Intraneural ganglia are nonneoplastic cystic formations contained within the epineurium of peripheral nerves. The common peroneal nerve at the fibular neck is the most frequently affected site. Intraneural ganglia are not a frequent occurrence in the adult patients and are even rarer in children, with only 10 pediatric cases reported in the English language literature. We report on a new pediatric case of intraneural ganglion of common peroneal nerve and present a review of the English language literature on this topic in children.
A 10-year-old girl was admitted to our institution because of pain referred to posterior and anterior aspects of the right leg and right foot drop. The radiologic investigations showed a wide (20 cm long) intraneural ganglion cyst of the right common peroneal nerve. The patient underwent surgical treatment according to the Spinner technique.
Postoperative course was uneventful. A gradual improvement of motor and sensory functions was observed, starting from the third postoperative day, with a complete motor function restoration registered 26 months after surgery.
Intraneural ganglia of the common peroneal nerve should always be considered in the differential diagnosis of foot drop in pediatric age since because early diagnosis and adequate surgical treatment play a crucial role in the patient's motor and sensory outcomes.
神经内神经节是位于周围神经外膜内的非肿瘤性囊性结构。腓骨小头处的腓总神经是最常受累部位。神经内神经节在成年患者中并不常见，在儿童中更为罕见，英文文献中仅报道了10例儿科病例。我们报告一例新的小儿腓总神经神经内神经节病例，并对英文文献中关于儿童这一主题的内容进行综述。
一名10岁女孩因右下肢前后侧疼痛及右足下垂入住我院。影像学检查显示右侧腓总神经有一个较大（长20 cm）的神经内神经节囊肿。患者根据Spinner技术接受了手术治疗。
术后过程顺利。从术后第三天开始观察到运动和感觉功能逐渐改善，术后26个月运动功能完全恢复。
小儿年龄组足下垂的鉴别诊断中应始终考虑腓总神经神经内神经节，因为早期诊断和适当的手术治疗对患者的运动和感觉预后起着关键作用。
