Tuberculous aneurysms of the abdominal aorta.

Mycotic aneurysm secondary to tuberculous infection of the aorta is a rare and life-threatening disease. We report a single-center experience of three patients treated with a combination of surgical aortic replacement and prolonged antituberculosis therapy. The first case is a 34-year-old woman with a suprarenal abdominal aortic aneurysm, the second case is a 77-year-old man with an infrarenal abdominal aortic aneurysm and a right psoas abscess, the third case is a 37-year-old woman with an infrarenal abdominal aortic aneurysm. All patients had a favorable outcome with a mean follow-up of 6.2 years (range, 6 months-10 years). Early diagnosis and a combination of surgical intervention (aortic reconstruction and extensive excision of the infected field) and prolonged antituberculous drug therapy provide long-term survival without evidence of recurrence after tuberculous aortic involvement.
