We report a case of synovial cyst that induced the compression of the peroneal nerve. The patient presented with foot drop and impossibility to stand on his right heel associated with numbness of anterolateral surfaces of the right shin and the dorsal surface of the foot within a 1-month period. Based on the clinical examination and electroneuromyography data, the compression of nerve by soft elastic mass was confirmed. We treated the patient by total microsurgical excision of the soft elastic mass adherent to the right peroneal nerve at the top third of the patient's shin. Histological study revealed the cyst of synovial membrane. During the postoperative period, a force in extensors of the right foot was restored. On the seventh day, the patient began to step on his right heel, while the zone of tenderness and temperature hypoesthesia in the area of the peroneal nerve innervation remained.
我们报告一例滑膜囊肿导致腓总神经受压的病例。患者在 1 个月内出现足下垂和无法用右脚跟站立，同时伴有右小腿前外侧和足背的麻木。根据临床检查和神经电图数据，证实了神经被软弹性肿块压迫。我们通过在患者小腿中上 1/3 处对附着于右侧腓总神经的软弹性肿块进行全显微镜下切除来治疗该患者。组织学研究显示为滑膜囊肿。术后，右脚伸肌的力量得到恢复。术后第 7 天，患者开始用右脚后跟站立，而腓总神经支配区域的压痛和温度感觉减退仍存在。
