椎管外神经根鞘膜瘤与腰骶神经节异位误诊分析

Misdiagnosis of extraspinal neurilemmoma and ectopic lumbo-sacral ganglia

目的提高对椎管外神经根鞘膜瘤与腰骶神经节异位的临床诊断水平。方法对误诊为腰椎间盘突出而行开放手术治疗的10例患者进行回顾性分析。结果术后确诊为腰椎间盘突出1例,神经鞘瘤3例,腰椎管(侧隐窝或神经根管)狭窄6例。10例均获随访,时间1～3年,患者腰腿痛症状均有不同程度缓解,其中6例完全缓解。结论椎管外神经根鞘瘤与腰骶神经节异位临床误诊率较高,术前仔细检查可减少误诊率,而手术探查也极为重要。

Objective To improve the clinical diagnosis extraspinal neurilemmoma and ectopic lumbo-sacral ganglia. Methods A retrospective analysis was made for 10 cases which were treated with open operation as lumbar disc herniation. Results Postoperative diagnosis was lumbar disc herniation in 1 case, extraspinal neurilemmoma in 3 cases, lumbar spinal stenosis in 6 cases. The 10 cases were all followed up for 1 - 3 year. The symptom of patients＇ lumbar-leg pain all relieved in some degree and 6 relieved completely. Conclusions The extraspinal neurilemmoma and ectopic lumbo-sacral ganglia have high rate of misdiagnosis, the examination before operation can reduce misdiagnosis, and operation is more important too.
