摘　　要：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，T1WI表现为低信号，T2WI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.
