| 摘 要： | 目的：分析不同脑膜病变的MRI表现，探讨MRI对不同病因所致脑膜异常强化的诊断价值。资料与方法：对58例MR增强扫描显示脑膜异常强化的病例进行回顾性分析。结果：按脑膜强化方式分为：硬脑膜－蛛网膜强化21例，软脑膜－蛛网膜下腔强化37例。按病因不同分：感染性脑膜炎16例，脑梗死21例，脑膜癌病12例，硬膜下积液或血肿5例，开颅术后4例。结论：MRI增强扫描有助于显示脑膜病变，全面分析MRI表现及结合临床对鉴别不同病因的脑膜病变具有重要作用。

| Abstract: | Objective To analyze MRI manifestations of different meningeal disorders, and to evaluate MRI in the diagnosis of abnormal meningeal enhancement due to different diseases.Materials and Methods Enhancement features in 58 cases with abnormal meningeal enhancement on MRI were retrospectively analyzed. Results Two patterns of meningeal enhancement were seen: (1) dura arachnoid enhancement (n=21) and (2) leptomeningo subarachnoid space enhancement (n=37). The disorders in this study included infective meningitis (n=16), cerebral infarction (n=21), meningeal carcinomatosis (n=12), subdural hydrops or hematoma (n=5) and post carniotomy (n=4).Conclusion Enhanced MRI scanning is useful in detecting meningeal disorders. A comprehensive analysis of MRI manifestations, combined with clinical information, is of great importance in determining the etiology of meningeal diseases. |
