Behçet's disease consists of a systemic vasculitis that affects veins, arteries and capillaries, but predominantly small vessels. Veins and medium- and large-caliber arteries are rarely involved; however, arteries are less involved than veins. In this paper the authors present a case of popliteal artery aneurysm in a patient with decompensated Behçet's disease. We discuss clinical, radiological and surgical aspects of patients with this inflammatory systemic disease who present important peculiarities.
