Peroneal intraneural ganglion cysts (IGCs) are nonneoplastic lesions. They are responsible for a small number of footdrop cases, which occur after additional nerve damage. The earliest patient symptom related to IGCs is knee pain.
A 17-year-old boy developed pain in the left knee, which progressively worsened over 14 months. He did not seek any medical assistance during this time. The patient subsequently was involved in a bicycle accident, and 3 months later he was unable to raise his left foot and was referred to our clinic for footdrop. Surgery was performed, but the weakness persisted. We could not detect any functional reinnervation on electromyography 12 months after surgery.
The most important factors in determining the prognosis of IGCs are the extent of the nerve trauma and the early diagnosis and treatment of the IGC. Detection of almost complete functional denervation on electromyography may indicate that it is too late for surgery.
腓总神经内神经节囊肿（IGC）是非肿瘤性病变。它们是少数足下垂病例的病因，这些病例发生在额外的神经损伤之后。与IGC相关的最早患者症状是膝关节疼痛。
一名17岁男孩出现左膝疼痛，在14个月内逐渐加重。在此期间他未寻求任何医疗帮助。该患者随后遭遇自行车事故，3个月后他无法抬起左脚，并因足下垂被转诊至我们诊所。进行了手术，但无力症状持续存在。术后12个月，我们在肌电图检查中未检测到任何功能性再支配。
决定IGC预后的最重要因素是神经创伤的程度以及IGC的早期诊断和治疗。肌电图检查发现几乎完全功能性失神经支配可能表明手术为时已晚。
