A 23-year-old previously healthy male was referred to the clinical neurophysiology unit due to a relatively fast-onset paralysis of muscles of the anterior right leg. Electroneuromyography (ENMG) revealed a total denervation of the muscles innervated by the deep peroneal nerve, diminished sensory response of the superficial peroneal nerve, and partial denervation of the peroneus longus muscle. Ultrasound and magnetic resonance imaging (MRI) revealed a large fluid collection inside the common peroneal nerve, primarily suspected to be an intraneural ganglion cyst. The cyst was surgically excised, and the function of the muscles innervated by the peroneal nerve was recovering at the control ENMG 6 months later. We describe a case of a large intraneural ganglion cyst of the peroneal nerve in an otherwise healthy young male, diagnosis by ENMG, ultrasound, and MRI, as well as subsequent operative treatment. This report demonstrates the utility of nerve ultrasound in differentiating between different causes of peroneal nerve dysfunction.
一名23岁既往健康的男性因右前腿部肌肉相对快速出现的麻痹被转诊至临床神经生理学科室。肌电图(ENMG)显示腓深神经支配的肌肉完全失神经支配,腓浅神经感觉反应减弱,以及腓骨长肌部分失神经支配。超声和磁共振成像(MRI)显示腓总神经内有大量液体积聚,主要怀疑为神经内腱鞘囊肿。该囊肿通过手术切除,6个月后复查肌电图时,腓神经支配的肌肉功能正在恢复。我们描述了一例在其他方面健康的年轻男性中发生的腓总神经巨大神经内腱鞘囊肿病例,通过肌电图、超声和MRI进行诊断,以及随后的手术治疗。本报告展示了神经超声在鉴别腓总神经功能障碍不同病因方面的作用。
