摘　　要：目的:分析评价髓外硬膜下肿瘤的MRI表现及影像学特征,提高诊断与鉴别诊断水平。方法:收集经MRI检查手术病理证实的髓外硬膜下肿瘤58例,对其MRI表现及影像学特征进行回顾性分析。结果:58例髓外硬膜下肿瘤中,神经鞘瘤24例,神经纤维瘤18例,脊膜瘤8例,脂肪瘤5例,畸胎瘤3例,各种不同肿瘤的MRI征象,都各有其特征性。结论:髓外硬膜下肿瘤MRI检查是首选方法、定位、定性诊断及鉴别诊断均有重要价值。Objective：To evaluate the MR signs of primary subdural extramedullary tumors so as to improve the level of diagnosis and differential diagnosis. Methods： MR signs of 58 cases with primary subdural extrameduUary tumos were studied retrospectively. All eases were verified by surgery and pathology. Results： Of 58 eases with primary subdural extramedullary tumors, schwannoma （n = 24）, neurofibroma （ n = 18）, meningioma （ n = g ）, lipoma （ n = 5）, teratoma （ n = 3）, all eases had specific MR features. Conclusion： MRI is the most valuable and first-selected methods for diagnosis primary subdural extramedullary tumors and the diagnosis of qualitation and localization have important valuable.
