[Mesenteric panniculitis associated with acute pancreatitis: about a case]. / Panniculite mésentérique associée à une pancréatite aiguë: à propos d'une observation.

Mesenteric panniculitis is a nonspecific inflammation involving the mesentery. Its clinical presentation is variable depending on the stage of the disease. Clinical signs are usually pain but half of the patients remain asymptomatic. Palpable abdominal mass, weight loss, nausea and vomiting. There may be an inflammatory syndrome of variable intensity. Panniculitis is suspected based on scan showing hyperdense mesentery with adhesions to adjacent organs. Histologically there is adipocyte degeneration causing foreign body reaction and appear lymphoplasmacytic inflammatory lesions. We report a new case of mesenteric panniculitis associated with acute pancreatitis.
