Abstract

 

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.
