A case of massive colonic hemorrhage in nontoxic, quiescent ulcerative colitis is described. The source of active colonic bleeding was primarily defined with selective superior mesenteric arteriography and was completely controlled with transcatheter vasopressin infusion. A subsequent elective segmental distal transverse and descending colectomy revealed chronic ulcerative colitis; localized marked inflammatory giant pseudopolyp formation near the splenic flexure was responsible for the bleeding.
