Nodular fasciitis, a benign soft tissue tumor, occurs most frequently in the forearm and is generally divided into subcutaneous, intramuscular, and fascial types. Intraneural nodular fasciitis has been reported in only 5 patients previously. We present the case of a 79-year-old woman with nodular fasciitis within the median nerve at the proximal forearm. Carpal tunnel syndrome was suspected at the initial visit, but high median nerve palsy and a mass at the proximal forearm were found a few months later. Subtotal resection of the tumor within the median nerve was performed and histological diagnosis indicated nodular fasciitis. There was no evidence of recurrence at follow-up 1 year and 3 months after surgery. Motor weakness had resolved but sensation was compromised.
结节性筋膜炎是一种良性软组织肿瘤，最常发生于前臂，通常分为皮下型、肌内型和筋膜型。此前仅有5例关于神经内结节性筋膜炎的报道。我们报告了1例79岁女性患者，其在前臂近端正中神经内患有结节性筋膜炎。初诊时怀疑为腕管综合征，但数月后发现正中神经高位麻痹及前臂近端有一肿块。对正中神经内的肿瘤进行了次全切除，组织学诊断为结节性筋膜炎。术后1年零3个月的随访中未发现复发迹象。运动无力已缓解，但感觉仍有受损。
