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 V (Therapeutic).
神经内腱鞘囊肿是一种罕见的良性囊肿，形成于受累神经的神经外膜内。患者表现为压迫性神经病的特征，包括麻木。我们报告了一例 74 岁男性患者，其右侧拇指疼痛和麻木持续 1 年。磁共振成像显示一个囊性病变，可能与舟月关节相连。术中未发现关节支，行囊肿壁切除减压。3 年后发现肿块复发，但患者无症状，未行进一步干预。单纯减压可缓解神经内腱鞘囊肿的症状，但切除关节支可能对预防其复发至关重要。 五级（治疗）。
