Abstract: The authors encountered 2 rare cases of adventitial cystic disease of the popliteal artery. Case 1 was a 51-year-old woman with dull pain in the lower limbs during walking. Case 2 was a 34-year-old man with numbness in the lower limbs on bending his knees. In both cases, angiography showed crescent stenosis, and computed tomography (CT) showed cyst-like lesions about the artery. Magnetic resonance imaging (MRI) indicated the lesions to have high density at T 2 imaging. With a diagnosis of adventitial cystic disease, cystectomy was conducted with satisfactory results. Adventitial cystic disease is rare and only 43 cases have so far been reported in this country. All of these were reviewed to clarify the characteristics of this disease. Its clinical symptoms often resemble those of arteriosclerosis obliterans (ASO) as intermittent claudication, but it differs from ASO in that it is usually achieved cure by cystectomy alone and seldomly required bypass operation. In the case of intermittent claudication in young patients, adventitial cystic disease should be diferrentiated from ASO.
