benzimidazole

    Bronchogenic cysts are usually discovered only incidentally in the adult. A giant bronchogenic cyst in a 19-year-old woman presenting with pain and shortness of breath was mistaken for tension pneumothorax and initially treated with tube thoracostomy. Giant bullae were diagnosed by computed tomography. Bullae resection was undertaken, but the remaining lung tissue required pneumonectomy. Pathologic examination of the specimen confirmed bronchogenic cyst.

    Scrotum's sebaceous cyst is an usual pathology, not life threatening, but susceptible of infection, producing abscess with their associated cosmetic and psychological disturbance. The classical management is the complete excision, under local anaesthesia, to prevent its recidive. Until today, the use of de Nd-YAG laser for the management of the scrotum's sebaceous cysts as not been reported. We report a case of a young man with several scrotum's sebaceous cysts, treated successfully with the use of a Nd-YAG laser.

    2017-07-01

    We systematically evaluated the Bosniak classification system with malignancy rates of each Bosniak category, and assessed the effectiveness related to surgical treatment and oncologic outcome based on recurrence and/or metastasis. In a systematic review according to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) statement and the QUADAS-2 (Quality Assessment of Diagnostic Accuracy Studies) criteria, we selected 39 publications for inclusion in this analysis and categorized them into 1) surgical cohorts-all cysts treated surgically and 2) radiological cohorts-cysts with surgical treatment or radiological followup. A total of 3,036 complex renal cysts were categorized into Bosniak II, IIF, III and IV. In surgical and radiological cohorts pooled estimates showed a malignancy prevalence of 0.51 (0.44, 0.58) in Bosniak III and 0.89 (0.83, 0.92) in Bosniak IV cysts, respectively. Stable Bosniak IIF cysts showed a malignancy rate of less than 1% during radiological followup (surveillance). Bosniak IIF cysts, which showed reclassification to the Bosniak III/IV category during radiological followup (12%), showed malignancy in 85%, comparable to Bosniak IV cysts. The estimated surgical number needed to treat to avoid metastatic disease of Bosniak III and IV cysts was 140 and 40, respectively. The effectiveness of the Bosniak classification system for complex renal cysts was high in categories II, IIF and IV, but low in category III, and 49% of Bosniak III cysts was overtreated because of a benign outcome. This surgical overtreatment combined with the excellent outcome for Bosniak III cysts may suggest that surveillance is a rational alternative to surgery. This will require further study to assess whether surveillance of Bosniak III cysts will prove safe. Copyright © 2017 American Urological Association Education and Research, Inc.

  1. Role of tumour necrosis factor in pathogenesis of radicular cyst

    International Nuclear Information System (INIS)

    Qureshi, W.U.R.; Idris, M.; Khan, S.A.

    2011-01-01

    Background: The radicular cyst is very common odontogenic cyst of the jaws, which is usually associated with a tooth with necrotic pulp. The cyst formation requires proliferation of the epithelial rest cells of Malassez present in the periodontal ligament. Proliferation of epithelial rest cells of Malassez is an essential event in the Pathogenesis of radicular cyst. The wall of the cyst contains epithelial cells, macrophages, fibroblasts and other cells. TNF is one of inflammatory mediators, which is produced by macrophages and monocytes. This study was carried out to investigate the role of tumour necrosis factor in the pathogenesis of radicular cyst, which is by far the commonest cystic lesion of the jaws. Methods: Explants from 20 radicular cysts were cultured in vitro to grow the epithelial cells. However, the cultures were rapidly contaminated with fibroblasts and it was impossible to grow the epithelial cells separately. Therefore, the proliferative effect of Tumour Necrosis Factor (TNF) was studied on mammalian epithelial cells. Results: TNF at low concentration had a proliferative effect on the epithelial cells, which may play some role in pathogenesis of radicular cyst. Conclusion: TNF stimulated the epithelial cell proliferation in low concentration and inhibit the proliferation in higher concentrations. These two effects may have some implications in the pathogenesis of radicular cyst. (author)

    Full Text Available Cardiac hydatid cyst is rare and usually occurs in the setting of disseminated disease. Herein, we reported a case of isolated right atrial hydatid cyst misdiagnosed clinically as a tumor. A 65-year-old woman diagnosed as having large right atrial mass suspected of malignancy underwent resection of the cardiac mass. Histopathological examination showed laminated membrane and protoscolices of Echinococcus Granulosus. However, all other work-ups failed to document systemic diseases. Therefore, isolated cardiac hydatid cyst was diagnosed. Hydatid cysts should be considered in differential diagnosis of any cardiac mass, especially in endemic areas.

    Six patients with acquired spinal subarachnoid cysts secondary to epidural anesthesia were evaluated with MR imaging (seven patients) and intraoperative US (three patients). The cysts were located in the lower cervical and thoracic spine. Adhesions and irregularity of the cord surface were frequently noted. Associated intramedullary lesions, including intramedullary cysts and myelomalacia, were seen in two of the patients. Arachnoiditis was unsuspected clinically in three patients, and MR imaging proved to be the diagnostic examination that first suggested the cause of the patients symptoms. The underlying mechanism for the formation of these cysts is a chemically induced arachnoiditis

    Full Text Available Theca lutein cysts can occur in 20-25% of molar pregnancies. These cysts can undergo complications such as torsion, rupture, and haemorrhage. As these are functional cysts, when there are complications such as torsion they can be managed conservatively by aspirating the cysts under ultrasound guidance or by detorsion at the time of laparoscopy. By simple detorsion, ovaries can be preserved in 80-90% of cases. In order to prevent recurrence adnexal fixation can be undertaken by plicating the ovarian ligament.

    Present day knowledge in laryngology maintains that the free edge of the true cord mucosa is devoid of glands so that retention cysts should not occur in this tissue. When such cysts do occur, it is difficult to define their pathogenesis. Reference is made to the author's earlier study which found a regular occurrence of mucous glands in the squamous epithelial region of the vocal cords. A retention cyst in the true cord is described histologically in the present report. The glands responsible for these cysts are believed to function by moistening the mucous membrane of the vocal cords.

    While mucoceles of the oral mucosa are relatively common, multiple mucous retention cysts have not previously been reported. In this article two such cases, in which numerous minor salivary gland ducts had dilated to the point of cyst formation, are described. The number of individual cysts exceeded 100 in each case. Since it is clear that these cysts formed as a result of dilatation of salivary ducts, it would seem that either the ducts were blocked by altered secretion or there was an acquired or congenital weakness in their structure.

  7. Automated classification of four types of developmental odontogenic cysts.

    2014-04-01

    Odontogenic cysts originate from remnants of the tooth forming epithelium in the jaws and gingiva. There are various kinds of such cysts with different biological behaviours that carry different patient risks and require different treatment plans. Types of odontogenic cysts can be distinguished by the properties of their epithelial layers in H&E stained samples. Herein we detail a set of image features for automatically distinguishing between four types of odontogenic cyst in digital micrographs and evaluate their effectiveness using two statistical classifiers - a support vector machine (SVM) and bagging with logistic regression as the base learner (BLR). Cyst type was correctly predicted from among four classes of odontogenic cysts between 83.8% and 92.3% of the time with an SVM and between 90 ± 0.92% and 95.4 ± 1.94% with a BLR. One particular cyst type was associated with the majority of misclassifications. Omission of this cyst type from the data set improved the classification rate for the remaining three cyst types to 96.2% for both SVM and BLR. Copyright © 2013 Elsevier Ltd. All rights reserved.

  8. Laryngeal Cysts in Adults: Simplifying Classification and Management.

    2017-12-01

    Objective Laryngeal cysts may occur at any mucosa-lined location within the larynx and account for 5% to 10% of nonmalignant laryngeal lesions. A number of proposed classifications for laryngeal cysts exist; however, no previously published classification aims to guide management. This review analyzes contemporary laryngeal cyst management and proposes a framework for the terminology and management of cystic lesions in the larynx. Data Sources PubMed/Medline. Review Methods A primary literature search of the entire Medline database was performed for all titles of publications pertaining to laryngeal cysts and reviewed for relevance. Full manuscripts were reviewed per the relevance of their titles and abstracts, and selection into this review was according to their clinical and scientific relevance. Conclusion Laryngeal cysts have been associated with rapid-onset epiglottitis, dyspnea, stridor, and death; therefore, they should not be considered of little significance. Symptoms are varied and nonspecific. Laryngoscopy is the primary initial diagnostic tool. Cross-sectional imaging may be required, and future use of endolaryngeal ultrasound and optical coherence tomography may revolutionize practice. Where possible, cysts should be completely excised, and there is growing evidence that a transoral approach is superior to transcervical excision for nearly all cysts. Histology provides definitive diagnosis, and oncocytic cysts require close follow-up. Implications for Practice A new classification system is proposed that increases clarity in terminology, with the aim of better preparing surgeons and authors for future advances in the understanding and management of laryngeal cysts.

    Intradiploic arachnoid cysts have scarcely been reported in the literature, most reported cases being secondary to trauma. Non traumatic arachnoid cysts are quite rare and have been reported mostly in adults. Here, we report the case of a 16-year-old male presenting with a slowly growing mass in the occipital region and intermittent headaches. On the basis of the findings of X-rays, computed tomography scans, and magnetic resonance imaging scans of the head, the mass was diagnosed as a giant intradiploic arachnoid cyst.

    Intraspinal neurenteric cysts are rare congenital lesions that results from abnormal separation of germ layers in the third week of embryonic development, which may cause spinal compression. Although, the diagnosis of neurenteric cyst was very difficult prior to operation, MRI has proven to be a useful imaging modality in detection, localization and characterization of intraspinal neurenteric cysts. We recently experienced intraspinal neurenteric cyst in two patients who presented with progressive guadriparesis. Myelography, CT myelography and MRI were taken and complete excision was performed. The MRI findings are presented and the literature is reviewed

    Baker's cysts are rare cause of peripheral nerve entrapment and only a few cases of tibial nerve entrapment resulting from the popliteal cyst in the calf muscle have been reported in the literature. We present a case of rheumatoid arthritis complicated by a Baker's cyst with a tibial nerve entrapment. It is important to diagnose a Baker's cyst early and to differentiate it from thrombophlebitis, a popliteal aneurysm, tumor or muscle tear to effect optimal therapy and to obviate a potential neuropathy. Prompt recognition of these cases may save the patients unnecessary procedures and delay in treatment.

    A 63-year-old male presented with a round-shaped floater and visual obscuration in the right eye. Clinical evaluation showed a nonpigmented vitreous cyst connected to a lattice degeneration by a stalk. Immunostaining of the vitreous cyst obtained from vitrectomy showed its origin of retinal neuroepithelium. The cyst was formed by continuous vitreous traction, which might tear up the disrupted retina at the area of lattice degeneration. This report added the lattice degeneration to the list of causes for the acquired vitreous cyst. [Ophthalmic Surg Lasers Imaging Retina. 2017;48:856-858.]. Copyright 2017, SLACK Incorporated.

    The effect of chlorine concentration on Giardia lamblia cyst viability was tested under a variety of conditions. The ability of Giardia cysts to undergo excystation was used as the criterion of viability. The experimental variables employed included temperature (25, 15, and 5°C), pH (6, 7, and 8), chlorine-cyst contact time (10, 30, and 60 min), and chlorine concentration (1 to 8 mg/liter). In the pH range studied, cyst survival generally was observed to increase as buffer pH increased. Water...

    Full Text Available Paratubal cysts are asymptomatic embryological remnants. These cysts are usually diagnosed during adolescence and reproductive age. In general, their sizes are small but can be complicated by rupture, torsion, or hemorrhage. Paratubal cysts are often discovered fortuitously on routine ultrasound examination. We report a 19-year-old female patient who presented with irregular menses and abdominal pain. Ultrasound examination revealed a huge cystic mass at the right adnexial area. The diagnosis was confirmed as paratubal cyst during laporotomy and, hence, cystectomy and right salpingectomy were performed. [Cukurova Med J 2016; 41(3.000: 573-576

    Full Text Available Parathyroid cysts constitute 0.08–3.41% of all parathyroid masses. Intrathyroidal parathyroid cysts, however, are rare conditions with only a few cases being reported. Most of the parathyroid cysts are found to be nonfunctional and functional cysts are generally thought to be due to cystic degeneration of parathyroid adenomas. A cystic, smooth contoured lesion of 24 × 19 × 16 mm was observed in left thyroid lobe of a 76-year-old woman during ultrasonography which was performed as routine workup for primary hyperparathyroidism. It was defined as a cystic thyroid nodule at first. Tc99m sestamibi scintigraphy was performed to see any parathyroid lesions, but no radioactive uptake was observed. Intact parathormone (iPTH level was found to be >600 pg/mL in cyst aspiration fluid. Left lobectomy was performed, with a diagnosis of primary hyperparathyroidism due to functional parathyroid cyst. Serum iPTH level was decreased >50% postoperatively and histopathological evaluation was consistent with an encapsulated parathyroid adenoma with a cystic center. Parathyroid cysts are among rare causes of primary hyperparathyroidism. Diagnosis is made by markedly increased iPTH level in cyst fluid and observation of parathyroid epithelium lining the cyst wall.

    Headache is the most common symptom of colloid cysts, Rathke cysts, and craniopharyngioma due to their location in the midline, being extra-axial and typically presenting in the parasellar region. Although these tumors are generally considered benign, each has its typical characteristics defined by its location and histology. These individual characteristics define whether surgery is necessary at all and if so, the preferred surgical approach and resection's totality. The histopathological findings primarily indicate that embryonic malformations-at the first glance, ectodermal in nature-cause these tumors. Due to the fact that these disturbances occur at the boundary between ectodermal stomodeum and endodermal cephalogaster, however, does leave some doubts.

    Full Text Available Radicular cyst is the most common odontogenic cystic lesion of inflammatory origin. It is also known as periapical cyst, apical periodontal cyst, root end cyst, or dental cyst. It arises from epithelial residues in the periodontal ligament as a result of inflammation. The inflammation usually follows the death of dental pulp. This paper presents a case report of a patient with radicular cyst associated with a primary molar.

    Neurocysticercosis (NCC), Taenia solium larval infection of the brain, is an important cause of acquired seizures in endemic countries, which relate to number, location and degenerating cysts in the brain. Multicyst infections are common in endemic countries although single-cyst infection prevails in India. Single-cyst infections in an endemic country suggest a role for host immunity limiting the infection. This study examined ex vivo CD4(+) T cells and in vitro Th1 and Th2 cytokine responses to T. solium cyst antigens of peripheral blood mononuclear cells of healthy subjects from endemic and nonendemic regions and of single- and multicyst-infected patients for association with cyst burden of NCC. T. solium cyst antigens elicited a Th1 cytokine response in healthy subjects of T. solium-endemic and T. solium-non-endemic regions and those with single-cyst infections and a Th2 cytokine response from subjects with multicyst neurocysticercosis. Multicyst neurocysticercosis subjects also exhibited low levels of effector memory CD4(+) T cells. Th1 cytokine response of T. solium exposure and low infectious loads may aid in limiting cyst number. Th2 cytokines and low effector T cells may enable multiple-cyst infections to establish and persist. © 2016 John Wiley & Sons Ltd.

    To characterize clinical signs and histologic findings in dogs with odontogenic cysts and determine whether histologic findings were associated with clinical features. Retrospective case series. 41 dogs. Medical records were reviewed to obtain clinical data, including breed, age, sex, and lesion location. Microscopic sections and results of diagnostic imaging were reviewed. Odontogenic cysts were identified in 41 dogs between 1995 and 2010. There were 29 dogs with dentigerous cysts, 1 with a radicular cyst, 1 with a lateral periodontal cyst, and 1 with a gingival inclusion cyst. In addition, 9 dogs with odontogenic cysts that had clinical and histologic features suggestive of, but not diagnostic for, odontogenic keratocysts seen in people were identified. In all 9 dogs, these cysts were located in the maxilla and surrounded the roots of normally erupted teeth. Of the 29 dogs with dentigerous cysts, 23 had a single cyst, 5 had 2 cysts, and 1 had 3 cysts. Six cysts were associated with an unerupted canine tooth, and 30 were associated with an unerupted first premolar tooth (1 cyst was associated both with an unerupted canine tooth and with an unerupted first premolar tooth). Dentigerous cysts were identified in a variety of breeds, but several brachycephalic breeds were overrepresented, compared with the hospital population during the study period. Results suggested that a variety of odontogenic cysts can occur in dogs. In addition, cysts that resembled odontogenic keratocysts reported in people were identified. We propose the term canine odontogenic parakeratinized cyst for this condition.

    The loss during desiccation of osmotically active water (OAW), which freezes during cooling to -45 degrees C, and osmotically inactive water (OIW), which remains unfrozen, from the cysts of the potato cyst nematode, Globodera rostochiensis, was determined using differential scanning calorimetry. Exotherms and endotherms associated with non-egg compartments were not detected after 5 min desiccation at 50% relative humidity and 20 degrees C. The pattern of water loss from the cysts indicates that water is lost from compartments outside the eggs first, that nearly all the non-egg water is OAW and that the OIW content of the cyst is contained within the eggs. Water is lost from the eggs only after the OAW content outside the eggs falls below that within the eggs. Both OAW and OIW are lost from the eggs during desiccation but the eggs retain a small amount of OIW. Other animals which survive some desiccation but which are not anhydrobiotic will tolerate the loss of OAW but not the loss of their OIW. Anhydrobiotic animals can survive the loss of both their OAW and a substantial proportion of their OIW.

    Full Text Available O cisto nasolabial é um cisto não odontogênico raro que se desenvolve na região inferior da asa nasal, com patogênese ainda incerta. Esta lesão, que possui crescimento lento e dimensões variáveis (1,5-3cm, caracteriza-se clinicamente por uma tumefação flutuante na região do sulco nasolabial ao redor da asa do nariz, causando uma elevação do lábio superior. Seu diagnóstico pode ser feito basicamente pelo quadro clínico e, se necessário, complementando-se com exames auxiliares por imagens. O presente trabalho relata o caso de uma paciente do sexo feminino de 48 anos, que se queixava da presença de uma massa consistente na região da asa esquerda do nariz e cujas características clínicas eram compatíveis com cisto nasolabial. As imagens de TC demonstraram uma formação expansiva com densidade de tecido mole, localizadas na região nasal esquerda medindo cerca de 1,2cm de diâmetro e apresentando contornos nítidos e bem definidos e densidade homogenia ao redor de 50 UH. Já as imagens de RM mostraram uma lesão de aspecto circular localizada em tecido mole, apresentando hiperintensidade nas imagens ponderadas em T1, T2 e no recurso de supressão da gordura, sendo a hipótese diagnóstico de cisto nasolabial, confirmado pelo exame histopatológico depois da cirurgia.The nasolabial cyst is an uncommon non-odontogenic cyst that develops in the lower region of the nasal ala; its pathogenesis is uncertain. This lesion grows slowly and measures between 1.5 and 3 cm; it is characterized clinically by a floating tumefaction in the nasolabial sulcus, which elevates the upper lip. The diagnosis is based on the clinical findings and, if necessary, image exams. This paper reports a case of a white 48-year-old Brazilian female patient that presented a firm tumor in the left ala of the nose; the clinical features suggested a nasolabial cyst. CT scans revealed an expanding tumor with soft tissue density located in the left ala of the nose

    Background: Utilization of multidetector-row CT (MDCT) is anticipated to improve the diagnostic accuracy and reliability for determining malignant cysts. Purpose: To assess the diagnostic accuracy, interobserver agreement, benefit of consensus reading, and strong predictors of malignancy in determining malignant cystic renal masses at MDCT. Material and Methods: Two radiologists independently rated the probability of malignancy at MDCT in 72 benign and 53 malignant cysts. The accuracy and interobserver agreement for determining malignant cysts were evaluated. The strong predictors of malignancy were determined, and in patients with interobserver disagreement for determining malignant cysts, consensus readings were performed. Results: Az value of the two readers was 0.905-0.936 and the sensitivity and specificity were 85-89% and 83-93%, respectively. The overall interobserver agreement for determining the malignant cyst was good as the κ value was 0.696 (% agreement, 61% (76/125)). Thickened irregular wall, thickened irregular septa, and enhancing soft tissue component were strong predictors for malignancy with both readers. In the 17 patients with interobserver disagreement for determining malignant cysts, the sensitivity was improved from 38-63% to 89% by the consensus reading. Conclusion: At MDCT, some false negative decisions for determining malignant cysts can be corrected by consensus reading, and thickened irregular septa, thickened irregular wall, and enhancing soft tissue component are the strong predictors of malignant cysts

    The purpose of this study was to evaluate the prevalence of 680 odontogenic cysts diagnosed in Porto Alegre, RS, Brazil, and to compare results with findings in the literature. Data of odontogenic cysts diagnosed from 1985 to 2005 were collected from the files of the Oral Pathology Laboratory of Pontifícia Universidade Católica do Rio Grande do Sul, Porto Alegre, RS, Brazil, and entered in a standardized form for later comparisons. The most prevalent odontogenic cysts were radicular (72.50%), dentigerous (22.20%) and residual (4.26%) cysts. The mandible of white patients was the anatomic site and ethnic group most frequently affected by this disease. Four of the six types of cysts were more frequent in the second and fourth decades of life, and no significant differences were found between sexes in the diagnosis of odontogenic cysts. In conclusion, the prevalence of odontogenic cysts was similar to that reported in the literature, which shows that inflammatory cysts are the most frequent.

  1. Diagnosis and management of simple ovarian cysts: an audit

    Simcock, B.

    2005-01-01

    Simple ovarian cysts are common. The aim of clinical management is to optimize the treatment of malignant and premalignant cysts while minimizing intervention for cysts likely to resolve spontaneously. In this retrospective study, ovarian cysts over 30 mm in diameter were detected in 90 women. Of this population, 75 were premenopausal, 13 postmenopausal, and two had undergone a hysterectomy. Thirteen women presented acutely. Family history of breast, ovary or colon cancer was not ascertained in any of the women. None had CA125 levels performed. In 22 cases, the cyst was aspirated; only 10 of these had follow-up ultrasound. Laparotomy was performed in 25 premenopausal women, the two perimenopausal women and eight postmenopausal women. Average cyst size was 71 mm (range 40-80 mm) in the laparoscopy group, and 72 mm (range 36-180 mm) in the laparotomy group. After initial diagnosis at ultrasound, a follow-up scan was performed 4-16 weeks later. The final diagnosis was ovarian neoplasm in 13 and hydrosalpinx in two. None had a malignancy. Documentation at ultrasound was often inadequate, and management of the women with an ovarian cyst was haphazard. Guidelines on management of simple ovarian cysts are likely to improve clinical practice. Copyright (2005) Blackwell Science Pty Ltd

    The presence of cysts in the white matter of the central nervous system of patients with tuberous sclerosis (TS) is an uncommon finding that has been reported only recently in neuroimaging studies. This article assesses the prevalence of these lesions in a large series of patients studied by magnetic resonance imaging (MRI) and their relationship to other epidemiological and imaging findings. MRI studies were performed in 46 patients (23 males and 23 females) with a mean age of 12.7 years, and the results were examined retrospectively in the search for cortical tubers, subependymal nodules and white matter nodules, lines and cysts. Nine patients (19.6%) presented cysts in white matter. Seven had only one cyst and the remaining two patients each had two. Multiple regression analysis relating the presence of the cysts with other neuroimaging findings in these patients revealed a statistically significant relationship only with white matter nodules (odds ratio: 7.5; p=0.006). White matter cysts are small, supratentorial lesions of deep location. There is a statistically relationship between the presence of these cysts and that of nodular lesions in the white matter. This finding supports the theory that the cyst originate from white matter nodules. (Author) 17 refs

    2007-04-01

    The effectiveness of intralesional sclerotherapy of lymphangiomas and ranulas with OK-432 (Picibanil) has been proved in several clinical studies. The aim of our study was to review the effectiveness of sclerotherapy of benign cervical cysts with Picibanil as an alternative method to surgical excision. Between March 2002 and March 2006, a prospective observational study was carried out to assess the effects of Picibanil on cervical cysts. Between 2002 and 2006 we treated 14 patients having cervical cysts through intralesional application of Picibanil with a dose of 0.01 mg/ml. So far we used Picibanil with 13 patients achieving a high success rate. In eight cases we observed, both clinically and ultrasonographically, a nearly complete regression, and a complete regression of the cysts in three cases. In two cases the cysts atrophied. In these cases only residual findings could be observed. In one case we extirpated the remaining cyst. If there is no clear reaction of the cyst to the treatment, an excision is indicated 6 weeks after the injections to gain meaningful histological examination. No significant complication after sclerotherapy with Picibanil was observed. According to our results the application of OK-432 (Picibanil) is a safe and effective primary method for sclerotherapy of benign cervical cysts which can replace surgical extirpation in special cases. However, the risk of malign diseases has to be excluded before the commencement of the Picibanil treatment.

    Full Text Available Thyroglossal duct cyst presents most frequently in the midline of the neck, either at or just below the level of the hyoid bone. They generally manifest as painless neck swelling, and they move on protrusion of tongue and during swallowing. A case of thyroglossal cyst was reported in the left submandibular region in a 14-year-old girl, above the level of hyoid bone; ultrasound examination favored a cystic lesion which moved in a vertical fashion on swallowing whereas fine needle aspiration cytology report was suggestive of simple cystic lesion of thyroglossal cyst. No lymphoid or malignant cells were present. The cyst was excised completely by surgical procedure under general anesthesia. Histopathological analysis revealed thyroglossal cyst showing columnar and flattened epithelium of cyst with focal aggregate of chronic inflammatory cells supported by fibrocollagenous cyst wall. The clinical, ultrasound, and histopathological findings suggested that the lesion was an infected thyroglossal cyst. There was no evidence of recurrence 6 months after surgery.

    Hydatid cyst or disease is an anthropozoonosis due to the development of the larval form of the taenia Echinococcus granulosus in humans. It is endemic in Morocco. The location of a hydatid cyst in the infratemporal fossa (ITF) is extremely rare. The authors report a pediatric case. An 11 year old child was admitted to hospital with a history of left latero-facial swelling gradually increasing in volume for 2 months, CT scan of the face revealed a cystic formation of 7 cm diameter sitting at the left ITF, hydatid serology was negative. A transzygomatic approach allowed the excision of the cyst. The histopathological examination of the resected specimen confirmed the diagnosis of hydatid cyst. The location at the infratemporal fossa of an expansive process such as hydatid cyst in children may have a particular impact on adjacent structures and a more meaningful clinical expression. The rate of growth of hydatid cysts is highly variable and ranges from 1 to 5 cm a year. Hydatid serology is often negative. CT examination is the gold-standard radiological examination. Surgical removal of the hydatid cyst is the most effective treatment. The transzygomatic approach allowed a sufficient access to the cyst and a good quality of excision.

    Full Text Available Abstract Pancreatic cysts are a heterogeneous group of lesions, which can be benign or malignant. Due to improved imaging techniques, physicians are more often confronted with pancreatic cysts. Little is known about the origin of pancreatic cysts in general. Von Hippel-Lindau (VHL disease is an atypical ciliopathy and inherited tumor syndrome, caused by a mutation in the VHL tumor suppressor gene encoding the VHL protein (pVHL. VHL patients are prone to develop cysts and neuroendocrine tumors in the pancreas in addition to several other benign and malignant neoplasms. Remarkably, pancreatic cysts occur in approximately 70% of VHL patients, making it the only hereditary tumor syndrome with such a discernible expression of pancreatic cysts. Cellular loss of pVHL due to biallelic mutation can model pancreatic cystogenesis in other organisms, suggesting a causal relationship. Here, we give a comprehensive overview of various pVHL functions, focusing on those that can potentially explain pancreatic cyst development in VHL disease. Based on preclinical studies, cilia loss in ductal cells is probably an important early event in pancreatic cyst development.

    Spinal bronchogenic cysts are rare findings, with only four cases of lumbar bronchogenic cysts reported in the literature. All of these bronchogenic cysts involved the conus medullaris. We present the first case of a lumbar bronchogenic cyst and arachnoid cyst arising from the cauda equina in a 68-year-old male. Uniquely, this bronchogenic cyst also contained components of an arachnoid cyst. Magnetic resonance imaging (MRI) demonstrated a compressive cystic lesion at the level of the L3 vertebra splaying the cauda equina. An L3/L4 laminectomy was performed with marsupialisation of the cyst. Histological examination revealed pseudostratified ciliated columnar epithelium confirming the diagnosis of a bronchogenic cyst, as well as a pleated fibrovascular tissue lined by sparsely spaced small monomorphic arachnoidal cells, indicating an arachnoid cyst. We demonstrate that bronchogenic cysts can be successfully treated with marsupialisation.

    Several cell types are associated with the development of cystic and tumoral odontogenic lesions. Among inflammatory cells, mast cells can be associated with their pathogenesis. The aim of this study was to analyze mast cells in periapical cysts, dentigerous cysts, and keratocystic odontogenic tumors. Tissue sections were submitted to toluidine blue staining and immunohistochemistry with antibody anti-tryptase (clone G3). Mast cells were quantitated using Image-Pro Plus software to obtain the mean number of mast cells in three regions: epithelial, superficial portion of the fibrous wall and deep portion of the fibrous wall from 20 periapical cysts, 20 dentigerous cysts (six non-inflamed and 14 inflamed) and 20 keratocystic odontogenic tumors (four non-inflamed and 16 inflamed). The mean number of mast cells detected per lesion by immunohistochemistry (4.1) was higher than by histochemistry (1.5) (Pcysts and keratocystic odontogenic tumors showed a higher mean number of mast cells than non-inflamed lesions in all regions. The deep region from all cysts showed the highest mean number of degranulated mast cells, except for non-inflamed keratocystic odontogenic tumors analyzed by immunohistochemistry. Immunohistochemical staining detected higher number of mast cells than histochemistry. The higher number of mast cells observed in inflamed lesions could indicate the participation of these cells in the inflammatory response in odontogenic lesions. The prevalence of degranulated mast cells in the deep region suggests intense activity of these cells, possibly related to growth of cystic lesions. © 2012 John Wiley & Sons A/S.

  1. A contribution to the diagnosis of the small dentigerous cyst or the paradental cyst

    Full Text Available The aim of this study was to verify the relationship between the radiographically measured width of the pericoronal space (PS and the microscopic features of the follicle in order to contribute to the diagnosis of small dentigerous cysts and paradental cysts. One hundred and thirty unerupted teeth (UT and thirty-five partially erupted teeth (PET were radiographed and extracted. The radiographic analysis consisted of measuring the width of the PS. The results of the radiographic analysis were compared with those of the histopathologic examination of the dental follicle. The width of the PS ranged from 0.1 to 5.6 mm. The most frequently observed lining of the follicles was a reduced enamel epithelium (REE (68.4% in UT and a hyperplastic stratified squamous epithelium (HSSE (68.5% in PET. Inflammation was present in 36.1% of the UT and in 82.8% of the PET. There was a statistically significant association between the presence of stratified squamous epithelium (SSE and PS enlargement for UT (p < 0.05. There was a tendency of association between inflammation and PS enlargements in PET and, possibly, in UT, despite the absence of statistical significance. Surgically, we did not detect bone cavitation or luminal cystic contents in pericoronal spaces smaller than 5.6 mm. We suggest that the first radiographic diagnosis for a PS enlargement, in most of the routine clinical cases, should be of "inflammation of the follicle". The hypothesis of "dentigerous cyst" or "paradental cyst" is suggested as a second diagnosis. The final differential diagnosis between a small dentigerous or a paradental cyst and a pericoronal follicle depends on clinical and/or surgical findings, such as the presence of bone cavitation and cystic content.

  2. Branchial cysts within the parotid salivary gland

    2012-01-01

    Cystic lesions within the parotid gland are uncommon and clinically they are frequently misdiagnosed as tumours. Many theories have been proposed as to their embryological origin. A 20-year retrospective review was undertaken of all pathological codes (SNOMED) of all of patients presenting with any parotid lesions requiring surgery. After analysis seven subjects were found to have histopathologically proven parotid branchial cysts in the absence of HIV infection and those patients are the aim of this review. Four of the most common embryological theories are also discussed with regard to these cases, as are their management. PMID:22607735

    Twelve cases of subchondral synovial cysts (intra-osseous ganglion) have been seen and their clinical features, radiological findings and differential diagnosis are described. The lesion is a benign cystic tumour-like mass in the subchondral portion of a synovial joint. Our findings in respect of age, sex and localisation are compared with those of other authors. The aetiology and pathogenesis of the lesion is not completely understood. There is an increased incidence in middle life and joints with high dynamic and static stress are favoured, particularly in the lower extremities. Chronic stress or microtrauma, causing damage to the involved joint, therefore appears to be a plausible explanation. (orig.) [de

    A patient is presented with widespread primary hydatid cysts in spinal-paraspinal locations, secondary to Echinococcus granulosus. An alternative mechanism to explain how the embryos gained access to the body is proposed: The embryos penetrated the intestinal muscle and may have directly entered into the inferior vena cava system through small venous connections between this system and portal circulation. Various conditions in daily life associated with Valsalva maneuver might have caused such an atypical passage of the embryos to the inferior caval system toward the retroperitoneum and spinal-paraspinal structures via lumber epidural venous plexuses.

    Full Text Available Lymphoepithelial cyst (LEC is the most commonly encountered congenital neck pathology in the lateral part of the neck. A 66-year-old woman presented to the ENT clinic due to difficulty in swallowing persisting for approximately 1 year. Magnetic resonance imaging revealed a cystic mass at right tonsil. Surgery was performed due to this unilateral tonsillar mass, which was excised together with the right tonsil. LEC was diagnosed at histopathological examination. LEC in the palatine tonsil is rare, and only a few cases have been reported in the literature. We report a rare case of LEC in the palatine tonsil.

    The aim of the present study was to review the magnetic resonance (MR) appearance of primary epithelial cysts in order to distinguish the cysts from other possible lesions. MR images were obtained in 27 cases of epithelial cysts, including 7 odontogenic keratocysts, 3 dentigerous cysts, 1 glandular odontogenic cyst, 10 radicular cysts, 4 nasopalatine duct cysts, and 2 nasolabial cysts. In addition, contrast enhanced MR imagings were performed in 12 cases, including 3 odontogenic keratocysts, 1 dentigerous cyst, 1 glandular odontogenic cyst, and 7 radicular cysts. We obtained the following results on the basis of the above MR and contrast enhanced MR findings. (a) Odontogenic keratocysts had a predilection for intermediate-high signal intensity (SI) on T1-weighted images (WI) and heterogeneous low-high SI on T2WI. (b) Dentigerous cysts, glandular odontogenic cyst, radicular cysts and nasolabial cysts showed the same predilection with the SI, which were homogeneous intermediate SI on T1WI and homogeneous high SI on T2WI. (c) The MR images of the nasopalatine duct cysts, which showed homogeneous high SI on T1WI, were specific. (d) The Gd-T1WI would be useful in decisively differentiating odontogenic cysts, which showed rim-enhancement, from tumors consisting of solid components. In conclusion, we were able to obtain more information from the MR and contrast enhanced MR images than from conventional radiograph findings

    1986-01-01

    Synovial cysts in an intraspinal location, associated with facet joint osteoarthritis, have been diagnosed using CT. Surgical removal of the cyst, when believed to be the cause of radiculopathy, has resulted in symptomatic relief. The authors have applied a nonoperative treatment method consisting of CT-guided needle placement in the facet joint adjacent to the cyst, followed by injection of contrast material and corticosteroids. Three patients were treated without complications and with complete relief of symptoms in two cases and partial relief in one, although no decrease in the size of the cysts was demonstrated on follow-up CT scans. The preliminary results indicate a possible role for this treatment technique in patients with intraspinal synovial cysts

    Maxillary bone epithelial cyst is rare in dogs. A 5-year-old, spayed female miniature schnauzer developed a swelling below the nasal canthus of left eye. Plain radiograph demonstrated a 1.5 cm diameter of radiolucent lesion on the maxillary bone anteroventral to the eye, and contrast dacryocystorhinography confirmed an obstructed nasolarcrimal duct. The swelling showed poor response to antibiotic treatment but responded well to oral prednisolone. Exploratory surgery revealed a cyst-like structure filled with brown serous fluid. Histopathological examination of the removed cyst revealed a double cuboidal epithelial cyst. The dog recovered rapidly after surgery, and the swelling had not recurred for a 36-month follow-up. It is the first case of periorbital bone epithelial cyst reported in an adult miniature schnauzer.

    Full Text Available Background. Even though branchial cleft cysts are currently accepted as a congenital anomaly, there is often a long delay until clinical presentation; branchial cleft cysts classically appear in the second to fourth decade of life. Our observation of their occurrence in three pregnant women encouraged us to contemplate a possible hormonal influence. Methods. Immunohistological analysis was performed for the evaluation of the estrogen receptor alpha (ERα in paraffin-embedded tissue specimens of 16 patients with a diagnosis of branchial cleft cyst, with three of them being pregnant. Results. Expression of ERα was detected within epithelial cells only in branchial cleft cysts in pregnant females; moreover, higher growth fractions (Ki-67/Mib1 were found. Conclusion. The fact that the estrogen receptor was expressed only in pregnant women, in contrast to 13 investigated cases, may suggest that the high level of estrogen in pregnancy is a possible explanation for the spontaneous growth of branchial cleft cysts.

    2017-01-01

    Full Text Available Cystic echinococcosis (CE is an important helminthic zoonotic disease that commonly affects the liver and lungs. Imaging methods and serology establish the diagnosis in most cases. Chest x-ray can diagnose uncomplicated pulmonary hydatid cysts, whereas superinfection and/or rupture of the hydatid cyst (complicated cysts may change the radiographic appearance and lead to delayed diagnosis and treatment. We report the case of a patient with hemoptysis and chest pain, where computer tomography scan of the lung suggested a large, ruptured hydatid cyst. However, serological tests with indirect hemagglutination (IHAfor Echinococcus granulosus antibodies were negative, and there was massive growth of Streptococcus pneumoniae in sputum. Based on this, we concluded that the patient had a bacterial lung abscess. The diagnosis of CE was only made after surgical removal of the cyst followed by microscopy and polymerase chain reaction.

    The authors have interpreted one patient's full mouth intra-oral films, oblique-lateral film of the left mandible and orthopantomograph which revealed 6 radicular and 1 residual cysts. As results of interpretation of these serial films, we have drawn following conclusions: 1. Radicular cyst arose from the cell rests contained in an apical granuloma which was sequel to advanced pulpitis due to dental caries. 2. Radicular cyst was developed from remaining cell rests after the extraction of a tooth with such a radicular cyst of apical dental granuloma. 3. Cyst grew in size by absorption of fluid into cystic cavity due to difference in osmotic pressure between the cystic fluid and adjacent tissue fluid.

    Full Text Available Hydatid disease is one of the oldest diseases known to mankind. In 85-95% of the cases, the liver and/or the lung are involved and in only 5-15% the cyst occurs at the other sites. Echinococcal cysts are mostly found in the liver (60%-70% of cases, followed by the lungs (10%-25%, spleen, ovaries, kidneys, brain, bones and heart, but rarely elsewhere in the body. 1-3 Retroperitoneal location of hydatid cyst is encountered rarely and only occasional case reports have appeared since Lockhart and Sapinza first reported this entity in 1958. 4-6 Primary retroperitoneal hydatid cyst is extremely rare. Hydatid disease in extrahepatic locations usually remains asymptomatic unless the cyst grows and produces.

    2010-01-01

    The p53 is a well-known tumor suppressor gene, the mutations of which are closely related to the decreased differentiation of cells. Findings of studies on immunohistochemical P53 expression in odontogenic cysts are controversial. The present study was carried-out to investigate the immunohistochemical expression of P53 protein in odontogenic cysts. Thirty paraffin blocks of diagnosed odontogenic cysts were processed to determine the immunohistochemical expression of P53 protein. Nine of the 11 odontogenic keratocysts (81.8%) expressed P53, one of three dentigerous cyst cases expressed P53, while none of the 16 radicular cysts expressed P53 protein. The findings of the present work supported the reclassification of OKC as keratocystic odontogenic tumor. PMID:23960493

    Background: Expression of CD10 has been documented in various tumors like nasopharyngeal carcinoma, gastric carcinoma, squamous cell carcinoma, odontogenic tumors. Aim: To evaluate and compare CD10 expression in odontogenic cysts like radicular cyst, dentigerous cyst and odontogenic keratocyst (OKC). Materials and Methods: Total 60 cases were included in the study, comprising 20 cases each of radicular, dentigerous and odontogenic keratocyst. Each case was evaluated and compared for immunohistochemical expression of CD10. Results obtained were statistically analysed using ANOVA test followed by post hoc test Tukey-Kramer Multiple Comparisons Test for continuous variable and Chi-square test for discrete variable. Results: More number of cases showing sub-epithelial stromal CD10 expression were found in OKC among the cysts. Conclusion: CD10 expression was more in OKC compared to radicular and dentigerous cysts. PMID:25584313

    Full Text Available Hydatid disease is still prevalent in developing countries, and isolated cardiac hydatid cysts are the rarest presentation. We report a 40-year-old nondiabetic, nonhypertensive female who presented with low-grade fever for 2 months shortness of breath and orthopnea for 2 weeks. Transthoracic echocardiography revealed a large, round cystic lesion with multiple daughter cysts without any obvious intraluminal detached membranes with mass effect on the left ventricular outflow tract. After total excision, residual tissue was closed with Teflon patch. Germinative membrane and hundreds of daughter cysts were seen. Following total excision of the cyst from myocardium, myocardial cavity was washed thoroughly with 10% Betadine solution. Pathological examination confirmed the diagnosis of hydatid cyst. Preoperatively started albendazole was continued for 4 weeks even after the operation. On follow-up after 4 weeks, the patient is doing well and cardiac imaging showed normal contours of the heart.

    1988-01-01

    The congenital subglottic hemangioma typically appears as an asymmetric subglottic narrowing or mass on frontal neck radiograph. Therefore, soft tissue neck radiography has been advocated as a definitive non-operative approach for diagnosing these lesions. However, we have noted similar asymmetric subglottic narrowing in patients with acquired subglottic cysts. These retention cysts occur following long-term intubation in the neonate. The mechanism probably involves subglottic fibrosis which obstructs glands with subsequent cyst formation. Acquired subglottic cysts typically appear as an asymmetric narrowing on frontal or lateral soft tissue neck radiographs. These lesions may produce airway compromise but are effectively treated by forceps or laser removal. Acquired subglottic cysts must be included in the differential diagnosis of asymmetric subglottic narrowing. The definitive diagnosis is made by direct laryngoscopy, not soft tissue neck radiograph.

    1991-05-01

    This report documents the danger of the gravid uterus fixing a large ovarian cyst in a position disadvantageous to diaphragmatic excursion and thereby obstructing ventilation. A 34-year-old pregnant patient presented at 18 weeks amenorrhoea with a large ovarian cyst. She gave a history of exertional dyspnoea and orthopnoea. Clinical examination revealed a grossly enlarged abdomen and a respiratory rate of 28 breaths.min-1. Intraoperatively, ventilation was markedly impaired resulting in cyanosis and bradycardia. This was relieved by drainage of the ovarian cyst. A left lateral tilt with manual traction on the tumour may have avoided this problem. Should the above measures be inadequate, immediate drainage of the cyst is essential. Severe respiratory distress may require ultrasound-guided, percutaneous, aspiration of the cyst preoperatively. However, as in this patient, the absence of gross signs of respiratory failure does not preclude acute ventilatory failure after induction of anaesthesia.

    The radicular cyst is an inflammatory odontogenic cyst of endodontic origin. Radiographically, the lesion appears as a periapical radiolucent image. This report describes a very rare case of a mixed periapical radiographic image diagnosed as a radicular cyst. A 37-year-old female patient presented a mixed, well-circumscribed image located in the periapical region of the left maxillary central incisor, which presented unsatisfactory endodontic treatment. Microscopic examination revealed a cavity lined by non-keratinized squamous epithelium and extensive calcifications in the cystic lumen and lining epithelium. Diagnosis of radicular cyst with extensive calcifications was established. Endodontic retreatment was performed and no radiographic signs of recurrence were observed 18 months after treatment. Although very rare, a radicular cyst should be considered in the differential diagnosis of a mixed periapical image associated to teeth with pulp necrosis.

    A 23-years old man, complaining of two weeks febrile period, general weakness, easy fatigue, breathlessness and lost of weight was admitted. Hepatomegaly, ascite, leg edema were observed. Abdominal computed tomography revealed a great number of hydatid cysts in the liver, spleen and peritoneum. The patient was treated with Albendazole, given at a dose of 10 mg/kg/day for six months. After one and half month of therapy the clinical status of the patient considerably improved, US and Computed tomography examination showed a decrease in size of the larger cysts, changes in cyst structure and disappearance of the smaller cysts. One and half year later almost ail cysts disappeared completely, the remaining represented some irregular spots with marked density. The results showed that Albendazole has rapid curative effect in patients with multiple abdominal echinococcosis. (authors)

    To evaluate the ultrasonographic (US) or computer tomography (CT) findings of surgically proven epidermal cysts in the trunk, and to compare the echogenicity of cysts with internal contents. Forty-five patients were retrospectively evaluated. US and CT findings of epidermal cysts were assessed in regard to location, size, shape, number, echogenicity, posterior sound enhancement, internal density, septa, mural nodule and calcification, perilesional infiltration, contrast enhancement, and internal contents. All 45 patients (M:F=29:16; US in 26, CT in 19) had only one cyst, and they were located in the buttocks (n=19), back (n=13), inguinal (n=4), posterior neck (n=3), perineum (n=2), abdominal wall (n=2), presternal (n=1), and axilla (n=1). Of 26 patients who underwent US, there were 8 cases of homogeneously hypoechoic mass (30.8%), 8 of inhomogeneously hypoechoic mass (30.8%), 7 of homogeneously hypoechoic mass with internal hypoechoic lines and echogenic spots (26.9%) and 3 of homogeneously hypoechoic mass with internal echogenic spots (11.5%). Posterior sound enhancement was noted in 21 patients (80.8%). Of 19 patients who underwent CT, there were 14 cases of simple cyst (73.7%) and 5 of abscess-like lesion (26.3%). Overlying skin thickening (n=13), contrast enhancement of cystic wall (n=11), perilesional infiltration (n=7), and internal septa (n=6) were demonstrated. The internal contents of the cysts were keratinous (n=27, 60.0%) or greasy (n=15, 33.3%) material. There was no statistical significance between the echogenicity of the cysts and the internal contents (p > 0.2). Epidermal cysts showed homogeneous or inhomogeneous hypoechoic mass with posterior sound enhancement on US. There was no relationship between the echogenicity of the cysts and the internal contents. In the case of ruptured cyst, an abscess-like lesion with wall enhancement and perilesional infiltration was noted on CT scan

    To evaluate percutaneous short-term catheter drainage in the management of benign ovarian cysts in patients at increased surgical risk. Thirty-eight patients with simple ovarian cysts were treated with drainage of fluid content by catheters until output stopped. All patients were poor candidates for surgery. All procedures were performed under ultrasonographic (US) control and local anesthesia. Cytologic examination was performed in all cases. The patients were followed up monthly with color Doppler US for 12 months. Outcome measure was the recurrence of a cyst. During the 12-month follow-up period, 10 of 38 cysts recurred. Seven of the 10 cysts required further intervention, and three were followed up without intervention. Four of the seven patients who required further intervention underwent repeat transabdominal aspiration and three declined repeat aspiration and subsequently underwent surgery. After repeated aspirations, two of four cysts disappeared, one necessitated follow-up only, and one necessitated surgical intervention. Cyst volume (P = .009) and diameter (P = .001) were significantly larger in the cysts that recurred. No evidence of malignancy was reported in the cytologic examination in any patient. No patients developed malignancy during follow-up. No major complications were observed. The hospital stay was 1 day for all patients. The median duration of drainage in the groups with resolved and recurrent cysts was 1 day (interquartile range, 1-1) and 2 days (interquartile range, 1-3), respectively (P = .04). In patients considered poor candidates for open surgery or laparoscopy, percutaneous treatment of ovarian cysts with short-term catheter drainage without sclerotherapy appears to be a safe and effective alternative, with low recurrence rates.

    Full Text Available BACKGROUND Trichilemmal cysts or pilar tumours are slow growing scalp lesion commonly found in elderly women. These slow growing lesions may cause morbidity and even mortality. Recurrence of the lesions after local excision is common. These trichilemmal cyst usually indolent with benign nature or may transform to proliferating trichilemmal cyst or Proliferating Pilar Tumour (PPT or may show malignant transformation. The aim of the study is to study the radiological and pathological evaluation of trichilemmal cysts of scalp. MATERIALS AND METHODS A hospital-based cross-sectional retrospective study was conducted. The study group comprised of 20 patients presenting to the Departments of Radiodiagnosis, Radiotherapy, General Surgery, Plastic Surgery and Dermatology in a tertiary care hospital from July 2015 to August 2017. All patients were initially evaluated clinically followed by cross-sectional imaging modality like Computed Tomography (CT or Magnetic Resonance Imaging (MRI. RESULTS In 20 patients, a total of 51 trichilemmal cysts were evaluated where 46 (90.2% were benign trichilemmal cysts and 5 (9.8% showed malignant transformation. The mean age of presentation was 47.9 yrs. ± 1.5 (SD with male:female ratio of 1:3.The mean duration of presence of trichilemmal cyst was 5.9 yrs. ± 3.2 (SD. Out of 5 malignant trichilemmal cysts 3 patients (15% showed bony calvarial erosion and 2 patients (10% showed intracranial extensions. Statistical significance with ‘p’ value of 0.003 was noted between the size of largest dimension of trichilemmal cyst and their histopathology without any statistical significance between duration of swelling and their histopathology. CONCLUSION Even though, the trichilemmal cysts of scalp are denoted as benign lesion, as they usually shows recurrence and its affinity to become locally aggressive and turn into malignancy is there. Hence, clinical, radiological and pathological correlation isnecessary to decreased

    Concerning the hypothesis that distinct types of salivary gland cysts may be the starting point of a salivary gland tumour, a histological examination of 1,661 salivary gland cysts was performed in order to analyse the cell types and their proliferative activity. Epithelial alterations were found especially in salivary duct cysts of parotid gland and in mucous retention cysts of minor salivary glands. Characteristic cellular changes were epithelial metaplasias (goblet cells, clear cells, squamous cells) and focal epithelial proliferations with plump or papillary plaques projecting into the cyst lumen. Only in one case had a mucoepidermoid carcinoma developed in the wall of a parotid duct cyst. The epithelial metaplasia and focal proliferative activity in salivary duct cysts is comparable to similar alterations in odontogenic cysts as possible early manifestation of a tumour, especially of an ameloblastoma or mucoepidermoid carcinoma. The differential diagnosis of salivary duct cysts must take primarily cystadenomas and cystic mucoepidermoid carcinomas of well-differentiated type into account.

    Intracranial fat-containing congenital tumors are characterized by negative absorption values on CT. We hereby report a case of an epidermoid cyst with subarachnoid free fats diagnosed preoperatively by CT. A 21-year-old female was admitted to our hospital because of continuous mild headache and nausea. At the time of admission, the results of her physical and neurological examinations were normal. CT, however, demonstrated multiple subarachnoid low-density spots and a suprasellar low-density area with high-density spots. In addition, there were negative absorption values (-12 -- -77), suggesting free fats. A spontaneously ruptured epidermoid or dermoid cyst was diagnosed on the basis of these findings. At surgery, a suprasellar tumor containing a yellowish, cheese-like material was confirmed. The patient made an uneventful recovery and was discharged 14 days after surgery. There have been several published reports of CT appearances of intracranial fat-containing tumors. However, spontaneously ruptured cases diagnosed by CT are rare. CT was found to be useful for the diagnosis of spontaneously ruptured cases of fat-containing tumors.

    The soybean cyst nematode (SCN), Heterodera glycines Ichinohe (Phylum Nematoda), is a major pathogen of soybean. It causes substantial yield losses worldwide and is difficult to control because the cyst protects the eggs which can remain viable for nearly a decade. Crop rotation with non-host crops and use of biocontrol organisms such as fungi and bacteria offer promising approaches, but remain hampered by lack of knowledge of the biology of nematode parasitic organisms. We used a high-throughput metabarcoding approach to characterize fungal communities associated with the SCN cyst, a microenvironment in soil that may harbor both nematode parasites and plant pathogens. SCN cysts were collected from a long-term crop rotation experiment in Southeastern Minnesota at three time points over two growing seasons to characterize diversity of fungi inhabiting cysts and to examine how crop rotation and seasonal variation affects fungal communities. A majority of fungi in cysts belonged to Ascomycota and Basidiomycota, but the presence of several early diverging fungal subphyla thought to be primarily plant and litter associated, including Mortierellomycotina and Glomeromycotina (e.g., arbuscular mycorrhizal fungi), suggests a possible role as nematode egg parasites. Species richness varied by both crop rotation and season and was higher in early years of crop rotation and in fall at the end of the growing season. Crop rotation and season also impacted fungal community composition and identified several classes of fungi, including Eurotiomycetes, Sordariomycetes, and Orbiliomycetes (e.g., nematode trapping fungi), with higher relative abundance in early soybean rotations. The relative abundance of several genera was correlated with increasing years of soybean. Fungal communities also varied by season and were most divergent at midseason. The percentage of OTUs assigned to Mortierellomycotina_cls_Incertae_sedis and Sordariomycetes increased at midseason, while Orbiliomycetes

    We have studied MR images and the histopathology of eight patients with symptomatic Rathke's cleft cysts. Six cases showed visual disturbance and two showed galactorrhea. In five, the cyst fluid had low signal intensity on T1-weighted images and high intensity on T2-weighted images; in 2, the cyst fluid had high intensity on both T1- and T2-weighted images; in 1, the cyst fluid had high intensity on T1-weighted images and low intensity on T2-weighted images. Enhancement of the cyst wall by Gd-DTPA was able to be distinguished in 6 patients: 2 showed no enhancement, 2 showed thin enhancement and the remaining 2, thick enhancement. Fluid aspiration and total resection of the cyst wall was performed in all patients (3 by the transcranial approach and 5 by the transsphenoidal approach). Normal pituitary glands were found in all cases during the operations. Histopathologically, ciliated epithelium with goblet cells was recognized in 3. Non-ciliated epithelium was recognized in the other 5. Stratified squamous component was recognized in 1 and secondary inflammation, in another. Normal pituitary tissue was recognized in 5. Immunohistochemically, ciliated and non-ciliated epithelium was successfully stained for detecting antibody against epithelial membrane antigen and/or carcinoembryonic antigen. Two cases with no enhancement of the cyst wall by Gd-DTPA showed only ciliated epithelium. Two patients with thin enhancement of the cyst wall had single layer epithelium with normal pituitary tissue. Two patients with thick enhancement of the cyst wall showed single layer epithelium with its stratified squamous component or with secondary inflammation. A close relationship was suggested between the enhancement effect on MRI and histopathology of the cyst wall. (author)

    The aim of this study was to investigate the relative frequency of developmental odontogenic cysts in an Iranian population. In this study 245 cysts from both jaws, treated in the Faculty of Dentistry at Tabriz University of Medical Sciences during a 10-year period from 1998 to 2008, were analyzed in order to evaluate the incidence of such cysts. We had permission from all the patients. Case histories of 65% of male and 35% of female patients were analyzed. The age of the patients varied from 14 to 64 years, with an average of 33.21 ± 10.89. In this 10-year study of odontogenic cysts, 97 cases were developmental odontogenic cysts with the following inci-dence: dentigerous cyst, 44%; odontogenic keratocyst, 36%; primordial cyst, 9%; Gorlin cyst, 2%; lateral periodontal cyst, 3%; eruption cyst, 3%; and gingival cyst, 3% (adults 2%, infants 1%). A total of 60% of the cysts were found in the mandible and 40% in the maxilla. Regarding the mandible, the molar region was involved in 47% of the cases, premolar region in 33% and anterior region in 20% (total = 100%). Regarding the maxilla, the canine-to-canine region was involved in 52% of the cases, premolar region in 20% and molar region in 28% (total = 100%). An important finding in this study was the fact that 39% of the jaw cysts were developmental odontogenic cysts and the most common developmental odontogenic cysts were dentigerous cyst and OKC (odontogenic keratocyst).

    Limitation of morphological diagnostic and possible misinterpretations are shown in a patient with anamnestic ovarian endometriosis. In cases of "chocolate cysts" it is necessary to differentiate between ovarian endometriosis and functional cysts. Hints for the existence of a functional cyst are an atypical past history or perioperative findings. Biochemical analysis of the cyst fluid may lead to a correct diagnosis.

  19. INCIDENCE OF OVARIAN CYST IN HYPOTHYROIDISM: AN INSTITUTIONAL STUDY

    Full Text Available BACKGROUND Primary hypothyroidism is the decrease in production and secretion of thyroid hormones by the thyroid gland. This is characterised by slackening of metabolism and leading to multiple system impairment. The important aetiological factors for primary hypothyroidism are congenital, iodine deficiency, autoimmune thyroiditis and iatrogenic.[1] Ovarian cysts are a common cause for gynaecological surgeries. The aetiology[2] of ovarian cysts can vary greatly including benign or malignant tumours, endometriosis and inflammation, etc. However, some cysts are direct result of endocrine disorders and do not require surgery. Hypothyroidism may cause reproductive and endocrinological disorders as well. The aetiopathogenesis is complex. In 1960 Van Wyk and Grumbach first described the relation between ovarian cyst and hypothyroidism. They proposed that there was a hormonal overlap in the pituitary feedback mechanism. It is due to the fact that TSH, GH, FSH and LH are all glycoproteins with a common alpha chain and may thus cross react. High TSH could produce FSH and LH like activity leading to luteinised ovarian cyst. The TRH may also act on pituitary cells to stimulate gonadotropin release and hence FSH and LH. Other postulated mechanisms are increased ovarian sensitivity to gonadotropins, altered metabolism of oestrogen, hypothalamopituitary dysfunction and altered prolactin metabolism. AIMS To study the percentage of ovarian cyst among the diagnosed cases of primary hypothyroidism and then to find out the association between hypothyroidism and ovarian cyst. To study the relation between level of TSH and size of ovarian cyst. To study the percentage of ovarian cyst among patients with TSH 100 mIU/L separately. SETTINGS Study Design: Descriptive: Cross-sectional study. Duration: One year. Period: March 2013 to February 2014. Sample Size: 100. Study Area: Government Medical College, Calicut. INCLUSION CRITERIA Female patients of age more than 12

    Echography of the breast was performed in 100 women in whom palpation had prompted suspicion of the presence of a cyst. Examination was done with a real-time scanner with a 2.5 or 5 Mhz freely mobile soundhead. Cysts were detected in 56 women by this sonographic method. Approximately 9% of these were complicated cysts requiring surgical treatment. Although sonography facilitates identification of single or of multiple cysts, it will be necessary to perform pneumocystography and X-ray film examination in two projections on first examination in order to exclude complicated cysts, since mere sonographic control after puncture of the cysts is too inaccurate for identifying complicated cysts.
