Adventitial cystic disease is a rare non-atherosclerotic vascular disease. We report a 36-year-old man with right intermittent claudication by adventitial cystic disease. computed tomography (CT) and magnetic resonance imaging (MRI) revealed an ovoid cystic mass compressing the right popliteal artery and causing severe stenosis of the lumen. Percutaneous aspiration was performed, which improved his symptoms. However, he complained of identical intermittent claudication two weeks later. Radiographic findings revealed that the cystic lesion had progressed rapidly. The cystic lesion was resected and the affected arterial segment was interposed. We consider that conventional surgical intervention remains the favored treatment option in the management of adventitial cystic disease.
