Abstract
Brucellosis is a multisystem zoonotic disease. Mycotic aneurysm due to Brucella is rare and has no clear management approach. Here, we present two cases of mycotic aortic aneurysm due to Brucella. The first patient was treated with surgical resection of a symptomatic infrarenal abdominal aortic aneurysm combined with lifelong doxycycline and rifampicin. The second patient improved with conservative treatment including a 6-month course of antibiotics and regular clinical and radiologic monitoring. Through these cases, we hope to draw attention to this serious adverse effect of Brucella and the importance of management of its local arterial complications, especially in endemic areas.
