Combined capillary hemangioma and angiodysplasia of the ileum: an unusual cause of obscure gastrointestinal bleeding with preoperative localization by double-balloon endoscopy.

Vascular lesions in the small bowel with bleeding complications are usually difficult to diagnose and localize preoperatively. With the increased use of either capsule endoscopy or enteroscopy, there have been more reports of preoperative diagnosis from such lesions. The authors report a rare case of obscure gastrointestinal bleeding from a combined hemangioma and angiodysplasia identified by double-balloon enteroscopy. To the authors' knowledge, this is the first report of such combined lesions.
