Cubital tunnel syndrome refers to compression neuropathy caused by pressure on the ulnar nerve pathway around the elbow. A 63-year-old male patient visited the clinic complaining of decreased sensation and weakness in his left ring finger and little finger, stating that the symptoms first began 6 months prior. He had undergone surgery to remove a ganglion cyst from his left elbow joint about 5 years prior in Mongolia. Magnetic resonance imaging revealed a cystic mass located at the previous surgical site, which was compressing the ulnar nerve within the cubital tunnel. Ulnar nerve decompression and anterior transposition were performed, and the cystic mass was excised. Upon pathological examination, the mass was diagnosed as a ganglion cyst. The patient's symptoms including sensory dysfunction and weakness improved over the 1-year follow-up period. This report describes a rare case of ganglion cyst recurrence compressing the ulnar nerve in the cubital tunnel after previous ganglion cyst excision.
肘管综合征是指因肘部周围尺神经通路受压而引起的压迫性神经病变。一名63岁男性患者前来诊所就诊，主诉左手无名指和小指感觉减退及无力，称症状始于6个月前。他大约5年前在蒙古国接受过手术，切除左肘关节处的一个腱鞘囊肿。磁共振成像显示在先前手术部位有一个囊性肿物，压迫肘管内的尺神经。进行了尺神经减压和前移手术，并切除了囊性肿物。经病理检查，该肿物被诊断为腱鞘囊肿。在1年的随访期内，患者包括感觉功能障碍和无力在内的症状有所改善。本报告描述了一例罕见的腱鞘囊肿复发病例，在先前腱鞘囊肿切除术后压迫肘管内的尺神经。
