CT features of mesenteric panniculitis.

Mesenteric panniculitis (MP) is an inflammatory process of the mesenteric fat associated with a variable amount of fibrosis. We present the CT findings in four patients with MP. In three patients CT showed a fatty mass in the root of the mesentery and surrounding the mesenteric vessels without distorting them. The fourth patient presented an unusual form of MP with radiologically visible calcifications. Diagnosis was suggested preoperatively in two cases.
