Abstract
Adventitial cystic disease (ACD) is rare, affecting mainly young men. The majority of ACD occurrs in the popliteal artery. We report a 73-year-old man with ACD of the femoral artery. The diagnosis was made with duplex ultrasound which showed the multiple cystic lesions around right femoral artery and computed tomography. We resected the femoral artery, together with the cysts. To our knowledge, this is the most elderly case of ACD to have been reported.
