Aortocaval fistula: CT appearance with pathological correlation.

Atherosclerotic aneurysm of the abdominal aorta is a frequent finding in a general hospital patient population. Most complications such as rupture, thrombosis and superinfection are well known. We report on a patient with aortocaval fistulization. This rare complication was diagnosed on contrast enhanced computed tomography. Pathological correlation was obtained as attempted surgery was unsuccessful.
