  • Abstract
  • Look Inside

 A 55-year-old female was admitted to our hospital with complaints of intermittent gastrointestinal hemorrhage. The source of bleeding could not be detected by endoscopic and x-ray examinations of the upper GI series and barium enema study. In a colonoscopic examination at our hospital, a cluster of dilated tortuous vessels at the transverse colon was seen. Arteriography of the superior mesentery revealed dilated tortuous arteries and early venous return at the mid-transverse colon. Arteriovenous malformation(AVM)was finally diagnosed.

 Histological examination of the resected specimen demonstrated dilated vessels in the mucosal and submucosal layer. Colonofiberscopy and arteriography are considered to be important diagnostic procedures for AVM of the colon.
