A CASE OF DIFFUSE HEMANGIOMA IN THE RECTOSIGMOID COLON WHICH PRODUCED SEVERE ANEMIA

Abstract

We report a case of cavernous hemangioma in the rectosigmiod colon. A 16-year-old male was admitted to our hospital because of melena and severe anemia. Colonoscopic examination showed edematous mucosa, telangiectasia, and wavy vascularization in the rectosigmoid colon. CT scan and MRI examination revealed that the lesional wall was remarkably thickened. The inferior mesenteric arteriograms showed diffuse prolonged stainings in the arteries in the involved intestine. Based on these examination, he was diagnosed as having diffuse hemangioma in the rectosigmoid colon. The hemangioma in the large intestine is rare, and only 19 cases have been reported in our country, including the one presented here.
