We report a rare case of cystic adventitial disease of the popliteal artery causing intermittent claudication. About 2 months previously, a 21-year-old man had sudden intermittent claudication in the left leg. The left-sided ankle brachial pressure index（ABI）at rest was 0.66. Computed tomography revealed that the arterial occlusion was segmentally caused by cystic lesions. A cystic adventitial lesion of the popliteal artery, measuring 9cm in diameter, was surgically removed and reconstruction was performed with a saphenous vein graft. Postoperatively the left ABI improved to 1.01, and his symptoms disappeared. The histopathological diagnosis was cystic adventitial disease and the cysts were in the adventitia. The postoperative course was uneventful and he has been without recurrence for 14 months.
