Ruptured tuberculous false aneurysm of the abdominal aorta: a case report.

Tuberculous false aneurysm of the aorta is rare and has an unpredictable complication of aneurysm rupture. We report a case of a 32-year old woman who was referred to the Department of Vascular Surgery, Avicenne Hospital for severe abdominal pain. Chest x-ray revealed miliary tuberculosis. Contrast enhanced computed tomography (CT) scan showed a false aortic aneurysm involving the juxtarenal aorta. Antituberculous treatment was started because of high presumption of tuberculosis. Five days later, the patient presented with symptoms of aneurysm rupture. She underwent an emergency a surgical resection of the aneurysm with repair of the aortic wall defect by a Dacron Silver patch. The histopathologic examination of the aortic wall showed features of tuberculosis.
