We present a case of a 19-year-old male patient complaining of right leg pain, which appeared after exercise and abated with rest. Computed tomography (CT) and magnetic resonance angiography (MRA) showed occlusion of right popliteal artery. Volume rendering CT image showed not only occlusion of right popliteal artery but also abnormal course of the medial head of the gastrocnemius muscle (MHG). CT and MR images of right popliteal fossa showed the abnormal anatomy that MHG coursed between popliteal artery with thrombus and popliteal vein. Popliteal artery entrapment syndrome was diagnosed non-invasively by multidetector CT and MRI. Sectional radiological and three-dimensional images are useful for not only depiction of the arterial changes but also identification of the abnormal anatomic structures responsible for the entrapment.
我们报告一例19岁男性患者，主诉右腿疼痛，该疼痛在运动后出现，休息后缓解。计算机断层扫描（CT）和磁共振血管造影（MRA）显示右侧腘动脉闭塞。容积再现CT图像不仅显示右侧腘动脉闭塞，还显示腓肠肌内侧头（MHG）走行异常。右侧腘窝的CT和MR图像显示了异常解剖结构，即MHG在有血栓的腘动脉和腘静脉之间走行。通过多排CT和MRI无创诊断为腘动脉压迫综合征。断层放射图像和三维图像不仅有助于描绘动脉变化，还有助于识别导致压迫的异常解剖结构。
