Popliteal artery entrapment syndrome: accurate morphological diagnosis utilizing MRI.

A case of bilateral popliteal artery entrapment syndrome was accurately diagnosed utilizing magnetic resonance imaging (MRI) in a 34-year-old male with intermittent claudication. The abnormal structure was clearly visualized in relation to the popliteal artery in T1-weighted sagittal and axial sections of MRI. The type of entrapment was determined by this method prior to surgery. Intermittent claudication disappeared after surgical repair. Our experience emphasizes that MRI facilitates the accurate morphological diagnosis of popliteal artery entrapment syndrome.
