Abstract：
Intraneural ganglia are rare, benign cysts that form within the epineurium of the affected nerve. Patients present with features of compressive neuropathy, including numbness. We report a 74-year-old male patient with pain and numbness on his right thumb of 1-year duration. Magnetic resonance imaging revealed a cystic lesion with a possible scaphotrapezium-trapezoid joint connection. The articular branch was not identified during the surgery and decompression with excision of the cyst wall was done. A recurrence of the mass was noted 3 years later, but the patient was asymptomatic and no additional intervention was done. Decompression alone can relieve the symptoms of an intraneural ganglion, but excision of the articular branch may be essential in preventing its recurrence. Level of Evidence: Level V (Therapeutic).
摘要：
神经内神经节很少见，在受累神经外膜内形成的良性囊肿。患者表现出压迫性神经病的特征，包括麻木。我们报告了一名74岁的男性患者，其右手拇指疼痛和麻木持续1年。磁共振成像显示囊性病变，可能有肩梯形-梯形关节连接。手术期间未发现关节分支，并进行减压并切除囊壁。3年后发现肿块复发，但患者无症状,未进行额外干预.单纯减压术可以缓解神经内神经节的症状，但是切除关节分支可能对防止其复发至关重要。证据等级：V级（治疗）。
