title: A complicated case of aortoduodenal fistula.
abstract: Aortoduodenal fistula may occur primarily as a complication of abdominal aortic aneurysm or secondarily after reconstructive surgery of the abdominal aorta. The clinical presentation may be occult, with the classic triad of mass, pain, and bleeding inapparent or overshadowed by signs of infection. A high index of clinical suspicion combined with radiographic and endoscopic examinations will establish the diagnosis.
