Chronic mesenteric ischemia masquerading as cancer.

Mesenteric vascular insufficiency should be suspected in patients with a history of abdominal pain, marked weight loss and significant atherosclerosis. Selective mesenteric angiography is essential and should be used early in the work-up studies of such patients. To ensure clinical correlation, there should be significant occlusion demonstrated in two of the three major mesenteric arteries. Four patients studied extensively for an intra-abdominal neoplasm had occlusive disease of the mesenteric artery demonstrated by arteriography. Elective surgical revascularization of the intestine successfully corrected the problem.
