Abstract

A 56-year-old woman presented with bright-red blood from the rectum. Esophagogastroduodenoscopy revealed mild gastritis. Colonoscopy demonstrated diverticulosis without active bleeding, and in vitro tagged red blood cell scintigraphy was unremarkable. There was no further evidence of bleeding and the patient was discharged home. The patient returned with recurrent bright-red blood from the rectum. Although delayed scintigraphic images seldom demonstrate the site of bleeding, delayed images at 12 hours demonstrated active bleeding near the hepatic flexure in this patient. This was confirmed with selective mesenteric angiography, and was treated with coil embolization of the tertiary branches of the right middle colic artery.
