title: Angiographic demonstration of bleeding in a unusually located Meckel's diverticulum simulating colonic bleeding.
abstract: A case is reported in which bleeding from a Meckel's diverticulum was mistakenly localized to the hepatic flexure of the colon on superior mesenteric angiography. An unusually long and mobile mesentery, allowing the bleeding Meckel's diverticulum to be positioned high in the right upper quadrant, led to this misdiagnosis. The case illustrates several fundamental principles about the technique and interpretation of mesenteric angiograms.
