Peripheral neuropathies caused by ganglion cysts are rare, particularly in the lower extremities. The case of a 45-year-old man with a two-month history of foot drop and swelling in the region of the right fibular head is presented. Physical examination and electromyogram studies verified a peroneal nerve palsy. Magnetic resonance imaging revealed a lobulated, multilocular, cystic-appearing mass extending around the fibular neck. Surgical decompression of the nerve with removal of the mass and careful articular branch ligation was performed. Surgical pathology reports confirmed the diagnosis of a ganglion cyst. The patient regained full function within four months of the decompression. Pertinent findings on physical examination are discussed, as well as electromyogram and magnetic resonance imaging results. If symptoms persist, early surgical decompression (between the third and fourth months) is recommended.
由腱鞘囊肿引起的周围神经病变很少见，尤其是在下肢。本文介绍了一名45岁男性患者，其右腓骨头区域有两个月的足下垂和肿胀病史。体格检查和肌电图检查证实为腓总神经麻痹。磁共振成像显示一个分叶状、多房性、呈囊性的肿块围绕腓骨颈延伸。对神经进行了手术减压，切除了肿块并仔细结扎了关节分支。手术病理报告证实为腱鞘囊肿。患者在减压后四个月内恢复了全部功能。讨论了体格检查的相关发现以及肌电图和磁共振成像结果。如果症状持续存在，建议早期（在第三个月至第四个月之间）进行手术减压。
