中文摘要：

[目的]总结椎管内髓外肿瘤诊疗方法并分析其影响预后的相关因素。[方法]回顾性分析手术治疗168例椎管内髓外肿瘤患者，分析其影像学特点，并通过JOA评分评价临床疗效。评价患者病程、年龄、术前JOA评分与临床效果之间的关系。[结果]患者平均42岁（7—73岁），平均病程18．6个月（2—28个月）。肿瘤位于颈段者45例（28．7％），胸段者62例（39．5％），腰骶段者61例（38．9％），以神经鞘瘤和脊膜瘤为主，分别占53．6％、22．6％。随访时间为13—52个月，平均29．8个月，肿瘤完全切除160例（95．2％），部分切除8例（4．8％）。JOA评分：术前5—12分，平均7．6分，术后8—16分，平均13．8分，改善率为66．0％。依据Epstein标准：优150例，良10例，改善8例。患者病程、年龄与临床改善率呈负相关，相关系数分别为-0．353、-0．521，术前JOA评分与临床改善率呈正相关，相关系数为0．413。[结论]椎管内肿瘤临床疗效与病程、年龄、术前症状存在显著相关性。详细的病史采集、体检和影像学MRI检查是关键的诊疗手段。

英文摘要：

[ Objective ] To summarize the experiences in management of intraspinal -extramedulary tumors. [ Methods ] The clinical characteristic, imaging examination and clinical effects of 168 patients with intraspinal - extramedulary tumors ad- mitted to our department for surgical treatment in the last 10 years were retrospectively analyzed. [ Results] In this group, the intraspinal tumors included neurinoma in 96 cases （53.6%） , meningiomas in 38 cases （22. 6% ）, lipoma in 4cases （2.4%）, metastasis tumor in 8 cases （4. 7% ）, ganglioneuroma in 3cases （1.8%）, hemangioma in 5 cases （3.0%）, angiolipoma in 2 cases （1.2%） , arachnoid cyst in 1 case （0.6%） , epidermoid cyst in 8 cases （4.8%） , dermoid cyst in 4 cases （3.6%） , teratoma in 4 cases （2. 4% ） . According to the locations, 45 cases （28.7%） located at cervical region, 62 cases （39. 5% ） at thoracic region, 61 casess （38. 9% ） at lumbar and sacral region. All the patients in this group underwent operative treat- ment. 160 cases （ 92. 5% ） were totally resected, 8 cases （ 4. 8% ） were subtotally resected. Postoperatively, 143 cases 89. 9% ） were cured, the neurological symptoms were apparently improved in 8 cases （ 5% ） , and unchanged in 5 cases 3. 1% ） . Three cases recurred. One case was operated on again. No operative death occurred. [ Conclusion ] Early diagnosis and treatment of spinal tumor are important measures to improve prognosis. Detailed history - taking, careful examination and MRI imaging play a key role in the diagnosis and treatment of spinal tumors.
