A 16-year-old high school boy experienced intermittent claudication of his left lower limb during boxing training. Physical examination revealed a cold left foot and diminished pulse. A 64-row multi-slice CT (MSCT) demonstrated lateral shift and severe stenosis of the left popliteal artery due to malposition of the medial head of the gastrocnemius muscle. A diagnosis of popliteal artery entrapment syndrome (Delaney typeII) was established and a surgical correction was planned. During surgery, since the artery was found to be compressed but not occluded, we simply released the popliteal artery by division of the medial head of the gastrocnemius and abnormal flips of muscle. The postoperative ankle brachial pressure index rose from "not measurable" to 1.22. MSCT was useful to characterize this anomaly by expressing the precise anatomical relation of muscle, bone and artery, which was a good guide for an appropriate surgical intervention.
