    Mesenteric fibromatosis is an uncommon benign neoplasm occurring in the mesentery or retroperitoneum, and presenting as a firm mass with infiltrative margins and homogeneous parenchyma without necrosis or a cystic component (1-4). Cystic change may occur, usually after prolonged medical treatment, but is extremely rare (5-7). We describe the US and CT findings in a case of mesenteric fibromatosis with spontaneous extensive cystic degeneration.

    Full Text Available The calcifying odontogenic cyst was first reported by Gorlin et al . in 1962. It had been classified as a neoplasm related to the odontogenic apparatus because of its histological complexity and morphological diversity until it was renamed as a calcifying cystic odontogenic tumor by the WHO, in 2005. Here we describe a case of mandibular calcifying cystic odontogenic tumor in a 75-year-old male, which was present since five years, with a history of occurrence after the extraction of teeth in the involved region. The lesion was surgically removed and a histopathological examination revealed a cystic tumor with predominance of ghost cells and some amount of dentinoid tissue.

    Full Text Available We report a case of large primary mesenteric carcinoid tum or which was 7x7x4 cm. The 60 yr s old patient presented with the complaint of an abdominal mass since 1 yr. On radiology she was found to have a complex density mass surrounded by mesenteric fat with clear planes. On histopathology it was confirmed to be a carcinoid tumour of benign natur e. Primary mesenteric carcinoid tumor is very rare. 90% of them are found in GI tract with secondary involvement of mesentry in 40 - 80% cases when the size is larger than 2 cm. In this case it was a primary mesenteric tumour as there was no evidence of any o ther tumor. And second distant metastasis rate reported as 80% to 90% when they are larger than 2cm. The large size, primary mesenteric location and no metastasis despite large size make our case unique and rare.

    Full Text Available We present a case of a cystic adenomatoid tumor in a 40-year-old woman. The tumor was an intramural multicystic mass, histologically similar to a multicystic mesothelioma. Cystic adenomatoid tumors of the uterus are extremely rare. They present with a wide differential diagnosis in radiology. The tumors are known to be benign and awareness of this rare entity is the key to its diagnosis for a pathologist.

    Full Text Available Abstract Introduction Chylolymphatic mesenteric cysts are rare entities with variable presentations and this has surgical implications in the pediatric age group. Case presentation We carried out a retrospective analysis of the clinical and histopathological records of pediatric patients diagnosed and treated for chylolymphatic mesenteric cysts at our institute from 1998 to 2008. Eight patients met the histopathological criteria of chylolymphatic mesenteric cyst. These patients were in the age range 18 months to 10 years with a mean age of 4.5 years. Of these eight patients, four presented with an abdominal lump, and two each with abdominal pain and acute intestinal obstruction. On clinical examination, five out of the eight patients had a palpable abdominal mass. Laparotomy and complete excision of the cyst along with the involved gut was performed in all patients. There were no postoperative complications or any recurrence during the follow-up period which ranged from 4 months to 8 years. Conclusion Although very rare, chylolymphatic mesenteric cyst should be kept in mind as one of the differential diagnoses of cystic masses of the abdomen including cystic lymphangioma. Ultrasonography and computed tomography suggest the diagnosis but histopathological examination is required for confirmation. Complete excision of the cyst yields excellent results.

    Cystic partially differentiated nephroblastoma (CPDN) is a rare multicystic renal tumor along the spectrum of cystic nephroma and cystic Wilms' tumor. There have only been two previously reported cases of bilateral CPDN in the literature. We present here a case of bilateral CPDN vs cystic Wilms' tumor treated with neoadjuvant and adjuvant chemotherapy in addition to a bilateral partial nephrectomy. We also review the relevant literature regarding CPDN in an effort to aid in diagnosis and management of these rare cystic renal tumors.

    2016-01-01

    Although most cystic pancreatic lesions are pseudocysts, it is important to do a thorough differential diagnosis with true cystic tumors because cystic tumors are potentially malignant. Sometimes computed tomography and magnetic resonance imaging cannot establish the definitive diagnosis, making it necessary to perform other imaging tests such as endoscopic ultrasound, which in addition to morphological information, can also enable cytologic and biochemical analysis of the lesion through puncture and aspiration of its contents. Combining all these findings nearly always provides enough diagnostic information to allow the appropriate approach in each case. This article describes the specific morphological characteristics for each cystic pancreatic tumor on computed tomography, magnetic resonance imaging, and endoscopic ultrasound and reviews the guidelines for managing these types of lesions.

    Pancreatic pseudocysts are the most common cystic lesions of the pancreas and may complicate acute pancreatitis, chronic pancreatitis, or pancreatic trauma. While the majority of acute pseudocysts resolve spontaneously, few may require drainage. On the other hand, pancreatic cystic tumors, which usualy require extirpation, may disguise as pseudocysts. Hence, the distinction between the two entities is crucial for a successful outcome. We conducted this study to highlight the fundamental differences between pancreatic pseudocysts and cystic tumors so that relevant management plans can be devised. We reviewed the data of patients with pancreatic cystic lesions that underwent intervention between June 2007 and December 2010 in our hospital. We identified 9 patients (5 males and 4 females) with a median age of 40 years (range, 30-70 years). Five patients had pseudocysts, 2 had cystic tumors, and 2 had diseases of undetermined pathology. Pancreatic pseudocysts were treated by pseudocystogastrostomy in 2 cases and percutaneous drainage in 3 cases. One case recurred after percutaneous drainage and required pseudocystogastrostomy. The true pancreatic cysts were serous cystadenoma, which was treated by distal pancreatectomy, and mucinous cystadenocarcinoma, which was initialy treated by drainage, like a pseudocyst, and then by distal pancreatectomy when its true nature was revealed. We conclude that every effort should be exerted to distinguish between pancreatic pseudocysts and cystic tumors of the pancreas to avoid the serious misjudgement of draining rather than extirpating a pancreatic cystic tumor. Additionaly, percutaneous drainage of a pancreatic pseudocyst is a useful adjunct that may substitute for surgical drainage.

    Mesenteric cysts, seen in all age groups, represent a rare cause of benign abdominal masses in children. We reviewed 21 patients with mesenteric/omental cysts. Gross and radiologic images, along with histologic sections, were reviewed to categorize the structures and determine the relationship to the mesentery and intestines. The cysts were composed of multi-loculated dilated channels at the serosal surface consistent with lymphangioma. Most treatment was simple excision, infrequently with intestinal resection. Nineteen patients did well after surgery. One patient developed short-gut syndrome after massive bowel resection, and one patient died immediately after birth due to massive fetal hydrops and heart failure.

    Cystic PNETs are an uncommon neoplasms increasingly detected in current clinical practice which often present a diagnostic challenges to both the experienced radiologist and pathologist. The aim of this study was to review the available literature to summarize current data that compare and evaluate both the clinical and pathologic features of cystic pancreatic neuroendocrine tumors. A systematic review of the current literature was performed using the search engines EMBASE and PubMed to identify all studies reporting on cystic pancreatic neuroendocrine tumors. The MeSH search terms used were "cystic pancreatic neuroendocrine tumors", "endocrine neoplasms", and "pancreatic cysts". Multiple combinations of the keywords and MeSH terms were used. The clinical evaluation of cystic pancreatic lesions appears to suffer from same limitations despite the improvement in the diagnostic tools. Subsequently, we highlight diagnostic pitfalls and differential diagnosis of these cystic tumors. In this review we discuss current advances in the application of the imaging modalities and characteristics features with special emphasize on endoscopic ultrasound (EUS), and EUS guide fine needle aspiration (EUS-FNA). Cystic neuroendocrine tumor in the pancreas underlines the clinical impact of endoscopic ultrasound in the work-up of patients with unclear lesions in the pancreas. EUS-FNA cytology and cyst fluid analysis is a useful adjunct to abdominal imaging for the diagnosis of pancreatic cystic lesions. Due to the evident diagnostic difficulties, we hypothesize that cyst fluid characteristics, including cytomorphological features, is the most accurate test to achieve a preoperative diagnosis and to provide a basis for prognostic prediction.

    Background Hepatic artery variations are frequent clinical occurrences.The aim of this study was to investigate the characteristic course of variant hepatic arteries originating from the superior mesenteric artery for the purpose of providing instructions for abdominal tumor surgery.Methods The course of variant hepatic arteries originating from the superior mesenteric artery was studied in 400 patients with liver cancer confirmed by digital subtraction angiography (DSA) and multi-slice spiral computed tomography angiography (MSCTA),and 86 patients with gastric cancer confirmed by preoperative MSCTA between June 2008 and June 2010 in the First Affiliated Hospital of Guangxi Medical University.Results Hepatic artery variations originating from the superior mesenteric artery were noticed in 49 liver cancer patients and 14 gastric cancer patients (total 63 cases),with a variation rate of 12.96%,including two cases (3.17%) where the hepatic arteries ran along the anterior pancreas,and 61 cases (96.83%) where the hepatic arteries ran along the posterior pancreas.Conclusions Hepatic artery variations originating from the superior mesenteric artery present as two types:the pre-pancreas type and the post-pancreas type with the latter predominating.This finding is of clinical significance in abdominal tumor surgeries where clearance of portal lymph nodes is needed.

  16. Tyrosine Phosphorylation Modulates the Vascular Responses of Mesenteric Arteries from Human Colorectal Tumors

    Directory of Open Access Journals (Sweden)

    Eduardo Ferrero

    2013-01-01

    Full Text Available The aim of this study was to analyze whether tyrosine phosphorylation in tumoral arteries may modulate their vascular response. To do this, mesenteric arteries supplying blood flow to colorectal tumors or to normal intestine were obtained during surgery and prepared for isometric tension recording in an organ bath. Increasing tyrosine phosphorylation with the phosphatase inhibitor, sodium orthovanadate produced arterial contraction which was lower in tumoral than in control arteries, whereas it reduced the contraction to noradrenaline in tumoral but not in control arteries and reduced the relaxation to bradykinin in control but not in tumoral arteries. Protein expression of VEGF-A and of the VEGF receptor FLT1 was similar in control and tumoral arteries, but expression of the VEGF receptor KDR was increased in tumoral compared with control arteries. This suggests that tyrosine phosphorylation may produce inhibition of the contraction in tumoral mesenteric arteries, which may increase blood flow to the tumor when tyrosine phosphorylation is increased by stimulation of VEGF receptors.

    A 30-year-old man with familial adenomatous polyposis (FAP) underwent prophylactic proctocolectomy by laparoscopy-assisted surgery. After 10 months, we found an intra-abdominal tumor, which grew rapidly to 25 cm in diameter. We performed an emergency operation, which revealed that it was a desmoid tumor derived mainly from colorectal mesenterium. The tumor was removed with three short segments of intestine and the left ureter. A computed tomography (CT) scan done 3 months later showed a 10 cm mesenteric desmoid tumor at the beginning of jejunum, approaching the root of the superior mesenteric artery (SMA). Fortunately, we were able to remove the tumor without injuring the SMA. To our distress, however, another recurrent mesenteric desmoid tumor was discovered in the pelvis one month later, which grew rapidly from 5 cm to 16 cm within 4 months. During this period, we gave the patient several regimens, including antiestrogen (tamoxifen), a nonsteroidal anti-inflammtory drug and imatinib mesylate (Gleevec), which had little or no effect. Finally, when the desmoid occupied the pelvic space, we gave the patient dacarbazine (DTIC) and doxorubicin (DOX). After seven courses, the mesenteric tumor showed an almost complete response (CR). The chemotherapy caused grade 3 to 4 leukocytopenia, but without any hazardous events. No evidence of further recurrence of mesenteric desmoid has been seen for 4 years. This combination chemotherapy is a promising strategy, even against an extremely aggressive, life-threatening mesenteric desmoid associated with FAP.

    Biliary cyst tumors (cystadenoma and cystadenocarcinoma) are an indication for liver resection. They account for only 5% of all solitary cystic lesions of the liver, but differential diagnosis with multiloculated or complicated biliary cysts, atypical hemangiomas, hamartomas and lymphangiomas may be difficult. The most frequent challenge is to differentiate biliary cyst tumors from hemorrhagic cysts. Computerized tomography (CT) and magnetic resonance imaging (MRI) are often not diagnostic and in these cases fine needle aspiration (FNA) is used to confirm the presence of atypical biliary cells. FNA, however, lacks adequate sensitivity and specificity and should always be used in conjunction with imaging. Pre-operative differentiation of cystadenoma from cystadenocarcinoma is impossible and surgery must be performed if a biliary cyst tumor is suspected. When multiple cystic lesions are observed throughout the liver parenchyma, it is important to exclude liver metastasis, of which colonic cancer is the most common primary site. Multiple biliary hamartomas (von Meyenburg complex) can appear as a mixture of solid and cystic lesions and can be confused with cystic metastasis. Strong and uniform T2 hyperintensity on MRI is usually diagnostic, but occasionally a percutaneous biopsy may be required.

    The experience with percutaneous puncture of intraspinal cystic lesions is reported in cases: an extradural cyst demonstrated with air, a spinal cord tumor with lipiodol and two cases of syringomyelia with metrizamide. Percutaneous puncture of cystic lesions makes possible an accurate delineation of the lesion and a histological approach through biochemical and cytological analysis of the aspirated cystic fluid, while aspiration of the fluid of cystic tumors decompresses the spinal cord and thus plays a therapeutic role.

    Omental, mesenteric and retroperitoneal cystic masses are very rare in pediatric population. They usually present as asymptomatic abdominal tumors and only occasionally a preoperative diagnosis is made. We presented 4 cases presented to our hospital during a 2-year period. All patients were male with an age ranged from 5 months to 7 years. Three patients had previous diagnosis of cystic mass by abdominal ultrasound. Three patients presented with acute abdomen and one patient with bowel obstruction. All patients underwent successful resection of the mass with no perioperative mortality.

    This study is aimed at evaluating which pre-operative findings at CT are prevailingly associated with histologically malignant appearance of mucinous cystic tumor (MCT) of the pancreas. The CT examinations of 52 female patients affected with pathologically proved MCT were retrospectively evaluated by two radiologists, blinded to the histopathological assessment of the biologic behavior (either benign or malignant). A multivariate logistic regression analysis was performed in order to identify the most important features associated with the malignant nature of MCT. Calcifications in the wall and/or in the septa, thick wall, and septations resulted in the most important features associated with malignancy. The simultaneous presence of all these radiological signs constitutes an almost ''certain'' marker of malignancy, being the risk equal to 0.95, whereas the simultaneous presence of at least two of them entails a risk of malignancy ranging from 0.56 to 0.74, according to the type of morphological features. On the other hand, the absence of the mentioned radiological features entails a negligible risk of malignancy (0.02). Mucinous cystic tumors characterized by multilocular macrocystic architecture, with thick wall and calcifications in the wall and/or the septa, present the highest risk of malignancy, and advocate prompt surgical intervention. When those signs are absent, the probability of malignancy is lower. In this case a non-operative management is possible. (orig.)

    Odontogenic Calcificant Cystic Tumor (OCCT) is an infrequent injury. It arises from odontogenic epithelial rests present in the maxilla, jaw or gum. Gorlin and col. described the OCCT for first time as an own pathological entity in 1962. Clinically, the OCCT represents 1% of the odontogenic injuries. It is possible to be found from the first decade to the eighth decade. It affects in same proportion the maxilla and the jaw, being the most common in the dented zones, with greater incidence in the first molar area. Two case reports of OCCT in two different ages, both in female individuals, one at 5 years old and the other at 35 years old are presented. Enucleation of the tumor was the treatment chosen. The purpose of this article is to present a review of the literature related to these two cases of OCCT and its treatment, putting an emphasis on its aetiology, biological behaviour and treatment.

    Objective: The authors report an extremely unusual presentation and management of a children pineal mixed germ cell tumor mainly composed of immature teratoma, aiming to summarize main theraptic points by literature review. Methods: A cystic lesion located in the rear of third ventricle in a child was detected 3 years ago with no other therapy performed except for a ventriculo-peritoneal shunt. During the following 3 years, intermitted regular brain MRI demonstrated no evidence of lesion aggrandizement. However from 20 days before admission to our institute the patient began to present acutely with exacerbating clinical symptoms meanwhile brain MRI showed signs of abrupt revulsions of initial lesion without any incentive cause. Neurological examination revealed a significant rising of serum tumor marker level. Then surgical resection was performed immediately after admission which was followed by correlative two-course chemotherapy. Results: Postoperative brain MRI demonstrated totally removing of the lesion in rear of third ventricle. Serum tumor marker level decreased remarkably after surgery and declined to normal level after two-course chemotherapy. No obvious neurological deficit occurred except for short-term memory difficulty which gradually recovered within two weeks. Soon after the second course chemotherapy the patient was currently asymptomatic and returned to school. Conclusions: (1) To ensure definitive diagnosis and proper therapecutic protocols benefit from grasping clinical features of mixed germ cell tumor. (2) Overall preoperative investigation including serum tumor marker level is as critical as neurological imaging examination. (3) Surgical excision is confirmed to be the key modality of treatment. With the regarding of mixed germ cell tumor, never highlight total resection too much. (4) Postoperative adjuvant chemotherapy is recommended as further intensive treatment to improve the prognosis of mix germ cell tumor.

    Objective To estimate the clinical and pathological features of pancreatic solid cystic papillary tumor (SCPT) in children.Methods From 2000 to 2005 , 8 cases with SCPT of the pancreas were analyzed retrospectively. All cases but one were females. Average age was 12.8 years. By case review, we discussed the clinical and pathological features of SCPT in children.Results The chief complains were abdominal pain and palpable mass. There were 3 cases in the head, 1 case in the body, and 4 cases in the tail of pancreas. The procedures employed included local resection (1 case), distal pancre-atectomy (5 cases) , pancreaticoduodenectomy (1 case) , and biopsy (1 case). Histological examination showed solid with cystic areas and papillary protrusions in the 8 cases; as for immunohistochemical examinations, the positive rate was 100% for ct-antitrypsin (AACT) , 87.5% for vinmentin, and 62.5% for neuron-specific enolase (NSE). The patients were followed up for 2 months to 4 years but one was lost by follow-up and all were alive postoperatively. SCPT in 2 cases relapsed.Conclusion Occurring predominantly in young females, SCPT is usually curable by surgical resection with a favorable prognosis.

    The aim of the authors is to introduce one rare known pathology which the Frantz's tumor is, his clinical characteristic, clinical signs, diagnostic and treatment. We have observed two separate cases of this illness in Clinic of Surgery (University Hospital "Queen Yoanna") in comparison with evidence of famous world surgeons. We have made an attempt to introduce one disease, which even though not often observed is significant by the fact that affect young women (girls) and only surgical resection is a treatment of choice.

  7. Cystic tumors of the pancreas: Opportunities and risks

    Pancreatic cystic neoplasms(PCNs) are a high prevalence disease. It is estimated that about 20% of the general population is affected by PCNs. Some of those lesions can progress till cancer, while others behave in a benign fashion. In particular intraductal papillary mucinousneoplasms of the pancreas can be considered as the pancreatic analogon to colonic polyps. Treatment of these precursor lesions at an early stage can potentially reduce pancreas cancer mortality and introduce a new "era" of preemptive pancreatic surgery. However, only few of those lesions have an aggressive behavior. The accuracy of preoperative diagnosis, i.e., the distinction between the various PCNs is around 60%, and the ability to predict the future outcome is also less accurate. For this reason, a significant number of patients are currently over-treated with an unnecessary, high-risk surgery. Furthermore, the majority of patients with PCN are on life-long follow-up with imaging modality, which has huge cost implications for the Health Care System for limited benefits considering that a significant proportion of PCNs are or behave like benign lesions. The current guidelines for the diagnosis and management of PCNs are more based on expert opinion than on evidence. For all those reasons, the management of cystic tumors of the pancreas remains a controversial area of pancreatology. On one hand, the detection of PCNs and the surgical treatment of pre-cancerous neoplasms can be considered a big opportunity to reduce pancreatic cancer related mortality. On the other hand, PCNs are associated with a considerable risk of under- or over- treatment of patients and incur high costs for the Health Care System.

    Pancreatic cystic tumours are rare and less frequent than other pancreatic tumours. In recent decades, these tumours are being diagnosed with increasing frequency due to the extensive availability of, and improvement in, modern imaging techniques and it is often possible not only to differentiate them preoperatively from other cystic pancreatic disorders but also from one another. Pancreatic cystic tumours comprise a variety of neoplasms with a wide range of malignant potential: serous cystic tumours are benign, whereas mucinous cystic tumours, and intraductal papillary mucinous tumours are considered premalignant, while solid pseudopapillary tumours have a non-aggressive behaviour in the vast majority of cases. Most patients have no symptoms; and when clinical signs are present, they never help us to identify the type of pathology. Serous cystic neoplasms usually do not mandate resection unless the lesion is symptomatic. Mucinous cystic neoplasms and intraductal papillary mucinous neoplasms have a premalignant or malignant tendency, and therefore need to be managed aggressively by pancreatic resection. Their prognosis is excellent in the absence of invasive disease, but the presence of invasive malignancy is associated with a poor prognosis. This review addresses the symptoms, diagnosis, management and prognosis of this group of tumours.

    Mesenteric fibromatosis is a rare benign fibroblastic tumor; moreover, cases that occur in the mesocolon are even rarer. In some cases, mesenteric fibromatosis is difficult to differentiate from a malignant tumor that shows an infiltrative growth pattern or forms intussusception similar to lymphoma or adenocarcinoma. In this study, we reported a case of mesenteric fibromatosis represented as a colo-colic type intussusception adjacent to the ascending colon mimicking malignant tumors such as lymphoma or adenocarcinoma.

    To describe the computed tomography (CT) features of neuroendocrine tumors (NETs) and solid pseudopapillary tumors (SPTs) with unilocular cyst-like appearance, and to compare them with those of unilocular cystic tumors of the pancreas. This retrospective study was approved by our Institutional Review Board, and informed consent was waived. We included 112 pancreatic tumors with unilocular cyst-like appearance on CT (16 solid tumors [nine NETs and seven SPTs] and 96 cystic tumors [45 serous cystadenomas, 30 mucinous cystic neoplasms, and 21 branch-duct intraductal papillary mucinous neoplasms]). Two radiologists reviewed the CT images in consensus to determine tumor location, long diameter, morphological features, wall thicknesses, ratio of wall thickness to tumor size, wall enhancement patterns, intratumoral contents, and accompanying findings. Fisher's exact test was used to analyze the results. All 16 solid tumors had perceptible walls (mean thickness, 2.7 mm; mean ratio of wall thickness to tumor size, 7.7%) with variable enhancement. Four NETs and seven SPTs had hemorrhage, calcifications, and/or mural nodules. Six CT findings were specific for solid tumors with unilocular cyst-like appearance: a thick (> 2 mm) wall, uneven thickness of the wall, high ratio of wall thickness to tumor size, hyper- or hypo-attenuation of the wall in the arterial and portal phase, and heterogeneous internal contents. When three or more of the above criteria were used, 100% specificity and 87.5-92% accuracy were obtained for solid tumors with unilocular cyst-like appearance. A combination of CT features was useful for distinguishing solid tumors with unilocular cyst-like appearance from unilocular cystic tumors of the pancreas.

    Full Text Available Cystic fibrohistiocytic tumor of the lung is a rare neoplasm. In many cases it represents a metastasis from a benign or low-grade fibrohistiocytic tumor of the skin, but occasionally it may be primary. Radiologically it usually occurs as a cystic change of multiple pulmonary nodules, and pneumothorax is the most frequent presenting symptom. We present here a 16-year-old man with recurrent right pneumothorax. The patient had no his-tory of cutaneous fibrohistiocytic lesions. He underwent videothoracoscopic right apical segmentectomy, right lower lobe nodulectomy, and pleuroabrasion. Microscopy of the apical segmentectomy showed a cystic fibrohistio-cytic tumor, whereas the nodule of the lower lobe was an intraparenchymal lymph node. The patient is alive with no tumor recurrence. The differential diagnosis includes Langerhans cell histiocytosis, lymphangioleiomyomatosis, pleuropulmonary blastoma, and metastatic endometrial stromal sarcoma. This disease usually occurs with multiple pulmonary cysts and cavitation. This case is the first reported presenting as a single lesion.

    Full Text Available The authors report the case of a 37 year-old man with a solitary cysticercus cyst in the brainstem (pons successfully removed through a suboccipital craniectomy. Surgery in neurocysticercosis has been indicated in patients with hydrocephalus and/or large cystic lesions. Cystic lesions in the brainstem and spinal cord may have indication for surgery for two reasons: (1 diagnosis; and (2 treatment. Aspects related to differential diagnosis and therapeutic alternatives are discussed.

    In the present case, we report the association of multiple ileal neuroendocrine tumors and idiopathic myointimal hyperplasia of the mesenteric veins, 2 rare conditions that could have an etiopathogenetic relationship. Idiopathic myointimal hyperplasia of mesenteric veins implies a near-total obliteration of venular vessels, which can lead to hypoxic disorders. Hypoxia in tumors is associated with increased metastatic potential and resistance to radiotherapy and chemotherapy. Herein we speculated on the existence of a relationship between hypoxia and multiple location of neuroendocrine tumors. © The Author(s) 2016.

  14. Primary ovarian neuroendocrine tumor arising in association with a mature cystic teratoma: A case report

    Full Text Available Primary ovarian carcinoid tumors are exceptionally rare entities accounting for approximately 0.1% of all ovarian neoplasms. This report describes a primary ovarian neuroendocrine tumor arising in association with a mature cystic teratoma in a 65 year-old woman. Macroscopically, the unilateral adnexal tumor was composed of cystic, solid and mucinous elements which resolved into a dual component lesion histologically. The majority of the tumor displayed an organoid architecture with mild to moderate pleomorphism and no discernible mitotic activity, while approximately 10% consisted of sheets and groups of cells with highly pleomorphic nuclei, necrosis and occasional mitoses. Features of a mature cystic teratoma were seen very focally. Immunohistochemistry revealed strong, diffuse positivity for CD56 and synaptophysin. Chromogranin immunonegativity was noted and there was an absence of nuclear β-catenin accumulation. Ki-67 index was 10–12%. Although there is no established diagnostic framework for primary ovarian carcinoid tumors, this case was diagnosed as a well-differentiated neuroendocrine tumor, Grade 2 (intermediate grade, arising in association with a mature cystic teratoma/dermoid cyst. This case highlights the need to develop ovarian diagnostic criteria in this area.

    Eight cases of spontaneous isolated mesenteric fibromatosis (SIMF) were retrospectively reviewed. Clinical presentations included palpable abdominal mass (n = 6), abdominal pain (n = 4), gastrointestinal bleeding (n = 2) and acute abdomen (n = 1). On sonography and computed tomography (CT), eight SIMFs (size range 3 to 24 cm, mean 14.8 cm) were categorized into four morphologic patterns: well-defined inhomogeneous, well-defined homogeneous, well-defined cystic or infiltrative mesenteric mass patterns. Well-defined inhomogeneous SIMF (n = 3) was correlated with the histopathologic finding of bundles of fibroblasts with unevenly intermingled hyaline and/or myxoid degeneration areas, whereas well-defined homogeneous SIMF (n = 2) showed scarce degenerative changes. Well-defined cystic SIMF (n = 2) were ascribed to the presence of large areas of myxoid and cystic degenerations. One SIMF presented as an infiltrative mesenteric mass and the patient died 10 months after diagnosis. Both cases of cystic SIMFs showed tumor recurrences and one patient died after 84 months. The other five patients were cured by radical tumor resection. In summary, sonography, similar to CT, is also useful for evaluating SIMF with protean morphologic features, ascribing to the underlying histopathologic changes with varied degrees of hyaline, myxoid or cystic degenerations.

    Gastric adenomyoma is a rare benign subepithelial tumor, characteristically composed of mucosal structures and a prominent smooth muscle stroma. Because of rarity and the nonspecific computed tomography (CT) features, it is difficult to diagnose gastric adenomyoma before operation. In our case, gastric adenomyoma showed a well-circumscribed cystic subepithelial mass with uneven wall thickness on a CT scan, similar to the findings of former reports. The radiologic differential diagnosis can be narrowed down to several diseases, including duplication cysts, gastritis cystica profunda, brunner's gland hyperplasia and solid tumors with cystic degeneration. Also, adenomyoma could be included in the differential diagnosis of gastric cystic subepithelial masses, especially in the distal part of the stomach.

    The purpose of this study was to evaluate the differential radiologic findings of pure mucocele-like tumor and mucocele-like tumor associated with atypical ductal hyperplasia (ADH) or malignancy of the breast according to BI-RADS and sonographic cystic mass classification. During a 10-year period, 72 mucocele-like tumors in 68 women were diagnosed histologically at three institutions. We retrospectively reviewed the mammographic (n = 69) and ultrasound (n = 72) findings of the 72 lesions according to the BI-RADS lexicon. The radiologic findings were correlated with the pathologic results. Mammography showed 53 lesions had calcifications without (n = 39) or with (n = 14) a mass. Calcifications of intermediate concern or associated with higher probability of malignancy were found more frequently in mucocele-like tumors associated with ADH or malignancy than in pure mucocele-like tumors (92.3% vs 62.9%, p = 0.019). At ultrasound, 69 of the mucocele-like tumors (95.8%) were seen as a cystic mass. Cysts with thick septations, clustered cysts, and complex masses were more frequently seen in mucocele-like tumors associated with ADH or malignancy (89.7% vs 32.5%, p Mucocele-like tumors associated with ADH or malignancy were more frequently seen as clustered cysts, cysts with thick septations, and complex masses associated with calcifications of intermediate concern or higher probability of malignancy. BI-RADS can be used in the management of mucocele-like tumors.

  19. Conservative approach to recurrent calcifying cystic odontogenic tumor occupying the maxillary sinus: a case report

    Science.gov (United States)

    2016-01-01

    Calcifying cystic odontogenic tumor (CCOT) is an uncommon benign cystic neoplasm of the jaw that develops from the odontogenic epithelium. Invasion into the maxillary sinus by a CCOT is not a typical, and the recurrence of the cystic variant of CCOT in the posterior maxilla is rare. This report describes a recurrent CCOT occupying most of the maxillary sinus of a 24-year-old male patient. As a treatment, marsupialization was carried out as a means of decompression, and the involved teeth were all endodontically treated. Afterward, surgical enucleation was performed. The size of the lesion continued to shrink after marsupialization, and the maxillary sinus restored its volume. This patient has been followed-up for 3 years after the surgery, and there have not been any signs of recurrence. PMID:27847742

    Primary cystic tumors of papillary muscles of the heart are extremely rare. Here, one case of unusual cystic tumor in papillary muscle of the heart in a 37-year-old Myanmar migrant worker has been reported. He came to Malaysia 2 weeks before and one morning was found dead in sleep. Autopsy revealed cystic lesion in the papillary muscle of the mitral valve of heart, which was prolapsing into ventricular cavity. The cyst had white-jelly like sticky mucus material. The cyst was present in papillary muscle with slight invasion in septum area; it was lined by cuboidal-columnar epithelium and contained mucinous contents. There was no evidence of an inflammatory reaction in the cyst and in cardiac muscles. In addition to cystic neoplasm, the deceased also had histoplasmosis of the lungs. The case is presented with macroscopic and microscopic photographs of the cyst and histoplasmosis of the lungs. This case is reported because of its rarity, unique position, and unusual appearance.

    Pancreatic endocrine tumors (PETs) or islet cell tumors are rare lesions, the incidence of which is estimated to be less than 1 per 100,000 person-years in the general population. PETs can be divided into functional (exhibit a distinct clinical syndrome due to hormone hypersecretion) and non-functional tumors. The majority of PETs are non-functional. In spite of their rarity, cystic neoplasms of the pancreas are characterized by existing or potential malignancy that cannot be ignored during decisive process with regard to the choice of treatment. The purpose of this workis to find an association with Crohn's disease and cystic degeneration of a neuroendocrine tumor of the pancreas. Crohn's disease may affect extraintestinal organs, including the pancreas. In such cases, It seems certain that many patients diagnosed with Crohn disease (CD) are predisposed to a wider spectrum of cancers. We present a case of pancreatic cyst with no typical features of pseudocyst in the medical interview, with history of Crohn's disease, treated by caudal pancreatectomy. We tried to evaluate the clinical and morphological features of so-called cystic neoplasms associated with inflammatory bowel disease and to define their pathological characteristics.

    Solitary fibrous tumor (SFT) is a benign mesenchymal neoplasm of a spindle-cell origin, and it usually involves the pleura. It's occurrence in various organs of the body has recently been described. Meningeal SFT is very rare. Radiologically, it is a strongly enhancing solid mass and is undistinguishable from fibrous meningioma and hemangiopericytoma. Yet we report here on a case of SFT with massive cystic degeneration that arose from the meninges of the left occipital region.

    2013-11-28

    The authors report on a case of benign myolipoma (synonym lipoleiomyoma) which was first described in 1991. The benign soft tissue tumor is composed of smooth muscle and adipose tissue and occurs sporadically in different locations. In the available literature cases were described retroperitoneal, spinal, orbital and subcutaneous and mostly have been discovered in females. Characteristically myolipomas are very large at diagnosis and reach diameters of 7 to 30 cm particularly in peritoneal or retroperitoneal localization. The sometimes enormous size leads to a displacing growth pattern which ultimately leads to the clinical symptoms. The patients often complain of nonspecific, mostly painless abdominal or thoracic pressure. Bordered by an intact capsule the tumors show no signs of malignancy and in the available literature there is no evidence of metastatic seeding. To the best of our knowledge the presented case is the first description of a diffuse mesenteric myolipoma in a male individual. In this article, we present the multidetector computed tomographic image characteristics, macroscopic appearance and histopathological findings.

    Skeletal changes leading to a suspicion of the presence of a tumour frequently occur in childhood with the roentgenological manifestation of a cyst. X-ray morphology can differ depending upon the localisation and the course. In childhood, however such findings are mainly classified as tumour-like bone lesions. This group comprises, inter alia, the juvenile bone cyst, the aneurysmatic bone cyst and fibrous dysplasia. However, it is necessary to exclude by differential diagnosis - even though the main age of manifestation is after completion of growth - genuine bone tumours with cystic phenomena, such as the giant cell tumour, chondroma or chondroblastoma. Verification of the diagnosis can be effected via radiologic-diagnostic methods such as tomography and angiography as well as computerized tomography. The use of scintigraphy of the skeleton can likewise be indicated. Numerous laboratory parameters can be used in individual cases to exclude certain diagnoses. Taking these aspects into consideration, the article reviews differential diagnosis of the most frequent skeletal affections in childhood. Great emphasis is given to the ranking and importance of the individual diagnostic methods.

    Objective To evaluate imaging features of the serous cystadenomas and mucinous cystic tumors of the pancreas.Methods The imaging findings in 59 patients with pathologically proven serous cystadenomas (SCs), mucinous cystadenomas (MCs), and mucinous cystadenocarcinomas (MCCs) of the pancreas were reviewed for location, thickness of septa or the cyst wall, number of cysts, diameter of the largest cyst, lesion calcification, presence of mural node or solid enhancing component, dilatation of the main pancreatic duct (MPD), lesion communication with MPD, invasion of surrounding organs, and regional lymphadenopathy.Results The characteristic imaging feature of SCs was that of microcystic lesion with >6 cysts, the diameter of the largest cyst being <2cm. Mucinous cystic tumors (MCTs) including MCs and MCCs were that of macrocystic lesion with <6 cysts, the diameter of the largest cyst being >2 cm. MCs was that of a lesion with smooth and regular cyst wall and septa, the wall/septa thickness being <0.3 cm. MCCs was that of a cystic lesion with thick irregular septa, presence of mural node or solid enhancing component, invasion of surrounding structures. These findings were of statistical significance.Conclusion SCs, MCs, and MCCs have characteristic imaging features. Analysis of the number of cysts, septation features, mural node or solid enhancing component, diameter of the largest cyst, dilatation of the pancreatic duct, and invasion of surrounding structures often can successfully subtype tumors into benign SCs or potentially malignant MCs or malignant MCCs.

    The purpose of this study was to assess the efficacy of image-guided radiofrequency (RF) ablation of cystic renal tumors. Between November 2005 and August 2007, computed tomography (CT) or ultrasound-guided RF ablation was performed in nine patients with 14 Bosniak category III (n = 5) or IV (n = 9) cystic renal tumors using an internally cooled RF ablation system. We evaluated the number of sessions, cycles and duration of energy application, treatment results, lesion size change, and complications. Together the cystic renal tumors required 15 sessions and 23 cycles of energy application. The duration of energy application per one tumor ablation ranged from 1 to 12 min (mean 6 min). The last follow-up CT indicated complete coagulation of 14/14 (100%) lesions. None of these tumors had recurred within 1-19 months (mean 8 months). The maximum diameter of the cystic renal tumors was significantly reduced from 2.5 {+-} 0.6 cm before ablation to 1.7 {+-} 0.7 cm at the last follow-up CT (P < 0.01). Complications were pneumothorax (n = 2), inguinal paresthesia (n = 1), and arteriovenous fistula (n = 1). Image-guided RF ablation is an effective treatment for Bosniak category III or IV cystic renal tumors, which might need relatively shorter duration of energy application than purely solid renal tumors of the same size.

    Full Text Available Solid and cystic tumor (SCT of the pancreas predominantly Occurs in women, and the occurrence in men is extremely rare. We experienced a male case of SCT. A 38-year-old man was admitted with the complaint of upper abdominal pain. CT scan showed the presence of a mass in the head of the pancreas. The mass was composed of high density areas and low density areas. Ultrasonograms revealed the mass being composed of high echoic areas and low echoic areas. The mass .was hypovascular on angiography. SCT was suspected and pancreaticoduodenectomy was performed. The cut surface of the tumor showed mainly cystic degenerative areas containing dark red hemorrhagic materials. Microscopically, there were solid areas in the periphery and pseudopapillary areas in the center. No metastasis was found in the removed lymph nodes. The tumor cells were not stained by Grimelius' silver stain. The tumor cells were positive for alpha-l-antitrypsin (AAT and neuron-specific enolase (NSE. Pancreatic hormones such as insulin, glucagon, and somatostatin were all negative. Electron micrograph showed that tumor cells were rich in mitochondria. Zymogen granules and neurosecretory granules were not detected. Estrogen receptor (ER and progesterone receptor (PR were both negative.

    Ovarian cystic tumors with a mural nodule are a rare entity. We report a case of a mural nodule of anaplastic spindle cell carcinoma in an ovarian mucinous cystic tumor of borderline malignancy. The patient was a 45-years-old Japanese woman who presented with an ovarian cyst. She suffered from mature cystic teratoma of both ovaries 9 years before the present history. Image analysis and laboratory data showing a high serum CA19-9 level suggested ovarian malignancy. She underwent bilateral salpingo-oophorectomy with hysterectomy and omentectomy. There was a mural nodule in the ovarian mucinous cystic lesion. Microscopically, the nodule was composed of spindle-shaped cells with severe nuclear atypia. Immunohistochemical analysis allowed the cells to be categorized as anaplastic spindle cell carcinoma. Fifteen months after the operation the patient is alive without any clinical findings of tumor recurrence. To the best of our knowledge in the English literature, this is the first report of a mural nodule of an anaplastic spindle cell carcinoma within an ovarian mucinous cystic borderline tumor harboring previously confirmed cystic teratoma.

  10. Cone Beam Computed Tomography Findings in Calcifying Cystic Odontogenic Tumor Associated with Odontome: A Case Report

    2015-12-01

    Full Text Available The calcifying cystic odontogenic tumor (CCOT is a rare cystic odontogenic neoplasm frequently found in association with odontome. This report documents a case of CCOT associated with an odontome arising in the anterior maxilla in a 28-year-old man. Conventional radiographs showed internal calcification within the lesion but were unable to visualize its relation with the adjacent structures and its accurate extent. In this case cone beam computed tomography (CBCT could accurately reveal the extent and the internal structure of the lesion which aided the presumptive diagnosis of the lesion as CCOT. This advanced imaging technique proved to be extremely useful in the radiographic assessment and management of this neoplasm of the maxilla.

    2016-07-01

    Full Text Available A mesenteric cyst is defined as a cyst that is located in the mesentery of the gastrointestinal tract and may extend from the base of the mesentery into the retroperitoneum. A case report of a patient with mesenteric cyst is presented. In addition, a systematic review was performed of English language literature on chylous mesenteric cysts in adult humans. Of the 18 articles included in the review, there were 19 cases of chylous mesenteric cysts reported. Male to female ratio was 1.4:1 with a median age of 46 years. A preoperative diagnosis of mesenteric cyst was made in four patients based on computed tomography. All patients underwent surgery and there were no reports of recurrence on follow up. Chylous mesenteric cyst is a rare entity that needs to be recognized whenever a preliminary diagnosis of intra-abdominal cystic mass is made.

  12. Hypercalcemia Associated with a Malignant Brenner Tumor Arising from a Mature Cystic Teratoma

    Directory of Open Access Journals (Sweden)

    Michael C. Honigberg

    2012-11-01

    Full Text Available A 60-year-old woman presented with abdominal pain and weight loss and was found to have serum calcium of 15.0 mg/dl. Serum parathyroid hormone-related peptide (PTHrP returned elevated. Imaging suggested bilateral mature cystic teratomas. Her hypercalcemia was treated initially with intravenous saline, as well as intramuscular and subcutaneous calcitonin. She underwent total abdominal hysterectomy with bilateral salpingo-oophorectomy, and final pathology revealed malignant Brenner tumor in association with a mature cystic teratoma. Her postoperative PTHrP returned less than assay, and her total and ionized calcium fell below normal, requiring supplemental calcium and vitamin D. At follow-up one month after discharge, her calcium had normalized. We present the first reported case of hypercalcemia occurring in association with a malignant Brenner tumor. Malignancy-associated hypercalcemia occurs via four principal mechanisms: (1 tumor production of PTHrP; (2 osteolytic bone involvement by primary tumor or metastasis; (3 ectopic activation of vitamin D to 1,25-(OH2 vitamin D, and (4 ectopic production of parathyroid hormone. PTHrP-mediated hypercalcemia is the most common mechanism and was responsible in this case. In patients with paraneoplastic hypercalcemia who undergo surgical treatment, close monitoring and management of serum calcium is necessary both pre- and postoperatively.

    The purpose of this study was to investigate the usefulness of computerized tomography (CT), particularly contrast-enhanced CT, in differentiation of jaw cysts and cystic-appearing tumors. We retrospectively analyzed contrast-enhanced CT images of 90 patients with odontogenic jaw cysts or cystic-appearing tumors. The lesion size and CT values were measured and the short axis to long axis (S/L) ratio, contrast enhancement (CE) ratio, and standard deviation ratio were calculated. The lesion size and the S/L ratio of keratocystic odontogenic tumors were significantly different from those of radicular cysts and follicular cysts. There were no significant differences in the CE ratio among the lesions. Multidetector CT provided diagnostic information about the size of odontogenic cysts and cystic-appearing tumors of the jaws that was related to the lesion type, but showed no relation between CE ratio and the type of these lesions.

    The purpose of this study was to assess computed tomography (CT) and magnetic resonance (MR) imaging findings of salivary gland tumors of the parotid gland with emphasis on intratumoral cystic components. Seventy-two histopathologically confirmed salivary gland tumors of the parotid gland (44 benign and 28 malignant), which underwent both CT and MR imaging including contrast-enhanced study, were included in this study. We retrospectively reviewed images for the presence, number, occupying rate, margin characteristics, distribution, and predominant MR signal intensity of intratumoral cystic components. The prevalence of cystic components was greater in malignant than benign tumors (79 vs. 50 %, p < 0.05). The number and occupying rate were similar between benign and malignant tumors. The irregular margins were more frequent in malignant than benign tumors (73 vs. 27 %, p < 0.01). The frequency of eccentric location was greater in benign than malignant tumors (91 vs. 55 %, p < 0.01), whereas the frequency of centric location was greater in malignant than benign tumors (32 vs. 0 %, p < 0.01). On T1-weighted images, the frequency of hyperintensity was greater in benign than malignant tumors (50 vs. 9 %, p < 0.01), whereas that of isointensity was greater in malignant than benign tumors (50 vs. 0 %, p < 0.01). Multiple logistic regression analysis showed that the absence of irregular margins of cystic components only was significantly correlated with the presence of benign salivary gland tumors (p < 0.01). Imaging features of intratumoral cystic components may help to differentiate benign from malignant tumors of the parotid salivary gland. (orig.)

    Full Text Available Calcifying cystic odontogenic tumor (CCOT demonstrates considerable diversity in histopathology and clinical behavior. Ghost cell odontogenic carcinoma (GCOC is the rare malignant counterpart of CCOT and it frequently arises from malignant transformation of a recurrent CCOT. In this paper, we present a case of CCOT and discuss its distinct histopathologic features in recurrence. Then, we will have a review on clinical, histopathological, and immunohistochemical aspects of GCOC in the literature. Predictive factors of malignant transformation in a benign CCOT will also be discussed.

    Full Text Available Ovarian and paraovarian neoplasms are uncommon in children, mainly originating from germ cell tumors and, least frequently, epithelial tumors. There is an association between genital tract tumors and Proteus syndrome, a rare, sporadic, and progressive entity, characterized by a postnatal overgrowth in several tissues caused by a mosaic mutation in the AKT1 gene. We describe a 20-month-old asymptomatic infant with Proteus syndrome who developed an endometrioid paraovarian borderline cystic tumor. This is the youngest patient so far reported in the literature with this rare syndrome and an adnexal tumor of borderline malignancy. A total of nine patients have been described with female tract tumors and associated Proteus syndrome, which includes bilateral ovarian cystadenomas and other benign masses. A paraovarian neoplasm is extremely rare in children and could be considered a criterion for Proteus syndrome. Standardized staging and treatment of these tumors are not well established; however, most authors conclude that these neoplasms must be treated as their ovarian counterparts.

    Full Text Available Abstract Background Pigmented intraosseous odontogenic lesions are rare with only 47 reported cases in the English literature. Among them, pigmented calcifying cystic odontogenic tumor, formerly known as calcifying odontogenic cyst, is the most common lesion with 20 reported cases. Methods A case of pigmented calcifying cystic odontogenic tumor associated with odontoma occurring at the mandibular canine-premolar region of a young Japanese boy is presented with radiographic, and histological findings. Special staining, electron microscopic study and immunohistochemical staining were also done to characterize the pigmentation. Results The pigments in the lesion were confirmed to be melanin by Masson-Fontana staining and by transmission electron microscopy. The presence of dendritic melanocytes within the lesion was also demonstrated by S-100 immunostaining. Conclusion The present case report of pigmented calcifying cystic odontogenic tumor associated with odontoma features a comprehensive study on melanin and melanocytes, including histochemical, immunohistochemical and transmission electron microscopic findings.

    Full Text Available Calcifying cystic odontogenic tumor (CCOT is an extremely rare clinical entity. It was considered as a cyst until 2005, when World Health Organization included it among the odontogenic tumors. It presents as a slow-growing, painless swelling of the jaw. Radiographically, it may be seen as a unilocular or multilocular radiolucency. Here, we present a case of a proliferative ameloblastomatous type of CCOT of the left mandible. Conventional radiography and cone beam computed tomography were performed, in which the lesion was found to be unicystic without any sign of calcification. The lesion was also associated with an impacted 37 tooth, which was displaced to the inferior border of the mandible.

    Hybrid tumor composed of epidermal cyst and pilomatricoma has been reported in only four times in the English literature. Herein, a cutaneous hybrid tumor composed of epidermal cyst and cystic pilomatricoma in a 58-year-old woman was presented. The tumor was located in the scalp, and measured 1 x 1 x 1 cm. The tumor was cystic and contained atheromatous materials. Histologically, the cyst was composed of epidermal cyst (50% in area) and pilomatricoma (50% in area). The pilomatricoma was composed mostly of basophilic cells. Interestingly, the pilomatricoma element of the cyst showed immunoreactive p53 and Ki-67 (labeling=40%). In conclusion, the fifth case of hybrid tumor composed of epidermal cyst and pilomatricoma was presented.

    Background Wnt/β-catenin signaling pathway is essential for the beginning of odontogenesis and may be involved in the development and progression of some odontogenic tumors. Thus, the aim of this study was to comparatively evaluate the immunohistochemical expression of Wnt/β-catenin signaling pathway proteins in a series of AME and CCOT. Material and Methods Immunohistochemical reactions were performed using antibodies against Wnt1, Wnt5a and β-catenin in 17 cases of solid AME and 6 cases of CCOT. Results In the AME group, Wnt1 and Wnt5a were identified in the epithelium in most of the cases, and β-catenin was mainly identified in the cytoplasm of the tumoral cells. In the CCOT group, Wnt1 and Wnt5a were identified in the epithelium and in the ghost cells in almost all the cases, and β-catenin was mainly identified in the cytoplasm and in the nuclei of the tumoral cells. Conclusions These results contribute to support the importance of Wnt/β-catenin signaling pathway proteins in AME and CCOT tumorigenesis. The abnormal expression of cytoplasmic and/or nuclear β-catenin appears to contribute to the development of both AME and CCOT. In addition, it is possible that Wnt1 and Wnt5a expression in ghost cells can contribute to its histogenesis in CCOT. Key words:Ameloblastoma, β-catenin, calcifying cystic odontogenic tumor, immunohistochemistry, Wnt. PMID:28149478

    We report the use of CT-guided stereotaxic system to implant Ommaya reservoir in 26 patients with cystic brain tumors consisting of 16 gliomas, 3 craniopharyngiomas, 3 metastatic brain tumors and 5 other and unknown pathologies, on the way of their biopsy. The entire procedure was carried out in the CT room using Leksell's CT stereotaxic system. In 24 cases with supratentorial tumors, it was at the option of the operator to take any approach such as frontal, posterior temporal and parietal approaches. Especially in 3 cases of craniopharyngioma, we inserted the tube into their cyst directly so that the ventricle should not be open to the cyst. Also in cases of a pontine glioma and a C-P angle metastatic tumor, we used retromastoid approach to the posterior fossa by making patient's heads turned about 30 to 40 deg to contralateral side of the approach, with slight flexion of the neck. Minimal bleeding occurred during operation in one case, however, it showed no clinical symptoms. Advantages of this method are as follows: Operative invasion is minimal; The surgeon can check the course of the cannula and position of the tip of Ommaya tube even at operation, and can modify it, if necessary.

    Cystic lesions of the pancreas can be either inflammatory (pseudocyst) or neoplastic. Neoplastic cysts contain either serous or mucinous fluid. Mucinous cystic tumor are more common in the tail of the pancreas of young women with palpable upper abdominal mass. The treatment is total excision of the lesion, and has very good results. The authors report the case of a 41-year-old woman, who presented a large palpable upper abdominal mass and fever. Abdominal sonography and CT scan have shown a heterogeneous cyst in the pancreas body and tail. The histologic diagnosis was mucinous cystic tumor of the pancreas. The treatment was removal of the body and tail of the pancreas together with the cyst. One year after surgery, the patient is doing well. (author) 18 refs., 2 figs.

    Lower female genital tract tumors with adenoid cystic differentiation are rare, and data on their relationship with high-risk human papillomavirus (HPV) are limited. Here we report the clinicopathologic features from a case series. Tumors with adenoid cystic differentiation, either pure or as part of a carcinoma with mixed differentiation, arising in the lower female genital tract were evaluated by means of immunohistochemical analysis for p16 expression and in situ hybridization using 1 or more probes for high-risk HPV (a high-risk probe covering multiple types, a wide-spectrum probe, and separate type-specific probes for HPV16 and HPV18) and when possible by polymerase chain reaction for high-risk HPV. Six cervical carcinomas with adenoid cystic differentiation admixed with various combinations of at least 1 other pattern of differentiation, including adenoid basal tumor (epithelioma and/or carcinoma), squamous cell carcinoma (basaloid or keratinizing), and small cell carcinoma were identified in patients ranging in age from 50 to 86 years (mean, 73 y; median, 76 y). All of these tumors were characterized by diffuse p16 expression. High-risk HPV was detected in 5 of 6 tested cases: 4 cases by in situ hybridization (all positive for HPV-wide-spectrum and HPV16) and 1 by polymerase chain reaction (HPV45). Seven pure adenoid cystic carcinomas (6 vulvar and 1 cervical) were identified in patients ranging in age from 27 to 74 years (mean, 48 y; median, 48 y). All of these tumors were characterized by variable p16 expression ranging from very limited to more extensive but never diffuse. No high-risk HPV was detected in any of these pure tumors. Lower female genital tract carcinomas with adenoid cystic differentiation appear to comprise 2 pathogenetically distinct groups. Cervical carcinomas with mixed differentiation, including adenoid cystic, adenoid basal, squamous, and small cell components, are etiologically related to high-risk HPV and can be identified by diffuse

    Candida is a commensal organism that is frequently found in the human gastrointestinal tract. It is the most common organism that causes pancreatic fungal infections. However, magnetic resonance imaging findings of Candida infection in the pancreas have not been described. We report imaging findings of pancreatic candidiasis in a patient in immunocompetent condition. It presented as a multi-septated cystic mass with a peripheral solid component in the background of pancreatitis and restricted diffusion on diffusion-weighted image that mimicked a malignant pancreatic cystic tumor.

    Pancreatic neuroendocrine tumors and their hepatic metastases have an inconsistent appearance with only a small percentage of lesions appearing as cystic masses in computed tomography (CT) and magnetic resonance imaging (MRI). Therefore, they can be mistaken as benign or infectious lesions, which can lead to a false diagnosis with delayed or inadequate treatment. We reported a patient with upper abdominal pain that lasted for several months, caused by a huge cystic neuroendocrine carcinoma of the liver. This was mistakenly interpreted as a complicated or hydatid cyst, and the findings in the CT and MRI was presented.

  7. Effectiveness of surgical decompression in the treatment of a calcifying cystic odontogenic tumor

    Full Text Available The calcifying odontogenic cystic tumor (CCOT is a benign lesion of odontogenic origin characterized by an ameloblastoma-like epithelium with ghost cells that may calcify. Despite broadly considered as a cyst, some investigators prefer to classify it as a neoplasm. Clinically, it occurs predominantly during the third decade of life. No difference in gender prevalence has been observed nor predilection of the lesion between maxilla and mandible. The most affected region extends from the incisor tooth to bicuspids. The classic treatment of the lesion is full excision, although a different approach may be determined by the possible association with another odontogenic tumor. Depending on the tumor size and the vicinity with important structures, decompression may be undertaken before its complete removal. The present report describes a case of CCOT with large proportions, located at the right maxilla and extending to the maxillary sinus, nasal cavity, and orbital floor. The treatment option was surgical decompression as the initial procedure, with satisfactory outcome. After partial remission, the lesion was fully removed, and the post-operative follow-up was uneventful.

    Gamma Knife surgery (GKS) has gained increasing relevance in the treatment of metastatic brain tumors, but many metastatic tumors contain a large cystic component and often exceed the size limit for GKS. For such lesions, the authors adopted a procedure in which stereotactic aspiration is first performed and followed immediately by GKS on the same day. In this paper, the authors describe this 1-day combined procedure and evaluate its efficacy. Between 2005 and 2010, 25 cystic metastases in 25 patients were treated at Dokkyo Medical University. The patients first underwent MRI and stereotactic aspiration of the cyst while stationary in a Leksell stereotactic frame; immediately afterward, the patients underwent a second MR imaging session and Gamma Knife treatment. Tumor volume reduction, tumor control rate, and overall survival were examined. Tumor volume, including the cystic component, decreased from 8.0-64.2 cm(3) (mean 20.3 cm(3)) to 3.0-36.2 cm(3) (mean 10.3 cm(3)) following aspiration, and the volume of 24 of 25 lesions decreased to less than 16.6 cm(3), which is equivalent to the volume of a 3.16-cm sphere. At least 20 Gy was delivered to the entire lesion in 24 of 25 cases. Good tumor control was obtained in 16 of 21 cases that could be evaluated during a median follow-up period of 11 months (range 1-27 months); however, reaccumulation of cyst contents was observed in 2 patients who required Ommaya reservoir placement. The 1-day aspiration plus GKS procedure is an effective and time-efficient treatment for large cystic brain metastases.

    Full Text Available Intracranial germ cell tumors are uncommon and account for only 0.3–3.4% of all intracranial tumors. Teratomas are a subset of these neoplasms, and their finding in brain structures is exceptionally rare, and occurrence within the skull base is quite novel. The authors report the case of a 57-year-old male patient who presented with vision changes, incontinence, ataxia, and altered mental status of 1 week’s duration. Imaging revealed a large intrasellar mass with suprasellar extension, involvement of the ventricular system, and marked hydrocephalus with the enlargement of the lateral and third ventricles. The patient underwent a pterional craniotomy/transsylvian approach for resection of the mass. Postoperative histological examination of the resected mass was confirmatory for a mature cystic teratoma. This was followed by radiotherapy, stereotactic radiosurgery, and adjuvant radiotherapy. At the most recent followup, approximately 4 years later, the patient is doing well with improved vision since the operation. This report highlights our experience with a teratoma in a very unusual location, and we review the relevant literature.

    Mesenteric fibromatosis, also known as mesenteric desmoids, is part of the clinical-pathologic spectrum of deep fibromatosis, which encompasses a group of benign fibro-proliferative processes that are locally aggressive and have the capacity to infiltrate or recur without metastasis. Case of a 45-year-old man, with a history of hypertension and lung fibrosis, presenting for a left abdominal mass, which was found incidentally during his lung fibrosis imaging. He complained of constipation due to pressure upon his bowel leading to difficulty in defecation. Although there are many overlapping criteria between gastrointestinal stromal tumors and mesenteric fibromatosis, making it difficult to discriminate between the two, there are differences that are unique to mesenteric fibromatosis that should be noticed during the diagnosis. In this case, mesenteric fibromatosis was unusual as it is not associated with Gardner's syndrome, desmoid tumors, nor familial adenomatous polyposis, but was an incidental finding.

    Full Text Available Abstract Background Adenoid cystic carcinomas are rare tumors with an indolent clinical course, but frequent local relapses. The identification of tumors with a higher relapse risk seems to be interesting. Hence we investigated parameters of glucose metabolism, which were found associated with poor prognosis in other malignancies. Methods Specimen of 29 patients were investigated immunohistochemically with antibodies against p-AKT, TKTL-1 (transketolase-like 1, M2PK (M2 pyruvate kinase, and GLUT-1. Proliferation was investigated by staining with Ki67. The tumors were located at the major or minor salivary glands. Only the typical cribriform subtype was investigated. The initial tumor stage was pT1 or pT2. Results Expression of p-AKT was significantly (P = 0.036 associated with a higher relapse risk in multivariate analysis. Low expression of M2PK was non-significantly (P = 0.065 predictive for a higher risk. TKTL-1 and GLUT-1 were expressed in the majority of cases, albeit not associated with relapse risk. Conclusion Adenoid cystic carcinomas positive for p-AKT show a higher relapse risk. However, other parameters of glucose metabolism investigated here or proliferation (Ki67 were not predictive in this entity. Our findings demonstrate a possible background for therapeutic approaches targeting the inhibition of PI3K/AKT pathway.

    PurposeSelective internal radiotherapy (SIRT) with the beta emitter yttrium-90 (Y90) is a rapidly developing therapy option for unresectable liver malignancies. Nontarget irradiation of the gallbladder is a complication of SIRT. Thus, we aimed to assess different strategies to avoid infusion of Y90 into the cystic artery (CA).MethodsAfter hepatic digital subtraction angiography and administration of technetium-99m-labeled human serum albumin ({sup 99}mTc-HSA), 295 patients with primary or secondary liver tumors underwent single-photon emission computed tomography/computed tomography (SPECT/CT). Different measures were taken before repeated Y90 mapping and SIRT to avoid unintended influx into the CA where necessary. Clinical symptoms, including pain, fever, or a positive Murphy sign, were assessed during patient follow-up.ResultsA significant {sup 99}mTc-HSA accumulation in the gallbladder wall (higher {sup 99}mTc-HSA uptake than in normal liver tissue) was seen in 20 patients. The following measures were taken to avoid unintended influx into the CA: temporary/permanent occlusion of the CA with gelfoam (n = 5)/microcoil (n = 1), induction of vasospasm with a microwire (n = 4), or altering catheter position (n = 10). Clinical signs of cholecystitis were observed in only one patient after temporary CA occlusion with gelfoam and were successfully treated by antibiotics. Cholecystectomy was not required for any patient.ConclusionIt is important to identify possible nontarget irradiation of the gallbladder. The risk for radiation-induced cholecystitis can be easily minimized by temporary or permanent CA embolization, vasospasm induction, or altering the catheter position.

    Zheng, Jinfeng; Geng, Ming; Li, Peifeng; Li, Yi; Cao, Yongcheng

    2013-01-01

    A 48-year-old woman presented with left abdominal pain and fullness. Computed tomography scan revealed a multicystic mass with multifocal mural nodules. Histologic examination showed a mucinous cystic tumor with cystadenoma, borderline malignant cystadenoma and cystadenocarcinoma, which were associated with sarcoma-like mural nodules (SLMNs) and multifocal anaplastic carcinoma. Mural nodules showed a positive reaction for CD56 and vimentin, but were negative for cytokeratin 7 and SMA. She underwent postoperative chemotherapy and is currently under follow-up; no recurrence or metastases were found in the first year of follow-up. Ovarian mucinous cystic tumor with SLMNs and foci of anaplastic carcinoma is extremely rare. To our knowledge, this case reports the most complex neoplastic and reactive components. Our findings shed some light on the pathogenesis of this rather rare carcinoma. We think that the formation of SLMNs may be the result of the reactive proliferation of undifferentiated mesenchymal cells, while the anaplastic carcinoma may be derived from mucinous epithelium. Moreover, because of difficulties encountered in their differential diagnosis, we think that the existence of foci of anaplastic carcinoma along with SLMNs necessitates careful histologic and immunohistochemical analysis of mural nodules for the determination of treatment and prognosis.

    2009-06-01

    Full Text Available Abstract Background Malignant transformation of mature cystic teratoma is a rare complication. While any of the constituent tissues of a teratoma has the potential to undergo malignant transformation, squamous cell carcinoma is the most commonly associated malignancy. Renal carcinoid tumors are rare and frequently associated with horseshoe kidney and renal teratoma. Renal teratoma rarely presents together with carcinoid tumor or adenocarcinoma. To the best of our knowledge, there has never been a report of renal teratoma coexisting with both carcinoid tumor and adenocarcinoma. Methods Here, we present a unique and first case of synchronous primary carcinoid tumor and moderately differentiated adenocarcinoma arising within mature cystic teratoma of horseshoe kidney in a 50-year-old female. Lumbar spine X-ray, done for her complaint of progressive chronic low back pain, accidentally found a large calcification overlying the lower pole of the right kidney. Further radiologic studies revealed horseshoe kidney and a large multiseptated cystic lesion immediately anterior to the right renal pelvis with central calcification and peripheral enhancement. She underwent right partial nephrectomy. Results Macroscopically, the encapsulated complex solid and multiloculated cystic tumor with large calcification, focal thickened walls and filled with yellow-tan gelatinous material. Microscopically, the tumor showed coexistent mature cystic teratoma, moderately differentiated adenocarcinoma and carcinoid tumor. Immunohistochemically, alpha-methylacyl-coenzyme A-racemase, calretinin, CD10 and thyroid transcription factor-1 were negative in all the three components of the tumor. The teratomatous cysts lined by ciliated epithelium showed strong staining for cytokeratin 7 and pancytokeratin, and those lined by colonic-like epithelium showed strong staining for CDX2, cytokeratin 20 and pancytokeratin, but both were negative for calretinin. Additionally, the

    Ameloblastoma is a locally aggressive benign epithelial odontogenic tumor, while unicystic ameloblastoma is a relatively less aggressive variant. Although rare in unicystic or cystic ameloblastoma, granular cell change in ameloblastoma is a recognized phenomenon. The purpose of the present article is to report a case of cystic granular cell ameloblastoma in 34-year old female.

    Full Text Available Cystic nephroma is a rare, benign multicystic lesion of the kidney. This tumor occurs both in children and in adults. In children, it is highly prevalent in males; in adults, it is more frequent in women. The term “cystic nephroma” represents two apparently different entities: pediatric cystic nephroma, a benign form thought to originate from metanephric tissue, and adult cystic nephroma, considered as a lesion of mixed epithelial stromal tumor. The clinical presentation may be a palpable mass or nonspecific symptoms such as abdominal pain, hematuria, and urinary tract infections. In this review, we summarize the ultrasound imaging features of cystic nephroma and describe the characteristics of the most common renal cystic lesions and the differential diagnosis of cystic nephroma with other renal cystic lesions.

    Full Text Available To achieve complete anatomic central hepatectomy for a large tumor compressing surrounding vessels, transection by an anterior approach is preferred but a skillful technique is necessary. We propose the modified technique of Belghiti’s liver hanging maneuver (LHM. The case was a 77-year-old female with a 6-cm liver cystic tumor in the central liver compressing hilar vessels and the right hepatic vein. At the hepatic hilum, the spaces between Glisson’s pedicle and hepatic parenchyma were dissected, which were (1 the space between the right anterior and posterior Glisson pedicles and (2 the space adjacent to the umbilical Glisson pedicle. Two tubes were repositioned in each space and ‘double LHM’ was possible at the two resected planes of segments 4, 5 and 8. Cut planes were easily and adequately obtained and the compressed vessels were secured. Double LHM is a useful surgical technique for hepatectomy for a large tumor located in the central liver.

    Acromegaly is a clinical syndrome caused by the overproduction of growth hormone (GH) and also known as a rare disease. Clinical, biochemical, and radiological features are often indistinguishable between GH-producing hypophysis adenomas and ectopic GH-releasing hormone (GHRH)-producing tumors. A 40-year-old woman presented to us with her growing feet, hands especially fingers, and enlarging nose. Biochemical diagnosis of acromegaly was made by measuring insulin-like growth factor-1 (IGF-1) level and glucose-suppressed GH estimation. Her spot IGF-1 level was 1300 ng/ml (90-226 ng/ml). The basal GH was 30 ng/l, and 60- and 120-min GH levels after 75-g oral glucose load were 29 and 40 ng/l, respectively. Magnetic resonance imaging (MRI) of pituitary was normal. There was no pituitary adenoma or pituitary hyperplasia. Extrapituitary ectopic hypersecretion of GH or GHRH-secreting tumor search was done by high-resolution computed tomography (CT) of chest and whole abdomen. Abdomen CT revealed 9.5 × 8 cm pelvic mass, which included calcific regions and solid component. The specimen's immunohistochemical staining with GH was positive but interestingly GHRH was negative. According to immunohistochemical staining, the patient's diagnosis was ectopic acromegaly due to a GH-secreting neuroendocrine-differentiated tumor developed from an ovarian mature cystic teratoma. Herein, we present excellent illustration of an unusual and confusing clinical scenario of ectopic acromegaly.

    Reversion-inducing cysteine-rich protein with kazal motifs (RECK), a novel tumor suppressor gene that negatively regulates matrix metalloproteinases (MMPs), is expressed in various normal human tissues but downregulated in several types of human tumors. The molecular mechanism for this downregulation and its biological significance in salivary adenoid cystic carcinoma (SACC) are unclear. In the present study, we investigated the effects of a DNA methyltransferase (DNMT) inhibitor, 5-aza-2′deoxycytidine (5-aza-dC), on the methylation status of the RECK gene and tumor invasion in SACC cell lines. Methylation-specific PCR (MSP), Western blot analysis, and quantitative real-time PCR were used to investigate the methylation status of the RECK gene and expression of RECK mRNA and protein in SACC cell lines. The invasive ability of SACC cells was examined by the Transwell migration assay. Promoter methylation was only found in the ACC-M cell line. Treatment of ACC-M cells with 5-aza-dC partially reversed the hypermethylation status of the RECK gene and significantly enhanced the expression of mRNA and protein, and 5-aza-dC significantly suppressed ACC-M cell invasive ability. Our findings showed that 5-aza-dC inhibited cancer cell invasion through the reversal of RECK gene hypermethylation, which might be a promising chemotherapy approach in SACC treatment.

    Full Text Available Tumor sections from nonneoplastic (n=15, benign (n=28, and malignant ovarian tumors (n=20 were obtained from 63 women. Immunohistochemistry of the tumor sections demonstrated that inducible nitric oxide synthase (iNOS expression was increased in ovarian cancer samples compared to nonneoplastic or benign tumor samples. Using the Griess method, nitric oxide (NO metabolite levels were also found to be elevated in malignant tumor samples compared to benign tumor samples (P80 μM were more frequent than NO levels <80 μM, and iNOS expression in well-differentiated carcinomas was greater than in moderately/poorly differentiated carcinomas (P<.05. These data suggest an important role for NO in ovarian carcinogenesis.

    Full Text Available If a pediatric abdominal mass is not organomegaly or colonic stool, narrowing the diagnostic possibilities may be difficult, especially in resource-poor areas where ancillary tests and treatment options may be limited. A 2-year-old girl was brought to the rural Kintampo Municipal Hospital in Ghana with a freely moveable, non-tender abdominal mass. A huge mesenteric dermoid cyst was surgically removed. Mesenteric cysts are rare intra-abdominal lesions, most commonly occurring in children < 10 years old. Making a preoperative diagnosis is difficult. Dermoid cysts (mature cystic teratoma rarely occur in the mesentery. Poverty, family circumstances and the rural location led to general physicians doing surgery. As in this case, due to economic, social and transportation issues common throughout Africa, children with abdominal masses may need at least initial surgery in hospitals without dedicated pediatric surgery or even a trained surgeon.

    Full Text Available Sclerosing stromal tumour of the ovary is an uncommon benign ovarian neoplasm of sex cord stromal origin with distinct clinical and radiological features. We describe a cystic SST in a 35 year old female who presented with right lower abdominal pain. CT-scan revealed a complex ovarian cyst. Right sided Salpingo-oophorectomy was done with intra-operative frozen section which ruled out malignancy. Histopathology showed features consistent with SST ovary. In this report we discuss the differential diagnosis and role of histopathology in confirming the benign nature of the neoplasm,so a conservative surgery can be performed.

    Full Text Available Ovarian teratomas rarely undergo new neoplastic transformation and account for a small percentage of malignant ovarian germ cell neoplasms. Here we report a case of a 51-year-old woman with multiple endocrine neoplasia type I (MEN I who was found to have an ependymoma and neuroendocrine tumor (trabecular carcinoid associated with mature cystic teratoma of her left ovary. The ependymoma component displayed cells with round nuclei and occasional small nucleoli which were focally arranged in perivascular pseudorosettes and true rosettes. Rare mitoses were identified. No necrosis was present. Immunohistochemical staining was positive for S-100 and GFAP. The Ki67 proliferation index was very low (2-3%. In contrast, the endocrine tumor component was composed of small uniform cells with eosinophilic cytoplasm, round nuclei, and speckled chromatin. Immunohistochemical staining was positive for synaptophysin and focally positive for chromogranin. This rare case illustrates that MEN I may have an influence on the pathogenesis of ovarian teratomas as they undergo malignant transformation.

El diagnóstico preoperatorio es importante para un adecuado tratamiento, existiendo en la actualidad valiosas técnicas radiológicas como son los ultrasonidos, la tomografía computarizada y la resonancia magnética. A pesar de todo tenemos que aceptar que nos encontramos ante un grupo de tumores de difícil diagnóstico, debido a la gran variedad de tipos celulares que existen en los mismos.Cystic lesions of the pancreas are infrequent, estimated at only some 1% of all pancreatic tumours and at some 10% of all pancreatic cysts. The pre-operational diagnosis is important for a suitable treatment, with valuable radiological techniques available today such as ultrasound, computerised tomography and magnetic resonance. In spite of this we have to accept that we are facing a group of tumours whose diagnosis is difficult, due to the great variety of cellular types existing within them.

    Full Text Available Celiac disease is a gluten sensitive enteropathy that involves an abnormal immunological response to glutens in wheat, rye etc. It predominantly involves the small intestinal mucosa, though, extra luminal manifestations can also occur. One rare extraluminal manifestation is cavitatory mesenteric lymph node syndrome. It occurs in refractory celiac disease and is associated with poor prognosis due to various complications. The diagnosis is often made on imaging when cystic mesenteric lymph nodes with fat-fluid levels are seen and this can then be confirmed by histopathological examination. We recently had a typical case where we were able to make this diagnosis.

    Abstract Cystic spinal meningioma (CSM) is an uncommon meningioma variant. Extradural CSMs are particularly rare and difficult to distinguish from other intraaxial tumors. This study presents a case of a 36-year-old woman with intraspinal extradual CSM at the thoracolumbar spine. She experienced persistent weakness, progressive numbness, and sensory disturbance in the right lower limb. Magnetic resonance imaging (MRI) of the patient revealed an irregular cystic mass at the thoracic 11 to lumbar 3 levels dorsally. This case was misdiagnosed as other neoplasms prior to surgery because of the atypical radiographic features and location of the tumor. Extradural CSMs should be considered in the differential diagnosis of intraspinal extradural cystic neoplasms. Complete removal of cystic wall provides an optimal outcome, rendering the lesion curable. PMID:26986119

    Lymphangioma usually occurs in children and usually involves the skin. Mesenteric lymphangioma is extremely rare in adults. Typically, lymphangioma appears on computed tomography (CT) as a lower attenuation of a cystic mass, however, some cases appear to be a solid mass. We describe the CT and 18FFDG positron emission tomography/CT appearance in a case of jejunal and mesenteric cavernous lymphangiomatosis mimicking metastasis in an adult patient with rectal cancer.

    2015-03-01

    Mesenteric vasculitis is a rare diagnosis, but it comprises a group of disorders that may have devastating manifestations. It is often difficult to diagnose using clinical symptoms and biomarkers. Vascular imaging often provides the best opportunity for the noninvasive diagnosis of vasculitis and obviates the need for performing a biopsy. The medical management of vasculitis involves controlling the inflammatory process with the use of steroids or other immunosuppressants, but medical therapy does not consistently provide regression of the vascular changes (ie, aneurysms or vascular occlusions) seen at the time of the initial diagnosis. Operative management remains the mainstay of therapy for focal occlusive or aneurysms, but the treatment options for multifocal disease remain challenging. Endovascular treatment is increasingly being used as a first line of treatment for symptomatic vasculitis. Interventionalists should be familiar with the indications and outcomes associated with the various therapeutic options for mesenteric vasculitis-associated occlusive disease and aneurysms.

    Adenoid cystic carcinoma (ACC) is an exocrine gland tumor accounting for approximately 10%-15% of all epithelial salivary neoplasms and occurs most often in the parotid and submandibular glands. Metastatic pituitary tumors are rare, and there is only 1 previously reported case of parotid ACC metastatic to the pituitary. Magnetic resonance elastography (MRE) is a dynamic magnetic resonance imaging (MRI)-based technique that measures the propagation of mechanically induced shear waves through a particular tissue to determine stiffness and offers a method to evaluate tissue consistency. We present the case of a 72-year-old woman with a remote history of parotid gland ACC and subsequent lung metastases presented after a fall that resulted in facial trauma. A non-contrast head computed tomography scan revealed a sellar/suprasellar mass, and follow-up MRI revealed a well-defined, enhancing 3.8-cm lesion. MRE showed the tumor to be firm. The tumor was resected through a transsphenoidal approach and was consistent with the MRE findings. Pathology returned as metastatic ACC. We report the second case of ACC metastatic to pituitary and the first firm pituitary tumor found by MRE and discuss the potential diagnostic value of MRE in pituitary lesions.

    The pituitary tumor transforming gene (PTTG)/securin is an oncogene that is involved in cell cycle regulation and sister chromatid separation. PTTG is highly expressed in various tumors including ovarian tumors, suggesting that PTTG may play a role in ovarian tumorigenesis. Overexpression of PTTG resulted in induction of cellular transformation in vitro and tumor formation in nude mice. To ascertain PTTG function in ovarian tumorigenesis, we generated a transgenic mouse model of PTTG by cloning PTTG cDNA downstream of Mullerian inhibitory substance type II receptor gene promoter (MISIIR) in order to target the ovarian surface epithelium. By screening of transgenic animals, we identified five founders (four males and one female). Using the four male founders, we developed four transgenic lines. PTTG expression was increased in ovarian surface epithelium, ovarian granulosa cells, as well as in the pituitary gland. Transgenic females did not develop any visible ovarian tumors at 8-10 months of age; however, there was an overall increase in the corpus luteum mass in transgenic ovary, suggesting increased luteinization. These changes were associated with an increase in serum LH and testosterone levels. In addition, there was a generalized hypertrophy of the myometrium of MISIIR-PTTG transgenic uteri with cystic glandular and hyperplasia of the endometrium. Based on these results, we conclude that the overexpression of PTTG may be required to initiate precancerous conditions but is not sufficient to induce ovarian tumorigenesis and may require another partner to initiate cellular transformation.

    Superior mesenteric vein thrombosis was identified on computed tomographic scans in six patients. In each case, contrast-enhanced scans showed a high-density superior mesenteric vein wall surrounding a central filling defect. Four fo the six patients had isolated superior mesenteric vein thrombosis. A fifth patient had associated portal vein and splenic vein thrombosis, and the sixth patient had associated portal vein and inferior vena cava thrombosis. One of the six patients had acute ischemic bowel disease. The other five patients did not have acute ischemic bowel symptoms associated with their venous occlusion. This study defines the computed tomographic appearance of mesenteric vein thrombosis.

    Background: Abdominal lymphangioma is a rare benign congenital malformation of the mesenteric and/or retroperitoneal lymphatics. Clinical presentation is variable and may be misleading; therefore, complex imaging studies are necessary in the evaluation of this condition. US and CT have a major role in the correct preoperative diagnosis and provide important information regarding location, size, adjacent organ involvement, and expected complications. Objective: To evaluate the clinical and imaging findings of seven children with proven abdominal cystic lymphangioma. Materials and methods: Clinical and imaging files of seven children with pathologically proven abdominal lymphangioma, from three university hospitals, were retrospectively evaluated. Patient's ages ranged from 1 day to 6 years (mean, 2.2 years). Symptoms and signs included evidence of inflammation, abnormal prenatal US findings, chronic abdominal pain, haemorrhage following trauma, clinical signs of intestinal obstruction, and abdominal distension with lower extremities lymphoedema. Plain films of five patients, US of six patients and CT of five patients were reviewed. Sequential imaging examinations were available in two cases. Results: Abdominal plain films showed displacement of bowel loops by a soft tissue mass in five of six patients, two of them with dilatation of small bowel loops. US revealed an abdominal multiloculated septated cystic mass in five of six cases and a single pelvic cyst in one which changed in appearance over 2 months. Ascites was present in three cases. CT demonstrated a septated cystic mass of variable sizes in all available five cases. Sequential US and CT examinations in two patients showed progressive enlargement of the masses, increase of fluid echogenicity, and thickening of walls or septa in both cases, with multiplication of septa in one case. At surgery, mesenteric lymphangioma was found in five patients and retroperitoneal lymphangioma in the other two

    Full Text Available We present a case of cystic lymphangioma of the mediastinum complicated with situs inversus totalis. The 70-year-old man underwent thoracoscopic resection of a mediastinal cystic tumor, which was diagnosed as cystic lymphangioma. Cystic lymphangiomas are congenital cystic abnormalities of the lymphatic system. The head and neck area is often involved while the mediastinum is rarely affected. The rarity of this case is further attributed to the coexistence of situs inversus totalis.

    Full Text Available Abstract Background Preoperative characterization of complex solid and cystic adnexal masses is crucial for informing patients about possible surgical strategies. Our study aims to determine the usefulness of apparent diffusion coefficients (ADC for characterizing complex solid and cystic adnexal masses. Methods One-hundred and 91 patients underwent diffusion-weighted (DW magnetic resonance (MR imaging of 202 ovarian masses. The mean ADC value of the solid components was measured and assessed for each ovarian mass. Differences in ADC between ovarian masses were tested using the Student’s t-test. The receiver operating characteristic (ROC was used to assess the ability of ADC to differentiate between benign and malignant complex adnexal masses. Results Eighty-five patients were premenopausal, and 106 were postmenopausal. Seventy-four of the 202 ovarian masses were benign and 128 were malignant. There was a significant difference between the mean ADC values of benign and malignant ovarian masses (p -3 mm2/s may be the optimal one for differentiating between benign and malignant tumors. Conclusions A high signal intensity within the solid component on T2WI was less frequently in benign than in malignant adnexal masses. The combination of DW imaging with ADC value measurements and T2-weighted signal characteristics of solid components is useful for differentiating between benign and malignant ovarian masses.

    Full Text Available Double balloon enteroscopy (DBE is a revolutionary procedure in which the entire small bowel can be visualized endoscopically. DBE has the advantage of both diagnostic and therapeutic capabilities in the setting of small bowel neoplasms and vascular malformations. We present a unique case of a 76-year-old female who underwent small bowel DBE tattoo marking of a distal small bowel tumor complicated by development of severe abdominal pain postprocedure secondary to bowel air embolism into the mesenteric veins. Mesenteric air can be seen after other endoscopic procedures such as biopsy, mucosal clip placement and polypectomy, or following a colonoscopy. Mesenteric air embolism following small bowel tattooing procedure has not been previously reported in the literature. Mesenteric air when present may be attributed to mesenteric ischemia and can subject the patient to unnecessary surgical intervention if misdiagnosed. Thus, this report holds significance for the radiologist as computed tomography (CT findings of mesenteric air embolism must be evaluated in the context of appropriate clinical history before treatment decisions are made.

    The intestinal lymph pathway plays an important role in the pathogenesis of organ injury following superior mesenteric artery occlusion (SMAO) shock. We hypothesized that mesenteric lymph reperfusion (MLR) is a major cause of spleen injury after SMAO shock. To test this hypothesis, SMAO shock was induced in Wistar rats by clamping the superior mesenteric artery (SMA) for 1 h, followed by reperfusion for 2 h. Similarly, MLR was performed by clamping the mesenteric lymph duct (MLD) for 1 h, followed by reperfusion for 2 h. In the MLR+SMAO group rats, both the SMA and MLD were clamped and then released for reperfusion for 2 h. SMAO shock alone elicited: 1) splenic structure injury, 2) increased levels of malondialdehyde, nitric oxide (NO), intercellular adhesion molecule-1, endotoxin, lipopolysaccharide receptor (CD14), lipopolysaccharide-binding protein, and tumor necrosis factor-α, 3) enhanced activities of NO synthase and myeloperoxidase, and 4) decreased activities of superoxide dismutase and ATPase. MLR following SMAO shock further aggravated these deleterious effects. We conclude that MLR exacerbates spleen injury caused by SMAO shock, which itself is associated with oxidative stress, excessive release of NO, recruitment of polymorphonuclear neutrophils, endotoxin translocation, and enhanced inflammatory responses.

    Although saponification of the pancreas is a frequent finding on computed tomography, saponification of extrapancreatic mesenteric sites has not been previously recognized. A case is presented of acute pancreatitis in which serial scans over a four-year period documented calcifications in old extrapancreatic phlegmons. Saponification from pancreatitis should be considered in the differential diagnosis of mesenteric calcifications.

    Full Text Available Abdominal cystic lymphangioma is a rare, benign, congenital tumor. It is an developmental abnormality of the lymphatic system. Males are relatively more affected and 90% of the cases are under 5 years of age. Multilocular cystic lesion with septations is seen on abdominal ultrasonography. As echogenicity can vary depending on the content of the cyst like cellular debris, hemorrhage or chylous, liquid-liquid or fat-liquid levels can be observed. Definitive treatment is total excision. Cyst aspiration is not an effective method and nearly always ends with recurrence. Computerized tomography and magnetic resonance imaging findings of sonographically detected retroperitoneal cystic lymphangioma in a newborn girl with abdominal distention are discussed in this paper.

  11. Mutations in the c-Kit Gene Disrupt Mitogen-Activated Protein Kinase Signaling during Tumor Development in Adenoid Cystic Carcinoma of the Salivary Glands

    Full Text Available The Ras/mitogen-activated protein kinase (MAPK pathway is considered to be a positive regulator of tumor initiation, progression, and maintenance. This study reports an opposite finding: we have found strong evidence that the MAPK pathway is inhibited in a subset of adenoid cystic carcinomas (ACCs of the salivary glands. ACC tumors consistently overexpress the receptor tyrosine kinase (RTK c-Kit, which has been considered a therapeutic target. We performed mutational analysis of the c-Kit gene (KIT in 17 cases of ACC and found that 2 cases of ACC had distinct missense mutations in KIT at both the genomic DNA and messenger RNA levels. These mutations caused G664R and R796G amino acid substitutions in the kinase domains. Surprisingly, the mutations were functionally inactive in cultured cells. We observed a significant reduction of MAPK (ERK1/2 activity in tumor cells, as assessed by immunohistochemistry. We performed further mutational analysis of the downstream effectors in the c-Kit pathway in the genes HRAS, KRAS, NRAS, BRAF, PIK3CA, and PTEN. This analysis revealed that two ACC tumors without KIT mutations had missense mutations in either KRAS or BRAF, causing S17N K-Ras and V590I B-Raf mutants, respectively. Our functional analysis showed that proteins with these mutations were also inactive in cultured cells. This is the first time that MAPK activity from the RTK signaling has been shown to be inhibited by gene mutations during tumor development. Because ACC seems to proliferate despite inactivation of the c-Kit signaling pathway, we suggest that selective inhibition of c-Kit is probably not a suitable treatment strategy for ACC.

    Full Text Available INTRODUÇÃO: Cistos mesentéricos são tumores abdominais raros, que podem acometer pacientes de todas as faixas etárias, sendo mais comuns em mulheres na quarta década de vida. Essas neoplasias são geralmente assintomáticas e diagnosticadas por acaso. Seu tratamento é baseado na retirada do cisto, por laparotomia ou laparoscopia, embora em alguns casos possa ser necessária a ressecção de segmento intestinal. O prognóstico é bom e a recorrência é baixa. RELATO DO CASO: Mulher de 40 anos de idade, obesa, hipertensa e diabética, apresentou história de dor abdominal contínua de pouca intensidade no hipocôndrio esquerdo e epigástrio, sem irradiações, durante cerca de três meses. Após um mês do início dos sintomas percebeu massa em andar superior do abdome palpável desde o epigástrio até o flanco esquerdo, de consistência endurecida, pouco móvel, superfície regular e dolorosa. A tomografia computadorizada de abdome evidenciou formação cística de paredes finas e lisas, medindo 12,9 x 11,6 x 9,9 cm, situada em flanco esquerdo, em região mesentérica, deslocando estruturas adjacentes, sugestiva de cisto mesentérico. À laparotomia evidenciou-se massa cística, com aproximadamente 10 cm de diâmetro, de parede fina e lisa, cor amarelada, com vasos tortuosos na superfície, sem aderência à estruturas adjacentes, localizada no mesojejuno a cerca de 50 cm da flexura duodenojejunal. O cisto foi completamente retirado e seu conteúdo era líquido brancacento e inodor, sugestivo de quilo. O exame anatomopatológico revelou cisto mesotelial benigno mesentérico. CONCLUSÃO: O tratamento desses cistos consiste basicamente na sua retirada ou descapsulação, que pode ser realizado de preferência por via laparoscópica.INTRODUCTION: Mesenteric cysts are rare abdominal tumors that may occur in patients at any age and are more common in women at the age of forty.

    To describe the radiological appearance of different histological subtypes of mesenteric and omental cysts: lymph angioma, enteric duplication cysts, enteric and mesothelial, and non-pancreatic pseudocysts. The basis of this study is the clinical, radiological and pathological review os 13 cases from our departmental archives involving cystic lesions of the omentum or mesentery: 3 lympangiomas, one enteric duplication cyst, 7 mesothelial cysts and 2 non-pancreatic pseudocysts. The sex distribution was 9 women and 4 men. Most common clinical findings were pain and abdominal distension. Echography (ultra-sound scanning) was performed in 8 cases, abdominal x-ray in 10 and computerized tomography (CT in 13 cases. In the ultra-sound and CT studies, lymphangiomas appeared as large thin-walled multilocular cystic lesions. Mesonthelial cysts were observed as unilocular thin-walled (calcified in 2 cases) cystic lesions of varying size. Duplication cysts were unilocular, seemingly liquid-filled under ultrasound scan and with a thick calcified wall. the non-pancreatic pseudocysts were of varying size, heterogeneous and thick-walled. Aside from being able to determine whether abdominal masses are cystic in nature, ultrasound scan and CT can determine whether such are mesenteric or omental in origin. They can also determine the cystic nature of an abdominal mass which would be helpful in narrowing down diagnostic possibilities. It is important to remember that some malignant neoplasia can occasionally resemble cystic lesions with imaging techniques. (Author) 7 refs.

    2017-02-01

    Vasculitis of the mesenteric circulation is an uncommon but life-threatening manifestation of systemic vasculitis. Initial symptoms are frequently non-specific and therefore patients often present to primary care physicians and gastroenterologists with abdominal pain or gastrointestinal bleeding. Given the severity of the conditions associated with mesenteric vasculitis, it is imperative to appropriately diagnose and initiate treatment of suspected cases. This review will focus on diseases commonly associated with vasculitis of the mesenteric vessels. Imaging characteristics and clinical features assisting in diagnosis as well as initial approaches to treatment are emphasized. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Different optical spectral characteristics were observed in a necrotic transmissible venereal tumor (TVT) and a cystic lesion in the same canine prostate by triple-wavelength trans-rectal optical tomography under trans-rectal ultrasound (TRUS) guidance. The NIR imager acquiring at 705nm, 785nm and 808nm was used to quantify both the total hemoglobin concentration (HbT) and oxygen saturation (StO2) in the prostate. The TVT tumor in the canine prostate as a model of prostate cancer was induced in a 7-year old, 27 kg dog. A 2 mL suspension of 2.5x106 cells/mL of homogenized TVT cells recovered from an in vivo subcutaneously propagated TVT tumor in an NOD/SCID mouse were injected in the cranial aspect of the right lobe of the canine prostate. The left lobe of the prostate had a cystic lesion present before TVT inoculation. After the TVT homogenate injection, the prostate was monitored weekly over a 9-week period, using trans-rectal NIR and TRUS in grey-scale and Doppler. A TVT mass within the right lobe developed a necrotic center during the later stages of this study, as the mass presented with substantially increased [HbT] in the periphery, with an area of reduced StO2 less than the area of the mass itself shown on ultrasonography. Conversely, the cystic lesion presented with slightly increased [HbT] in the periphery of the lesion shown on ultrasound with oxygen-reduction inside and in the periphery of the lesion. There was no detectable change of blood flow on Doppler US in the periphery of the cystic lesion. The slightly increased [HbT] in the periphery of the cystic lesion was correlated with intra-lesional hemorrhage upon histopathologic examination.

    BACKGROUND: Pancreatic adenocarcinoma remains the fourth leading cause of cancer-related death and is one of the most aggressive human tumors. At present, surgical resection is the only potentially curative treatment. Early neck division is inadequate when invasion of the superior mesenteric artery (SMA) is suspected or in cases of replaced or accessory right hepatic artery. Malignant periampullary tumors often invade retroperitoneal peripancreatic tissues and a positive resection margin is associated with a poor long-term survival. DATA SOURCES: English-language medical databases, PubMed, ELSEVIER and SPRINGERLINK, were searched for articles on"posterior approach pancreaticoduodenectomy","superior mesenteric artery ifrst approach", "retroperitoneal tissue","hanging maneuver", and related topics. RESULTS:The modiifcation allowed the surgeon to early identify the nonresectability of a replaced right hepatic artery if present, enabling complete dissection of the right side of the SMA and portal vein as well as complete excision of the retroportal pancreatic lamina. CONCLUSION: Pancreaticoduodenectomy with early retro-pancreatic dissection is a useful and safe technical variant, which is indicated for the improvement of the safety and curative effect of the procedure.

    2016-01-01

    BACKGROUND: Serum cancer antigen 19-9 (CA19-9) pro-vides additional information about mucinous cystic pancre-atic neoplasm (MPN). This study was undertaken to assess both CA19-9 and carcinoembryonic antigen (CEA) serum concentrations in consecutive patients affected by MPNs and other chronic benign and malignant pancreatic diseases. We also evaluated whether serum CA19-9 and CEA determina-tions provide additional information such as the presence of invasive carcinoma in MPN patients. METHODS: Serum CA19-9 and CEA from 91 patients with pancreatic diseases were tested by commercially available kits at the time of diagnosis. The upper reference limit of serum CA19-9 was 37 U/mL and that of serum CEA was 3 ng/mL. RESULTS: Thirty-ifve patients was diagnosed with chronic pancreatitis (CP), 32 with MPN, and 24 with pancreatic ductal adenocarcinoma (PDAC) conifrmed histologically. Surgery was carried out in 5 CP patients, in 10 MPN patients (7 of them had severe dysplasia), and 9 PDAC patients. Serum CA19-9 activity was high in 12 (34.3%) CP patients, in 7 (21.9%) MPN patients, and in 12 (50.0%) PDAC patients (P=0.089). High se-rum CEA concentrations were noted in 6 (17.1%) CP patients, in 6 (18.8%) MPN patients, and in 12 (50.0%) PDAC patients (P=0.010). In the 7 MPN patients associated with histological-ly conifrmed severe dysplasia, 3 (42.9%) patients had elevated serum activity of serum CA19-9, and 2 (28.6%) patients had high levels of CEA. CONCLUSION: Serum determination of oncological markers is not useful in selecting MPN patients with malignant changes.

    2016-01-01

    Background: Cystic vestibular schwannomas (VS) form a rare subgroup that differs from the solid variant clinically, radiologically, and histopathologically. These tumors also vary in their surgical outcome and carry a different risk of post-operative complications. We analyzed our series of 64 patients with cystic VS and discuss the technical difficulties related to total excision of these tumors and focus on complication avoidance. Materials and Methods: A retrospective review of cystic VS surgically managed over a span of 11 years. The case records were evaluated to record the clinical symptoms and signs, imaging findings, surgical procedure, complications, and follow-up data. Post-operative facial nerve palsy was analyzed with respect to tumor size and tumor type. Results: Progressive hearing impairment was the most common initial symptom (76.6%). Atypical initial symptoms were present in 15 patients (23.4%). Preoperatively, 78% patients had good facial nerve function (HB grade 1, 2) and 22% had intermediate (HB grade 3, 4) to poor (HB grade 5 and 6) function. Mean tumor size was 4.1 cm. Complete tumor removal was achieved in 53 patients (83%). The facial nerve was anatomically intact but thinned out after tumor excision in 38 patients (59.4%). Ninety percent patients had either intermediate or poor facial nerve function at follow-up. Poor facial nerve outcome was associated with giant tumors and peripherally located, thin-walled cystic tumors. Conclusion: Resection of cystic VS is complicated by peritumoral adhesions of the capsule to the nerve. Extensive manipulation of the nerve in order to dissect the tumor–nerve barrier results in worse facial nerve outcome. The outcome is worse in peripherally located, thin-walled cystic VS as compared to centrally located, thick-walled cystic tumors. Subtotal excision may be justified, especially in tumors with dense adhesion of the cyst wall to the facial nerve in order to preserve nerve integrity. PMID:27366248

    Full Text Available Introduction: Ovarian cysts are relatively rare in children. Mucinous cystadenomas are rarely encountered in adolescent patients and can reach an enormous size. Mural nodules associated with mucinous tumors of the ovary may represent a benign or malignant process."nCase Presentation: Our case was a 15-year-old female, which referred with a painless abdominal distention gradually appearing during six months. There was no specific symptom only mild discomfort of bowel habits with the regular menstruation. On physical examination, there was complete distention of the abdomen without any tenderness. Ultrasonography revealed a large loculated cystic mass in the abdominopelvic cavity, which contained few septations and mural nodules without any vascularity on color Doppler ultrasonography. All other organs appeared normal. On contrast enhanced CT scan, there was a large intra-peritoneal 280×250×170 mm anteriorly located cystic mass which extended from the upper abdomen down to the lower pelvis displacing and compressing adjacent structures posterolaterally. Multiple enhancing septa and two mural nodules were found in the cystic mass. All solid organs appeared normal and no significant adenopathy or ascitis was detected. According to the above findings, omental cysts, adenexal cysts, urachal cysts, mesenteric cysts were our differential diagnosis. A 10 kg mass was resected (an exophytic cyst in the right ovary and histopathology revealed mucinous cystic adenoma of the right ovary with fibrotic mural nodules. No recurrence was detected after one year."nDiscussion: Mucinous cystadenomas are rarely encountered in adolescent patients and can reach an enormous size. The interesting point of this case was not only because of its rarity but also because of its unusual symptomless manifestation and also fibrotic mural nodules."nKeywords: Mucinous Cystic Adenoma, Ovary, Adolescence

    The purpose of this study was to investigate the actual management of mucinous cystic neoplasm (MCN) of the pancreas. A systematic review was performed in December 2009 by consulting PubMed MEDLINE for publications and matching the key words “pancreatic mucinous cystic neoplasm”, “pancreatic mucinous cystic tumor”, “pancreatic mucinous cystic mass”, “pancreatic cyst” and “pancreatic cystic neoplasm” to identify English language articles describing the diagnosis and treatment of the MCN of the pancreas. In total, 16,322 references ranging from January 1969 to December 2009 were analyzed and 77 articles were identified. No articles published before 1996 were selected because MCNs were not previously considered to be a completely autonomous disease. Definition, epidemiology, anatomopathological findings, clinical presentation, preoperative evaluation, treatment and prognosis were reviewed. MCNs are pancreatic mucin-producing cysts with a distinctive ovarian-type stroma localized in the body-tail of the gland and occurring in middle-aged females. The majority of MCNs are slow growing and asymptomatic. The prevalence of invasive carcinoma varies between 6% and 55%. Preoperative diagnosis depends on a combination of clinical features, tumor markers, computed tomography (CT), magnetic resonance imaging, endoscopic ultrasound with cyst fluid analysis and positron emission tomography-CT. Surgery is indicated for all MCNs.

    Percutaneous transluminal angioplasty and stent placement is now an established treatment option for chronic mesenteric ischemia and is associated with low mortality and morbidity rates. We present a case of reperfusion hemorrhage complicating endovascular repair of superior mesenteric artery stenosis. Although a recognized complication following repair of carotid stenosis, hemorrhage has not previously been reported following mesenteric endovascular reperfusion. We describe both spontaneous cessation of bleeding and treatment with coil embolization.

    Cystic spinal meningioma (CSM) is an uncommon meningioma variant. Extradural CSMs are particularly rare and difficult to distinguish from other intraaxial tumors. This study presents a case of a 36-year-old woman with intraspinal extradual CSM at the thoracolumbar spine. She experienced persistent weakness, progressive numbness, and sensory disturbance in the right lower limb. Magnetic resonance imaging (MRI) of the patient revealed an irregular cystic mass at the thoracic 11 to lumbar 3 levels dorsally. This case was misdiagnosed as other neoplasms prior to surgery because of the atypical radiographic features and location of the tumor. Extradural CSMs should be considered in the differential diagnosis of intraspinal extradural cystic neoplasms. Complete removal of cystic wall provides an optimal outcome, rendering the lesion curable.

    Full Text Available Omental and mesenteric lipomas are very rare benign lesions of mature adipose tissue. They are well-defined, noninvasive, and encapsulated masses that can be discovered in asymptomatic patients or may cause variable nonspecific symptoms depending on their size and location. The omental and mesenteric lipoma has confusing features in ultrasound; however, computed tomography and magnetic resonance imaging can well characterize and demarcate these lesions. Though few cases of mesenteric and omental lipomas have been reported in the literature, but because of its large size and childhood presentation, the case we present, can be one of the largest childhood omental and mesenteric lipomas ever reported. A 6-year-old girl presented with slowly progressing abdominal distension and repeated dull abdominal pain for last 4 years. Abdominal and pelvic computed tomography examination revealed a huge mesenteric and omental lipoma that was resected surgically without any complications.

    We report a new case of nonpacncreatic pseudocyst located in the mesentery in a 39-year-old woman whose personal history was unremarkable. She came to the Emergency Room with symptoms of acute abdomen. Admoninal ultrasound revealed the presence of a thick-walled cystic lesion at the level of the mesogastrium, containing echogenic materials and a fluid-fluid level. Subsequent computed tomography showed that the wall was enhanced by the contrast material and that the lesion arose from the mesentery. There was also a great amount of free peritoneal fluid. The patient underwent emergency surgery to excise a perforated mesenteric cyst. The pathological study of the excised tissue resulted in a diagnosis of mesenteric pseudocyst. (Author) 4 refs.

    Cystic echinococcosis caused by Echinococcus granulosus is still an important health problem in endemic areas. Cystic echinococcosis may involve different organs or areas with the most common sites being the liver and the lungs. Pelvic involvement has previously been reported and was mainly accepted as secondary to cystic echinococcosis in other organs, isolated pelvic involvement is very rare. In this case report, we aimed to present the case with pelvic cystic mass that was finally diagnosed with isolated pelvic cystic echinococcosis in and after the operation, and we would like to draw attention to include "cystic echinococcosis" in the differential diagnosis of pelvic masses.

    Full Text Available Cystic fibrosis (CF is a multisystemic autosomal recessive disease caused by a defect in the expression of CFTR protein, i.e. chloride channel present in the apical membrane of respiratory, digestive, reproductive and sweat glands epithelium. It primarily occurs in the Caucasians, while being considerably or exceptionally rare in persons of other races. Absence, deficit or structural and functional abnormalities of CFTR protein lead to mucosal hyperconcentration in the respiratory, digestive and reproductive systems and malabsorption of chloride and sodium in the sweat glands. Thus, the clinical features of patients’ with CF are predominated by respiratory, digestive and reproductive disorders, as well as the tendency to dehydration in the condition of increased sweating. Beside genotype variations, the degree of disease manifestation is also essentially influenced by various exogenous factors, such as the frequency and severity of respiratory infections, the level of aero-pollution, quality of immunoprophylaxis, patients’ nutritional condition and other. Chloride concentration of over 60 mmol/L in sweat, a high level of immunoreactive chymotrypsinogen in blood and the verification of homozygous mutation of CFTR gene are the basic methods in the diagnostics of the disease. CF belongs to the group of severe and complex chronic diseases, and therefore requires multidisciplinary therapeutic approach. Owing to the improvement of healthcare provision, most patients with CF now survive into adulthood. In addition, their quality of life is also considerably improved.

    Mature teratoma of the ovary is the most common primary ovarian tumor accounting for 15% (10%-20%) of all ovarian neoplasms. Skin and skin adnexal structures are the most common elements identified in mature teratomas. Benign and malignant skin tumors can arise in ovarian teratomas, the most common being epithelial tumors. Melanocytic and adnexal tumors developing in a teratoma are rare and can be easily overlooked. We report 3 cases and review melanocytic and skin adnexal tumors encountered in ovarian teratomas.

    Full Text Available We report five patients with variceal hemorrhage, in three cases secondary to diffuse thrombosis of the portal, superior mesenteric and splenic veins. Mesenteric angiography demonstrated patency of the inferior mesenteric vein (IMV in each, and successful portal decompression by anastomosis of the IMV to the left renal vein (n=4 or the inferior vena cava (n=1 was accomplished. Bleeding was permanently controlled: four patients have survived from one to eight years post-operatively. Because shunt procedures utilizing the IMV are technically straightforward, subtotally decompress the portal system and avoid the right upper quadrant, they may be advantageous in certain clinical settings.

    Objective To investigate the imaging features and differential diagnosis points of common cystic tumors of the pancreas on MSCT and MRI. Methods All imaging data of 41 patients (10 serous cystic neoplasms [SEN], 14 mucinous cystic neoplasms [MCN], 17 intraductal papillary mucinous neoplasms [IPMN]) confirmed by surgery and pathology were retrospectively analyzed. Results Seven serous microcystadenomas manifested as honeycomb masses with small and numerous cysts, lobulated contour, fibrous central scar. Two serous oligocystadenomas (1 unilocular and 1 multilocular) showed as masses with large and less cysts, lobulated contour. One solid serous adenoma markedly enhanced on CT, while T2WI revealed the cystic features. MCN manifested as masses with large and less cysts and smooth contour. IPMN were communicated with pancreatic duct, showed clubbed fingerlike cysts in unilocular and pleomorphic in multilocular. IPMN showed proximal, distal or whole pancreatic duct dilatation, while SEN and MCN only showed proximal dilatation. Conclusion Different shapes of cysts are helpful to differential diagnosis of common cystic tumors of pancreas.

    2011-01-01

    Full Text Available Solid pseudopapillary tumor (SPT of the pancreas is a rare benign or low-grade malignant epithelial tumor that occurs mainly in young females in second to fourth decades of life. Pathologic and imaging findings include a well-defined, encapsulated pancreatic mass with cystic and solid components with evidence of hemorrhage. We report a 23-year-old female who presented with upper abdominal pain of long duration and epigastric mass on palpation. Multidetector-row CT (MDCT demonstrated a large well-defined heterogeneous attenuation mass, containing hyperdense areas of hemorrhage mixed with solid enhancing and cystic non-enhancing areas, arising from the pancreatic body and tail. Splenic vein thrombosis was present with dilated splenoportal collateral vessels between splenic hilum and portal/superior mesenteric veins, with dilated vessels seen in the gastric wall, with patent portal vein, compatible with sinistral portal hypertension. Typical imaging features and age and sex of the patient suggested a diagnosis of SPT of pancreas complicated by segmental portal hypertension due to splenic vein thrombosis. Histopathology of the biopsy material was confirmatory.

    2015-03-01

    Full Text Available The term abdominal fibromatosis refers to sporadic, pelvic, and mesenteric lesions and to all the fibromatosis lesions seen in Gardner's syndrome. Sporadic fibromatosis, however, is very rarer and literature offers a limited number of cases. The 14-year-old female patient presented to our clinic with complaints of indefinite abdominal pain in the epigastric area for the last 2 months, dyspeptic problems, and vomiting after eating. Upon the patient's gastroscopy revealed a mass lesion pressuring the stomach, endoscopic ultrasonography was performed. A hyperechoic mass lesion of 9x5 cm thought to have originated from the pancreatic tail was detected. The mass was surgically excised. Although mesenteric fibromatosis shows the characteristics of a benign tumor pathologically, it is extremely aggressive clinically and has a very high rate of recurrence. These patients should be treated like they have malign tumors and surgeons should perform surgical resection as wide as possible. [Cukurova Med J 2015; 40(1.000: 138-142

    Full Text Available Context The serum carcinoembryonic antigen (CEA is an important prognostic factor in colorectal cancer, however the rectum presents different routes of venous drainage, stating that the level of CEA in peripheral and mesenteric rectal tumors may be different, depending on the location of the tumor in the rectal segment. Objective The goal of this study was to evaluate the relationship between the peripheral and mesenteric venous levels of CEA and the association between these levels and the tumour location in the rectums of patients successfully operated on for rectal carcinoma. Methods Thirty-two patients who were surgically treated for rectal carcinoma were divided into patients with tumours located in the upper rectum (n = 11 or lower rectum (n = 21. The CEA values were assessed by electrochemiluminescence immunoassay. Serum and mesenteric CEA levels were associated with the tumour anatomopathological characteristics: location, histological type, cellular differentiation grade, depth of invasion into the rectal wall, angiolymphatic invasion, tumour, node, and metastasis staging; and the CEA index (≤1.0 or ≥1.0 ng /mL. Results Analysis of the serum CEA values using clinical and anatomopathological parameters revealed no significant association with tumour location, histological type, cellular differentiation grade, depth of invasion into the intestinal wall, and tumour, node, and metastasis staging. The mesenteric CEA levels were significantly associated with the tumour location (P = 0.01. The CEA values in the mesenteric venous blood and the presence of angiolymphatic invasion (P = 0.047 were significantly different. A significant relationship was found between the CEA index value and the rectal tumour location (P = 0.0001. Conclusions The CEA levels were higher in the mesenteric vein in tumours located in the upper rectum and in the presence of angiolymphatic invasion. CEA drainage from lower rectum adenocarcinomas preferentially occurs

  13. A case of cystic hemangioma in mesentery

    Full Text Available A nine-year-old, otherwise healthy girl presented with abdominal pain. On exam, there was a palpable cystic tumor in the left abdomen. According to imaging examinations, we tentatively diagnosed the tumor as lymphangioma of mesentery with bleeding. We planned to perform laparoscopic surgery to remove the tumor. On laparoscopy, cyst aspiration was performed to reduce the volume of the cysts, and the aspirated fluid was found to contain red blood cells. Due to technical difficulties, laparoscopic surgery was converted to open surgery. RBCs were detected in the cyst fluid at the sigmoid colon and intestinal mesentery. Resection of the cystic tumor and sigmoidectomy were performed. On pathologic examination of the tumor, there were multiple cysts but there was no cavernous part. The largest cyst was 6 × 5 × 3 cm. Simple squamous epithelium cells were found along parts of the inner lining of enlarged luminal cysts. On immunohistochemical staining, the tumor was positive for CD31 and CD34, and negative on D2-40 antibody staining. Therefore, we diagnosed this specimen as hemangioma with giant cysts at the mesentery. We conclude that bleeding into cysts of a hemangioma of mesentery might lead to the development of giant cysts and, in turn, a cystic tumor in the abdomen.

    Complete surgical resection with microscopically tumor-free resection margins (R0) is the most important survival determinant for patients with localized pancreatic cancer. The medial and posterior resection margins are the dominant sites of microscopic tumor involvement, and outline the so-called mesopancreas. In this study, we present a modified surgical approach to the superior mesenteric artery, celiac trunc, and mesopancreas during pancreatoduodenectomy, which enables a comfortable exposure and radical en bloc clearance of the mesopancreas and the tissue adjacent to the superior mesenteric artery. The dissection of the mesopancreas is directed from the ventral aspect of the portal vein downward along the superior mesenteric artery and the celiac trunc, before the transection of the duodenal mesentery is accomplished. The described technique complements the established surgical approaches to pancreatic head tumors, and is indicated in the absence of portal vein infiltration. J. Surg.

    @@ Mucinous cystic neoplasms (MCNs) of the pancreas are a distinct entity, account for 1% of pancreatic exocrine tumors. MCNs can be classified histologically as adenomas, borderline tumors, or carcinomas. Because several evidences showing that mucinous cystadenomas are poten- tially malignant and may transform into cystadeno- carcinomas, particularly if treated by drainage, these tumors should be identified accurately.1

    We wanted to evaluate the effectiveness of stent placement on the superior mesenteric artery as a treatment for chronic mesenteric ischemia. Seven patients (mean age: 55 years, age range: 43-66 years) with chronic mesenteric ischemia were enrolled between March 2000 and September 2003. All the patients underwent pre-procedure contrast enhanced computerized tomography to evaluate for occlusion or stenosis of the mesenteric arteries and they then underwent an angiographic procedure. A balloon-expandable metal stent was placed in the superior mesenteric artery, and this was combined with balloon angioplasty and thrombolysis. We evaluated the angiographic and procedural success after the procedures. Angiographic and procedural success was obtained in 100% of the patients and the clinical symptoms improved in 100% of the patients. The patency at 6-months and 1-year was 85% and 71%, respectively. The mean follow-up period was 12 months (range: 1-25 months). During the follow-up period, ischemic symptoms recurred in 2 patients, and restenosis in a stent was confirmed with angiography; one patient was successfully treated by stent placement in the celiac artery and the other patient died due to extensive mesenteric thrombosis. For the treatment of chronic mesenteric ischemia, percutaneous stent placement on the superior mesenteric artery showed a favorable result and it was an effective alternative to surgery for the high-risk patients.

    Our goal was to assess the value of MRA for detecting stenoses in the celiac (CA) and superior mesenteric (SMA) arteries in patients suspected of having chronic mesenteric ischemia, using an optimized systolically gated 3D phase contrast technique. In an initial study in 24 patients who underwent conventional angiography of the abdominal vessels for different clinical indications, a 3D phase contrast MRA technique (3D-PCA) was evaluated and optimized to image the CAs and SMAs. Subsequently, a prospective study was performed to assess the value of systolically gated 3D-PCA in evaluation of the mesenteric arteries in 10 patients with signs and symptoms of chronic mesenteric ischemia. Intraarterial digital subtraction angiography and surgical findings were used as the reference standard. In the initial study, systolic gating appeared to be essential in imaging the SMA on 3D-PCA. In 10 patients suspected of mesenteric ischemia, systolically gated 3D-PCA identified significant proximal disease in the two mesenteric vessels in 4 patients. These patients underwent successful reconstruction of their stenotic vessels. Cardiac-gated MRA may become a useful tool in selection of patients suspected of having mesenteric ischemia who may benefit from surgery. 16 refs., 6 figs., 4 tabs.

    Full Text Available Cavitating mesenteric lymph node syndrome (CMLNS is a rare complication of celiac disease. Globally, only 36 cases of CMLNS have been reported to date. The present article reports an incidence of its unique pathology and possible complications of celiac disease, followed by a review of the syndrome. A case involving a 51-year-old man with celiac disease who was referred to hospital because of a non-tender abdominal mass is described. Plain film x-ray of the abdomen revealed fine curvilinear calcifications in the left lower quadrant. A complex, cystic-appearing, lobulated mass with somewhat echogenic walls most consistent with calcifications was revealed on subsequent ultrasound (US imaging. Colour Doppler imaging showed no evidence of vascularity within the lesion. Computed tomography (CT imaging showed a thin rim of calcification in the walls of multiple cystic components. Enhanced magnetic resonance (MR imaging revealed a mixed solid and cystic multiloculated mass, with fat-fluid layers originating from the root of the small bowel mesentery. A CT-guided biopsy was performed. The fine-needle aspirate revealed calcified matter with no associated cellular material. No malignant cells were seen; CMLNS was established as the diagnosis. To the authors’ knowledge, there are no previous reports in the literature describing the finding of rim calcification on US or MR imaging in the setting of CMLNS. CMLNS is an important diagnosis to consider, particularly in patients with a history of celiac disease. The finding of rim calcification on US in the setting of cavitating mesenteric adenopathy should prompt further diagnostic imaging studies such as CT or MR imaging. These may lead to additional pathology studies such as a CT-guided biopsy to further characterize the lesion at the cellular level, to investigate potential malignancy and to further guide follow-up and patient management.

    Primary malignant tumors of the trachea are uncommon. The authors report a case of a 72-year-old female who died from asphyxia due to an undiagnosed obstructing adenoid cystic carcinoma of the trachea. The decedent became unresponsive while eating cereal and was pronounced upon arrival at the local hospital. The autopsy revealed a near occlusive tumor mass just superior to the bifurcation of the distal trachea. There was no evidence of aspiration. The death was the result of asphyxia due to obstruction of the trachea by an adenoid cystic carcinoma. This case demonstrates that an obstructive tumor mass may remain undiagnosed until an obstructive episode results in a sudden death.

    The posterior mediastinum is a rare site of origin for seminoma, and extensive cystic change of a seminoma is rarely observed. We present here the case of a 62-year-old male patient with a primary posterior mediastinal seminoma that was encasing the descending thoracic aorta and the tumor showed prominent cystic change on CT and MRI, and intense FDG uptake on PET/CT.

    Purpose: Mesenteric panniculitis (MP) is an underdiagnosed inflammatory condition of mesenteric adipose tissue. Prior studies suggested an association of MP with malignancy. To reassess this hypothesis, we performed the first matched case–control study comparing prevalence of malignancy and other disease in patients with and without MP. Material and methods: With a keyword search we identified CT examinations of MP patients between 2010 and 2012. Each MP patient was matched with two control patients for age, gender, abdominal diameter and CT protocol. Manifestation and extent of mesenteric panniculitis was classified independently by two investigators according to established criteria. Concomitant disease, laboratory parameters and follow up CTs were recorded and analyzed for all patients. Results: 77 of 13485 CT patients were diagnosed with MP (prevalence 0.58%). 50.6% of MP patients suffered from malignancy vs. 60.2% in the control group (p = 0.157). Over up to 4 years of follow up in 35 of these 77 MP patients no association between development of MP and the course of tumor diseases could be identified. There was also no significant difference in the rate of frequent concomitant diseases such as hypertension, diabetes or previous surgery between the two groups. Conclusion: In this first case–control-study we could show that, contrary to previous reports, mesenteric panniculitis is neither paraneoplastic nor is it associated with other diseases.

    Full Text Available Sclerosing mesenteritis is a rare benign process that involves inflammation, fat necrosis, and fibrosis of the mesentery. The disease poses great diagnostic challenge due to its nonspecific clinical and diagnostic findings. We report the case of a 75-year-old man who presented with vague abdominal discomfort associated with an intra-abdominal mass. With suspicion of a bowel carcinoid tumor on computed tomography scans, the patient underwent diagnostic laparoscopy. A diagnosis of sclerosing mesenteritis was made on histological examination. The patient's symptoms responded to a combination of immunosuppressive drugs, with no interval change in the size of the mass on radiological examination after fifteen months.

    Lymphangioma of the pancreas is an extremely rare benign turnout of lymphatic origin, with fewer than 60 published cases. Histologically, it is polycystic, with the cysts separated by thin septa and lined with endothelial cells. Though congenital, it can affect all age groups, and occurs more frequently in females. Patients usually present with epigastric pain and an associated palpable mass. Complete excision is curative, even though, depending on the tumour location, surgery may be simple or involve extensive pancreatic resection and anastomoses. The authors present a 49-year-old woman in whom a polycystic septated mass, 35 mm × 35 mm in size, was discovered by ultrasonography (US) in the body of the pancreas during investigations for epigastric pain and nausea. At surgery, a well circumscribed polycystic tumor was completely excised, with preservation of the pancreatic duct. The postoperative recovery was uneventful. Histology confirmed a microcystic lymphangioma of the pancreas. Immunohistochemistry showed cystic endothelial cells reactivity to factor Ⅷ -RA (++), CD31 (+++) and CD34 (-). Postoperatively, abdominal pain disappeared and the patient remained symptomfree for 12 mo until now. Although extremely rare, lymphangioma of the pancreas should be taken into consideration as a differential diagnosis of a pancreatic cystic lesion, especially in women.

    The purpose of our report is to illustrate an aggressive case of mesenteric fibromatosis in a 17-year-old girl with a ureteric fistula and to review imaging and pathological features, natural history and treatment options of this disease. Our patient underwent computed tomography that revealed a widespread intra-abdominal mass. The necrotic centre of this mass had a fistulous communication with the right ureter. Fibromatoses represent a spectrum of uncommon benign conditions characterised by proliferating fibrous tissue. The deep intra-abdominal form of mesenteric fibromatosis (MF), one of the rare subtypes of the 'fibromatoses' or 'desmoid tumours', grows rapidly and may become extensive. Surgery provides good results in limited disease and non-surgical modalities in cases of unresectable and residual disease.

    Mesenteric ischemia disorders are precipitated by a circulation insufficiency event that deprives one or several abdominal organs of adequate respiration to meet metabolic demands. Although mesenteric ischemia occurs infrequently, the mortality rate is from 60% to 100%, depending on the source of obstruction. The successful outcome is dependent upon a high index of suspicion and prompt management. We briefly review the pathophysiology and presentation of the various ischemic entities and review the current state of the art in diagnosis and treatment. Despite advances in both diagnosis and treatment, prompt diagnosis and supportive care remain critical for successful outcome.New imaging techniques, endovascular therapy and emerging research may improve our approach to this deadly condition.

    2009-01-01

    Mesenteric panniculitis is a rare, benign and chronic fibrosing inflammatory disease that affects the adipose tissue of the mesentery of the small intestine and colon. The specific etiology of the disease is unknown. The diagnosis is suggested by computed tomography and is usually confirmed by surgical biopsies. Treatment is empirical and based on a few selected drugs. Surgical resection is sometimes attempted for definitive therapy, although the surgical approach is often limited. We report two cases of mesenteric panniculitis with two different presentations and subsequently varying treatment regimens. Adequate response was obtained in both patients. We present details of these cases as well as a literature review to compare various presentations, etiologies and potential treatment modalities.

    Full Text Available Background. Benign cystic mesothelioma (BCM is a rare tumor that arises from the abdominal peritoneum with a predilection to the pelvic peritoneum. For this reason, it can often mimic gynecologic malignancies. Case. A 47-year-old perimenopausal female presented reporting several weeks of abdominal distention associated with abdominal tenderness and constipation. Computed tomography revealed a 24 cm multiloculated pelvic mass, and tumor markers were notable for an elevated CA-125. The patient was taken to the operating room for an exploratory laparotomy, total abdominal hysterectomy, bilateral salpingoophorectomy, and removal of pelvic mass. Final pathologic evaluation revealed a benign cystic mesothelioma. Conclusion. Classically these tumors present as large multicystic masses with thin-walled septations and on preoperative evaluation BCM can mimic many different disease entities including ovarian malignancies and cystic lymphangioma. Often diagnosis can only be made at time of surgery.

  18. Large mucinous cystic neoplasm of the pancreas associated with pregnancy

    Institute of Scientific and Technical Information of China (English)

    2008-01-01

    Mucinous cystic neoplasms (MCNs) of the pancreas occur mostly in females and are potentially sex hormone-sensitive. However, a MCN occurring during pregnancy is quite rare. A 30-year-old woman in the tenth week of pregnancy was referred to us because of a rapid increase in lett hypochondrial distending pain. On ultrasound, the patient had a large intra-abdominal cystic lesion. She was thereafter diagnosed with missed abortion and a computed tomography scan showed that the lesion was a cystic tumor 18 cm in diameter originating from the pancreatic tail. The patient subsequently underwent tumor resection with distal pancreatectomy, sparing the spleen. Histopathological analysis of the specimen revealed a pancreatic MCN with moderate dysplasia. Immunohistochemically, the tumor was positive for both estrogen and progesterone receptors. To our knowledge, this is the first reported case of pancreatic MCN with moderate zysplasia in association with pregnancy. Our case strongly indicates that pancreatic MCN is female-hormone dependent.

    62 year old Caucasian female with pancreatic head mass abutting the superior mesenteric vein (SMV) presented with fine needle aspiration biopsy confirmed diagnosis of ductal adenocarcinoma. CT scan showed near complete obstruction of portal vein and large SMV collateral development. After 3 months of neoadjuvant therapy, her portal vein flow improved significantly, SMV collateral circulation was diminished. Pancreaticoduodenectomy (PD) and superior mesenteric portal vein (SMPV) confluence resection were performed; A saphenous vein interposition graft thrombosed immediately. The splenic vein remnant was distended and adjacent to the stump of the portal vein. Harvesting an internal jugular vein graft required extra time and using a synthetic graft posed a risk of graft thrombosis or infection. As a result, we chose to perform a direct anastomosis of the portal and splenic vein in a desperate situation. The anastomosis decompressed the mesenteric venous system, so we then ligated the SMV. The patient had an uneventful postoperative course, except transient ascites. She redeveloped ascites more than one year later. At that time a PET scan showed bilateral lung and right femur metastatic disease. She expired 15 months after PD. Conclusion The lessons we learned are (1) Before SMPV confluence resection, internal jugular vein graft should be ready for reconstruction. (2) Synthetic graft is an alternative for internal jugular vein graft. (3) Direct portal vein to SMV anastomosis can be achieved by mobilizing liver. (4) It is possible that venous collaterals secondary to SMV tumor obstruction may have allowed this patient's post-operative survival. PMID:25568802

    Acute mesenteric ischemia is commonly seen in old patients. This study was undertaken to show that mesenteric ischemia might be seen in individuals under 40 years of age and that its diagnosis is challenging. Twenty-six patients with acute mesenteric ischemia under the age of 40 were studied. The main symptom on admission was abdominal pain. Symptom duration varied between 12 h and 5 days. The medical history of the patients revealed that 9 had no previous diseases. Other 17 had predisposing factors in the first evaluation. None of the patients had any history of narcotic or drug abuse. Ten patients presented with signs and symptoms of sepsis and septic shock. Preoperative diagnosis was acute intestinal ischemia only in 6 patients. Preoperatively, all the patients had intestinal or colonic ischemia and necrosis; one had additional ischemia of the liver, stomach, duodenum, and pancreas. Six patients had massive intestinal necrosis. The overall postoperative complication and overall mortality rates were 61.5 and 26.9 %, respectively. Complications and mortality were determined to be associated with previous pulmonary disease, acidosis, presence of septic shock, acute renal failure, extent of the ischemia and extent of resection, second look operations, previous cardiac events, and the kind of affected bowel (colon involvement).

    Polycythemia vera is defined as a chronic myeloproliferative disorder characterized by increased red blood cell count. There have been no reports on mesenteric thrombosis resulting from iatrogenic polycythemia. We present a patient with a history of non-small cell lung cancer undergoing maintenance oral chemotherapy on tarceva and adjunctive use of procrit. The patient presented to our emergency department with an acute abdomen and was found to have ischemic bowel from unmonitored procrit, which lead to hyperviscosity of blood and mesenteric infarction. The patient remained intubated with ventilator support. He refused a tracheostomy. He continued on feeding through the J port of the nasojejunal tube. His white cell count, and hematocrit and creatinine levels remained normal. Procrit use and chemotherapy were not restarted. He was transferred to a subacute nursing facility for further treatment. Procrit and other erythropoiesis stimulating drugs can cause significant morbidity and mortality with an increased risk of cardiovascular events, gastrointestinal bleeding, thromboembolism and stroke. This case report suggests that without closely monitoring hematocrit levels, epoetin may also be associated with an increased risk of mesenteric infarction.

    To evaluate the effectiveness of treatment options for Acute Mesenteric Ischemia and establish proper treatment guidelines. From January 2007 to May 2010, 14 patients (13 men and 1 woman, mean age: 52.1 years) with acute mesenteric ischemia were enrolled in this study. All of the lesions were detected by CT scan and angiography. Initially, 4 patients underwent conservative treatment. Eleven patients were managed by endovascular treatment. We evaluated the therapeutic success and survival rate of each patient. The causes of ischemia included thromboembolism in 6 patients and dissection in 8 patients. Nine patients showed bowel ischemia on CT scans, 4 dissection patients underwent conservative treatment, 3 patients had recurring symptoms, and 5 dissection patients underwent endovascular treatment. Overall success and survival rate was 100%. However, overall success was 83% and survival rate was 40% in the 6 thromboembolism patients. The choice of 20 hours as the critical time in which the procedure is ideally performed was statistically significant (p = 0.0476). A percutaneous endovascular procedure is an effective treatment for acute mesenteric ischemia, especially in patients who underwent treatment within 20 hours. However, further study and a long term follow-up are needed.

    A 48-year-old man presented with a 3-month history of weight loss and progressive right lower quadrant abdominal pain. His medical history was notable for appendectomy at age 17. Ultrasonography and computed tomography of the abdomen revealed a 12 cm multicystic mass in the right paracolic space. At laparotomy a large serous cyst was found arising from the lateral wall of the cecum, and four additional small cysts were found on the small bowel mesentery, greater omentum, liver capsule, and right hemi-diaphragm. Complete removal of the tumor was accomplished by right colectomy with extraperitoneal dissection of the large cyst and simple excision of the four smaller cysts. Final pathology with immunohistochemical staining confirmed cystic mesothelioma of the peritoneum. In this report we discuss the diagnostic workup and treatment of this rare disease.

    An epithelioid hemangioendothelioma is an intermediate grade tumor between hemangioma and angiosarcoma that frequently shows marked enhancement because it is a vascular tumor. Herein, we describe a rare case of a malignant epithelioid hemangioendothelioma of the femur that was mistaken as a benign lesion such as a simple bone cyst or fibrous dysplasia because the tumor had a benign cystic appearance on MRI and its imaging findings showed a histopathologic correlation.

    Fibroadenoma is the most common breast tumor in adolescent and young women. Fibroadenomas that consist of sclerosing adenosis, papillary apocrine metaplasia, epithelial calcifications, and/or cysts greater than 3 mm are considered as complex fibroadenoma. The relative risk of developing breast cancer in patients with complex fibroadenoma is increased, compared to women with noncomplex fibroadenoma. Extensive cystic degeneration in a fibroadenoma, so called "cystic fibroadenoma" is very rare. Herein, we present a case of such a lesion in a 43-year-old female who has been on follow-up for fibrocystic changes of the breast, and discuss both radiological and histopathologic differential diagnosis of this lesion with other cystic lesions of the breast, including cystic papilloma. The patient is free of disease after 17 months of clinical follow-up.

    To present a rare case of a giant schwannoma of the sacrum mimicking a Tarlov cyst. A 58-year-old woman had a 1-year history of low back pain. MRI revealed a large cystic mass in the sacral canal with bony erosion. Radiological diagnosis of Tarlov cyst was made. The patient underwent surgical treatment for the lesion, which revealed a solid mass. Histopathological examination of the tumor confirmed the diagnosis of schwannoma. The postoperative course was uneventful and the patient has had significant improvement in her pain 1 month postoperatively. Giant cystic schwannoma of the sacrum is a very rare diagnosis overlooked by practitioners for more common cystic etiologies, but its treatment is significantly different. Care should be taken to include this diagnosis in a differential for a cystic sacral mass.

    Full Text Available We hereby report an extremely unusual case of cystic angiomatous meningioma in the CPA region in a 58-year-old male patient. He presented with complaints of headache, repeated episodes of vomiting and increasing unsteadiness of gait. Neuroimaging showed a large multicystic left-sided tentorial tumor projecting into the cerebellum and CPA with contrast-enhancing peripheral solid rim. He underwent a left retromastoid craniectomy and total excision of the tumor. Histopathology revealed an angiomatous meningioma with predominant microvascular component and extensive cystic changes. Immunopositivity for epithelial membrane antigen (EMA, vimentin and S-100 protein proved vital in excluding a hemangioblastoma.

  8. Superior Mesenteric Artery Syndrome: An Infrequent Complication of Scoliosis Surgery

    Directory of Open Access Journals (Sweden)

    Metin Keskin

    2014-01-01

    Full Text Available Superior mesenteric artery syndrome is a rare condition that causes a proximal small intestinal obstruction due to contraction of the angle between the superior mesenteric artery and the aorta. Scoliosis surgery is one of the 15 reasons for superior mesenteric artery syndrome, which can present with acute or chronic manifestations. Although conservative treatment is usually possible, surgical treatment is required in certain cases that cannot be treated using conservative methods. In this paper, we describe a patient who developed superior mesenteric artery syndrome after scoliosis surgery and was treated with duodenojejunostomy due to failure and complications of conservative treatment.

    2015-12-01

    Full Text Available Multiple cystic lung disease represents a diverse group of uncommon disorders that can present a diagnostic challenge due to the increasing number of diseases associated with this presentation. High-resolution computed tomography of the chest helps to define the morphological aspects and distribution of lung cysts, as well as associated findings. The combination of appearance upon imaging and clinical features, together with extrapulmonary manifestations, when present, permits confident and accurate diagnosis of the majority of these diseases without recourse to open-lung biopsy. The main diseases in this group that are discussed in this review are lymphangioleiomyomatosis, pulmonary Langerhans cell histiocytosis and folliculin gene-associated syndrome (Birt–Hogg–Dubé; other rare causes of cystic lung disease, including cystic metastasis of sarcoma, are also discussed. Disease progression is unpredictable, and understanding of the complications of cystic lung disease and their appearance during evolution of the disease are essential for management. Correlation of disease evolution and clinical context with chest imaging findings provides important clues for defining the underlying nature of cystic lung disease, and guides diagnostic evaluation and management.

    Purpose: This study was designed to evaluate the safety of chemotherapeutic infusion or chemoembolization by way of the cystic artery in patients with hepatocellular carcinoma (HCC) supplied exclusively by the cystic artery. Methods: Between Jan 2002 and Dec 2011, we performed chemotherapeutic infusion or chemoembolization using iodized oil for the treatment of 27 patients with HCC supplied exclusively by the cystic artery. Computed tomography (CT) scans, digital subtraction angiograms, and medical records were retrospectively reviewed by consensus. Results: The cystic artery originated from the main right hepatic artery in 24 (89 %) patients, from the right anterior hepatic artery in 2 (7 %) patients, and from the left hepatic artery in 1 (4 %) patient. Selective catheterization of the cystic artery was achieved in all patients. Superselection of tumor-feeding vessels from the cystic artery was achieved in 7 patients (26 %). Chemotherapeutic infusion was performed in 18 patients (67 %), and chemoembolization was performed in 9 patients (33 %). There were no major complications and only 2 minor complications, including vasovagal syncope and nausea with vomiting. Individual tumor response supplied exclusively by the cystic artery at the follow-up enhanced CT scan were complete response (n = 16), partial response (n = 3), and stable disease (n = 8). Conclusion: HCC supplied exclusively by the cystic artery can be safely treated without severe complications by chemotherapeutic infusion or chemoembolization using iodized oil through the cystic artery.

    Non-occlusive mesenteric ischemia (NOMI) compromises all forms of mesenteric ischemia with patent mesenteric arteries. It generally affects patients over 50 years of age suffering from myocardial infarction, congestive heart failure, aortic insufficiency, renal or hepatic disease and patients following cardiac surgery. Non-occlusive disease accounts for 20-30% of all cases of acute mesenteric ischemia with a mortality rate of the order of 50%. Acute abdominal pain may be the only early presenting symptom of mesenteric ischemia. Non-invasive imaging modalities, such as CT, MRI, and ultrasound, are able to evaluate the aorta and the origins of splanchnic arteries. Despite the technical evolution of those methods, selective angiography of mesenteric arteries is still the gold standard in diagnosing peripheral splanchnic vessel disease. In early non-occlusive mesenteric ischemia, as opposed to occlusive disease, there is no surgical therapy. It is known that mesenteric vasospasm persists even after correction of the precipitating event. Vasospasm frequently responds to direct intra-arterial vasodilator therapy, which is the only treatment that has been shown to be effective. (orig.)

    Craniopharyngioma is a histologically benign and frequently cystic intracranial tumor. It may present aggressive behavior due to compression from nearby structures. Its therapeutic management is complicated because although surgery is the usual treatment of choice, it is not exempt of high morbidity and mortality and frequent tumor recurrence. In craniopharyngiomas with a significant cystic component,internal irradiation with radioactive isotopes is a therapeutic alternative to conventional treatments. We present the cases of four patients with cystic craniopharyngiomas who were treated with intracystic administration of 90Y-colloid, and their evolution after the treatment.

    2011-12-01

    Full Text Available Superior mesenteric artery syndrome is an entity generally caused by the loss of the intervening mesenteric fat pad, resulting in compression of the third portion of the duodenum by the superior mesenteric artery. This article reports the case of a patient with irremovable metastatic adenocarcinoma in the sigmoid colon, that evolved with intense vomiting. Intestinal transit was carried out, which showed important gastric dilation extended until the third portion of the duodenum, compatible with superior mesenteric artery syndrome. Considering the patient's nutritional condition, the medical team opted for the conservative treatment. Four months after the surgery and conservative measures, the patient did not present vomiting after eating, maintaining previous weight. Superior mesenteric artery syndrome is uncommon and can have unspecific symptoms. Thus, high suspicion is required for the appropriate clinical adjustment. A barium examination is required to make the diagnosis. The treatment can initially require gastric decompression and hydration, besides reversal of weight loss through adequate nutrition. Surgery should be adopted only in case of clinical treatment failure.A síndrome da artéria mesentérica superior é uma entidade clínica causada geralmente pela perda do tecido adiposo mesentérico, resultando na compressão da terceira porção do duodeno pela artéria mesentérica superior.

    Full Text Available : Teratomas are neoplasms arising from totipotent primordial cells and display a mixture of tissues of tri dermal or bi dermal origin, foreign to the anatomic site, in which they arise. [1,7] Teratomas are usually found in the sacrococcygeal area in children and gonads in adults. Less frequently they can be seen in sites such as neck, mediastinum, retro peritoneum, cranial cavity, nasopharynx and upper jaw [3, 5] . Teratomas in the gastrointestinal tract and associated organs like stomach and pancreas are rare, and there are only occasional case reports on mesenteric teratoma [3, 5] . We report a case of cystic mesenteric teratoma in a 12 year old male patient with review of relevant literature

    Decompression is considered an effective treatment for odontogenic cystic lesions in the jaw. A variety of decompression devices are successfully used for the treatment of keratocystic odontogenic tumors, radicular cysts, dentigerous cysts, and ameloblastoma. The purpose of these devices is to keep an opening between the cystic lesion and the oral environment during treatment. The aim of this report is to describe an effective decompression tube using a stainless steel tube and wire for treatment of jaw cystic lesions.

    2016-01-01

    Reports describing a rapid increase in the cystic volume of anaplastic astrocytoma (AA) in a short time frame are rare. The present study reports the case of a 68-year-old male who was admitted to the No. 9 People's Hospital, Shanghai Jiaotong University School of Medicine (Shanghai, China), with a small cystic brain lesion and positive immunological testing for cysticercosis. Head magnetic resonance imaging (MRI) showed a cystic lesion, 6 mm in diameter, in the left frontal lobe. Neurocysticercosis was suspected and the patient was treated with a clinical trial of albendazole and steroids. A period of 25 days later, the patient's condition had deteriorated, and MRI revealed a cystic lesion in the left frontal lobe; thereafter, the cystic lesion was removed and a diagnosis of AA was established. The tumor was soft, ivory white and gelatinous due to myxoid degeneration. In this case, tumor-related angiogenesis and microvascular extravasation (blood-brain barrier disruption) may have been the main cause of the rapid increase in the cystic volume in such a short time frame. The similarity of the glioma and cysticercus antigens may have been the cause of the positive reactions in the cystic fluid. The present study reports the rare occurrence of a rapid increase of cystic volume and potential diagnostic difficulties. PMID:27698865

    Large cystic masses originating from the retroperitoneal space are rare, and cystic tumors are often considered preferentially in the differential diagnosis. However, it is difficult to make a correct diagnosis. A 55-year-old man presented with a palpable abdominal mass. A computed tomography (CT) scan detected a mass mimicking a large cystic tumor in the retroperitoneal space anterior to the psoas muscle. The mass had an enhanced outer margin, an irregular inner margin, and several surrounding necrotic lymph nodes. However, histopathologic examination followed by an exploratory laparotomy confirmed that the mass was consistent with a tuberculous (TB) abscess. A retroperitoneal TB abscess without spinal or active pulmonary TB is very rare. To the best of our knowledge, there are no published reports of a retroperitoneal TB abscess confirmed by both CT scan and surgical pathology in the Korean literature. We report a rare case of a huge retroperitoneal TB abscess that can mimic a cystic tumor.

    Full Text Available Cystic fibrosis (CF is one of the most frequent inherited mortal diseases in Caucasian population. Dysfunction in exocrine glands is described in CF patients, with severe pancreatic insufficiency and chronic lung disease. CF is inherited as an autosomal recessive disorder. More than 1000 disease-associated mutations in the cystic fibrosis transmembrane conductance regulator (CFTR gene have been described. DF508 mutation is the most common mutation in the CF gen. Diagnosis in CF is based on clinical and laboratory tests findings. Meconial ileus, CF in other relatives, chronic lung disease, congenital absence of the vas deferens with azoospermia are among other clinical findings, main criteria in CF patients. Two positive results in sweat chloride test , or demonstration in nasal epithelial ionic transport alteration (nasal potential difference and identification of two CF mutations in the patient are laboratory findings in CF.

    A cystic lymphangioma arising within the abdomen is a rare entity in children. It may present with an abdominal mass and symptoms of abdominal pain, vomiting, and anorexia. These nonspecific clinical symptoms are often attributed to more common acute pediatric conditions. In this report, we describe two pediatric cases of intra-abdominal cystic lymphangioma that were initially diagnosed and treated as appendicitis. True diagnosis was only achieved on surgical excision and pathological investigation of cystic material.

    The improvement over the last two decades in the treatment of cystic fibrosis led to an increase in life expectancy approaching 40 years at birth. Logically, the population of adult patients has been increasing and is currently 50% of patients followed in France. These therapeutic advances have justified the establishment in 2003 of a generalized neonatal screening for cystic fibrosis. The latest data of this screening show an incidence of CF of 1/5359 live births, far below the incidence of 1/2500 which was widely accepted twenty years ago. The performance of this screening is currently based on the dosage of trypsin immuno reactive, followed in case of exceeding the threshold of a search of the 30 most common mutations, can detect around 96% of 150 to 200 CF cases every year. Therefore, the possibility of a false negative of the screening cannot be excluded and evocative symptoms of cystic fibrosis, even for children born after 2003, will lead to prescribe a sweat test. While treatments available so far goal consequences of cystic fibrosis, a new therapeutic class to correct the functional defect of the mutated protein, called CFTR modulators, is emerging. Ivacaftor, leader of this new class, belonging to the category of "CFTR potentiator" got its access on the market in September 2012 for patients carrying the G551D mutation. New other molecules, named "CFTR correctors" which can have synergistic effect with ivacaftor and concern patients carrying the most common mutation--DF 508--are under development. Copyright © 2013.

    Pylephlebitis--suppurative thrombophlebitis of the portal and/or mesenteric veins--is a rare complication of abdominal infections, especially diverticulitis. It can lead to severe complications such as hepatic abscess, sepsis, peritonitis, bowel ischemia, etc., which increase the mortality rate. Here we present a case of suppurative thrombophlebitis of the inferior mesenteric vein, as a complication of sigmoid diverticulitis. The epidemiology, clinical and radiological features as well as treatment strategies are discussed. We also review the anatomy of the mesenteric vein given its anatomic variation in the present case and how this anatomic knowledge might influence the operative approach should surgery be necessary.

    Full Text Available Mesenteric venous thrombosis is a rare cause of abdominal pain, which if left untreated may result in bowel infarction, peritonitis and death. The majority of patients with this illness have a recognizable, predisposing prothrombotic condition. Oral contraceptives have been identified as a predisposing factor for mesenteric venous thrombosis in reproductive-aged women. In the last fifteen years new methods of hormonal birth control have been introduced, including a transdermal patch and an intravaginal ring. In this report, we describe a case of mesenteric venous thrombosis in a young woman caused by a vaginal contraceptive ring. [West J Emerg Med. 2014;15(4:395-397.

    This unit describes a recommended approach to identifying causal genetic variants in an individual suspected of having cystic fibrosis. An introduction to the genetics and clinical presentation of cystic fibrosis is initially presented, followed by a description of the two main strategies used in the molecular diagnosis of cystic fibrosis: (1) an initial targeted variant panel used to detect only the most common cystic fibrosis-causing variants in the CFTR gene, and (2) sequencing of the entire coding region of the CFTR gene to detect additional rare causal CFTR variants. Finally, the unit concludes with a discussion regarding the analytic and clinical validity of these approaches.

    Full Text Available The Primary central salivary gland neoplasms of the mandible are infrequent. Their clinical and radiographic features may be similar to odontogenic tumors, which are otherwise common. Their accurate diagnosis becomes troublesome.Hence, diagnosis should depend on stringent diagnostic criteria. Adenoid cystic carcinoma is well known for its prolonged clinical course and its tendency for delayed onset of distant metastases. The long-term survival of these patients is therefore poor. Treatment modalities include surgery, radiotherapy and chemotherapy. The purpose of this paper is to report a case of primary central adenoid cystic carcinoma of mandible with an atypical presentation.

    A case of chondroblastoma in an 18-year-old female arising from a rib near the costotransverse articulation (presumably from the epiphysis of the articular process) has been described. The destructive pattern noted in the rib, associated with a large soft tissue mass, favored a malignant lesion rather than a benign one. Histologically, this tumor had large cystic and hemorrhagic components, consistent with the diagnosis of a cystic chondroblastoma of a rib. Curiously, this patient, like two others with chondroblastoma in a rib was asymptomatic, and attention to the abnormality was drawn from a routine chest radiography. The patient remains disease-free one and a half-years following surgery.

They are most commonly diagnosed in young children. Nearly 90% are apparent by the age of 2 years. Here, we reporting a case of 20-year-old female presented with gradually increasing painless swelling in the upper outer quadrant of her left breast for 1½ years. Mammography of the breast showed multiple irregular hypoechoic lesions associated with irregular duct dilatation. Lumpectomy was performed and diagnosed as cystic lymphangioma. Complete excision is the treatment of choice.

    Abdominal leiomyosarcoma arising from the mesentery is a rare malignancy. It is an aggressive entity with an overall 5 year survival rate between 20 and 30 %. Surgical resection is the cornerstone of primary treatment and may be curative for localized disease. However, patients often develop intra-abdominal relapse and/or metastatic disease. If surgical resection is not feasible, palliative chemotherapy is the treatment of choice. However, there are no clear guidelines regarding chemotherapy; neither in the adjuvant nor advanced setting. We present a 40 year-old woman, with a mesenteric leiomyosarcoma, who underwent radical tumor resection and did not receive adjuvant oncological therapy. Three months postoperatively, she developed metastatic disease to the lungs and liver. After multidisciplinary assessment she received an unconventional histological-subtype-tailored chemotherapy comprising 3-4 regimens. Initially, there was a decrease both in number and size of metastases. Ultimately, an almost complete radiological response was seen. Subsequent surgical resection and radiofrequency ablation of residual metastatic foci in the liver and lung brought her into complete clinical remission. She is presently tumor free, 36 months following diagnosis of metastatic disease. To our knowledge, this is the first report of a patient with metastatic mesenteric leiomyosarcoma who is in complete clinical and radiological long-term remission following very aggressive multimodal treatment; including intense poly-drug chemotherapy and without any demonstrable long-term side effects. Given the rarity of mesenteric leiomyosarcoma and lack of guidelines regarding oncological therapy, we suggest that multimodal therapy including aggressive chemotherapy, guided by a multidisciplinary team, is essential to achieve an optimal outcome.

In nineteen humans, superior mesenteric and coeliac artery flows were determined by duplex ultrasonography during fasting and postprandial submaximal cycling and compared with the splanchnic...... blood flow as assessed by the Indocyanine Green dye-elimination technique. 3. Cycling increased arterial pressure, heart rate and cardiac output, while it reduced total vascular resistance. These responses were not altered in the postprandial state. During fasting, cycling increased mesenteric, coeliac...... and splanchnic resistances by 76, 165 and 126 %, respectively, and it reduced corresponding blood flows by 32, 50 and 43 % (by 0.18 +/- 0.04, 0.42 +/- 0.03 and 0.60 +/- 0.04 l min-1). Postprandially, mesenteric and splanchnic vascular resistances decreased, thereby elevating regional blood flow, while...

  14. A case of follicular lymphoma complicated with mesenteric panniculitis

    2009-11-01

    Full Text Available Mesenteric panniculitis (MP is a rare disease occasionally complicated with lymphoma. A 55-year old female presented with MP accompanied by malignant lymphoma. This patient was first treated for follicular lymphoma and subsequently for panniculitis. After 6 courses of R-CHOP chemotherapy, the treatment response was partial. An additional course of salvage chemotherapy led to a complete response. Since the mesenteric mass progressed simultaneously with the regression of other lymphoma lesions, we performed a biopsy of the mesenteric mass and pathologically confirmed an MP lesion without lymphoma. Subsequent high-dose chemotherapy led to CR and the MP lesion remained stable. In the present case, MP progressed with chemotherapy. We concluded that mesenteric lesions suspected of progressing or recurring should be diagnosed pathologically even if asymptomatic.

    We illustrate the sonographic findings of malignant breast masses that can mimic a cystic component with pathologic correlations. The disease entities presented in this study include infiltrating ductal carcinoma, ductal carcinoma in situ (DCIS), papillary carcinoma, mucinous carcinoma, medullary carcinoma, metaplastic carcinoma, and a malignant phyllodes tumor. Malignant masses with a cystic component are often characterized by well-circumscribed round, oval, or lobular masses, thereby appearing benign on ultrasonography. On pathology, the cystic component of a malignant mass is identified by cystic degeneration, hemorrhage, necrosis, or ductal dilatation. If the mass is well-circumscribed with a cystic component, a biopsy should be considered in the analysis of the solid component within a mass.

    We experienced a case of intussusception caused by cystic lymphangioma of the colon in a 32 years old female who was admitted to our hospital for the chief complaint of bloody stool. In the colonoscopic examination,cystic mass with stalk which had smooth mucosal surface was noted at the descending colon. Abdominal ultrasonography and computed tomography revealed left colon intussusception with a multilocular cystic tumor as a leading point. Emergent operation was performed. On the histopathologic examination, the cystically dilated spaces lined by endothelium and septated by fibrous septa were present. The pathological diagnosis was cystic lymphangioma of the colon. Although intussusception due to lymphangioma in an adult are rare, it should be taken into consideration that it is possible diagnosis.

    2008-01-01

    Solid-pseudopapillary tumor (SPT) is a rare neoplasm of the pancreas that usually occurs in young females.It is generally considered a low-grade malignant tumor that can remain asymptomatic for several years.The occurrence of infiltrating varieties of 5PT is around 10%-15%.Between 1986 and 2006,282 cystic tumors of the pancreas were observed.Among them a SPT was diagnosed in 8 patients (2.8%) with only one infiltrating variety.This was diagnosed in a 49-year-old female 13 years after the sonographic evidence of a small pancreatic cystic lesion interpreted as a pseudocyst.The tumor invaded a long segment of the portalmesenteric vein confluence,and was removed with a total pancreatectomy,resection of the portal vein and reconstruction with the internal jugular vein.Histological examination confirmed the R-0 resection of the primary SPT,although a vascular invasion was demonstrated.The postoperative course was uneventful,but 32 mo after surgery the patient experienced diffuse liver metastases.Chemotherapy with different drugs was started.The patient is alive and symptom-free,with stable disease,75 mo after surgery.Twenty-five patients with invasion of the portal vein and/or of mesenteric vessels were retrieved from the literature,16 recent patients with tumor relapse after potentially curative resection were also retrieved.The best treatment remains a radical resection whenever possible,even in locally advanced or metastatic disease.The role of chemotherapy,and/or radiotherapy,is still to be defined.

    To describe the epidemiological, physiopathological, clinical and therapeutic knowledge concerning cystic fibrosis (CF). Important modifications in the health organization of the care concerning this orphan disease have been implemented in France. The life expectancy has dramatically increased, as well as the knowledge concerning the pathological structure and function of the CFTR gene and protein. This will lead to the development of emerging drug treatments for this lethal disease. The life expectancy is predicted to exceed 40 years for children born in the 2000s. As a result, there has been a tremendous growth of the adult population that reached 40% of the overall approximately 5000 patients included in the CF French registry (Observatoire National de la Mucoviscidose). Lung disease remains the primary cause of morbidity and mortality. The characteristic phenotypic presentation associates bronchial and rhinosinusal symptoms, pancreatic insufficiency and liver disease. Bronchial damage leads to progressive chronic respiratory insufficiency. Diabetes mellitus and osteoporosis frequently appears in adulthood. Neonatal screening has been implemented in France since 2002. It will prevent delayed diagnosis and its deleterious consequences. Some atypical cases of CF presenting only with one or two organ system involvement can be diagnosed in adulthood. Isolated chronic rhinosinusitis, bronchiectasis, congenital bilateral absence of vas deferens, recurrent pancreatitis, allergic bronchopulmonary aspergillosis, and some case of cholangitis may so revealed late form of cystic fibrosis. The health care is organized in cystic fibrosis centres. Despite gene discovery, treatment still remains symptomatic, based on intensive pulmonary and nutritional treatments. Challenges for new treatments are to correct the basic defect, either by gene therapy or by pharmacological modulation of the abnormal physiological processes.

  1. Incidental finding of malignant renal cystic tumour diagnosed sonographically

    2008-01-01

    Full Text Available Introduction Malignant cystic renal tumor is a rare variant of renal malignancy. Cystic neoplasm results from haemorrhage, necrosis and colliquation of a solid tumour or tumour occurring within the wall of a cyst. That pathoanatomic substratum reflects characteristic sonographic features indicating its malignant nature. It is important to distinguish a simple cyst (not requiring surgery from intracystic malignant lesion because it requires surgery. Case Outline The authors present a 59-year-old woman with a sonographic finding of a simple cyst in the upper pole of the right kidney revealed during gynaecological ultrasonography. Immediately afterwards, the radiologist performed renal sonography and its finding was a cystic lesion suggestive of malignancy. Further evaluation by CT scan showed that the lesion was clearly malignant. After surgery, the histological finding verified cystic renal cancer. Conclusion Ultrasonography may reveal a complex cyst and solid mass but requires an experienced sonographer. Contrast CT scan would be performed to examine the "suspicious" lesion because it clearly shows if a cystic lesion is benign or malignant. .

    Benign multicystic peritoneal mesothelioma (BMPM) is a rare disease with good short-term prognosis and rare malignant transformation. However, its biological significance remains unexplained. A neoplastic origin is considered by many authors to require a surgical excision, based on the high recurrence and progressive growth rate of the tumors. However, alternative or integrative treatment options have also been proposed. A 45-year-old woman presented to our unit with a history of occasional discomfort and pain in the left hip. On physical examination, we noticed a tough-elastic, fixed mass located in the iliac fossa. Computed tomography scan detected a mass with multiseptated cystic-like areas. Due to the similarity of these findings to a primitive sarcomatous tumor of the retroperitoneum, an arteriographic study was also performed. The patient underwent en bloc resection of the mass, including a segment of the sigmoid colon. The final pathologic diagnosis was cystic mesothelioma. Further studies are needed to better understand the etiology and pathogenesis of this rare disease, and to define a more tailored treatment plan.

    Sleep disturbances are frequently observed in cystic fibrosis (CF). The resultant sleep fragmentation, short sleep duration, and gas-exchange abnormalities are postulated to contribute to the neurocognitive, cardiovascular, and metabolic abnormalities associated with CF. There are no outcomes data to establish the optimal procedure for screening and treating CF patients for sleep-related respiratory abnormalities. Therapy with supplemental oxygen and bilevel ventilation are widely considered to be effective in the short term, but there are few evidence-based data to support long-term improvements in morbidity and mortality.

    We report a case of massive cystic pyeloureteritis that had been diagnosed by ureterorenoscopy in a patient with recurrent urinary infection and episodes of nephritic colic. The reports published in the literature indicate there is no specific treatment for this disease whose etiology is unknown. Its pathogenesis has not been well-established and it is difficult to distinguish from other urothelial filling defects. Although it has also been reported that it may progress to malignancy, we believe that the therapeutic approach should be conservative.

  5. Usefulness of 320-Row Area Detector Computed Tomography for the Diagnosis of Cystic Falx Meningioma

    Full Text Available We present a case of cystic falx meningioma. Cystic meningioma is rare and not easy to diagnose preoperatively; it is often misdiagnosed as other tumors, including glial or metastatic tumors with cystic or necrotic changes. This study showed the potential impact of 320-row computed tomography (CT on image-based diagnostic evaluation of cystic meningioma with special attention to the novel techniques of 4-dimensional CT angiography (4D-CTA and CT whole-brain perfusion (CTP. 4D-CTA showed the arterial supply feeding the tumor and late enhancement of the tumor nodule, similar to that seen in meningioma by conventional angiography. CTP showed that the tumor had a higher cerebral blood flow and cerebral blood volume and a longer mean transit time than adjacent brain tissue. These findings were consistent with meningioma and reinforced the other imaging findings, resulting in the correct preoperative diagnosis. The new techniques available for 320-row CT can potentially be used to improve differential diagnosis and preoperative assessment of cystic tumors with nodules.

    The goal of this study was to perform a retrospective analysis of the ultrasonographic findings associated with low-grade endometrial stromal sarcoma. Ten pathologically confirmed cases of low-grade endometrial stromal sarcoma at our institution from January 2007 to April 2014 were retrospectively reviewed. All patients underwent a preoperative transvaginal ultrasound. Two radiologists came to a consensus regarding the location, size, margin, and echogenicity of the tumor, as well as the presence of intratumoral cystic degeneration and its extent and configuration. Low-grade endometrial stromal sarcoma manifested as an intramural mass protruding into the endometrial cavity (n=6) or as a purely intramural mass (n=4). The maximal diameter of the lesion ranged from 4 to 9.1 cm (mean, 6.2 cm). The imaging features of low-grade endometrial stromal sarcoma were variable: six cases involved predominantly solid masses containing cystic degeneration, one was a predominantly unilocular cystic mass, two were ill-defined infiltrative solid masses, and one was a well-defined solid mass. Among the seven cases with internal cystic degeneration, five patients showed a multiseptated cystic area or a cystic area with multiple small clusters, while a unilocular cystic area within the tumor was found in two patients. Low-grade endometrial stromal sarcoma is associated with variable ultrasonographic findings with regard to the location, margin, and configuration of the lesion. Multiseptated cystic areas and multiple small areas of cystic degeneration are common.

    A 52-year-old man presented with recurrent postprandial abdominal pain, sitophobia, and progressive weight loss. Chronic mesenteric ischemia (CMI) due to subtotal occlusion of the superior mesenteric artery (SMA) and flush occlusion of the celiac artery (CA) was diagnosed. Retrograde recanalization of the CA by way of a collateral channel from the SMA was performed using contemporary recanalization equipment. The CA and SMA were then stented, resulting in sustained resolution of CMI-related symptoms.

    Purpose: To describe the spectrum of early CT findings of lupus mesenteric vasculitis (LMV) and to assess the utility of CT in the management of this uncommon entity. Methods: Abdominal CT was performed within 1-4 days (average 2.2 days) of the onset of severe abdominal pain and tenderness in 15 women with systemic lupus erythematosus. Prompt high-dose i.v. corticosteroid in 11 patients after the CT diagnosis of LMV was made. CT was performed after abdominal symptoms subsided. Results: Eleven cases revealed CT features suggestive of LMV including conspicuous prominence of mesentric vessels with palisade pattern or comb-like appearance (CT comb sign) supplying focal or diffuse dilated bowel loops (n=11), ascites with slightly increased peritoneal enhancement (n=11), small bowel wall thickening (n=10) with double halo or target sign (n=8). Follow-up CT before high-dose steroid therapy revealed complete or marked resolution of the abnormal CT findings. Conclusion: CT is helpful for confirming the diagnosis of LMV, especially the comb sign which may be an early sign. Bowel ischemia due to LMV is less ominous than previously expected, and the abnormal CT findings were reversible when early diagnosis and prompt i.v. steroid therapy could be achieved. (orig.).

  11. Adenoid cystic carcinoma of the lacrimal sac: case report

    Antonio Ramos

    Full Text Available ABSTRACT Lacrimal sac tumors are rare with a clinical presentation that typically includes obstruction of the lacrimal drainage system and epiphora as the most frequent symptom. Cribriform adenoid cystic carcinoma (ACC is the most common malignant epithelial tumor of the lacrimal gland and minor salivary glands; however, its occurrence in the lacrimal drainage apparatus is extremely rare. Given the rarity of ACC, definitive diagnosis is almost invariably late conferring a poor prognosis. Herein we report the case of a 41-year-old woman with primary ACC of the lacrimal sac and describe the ophthalmological examination, diagnosis, and multidisciplinary treatment of this rare type of tumor.

    Mesenteric fibromatosis (MF) is a rare tumor (2-4 cases per 1 million people annually) with few presented features. In this case study, we reported five MF patients, one of whom suffered a recurrence. Patients received renogram, colonoscopy, cystoscopy, and gastrointestinal examinations. Histology and immunohistochemistry evaluations were performed after the surgical resection. Hormone levels were measured before and after the surgery. It was found that clinical imaging readily confirmed an abnormal mass but was unable to distinguish MF from other tumors. Histology and immunohistochemistry were definitive diagnoses because the tissue was vimentin ± β-catenin ± CD117-/CD34-. Furthermore, the patient who suffered a recurrence showed an elevated estrogen level. A 6-month postoperative administration of letrozole drove the estrogen down to normal level. Our study showed that vimentin, β-catenin, CD117, and CD34 were the markers for MF whereas medical imaging, and estrogen level could be used for the complimentary purpose.

    We herein describe the case of a 27-year-old female, who presented with a large mass of the upper left abdominal cavity discovered incidentally, through an annual health examination. Preoperative studies including abdominal ultrasonography and magnetic resonance imaging were performed, but they could not accurately determine the nature of the tumor. At laparotomy, a large cystic tumor of the small bowel mesentery was found. Histopathologic examination diagnosed the tumor as a cystic lymphangioma.Although lymphangiomas are rare, especially in the abdomen of adults, they may sometimes present as acute abdomen,causing complications that require emergent surgery.

    Diagnosis of cystic lesions of the pancreas is made by clinical history taking, physical examination, blood biochemical tests and diagnostic imaging, such as transabdominal ultrasound, endoscopic ultrasound (EUS), cross-sectional imaging (computed tomography and/or magnetic resonance imaging) and endoscopic retrograde cholangiopancreatography, bearing in mind the known characteristic features of the various cystic lesions that can occur in this organ. Among others, EUS, endowed with a sharp local resolving power, has been described as a highly useful examination method, because it enables concurrent fine-needle aspiration (FNA). EUS has an important role in the differential diagnosis and tumor grading (benign, premalignant or malignant) of cystic lesions. Although the differential diagnosis of cystic lesions of the pancreas based on EUS morphology is practicable to some extent, there have also been reports showing that the diagnosis might vary with the endosonographer and that the diagnostic performance of this method for tumor grading is not necessarily high. In countries overseas, differential diagnosis and tumor grading of cystic lesions of the pancreas are actively undertaken not merely by EUS morphology, but also by cyst-fluid EUS-guided FNA (EUS-FNA) cytology and measurements of pancreatic enzymes and tumor markers, and importance is attached to EUS-FNA in the latest version of the American Society for Gastrointestinal Endoscopy Guideline and in the diagnostic strategies for cystic diseases of the pancreas. Meanwhile, the current Japanese consensus is that EUS-FNA is not recommended in cases of mucinous cystic lesions suspected as being intraductal papillary mucinous neoplasm or mucinous cystic neoplasm.

    The importance of maintaining adequate nutrition in patients with cystic fibrosis has been well known for the past 3 decades. Achieving normal growth and maintaining optimal nutrition is associated with improved lung function. Comprehensive and consistent nutritional assessments at regular intervals can identify those at risk of nutritional failure and uncover micronutrient deficiencies contributing to malnutrition. Management of malnutrition in cystic fibrosis should follow a stepwise approach to determine the causes and comorbidities and to develop a nutritional plan. Nutritional management is crucial at every stage in a person's life with cystic fibrosis and remains a cornerstone of management.

    Objectives: To compares the effectiveness and impact of high inferior mesenteric artery (IMA) versus low IMA ligation on 5-year survival, lymph node yield rates, and peri-operative morbidity and mortality. Methods: The databases of Educational Resources Information Centre (ERIC), the Web of Science, EBSCO and MEDLINE were searched using MeSH terms ‘colorectal cancer’, ‘inferior mesenteric artery’, ‘high ligation’, ‘low ligation’, ‘mesenteric lymph nodes’, ‘prognosis’, and ‘survival’. Only clinical studies were selected and review articles and meta-analysis were excluded. In cases of duplicate cohorts, only the latest article was included. Irrelevant articles and the articles on both right and left sided CRC were excluded. The finally selected studies were analysed for the defined end-point outcomes. Results: The published data has shown that high IMA ligation improves the yield of harvested lymph node that allows accurate tumor staging and a more reliable estimation of prognosis. High ligation was not found to be positively correlated with increased anastomotic leakage or impaired genito-urinary function. However, high ligation demands advanced surgical expertise and longer operating time. There was no significant difference in 5-year survival rates for both techniques. Some studies have reported fatal complications of high ligation such as proximal bowel necrosis. Conclusion: Although there is no consensus, this research signals the routine use of high ligation for left-sided CRC. However, the published fatal complications following high ligation and no significant difference in 5-year survival rates demand more studies to establishing a unified protocol. PMID:27381531

    Toxic factors released from the intestine have been implicated in the pathophysiology of severe acute illness, including acute pancreatitis, trauma and hemorrhagic shock, and burns. Toxic factors in mesenteric lymph may induce an inflammatory systemic response while bypassing the portal circulation and liver. This paper reviews current knowledge of the anatomy, physiology and pathophysiology of mesenteric lymph and focuses on factors influencing its composition and flow, and potential therapeutic interventions. A search of the Ovid MEDLINE database up until the end of January 2006 yielded 1,761 relevant publications, the references of which were then searched manually to identify further related publications. A wide range of factors potentially affecting mesenteric lymph flow and composition were identified. Targeted interventions have been similarly broad, including medical therapy, nutritional support and surgery. Of the available surgical interventions, thoracic duct external drainage has been the most widely studied. This systematic review highlights significant gaps in our present understanding of the role of mesenteric lymph in health and disease. Further research is needed to identify factors responsible for the generation of biologically active mesenteric lymph, the role of agents modulating its flow and composition, the importance of intrinsic pump activity, the potential therapeutic role of lipophilic antioxidant agents, the comparative effects of low-fat enteral nutrition and standard enteral nutrition, and the therapeutic outcomes of thoracic duct ligation versus thoracic duct external drainage.

    Full Text Available It was generally believed that Cystic fibrosis (CF is rare among Arabs; however, the few studies available from Egypt and other Arabic countries suggested the presence of many undiagnosed patients. The aim of the present study was to determine the frequency of CF patients out of the referred cases in a single referral hospital in Egypt. A total of 100 patients clinically suspected of having CF were recruited from the CF clinic of the Allergy and Pulmonology Unit, Children’s Hospital, Cairo University, Egypt, throughout a 2 year period. Sweat chloride testing was done for all patients using the Wescor macroduct system for collection of sweat. Quantitative analysis for chloride was then done by the thiocyanate colorimetric method. Patients positive for sweat chloride (⩾60 mmol/L were tested for the ΔF508 mutation using primer specific PCR for cystic fibrosis transmembrane conductance regulator (CFTR gene. Thirty-six patients (36% had a positive sweat chloride test. The main clinical presentations in patients were chronic cough in 32 (88.9%, failure to thrive in 27 (75%, steatorrhea in 24 (66.7%, and hepatobiliary involvement in 5 (13.9%. Positive consanguinity was reported in 50% of CF patients. Thirty-two patients were screened for ΔF508 mutation. Positive ΔF508 mutation was detected in 22 (68.8% patients, 8 (25% were homozygous, 14 (43.8% were heterozygous, and 10 (31.3% tested were negative. CF was diagnosed in more than third of patients suspected of having the disease on clinical grounds. This high frequency of CF among referred patients indicates that a high index of suspicion and an increasing availability of diagnostic tests lead to the identification of a higher number of affected individuals.

    Primary cystic pancreatic neoplasms are rare tumors, with an approximate prevalence of 10% of cystic pancreatic lesions. Most of these lesions correspond to mucinous cystic neoplasm, serous cystoadenoma and intraductal papillary mucinous tumor (IPMT). IPMT is characterized by diffuse dilatation of the main pancreatic duct and/or side branches with inner defects related to mucin or tumor, or mucin extrusion from a patent ampulla. IPMT has a low potential for malignancy, with a low growth rate, a low rate of metastatic spread and postsurgical recurrence. Over the last few years, major advances have been made in the diagnostic and therapeutic management of this tumor.

    This article is intended as a brief practical guide for physicians and physiotherapists concerned with the treatment of cystic fibrosis. Physiotherapeutic techniques for the treatment of chest diseases have been developed and modified as advances have taken place in the medical management of cystic fibrosis. The article describes forced expiratory technique, positive expiratory pressure, postural drainage, autogenic drainage and other techniques. Patients with cystic fibrosis live longer and have a better quality of life than ever before, but progressive deterioration of lung function will always be their most serious problem. Physical activity and chest physiotherapy are essential parts of all treatment regimens for cystic fibrosis. It is important to realize that the physiotherapist is a very important member of the team which includes nurses, physicians-and the patient.

    A study was conducted on labial salivary gland tumors from four oral pathology laboratories. Of the 103 identified tumors, 87 (84.5%) were from the upper lip, whereas 16 (15.5%) were from the lower lip. Of the 87 upper lip tumors, 80 (92.0%) were benign. Forty-three of these were monomorphic adenomas and 37 were pleomorphic adenomas. Seven malignant tumors of the upper lip were as follows: four adenoid cystic carcinomas, two acinic cell carcinomas, and one adenocarcinoma. Of the 16 lower lip tumors, 15 (93.8%) were malignant. Thirteen of these were mucoepidermoid carcinomas and two were acinic cell carcinomas. The only benign lower lip tumor was an intraductal papilloma. These results confirm the findings of previous investigations, showing that minor salivary gland tumors are much more common in the upper lip than the lower lip, but that lower lip tumors are more likely to be malignant.

    The migration of [125I]UdR-labelled mesenteric lymph node cells in NIH strain mice at various times after inis produced an enhanced accumulation of mesenteric immunoblasts in the small intestine at 2 and 4 days after infection but not at later times. The enhanced migration occurred when using cells from both uninfected and infected donors, denoting an absence of antigenic specificity. This effect is not secondary to a reduced arrival of cells at sites away from the gut in infected mice, but to a primary increase of the arrival in the small intestine. Mesenteric T lymphoblasts (separated on a nylon-wool column) migrated to the small intestine of uninfected recipients and appear to be a major portion of the population which migrate to the gut of infected recipients. Our results were confirmed using 51Cr to label mesenteric cells. We conclude that the parasite causes the small intestine to become more attractive or retentive for mesenteric blast cells early during infection.

    Acute dissection of the thoracic aorta is a well-recognized, often fatal condition that frequently extends to involve the abdominal aorta and iliac vessels. The ostia of the renal and mesenteric vessels may be compromised, and the resulting visceral ischemia may necessitate surgical intervention. However, visceral perfusion may be restored if blood flow from true to false lumen is re-established or if the false lumen is obliterated, either spontaneously or by surgical or interventional techniques. Isolated dissections of mesenteric, renal, and carotid vessels are rarely reported. These may be spontaneous, related to high blood pressure and underlying disease of the vessel wall, or caused by abdominal trauma or medical intervention, including angiographic procedures. They are usually associated with pain and other signs and symptoms of ischemia in the appropriate territory. We present a case of chronic superior mesenteric artery (SMA) dissection, an incidental angiographic finding, in an asymptomatic patient being evaluated for resection of an abdominal aortic aneurysm (AAA).

    Superior mesenteric artery (SMA) aneurysms represent a minority of visceral aneurysms but may result in lethal complications if left untreated. Options for treatment include aneurysmorraphy, bypass, ligation, or embolization. Here we present a case of a man with a history of celiac graft thrombosis who presents with a recurrent symptomatic SMA aneurysm. Given his compromised celiac axis, ligation was not an option. His SMA aneurysm was repaired with a PTFE patch. However, to secure longstanding blood flow to the small bowel in the event of graft thrombosis, the distal SMA pedicle was dissected free of the ileocolic vessels and anastomosed to the aorta. Follow-up studies demonstrated an occluded PTFE patch with a patent SMA autotransplant. This case depicts a novel approach to the surgical management of complex recurrent SMA aneurysms.

    Mesenteric vascular insufficiency is a serious medical condition that may lead to bowel infarction, morbidity, and mortality that may approach 50%. Recommended therapy for acute mesenteric ischemia includes aspiration embolectomy, transcatheter thrombolysis, and angioplasty with or without stenting for the treatment of underlying arterial stenosis. Nonocclusive mesenteric ischemia may respond to transarterial infusion of vasodilators such as nitroglycerin, papaverine, glucagon, and prostaglandin E1. Recommended therapy for chronic mesenteric ischemia includes angioplasty with or without stent placement and, if an endovascular approach is not possible, surgical bypass or endarterectomy. The diagnosis of median arcuate ligament syndrome is controversial, but surgical release may be appropriate depending on the clinical situation. Venous mesenteric ischemia may respond to systemic anticoagulation alone. Transhepatic or transjugular superior mesenteric vein catheterization and thrombolytic infusion can be offered depending on the severity of symptoms, condition of the patient, and response to systemic anticoagulation. Adjunct transjugular intrahepatic portosystemic shunt creation can be considered for outflow improvement. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer-reviewed journals and the application of well-established methodologies (RAND/UCLA Appropriateness Method and Grading of Recommendations Assessment, Development, and Evaluation or GRADE) to rate the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where evidence is lacking or equivocal, expert opinion may supplement the available evidence to recommend imaging or treatment. Copyright © 2017 American College

  16. Cystic lung disease: Achieving a radiologic diagnosis

    Diffuse cystic lung disease represents a diverse group of uncommon disorders with characteristic appearance on high resolution CT imaging. The combination of imaging appearance with clinical features and genetic testing where appropriate permits a confident and accurate diagnosis in the majority of the diseases without recourse for open lung biopsy. The mechanism of cyst development disease is unclear but in some disorders appears to be related to small airways obstruction. These diseases are incurable, with the exception of Langerhans cell histiocytosis which may spontaneously remit or resolve on smoking cessation. Disease progression is unpredictable; in general older patients have a more benign disease, while young patients may progress rapidly to respiratory failure. An understanding of the complications of cystic lung disease and the appearance of disease progression is essential for the management of these patients. A number of these disorders are associated with malignancy, recognition of the potential tumors permits appropriate imaging surveillance. Due to the widespread use of CT, pulmonary cysts are increasingly discovered incidentally in an asymptomatic individual. The diagnostic challenge is to determine whether these cysts represent an early feature of a progressive disease or have no clinical significance. In the elderly population the cysts are unlikely to represent a progressive disease. In individuals <50 years further evaluation is recommended.

    2006-01-01

    A 45-year-old man, with a previous history of astrocytoma, presented with diffuse abdominal pain. A CT scan was non-specific and the pain worsened; his abdomen became peritonitic on examination. An exploratory laparotomy was performed, and a large small bowel mesenteric mass was found together with an associated haematoma. Subsequent histology showed the tumour to be a benign fibromatosis, and the patient recovered uneventfully. There were no reports in the literature of any association between astrocytomas and fibromatosis. Mesenteric fibromatosis is a rare tumour often associated with Gardner's syndrome. It can present in a multitude of ways and the only definite treatment is surgical resection.

    Mesenteric lipoma is an extremely rare disease in children. Fewer than 50 cases have been reported in the literature. Diagnosis is based on clinical examination, ultrasound, and computed tomography (CT). However, only the histological study of the specimen during laparotomy or laparoscopy can confirm the diagnosis. Thus, surgery, be it by laparotomy or laparoscopic, is both a means of exploration and treatment in mesenteric lipoma. We report on a case of giant lipoma of the mesentery in a 7-year-old girl presenting paroxysmal abdominal pain with a subocclusive syndrome lasting 1 week.

    A 73-year-old man with pre-existing cardiac failure, coronary artery and chronic obstructive pulmonary disease was presented for an acute mesenteric ischaemia, resulting from an embolic obstruction of the superior mesenteric artery. An intra-arterial fibrinolysis with a bolus of 250 000 units of streptokinase, followed by an infusion of 150 mg rtPA with adequate heparin dosage was performed 10 hours after the first symptoms. An abdominal guarding occurred 24 hours later, despite radiological improvement, justifying emergency surgery which confirmed the partial efficiency of the medical therapy. Unfortunately, a cardiogenic shock occurred preoperatively and the patient died five days later from intractable cardiovascular failure.

    Superior mesenteric artery (SMA) arising from aorta at the level of first lumbar vertebra usually takes an angular downward course from ventral surface of aorta. It is through this vascular angle that the 3rd part of duodenum passes at the level of 4th lumbar vertebra. Fat and lymphatics around SMA maintains the angle at 25° to 60° with a mean of 450 and provide protection against duodenal compression. In Superior Mesenteric Artery Syndrome, the SMA-aorta angle in narrowed down to 7° to 22° w...

    Purpose: To characterize cystic pancreatic lesions and tumors with magnetic resonance imaging (MRI), and to assess the value of morphological criteria in differentiating pseudocysts versus cystic tumors and benign versus malignant cystic tumors. Material and Methods: Twenty-three patients with cystic pancreatic tumors or lesions underwent plain and contrast-material-enhanced MRI, including magnetic resonance cholangiopancreatography (MRCP). The MR findings were characterized and analyzed by two readers, and the role of various imaging criteria and combinations thereof for final lesion assignment were assessed. Final diagnoses were obtained from the results of open surgery (n = 19) and/or biopsy (n = 4). Results: Final diagnoses included cystic tumors (n = 11) and pseudocysts (n = 12). The lesions were located in the head (56%) and body or tail (44%). Lesion diameters ranged from 7 to 50 mm. Various lesion contrast enhancement patterns were observed for both benign and malignant lesions. Serous cystadenomas were located in the head, they were lobulated, and had wall diameters >2 mm; with the combination of these characteristics all patients with serous cystadenoma could be identified, whereas in no other patient was this constellation observed. Conclusion: MRI facilitated the diagnosis of serous cystadenomas, although no definite morphologic criterion for the differentiation between pseudocysts and mucinous cystadenomas was identified. In consideration of the substantial therapeutic consequences, either diagnostics in unclear cystic pancreatic lesions should comprise cyst fluid analysis if necessary, or eligible patients should be referred for surgical resection.

    Thrombophlebitis occurs secondarily to inflammatory conditions of adjacent organs, and radiologic finding is essential for diagnosis. However, because of the rarity on clinical cases that involve the inferior mesenteric vein, many radiologists are unfamiliar with its location and appearance. We experience a case of septic thrombophlebitis with abscess complication sigmoid diverticulitis. CT scans reveals a low density thrombus and air in the inferior mesenteric vein, combining with perivascular fat infiltration, and focal wall defects with abscess formation. After surgical treatment, the abscess was not visible in the follow-up CT scans. Septic thrombophlebitis of the inferior mesenteric vein, although being a rare disease, should be diagnosed on CT according to the given unique location, the appearance of inflamed vein and the adjacent descending mesocolon.

    A case of so-called "papillary and cystic neoplasm of the pancreas" (PCNP) was reported and investigated immunohistochemically and ultrastructurally. A tumor of the pancreatic head in a 21-year-old female was curatively resected. The tumor was cystic and histologically consisted of uniform cells in papillary and solid structure. Although there was no immunoreactivity for pancreaticogut hormones or secretory products of the pancreas in the tumor cells, most of the tumor cells were diffusely immunoreactive for neuron-specific enolase (NSE). Some neurosecretory granules were detected in the tumor cells ultrastructurally. Both facts suggested endocrine cell character of the tumor. Certain cases of PCNP might show a differentiation to endocrine cells.

    We present computed tomography findings of three cases of intraperitoneal rupture of ovarian mature cystic teratoma. Acute-phase radiological findings include presence of intraabdominal liquid, infiltration of mesenteric fat and calcified pelvic mass which also showed interior fatty content. Chronic-phase findings include infiltration of peritoneal fat, as well as increase in the size of adjacent ganglion due to chronic inflammatory response to histologically verified foreign bodies. Differential diagnoses between chronic and acute intraperitoneal ruptures of mature teratoma have been reviewed. (Author)

    To characterize the radiological and clinicopathologic features of cystic synovial sarcoma. Seven patients with primary cystic synovial sarcoma were evaluated. Computed tomography (CT) and magnetic resonance (MR) imaging were undertaken at the first presentation. The diagnosis of synovial sarcoma was made on the basis of histological examinations followed by molecular analysis. Radiological and clinicopathologic findings were reviewed. CT showed well-defined soft tissue mass without cortical bone erosion and invasion. Calcification was seen at the periphery of the mass in three cases. T2-weighted MR images showed multilocular inhomogeneous intensity mass in all cases, five of which showed fluid-fluid levels. On gross appearance, old and/or fresh hematomas were detected in six cases. In the one remaining case, microscopic hemorrhage in the cystic lumen was proven. Four cases had poorly differentiated areas. In five cases prominent hemangiopericytomatous vasculature was observed. Histologic grade was intermediate in one tumor and high in six. One case had a history of misdiagnosis for tarsal tunnel syndrome, one for lymphadenopathy, two for sciatica and two for hematoma. All cystic synovial sarcomas demonstrated multilocularity with well-circumscribed walls and internal septae. Synovial sarcoma should be taken into consideration in patients with deeply situated multicystic mass with triple signal intensity on T2-weighted MR imaging. (orig.)

    The purpose of this study is to analyze the CT features of the cystic masses in the neck and to review differential diagnosis. We retrospectively reviewed and analyzed the CT findings of 22 histopathologically proved, cystic neck masses in regard to the location in fascial plane and relationship with adjacent organ. Of 22 cases, ten congenital cysts two ranulas, seven inflammatory lesions, and three solid tumors were included. Ten congenital cystic masses were located in typical locations as branchial cleft cyst (5) in mandibular angle, thyroglossal duct cyst (3) in visceral space embeded within the strap muscles, cystic hygroma (1) and cavernous hemangioma (1) in posterior cervical space with insinuating appearance. Two cases of ranula included one simple ranula localized in sublingual space and a plunging ranula extending to adjacent submandibular space. Seven cases of inflammatory lesions were characterized by multispatial locations and good contrast-enhancement of walls and adjacent tissue. Solid masses of low density mimicking cyst were two pleomorphic adenomas of submandibular gland and one neurilemmoma. It is considered that thorough analysis of the CT findings with attention to typical location, CT appearance, and the relationship with the adjacent structures usually leads to the correct diagnosis.

    To describe CT findings and differential points of cystic thymic lesions. We evaluated retrospectively total 19 masses with well marginated cystic lesions at thymic area on CT scans. They were 10 teratomas, 3 congenital thymic cysts, 2 multilocular thymic cysts(associated with thymoma and myasthenia gravis in each), 2 cysts Assciated with thymic Hodgkin's lymphomas an ectopic parathyroid cyst, and an infected thymic cyst. The radiological abnormalities evaluated were thickness of the wall, presence or abscene of septa, mural nodule, solid component, calcification and fat component. All three cases of congenital thymic cysts and an ectopic parathyroid cyst appeared as thin-walled unilocular cyst with homogeneous internal density and without identifiable solid component. In multilocular thymic cyst, there were thick wall and solid components(n =2), thick internal septa and calcifications(n = 1). The cysts of teratomas manifested thick walls(n = 9), internal septa(n = 4), calcifications(n = 6), fat components(n = 4), and solid components(n = 4). Cysts in Hodgkin's diseases appeared as multilocular or unilocular and had thick wall and septa without calcification. Infected thymic cyst presented with multilocular cystic mass with identifiable wall and septa, calcification, and solid components. The thymic diseases with cystic lesion include teratomas, congenital thymic cysts, multilocular thymic cysts, parathyroid cyst, and Hodgkin's disease. Congenital thymic cyst and ectopic parathyroid cyst are thin-walled unilocular cystic lesions. Cystic lesions associated with teratoma, Hodgkin's disease, and multilocular thymic cyst are thick-walled cystic lesions with or without solid component.

    AIM: To recognize cystic neoplasia of the pancreas and thus to identify a panel of curable diseases. METHODS: Sixty-four cases of cystic neoplasia of the pancreas, including 28 cases of intraductal papillary mucinous neoplasia (IPMN), 12 Cases of serous cystic neoplasia (SCN), 11 cases of mucinous cystic neoplasia (MCN), 11 cases of solid pseudo-papillary neoplasia (SPN), and 2 cases of solid tumor with cystic degeneration were examined immunohistochemically for their expression of MUC1, MUC2, MUC4, MUC5AC, and MUC6, as well as other related antigens.RESULTS: Adenoma type of IPMN and borderline lesions exhibited high expressions of MUC2, and MUCSAC. Tn contrast, IPMN with invasive carcinoma component showed MUC1 immunoreactivity. SCN was mainly positive for MUC1 and MUC6, while negative for MUC2, MUC4 and MUC5AC. Noninvasive MCN, regardless of its cellular atypia degree, was positive for MUC5AC and negative for MUC1. MUC1 expression was only observed in patients with an invasive component. No mucin expression was found in SPN.CONCLUSION: Mucin profile may, in conjunction with histologic study, provide important information on tumor types and patient treatment of cystic neoplasia of the pancreas.

  11. The Changing Spectrum of Surgically Treated Cystic Neoplasms of the Pancreas

    Jennifer K. Plichta

    2015-01-01

    Full Text Available Introduction. While the incidence of pancreatic cystic lesions has steadily increased, we sought to evaluate the changes in their surgical management. Methods. Patients with pancreatic cystic lesions who underwent surgical resection from 2003 to 2013 were identified. Clinicopathologic factors were analyzed and compared to a similar cohort from 1992 to 2002. Results. There were 134 patients with pancreatic cystic lesions who underwent surgical resection from 2003 to 2013, compared to 73 from 1992 to 2002. The most common preoperative imaging was a CT scan, although 66% underwent EUS and 63% underwent biopsy. Pathology included 18 serous, 47 mucinous, 11 pseudopapillary, and 58 intraductal papillary mucinous neoplasms (IPMN. In comparing cohorts, there were significantly fewer serous lesions and more IPMN. Postoperative complication rates were similar, and perioperative mortality rates were comparable. Conclusion. There has been a dramatic change in surgically treated pancreatic cystic tumors over the past two decades. Our data suggests that the incorporation of new imaging and diagnostic tests has led to greater detection of cystic tumors and a decreased rate of potentially unnecessary resections. Therefore, all patients with cystic pancreatic lesions should undergo a focused CT-pancreas, and an EUS biopsy should be considered, in order to best select those that would benefit from surgical resection.

    Pulmonary cystic echinococosis, a zoonosis caused by the larvae of the dog tapeworm Echinococcus granulosus, is considered as a major public health problem in those countries where dogs are used to care for large herds because of the incapacitating effects produced in affected population. The ratio lung:liver involvement is higher in children than in adults. A higher proportion of lung cases are discovered incidentally on a routine x-ray evaluation; the majority of infected people remain asymptomatic until the cyst enlarges sufficiently to cause symptoms. The majority of symptoms are caused by mass effect from the cyst volume; the presence of complications caused by cysts broke changes the clinical presentation; the principal complication is cyst rupture, producing cough, chest pain, hemoptysis, or vomica. Diagnosis is obtained by imaging evaluation (Chest X-ray or CT scan), supported by serology in the majority of cases. Surgery is the main therapeutic approach, having as principal objective, the removal of the parasite, preventing intraoperative dissemination; the use of pre surgical chemotherapy reduces the chances of seeding and recurrence; treatment using benzimidazoles is the preferred treatment when surgery is not available, or complete removal is not feasible PMID:20216420

    It has been well known that angiosarcoma (AS), particularly scalp AS, metastasizes to the lungs with multiple air-filled cystic lesions on chest computed tomography scans. Pneumothorax, due to cystic lesion rupture into the pleural space, is frequent;however, we do not exactly know how rapidly the metastatic lesions spread to the lungs or what the exact pathogenetic mechanism for cystic metastasis is. According to our experience, the speed of disease progression in pulmonary metastasis is relatively fast and the entire lungs may be involved within two or three months. The infiltrating spindle cell tumors in the alveolar walls are tethering the adjacent alveolar spaces in order to form a dilated air-filled cystic lesion.

    Schwannomas are slowly growing, well capsulated, benign tumors. Involvement of vestibular nerve is most commonly followed by trigeminal nerve. Trigeminal schwannoma is rare entity, and cystic degeneration with intraorbital extension of trigeminal schwannoma is even rarer. These tumors occur in fourth and fifth decades of life and patients have variable presentation depending on which cranial compartment is involved. Orbital schwannoma usually presents with proptosis with or without vision loss. We are reporting such a rare case of solid cystic trigeminal schwannoma with intraorbital extension through superior orbital fissure that was removed surgically. PMID:27695572

    2015-11-01

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

    Chronic mesenteric ischemia (CMI) is a rare disorder that is commonly caused by progressive atherosclerotic stenosis or occlusion of one or more mesenteric arteries. Endovascular treatment for symptomatic CMI represents a viable option, especially in high-operative risk patients. We report a case of acute symptomatic CMI with chronic totally occlusion of the superior mesenteric artery (SMA) associated with significant stenosis of celiac trunk (CT) and inferior mesenteric artery (IMA) that underwent endovascular treatment of all the three mesenteric arteries: stenting of CT and IMA stenosis, and recanalization of the SMA occlusion by retrograde crossing via the Villemin arcade.

About 60% of these cysts occurs before 5 years of age and can be located anywhere in the gastrointestinal tract, but are most often found in the small bowel mesentery. The clinical presentation depends on the location and size of the cyst and many cases are asymptomatic and are diagnosed incidentally. The most common symptoms are abdominal pain, bloating, abdominal mass, nausea, vomiting, constipation, diarrhea, weight loss, fever and peritonitis. Complications include torsion, infarction, volvulus formation, perforation, infection, anemia, intracystic hemorrhage, intestinal obstruction and obstructive uropathy. They are typically treated by simple excision, marsupialization or segmental bowel resection and have excellent long-term prognosis.

    Non-cystic fibrosis bronchiectasis (NCFB) is an increasingly prevalent disease that places a significant burden on patients and health systems globally. Although many of the therapies used to treat NCFB were originally developed as cystic fibrosis (CF) therapies, not all of them have been demonstrated to be efficacious in NCFB and some may even be harmful. This article explores the evidence for which therapeutic strategies used to treat CF have been translated into the care of NCFB. The conclusion is that therapies for adult NCFB cannot be simply extrapolated from CF clinical trials, and in some instances, doing so may actually result in harm.

    Mesenteric vessels, including the superior mesenteric artery (SMA) and vein (SMV), provide and drain the rich blood supply of the midgut and hindgut. SMA and SMV injuries are rare and often lethal. Clinical management of these injuries is not well established, but treatment options include operative, non-operative, and endovascular strategies. A narrative review of the literature was conducted using MEDLINE Complete-EBSCO. Relevant studies, specifically those focusing on diagnosis and management of SMA and SMV injuries, were selected. Only original reports and collected series were selected to prevent duplication of cases. A search of the literature for mesenteric arterial injuries yielded 87 studies. Vessel-specific breakdown of the studies yielded 40 with SMA injuries and 41 with SMV injuries. These searches were winnowed to 26 individual studies, which were included in this collective review. Limitations of this study are similar to all narrative literature reviews: the dependence on previously published research and availability of references as outlined in our methodology. Although historically rare, mesenteric vessel injuries are seen with increasing incidence and continue to present a challenge to trauma surgeons due to their daunting mortality rates. Currently, universal treatment guidelines do not exist, but the various options for their management have been extensively reviewed in the literature.

    A report is given on the treatment planning by computed tomography and monitoring in 37 cases of preponderantly cystic craniopharyngiomas with different solid tumor parts. Colloidal yttrium 90 silicate was used for the intracystic contact irradiation. Two pretherapeutic forms of the solid tumor parts were found in CT examination which correlated with different courses: 1. the polymorphic type and 2. the type with a smooth outline. A posttherapeutic decrease of the cystic volume was observed in 74% of type 1 cases (n=19) and in 89% of type 2 cases (n=18). An increase in volume was only found in type 1 (21%). An increase of the solid tumor part was also found exclusively in the polymorphic type (68%). An additional external irradiation should be considered for this CT manifestation of the tumor, as the solid tumor part is not exposed in intracystic contact irradiation.

    Cystic lymphangioma is an uncommon benign developmental tumor of the lymphatic system, seen rarely in adults. A 23-year-old man visited DKUDH complaining of the painless swelling in the right submandibular triangle area. It was reported that swelling had increased since 5 months ago. Clinically, fluctuant and mobile mass was palpated at the right submancivular area. CT scan showed a large, well-defined, homogenous low density mass, measuring 5.0X2.5X4.0 cm. T1W MRI scan demonstrated a large, multiseptated homogenous low signal mass with septum and rim enhancement. Proton-density and T2W MRI scan showed mass of high signal intensity. MRI scan was able to delineate better the enhanced multiseptation and extent of the lesion. Histopathologically, a lobulated cystic mass lined by a layer of flattened endothelium was observed.

    Neonatal orchitis is an extremely rare disease, usually related to a congenital genitourinary anomaly. We present a 36 weeks' gestation infant who presented at 3 days old with a firm and enlarged right testicle. Testicular US revealed a heterogeneous right testicle with numerous cystic spaces as well as decreased testicular blood flow. The clinical concerns included testicular tumor and cystic dysplasia of the testis because of concurrent renal dysplasia. The scrotal/testicular area was without tenderness or overlying erythema. Radical inguinal orchiectomy revealed diffuse gram-negative orchitis.This case represents an atypical presentation of orchitis. This entity should be added to the differential diagnoses of testicular mass in the neonate even in the absence of physical findings suggestive of infection.

    We report a case of retroperitoneal cystic lymphangioma in a 30-year-old woman who presented with abdominal distention and pain. Imaging studies revealed a large, thin-walled multicystic mass occupying the whole abdomen. Based on a preoperative diagnosis of multicystic mesothelioma, we performed laparotomy, which revealed a tumor arising from the gastropancreatic ligament in the posterior wall of the omental bursa. We resected the tumor completely, without the adjacent viscera. The final pathological diagnosis was cystic lymphangioma, based on the immunohistochemical findings of positive CD31 and CD34 expression, the presence of smooth muscle confirmed by smooth muscle antigen and desmin, and negative calretinin, WT-1 and cytokeratins 5/6 expression. Multicystic mesotheliomas and cystic lymphangiomas are so similar in morphology that immunohistochemical staining should be fully utilized to differentiate them.

    Full Text Available Context Solid and cystic papillary neoplasm of the pancreas is an extremely rare neoplasm that mostly affects young females in the mean age of 25 years and accounts for about 0.2-2.7% of all pancreatic tumors. Case report A 18-year-old female presented with progressively increasing mass in the left hypochondrium and epigastric regions and vague abdominal pain. There was no history of jaundice and vomiting. The mean diameter of the tumors was 17x24 cm. Preoperative core needle revealed solid and cystic papillary neoplasm. Distal pancreatectomy and splenectomy were performed. The patient did not receive adjuvant therapy and no tumor recurrence was detected in follow up. Conclusion Solid and cystic papillary neoplasm may reach large dimensions with a benign behavior and is curable by surgical excision. Differential diagnosis from other tumors with aggressive behavior is therefore important.

    Cystic fibrosis (CF) patients may require frequent courses of antibiotics and repeated hospital admissions. Although children with CF have high carriage rate for C.difficile, they rarely develop colitis. Pseudomembranous colitis is more common in adult post lung transplant CF patients. Although rare, paseudomembranous colitis should be considered in CF patients presenting with abdominal symptoms even in the absence of diarrhoea.

    2014-06-01

    We present the recent therapeutic advances in the cystic fibrosis care. It concerns improvements in symptomatic treatment with the development of dry powder inhaled antibiotics that improved quality of life, and innovative treatments namely the modulators of the cystic fibrosis transmembrane protein conductance regulator (CFTR), molecules which act specifically at the level of the defective mechanisms implied in the disease. The life expectancy of cystic fibrosis patients born after 2000, is estimated now to be about 50 years. This improvement of survival was obtained with the organization of the care within the specialized centers for cystic fibrosis (Centre de ressource et de compétences de la mucoviscidose) and remains still based on heavy symptomatic treatments. Dry powder inhaled antibiotics constitute a significant time saving for patients to whom all the care can achieve two hours daily. Since 2012, the modulators of CFTR, molecules allowing a pharmacological approach targeted according to the type of the mutations, allows a more specific approach of the disease. Ivacaftor (Kalydeco(®)) which potentialises the function of the CFTR protein expressed on the cellular surface is now available for patients with the G551D mutation. Lumacaftor is going to be tested in association with ivacaftor in patients with the F508del mutation, that is present in at least 75% of the patients. The ataluren which allows the production of a functional protein CFTR in patients with a no sense mutation is the third representing of this new therapeutic class. We presently have numerous symptomatic treatments for the cystic fibrosis care. The development of CFTR modulators, today available to a restricted number of patients treated with ivacaftor represents a very promising therapeutic avenue. It will represent probably the first step to a personalized treatment according to CFTR genotype. Copyright © 2013 Société nationale française de médecine interne (SNFMI). Published by

    Background Gastrointestinal stromal tumours (GIST) usually present with non-specific gastrointestinal symptoms such as abdominal mass, pain, anorexia and bowel obstruction. Methods We report a case of a 42 year old male who presented with a solitary intracranial space occupying lesion which was established as a metastasis from a mesenteric tumour. Results The patient was initially treated as a metastatic sarcoma, but a lack of response to chemotherapy prompted testing for CD117 which returned positive. A diagnosis of mesenteric GIST presenting as solitary brain metastasis was made, and the patient was treated with imatinib. Conclusion We recommend that all sarcomas with either an intraabdominal or unknown origin be routinely tested for CD117 to rule out GIST. PMID:17105654

    Lower gastrointestinal hemorrhage accounts for approximately 20% of gastrointestinal hemorrhage. The most common causes of lower gastrointestinal hemorrhage in adults are diverticular disease, inflammatory bowel disease, benign anorectal diseases, intestinal neoplasias, coagulopathies and arterio-venous malformations. Hemangiomas of gastrointestinal tract are rare. Mesenteric hemangiomas are also extremely rare. We present a 25-year-old female who was admitted to the emergency room with recurrent lower gastrointestinal bleeding. An intraluminal bleeding mass inside the small intestinal segment was detected during explorative laparotomy as the cause of the recurrent lower gastrointestinal bleeding. After partial resection of small bowel segment, the histopathologic examination revealed a cavernous hemagioma of mesenteric origin. Although rare, gastrointestinal hemangioma should be thought in differential diagnosis as a cause of recurrent lower gastrointestinal bleeding. PMID:19178725

  1. Autobuttressing of colorectal anastomoses using a mesenteric flap.

    Mohan, H M

    2013-12-01

    Anastomotic leakage is a common and dreaded complication of colorectal surgery. Many different approaches have been tried to attempt to reduce leakage and associated morbidity. The concept of reinforcement of an anastomosis by buttressing is well established. Techniques described include using sutures, native omentum, animal or synthetic material. We report a technique for buttressing using a mesenteric flap to envelope the anastomosis. The primary rationale is to reduce clinical sequelae of anastomotic leakage by promoting local containment, as well as providing a scaffold for healing. Using autologous tissue provides a safe, time-efficient and cost-effective buttress without the risks of infection or reaction associated with foreign material. A mesenteric flap is particularly useful in patients in whom omentum is not available due to previous surgery, or to fill the dead space posterior to a low anastomosis within the pelvis.

    Mesenteric traction syndrome consists of cutaneous hyperemia with hypotension and tachycardia. NSAIDs could inhibit the phenomenon, but there are few reports about when to administer these drugs. In this study, we evaluated the effect of indomethacin on preventing mesenteric traction syndrome when administered preoperatively and just after induction of anesthesia. Thirty-six patients scheduled for abdominal hysterectomy were studied. Patients were randomized into three groups. Group C (n = 12); control, group T (n = 12); indomethacin 50 mg suppository just after induction of anesthesia, group P (n = 12); indomethacin 50 mg suppository about 90 min before incision. The effect of indomethacin was evaluated from the extent of cutaneous hyperemia. MTS was suppressed in group P, but not in group T (P traction syndrome.

    2015-12-01

    Pancreaticoduodenectomy (PD) is considered one of the most challenging abdominal operations for several reasons, including the anatomy, which is surrounded by vital vascular structures and also because of the serious complications that are possible in the postoperative period. Nowadays, thanks to the development of minimally invasive surgery and improvement of patients' selection, laparoscopic pancreatic resections have been proven to be technically feasible and safe especially in the case of left pancreatectomies. More recently, many series of laparoscopic PD for adenocarcinoma have been published demonstrating the feasibility of this technique. In pancreatic cancer, the advantage of superior mesenteric artery "first approach" is already known to achieve an oncological resection. The purpose of this video is to describe the different technical aspects of the laparoscopic superior mesenteric artery first approach in the right posterior fashion.

    2012-02-03

    Three patients were referred to a national neurosurgical centre following CT evidence of subarachnoid haemorrhage. The three patients, who were referred from different institutions within a seven week period, were Fisher grade 3 and WFNS Grade I at all times. Angiography showed a PCOM aneurysm in one case, a ruptured Basilar tip aneurysm and an unruptured ACOM aneurysm in another case, and an ACOM aneurysm in the third case. It was decided that the aneurysms were suitable for endovascular coiling. These patients had unremarkable intraoperative catheterizations and coiling but subsequently deteriorated post-operatively due to mesenteric ischaemia. Two patients required colectomy for mesenteric ischaemia, and the third arrested secondary to sepsis from bowel perforation. We discuss the various causes that may explain this association, and we alert the neurosurgical community for this complication which has not been reported before.

    The bowel and the mesentery represent the third most frequently involved structures in blunt abdominal trauma after the liver and the spleen. Clinical assessment alone in patients with suspected intestinal and/or mesenteric injury from blunt abdominal trauma is associated with unacceptable diagnostic delays. Multi-detector computed tomography, thanks to its high spatial, time and contrast resolutions, allows a prompt identification and proper classification of such conditions. The radiologist, in fact, is asked not only to identify the signs of trauma but also to provide an indication of their clinical significance, suggesting the chance of conservative treatment in the cases of mild and moderate, non-complicated or self-limiting injuries and focusing on life-threatening conditions which may benefit from immediate surgical or interventional procedures. Specific and non-specific CT signs of bowel and mesenteric injuries from blunt abdominal trauma are reviewed in this paper.

    O' Connor, Donal B

    2010-12-03

    Abstract Introduction Benign cystic mesothelioma or peritoneal inclusion cysts are rare benign abdominal tumors usually occurring in females of reproductive age. These cysts present as abdominopelvic pain or masses but are often found on imaging or incidentally at surgery. They are commonly associated with pelvic inflammatory disease, endometriosis, or ovarian cysts. We report what is, to the best of our knowledge, the first case of a benign cystic mesothelioma complicating a presentation of acute appendicitis. Case Presentation A 19-year-old Irish Caucasian woman presented with abdominal pain. Imaging suggested appendicitis with abscess formation. She was treated with antibiotics and scheduled for interval appendicectomy. At laparoscopy, an unusual cystic mass was found arising from the appendix. Histology revealed benign cystic mesothelioma. Conclusion We report what is, to the best of our knowledge, the first case of a benign cystic mesothelioma arising from the appendix and complicating a presentation of acute appendicitis. This is a benign pathology, but recurrences are not uncommon. Benign cystic mesothelioma should be included in the differential when investigating pelvic masses or abscesses associated with either appendicitis or pelvic inflammatory disease in women.

    To investigate the characteristics of papillary thyroid carcinoma (PTC) with cystic changes visible on ultrasonography (US). This study included 553 PTCs in 553 patients between January 2003 and August 2004. One radiologist with 10 years of experience in thyroid imaging retrospectively reviewed the preoperative US images. Two different groups were formed according to two different reference points (group 1, 25%; group 2, 50%) of the cystic component. Patients between the groups were compared according to their clinicopathologic characteristics. Disease-free survival (DFS) was estimated. Cox's multivariate proportional hazards regression model was used to identify the effect of variable factors on the recurrence risk. Fifty-six patients (10.1%) were confirmed to have tumor recurrence within the follow-up period. Thirty-five patients had regional metastasis, one had distant metastasis, eight had multiple site metastases, and 12 had biochemical recurrence. PTC patients with a ≤ 50% or PTC patients with a ≤ 25% cystic component did not have a statistically significant longer DFS than those with a >50% (hazard ratio [HR], 1.118; 95% confidence interval [CI], 0.255 to 4.910; P=0.883) or those with a >25% cystic component (HR, 0.569; 95% CI, 0.164 to 1.976; P=0.375), respectively. Moreover, independent predictors of recurrence were pathologic size, male gender, and lymph node metastasis, not a >50% or >25% cystic component. The proportion of the cystic component in PTCs did not affect DFS.

    Full Text Available Although the exact prevalence of cystic pancreatic lesions is unknown, it is estimated to be around 1% of the general population based on large scale observational imaging studies [1]. While cystic pancreatic lesions are increasingly diagnosed due to the widespread use of cross-sectional imaging modalities like computed tomography (CT and magnetic resonance imaging (MRI, it is not known if this reflects a true increase in incidence [1]. Inflammatory pseudocysts constitute about 75% of pancreatic cysts but are not classified as true cystic pancreatic lesions since they are non-epithelial inflammatory fluid collections associated with acute or chronic pancreatitis [2]. About 15% of cystic pancreatic lesions can be classified as cystic neoplasms that require further evaluation and monitoring due to risk of progression to malignancy [1, 3]. Based on surgical pathology, cystic pancreatic lesions are classified by the type of epithelium lining the cyst. These include serous cystadenomas, intraductal papillary mucinous neoplasms (IPMN, mucinous cystadenomas, mucinous cystadenocarcinomas, solid pseudopapillary tumors and few other rare types [4].

    Oncogenesis of anaplastic carcinoma of the pancreas is a subject of controversy, because it shows sarcomatous nature with extremely poor prognosis. We herein report an unusual case of anaplastic carcinoma occurring with a recurrent mucinous cystic neoplasm in a 38-year-old female. A 10-cm retroperitoneal cystic mass was pointed out in the first pregnancy and a probable diagnosis of mucinous cystic neoplasm was made in October 2000. She refused surgery first and delivered her baby uneventfully. During her second pregnancy in 2002, however, she presented hematemesis and underwent urgent distal pancreatectomy, splenectomy and partial resection of the gastric wall where the tumor perforated. A diagnosis of borderline-type mucinous cystic neoplasm with ovarian-like stroma was made. Nine months later, CT visualized a recurrent cystic tumor near the pancreatic stump, which was subsequently resected. Pathology revealed that the tumor was composed of two different components of borderline-type mucinous cystic neoplasm and anaplastic carcinoma. The latter was intensely positive for vimentin, CD68, p53 and focally for cytokeratin, suggesting both sarcomatous and carcinomatous differentiation. She survived four years after the second surgery without tumor recurrence. Although the origin of anaplastic carcinoma has not been determined yet, it should be remembered that anaplastic carcinoma can occur in association with mucinous cystic neoplasm of more benign histology.

  13. Early intestinal perforation secondary to congenital mesenteric defects

    Full Text Available Gastrointestinal perforation (GIP in preterm neonates may be idiopathic, due to necrotizing enterocolitis (NEC, or mechanical obstruction. The predominant cause of GIP in the neonatal period is NEC. Differential diagnosis with congenital malformations, including mesenteric defects leading to internal hernias, is mandatory if the onset is early. We describe two newborns with trans-mesenteric herniation resulting in GIP, and we discuss the presence of possible additional risk factors such as prematurity and predisposing vascular disruption in connective tissue disorders (Ehlers-Danlos syndrome, twinning, and use of assisted reproductive technologies. These cases prompted us to review our exploratory laparotomies performed for intestinal obstruction, complicated/or not with perforation, to identify the frequency of neonatal trans-mesenteric hernias in a referral hospital. The prevalence of GIP and of internal hernia was 25% and 3.3%, respectively. In conclusion, time-onset and particular conditions associated with GIP should lead to a high index of suspicion for internal hernias in order to achieve appropriate diagnosis and therapy.

    To report on the safety and efficacy of superselective transcatheter arterial chemoembolization(TACE) of tumor feeding branches originating from the cystic artery for the treatment of hepatocellular carcinoma(HCC). From, May 1955 to, September 1999, eleven HCC patients aged between 38 and 82 (mean, 57.4) years with tumor-feeding branches originating from the cystic artery underwent TACE. In eight, for whom superselection of these branches was possible, TACE was done with the use of Gelform and a mixture of Lipiodol and cisplatin, while for three, for whom superselection was impossible, a mixture of Lipiodol and cisplatin only was used. Immediately after TACE, remnant tumor staining was angiographically evaluated, and tumor response was determined by follow-up CT at one month. After procedure, the development of cholecystitis was clinically. Post-FACE angiography showed remnant tumor staining in one patients who underwent embolization with Gelform and the mixture fo Lipiodol and cisplatin, and in one for whom the mix ture of Lipodol and cisplationly was used. Among the eight for whom Gelfoam and the mixture of Lipiodol and cisplatin was used, one-month follow up CT showed compact Lipiodol uptake in five, partial Lipiodol uptake in three, no change in tumor size in six, increased tumor size in one, and decreased tumor size in one. Among the three for whom the mixture of Lipiodol and cisplatin only was used,one-month follow-up CT showed neither Lipiodol uptake nor change in tumor size in one patient, partial Lipiodol uptake and increased tumor size in one, and compact Lipiodol uptake and decreased tumor size in one. Cholecystitis developed in only one patient who underwent embolization with Gelfoam and the mixture of Lipiodol and cisplatin, but was cured by conservative treatment. Superselective TACE of tumor feeding branches originating from the cystic artery seems to be a safe and effective method for the treatment of hepatocellular carcinoma.

    Cystic fibrosis is a life-limiting, recessive disease caused by mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene. Increased survival outcomes and the multisystem nature of the disease, including the involvement of hepatobiliary and gastrointestinal tracts, now require the need for more extensive knowledge and expertise in cystic fibrosis among gastroenterologists. Manifestations are either a direct consequence of the primary defect in cystic fibrosis or a secondary complication of the disease or therapy. Adult patients with cystic fibrosis also have an increased risk of malignancy in the gastrointestinal and pancreatico-biliary tracts compared with the general population. Novel treatments that target the basic defects in the CFTR protein have emerged, but to date not much is known about their effects on the gastrointestinal and hepatobiliary systems. The introduction of such therapies has provided new opportunities for the application of intestinal endpoints in clinical trials and the understanding of underlying disease mechanisms that affect the gut in cystic fibrosis.

    Mesenteric panniculitis is an underdiagnosed inflammatory condition of unknown etiology that involves the mesenteric adipose tissue. Clinical symptoms are not specific (fever, abdominal pain, or nausea), so diagnosis is not simple. We report a case of 48-year-old man with abdominal pain and fever not responsive to antipyretics and antibiotics for 2 months, who underwent an F-FDG PET/CT after a nondiagnostic CT scan. PET/CT has proven to be a useful method for the diagnosis of mesenteric panniculitis in this patient, showing a uniformly high uptake of FDG in the mesenteric adipose tissue of the mesocolon, mesoappendix, mesosigmoid, and mesorectum.

    Adenoid cystic carcinoma is a malignant salivary gland tumor with typical histologic patterns. The majority of the se tumors occurs in the minor salivary glands, especially mucosa of the hard palate. The authors experienced the patients, who complained the tumor-like soft tissue masses on the palatal and mouth floor area. After careful analysis of clinical, radiological and histopathological findings, we diagnosed them as adenoid cystic carcinomas in the minor salivary glands, obtained results were as follows : 1. Main clinical symptoms were a slow growing soft tissue mass with normal intact mucosa on the palatal area, and soft tissue mass with mild pain on the mouth floor area. 2. In the radiographic examinations, soft tissue masses were observed with invasion to adjacent structures, and moderate defined, heterogeneous soft tissue mass with enhanced margin, respectively. 3. In the histopathologic examinations, dark-stained, small uniform ballad's cells in the hyaline or fibrous stroma were observed as solid and cribriform patterns, respectively.

    Tumors of the lacrimal gland comprise a wide spectrum, of which the most common demonstrate epithelial and lymphoid differentiation. The diagnosis of lacrimal gland tumors depends primarily on histological evaluation, as do the choice of treatment and prognosis. For some lacrimal gland neoplasms......, such as adenoid cystic carcinoma, the outlook is grave. Optimal treatment for several lacrimal gland tumors is also a matter of controversy. However, recent progress has been made in the molecular and genetic understanding of tumorigenesis for such lesions. This article presents an overview of the histopathology...... of lacrimal gland tumors, together with their epidemiological features, clinical characteristics, and treatment strategies....

    2012-07-01

    Lymphangiomas are uncommon congenital malformations of the lymphatic system, generally diagnosed during childhood. These malformations are rarely seen in adults, and the literature provides poor guidelines for treatment options that must be carefully applied to the facial region. Diagnosis in adult subjects is difficult to achieve, and also management of these conditions is still challenging because they tend to infiltrate adjacent tissues, causing frequent relapses. Radical surgery is the main form of treatment, avoiding the sacrifice of function or aesthetics of the patient. Two cases of cystic lymphangioma of the facial region found in adults are described from a clinical and pathologic point of view. The aim of this article was to point out that an early recognition of cystic lymphangioma is a crucial goal to initiate a prompt treatment avoiding serious complication.

    Cystic fibrosis is the most common life-shortening recessively inherited disorder in the Caucasian population. The genetic mutation that most frequently provokes cystic fibrosis (ΔF508) appeared at least 53,000years ago. For many centuries, the disease was thought to be related to witchcraft and the "evil eye" and it was only in 1938 that Dorothy H. Andersen characterized this disorder and suspected its genetic origin. The present article reviews the pathological discoveries and diagnostic and therapeutic advances made in the last 75 years. The review ends with some considerations for the future. Copyright © 2015 Elsevier España, S.L.U. and AEEH y AEG. All rights reserved.

    Full Text Available A 14-year-old was girl admitted to our hospital with a subcutaneous mass of the occipital head. The mass had grown for 6 years, after she had sustained a head injury at the age of 6, and was located directly under a previous wound. Skull X-ray Photograph (xp, computed tomography (CT, and magnetic resonance imaging (MRI showed a bony defect and cystic changes in the skull corresponding to a subcutaneous mass. Bone scintigraphy revealed partial accumulation. The patient underwent total removal of the skull mass, and the diagnosis from the pathological findings of the cyst wall was fibrous dysplasia (FD. The radiographic findings for cystic cranial FD can be various. Progressive skull disease has been reported to be associated with head trauma, but the relationship between cranial FD and head trauma has not been previously reported. Previous studies have suggested that c-fos gene expression is a key mechanism in injury-induced FD.

    Full Text Available Abstract Background Tracheal tumors are often misdiagnosed as asthma and are treated with inhaled steroids and bronchodilators without resolution. Case Presentation Here, a patient with tracheal adenoid cystic carcinoma who had been previously diagnosed with difficult asthma was reported. The possibility of the presence of localized airway obstruction was raised when the flow-volume curve suggesting fixed airway obstruction, was obtained. Conclusion The presenting case report emphasizes the fact that not all wheezes are asthma. It is critical to bear in mind that if a patient does not respond to appropriate anti-asthma therapy, localized obstructions should be ruled out before establishing the diagnosis of asthma.

    Adenoid cystic carcinoma of the breast constitutes approximately 0.1% of all breast tumors. They can be located in the trachea, bronchus, cervix, lacrimal gland, and skin as well as the breast. Tumors in the breast have better prognoses compared to those in other locations. The diagnosis and treatment planning of this tumor is challenging due to its rare incidence. In this article, we presented a case that was diagnosed with adenoid cystic carcinoma of the breast upon pathology evaluation. A 59-year-old female patient was admitted to our clinic due to a mass in her right breast. Her mammography revealed a 1 cm in diameter mass in the upper outer quadrant of the right breast, which was classified as BIRADS 4C (Breast Imaging Reporting and Data System). On magnetic resonance imaging (MRI) the lesion was also reported as BIRADS 4C. The patient underwent breast conserving surgery (BCS), and the pathology result was reported as adenoid cystic carcinoma of the breast. The patient received chemo-radiotherapy in the postoperative period. Adenoid cystic carcinoma of the breast has been first described in the salivary glands. They can be confused with benign lesions both on physical and radiological examinations. Sentinel lymph node biopsy (SLNB) can be used since axillary metastases are rare. Local recurrence and distant metastases are also very rare. Usually, BCS followed by radiotherapy is adequate to obtain local control. In selected patients with a poor prognosis, chemotherapy and hormonal therapy should be added to the treatment.

    We report a rare case of synchronous clear cell renal cell carcinoma and multilocular cystic renal cell neoplasia of low malignant potential in the same kidney. The tumors were seen incidentally in a 45-year-old man. Pathologic study revealed that the former tumor was nucleolar grade 2, and the multilocular cystic renal cell neoplasia of low malignant potential was nucleolar grade 1. At immunohistochemistry, the clear cells in both tumors were positive for CD10 and CA IX. Interestingly, these uncommon synchronous tumors showed a different KRAS/NRAS mutation analysis that was characterized by KRAS mutation at codon p.G12C in the clear cell renal cell carcinoma, while this mutation was not present in the case of multilocular cystic renal cell neoplasia of low malignant potential. NRAS mutation was not seen in any of the tumors.

    2012-04-01

    Full Text Available Mesenteric ischemia is relatively a rare disorder seen in the emergency department (ED. Due to the effect of hypobaric hypoxia and higher liability for thrombosis encountered in high altitude areas, acute occlusive mesenteric ischemia (AOMI would represent an actual challenge in Taif and related districts. Another risk factor is that about twenty-five percent of Saudis are victims of diabetes due to the changes in lifestyle and diet leading to increasing levels of obesity. Vague nonspecific clinical findings and limitations of diagnostic studies in addition to cultural and social factors, may lead to late presentation making the diagnosis a significant challenge and in turn higher morbidity and mortality are expected. Objectives: In this study, we review type of AOMI, pattern of presentation, laboratory, radiological, Intraoperative findings and results of treatment in 36 patients who were admitted to King Abdul Aziz Specialist Hospital and King Faisal Hospital, Al Taif, Saudi Arabia from January 2009 to January 2012. Methods: 36 patients with final diagnosis of AOMI were included in this retrospective study by means of review of their files and medical records. Results: The disease was more common in men than women (23 male and 13 females. The mean age of patients was 54 years. The mean time of presentation was 2.4 days after occurrence of symptoms. Abdominal pain was the most common symptom of patients followed by nausea, vomiting, constipation and bloody diarrhea. On physical examination; tachycardia was prevalent, Oliguria was seen in approximately 69.4% of patients, 11.1% of patients were in shock status. All patients had abdominal tenderness and 61.1% of patients had marked peritoneal signs (rebound tenderness with guarding or/and rigidity. Twenty one/36 (58.3% patients were diabetics, 17/36 patients (47.2% were hypertensive and 8/36 patients (22.2% with associated cardiac disorders. In laboratory tests, Leukocytosis was present in all

  11. Levobupivacaine induces vasodilatation, but not vasoconstriction, in rat mesenteric artery

    Directory of Open Access Journals (Sweden)

    Liciane dos Santos MENEZES

    Full Text Available Abstract Introduction Levobupivacaine (LEVO can replace analgesia because it exhibits low toxicity and causes minor vasoconstriction, enabling its use in patients in whom vasoconstrictors are contraindicated. Objective We aimed to evaluate the effects of LEVO in isolated rat superior mesenteric artery by using the vascular reactivity technique and compare its effect to that of lidocaine. Material and method Arterial rings were obtained from the mesenteric artery of male Wistar rats and kept in organ baths. For recording isometric contractions, each ring was suspended by cotton threads from a force transducer, which was connected to a data acquisition system. Result Both lidocaine and LEVO did not show a vasoconstrictor effect on the basal tone of the arterial rings with functional endothelium. However, when the rings were pre-contracted with phenylephrine, both drugs were able to induce concentration-dependent vasodilatation. The vasodilator effect induced by LEVO did not change after removal of the endothelium, or with the addition of tetraethylammonium (1 mM, a non-selective K+ channel blocker. In the rings without functional endothelium, which were pre-contracted with depolarizing Tyrode’s solution (KCl 80 mM, LEVO-induced vasodilatation was not significantly different from that observed in the rings pre-contracted with phenylephrine. Moreover, it did not show a significant additional vasodilator effect compared to the maximal vasodilator effect of nifedipine. Conclusion This study demonstrated that LEVO produces a vasodilator effect in the rat superior mesenteric artery in an endothelium-independent manner. This effect seems to be mediated via Ca2+ channel blockade in the vascular smooth muscle cells.

    Full Text Available Background: The aim of this study was to determine the level of lipid peroxidation and tissue protein after superior mesenteric artery occlusion tissue damage. The effect of melatonin as anti oxidant and free radical scavenger in prevention of tissue damage, were also evaluated. Methods: Thity six young male Wisatr-Albino rats (weight: 80-120 gr, were divided equally in 6 group with different concentrations of melatonin (10,20,30 mg/kg treatment. Group 1was control, group 2 the sham that surgical process was applied until superior mesenteric artery dissection and received vehicle solution only in equally volume by intra muscular route. Group 3 was ischemia- reperfusion (I/R, group 4 was I/R plus melatonin 10 mg/kg, group 5 I/R plus melatonin 20 mg/kg and finally group 6 I/R plus melatonin 30 mg/kg. After laparatomy, a microvascular atraumatic clip was placed across the superior mesenteric artery under general anaesthesia and itbremoved after ischemia for 30 minutes. The first dose of melatonin was applied just beforereperfusion, second dose, after reperfusion and third dose on the second day .On third day rats were killed and their bowels were removed. The level of tissue melandialdehyde (MDA as index of lipid peroxidation and tissue protein was determined. Results: The level of tissue MDA were significantly lower in group 4, 5, 6 than group 3 (p0, 05. Conclusion: These results suggest that melatonin 10 mg/kg has antioxidant effect in prevention of inducing tissue damage during SMA occlusion in rat intestine.

    Three case reports are presented with mesenteric and portal venous gas secondary to mesenteric infarction. In these patients with ileus, abdominal CT Scan appears as the most reliable diagnosis procedure. It can detect intravascular gas but also abnormalities of the intestinal wall such as intramural gas even without contrast. In mesenteric infarction, mesenteric and portal venous gas are radiological signs which considerably worsen the prognosis. (author) 7 refs.

    Polyarteritis nodosa (PAN) is a multisystem disease characterized by necrotizing vasculitis of small and medium-sized arteries, and in 50 % of all cases there is gastrointestinal involvement. We describe a patient with PAN involving the gastrointestinal tract. A small bowel series showed nodular fold thickening, submucosal filling defects, shallow ulcerations, segmental luminal narrowing, and decreased peristalsis at the duodenum, jejunum, and ileum; superior mesenteric arteriography showed hypervascularity and microaneurysm. Segmental resection of the small bowel indicated the presence of PAN. (author). 10 refs.,3 figs.

    2007-01-01

    Mesenteric lipodystrophy is a rare pathological condition affecting the mesentery. Its initial presentation is typically asymptomatic. Pathological characteristics are unspecific, and generally attributed to inflammation, unless the diagnosis is suspected. Laparoscopy done for other reasons has been, as in this case, unsuccessful in providing evidence for the correct diagnosis, thus requiring laparotomy due to lack of diagnostic tissue. After 6 mo no further medical therapy is required, as the patient remains asymptomatic. Discussion of this case and a brief review of the literature are presented in the following paragraphs.

    Full Text Available The use of shockwave lithotripsy is currently the mainstay of treatment in renal calculosis. Several complications including vessel injuries have been implied to extracorporeal shockwave lithotripsy. We report an isolated dissection of the superior mesenteric artery in a 60-year-old male presenting with abdominal pain which occurred three days after extracorporeal shockwave lithotripsy. The patient was treated conservatively and the abdominal pain subsided 24 hours later. The patient's history, the course of his disease, and the timing may suggest a correlation between the dissection and the ESWL.

    We describe a technique for rescue surgery of autologous arterovenous fistula (AVF), using bovine mesenteric vein (BMV), which may be used in patients with autologous AVF malfunction caused by steno-occlusion on the arterial side or by fibrosis of the first portion of the vein. To preserve the autologous AVF, we replaced the diseased portion of the artery, or the first centimeters of the vein, by a segment of BMV, with the aim of saving the patency and functionality of the access. We used this technique in 16 cases. All patients underwent hemodialysis treatment immediately after the procedure. Infection or aneurismal dilatation of the graft in implanted BMV was never observed.

    A middle-aged man was being investigated for constipation. Abdominal radiographs incidentally revealed a large, densely calcified, rounded mass within the pelvic cavity. A CT scan was performed followed by surgical excision with a differential diagnosis of calcified hematoma and an enlarged calcified lymph nodal mass. Histopathological investigation revealed a primary mesenteric extraskeletal osteosarcoma. To the best of our knowledge, a primary extraskeletal osteosarcoma arising from the mesentery has not been described previously in the English literature. The radiological features and differential diagnosis are discussed. (orig.)

    Pyometra and cystic endometrial hyperplasia are common in domestic canids and are suspected to develop as a consequence of elevated progesterone levels. Reports of uterine pathology in exotic canids are limited, with some speculating of association with contraception. This report describes pyometra, cystic endometrial hyperplasia, and ovariohysterectomy in three African hunting dogs (Lycaon pictus). Ovarian corpora lutea were detected in two of the dogs, suggesting endogenous progesterone production. One dog had a uterine adenocarcinoma and two had ovarian granulosa cell tumors. Clinical signs included anorexia, lethargy, vulvar discharge, polyuria, polydipsia, and abdominal distention. Diagnosis was based on clinical signs, physical examination, bloodwork, radiography, and ultrasonography, with confirmation through histopathologic evaluation of tissues. Cystic endometrial hyperplasia, pyometra, and uterine neoplasia have rarely been diagnosed in exotic canids; however, they should be considered as differential diagnoses in intact bitches that present with suspected reproductive disease.

    A supernumerary ovary is an exceedingly rare disorder, in which the structure containing ovarian tissue is located at some distance from the normally placed ovary. 16 cases of endometriosis or tumors originating in a supernumerary ovary have been published in the English literature, but no case of coexisting endometriosis and a tumor has been published. We present the case of a 40-year-old female with cystic endometrioma with coexisting fibroma originating in a supernumerary ovary in the rectovaginal pouch. The present case is the first to be reported with coexisting endometriosis and a tumor originating in a supernumerary ovary. Our experience with this case and the results of our previous studies of rectovaginal endometriosis indicated that the possibility of originating in a supernumerary ovary shall be examined in cases of cystic endometrioma in the rectovaginal pouch.

    Full Text Available Primary adenoid cystic carcinoma (PACC of the skin is a rare tumor with fewer than 70 cases studied in detail in the English literature. This type of tumor shows a prolonged course and a growth pattern usually manifested by multiple local recurrences and has a low potential for distant metastases. The most important modality for primary treatment is surgical resection followed by radiotherapy. We report a woman aged 43 years at the time of diagnosis, who presented with a slow-growing nodule in the right axilla without lymph node enlargement. A wide local excision was performed, and the histology revealed an adenoid cystic carcinoma. During the next 24 years, another four local recurrences were excised (the last one in 2015 and confirmed histologically to be adenoid cystic carcinoma. The patient was given 44 Gy of radiotherapy after the second surgery in 1996. PACC of the skin is a rare tumor with insufficient data concerning the efficacy of the surgical technique and chemotherapy and radiotherapy treatment, even more so in the case of multiple recurrences. After the last recurrence, the patient was offered an active follow-up based on the long tumor-free intervals in the past and because the site of the primary tumor allowed further surgical excisions in future recurrences.

Curcumin has been reviewed for its multiple molecular action on inhibiting tumor angiogenesis via its mechanisms of cyclooxygenase (COX-2, and vascular endothelial growth factor (VEGF inhibition. In this present study, we aimed to assess the effects of curcumin on preventing diabetes-induced vascular dysfunction in association with COX-2, nuclear factor-κB (NF-κB expression, and prostanoid production.Methods: Twelve-week-old male Wistar rats were separated into five groups: 1 diabetes with 0.9% normal saline (DM-NSS; n = 10, 2 diabetes treated with curcumin 30 mg/kg (n = 10, 3 diabetes treated with curcumin 300 mg/kg (n = 10, 4 the control with 0.9% normal saline (n = 10, and 5 the control treated with 300 mg/kg (n = 10. Daily oral feeding of curcumin was started at 6 weeks after the streptozotocin injection. Levels of 6-keto prostaglandin (PG F1α and thromboxane (TX B2 were determined from mesenteric perfusates using enzyme immunoassay kits. Protein kinase C (PKC-ßII and COX-2 with NF-κB levels were analyzed in the mesenteric arteries by immunofluorescent staining and immunohistochemistry, respectively.Results: The ratio of 6-keto-PGF1α and TXB2 was significantly decreased in DM-NSS compared with the control (P < 0.05. Double-immunofluorescent staining with specific antibodies for PKC-βII and a-smooth muscle actins showed that the diabetic mesenteric arteries contained increased

    Full Text Available The protein fraction of mesenteric lymph during acute pancreatitis and other critical illness is thought to contain toxic factors. However, we do not have a complete description of the mesenteric lymph proteome during acute pancreatitis. Objective The aim of this study was to define the proteomic changes in mesenteric lymph during acute pancreatitis. Setting Animal Laboratory, University of Auckland, New Zealand. Design Mesenteric lymph was collected from sixteen male Wistar rats randomised to Group 1 (n=8 with taurocholate induced acute pancreatitis and Group 2 (n=8 sham control. The lymph was subjected to proteomic analysis using iTRAQTM (Applied Biosystems, Foster City, CA, USA and liquid chromatography-tandem mass spectrometry. Results Two hundred and forty-five proteins including 35 hypothetical proteins were identified in mesenteric lymph. Eight of the 245 proteins had a significant increase in their relative abundance in acute pancreatitis conditioned mesenteric lymph, and 7 of these were pancreatic catabolic enzymes (pancreatic amylase 2, pancreatic lipase, carboxypeptidase A2, chymotrypsinogen B, carboxypeptidase B1, cationic trypsinogen, ribonuclease 1. Conclusions This is the first comprehensive description of the proteome of mesenteric lymph during acute pancreatitis and has demonstrated a significantly increased relative abundance of 7 secreted pancreatic catabolic enzymes in acute pancreatitis conditioned mesenteric lymph. This study provides a clear rationale for further research to investigate the efficacy of enteral protease inhibitors in the treatment of acute pancreatitis.

    2012-02-01

    Full Text Available Abstract Introduction Ischemic bowel disease comprises both mesenteric ischemia and colonic ischemia. Mesenteric ischemia can be divided into acute and chronic ischemia. These are two separate entities, each with their specific clinical presentation and diagnostic and therapeutic modalities. However, diagnosis may be difficult due to the vague symptomatology and subtle signs. Case presentation We report the case of a 68-year-old Caucasian woman who presented with abdominal discomfort, anorexia, melena and fever. A physical examination revealed left lower quadrant tenderness and an irregular pulse. Computed tomography of her abdomen as well as computed tomography enterography, enteroscopy, angiography and small bowel enteroclysis demonstrated an ischemic jejunal segment caused by occlusion of a branch of the superior mesenteric artery. The ischemic segment was resected and an end-to-end anastomosis was performed. The diagnosis of segmental small bowel ischemia was confirmed by histopathological study. Conclusion Mesenteric ischemia is a pathology well-known by surgeons, gastroenterologists and radiologists. Acute and chronic mesenteric ischemia are two separate entities with their own specific clinical presentation, radiological signs and therapeutic modalities. We present the case of a patient with symptoms and signs of chronic mesenteric ischemia despite an acute etiology. To the best of our knowledge, this is the first report presenting a case of acute mesenteric ischemia with segmental superior mesenteric artery occlusion.

    2008-01-01

    Full Text Available Abstract Introduction Teratomas of anterior mediastinum are rare tumors and are often slow growing, asymptomatic and detected incidentally on chest imaging. Results of surgical resection are very satisfactory. Case presentation A 19-years old male presented with an asymptomatic cystic neck mass. X-ray and CT scan of chest and neck showed an extrathyroidal multi-septate, predominantly cystic neck mass, that was continuous with a solid intrathoracic mass extending up to the level of right atrium and which contained areas of calcification and cystic necrosis. The mediastinal structures did not show any features of compression or infiltration. Fine needle aspiration cytology from the neck mass was suggestive of a dermoid cyst. In view of the extent and uncertain pathological nature of the tumor, it was excised via a combined cervical and trans-sternal route. Histo-pathology of the resected specimen confirmed the diagnosis of a mature cystic teratoma. The patient made an uneventful recovery, and after five years of follow-up, he has been symptom free with no clinical or radiological evidence of recurrent disease. We discuss the role of imaging and the need for surgical treatment to avoid possible catastrophic complications in patients with cervical and mediastinal masses of uncertain histological nature. Conclusion A mediastinal teratoma may rarely present as a cystic neck swelling due to its cephalad extension. This entity needs to be considered in cases where clinical and investigative work-up fail to provide a convincing clue to a primary neck pathology as cause of a cystic neck swelling.

    Full Text Available Abstract Background Visceral artery aneurysms (VAA, although uncommon, are increasingly being detected. We describe a case of spontaneous retroperitoneal hemorrhage from a ruptured IMA aneurysm associated with stenosis of the superior mesenteric artery (SMA and celiac trunk, successfully treated with surgery. Methods A 65-year-old man presented with abdominal pain and hypovolemic shock. Abdominal CT scan showed an aneurysm of the inferior mesenteric artery with retroperitoneal hematoma. In addition, an obstructive disease of the superior mesenteric artery and celiac axis was observed. Results Upon emergency laparotomy a ruptured inferior mesenteric artery aneurysm was detected. The aneurysm was excised and the artery reconstructed by end-to-end anastomosis. Conclusions This report discusses the etiology, presentation, diagnosis and case management of inferior mesenteric artery aneurysms.

  20. Abdominal Aortic Dissection with Acute Mesenteric Ischemia in a Patient with Marfan Syndrome

    Full Text Available Marfan syndrome is an autosomal dominant inherited disorder of connective tissue, with various complications manifested primarily in the cardiovascular system. It potentially leads to aortic dissection and rupture, these being the major causes of death. We report a patient who complained of acute abdominal pain, which presented as acute mesenteric ischemia combined with abdominal aortic dissection. Echocardiography showed enlargement of the aortic root and mitral valve prolapse. Abdominal computed tomography scan revealed acute mesenteric ischemia due to abdominal aortic dissection. Finally, the patient underwent surgery of aortic root replacement and had a successful outcome. Therefore, we suggest that for optimal risk assessment and monitoring of patients with Marfan syndrome, both aortic stiffness and the diameter of the superior mesenteric vein compared with that of the superior mesenteric artery are useful screening methods to detect acute mesenteric ischemia secondary to abdominal aortic dissection. Early diagnosis and early treatment can decrease the high mortality rate of patients with Marfan syndrome.

    Cysts are commonly seen on CT scans of the lungs, and diagnosis can be challenging. Clinical and radiographic features combined with a multidisciplinary approach may help differentiate among various disease entities, allowing correct diagnosis. It is important to distinguish cysts from cavities because they each have distinct etiologies and associated clinical disorders. Conditions such as emphysema, and cystic bronchiectasis may also mimic cystic disease. A simplified classification of cysts is proposed. Cysts can occur in greater profusion in the subpleural areas, when they typically represent paraseptal emphysema, bullae, or honeycombing. Cysts that are present in the lung parenchyma but away from subpleural areas may be present without any other abnormalities on high-resolution CT scans. These are further categorized into solitary or multifocal/diffuse cysts. Solitary cysts may be incidentally discovered and may be an age related phenomenon or may be a remnant of prior trauma or infection. Multifocal/diffuse cysts can occur with lymphoid interstitial pneumonia, Birt-Hogg-Dubé syndrome, tracheobronchial papillomatosis, or primary and metastatic cancers. Multifocal/diffuse cysts may be associated with nodules (lymphoid interstitial pneumonia, light-chain deposition disease, amyloidosis, and Langerhans cell histiocytosis) or with ground-glass opacities (Pneumocystis jirovecii pneumonia and desquamative interstitial pneumonia). Using the results of the high-resolution CT scans as a starting point, and incorporating the patient's clinical history, physical examination, and laboratory findings, is likely to narrow the differential diagnosis of cystic lesions considerably.

    Full Text Available Abstract Background Hydatidosis is a zoonosis caused by Echinococcus granulosus, and ingesting eggs released through the faeces from infected dogs infects humans. The location of the hydatid cysts is mostly hepatic and/or pulmonary, whereas musculoskeletal hydatidosis is very rare. Case presentation We report an unusual case of primary muscular hydatidosis in proximity of the big adductor in a young Sicilian man. The patient, 34 years old, was admitted to the Department of Infectious and Tropical Diseases for ultrasonographic detection, with successive confirmation by magnetic resonance imaging, of an ovular mass (13 × 8 cm in the big adductor of the left thigh, cyst-like, and containing several small cystic formations. Serological tests for hydatidosis gave negative results. A second drawing of blood was done 10 days after the first one and showed an increase in the antibody titer for hydatidosis. The patient was submitted to surgical excision of the lesion with perioperatory prophylaxis with albendazole. The histopathological examination of the bioptic material was not diriment in the diagnosis, therefore further tests were performed: additional serological tests for hydatidosis for the evaluation of IgE and IgG serotype (Western Blot and REAST, and molecular analysis of the excised material. These more specific serological tests gave positive results for hydatidosis, and the sequencing of the polymerase chain reaction products from the cyst evidenced E. granulosus DNA, genotype G1. Any post-surgery complications was observed during 6 following months. Conclusion Cystic hydatidosis should always be considered in the differential diagnosis of any cystic mass, regardless of its location, also in epidemiological contests less suggestive of the disease. The diagnosis should be achieved by taking into consideration the clinical aspects, the epidemiology of the disease, the imaging and immunological tests but, as demonstrated in this case, without

    Full Text Available Cystic duct carcinoma is known to have a better prognosis compared to its location in other biliary ducts. Only one case with a survival over ten years has been previously published. The authors report a case of survival over 13 years without recurrence or metastasis. Preoperative diagnosis of cystic duct tumor was carried in a 66-year-old male. Under the diagnosis of carcinoma of the cystic duct, the patient underwent en bloc resection of the gallbladder, cystic duct, hepaticocholedochus and lymph node dissection. A Roux-en-Y hepaticojejunostomy was performed. Histological examination revealed a moderately differentiated adenocarcinoma of the cystic duct. Five months later the patient underwent second look surgery for benign obstruction of the hepaticojejunal anastomosis. The patient is still doing well 13 years later without any local recurrence or metastasis. To our knowledge, this is the longest disease-free survival ever published in the literature. This case sustains that better and longer survival is possible with a real chance of potential cure if radical surgery is performed.

With a preoperative diagnosis of peritonitis Patient was taken up for emergency laparotomy. Resection of gangrenous small bowel and end to end anastomosis was done. Intra operatively thrombus in SMV was found. Coagulation profile was normal except for elevated homocystine levels. Early postoperative period was stormy. Patient was started on LMV Heparin from day - 1. Pregangrenous changes were seen in contrast CT abdomen on Day - 4. We managed conservatively with anticoagulation therapy in the postoperative period. Pregangrenous changes disappeared with conservative management. Patient was shifted to oral warfarin and discharged on 3 rd week. Follow up Doppler USG abdomen revealed a portal vein of normal size & caliber with no evidence of thrombus. On postoperative follow up for one year, patient is doing well. Hyperhomocycteinemia is an independent predisposing factor to superior mesenteric venous thrombus.

    2008-01-01

    Acute mesenteric ischemia (AMI) is a highly-lethal surgical emergency.Several pathophysiologic events (arterial obstruction,venous thrombosis and diffuse vasospasm) lead to a sudden decrease in mesenteric blood flow.Ischemia/reperfusion syndrome of the intestine is responsible for systemic abnormalities,leading to multi-organ failure and death.Early diagnosis is difficult because the clinical presentation is subtle,and the biological and radiological diagnostic tools lack sensitivity and specificity.Therapeutic options vary from conservative resuscitation,medical treatment,endovascular techniques and surgical resection and revascularization.A high index of suspicion is required for diagnosis,and prompt treatment is the only hope of reducing the mortality rate.Studies are in progress to provide more accurate diagnostic tools for early diagnosis.AMI can complicate the post-operative course of patients following cardio-pulmonary bypass (CPB).Several factors contribute to the systemic hypo-perfusion state,which is the most frequent pathophysiologic event.In this particular setting,the clinical presentation of AMI can be misleading,while the laboratory and radiological diagnostic tests often produce inconclusive results.The management strategies are controversial,but early treatment is critical for saving lives.Based on the experience of our team,we consider prompt exploratory laparotomy,irrespective of the results of the diagnostic tests,is the only way to provide objective assessment and adequate treatment,leading to dramatic reduction in the mortality rate.

    Full Text Available We herein report a case of phlegmonous gastritis secondary to superior mesenteric artery syndrome. An 80-year-old woman visited the hospital emergency department with the chief complaints of epigastric pain and vomiting. She was hospitalized urgently following the diagnosis of superior mesenteric artery syndrome based on abdominal computed tomography findings. Conservative therapy was not effective, and phlegmonous gastritis was diagnosed based on the findings of upper gastrointestinal endoscopy and biopsy performed on the 12th day of the disease. Undernutrition and reduced physical activity were observed on hospital admission, and proactive nutritional therapy with enteral nutrition was started. An upper gastrointestinal series, performed approximately 1 month later, confirmed the persistence of strictures and impaired gastric emptying. Because conservative therapy was unlikely to improve oral food intake, open total gastrectomy was performed on the 94th day of the disease. Examination of surgically resected specimens revealed marked inflammation and fibrosis, especially in the body of the stomach. Following a good postoperative recovery, the patient was able to commence oral intake and left our hospital on foot approximately 1 month after surgery.

    Cystic fibrosis is frequently complicated by endocrine disorders. Diabetes can be expected to affect most with CF and pancreatic insufficiency and varies widely in age of onset, but early identification and treatment improve morbidity and mortality. Short stature can be exacerbated by relative delay of puberty and by use of inhaled corticosteroids. Bone disease in CF causes fragility fractures and should be assessed by monitoring bone mineral density and optimizing vitamin D status. Detecting and managing endocrine complications in CF can reduce morbidity and mortality in CF. These complications can be expected to become more common as the CF population ages.

    2016-06-01

    Cystic lesions are commonly seen in the mediastinum, and they may arise from virtually any organ. The vast majority of these lesions are benign and result in no symptoms. When large, cysts may produce symptoms related to compression of adjacent structures. The most common mediastinal cysts are pericardial and foregut duplication cysts. Both computed tomography and magnetic resonance are routinely used to evaluate these lesions. Although computed tomography offers superior spatial resolution, magnetic resonance is useful in differentiating cysts that contain proteinaceous material from solid lesions. Occasionally, cysts arise from solid lesions, such as thymoma or teratoma. Although cysts are alike in appearance, location helps narrowing the differential diagnoses.

    Pancreatic cystic lesions are being recognized increasingly due to the development of computed tomography and magnetic resonance imaging.Differential diagnosis between pseudocysts and cystic tumors is the key point for pancreatic cystic lesions.Patients with pancreatic pseudocysts generally have a history of acute or chronic pancreatitis,whereas patients with cystic tumors did not have such a history.Some pancreatic cystic lesions did not have typical imaging presentations,and they were difficult to be diagnosed.Pancreatic cystic lesions could be divided into unilocular cysts,microcystic lesions,macrocystic lesions and cysts with a solid component according to the presentations under computed tomography and magnetic resonance imaging.This typing system is helpful for the diagnosis and differential diagnosis of pancreatic cystic tumors,as well as for the guidance of therapy.%随着CT和MRI检查新技术的发展,胰腺囊性病变逐渐被临床医师认识和了解.胰腺囊性肿瘤和假性囊肿的鉴别是诊断的重点.胰腺假性囊肿患者一般具有急慢性胰腺炎病史,而胰腺囊性肿瘤没有胰腺炎病史.部分胰腺囊性肿瘤缺乏影像学特征性,在临床上常常难以鉴别.胰腺囊性病变按照CT和MRI检查的特点分为单囊性病变、微囊性病变、大囊性病变和囊实性病变.这一分型系统有助于诊断和鉴别诊断,并可以指导治疗方案和判断预后,具有重要的临床价值.

    Full Text Available Introduction. The purpose of this study is to determine the anatomic course of the first jejunal branch of the superior mesenteric vein (SMV in relation to the superior mesenteric artery (SMA. Methods. Three hundred consecutive contrast-enhanced computed tomography (CT scans were reviewed by a surgical oncologist with confirmation of findings by a radiologist. Results. The overall incidence of a first jejunal branch coursing anterior to the SMA was 41%. There was no correlation between patient gender and position of the jejunal branch. In addition, there was no correlation between size of the first jejunal branch and its location in relation to the SMA. The IMV drained into the SMV in 27% of the patients. The IMV drained into the SMV-portal vein confluence in 17% of patients and inserted into the splenic vein in 54%. An anterior coursing first jejunal branch statistically correlated with an IMV that drained into the SMV-portal vein confluence (=0.009. Conclusion. The first jejunal branch of the SMV has a highly variable course in relation to the SMA and has a higher incidence of an anterior location in this population than previously reported.

    Full Text Available Most published studies about Cystic Fibrosis (CF are European or North American. There are still few publications about the characteristics of fibrocystic populations in developing countries. The incidence of cystic fibrosis (CF in Brazil varies among different regions (1 : 10,000 in Minas Gerais, 1 : 9,500 in Paraná, 1 : 8,700 in Santa Catarina, and 1 : 1600 in Rio Grande do Sul. The prevalence of the DF508 mutation also varies according to population: 33% in Sao Paulo, 49% in Rio Grande do Sul, 27% in Santa Catarina, and 52% in Minas Gerais. Cough and nasal obstruction are the most common symptoms. The variation in nasal polyposis prevalence may be explained by population genotypic characteristics in a country that spans a continent. Findings on nasal endoscopy and computed tomography (CT have better correlation than do this information compared with surgical and clinical history. Microbiologic studies suggest a high level of early contamination of the airways. Sensorineural hearing loss (SNHL occurs in these patients as a result of ototoxic antibiotics. The data compiled in this paper is useful, but also lead to the general agreement that more research would be welcome due to the unique characteristics of this country.

    Mutations in cystic fibrosis transmembrane conductance regulator gene, CFTR, are responsible for cystic fibrosis, CF, a channelopathie. CFTR protein is a multifunctional protein with a main function of Cl(-) channel. CFTR is expressed in epithelia (upper airways, intestine, pancreas etc.). In the first part of this revue, we describe the main properties of CFTR underlying that it is not only a Cl(-) channel protein but also a multifunctional protein. We present a hypothesis which postulates that CFTR is a hub protein interacting with more than 140 proteins, and through these interactions regulates a number of functions which are abnormal in CF (ion transport, inflammation etc.). In the second part of the revue we briefly present a selection of other epithelial channelopathies due to mutations in genes of other Cl(-) or cation channels. Of note, these channels either interacts with CFTR or are considered as alternative channels in CF, and, as such, are targets for pharmacotherapies. We want to leave the reader with a message that to investigate channalopathies, to dissect the molecular mechanisms underlying channels'activity, allow not only to better understand basic mechanisms of channel regulation but in fine, to propose new targets for pharmacotherapies.

    Objective. To study the sonographic features and patterns of cystic renal carcinomas. Methods. Thirteen cases of cystic renal carcinoma confirmed by operation and pathology were examined by ultrasonography, and the cystic walls, septa and solid mural nodules were studied. Results. Solid mural nodules of some cases and irregular thickening of the cystic walls and septa were characteristic findings for the ultrasonic diagnosis of cystic renal carcinomas. According to their pathologic mechanisms and sonographic features, cystic renal carcinomas were classified into 3 patterns: unilocular cystic mass, multiloculated cystic mass and cystic-solid mass. Conclusions. Typical cystic renal carcinomas can be well diagnosed, while atypical cases may be misdiagnosed as benign renal cysts by ultrasonography. Color Doppler ultrasonography and needle aspiration guided by ultrasonography are helpful in the diagnosis of these atypical cases.

    In childhood mature cystic teratomas are the most common type of ovarian germ cell tumors. Tumors of neuroepithelial origin are extremely rare in mature teratomas. To the authors' knowledge, this is the first case report oligodendroglioma arising in a mature cystic ovarian teratoma in children. A 13-year-old girl presented with a history of pelvic pain for 2 months. An ultrasound examination showed a monolateral multicystic, calcific ovarian mass, measuring approximately 6 x 5 cm, arising in the left over and adnexia, suggesting a teratoma. An exploratorative laparotomy and ooferectomy were performed. On histopatological examination, various samples from cystic areas had mature tissues from all 3 germ cell layers, including skin, bone, bronchial structures, and cerebellum. Sections from solid areas showed uniform population of monotonous, rounded cells with indistinct cytoplasm and having perinuclear halo (fried-egg appearance) on a fibrillary, neuropilic background. Microcalcifications as calcospherites were noted in the stroma. Based on the typical morphological features, the cased was diagnosed as mature cystic teratoma with low-grade oligodendroglioma. To the authors' knowledge, there are a few reports in the literature of an oligodendroglioma arising in an ovarian teratoma in adults and this presented patient is the first case in childhood.

    Desmoplastic fibroma (DF) is a rare, locally aggressive, solitary tumor microscopically composed of well-differentiated myofibroblasts with abundant dense collagen deposition. The most common sites are the long tubular bones and mandible. To our knowledge, only five cases of DF in the ribs have been reported. Here, we report a case of DF in this rare location with unusual radiological findings. A 40-year-old man presented with a 4-year history of swelling of the right chest wall. Radiographs revealed a mass at the right 9th rib, and computed tomography demonstrated a mass of 14 x 12 x 8 cm at the right 9th rib with expanded cystic change and marked calcification that appeared to have arisen from the bone. Open biopsy suggested DF. Total excision was performed, and the chest wall was reconstructed. The surgical specimen was a yellowish tumor with multilocular cystic change containing a viscous liquid. The tumor was composed of a proliferation of less-atypical spindle-shaped cells in a collagenous background. The cystic change was observed in the extra-osseous lesion. No β-catenin cytoplasmic/nuclear accumulation was detected, and no β-catenin or GNAS genetic mutations were detected. A final diagnosis of DF was made on the basis of the pathological and radiological findings. The patient was successfully treated with total excision of the tumor with no evidence of recurrence 6 months after surgery. (orig.)

    UNLABELLED: This study investigated the effect of the metabolic syndrome associated risk factors hyperglycemia (glucose [Glc]), hyperinsulinemia (insulin [Ins]) and low-grade inflammation (tumor necrosis factor α [TNFα]) on the vasomotor responses of resistance arteries. Isolated small mesenteric...... arteries from 3-month-old Sprague-Dawley rats, were suspended for 21-23 h in tissue cultures containing either elevated Glc (30 mmol/l), Ins (100 nmol/l), TNFα (100 ng/ml) or combinations thereof. After incubation, the vascular response to noradrenaline (NA), phenylephrine, isoprenaline and NA...... in the presence of propranolol (10 µmol/l) was measured by wire myography. RESULTS: Arteries exposed only to combinations of the risk factors showed a significant 1.6-fold increase in the contractile NA sensitivity, which suggests that complex combinations of metabolic risk factors might lead to changes...

    Full Text Available Mesenteric panniculitis (also known as sclerosing mesenteritis is a chronic inflammatory disease of the mesenteric connective tissue. It is known to have a wide spectrum of clinical and radiological presentations. In general, biopsy is recommended for diagnosis; however, a recent study proposed that a negative positron emission tomography- computerized tomography (PET-CT scan is accurate in differentiating benign and neoplastic mesenteric processes [Br J Radiol 2006;79:37–43]. The following case report questions the accuracy of PET-CT in this setting and confirms the requirement for biopsy to rule out the presence of mesenteric lymphoma.

    Full Text Available Extraovarian granulosa cell tumor (GCT is a very uncommon tumor, assumed to arise from the ectopic gonadal tissue along the embryonal route of the genital ridge. One such rare case of extraovarian GCT was encountered in a 58-year-old female who presented with a large intraabdominal lump. Computerized tomography revealed one large retroperitoneal mass measuring 15cm x 16cm and another mesenteric mass of 8cm x 5cm size. The patient had a history of hysterectomy with bilateral salpingooophorectomy 20 years ago for uterine leiomyoma. Ultrasonography-guided aspiration smears revealed cytological features suggestive of GCT. Histopathological examination of the excised masses showed features of adult-type GCT. Because metastatic epithelial tumors, particularly from the ovaries, may show identical morphology, immunostains for inhibin and epithelial membrane antigen (EMA were performed. The tumor showed positivity for inhibin while EMA was negative thus confirming the diagnosis of GCT. As this patient had no previous history of GCT and was oophorectomized 20 years ago, the tumor was considered as extraovarian. A diagnosis of extraovarian GCT should be carried out after excluding any previous history of GCT of the ovary. Immunostains help to differentiate GCTs from other neoplasms.

    Perinatal detection of neonatal suprarenal masses has increased. Here, we report an unusual case of an adrenal cystic neuroblastoma that presented as a purely cystic lesion upon initial postnatal ultrasonography (US) and showed rapid evolution to a mixed cystic and solid mass during follow-up US and MRI. We suggest a short-term (two weeks) follow-up US for neonatal adrenal cystic lesions, even if they appear as purely cystic.

    Full Text Available Abstract Background There are some early clinical indicators of cardiac ischemia, most notably a change in a person's electrocardiogram. Less well understood, but potentially just as dangerous, is ischemia that develops in the gastrointestinal system. Such ischemia is difficult to diagnose without angiography (an invasive and time-consuming procedure mainly due to the highly unspecific nature of the disease. Understanding how perfusion is affected during ischemic conditions can be a useful clinical tool which can help clinicians during the diagnosis process. As a first step towards this final goal, a computational model of the gastrointestinal system has been developed and used to simulate realistic blood flow during normal conditions. Methods An anatomically and biophysically based model of the major mesenteric arteries has been developed to be used to simulate normal blood flows. The computational mesh used for the simulations has been generated using data from the Visible Human project. The 3D Navier-Stokes equations that govern flow within this mesh have been simplified to an efficient 1D scheme. This scheme, together with a constitutive pressure-radius relationship, has been solved numerically for pressure, vessel radius and velocity for the entire mesenteric arterial network. Results The computational model developed shows close agreement with physiologically realistic geometries other researchers have recorded in vivo. Using this model as a framework, results were analyzed for the four distinct phases of the cardiac cycle – diastole, isovolumic contraction, ejection and isovolumic relaxation. Profiles showing the temporally varying pressure and velocity for a periodic input varying between 10.2 kPa (77 mmHg and 14.6 kPa (110 mmHg at the abdominal aorta are presented. An analytical solution has been developed to model blood flow in tapering vessels and when compared with the numerical solution, showed excellent agreement. Conclusion An

    Full Text Available Uncontrolled arterial bleeding during laparoscopic cholecystectomy is a serious problem and may increase the risk of bile duct damage. Therefore, accurate identification of the anatomy of the cystic artery is very important. Cystic artery is notoriously known to have a highly variable branching pattern. We reviewed the anatomy of the cystic artery and its branch to cystic duct as seen through the video laparoscope. A single artery to cystic duct with the classical “H-configuration” was demonstrated in 161 (91.47% patients. This branch may cause troublesome bleeding during laparoscopic dissection in the hepatobiliary triangle. Careful identification of artery to cystic duct is helpful in the proper dissection of Calot’s triangle as it reduces the chances of hemorrhage and thus may also be helpful in prevention of extrahepatic biliary radical injuries.

    To evaluate the sonographic features of mesenteric lymphadenopathy in childhood epidemic aseptic meningitis and to assess their clinical significance. Thirty-three patients (25 male, 8 female: mean age, 8.6 years) with a diagnosis of aseptic meningitis were prospectively evaluated with abdominal ultrasonography for the presence of enlarged mesenteric nodes. The size and number of enlarged mesenteric lymph nodes were analyzed in relationship with the patient's age, between the patients with abdominal pain or diarrhea (16 cases, 48%) and asymptomatic patients (17 cases, 52%). Mesenteric lymphadenopathy was seen in 31 patients (94%), all 16 symptomatic and 15 of the 17 asymptomatic patients. The number of enlarged nodes was most prevalent between 6-10, seen in 16 patients (52%) and the largest node ranged in size from 4 to 8 mm. Among the 31 patients with mesenteric lymphadenopathy, the mean size of the largest node was statistically different between the symptomatic (6.0 mm) and asymptomatic (5.0 mm) groups (p = 0.021). The number of enlarged nodes and the patient's age were not statistically different between the two groups. Mesenteric lymphadenopathy was seen in almost all cases of childhood epidemic aseptic meningitis, and may be related to the mesenteric lymphadenitis caused by enterovirus

    Pheochromocytomas are usually solid tumours. But it can present as cystic lesions in the adrenal gland. Cystic lesions in adrenal gland with hypertension needs attention to rule out pheochromocytoma. If ignored, it may lead to hypertensive emergency, multisystem crisis and death. Early diagnosis with biochemistry, Computed Tomography (CT) or Magnetic Resonance Imaging (MRI) of abdomen, proper functional imaging like Meta Iodo Benzyl Guanidine (MIBG) scan is essential. Proper preoperative preparation is important to prevent hypertensive crisis during and after surgery. We are reporting a case of cystic pheochromocytoma in a young male. PMID:28050427

    Cystic fibrosis is a complex multi-systemic chronic disease characterized by progressive organ dysfunction with development of fibrosis, possibly affecting the heart. Over the last four decades pathological, experimental, and clinical evidence points towards the existence of a specific myocardial involvement in cystic fibrosis. Multi-modality cardiac imaging, especially recent echocardiographic techniques, evidenced diastolic and/or systolic ventricular dysfunction in cystic fibrosis leading to the concept of a cystic fibrosis-related cardiomyopathy. Hypoxemia and inflammation are among the most important factors for heart involvement in cystic fibrosis. Cystic Fibrosis Transmembrane Regulator was found to be involved in the regulation of cardiomyocyte contraction and may also account for cystic fibrosis-related myocardial dysfunction. This review, mainly focused on echocardiographic studies, seeks to synthesize the existing literature for and against the existence of heart involvement in cystic fibrosis, its mechanisms and prognostic implications. Careful investigation of the heart function may be helpful for risk stratification and therapeutic decisions in patients with cystic fibrosis.

    The aim of this study is to establish the biomechanics, presentation and diagnosis of mesenteric avulsions following blunt abdominal trauma and reach a consensus on their overall management. A systematic review of literature in MedLine, Embase, Scopus and CINHAL in English language from 1951 to November 2014 was performed. A total of 20 reported cases were identified. Variables including patient's demographics, signs and symptoms, mechanism of injury, investigative modality, management, length of stay, follow-up and outcomes were reviewed and analyzed. The median age of the cohort was 28.5 years (range 10-58 years), with a male-to-female ratio of 3:1. The commonest mechanism of injury was road traffic accident due to seat belt restraint (n = 12, 60 %). The commonest presentation was diffuse abdominal tenderness (n = 10, 45 %) followed by ecchymosis/bruising (n = 9, 40 %). Computed tomography (CT) remained the investigative modality of choice (n = 9, 45 %). All cases had an emergency exploratory laparotomy (n = 18, 90 %) within the initial 24 h and the median length of stay was 19 days (range 4-90 days). The overall mortality was 15 % (n = 3). Mesenteric avulsion is rare and has a complex and vague presentation. Due to its potential mortality and morbidity, emergency physicians should keep a high index of suspicion in individuals with blunt abdominal trauma from any mechanism of injury.

    Acromegaly is a disease associated with an increased risk for several kinds of neoplasms including colon and thyroid cancer. Although the association between acromegaly and pancreatic neoplasms has not been elucidated, it has recently been reported that GNAS gene mutations were found in 58% of intraductal papillary mucinous neoplasms (IPMNs), which are representative pancreatic cystic lesions, suggesting a link between IPMNs and acromegaly. To assess the prevalence of pancreatic cystic lesions in patients with acromegaly, we performed a retrospective cross-sectional single institute study. Thirty consecutive acromegalic patients (20 females and 10 males; mean age, 60.9 ± 11.9 years) who underwent abdominal contrast-enhanced computed tomography or magnetic resonance imaging between 2007 and 2015 at Kobe University Hospital were recruited. We also analyzed the relationship between presence of pancreatic cystic lesions and somatic GNAS mutations in pituitary tumors. Seventeen of 30 (56.7%) patients studied had pancreatic cystic lesions. Nine of 17 patients (52.9%) were diagnosed with IPMNs based on imaging findings. These results suggest that the prevalence of IPMNs may be higher in acromegalic patients in acromegalic patients than historically observed in control patients (up to 13.5%). In patients with pancreatic cystic lesions, the mean patient age was higher and the duration of disease was longer than in those without pancreatic cystic lesions (67.0 ± 2.3 vs. 53.0 ± 2.7 years, p lesions. These data demonstrate that old or long-suffering patients with acromegaly have a higher prevalence of pancreatic cystic lesions. Moreover, the prevalence of pancreatic cystic lesions may be increased in acromegalic patients.

    The cysts may potentially affect any organ; adrenals cysts are rare. This is a review of the literature regarding adrenal cysts, focusing on children and young adults. Three major types have been described: pure cysts (endothelial, epithelial, and hemorrhagic or pseudocyst), parasitic (as hydatid) cysts and cystic part of a tumour (most frequent are neuroblastoma, ganglioneuroma, pheocromocytoma, and teratoma). The complications are: bleeding, local pressure effects; infection; rupture (including post-traumatic); arterial hypertension due to renal vessels compression. Adrenal hemorrhage represents a particular condition associating precipitating factors such as: coagulation defects as Factor IX or X deficiency, von Willebrand disease, thrombocytopenia; antiphospholipid syndrome; previous therapy with clopidogrel or corticosteroids; the rupture of a prior tumour. At birth, the most suggestive features are abdominal palpable mass, anemia, and persistent jaundice. Adrenal insufficiency may be found especially in premature delivery. The hemorrhage is mostly self-limiting. Antenatal ultrasound diagnosis of a cyst does not always predict the exact pathology result. The most important differential diagnosis of adrenal hemorrhage/hemorrhagic cyst is cystic neuroblastoma which is highly suggestive in the presence of distant metastases and abnormal catecholamine profile. The major clue to differentiate the two conditions is the fact that the tumor is stable or increases over time while the adrenal hemorrhage is expected to remit within one to two weeks. Pediatric adrenal cysts vary from simple cysts with a benign behavior to neoplasia- related lesions displaying severe prognosis as seen in cystic neuroblastoma. A multidisciplinary team is required for their management which is conservative as close follow-up or it makes necessary different surgical procedures in cases with large masses or if a malignancy suspicion is presented.

  17. Gastrointestinal manifestations in cystic fibrosis.

    Science.gov (United States)

    Eggermont, E

    1996-08-01

    CFTR, or cystic fibrosis transmembrane conductance regulator, the gene product that is defective in cystic fibrosis, is present in the apical membrane of the epithelial cells from the stomach to the colon. In the foregut, the clinical manifestations are not directly related to the primary defect of the CFTR chloride channel. The most troublesome complaints and symptoms originate from the oesophagus as peptic oesophagitis or oesophageal varices. In the small intestinal wall, the clinical expression of CF depends largely on the decreased secretion of fluid and chloride ions, the increased permeability of the paracellular space between adjacent enterocytes and the sticky mucous cover over the enterocytes. As a rule, the brush border enzyme activities are normal and there is some enhanced active transport as shown for glucose and alanine. The results of continuous enteral feeding of CF patients clearly show that the small intestinal mucosa, in the daily situation, is not functioning at maximal capacity. Although CFTR expression in the colon is lower, the large intestine may be the site of several serious complications such as rectal prolapse, meconium ileus equivalent, intussusception, volvulus and silent appendicitis. In recent years colonic strictures, after the use of high-dose pancreatic enzymes, are being increasingly reported; the condition has recently been called CF fibrosing colonopathy. The CF gastrointestinal content itself differs mainly from the normal condition by the lower acidity in the foregut and the accretion of mucins and proteins, eventually resulting in intestinal obstruction, in the ileum and colon. Better understanding of the CF gastrointestinal phenotype may contribute to improvement of the overall wellbeing of these patients.

    Cystic pancreatic lesions are often discovered incidentally as an asymptomatic finding, at a rate which is increasing considerably. In recent years the understanding of such tumors has become clearly differentiated. The spectrum of relevant lesions includes in particular the intraductal papillary mucinous neoplasm (IPMN), serous cystic neoplasm (SCN) and mucinous cystic neoplasm (MCN). With certain knowledge of their histological and radiomorphological structure as well as their distribution in terms of location, age and sex, such tumors are easy to differentiate and demarcate from common pancreatic pseudocysts. This also implies the fundamental understanding of complementary endoscopic procedures such as endosonography, which enables aspiration of the content of the cyst. A number of cystic pancreatic lesions have the potential to undergo malignant transformation along the adenoma-carcinoma sequence and therefore necessitate a differentiated approach to their radiological management. This review aims to develop a broad understanding of the pathological and radiomorphological characteristics of cystic pancreatic lesions and provides advice regarding procedures, particularly with respect to incidentally detected lesions.

    Pancreatic cystic neoplasm is mainly divided into three types, serous cystic neoplasm ( SCN ) , mucinous cystic neoplasm (MCN) and intraductal papillary mucinous tumor (IPMN). SCN is mostly benign, rarely malignant, and mostly microcystadenoma. Classic appearance of SCN is honeycomb-like structure. MCN has obvious malignant tendency, mostly larger and separated cyst. The characteristic of IPMN is connection with the pancreatic duct which is usually dilatation. Imaging features of the cyst is the main evidence to identify the type of the cystic tumor. It should also be differentiated from solid pseudopapillary tumor (SPT) and pseudocyst. All the cystic tumors of pancreas, including those already got a clear diagnosis and small lesion without obvious symptoms or smaller IPMN of branch-type, should be treated with surgery. The majority can get long-term survival with complete tumor resection. Specific surgical approach should be based on tumor location, histological type, the relationship with the main pancreatic duct, the surgeon experience and the systemic situation of the patients.%胰腺囊性肿瘤主要分为3类:浆液性囊性肿瘤(serous cystic neoplasm,SCN)、黏液性囊性肿瘤(mucinous cystic neoplasm,MCN)和导管内乳头状黏液性囊腺瘤(intraductal papillary mucinous neoplasm,IPMN).SCN多为良性,恶性罕见,多是微囊腺瘤,典型表现呈蜂巢样结构.MCN有明显的恶性倾向,诊断多为体积较大且有分隔的囊肿.IPMN的特点是囊肿与胰管相通,伴有胰管扩张.囊肿的影像学特征是囊性肿瘤鉴别的主要依据,还应注意与实性假乳头状瘤(solid pseudopapillary tumors,SPT)和假性囊肿相鉴别.除了已经获得的明确诊断、肿瘤较小且无明显症状的SCN或较小的分支型IPMN之外,胰腺囊性肿瘤都应积极手术治疗.肿瘤完整切除的患者多数可以获得长期存活以上肿瘤的.具体手术方式应根据肿瘤所在部位、病理类型、与主胰管的关系、

    Full Text Available Introduction. Cystic fibrosis or mucoviscidosis is a genetically caused disease. The intensity of disease and histopathological changes grow throughout the life. According to the literature, pathological changes characteristic of cystic fibrosis become noticeable around the sixth month of life. Case Report. After amniocentesis of a 5-lunar month-old fetus had been done, which confirmed cystic fibrosis, the Ethics Commission approved the preterm labor. The autopsy and histopathological analysis demonstrated the existence of typical histopathological changes in the pancreas and intestines. Discussion. In the late fetal period or during the period around the delivery, cystic fibrosis is usually manifested as meconial cap with or without obstruction of the intestinal lumen. Morphological changes in the exocrine glands usually develop only after birth. In this case, the existence of meconial obstruction, as well as the typical acidofil content in the secretory ducts and acini of the pancreas was confirmed, which is unusual for the fetal age of five months.

    Full Text Available Abstract Introduction Superior mesenteric artery syndrome is a rare cause of upper intestinal obstruction resulting from compression of the duodenum by the superior mesenteric artery and abdominal aorta. Case presentation We describe a case of superior mesenteric artery syndrome in a 61-year-old Japanese man with non-small cell lung cancer who had been treated with cisplatin-containing chemotherapy and had lost 7 kg in weight. The diagnosis was confirmed by the typical findings of abdominal computed tomography showing distended stomach resulting from compression of the third portion of the duodenum and reduction of an aortomesenteric distance and aortomesenteric angle. Conclusions This case highlights the importance of considering the possibility of superior mesenteric artery syndrome in patients treated with chemotherapy, especially those presenting with a low body mass index and showing weight loss during chemotherapy.

    Full Text Available Mesenteric panniculitis is a rare inflammatory and fibrotic process that affects the small intestine mesentery. It may occur following abdominal surgery or in association with a variety of conditions, including malignancy, infection, and certain autoimmune and inflammatory conditions. Herein, an unusual case of mesenteric panniculitis in a patient with primary Sjögren’s syndrome will be presented. The patient presented with abdominal pain, weight loss, sicca symptoms, fatigue, and arthralgia. An abdominal CT revealed mesenteric fat stranding and prominent lymph nodes of the small intestine mesentery. She was found on laboratory workup to have positive antinuclear and anti-SSa antibodies. Minor salivary gland lip biopsy revealed focal lymphocytic sialadenitis. The patient’s symptoms and CT findings improved with corticosteroids. This case suggests that Sjögren’s syndrome should be considered as an underlying disease process in the evaluation of patients with mesenteric panniculitis.

    Treatment of symptomatic, chronic mesenteric ischemia is indicated to relieve symptoms and prevent acute ischemia and death. Current therapeutic options include endovascular and open surgery. The purpose of this prospective study was to evaluate the results of bypasses to the superior mesenteric artery arising from the infrarenal aorta or infrarenal aortic grafts. From January 1999 to December 2016, 24 consecutive patients with a mean age of 61 years underwent a prosthetic bypass to the superior mesenteric artery. Nine patients (37%) presented with an associated clinically important stenosis of the celiac artery and 10 (42%) of the inferior mesenteric artery. Five patients (21%) received preoperative parenteral nutrition. Four patients (17%) underwent dual antiplatelet treatment. The donor site was the infrarenal aorta in 19 patients (79%) and an infrarenal, Dacron graft was used in 5 (21%). The origin of the bypass was from the distal infrarenal aorta or Dacron graft in 19 patients (79%) and from the proximal infrarenal aorta in 5 patients (21%). The graft material consisted of 7 mm polytetrafluoroethylene in 19 cases (79%) and 7 mm Dacron in 5 cases (21%). A concomitant bypass to the inferior mesenteric artery was performed in 4 patients (17%). The primary end points were postoperative mortality, morbidity, graft infection, late survival, primary patency, and symptom-free rate. The secondary end point was postoperative hemorrhagic complications. No postoperative mortality occurred. Postoperative morbidity included a prolonged postoperative ileus in 4 patients (17%), transitory postoperative increases in serum creatinine concentrations in 3 patients (12%), and myocardial ischemia in 2 patients (8%). No postoperative hemorrhagic complications or graft infection were observed. Overall, the cumulative survival rate was 77% at 60 months. The overall late-patency rate and freedom from recurrence of symptoms were both 87% at 60 months. Infrarenal aorta and

    Mesenteric ischaemia results from decreased blood flow to the bowel, causing cellular injury from lack of oxygen and nutrients. Acute mesenteric ischaemia (AMI) is an uncommon disorder with high morbidity and mortality, but outcomes are improved with prompt recognition and aggressive treatment. Five subgroups of AMI have been identified, with superior mesenteric artery embolism (SMAE) the most common. Older age and cardiovascular disease are common risk factors for AMI, excepting acute mesenteric venous thrombosis (AMVT), which affects younger patients with hypercoaguable states. AMI is characterized by sudden onset of abdominal pain; a benign abdominal exam may be observed prior to bowel infarction. Conventional angiography and more recently, computed tomography angiography, are the cornerstones of diagnosis. Correction of predisposing conditions, volume resuscitation and antibiotic treatment are standard treatments for AMI, and surgery is mandated in the setting of peritoneal signs. Intra-arterial vasodilators are used routinely in the treatment of non-occlusive mesenteric ischaemia (NOMI) and also are advocated in the treatment of occlusive AMI to decrease associated vasospasm. Thrombolytics have been used on a limited basis to treat occlusive AMI. A variety of agents have been studied in animal models to treat reperfusion injury, which sometimes can be more harmful than ischaemic injury. Chronic mesenteric ischaemia (CMI) usually is caused by severe obstructive atherosclerotic disease of two or more splanchnic vessels, presents with post-prandial pain and weight loss, and is treated by either surgical revascularization or percutaneous angioplasty and stenting.

    Full Text Available Mesenteric fat belongs to visceral fat. An increased deposition of mesenteric fat contributes to obesity associated complications such as type 2 diabetes and cardiovascular diseases. We have investigated the therapeutic effects of bardoxolone methyl (BARD on mesenteric adipose tissue of mice fed a high-fat diet (HFD. Male C57BL/6J mice were administered oral BARD during HFD feeding (HFD/BARD, only fed a high-fat diet (HFD, or fed low-fat diet (LFD for 21 weeks. Histology and immunohistochemistry were used to analyse mesenteric morphology and macrophages, while Western blot was used to assess the expression of inflammatory, oxidative stress, and energy expenditure proteins. Supplementation of drinking water with BARD prevented mesenteric fat deposition, as determined by a reduction in large adipocytes. BARD prevented inflammation as there were fewer inflammatory macrophages and reduced proinflammatory cytokines (interleukin-1 beta and tumour necrosis factor alpha. BARD reduced the activation of extracellular signal-regulated kinase (ERK and Akt, suggesting an antioxidative stress effect. BARD upregulates energy expenditure proteins, judged by the increased activity of tyrosine hydroxylase (TH and AMP-activated protein kinase (AMPK and increased peroxisome proliferator-activated receptor gamma coactivator 1-alpha (PGC-1α, and uncoupling protein 2 (UCP2 proteins. Overall, BARD induces preventive effect in HFD mice through regulation of mesenteric adipose tissue.

    2013-01-01

    Introduction: Heterotopic mesenteric ossification is an extremely rare condition, which often follows trauma and is frequently symptomatic. To date, there are no reports in the literature of abdominal compartment syndrome occurring after surgical resection of mesenteric calcification. The present report documents an unusual case of compartment syndrome complicating resection of extensive mesenteric calcification despite abdominal closure with the components-separation technique. Method: A 48-year-old man undergoing components-separation technique for posttraumatic laparostomy hernia repair (ileostomy reversal and sigmoid stricture correction) was found to have extensive heterotopic mesenteric calcification, which needed resection. Results: Resection of the mesenteric calcification was complicated by intraoperative hemorrhage and unplanned small bowel resection. Later the patient developed secondary hemorrhage leading to an abdominal compartment syndrome, which was successfully treated by decompression, hemostasis, and Permacol-assisted laparotomy wound closure. The patient remains symptom-free more than 2 years after surgery. Discussion: The case herein reported gives an account of the rare occurrence of abdominal compartment syndrome following resection of posttraumatic ectopic mesenteric ossifications. It is highly unusual in that it occurred because of “secondary hemorrhage” and despite abdominal closure with the components-separation technique, which had been undertaken precisely to prevent compartment syndrome with direct closure. It therefore highlights the need for continued clinical vigilance in complex posttraumatic cases. PMID:23573333

    Objective: The counterclockwise rotation of the SMV on SMA is a normal and non-specific finding, which results in an incomplete swirl formation on CT scans. However, it has a potential to be misinterpreted as ‘midgut volvulus’ resulting in serious clinical implications. The study was done to determine the frequency and degree of counterclockwise rotation of the SMV on SMA on CT in normal otherwise asymptomatic pediatric patients undergoing CT scan. Methods: In this IRB approved study, we retrospectively analyzed abdominal CT scan examinations of 200 consecutive pediatric patients (age range of 11 days to 18 years), which were performed for different clinical indications over a period of 10 months. They were evaluated for the absence or presence and degree of counterclockwise rotation of the mesenteric vessels. Results: Of the 200 patients, 128 (64%) patients showed no clockwise or anticlockwise rotation of mesenteric vessels. Counterclockwise rotation of SMV on SMA was seen in 72 (36%) patients. Further, the degree of rotation of vessels was also calculated, based on the criteria proposed by the authors. Conclusions: The counterclockwise rotation of SMV on SMA gives an appearance of mesenteric whirlpool in otherwise normal mesenteric vessels and can be misinterpreted as midgut volvulus. It is a normal CT appearance and is due to a variation in branching pattern of mesenteric vessels. Awareness of this normal branching pattern of mesenteric vessels is important to avoid an inadvertent laparotomy.

    Uterine leiomyomas are the most common pelvic tumor in women. Leiomyoma can show atypical locations and degenerations and may not be easily differentiated from adnexal masses. Uterine leiomyoma can undergo cystic degeneration and is said to be found in 4% of all types of degenerations. The commonest type of degeneration is hyaline seen in 60% of patients. Usually uterine leiomyoma does not present as clinical and radiological diagnostic challenge. However, when leiomyoma undergoes massive cystic degeneration they may become clinical and radiological diagnostic dilemmas. The MRI showed a huge cystic mass protruding up to the pelvis not differentiated from bilateral endometriomas and accompanying subserous myomas. Surgery revealed that the mass is not bilateral endometriomas but a huge pedunculated leiomyoma with cystic degeneration and cystic endometriosis. Endometriosis is a troubling gynecologic condition occurring in 10% to 15% of women of reproductive age and is associated with fertility problems. As a peritoneal disease, the locations of endometriotic lesions are predominantly the ovaries (96.4%), followed by the soft tissue (2.8%), gastrointestinal tract (0.3%), and urinary tract (0.2%) and other rare locations. The presented case is multiple sized cystic endometriosis (endometriomas) located in a huge pedunculated subserous leiomyoma in an infertile woman having a history of laparoscopic bilateral endometrioma surgery. Conclusion. To our knowledge, this is the first reported case for endometriotic cysts (endometriomas) located in a huge cystic degenerated leiomyoma. PubMed search revealed no report concerning endometriotic implantation in the leiomyomas.

  3. Rho kinase enhances contractions of rat mesenteric collecting lymphatics.

    Full Text Available The mechanisms that control phasic and tonic contractions of lymphatic vessels are poorly understood. We hypothesized that rho kinase ROCK, previously shown to increase calcium (Ca2+ sensitivity in vascular smooth muscle, enhances lymphatic contractile activity in a similar fashion. Contractions of isolated rat mesenteric lymphatic vessels were observed at a luminal pressure of 2 cm H2O in a 37°C bath. The expression of ROCK in isolated rat mesenteric lymphatic vessels was assessed by Western blotting and confocal microscopy. The role of ROCK in contractile function was tested using two specific yet structurally distinct inhibitors: H1152 (0.1-10 μM and Y-27632 (0.5-50 μM. In addition, lymphatics were transfected with constitutively active (ca-ROCK protein (2 μg/ml to assess gain of contractile function. Vessel diameter and the concentration of intracellular free Ca2+ ([Ca2+]i were simultaneously measured in a subset of isolated lymphatics loaded with the Ca2+-sensing dye fura-2. The results show expression of both the ROCK1 and ROCK2 isoforms in lymphatic vessels. Inhibition of ROCK increased lymphatic end diastolic diameter and end systolic diameter in a concentration-dependent manner. Significant reductions in lymphatic tone and contraction amplitude were observed after treatment 1-10 μM H1152 or 25-50 μM Y-27632. H1152 (10 μM also significantly reduced contraction frequency. Transient increases in [Ca2+]i preceded each phasic contraction, however this pattern was disrupted by either 10 μM H1152 or 50 μM Y-27632 in the majority of lymphatics studied. The significant decrease in tone caused by H1152 or Y-27632 was not associated with a significant change in the basal [Ca2+]i between transients. Transfection with ca-ROCK protein enhanced lymphatic tone, but was not associated with a significant change in basal [Ca2+]i. Our data suggest that ROCK mediates normal tonic constriction and influences phasic contractions in lymphatics. We

    Full Text Available Teratomas are the most common germ cell tumors among pediatric and female patients, which originates from germ cells layers and can be located everywhere in bodies. They are diagnosed by ultrasonography (US, which was characterized by calcification and cystic anechoic view. Our aim is to attract attention to a 21-year-old female patient with complaint of acute abdominal pain diagnosed with teratoma by early radiological imaging. The female patient admitted to the emergency department with a new onset of abdominal pain at the lower and left sides of the abdomen for a week. The suprapubic and left costovertebral angle tenderness were found in her physical examination. We firstly chose US for imaging. The US of the abdomen showed multiple cystic masses around uterus. Heterogeneous cystic and calcified lesions were detected on the patients computerized tomography scan, and considered as teratoma. A laparotomy was performed by gynecologists. At laparotomy, lobulated cystic masses were removed and the left ovary had been detorsioned. She has been discharged after two days of postoperative observation. For patients of young females with abdominal pain such as rare gynecological diseases, teratoma and ovarian torsion, in the emergency department should be considered and early imaging should be performed.

They are diagnosed by ultrasonography (US), which was characterized by calcification and cystic anechoic view. Our aim is to attract attention to a 21-year-old female patient with complaint of acute abdominal pain diagnosed with teratoma by early radiological im-aging. The female patient admitted to the emergency department with a new onset of abdominal pain at the lower and left sides of the abdomen for a week. The suprapubic and left costovertebral angle tenderness were found in her physical examination. We firstly chose US for imaging. The US of the abdomen showed multiple cystic masses around uterus. Heterogeneous cystic and calcified lesions were detected on the patients computerized tomography scan, and considered as teratoma. A laparotomy was per-formed by gynecologists. At laparotomy, lobulated cystic masses were removed and the left ovary had been detorsioned. She has been discharged after two days of postoperative observation. For patients of young females with abdominal pain such as rare gyneco-logical diseases, teratoma and ovarian torsion, in the emergency department should be considered and early imaging should be performed.

    Full Text Available Adenoid cystic carcinoma (ACC accounts for approximately 6-10% of all salivary gland tumors. Palatal minor salivary glands, parotid, and sub-mandibular glands are usually affected. Rarely, these lesions arising intraosseously have been reported. Mandible is commonly involved than maxilla. The present case is a giant ACC involving the right maxilla. A thorough clinical and radiographic evaluation was performed to assess the involvement of surrounding vital structures along with a meticulous metastatic work-up. Computed tomography showed a giant lesion in maxilla encroaching the left nasal fossa, antrum, buccal space, and oral cavity. No metastasis was noted. Histological evaluation from multiple sites showed both cribriform and solid patterns. Radiotherapy was given as patient did not comply for surgery. Though central ACC is extremely rare, especially in maxilla, it should be included in the differentials for lesions in maxilla. A prompt diagnosis with treatment and long-term follow-up is advised in such cases.

    Hepatocellular carcinoma (HCC) is a rapidly increasing cancer whose known risk factors are chronic ethanol abuse, viral hepatitis infection, and aflatoxin exposure. Obesity, an emerging HCC risk factor, is reaching epidemic proportions in developed nations. This study investigated the effects of diet-induced obesity (DIO) and chronic ethanol consumption on HCC progression in mice in vivo. In this study, C57BL/6 DIO mice and lean litter mates were maintained on a 60% (high-fat diet [HFD]) diet or a 10% (control diet [CD]) kcal% fat diet for 7 weeks before they were weaned to 10/20% ([v/v], alternating days) ethanol in drinking water (EtOH) or maintenance on drinking water (H(2)O) alone. Hepatic tumor formation was initiated by intrahepatic Hepa1-6 cell (6 × 10(6) cells) inoculation 6 weeks later via the mesenteric vein. The animals receiving the HFD showed decreased tumor incidence and area of hepatic foci versus the CD animals maintained on H(2)O alone. The action of EtOH suppressed tumor incidence further in both the CD and the HFD mice. Serologic analysis showed no significant differences in liver enzymes among the groups. Protein analysis demonstrated increased P450 2E1 (CYP2E1) in the groups maintained on EtOH, an effect exacerbated by HFD. Reverse transcriptase-polymerase chain reaction (RT-PCR) analysis demonstrated increased tumor necrosis factor-alpha (TNF-α) expression in HFD HCC mice (H(2)O and EtOH) concomitant with decreased transforming growth factor-beta (TGF-β) expression. Although obesity and EtOH consumption are known risk factors for HCC initiation and development, the data in this study suggest that these factors impair progression of established tumors within the liver.

    Intraperitoneal solid tumors are far less common in children than in adults, and the histologic spectrum of neoplasms of the peritoneum and its specialized folds in young patients differs from that in older patients. Localized masses may be caused by inflammatory myofibroblastic tumor, Castleman disease, mesenteric fibromatosis, or other mesenchymal masses. Inflammatory myofibroblastic tumor is a mesenchymal tumor of borderline biologic potential that appears as a solitary circumscribed mass, possibly with central calcification. Castleman disease is an idiopathic lymphoproliferative disorder that appears as a circumscribed, intensely enhancing mass in the mesentery. Mesenteric fibromatosis, or intra-abdominal desmoid tumor, is a benign tumor of mesenchymal origin associated with familial adenomatous polyposis. Mesenteric fibromatosis appears as a mildly enhancing, circumscribed solitary mass without metastases. Diffuse peritoneal disease may be due to desmoplastic small round cell tumor (DSRCT), non-Hodgkin lymphoma, or rhabdomyosarcoma. DSRCT is a rare member of the small round blue cell tumor family that causes diffuse peritoneal masses without a visible primary tumor. A dominant mass is typically found in the retrovesical space. Burkitt lymphoma is a pediatric tumor that manifests with extensive disease because of its short doubling time. The bowel and adjacent mesentery are commonly involved. Rhabdomyosarcoma may arise as a primary tumor of the omentum or may spread from a primary tumor in the bladder, prostate, or scrotum. Knowledge of this spectrum of disease allows the radiologist to provide an appropriate differential diagnosis and suggest proper patient management.

    Full Text Available AbstractIntroduction: Craniopharyngioma of childhood are commonly cystic in nature. An intracystic catheter insertion and subsequent instillation of substances inducing cyst shrinkage seems a beneficial strategy avoiding additional morbidity in a highly vulnerable brain location. Methods: A systematic review of the medical literature was performed to identify potentially relevant, all languages articles using Ovid MEDLINE and EMBASE from inception to July 2011 and Cochrane Central Register of Controlled Trials to 3rd quarter 2011. All references were examined for relevancy. Results: Of 142 unique references x referred to substances used for intracystic craniopharyngioma treatment. General aspects of intracystic catheter insertion as well as response rates, risks and outcomes of children treated with intracystic radio-isotopes, bleomycin and interferon are critically reviewed and an outline for potential future endeavours provided. Conclusions: Interferon seems currently the intracystic substance with the best benefit risk ratio. The authors advocate for consensus on prospective data collection and standardized intracystic treatment strategies to allow reliable comparisons and herewith optimize treatment and outcome.

  10. Cystic fibrosis: a clinical view.

    Cystic fibrosis (CF), a monogenic disease caused by mutations in the CFTR gene on chromosome 7, is complex and greatly variable in clinical expression. Airways, pancreas, male genital system, intestine, liver, bone, and kidney are involved. The lack of CFTR or its impaired function causes fat malabsorption and chronic pulmonary infections leading to bronchiectasis and progressive lung damage. Previously considered lethal in infancy and childhood, CF has now attained median survivals of 50 years of age, mainly thanks to the early diagnosis through neonatal screening, recognition of mild forms, and an aggressive therapeutic attitude. Classical treatment includes pancreatic enzyme replacement, respiratory physiotherapy, mucolitics, and aggressive antibiotic therapy. A significant proportion of patients with severe symptoms still requires lung or, less frequently, liver transplantation. The great number of mutations and their diverse effects on the CFTR protein account only partially for CF clinical variability, and modifier genes have a role in modulating the clinical expression of the disease. Despite the increasing understanding of CFTR functioning, several aspects of CF need still to be clarified, e.g., the worse outcome in females, the risk of malignancies, the pathophysiology, and best treatment of comorbidities, such as CF-related diabetes or CF-related bone disorder. Research is focusing on new drugs restoring CFTR function, some already available and with good clinical impact, others showing promising preliminary results that need to be confirmed in phase III clinical trials.

  11. Male fertility in cystic fibrosis.

    2011-04-05

    Infertility rates among males with cystic fibrosis (CF) approximate 97%. No information is currently available within Ireland determining an understanding of fertility issues and the best methods of information provision to this specialized group. This study aimed to determine understanding and preferred approaches to information provision on fertility issues to Irish CF males. A Descriptive Study utilizing prospective coded questionnaires was mailed to a male CF cohort (n=50). Sections included demographics, fertility knowledge & investigation. Response rate was 16\\/50 (32%). All were aware that CF affected their fertility. More than two-thirds (n=11) were able to provide explanations whilst only one-third (n=5) provided the correct explanation. Significant numbers stated thoughts of marriage and a future family. Half have discussed fertility with a healthcare professional (HCP). Mean age of discussion was 21.9 years. One third preferred an earlier discussion. The commonest first source for information was written material which was also the preferred source. Three-quarters requested further information preferring again, written material. Significant gaps in sex education of Irish CF males exist. Discussion should be initiated by HCPs and centre-directed written material devised to address deficiencies.

    Abdominal Cystic lymphangiomas (ACL) are uncommon benign masses usually presented during infancy. Although extremely rare, they may cause complications; therefore, the recommended therapy is surgical excision. The purpose of this study is to report our experience with the diagnosis and surgical treatment of ACL in pediatric population. From January 1994 to December 2009, 10 patients (6 females; 4 males) with diagnostic confirmation of ACL were retrospectively included in study. Children's age ranged between 9 months and 8 years (mean age at diagnosis was 2.5 years). Clinical presentation, cyst location, imaging studies employed, surgical approach and pathologic features were analyzed. The most common symptom was abdominal pain but three cases were incidentally detected. One case had presented with acute abdomen after traumatic haemorrhage of the tumor. All patients were diagnosed with ultrasonography as first-line radiological study. MRI was used in last three cases. At surgery, concomitant bowel resection was necessary in 3 children. Location of the lesion (omentum, mesentery) did not influence the outcome but surgery was more difficult (operative time over three hours) in patients with lymphangioma affecting mesentery of the jejunum. Mean hospital stay after surgery was 6.7 days. Mean follow-up was 5.1 years. No recurrence of the cystic lymphangioma was noticed during follow-up. One case developed an intestinal occlusion due to bowel adhesions 1 year after surgery. ACL usually affect infants and young children and may present with spectrum of symptoms from an incidental finding to an acute life-threatening abdominal obstruction. Complete excision of the tumor is a safe and effective method in the management of ACL in pediatric population. Surgery is mandatory to avoid potential complications.

    Carcinoid tumors are neoplasms with neuroendocrine differentiation, and they are most commonly found in the gastrointestinal and respiratory systems. Primary renal carcinoid tumor has rarely been reported. Here, we present a case of primary renal carcinoid tumor manifesting as a small but a gradually enhancing mass with calcification and a cystic component.

    Renal oncocytoma (RO) may present with a tubulocystic growth in 3% to 7% of cases, and in such cases its morphology may significantly overlap with tubulocystic renal cell carcinoma (TCRCC). We compared the morphologic and immunohistochemical characteristics of these tumors, aiming to clarify the differential diagnostic criteria, which facilitate the discrimination of RO from TCRCC. Twenty-four cystic ROs and 15 TCRCCs were selected and analyzed for: architectural growth patterns, stromal features, cytomorphology, ISUP nucleolar grade, necrosis, and mitotic activity. Immunohistochemical panel included various cytokeratins (AE1-AE3, OSCAR, CAM5.2, CK7), vimentin, CD10, CD117, AMACR, CA-IX, antimitochondrial antigen (MIA), EMA, and Ki-67. The presence of at least focal solid growth and islands of tumor cells interspersed with loose stroma, lower ISUP nucleolar grade, absence of necrosis, and absence of mitotic figures were strongly suggestive of a cystic RO. In contrast, the absence of solid and island growth patterns and presence of more compact, fibrous stroma, accompanied by higher ISUP nucleolar grade, focal necrosis, and mitotic figures were all associated with TCRCC. TCRCC marked more frequently for vimentin, CD10, AMACR, and CK7 and had a higher proliferative index by Ki-67 (>15%). CD117 was negative in 14/15 cases. One case was weakly CD117 reactive with cytoplasmic positivity. All cystic RO cases were strongly positive for CD117. The remaining markers (AE1-AE3, CAM5.2, OSCAR, CA-IX, MIA, EMA) were of limited utility. Presence of tumor cell islands and solid growth areas and the type of stroma may be major morphologic criteria in differentiating cystic RO from TCRCC. In difficult cases, or when a limited tissue precludes full morphologic assessment, immunohistochemical pattern of vimentin, CD10, CD117, AMACR, CK7, and Ki-67 could help in establishing the correct diagnosis.

    To report a case of superior mesenteric artery (SMA) syndrome secondary to hypothalamic germinoma. We describe the clinical presentation, diagnostic work-up, management, and clinical course of a patient admitted with SMA syndrome who was subsequently found to have a hypothalamic germinoma. An adolescent boy was admitted to the surgical ward with progressive weight loss over a 2 year period and postprandial vomiting. He was diagnosed with SMA syndrome based on evidence of proximal duodenal dilatation, extrinsic compression of the distal duodenum, and a narrowed aortomesenteric angle (16°). Investigations performed to exclude thyrotoxicosis unexpectedly revealed secondary hypothyroidism and further evaluation demonstrated evidence of pan-hypopituitarism. Psychiatric evaluation excluded anorexia nervosa and bulimia. Magnetic resonance imaging (MRI) of the brain revealed a heterogeneously enhancing hypothalamic lesion, but a normal pituitary gland. Hormone replacement with hydrocortisone, desmopressin, testosterone, and thyroxine resulted in weight gain and resolution of gastrointestinal symptoms. A transventricular endoscopic biopsy subsequently confirmed a hypothalamic germinoma and he was referred to an oncologist. SMA syndrome secondary to severe weight loss is an uncommon cause of upper gastrointestinal obstruction. While there have been reports of poorly controlled diabetes mellitus and thyrotoxicosis manifesting as SMA syndrome, there are no published reports to date of SMA syndrome secondary to hypothalamic/pituitary disease. Management of SMA syndrome is conservative, as symptoms of intestinal obstruction resolve with weight gain following treatment of the underlying cause. Awareness of this uncommon presentation of endocrine cachexia/hypothalamic disease will prevent unnecessary laparotomies and a misdiagnosis of an eating disorder.

    The aim of this study was to report on 8 patients with all different non-ischemic etiologies for portal-venous gas and to discuss this rare entity and its potentially misleading CT findings in context with a review of the literature. The CT examinations of eight patients who presented with intrahepatic portal-venous gas, unrelated to bowel ischemia or infarction, were reviewed and compared with their medical records with special emphasis on the pathogenesis and clinical impact of portal-venous gas caused by non-ischemic conditions. The etiologies for portal-venous gas included: abdominal trauma (n=1); large gastric cancer (n=1); prior gastroscopic biopsy (n=1); prior hemicolectomy (n=1); graft-vs-host reaction (n=1); large paracolic abscess (n=1); mesenteric recurrence of ovarian cancer superinfected with clostridium septicum (n=1); and sepsis with Pseudomonas aeruginosa (n=1). The clinical outcome of all patients was determined by their underlying disease and not negatively influenced by the presence of portal-venous gas. Although the presence of portal-venous gas usually raises the suspicion of bowel ischemia and/or intestinal necrosis, this CT finding may be related to a variety of non-ischemic etiologies and pathogeneses as well. The knowledge about these conditions may help to avoid misinterpretation of CT findings, inappropriate clinical uncertainty and unnecessary surgery in certain cases. (orig.)

    Mesenteric traction syndrome (MTS) consists of decreased systemic vascular resistance, increased cardiac output, facial flushing and palmar erythema. Local production of PGI2 is thought to be the cause. We experienced a rare case of MTS that occurred during coronary artery bypass graft surgery (CABG). A 64-year-old man was scheduled for CABG for the treatment of angina pectoris. Hemodynamic variables were stable until 50 minutes after surgical incision. Blood pressure fell down suddenly from 110/50 to 70/40 mmHg, accompanied by obvious facial flushing and palmar erythema, when the surgeons were preparing the right gastroepiploic artery. Hemodynamic changes and cutaneous hyperemia returned to the baseline level in about 40 minutes. After this episode, the operation was performed uneventfully. The time sequence between the onset of the surgical procedure and the hemodynamic and cutaneous findings strongly suggest the release of PGI2 and MTS. In patients undergoing CABG with the gastroepiploic artery graft, pretreatment with NSAID might avoid sudden circulatory changes of MTS.

    A retrospective review. To determine the incidence of the superior mesenteric artery syndrome (SMAS) after surgical correction for scoliosis and if it is influenced by newer derotation/translation surgical systems. The SMAS is a known complication after surgery. Of 2939 charts reviewed, 17 patients between 1960 and 2002 matched inclusion criteria. Our incidence of the SMAS was 0.5%. Onset of symptoms was 7.2 days. Several scoliosis diagnoses were included in the study group. Instrumentation that was used included: nondistraction systems (n = 14), Harrington rod with body cast (n = 1), Luque rod with sublaminar wires (n = 1), and casted in situ posterior spinal fusion (n = 1). Before surgery, 10 of 17 patients weighed less than the 50th percentile. Mean preoperative BMI was 18.6 kg/cm/cm. Postoperative height gain averaged 3.175 cm, and weight loss at onset of symptoms averaged 4.5 kg. There were 14 patients who required nasogastric suction for an average duration of 10.2 days, 11 required hyperalimentation, and 5 concurrently received hyperalimentation with enteric feeding. The SMAS recurred in 2 patients. Postoperative weight loss appears to be more important for the development of the SMAS than asthenic body type. Newer derotation/translation corrective techniques have not eliminated the SMAS. Gastrointestinal imaging is indicated when nausea and vomiting occur 6-12 days after surgery, associated with early satiety and normal bowel sounds. Decompression and nutritional support remain the mainstays of treatment.

    Posthemorrhagic shock mesenteric lymph (PHSML) is a key factor in multiple organ injury following hemorrhagic shock. We investigated the role of hydrogen sulfide (H2S) in PHSML drainage in alleviating acute kidney injury (AKI) by administering D,L-propargylglycine (PPG) and sodium hydrosulfide hydrate (NaHS) to 12 specific pathogen-free male Wistar rats with PHSML drainage. A hemorrhagic shock model was established in 4 experimental groups: shock, shock+drainage, shock+drainage+PPG (45 mg/kg, 0.5 h prehemorrhage), and shock+drainage+NaHS (28 µmol/kg, 0.5 h prehemorrhage). Fluid resuscitation was performed after 1 h of hypotension, and PHMSL was drained in the last three groups for 3 h after resuscitation. Renal function and histomorphology were assessed along with levels of H2S, cystathionine-γ-lyase (CSE), Toll-like receptor 4 (TLR4), interleukin (IL)-10, IL-12, and tumor necrosis factor (TNF)-α in renal tissue. Hemorrhagic shock induced AKI with increased urea and creatinine levels in plasma and higher H2S, CSE, TLR4, IL-10, IL-12, and TNF-α levels in renal tissue. PHSML drainage significantly reduced urea, creatinine, H2S, CSE, and TNF-α but not TLR4, IL-10, or IL-12. PPG decreased creatinine, H2S, IL-10, and TNF-α levels, but this effect was reversed by NaHS administration. In conclusion, PHSML drainage alleviated AKI following hemorrhagic shock by preventing increases in H2S and H2S-mediated inflammation.

    The relative importance of ATP as a functional sympathetic neurotransmitter in blood vessels has been shown to be increased when the level of preexisting vascular tone or pressure is increased, in studies carried out in rat mesenteric arteries. The aim of the present study was to determine whether tone influences the involvement of ATP as a sympathetic cotransmitter with noradrenaline in another species. We used the porcine perfused mesenteric arterial bed and porcine mesenteric large, medium and small arteries mounted for isometric tension recording, because purinergic cotransmission can vary depending on the size of the blood vessel. In the perfused mesenteric bed at basal tone, sympathetic neurogenic vasocontractile responses were abolished by prazosin, an α1-adrenoceptor antagonist, but there was no significant effect of α,β-methylene ATP, a P2X receptor-desensitizing agent. Submaximal precontraction of the mesenteric arterial bed with U46619, a thromboxane A2 mimetic, augmented the sympathetic neurogenic vasocontractile responses; under these conditions, both α,β-methylene ATP and prazosin attenuated the neurogenic responses. In the mesenteric large, medium and small arteries, prazosin attenuated the sympathetic neurogenic contractile responses under conditions of both basal and U46619-raised tone. α,β-Methylene ATP was effective in all of these arteries only under conditions of U46619-induced tone, causing a similar inhibition in all arteries, but had no significant effect on sympathetic neurogenic contractions at basal tone. These data show that ATP is a cotransmitter with noradrenaline in porcine mesenteric arteries; the purinergic component was revealed under conditions of partial precontraction, which is more relevant to physiological conditions.

    Full Text Available Abstract Background Visceral fat possesses the most detrimental potential for cardiovascular morbidity through the release of adipokines, as well as metabolic and proinflammatory mediators, which adversely affect metabolic and vascular homeostasis. Among the different types of visceral adipose tissue, mesenteric fat is considered particularly detrimental, due to its close proximity to the portal circulation, affecting directly the liver, which is the main regulator of body metabolic homeostasis. Mesenteric fat can be reliably estimated using abdominal ultrasonography, the only available imaging method able to depict individual mesenteric leaves. Aim of the present study was to investigate the correlation of mesenteric fat thickness (MFT with serum apolipoprotein levels in patients undergoing digital subtraction angiography in a single center. Methods 35 male patients with peripheral arterial disease were examined. After careful examination of the periumbilical area, the mesenteric leaves were identified. The maximal distance between each pair of sequential leaves was measured, and the mean value of the three thickest leaves was determined as the mesenteric fat thickness. Six apolipoprotein fasting serum concentrations were measured using a Luminex proteomics platform (xMAP Multiplex immunoassay: apolipoprotein A-I (apoAI, apolipoprotein A-II (apoAII, apolipoprotein B (apoB, apolipoprotein C-II (apoCII, apolipoprotein C-III (apoCIII and apolipoprotein E (apoE. Results MFT correlated with apoAII and apoB serum concentrations. The correlations with apoAII and apoB remained significant following correction for BMI. No correlations were noted between MFT and serum apoAI, apoCII, apoCIII or apoE levels before or after adjustment for BMI.

    The role of endogenous H2S has been highlighted as a gaseous transmitter. The vascular smooth muscle inhibitory effects of H2S have been characterized in isolated aorta and mesenteric arteries in rats and mice. Our study was aimed at investigating the vascular effects of H2S on human isolated mesenteric arteries and examining the underlying mechanisms involved. All experiments were performed on rings (4-8mm long) of human mesenteric arteries obtained from patients undergoing abdominal surgery. Ethical approval was obtained from the Ethics Committee of the University Hospital of the University of Florence (app. N. 2015/0024947). The effect of NaHS, an H2S donor, was determined using noradrenaline pre-contracted human isolated mesenteric rings. NaHS evoked a concentration-dependent relaxation (EC50 57μM). In contrast, homocysteine, an endogenous precursor of H2S, failed to affect human isolated mesenteric rings. Vasorelaxant response to NaHS was reduced by endothelium removal, application of the nitric oxide synthase inhibitor L-NAME and ODQ inhibitor of cyclic GMP. SQ 22536, an adenylate-cyclase inhibitor, failed to block NaHS-induced vasorelaxation. Inhibition of endogenous prostanoid production by indomethacin significantly reduced NaHS induced vasorelaxation. The role of potassium channels was also examined: blockers of the Ca(2+)-dependent potassium channel, charybdotoxin and apamin, failed to have any influence on the relaxant response to NaHS on this vascular tissue. In summary, H2S induced relaxation of isolated rings of human mesenteric arteries. Endothelium-dependent related mechanisms with the stimulation of ATP-sensitive potassium channels represents important cellular mechanisms for H2S effect on human mesenteric arteries.

    Brenner tumor is a rare tumor that represents approximately 1.5% of the tumors of ovary. It is defined as a tumor of transitional cells composed by urothelial cells arranged in solid or cystic groups absorbed in a fibrous stroma. It classifies in benign Brenner tumor (95%), borderline (3-4%) and malignant (1%). Let's sense beforehand the clinical case of a 46-year-old patient who underwent surgery having an adnexal mass of which the pathological intraoperative report brought a benign Brenner tumor.

    Enteric duplication cysts presenting in adulthood are rare. Isolated enteric duplication cysts, which lack a connection to the GI tract or the adjacent mesenteric vasculature, have only been cited in six previous case reports. A 48-year-old female presented with a four-year history of intermittent nausea, vomiting and abdominal pain. Computed tomography (CT) scan of the abdomen revealed a 7cm multi-lobular, calcified, cystic lesion intimately involved with the pancreas. Endoscopic ultrasound (EUS)-guided fine-needle aspiration (FNA) was non-diagnostic; however, the cyst fluid Carcinoembryonic Antigen (CEA) level was significantly elevated leading to a presumed diagnosis of a mucinous cystic neoplasm (MCN) of the pancreas. Intraoperatively, the cystic mass was identified and notably did not have any true attachments to the neighboring pancreas, gastrointestinal tract or vasculature. Final pathology demonstrated an isolated small bowel duplication cyst. In this case a patient presented with a clinical picture consistent with an MCN of the pancreas. However, intraoperatively and on final pathology the mass was found to be an isolated enteric duplication cyst. This represents only the seventh such case report in an adult. Although rare, isolated enteric duplication cysts can be considered in a patient presenting with chronic abdominal pain and an abdominal mass on imaging. In this case we demonstrate that an isolated enteric duplication cyst can clinically mimic an MCN of the pancreas. Copyright © 2017 The Author(s). Published by Elsevier Ltd.. All rights reserved.

    2015-02-01

    Due to increasing utilization of cross-sectional imaging, asymptomatic pancreatic cysts are frequently being diagnosed. Many of these cysts have premalignant potential and offer a unique opportunity for cancer prevention. Mucinous cystic neoplasm and intraductal papillary mucinous neoplasm are the major premalignant cystic neoplasms of pancreas. The prediction of the risk of malignancy (incidental and future risk of malignant transformation) and balancing the risks of watchful waiting with that of operative management with associated mortality and morbidity is the key to the management of these lesions. We review the literature that has contributed to the development of our approach to the management of these cystic neoplasms. We provide an overview of the key features used in diagnosis and in predicting malignancy. Particular attention is given to the natural history and management decision making.

    The aim of this retrospective, population-based study was to characterize demographically and clinically cystic-echinococcosis (CE) in southern Israel, between 2005 and 2012. Newly-diagnosed (nd-CE) and past-diagnosed (pd-CE, diagnosed before the study) cases were defined. Two populations live in southern-Israel, receiving medical treatment at a single hospital: the Jewish and the Bedouin populations (resembling resource-rich and resource-poor populations, respectively). 126 CE cases were identified; 55 nd-CE and 71 pd-CE. Mean annual nd-CE incidence per 100,000 in the Bedouin and Jewish populations were 2.7 ± 1.2 and 0.4 ± 0.3, respectively (Pborn outside Israel. Liver and lung involvement were recorded in 85.7% and 15.1% of overall-CE, respectively. Abdominal pain, cough, fever, eosinophilia and asymptomatic disease were documented in 63.6%, 32.7%, 27.3%, 41.5% and 12.7% of nd-CE, respectively. Serology sensitivity for first test and any positive test were 67.3% and 83.3%, respectively. Computed tomography, ultrasonography and X-ray diagnosis were documented in 79.2%, 58.4% and 17.0% of overall-CE, respectively, with ultrasonography mainly used in liver-CE and X-ray in lung-CE. Treatment included surgery and albendazole in 50.0% and 55.3% of CE, respectively. We conclude that CE is endemic in southern-Israel among the Bedouin population, while disease is probably mainly imported in the Jewish population. Liver involvement and eosinophilia rates were high compared with those of other endemic regions, possibly due to differences in the timing of diagnosis. These findings may help developing treatment and prevention strategies.

    Full Text Available Giant ovarian cysts in adolescents are very rare. Those treatment by laparotomy or laparoscopic surgery is discussed with gynecologists and pediatric surgeons because its limited working space and risk of rupture and malignancy. We present a case of minimal laparotomy management of a giant ovarian cystic teratoma in adolescent. A 13-year-old girl presented with abdominal pain and constipation. A CT scan showed a giant simple ovarian cystic tumor in her abdomen measuring 29 × 13 × 24 cm. We made a 3-cm Pfannenstiel incision and inserted an Alexis wound retractor XS. The cyst was completely aspirated without spillage in the intraperitoneal space. In total, 6L of murky brown fluid was aspirated from the cyst. There was no ovarian tissue visible on the cyst wall. The left tube and right ovary and tube were intact. The cyst wall and left ovary tube were dissected free by using a LigaSure. Postoperative recovery was uneventful. Pathological assessment revealed a mature cystic teratoma. The ovarian tissue was included in the part of the cyst wall. We were able to safely perform with minimal laparotomy. Therefore, we consider the for cases of giant ovarian tumors, minimal laparotomy surgery is useful from the safety and cosmetic perspective.

    Full Text Available The occurrence of malignancies in somatic elements of mature cystic teratoma of ovary is rare. The malignancies that may be encountered in dermoid cyst include squamous cell carcinoma, adenocarcinoma, adenosquamous carcinoma, melanoma, sarcoma, carcinoid, and germ cell neoplasms. The development of transitional cell carcinoma (TCC in dermoid cyst is extremely rare with only four such cases having been reported in literature so far. Here we report the fifth case of such an occurrence in a 50-year-old postmenopausal multiparous female patient. She presented with pain and gradual swelling of abdomen for 1 month. Abdominal computed tomography revealed a solid space occupying lesion with few cystic components at right pelvis, raising the possibility of an ovarian neoplasm. The level of CA-125 was slightly raised (56∙45 U/ml. Total abdominal hysterectomy and bilateral salpingo-oopherectomy was performed. Microscopic examination showed cyst wall lined by stratified squamous epithelium. Beneath the cyst wall, a tumor mass was present, histological features of which resembled that of high-grade TCC (stage pT1aNXMX. On immunohistochemical analysis, the tumor was found to be positive for CK7 and CK20 and negative for WT-1. These results were consistent with a diagnosis of TCC arising in urothelium of mature cystic teratoma. Reporting of such extremely rare cases is important for the assessment of prognostic factors and treatment protocols.

    2015-02-01

    Borderline resectable (BR) pancreatic cancer involves the portal vein and/or superior mesenteric vein (PV/SMV), major arteries including the superior mesenteric artery (SMA) or common hepatic artery (CHA), and sometimes includes the involvement of the celiac axis. We herein describe tips and tricks for a surgical technique with video assistance, which may increase the R0 rates and decrease the mortality and morbidity for BR pancreatic cancer patients. First, we describe the techniques used for the "artery-first" approach for BR pancreatic cancer with involvement of the PV/SMV and/or SMA. Next, we describe the techniques used for distal pancreatectomy with en-bloc celiac axis resection (DP-CAR) and tips for decreasing the delayed gastric emptying (DGE) rates for advanced pancreatic body cancer. The mesenteric approach, followed by the dissection of posterior tissues of the SMV and SMA, is a feasible procedure to obtain R0 rates and decrease the mortality and morbidity, and the combination of this aggressive procedure and adjuvant chemo(radiation) therapy may improve the survival of BR pancreatic cancer patients. The DP-CAR procedure may increase the R0 rates for pancreatic cancer patients with involvement within 10 mm from the root of the splenic artery, as well as the CHA or celiac axis, and preserving the left gastric artery may lead to a decrease in the DGE rates in cases where there is more than 10 mm between the tumor edge and the root of the left gastric artery. The development of safer surgical procedures is necessary to improve the survival of BR pancreatic cancer patients. © 2014 Japanese Society of Hepato-Biliary-Pancreatic Surgery.

    Carvacrol (CRV) has strong cytoprotective, antioxidant, and anti-inflammatory properties. We aimed to demonstrate the possible protective effects of CRV on survival, mesenteric artery blood flow (MBF), vascular reactivity, and oxidative and inflammatory injuries in a murine model of polymicrobial sepsis induced by cecal ligation and puncture (CLP). Wistar rats were allocated into the following four groups: Sham, CLP, Sham + CRV, and CLP + CRV. The animals were orally administered with CRV (80 mg/kg/day) or vehicle (corn oil; 1 mL/kg/day) for 7 days. At the eighth day, Sham or CLP procedure was applied. Twenty hours after the operations, MBF and contractile responses of isolated aortic preparations to phenylephrine were measured. Tissue samples were obtained for biochemical and histopathological assessments. Additionally, survival rates were recorded throughout 96 h. CRV administration improved the mesenteric perfusion, contractile function of aorta, and survival after CLP. CRV substantially prevented the elevations in the levels of LDH, BUN, Cr, and inflammatory cytokines (tumor necrosis factor-alpha, interleukin-1 beta and interleukin-6) but could not prevent the elevations of AST and ALT after CLP. The decreased liver, kidney, and spleen glutathione levels and increased liver, kidney, lung, and spleen malondialdehyde levels induced by CLP were substantially restored by CRV. Also, histopathological protective effects of CRV on multiple organ damage due to CLP were observed. CRV possesses strong ameliorative effects on sepsis due to its protective effects on mesenteric perfusion and aortic function and its antioxidative and anti-inflammatory effects.

  18. Pyelo-cystic Reflux in F-18 FDG PET Scan Due to Ureteral Obstruction

    Reyhan, Mehmet [Baskent Univ., Adana (Turkmenistan)

    2013-09-15

    A 72-year-old woman with a history of cervical cancer was treated with brachytherapy and chemotherapy. Combined F-18 FDG PET/CT performed for restaging demonstrated increased FDG uptake in a hypodense cystic lesion at the posterior part of the right renal cortex and a hypermetabolic soft tissue mass at the right parailiac region suggestive of a metastatic lymph node causing ureteral obstruction. There had been no FDG uptake in the cystic lesion on the FDG PET/CT study performed 1 year before. These findings suggest that the increased FDG uptake in the cystic lesion was caused by pyelocystic reflux due to ureteral obstruction secondary to parailiac lymph node metastasis (Figs. 1 and 2). Several renal lesions may have increased metabolism, such as renal cell carcinoma, lymphoma, oncocytoma, adult Wilms' tumor, angiomyolipoma, metastatic lesions, xanthogranulo-matous pyelonephritis and infected cyst. Most of these lesions are solid. Some infected renal cysts may be FDG avid, but in this situation increased FDG uptake is observed on the wall of the cyst. In our case, FDG uptake was seen in the entire cystic lesion. The patient had no symptoms or laboratory findings related to infection. Cysts are the most common space-occupying lesions of the kidney. The vast majority of these are simple cysts that are usually unilateral and solitary. Simple cysts are asymptomatic, except when complications exist such as hemorrhage, infection or rupture. There have been a few reports on spontaneous communications between renal cysts and the pyelocaliceal system, in most cases involving ruptures of the cysts into the pyelocaliceal system due to increased intracystic pressure caused by bleeding or infection of the cyst. In the present case, the cause of the connection between the cystic cavity and the pyelocaliceal system is the increased pressure in the renal pelvic cavity due to the ureteral obstruction secondary to parailiac lymph node metastasis.

    Cystic fibrosis (CF) is a common life-shortening autosomal recessive genetic disorder caused by mutations in the gene that encodes for the cystic fibrosis transmembrane conductance regulator protein (CFTR). Almost 2000 variants in the CFTR gene have been identified. The mutational classes are based on the functional consequences on CFTR. New therapies are being developed to target mutant CFTR and restore CFTR function. Understanding specific CF genotypes is essential for providing state-of-the art care to patients. In addition to the variation in CFTR genotype, there are several modifier genes that contribute to the respiratory phenotype.

    The diagnosis of cystic fibrosis (CF) is being made with increasing frequency in adults. Patients with CF diagnosed in adulthood typically present with respiratory complaints, and often have recurrent or chronic airway infection. At the time of initial presentation individuals may appear to have clinical manifestation limited to a single organ, but with subclinical involvement of the respiratory tract. Adult-diagnosed patients have a good response to CF center care, and newly available cystic fibrosis transmembrane receptor-modulating therapies are promising for the treatment of residual function mutation, thus increasing the importance of the diagnosis in adults with unexplained bronchiectasis.

    The cystic fibrosis transmembrane conductance regulator (CFTR) protein is highly expressed in the pancreatic duct epithelia and permits anions and water to enter the ductal lumen. This results in an increased volume of alkaline fluid allowing the highly concentrated proteins secreted by the acinar...... cells to remain in a soluble state. This work will expound on the pathophysiology and pathology caused by the malfunctioning CFTR protein with special reference to ion transport and acid-base abnormalities both in humans and animal models.

    2016-12-01

    Full Text Available Subependymomas are a rare subtype of ependymomas, slow growing WHO grade I tumors that develop either intracranial from the subependymal glial precursor cells layer of the ventricles or intramedullary. These tumors originate in the undifferentiated Subependymal layer of cells that can become either ependymocytes or astrocytes. Most of the subependymomas are located inside the fourth ventricle (50-60%. We reviewed the case of a 40 years old woman with a giant solid cystic fourth ventricle ependymoma. The patient underwent total resection of the tumor through a subociipital transvermian approach. We discussed the characteristics of these benign tumors and reviewed the literature on this subject and concluded that total resection is the treatment of choice for symptomatic Subependymomas localized in posterior fossa.

    Objectives: To investigate the relation between metastatic potential of salivary adenoid cystic carcinoma (SACC) and tumor cell-platelet adhesion, and the antimetastatic effect of integrin IIb/IIIa inhibitor on SACC. Methods: Tumor cell-platelet adhesion of highly metastatic SACC-LM, non-highly metastatic SACC-83 and effect of aspirin, arginine-aspartate (RD), magnesium acetylsalicylate on adhesion were studied in vitro. Antimetastafic effect of aspirin, RD, magnesium acetysalicylate on experimental metastasis of SACC was observed in vivo. Results: The tumor cell-platelet adhesion was stronger in SACC-LM than in SACC-83. Aspirin, RD and magnesium acetylsalicylate could inhibit the adhesion of SACC-LM at the concentration of 1, 5 and 25 mg/ml. RD can inhibit experimental metastasis of SACC. Conclusion: Metastasis of SACC is related to platelet-tumor cell adhesion, RD could inhibit metastasis of SACC.

Methods: From 2 646 female patients underwent breast sonography at King Chulalongkorn Memorial Hospital from January 2005 through December 2010, 103 cystic lesions were included. Pathologic confirmation was performed by fine-needle aspiration (n=42, core needle biopsy (n=6, excision (n=54 and mastectomy (n=1. Complex cystic breast masses were classified into 3 types as followings; thick outer wall and/or thick internal septa (type I; thick septation and thick wall were defined as equal or more than 0.5 cm, masses containing mixed cystic and solid components (at least 50% of cystic component (type II, predominantly solid with eccentric cystic foci (at least 50% of solid component (type III. Results: In 103 complex cystic masses, there are 27 lesions (26% classified as type I cystic breast masses, 37 lesions (36% as type II cystic breast masses and 39 lesions (38% type III cystic breast masses, 26 lesions (25.2% are proved to be malignant. All of type I cystic breast masses in our study are benign, and 14 (38% of type II cystic breast masses and 12 lesions (31% of type III cystic breast lesions are proved to be malignant. Conclusions: Type II and III lesions should suggest possibility of malignancy and biopsy should be performed in all lesions. All type I lesion in this study are benign. None of other parameters we included in this study (size or margin can effectively differentiate between benign or malignant cystic breast lesions. Also, grading of the malignant lesions by using type of cystic breast mass cannot be applied.

    The Zenith (Cook Medical, Bloomington, Ind) fenestrated endovascular graft may be designed with single-wide scallops or large fenestrations to address the superior mesenteric artery (SMA). Misalignment of the SMA with an unstented scallop or a large fenestration is possible. This study assessed SMA outcomes after fenestrated endovascular aortic aneurysm repair (FEVAR). During an 18-month period, 47 FEVARs were performed at a single institution. For analysis, patients were grouped according to unstented (n = 23) vs stented (n = 24) SMA scallops/fenestrations. The Institutional Review Board approved this single-institution observational study. Because this was a retrospective review of the data, patient consent was unnecessary for the study. Technical success for FEVAR was 100%. The median follow-up period was 7.7 months (range, 1-16 months). Nine of 21 patients (43%) in the unstented group had some degree of misalignment of the SMA (range, 9%-71%). Among these, four patients (44%) developed complications: three SMA stenoses and one occlusion. The mean peak systolic velocity in patients with and without SMA misalignment was 317.8 cm/s vs 188.4 cm/s (P < .08), respectively. No misalignment occurred in the stented group, and only one of 19 patients (5%) developed an SMA stenosis that required angioplasty. Overall, patients with unstented SMAs had significantly more adverse events directly attributable to SMA misalignment than the stented group (44% vs 5%, respectively; P < .05). Misalignment of the SMA with the use of unstented unreinforced scallops or fenestrations occurs frequently. Routine stenting of single-wide and large fenestrations, when feasible, may be a safer option for patients undergoing FEVAR. Copyright © 2016 Society for Vascular Surgery. Published by Elsevier Inc.

    2017-09-30

    Guanylyl cyclase C (GC-C) is a member of a family of enzymes that metabolize GTP to cGMP and was first identified as a receptor for heat-stable enterotoxin. Guanylin (GNY) has since been identified as an endogenous ligand for GC-C in the intestine of several mammalian species. The GNY/GC-C system regulates ion transportation and pH in the mucosa. Recently, it was reported that GC-C and GNY are involved in lipid metabolism in rat mesenteric adipose tissue macrophages. To examine the role of GC-C and GNY in lipid metabolism in cattle, we used a bovine mesenteric adipocyte primary culture system and a coculture system for bovine adipocytes and GNY-/GC-C-expressing macrophages. Fat droplets were observed to accumulate in bovine mesenteric adipocytes cultured alone, whereas few fat droplets accumulated in adipocytes indirectly cocultured with macrophages. We also observed that GC-C was present in bovine mesenteric adipose tissue, and that fat droplet accumulation decreased after in vitro GNY administration. Expressions of mRNAs encoding lipogenic factors decreased significantly in adipocytes after either coculture or GNY administration. These results suggest that the GNY/GC-C system is part of the control system for lipid accumulation in bovine mesenteric adipose tissue.

  8. The role of prostacyclin in the mesenteric traction syndrome during anesthesia for abdominal aortic reconstructive surgery.

    Mesenteric traction syndrome consists of sudden tachycardia, hypotension, and cutaneous hyperemia, and frequently occurs during mesenteric traction in patients undergoing abdominal aortic aneurysm (AAA) reconstructive surgery. The etiology and clinical impact of this phenomenon are unknown, but the symptoms suggest a release of vasoactive materials from the mesenteric vascular bed. Thirty-one patients who underwent AAA surgery were studied. Mesenteric traction was accompanied by a decrease in systolic (p = 0.005) and diastolic (p less than 0.05) blood pressures, and in systemic vascular resistance (p less than 0.005), and was accompanied by an increase in heart rate (HR) (p less than 0.005), and cardiac output (p = 0.01). These hemodynamic changes coincided with an increase (p less than 0.001) in plasma concentrations of 6-keto-prostaglandin F1 (6-K-PGF1). No apparent change was found in prostaglandin E2, thromboxane B2, and histamine concentrations. The concentration of 6-K-PGF1 was correlated with diastolic blood pressure (r = -0.52, p less than 0.005) and HR (r = 0.65, p less than 0.001). Cutaneous hyperemia was observed in 58% of the patients. In an additional six patients, who had taken aspirin daily before AAA surgery, no significant changes were observed in the hemodynamic measurements or 6-K-PGF1 concentrations. These data suggest that mesenteric traction syndrome may be mediated at least in part by a selective release of prostacyclin.

    Full Text Available OBJECTIVE: Resistance vessel remodeling is controlled by myriad of hemodynamic and neurohormonal factors. This study characterized structural and molecular remodeling in mesenteric resistance arteries (MRAs in diabetic (db/db and control (Db/db mice. METHODS: Structural properties were assessed in isolated MRAs from 12 and 16 wk-old db/db and Db/db mice by pressure myography. Matrix regulatory proteins were measured by Western blot analysis. Mean arterial pressure and superior mesenteric blood flow were measured in 12 wk-old mice by telemetry and a Doppler flow nanoprobe, respectively. RESULTS: Blood pressure was similar between groups. Lumen diameter and medial cross-sectional area were significantly increased in 16 wk-old db/db MRA compared to control, indicating outward hypertrophic remodeling. Moreover, wall stress and cross-sectional compliance were significantly larger in diabetic arteries. These remodeling indices were associated with increased expression of matrix regulatory proteins matrix metalloproteinase (MMP-9, MMP-12, tissue inhibitors of matrix metalloproteinase (TIMP-1, TIMP-2, and plasminogen activator inhibitor-1 (PAI-1 in db/db arteries. Finally, superior mesenteric artery blood flow was increased by 46% in 12 wk-old db/db mice, a finding that preceded mesenteric resistance artery remodeling. CONCLUSIONS: These data suggest that flow-induced hemodynamic changes may supersede the local neurohormonal and metabolic milieu to culminate in hypertrophic outward remodeling of type 2 DM mesenteric resistance arteries.

    Objective Resistance vessel remodeling is controlled by myriad of hemodynamic and neurohormonal factors. This study characterized structural and molecular remodeling in mesenteric resistance arteries (MRAs) in diabetic (db/db) and control (Db/db) mice. Methods Structural properties were assessed in isolated MRAs from 12 and 16 wk-old db/db and Db/db mice by pressure myography. Matrix regulatory proteins were measured by Western blot analysis. Mean arterial pressure and superior mesenteric blood flow were measured in 12 wk-old mice by telemetry and a Doppler flow nanoprobe, respectively. Results Blood pressure was similar between groups. Lumen diameter and medial cross-sectional area were significantly increased in 16 wk-old db/db MRA compared to control, indicating outward hypertrophic remodeling. Moreover, wall stress and cross-sectional compliance were significantly larger in diabetic arteries. These remodeling indices were associated with increased expression of matrix regulatory proteins matrix metalloproteinase (MMP)-9, MMP-12, tissue inhibitors of matrix metalloproteinase (TIMP)-1, TIMP-2, and plasminogen activator inhibitor-1 (PAI-1) in db/db arteries. Finally, superior mesenteric artery blood flow was increased by 46% in 12 wk-old db/db mice, a finding that preceded mesenteric resistance artery remodeling. Conclusions These data suggest that flow-induced hemodynamic changes may supersede the local neurohormonal and metabolic milieu to culminate in hypertrophic outward remodeling of type 2 DM mesenteric resistance arteries.

    Full Text Available The effect of dopamine on cyclic AMP levels in tissue slices of canine myocardium and kidney, and in chopped superior mesenteric arterial wall was investigated to identify dopamine receptors. Tissues were incubated in modified Krebs-Henseleit Ringer bicarbonate solution at 37 degrees C for 20 min with test drugs, after 20-min preincubation. In the presence of 3-isobutyl-1-methylxanthine (IBMX, dopamine and apomorphine caused dose-dependent increases in cyclic AMP levels in the myocardium, kidney and superior mesenteric artery. Phentolamine significantly intensified the cyclic AMP-increasing effect of dopamine in the superior mesenteric artery, but it did not influence the cyclic AMP increase caused by dopamine or apomorphine in the myocardium and kidney. Propranolol markedly blocked the effect of dopamine on cyclic AMP levels in all tissues studied. Haloperidol slightly inhibited the effect of dopamine and completely blocked the effect of apomorphine in the myocardium and kidney. These data suggest that dopamine increases cyclic AMP levels by activating predominantly beta-adrenergic receptors and partly dopamine receptors in the canine myocardium, kidney and superior mesenteric artery. The present results also suggest that dopamine acts not only on beta-adrenergic and dopamine receptors but also on alpha-adrenergic receptors in the superior mesenteric artery. Contrary to the activation of beta-adrenergic and dopamine receptors, the activation of alpha-adrenergic receptors resulted in a decrease in cyclic AMP levels in this tissue.

    Palatal tumors commonly arise from the minor salivary glands, and benign tumors account for approximately half of all minor salivary gland tumors. Minor salivary gland tumors have an affinity for the posterior hard palate and soft palate and virtually never arise in the midline, probably because of the distribution of palatal salivary glands. The majority of benign salivary gland tumors of the palate are pleomorphic adenomas, while the most common malignant salivary gland tumor is adenoid cystic carcinoma, followed by mucoepidermoid carcinoma, adenocarcinoma, and polymorphous low-grade adenocarcinoma. Epithelial tumors frequently arise from the soft palate. The majority of benign epithelial tumors of the palate are papillomas, while most malignant epithelial tumors are squamous cell carcinomas. Various types of mesenchymal tumors, including fibromas, lipomas, schwannomas, neurofibromas, hemangiomas, and lymphangiomas, also involve the palate. This article describes the CT and MR findings of benign and malignant palatal tumors.

  13. Cystic Eccrine Spiradenoma of the Finger Mimicking a Ganglion

    2014-01-01

    Full Text Available Summary: We report a rare case of cystic eccrine spiradenoma in the finger. A 46-year-old man presented with a cystic mass in his left index finger. Clinical assessment along with the investigation pointed toward a diagnosis of a ganglion. However, excisional biopsy of the mass revealed histopathological findings of cystic eccrine spiradenoma. Very few cases of eccrine spiradenoma have been reported in the hand and none of them were cystic in consistency. We believe that this case will draw the surgeon’s attention to the possibility of unusual differential diagnoses in the evaluation and treatment of cystic lumps in the hand.

    BACKGROUND:Spontaneous hemoperitoneum of hepato-biliary origin is commonly due to hemorrhage from a liver tumor. It is rarely caused by spontaneous rupture of aneurysm in visceral arteries. METHODS:We report an unusual case of hemoperitoneum caused by rupture of cystic artery pseudoaneurysm, and also outline the approach to its management through surgical and radiological methods. RESULTS:In our patient, the pseudoanurysm was initially treated with percutaneous thrombin injection. However this method of treatment failed after initial success. The pseudoanurysm was ifnally obliterated successfully using microcoil embolization. CONCLUSIONS: The mainstay of treatment of cystic artery pseudoaneurysm is cholecystectomy and ligation of the aneurysm. Recent publications showed success in using microcoil embolisation. In this case we also outline the use of percutaneous thrombin injection as a deifnitive treatment method and discuss its success or failure as a new method of treatment.

    We present four cases of cystic lymphagioma (CL) confirmed by pathoanatomic tests. The first, cervicothoracic, in a neonate in whom echography raised suspicion of an intrauterine localization. The second, in a male aged 17, right laterocervical, with recurrence in mediastinus. Another one in a woman aged 30 suffering from cervicothoracic and abdominal damage. Finally, another woman aged 36 with pure mediastinal CL. Patients presented with nonspecific symptomatology. Simple radiographies showed well delimited ''water''-dense tumoral masses and in only one case was displacement of mediastinal structures found. By echography CL were observed to have cystic features, with interior septa, By CT it was confirmed that the lesion was well delimited, sometimes enclosed in a capsula and presented low density homogeneous composition. The lesion itself to the neighboring structures rather that displace them. By angiography we could observe that mass was avascular and displaced normal vessels (Author)

    To assess left ventricular systolic and diastolic function in adult patients with cystic fibrosis using radionuclide ventriculography. Although myocardial fibrosis has been described in autopsy specimens of patients with cystic fibrosis, the possibility that myocardial dysfunction may occur during life in adult patients with cystic fibrosis has not been explored. To assess the possibility of cardiac dysfunction occurring in cystic fibrosis, we studied 40 patients with advanced cystic fibrosis with first-pass radionuclide ventriculography and compared them to 9 patients with advanced bronchiectasis and 18 normal control subjects. Indexes of right ventricular systolic function were similarly impaired in patients with cystic fibrosis and patients with bronchiectasis. Left ventricular ejection fraction of patients with cystic fibrosis, patients with bronchiectasis, and normal control subjects did not differ. Fractional left ventricular filling at 50% of diastole, an index of diastolic function, was significantly lower in patients with cystic fibrosis (54 +/- 13%, mean +/- SD) in comparison to patients with bronchiectasis (66 +/- 4%, p = 0.009) or normal control subjects (69 +/- 14, p = 0.0002). The contribution of atrial systole to total diastolic left ventricular filling was greater in patients with cystic fibrosis (38 +/- 18%) than in patients with bronchiectasis (21 +/- 4%, p = 0.01) or normal control subjects (25 +/- 12%, p = 0.01). Patients with advanced cystic fibrosis demonstrate impaired left ventricular distensibility when compared to normal control subjects and patients with bronchiectasis. Patients with cystic fibrosis may be at risk of heart failure due to right ventricular dysfunction or left ventricular diastolic dysfunction.

  19. Peripartum Ultrasound-Guided Drainage of Cystic Fetal Sacrococcygeal Teratoma for the Prevention of the Labor Dystocia: A Report of Two Cases

    Directory of Open Access Journals (Sweden)

    Vedran Stefanovic

    2011-12-01

    Full Text Available Fetal sacrococcygeal teratoma (SCT is the most common tumor in the neonatal period and is easily detected by modern ultrasound techniques, mostly during the second-trimester screening. It can cause significant fetal/neonatal morbidity and mortality due to its size, vascular loading, possible rupture, and labor dystocia. Mostly cystic teratomas have favorable prognosis, but if untreated in utero, they may rupture or cause labor obstruction. Cesarean delivery, especially with the vertical incision, increases significantly maternal morbidity due to the hemorrhage and the risk of the uterine rupture in the subsequent pregnancies. The authors report in details two SCT cases with uncomplicated vaginal delivery after peripartum ultrasound-guided drainage of the cystic teratoma. We conclude that the percutaneous emptying of the cystic SCT is an easy, encouraging, safe, and efficient procedure and enables normal vaginal delivery, thus avoiding labor dystocia and possible complications of the cesarean delivery and the risk of tumor rupture.

  20. Cranial Mesenteric Arterial Obstruction Due To Strongylus vulgaris Larvae in a Donkey (Equus asinus.

    Full Text Available Arteritis due to Strongylus vulgaris is a well-known cause of colic in horses and donkeys. The current report describes a fatal incidence of arterial obstruction in cranial mesenteric artery caused by S. vulgaris infection in an adult donkey in which anthelmintic treatment was not regularly administered. Necropsy findings of the abdominal cavity revealed a complete cranial mesenteric arterial obstruction due to larvae of S. vulgaris, causing severe colic. To the authors' knowledge, a complete cranial mesenteric arterial obstruction due to verminous arteritis has rarely been described in horses and donkeys. Based on recent reports of fatal arterial obstruction due to S. vulgaris infection in donkeys, it may be evident to consider acute colic caused by this pathogenic parasite a re-emerging disease in donkeys and horses.

    Full Text Available Disseminated tuberculosis in HIV infection involves multiple organs. Pulmonary and lymph node involvement are the commonest form of tuberculosis in HIV infection [1, 2]. Other forms of tuberculosis in the absence of lung and lymph node involvement are rare. Various forms of abdominal [3, 4] and neurological [5, 6] tubercular involvement in HIV infection have been reported. But tuberculosis presenting simultaneously with mesenteric and brain abscess has not been reported yet. We report a case of disseminated tuberculosis presenting as mesenteric and cerebral abscess in a HIV case without involving lung and lymph nodes. Bone marrow smears and fine needle aspiration cytology (FNAC from mesenteric lesion were positive for acid fast bacilli (AFB and the diagnosis of tuberculosis was confirmed by positive polymerase chain reaction (PCR.

    Full Text Available Mesenteric venous thrombosis is a rare cause of intestinal ischemia which is potentially life-threatening because it can lead to intestinal infarction. Mesenteric venous thrombosis rarely develops after abdominal surgery and is usually associated with coagulation disorders. Associated symptoms are generally subtle or nonspecific, often resulting in delayed diagnosis. A 68-year-old woman underwent laparoscopic exploration for small bowel obstruction, secondary to adhesions. During the procedure, an intestinal perforation was identified and repaired. Postoperatively, the abdominal pain persisted and repeat exploration was undertaken. At repeat exploration, a perforation was identified in the small bowel with a surrounding abscess. After the second operation, the abdominal pain improved but anorexia persisted. Contrast enhanced abdominal computed tomography was performed which revealed superior mesenteric venous thrombosis. Anticoagulation therapy with heparin was started immediately and the thrombus resolved over the next 6 days. Although rare, this complication must be considered in patients after abdominal surgery with unexplained abdominal symptoms.

    Full Text Available Mesenteric cysts are a rare phenomenon and can be encountered in different regions of the mesentery or in the retroperitoneal region. They are usually asymptomatic but may lead to a variety of symptoms depending on their site. We report a case of a mesenteric cyst presenting as a femoral hernia, which is, to our knowledge, the second case found in the literature. Forty-eight years old female patient presented with a history of pain and swelling in her left inguinal region for six months. Although femoral hernias are rare conditions, mesenteric cysts can protrude inside the femoral canal. In a case of clinical suspicion of such a condition, appropriate imaging should be performed.

    2015-01-01

    This article presents a narrative review of cystic lesions around the hip and primarily consists of 5 sections: Radiological examination, prevalence, pathogenesis, symptoms, and treatment. Cystic lesions around the hip are usually asymptomatic but may be observed incidentally on imaging examinations, such as computed tomography and magnetic resonance imaging. Some cysts may enlarge because of various pathological factors, such as trauma, osteoarthritis, rheumatoid arthritis, or total hip arthroplasty (THA), and may become symptomatic because of compression of surrounding structures, including the femoral, obturator, or sciatic nerves, external iliac or common femoral artery, femoral or external iliac vein, sigmoid colon, cecum, small bowel, ureters, and bladder. Treatment for symptomatic cystic lesions around the hip joint includes rest, nonsteroidal anti-inflammatory drug administration, needle aspiration, and surgical excision. Furthermore, when these cysts are associated with osteoarthritis, rheumatoid arthritis, and THA, primary or revision THA surgery will be necessary concurrent with cyst excision. Knowledge of the characteristic clinical appearance of cystic masses around the hip will be useful for determining specific diagnoses and treatments. PMID:26495246

    Cystic fibrosis (CF) is a hereditary metabolic disorder with clinical symptoms of abnormal mucus production. This blocks the airways, gives pancreatic insufficiency, and increases sweat electrolytes. The progressive respiratory disease often leads to respiratory insufficiency and cor pulmonale. The aim of the present investigation was to examine the facial morphology in children with cystic fibrosis. The sample comprised 11 children with cystic fibrosis, who were divided in two groups, one with gastrointestinal disorders and the other with predominantly respiratory insufficiency. Eleven healthy children with normal occlusions were selected as controls. Lateral skull radiographs obtained in natural head posture were digitized, and linear and angular variables for the different groups calculated and compared statistically. The cystic fibrosis group showed open bite, decreased posterior facial height, increased mandibular and craniocervical inclination. Additionally, within the CF-group, the children with respiratory insufficiency differed more from the controls than the children with gastrointestinal disorders. Despite the small number of subjects, the facial morphology of the CF children showed a similar pattern to that of children with nasal respiratory obstruction due to enlarged adenoids or tonsils.

    The intestinal lymphatic system plays key roles in fluid transport, lipid absorption and immune function. Lymph flows directly from the small intestine via a series of lymphatic vessels and nodes that converge at the superior mesenteric lymph duct. Cannulation of the mesenteric lymph duct thus enables the collection of mesenteric lymph flowing from the intestine. Mesenteric lymph consists of a cellular fraction of immune cells (99% lymphocytes), aqueous fraction (fluid, peptides and proteins such as cytokines and gut hormones) and lipoprotein fraction (lipids, lipophilic molecules and apo-proteins). The mesenteric lymph duct cannulation model can therefore be used to measure the concentration and rate of transport of a range of factors from the intestine via the lymphatic system. Changes to these factors in response to different challenges (e.g., diets, antigens, drugs) and in disease (e.g., inflammatory bowel disease, HIV, diabetes) can also be determined. An area of expanding interest is the role of lymphatic transport in the absorption of orally administered lipophilic drugs and prodrugs that associate with intestinal lipid absorption pathways. Here we describe, in detail, a mesenteric lymph duct cannulated rat model which enables evaluation of the rate and extent of lipid and drug transport via the lymphatic system for several hours following intestinal delivery. The method is easily adaptable to the measurement of other parameters in lymph. We provide detailed descriptions of the difficulties that may be encountered when establishing this complex surgical method, as well as representative data from failed and successful experiments to provide instruction on how to confirm experimental success and interpret the data obtained.

    The optimal extent of mesenteric resection in colon cancer surgery is not known. We have previously shown an increased mortality associated with wider mesenteric resection in right hemicolectomy. This study compares the short- and long-term outcome in three variations of right hemicolectomy based on the position of the vascular ligature in the mesentery. In all, 2084 cases of cancer in the caecum or ascending colon were identified in the Swedish Colorectal Cancer Registry and categorized according to the position of the vascular ligature: central ligation of ileocolic vessels (ICVs) ± right colic vessels (n = 390), central ligation of ICVs + right branch of middle colic vessels (MCVs) (n = 1360) and central ligation of ICVs + central ligation of MCVs (n = 334). Neither 3-year overall survival, 3-year disease-free survival nor local recurrence rate differed between the groups (P = 0.604; P = 0.247; P = 0.237). There was still no difference after multivariate analysis adjusted for age, sex, American Society of Anesthesiologists classification, TNM stage and adjuvant therapy. An increased peri-operative mortality, however, was observed in extended mesenteric resections, increasing from 0.8% in non-extended to 3.6% in more extended resection, P = 0.025. The study showed no survival benefit by more extended mesenteric resection, indicating that there is no need to extend the mesenteric resection to involve the MCVs in cancer of the caecum or ascending colon. On the contrary, increased peri-operative mortality by more extensive mesenteric resection was noted suggesting that a more conservative approach may be favourable.
