Perforation and hemorrhage of a non-Meckelian ileal diverticulum: preoperative angiographic diagnosis.

A 54-year-old male with infective bacterial endocarditis experienced right lower quadrant pain and gastrointestinal hemorrhage. The clinical impression of hemorrhagic diverticulitis was supported by the preoperative angiographic findings of a collection of extravasated contrast material in the right lower quadrant of the abdomen originating from a branch of the ileocolic artery. Exploratory laparotomy and pathologic examination of the resected specimen confirmed an ileal diverticulum which had perforated and was the source of hemorrhage.
