1/19. Retractile mesenteritis presenting as fever of unknown origin and autoimmune haemolytic anaemia.Retractile mesenteritis is an extremely rare disease characterised by a non-specific inflammatory and fibrotic process of the mesenteric adipose tissue, which is usually accompanied by pain and a variety of other abdominal symptoms. We describe here the case of a patient with retractile mesenteritis presenting with prolonged high-grade fever and autoimmune haemolytic anaemia without abdominal symptoms. The patient's illness was complicated by chylous ascites. diagnosis was suspected by computed tomography and confirmed histologically following exploratory laparotomy. The patient was treated with prednisone and azathioprine, and he had a rapid improvement in anaemia and fever relief, but no substantial change in the mesenteric lesions. Our case adds autoimmune haemolytic anaemia to the wide spectrum of manifestations of retractile mesenteritis and implies the possible involvement of immune mechanisms in the pathogenesis of the disease.- - - - - - - - - - ranking = 1keywords = adipose (Clic here for more details about this article) |
2/19. Intraabdominal panniculitis. Report of three cases and review of the literature.Intraabdominal panniculitis is a rare, benign idiopathic disorder of the mesentery. patients usually present with abdominal pain and a palpable mass. The cross-sectional imaging findings are characteristic and consist of a fibrofatty central mesenteric mass lesion encapsulating the mesenteric vessels with displacement of the bowel loops, that can suggest the diagnosis. Imaging is also important to establish a definitive diagnosis by an image-guided percutaneous biopsy, assess extent of the disease for selection of appropriate therapy, exclude associated abnormalities namely malignancies, and for follow-up.- - - - - - - - - - ranking = 0.0040661225439849keywords = fat (Clic here for more details about this article) |
3/19. Aggressive multiple myeloma presenting as mesenteric panniculitis.Mesenteric panniculitis is a rare disease of the bowel mesentery, characterized by tumor-like infiltration by chronic inflammatory cells, fat necrosis, and fibrosis. Reported cases cited clinical presentation ranging from abdominal pain to fever of unknown origin, the majority of which were idiopathic and associated with a benign prognosis. We report the case of a 43-yr-old male who presented with malaise, weight loss, microcytic anemia, and a high erythrocyte sedimentation rate. Radiographic and histological investigations revealed typical features of mesenteric panniculitis. Initial treatment with high-dose oral prednisolone led to rapid and complete resolution of symptomatology, radiographic, and laboratory anomalies. Within 6 months, the patient presented again with anemia, renal failure, and hypercalcemia. A diagnosis of IgA kappa chain myeloma was made. Despite chemotherapy and restoration of normocalcemia, he died from refractory pulmonary edema. This is the first report of a hematological malignancy initially presenting with features of mesenteric panniculitis culminating in an aggressive course and a fatal outcome.- - - - - - - - - - ranking = 0.0081322450879698keywords = fat (Clic here for more details about this article) |
4/19. Mesenteric panniculitis of the colon with obstruction of the inferior mesenteric vein: report of a case.Mesenteric panniculitis is a rare disease characterized by nonspecific inflammation of the fat tissue of the mesentery. We present an extremely rare case of mesenteric panniculitis of the sigmoid colon, complicated by occlusion of the inferior mesenteric vein. A 75-year-old male presented with a one-month history of abdominal distention and abdominal mass without pain. physical examination revealed a firm mass in the lower abdomen. barium enema study demonstrated rugged mucosa and a serrated contour in the rectosigmoid colon. Computed tomography showed that the mass arose from the mesentery, which surrounded the mesenteric vessels. The density of the mass was slightly higher than that of fatty tissue. Based on these radiologic findings, the patient was diagnosed as having mesenteric panniculitis of the rectosigmoid colon. colonoscopy showed narrowing with edematous mucosa in the rectosigmoid colon, whereas marked dilated vessels were noted in the proximal portion of the sigmoid colon. angiography showed occlusion of the inferior mesenteric vein, with venous flow returning via a collateral vein. The patient was observed without medication because his condition was satisfactory. His symptoms subsequently disappeared during a period of several weeks. The mass in the lower abdomen gradually diminished in size, disappearing three months later. Computed tomography and barium enema showed improvement of the lesion. The favorable outcome of the present case was probably because of formation of a collateral vein. The present case suggests that aggressive therapy for mesenteric panniculitis should be avoided, because the outcome of this disorder is good, even when there is obstruction of vessels.- - - - - - - - - - ranking = 0.0081322450879698keywords = fat (Clic here for more details about this article) |
5/19. Mesenteric panniculitis associated with abdominal tuberculous lymphadenitis: a case report and review of the literature.Mesenteric panniculitis is a rare disease characterized by chronic non-specific inflammation of the mesenteric adipose tissue. The specific aetiology of the disease is previously unknown. A case diagnosed as mesenteric panniculitis is presented. The cause was biopsy-proved abdominal tuberculous lymphadenitis. To our knowledge, mesenteric panniculitis associated with tuberculosis infection has not been reported previously in the literature. Thus, we would like to present the first case and describe CT features of the disease.- - - - - - - - - - ranking = 1keywords = adipose (Clic here for more details about this article) |

7/19. MR findings in a rare case of sclerosing mesenteritis of the mesocolon.Sclerosing mesenteritis is a rare, usually benign disorder of the mesentery. Depending on the predominant tissue component (inflammation, fat, or fibrosis), it is known as mesenteric panniculitis or retractile mesenteritis. We present a rare case of retractile mesenteritis of the mesocolon as a cause of severe abdominal pain. US, CT, and MRI were the imaging modalities used. We emphasize the MR finding of a fibrous capsula in retractile mesenteritis, as this is to our knowledge the first study to describe this entity. This finding may be valuable for establishing a diagnosis of sclerosing mesenteritis, as well as for differentiating this disease from other mesenteric diseases.- - - - - - - - - - ranking = 0.0040661225439849keywords = fat (Clic here for more details about this article) |
8/19. Sclerosing mesenteritis.Sclerosing mesenteritis is a rare benign process involving mesenteric fat that has non-specific histology and imaging characteristics, which are critical to the diagnosis. It has two different pathological variants: mesenteric panniculitis (acute or subacute) and retractile mesenteritis (chronic). This case study illustrates the radiological findings of sclerosing mesenteritis, describes certain signs that suggest the diagnosis and reviews recent published literature.- - - - - - - - - - ranking = 0.0040661225439849keywords = fat (Clic here for more details about this article) |
9/19. Mesenteric liposarcoma or lipodystrophy: an elusive diagnosis.Mass lesions of the mesentery may be fortuitously encountered on computerized tomographic (CT) scans, posing a diagnostic challenge. Despite CT, magnetic resonance (MR) imaging and a surgical biopsy, a patient with mesenteric lipodystrophy was misdiagnosed as having a low-grade mesenteric liposarcoma. Spontaneous regression of the mass on control CT scan and review of the pathological material prompted us to reconsider the diagnosis of malignancy. Because a wide variety of tumors and pseudotumors produce alterations in the density and volume of mesenteric fat on CT scan, a surgical biopsy is usually necessary to obtain a tissue-specific diagnosis, but even then pathological findings may be equivocal. As final resort the natural evolution assessed by radiological follow-up can be of help in determining the nature of the disease.- - - - - - - - - - ranking = 0.0040661225439849keywords = fat (Clic here for more details about this article) |
10/19. CT and MR features of sclerosing mesenteritis mimicking a mesenteric metastasis from the carcinoid tumor.Sclerosing mesenteritis is a rare and benign inflammatory entity characterized by fibrofatty thickening of the mesentery. To our knowledge, there are only a few reports on the features of sclerosing mesenteritis on magnetic resonance (MR) imaging and computed tomography (CT). In this present case, MR imaging demonstrated tissue characterization of fibrosis, and partial maximum intensity projection (MIP) and three-dimensional angiography images obtained using multislice CT clearly revealed the extent of the tumor and the vascular appearance affected by the mass. However, a mesenteric metastasis from the carcinoid tumor may show such imaging features. Therefore, when encountering such a case, we suggest that a tentative diagnosis of sclerosing mesenteritis be made, followed by a biopsy for intraoperative histopathologic analysis to avoid aggressive surgery.- - - - - - - - - - ranking = 0.0040661225439849keywords = fat (Clic here for more details about this article) |
