Adamantiades-Behçet disease is a multisystemic disorder that classically presents with oral and genital ulcers and ocular involvement, with vascular involvement in up to 38% of cases. Aortic involvement is one of the most serious manifestations and is associated with high mortality rates, occurring in 1.5 to 2.7% of cases. We report a case of a saccular abdominal aorta aneurysm in a 49-year-old male patient with complicated Adamantiades-Behçet disease that was treated with endovascular repair.
