Computed Tomography in Crohn Disease

Abstract

Twelve patients with Crohn disease were studied by computed tomography. Characteristic findings of small intestinal involvement include symmetrical bowel wall thickening, a "double halo" appearance on cross section of the diseased bowel segment, and an associated mesenteric fat mass. Computed tomography provided crucial diagnostic information in the management of some of the intestinal and extraintestinal complications of the disease.
