Computed tomographic demonstration of intramural colonic air (pneumatosis coli) as a feature of severe ulcerative colitis

Fast rotational computed tomographic scanning techniques allow an accurate appreciation of the diameter of the colon, the presence of severe necrotizing mucosal change, and the detection of unsuspected intramural colonic air (pneumatosis coli) in cases of severe necrotizing ulcer ative colitis. © 1987 Springer-Verlag New York Inc.
