"脑膜瘤"MRI误诊分析

目的　研究MRI在脑膜瘤诊断实践中的差距。方法　 15 2例经MR扫描初诊为脑膜瘤的病例与手术、病理相对照 ,从中遴选出诊断不符合的 16例进行分析。结果　脑膜瘤误诊为其他肿瘤的共 10例 ,占 6.5 % ;其他肿瘤误诊为脑膜瘤的共 6例 ,占4%。总误诊率为 10 .5 %。结论　因组织学结构复杂、设备性能和扫描技术 ,构成了MRI对脑膜瘤误诊的不可避免性 ;而舍弃年龄、部位的先入思想、注重典型特征、仔细阅片及善用病史等 ,又是提高符合率的关键。

MRI Misdiagnosis Analysis of "Meningioma"

Objective To study the distance of MRI in the practice of correct diagnosed meningioma.Methods 152 cases which have been diagnosed meningioma from MRI scan compared to operation and pathology.16 cases which do not fit the diagnosis from them were analysed.Results There were 10 cases which were misdiagnosed other tumour(6.5%).Other tumour misdiagnosed meningioma were 6 cases(4%).The general misdiagnostic rate was 10.5%.Conclusion Because of complexity in histological structural,equipment function and scan technology,it is inevitable to misdiagnose.If we can pay more attention to the typical character and study the plain film and medical history taking carefully,we could increase correct diagnostic rate of meningioma.
