我们报告一例 69 岁男性患者，其表现为右手疼痛、无力和笨拙。初步评估表明可能有肿瘤形成影响他的颈椎，幸运的是骨活检排除了这一可能性。随后的电诊断研究和磁共振成像证实了深部尺骨运动分支的病变。对盖恩管进行探查，发现并切除了涉及尺神经深部运动支的神经内神经节。尽管症状持续时间超过 14 个月，但患者几乎完全康复，几乎没有任何功能限制。这为神经内神经节切除和神经减压的功能益处提供了支持证据，即使在慢性肌肉萎缩的情况下也是如此。
We report a case of a 69-year-old male who presented with pain, weakness, and clumsiness of his right hand. Initial evaluation suggested possible neoplastic process affecting his cervical spine, which was fortunately ruled out by bone biopsy. Subsequent electrodiagnostic studies and magnetic resonance imaging confirmed a lesion of the deep ulnar motor branch. Exploration of Guyon's canal was performed, and an intraneural ganglion involving the deep motor branch of the ulnar nerve was found and excised. Despite more than 14months of symptomatic duration, the patient made a near-complete recovery with virtually no functional limitations. This provides supporting evidence for a functional benefit of intraneural ganglion excision and nerve decompression even in cases of chronic muscle atrophy.
