Abstract

A 68-year-old man was admitted to our hospital, complaining of general malaise with severe anemia. No bleeding site could not be detected by barium enema X-ray examination and upper GI endoscopy. A flat protrusion with redness was observed in the ascending colon by colonoscopy. Spurting bleeding occurred from this lesion just after biopsy specimens were taken. Selective angiography revealed proliferation of capillaries and early venous return. Therefore, arteriovenous malformation of the ascending colon was diagnosed. Recently, reports of arteriovenous malformation of the ascending colon increase. Therefore, it is suggested that flat protrusion seen in the ascending colon could be arteriovenous malformation.
