Tuberculous aortitis presenting with an aortoduodenal fistula: a case report.

An elderly man with tuberculous aortitis presented with massive gastrointestinal bleeding resulting from an aortoduodenal fistula. Aortic resection was successful, and he has done well over a 12 year period. The organism was recovered from the aorta and also seen on section of the neighboring lymph nodes. Although tuberculous aortitis is rare, it should be considered in a patient with prior history of tuberculosis who has developed evidence of aortic disease, aneurysm, or massive gastrointestinal bleeding.
