Un anévrysme de l'aorte abdominale révélant une maladie de Behçet

Behçet's disease is a vasculitis of unknown origin. Vascular lesions predominantly affect veins. Arterial involvement is rare but usually associated with poor prognosis. Aortic syndromes are usually aneurysmal and occasionally reveal Behçet's disease. We report the case of a 46-year-old man whose Behçet's disease was revealed by a sub-renal abdominal aortic aneurysm in pre-rupture state. The diagnosis of this disease was retained based on clinical, biological and radiological criteria. The surgical procedure consisted in the resection of the aneurysmal sac and the interposition of a prosthetic PTFE tube.
