目的：研究MRI对椎管内囊性神经鞘瘤的诊断价值及鉴别诊断。方法：回顾性分析经病理证实的MR表现为椎管内囊性神经鞘瘤10例，6名男性，4名女性，年龄范围37~62岁，平均年龄51.4岁。结果：MRI显示病变均位于髓外硬膜下，T1 WI表现为低信号，T2 WI表现为高信号，增强扫描显示为环状强化。结论：MRI是诊断椎管内囊性神经鞘瘤的重要手段，其MR及增强扫描表现比较典型，对外科手术计划有很大帮助。由于其典型的强化特点鉴别诊断并不复杂。

Objective:To study the value of MRI in diagnosing spinal cystic schwannoma. Methods:Reviewed the MR images of 10 patients(6 males and 4 females,age ranged from 37 to 62 years old,mean age 51. 4 years dd)with pathologically proven cystic schwannoma of the spine. All patients were treated surgically in our Institutions. Results:MR imaging of all patients showed well-delineated intradural and extramedullary( IDEM)lesion of low signal inten-sity on T1 weighted images(T1WI),high signal intensity on T2 weighted images(T2WI),and rim enhancement on contrast enhanced images. Conclusion:Accurate understanding of MRI features may help clinicians maKe preoperative diagnoses and assist in surgical planning. Differential diagnoses is uncomplicated because of its typical characteristic of enhancement.
