| Mesenteric lipodystrophy (ML) is a rare condition characterized by a nonspecific inflammatory process that involves the root of the mesentery in a lipoma-like lesion. Presenting features of ML include abdominal pain, weight loss, nausea, vomiting, diarrhea, and constipation. This case illustrates that ML should be included in the differential diagnosis of patients with fever of unknown origin and mesenteric calcifications. ( info) |
2/43. Multiple nodular metastases in mesenteric panniculitis by uterine papillary serous adenocarcinoma (UPSC): CT appearance of a case. Intra-abdominal panniculitis is a thickening of the mesentery of the small/large intestine due to infiltration of lipid-laden macrophages associated with a variable amount of fibrosis. This condition is rarely associated with malignant neoplasms. We report the computed tomography (CT) findings of a patient treated for uterine papillary serous adenocarcinoma (UPSC). She had mesenteric panniculitis where metastatic tumor nodules implanted. This was the only intraperitoneal recurrence. To our knowledge, no such finding has been reported in the gynecologic and radiologic literature to date. On CT images, the differential diagnosis is with cystic dilatations of mesenteric lymph vessels. ( info) |
3/43. Mesenteric panniculitis: sonographic findings. BACKGROUND: Mesenteric panniculitis (MP) is a relatively rare disease, and sonographic (US) and color Doppler findings have been infrequently reported. methods: We reviewed the clinical data and US and Doppler results of three cases of MP to determine the role and limitations of these techniques. RESULTS: The sole presenting clinical sign was a soft mass. On US the lesion was imaged as a poorly margined echogenic mass with hypoechoic areas. color Doppler US visualized the nondeviated mesenteric vessels within the mass, which enabled us to perform a safe guided biopsy. CONCLUSIONS: US is useful as an initial diagnostic tool, but its results must be interpreted carefully. color Doppler US is very useful in demonstrating fine vessels and helps in performing a safe needle biopsy.

4/43. 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.

5/43. 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.

| 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. ( info) |

8/43. 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. ( info) |
9/43. Mesenteric panniculitis presenting with autoimmune haemolytic anaemia. Mesenteric panniculitis is a rare idiopathic inflammatory disorder that can lead to sclerosis. We describe a patient with mesenteric panniculitis presenting with abdominal symptoms and autoimmune haemolytic anaemia. The symptoms remitted after splenectomy and gradual steroid taper. This may suggest an autoimmune component in the aetiology of mesenteric panniculitis. ( info) |
10/43. 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. ( info) |
