Anomalous muscles are rarely seen in the popliteal region of the lower limb. Some of them are harmless and go unnoticed and some create problems such as neuropathies. We report a novel case of an unusual additional muscle in this region. The additional muscle was closely associated with the short head of the biceps femoris muscle. It took its origin from the lower part of the lateral supracondylar line and the adjoining popliteal surface of the femur. The muscle was 10 cm in length, 1 cm in breadth and was fleshy throughout. It was oriented parallel to the medial side of the tendon of biceps femoris. It was inserted to the posterior aspect of the head of the fibula, medial to the insertion of the biceps femoris. The additional muscle derived its nerve supply from the sciatic nerve. The common peroneal nerve was closely related to the medial border of the additional muscle.
下肢腘窝区域很少见到异常肌肉。有些是无害的，不被注意到，有些则会造成神经病变等问题。我们报告一个该区域不常见的附加肌肉的新病例。该附加肌肉与股二头肌短头紧密相关。它起自外上髁线的下部和股骨的毗邻的腘面。该肌肉长 10 厘米，宽 1 厘米，整个肌肉都是肉质的。它与股二头肌腱的内侧平行排列。它插入到腓骨头的后侧面，位于股二头肌插入点的内侧。该附加肌肉的神经供应来自坐骨神经。腓总神经与附加肌肉的内侧边界密切相关。
