title: Arterial dysplasia of the colonic arteries: a rare cause of hemoperitoneum.
abstract: A case is reported of hemoperitoneum in a 66-year-old man. Abdominal angiography showed alternate narrowed and dilated segments in all the colonic arteries. A total colectomy was performed. Pathologic examination of the arteries showed, in the media and intima, some lesions of dysplastic character, which leads to a diagnosis of arterial dysplasia.
