| 摘 要： | 目的分析急性病毒性脑膜脑炎的MRI和CT表现,探讨两者在急性病毒性脑膜脑炎中的诊断价值。方法收集经临床诊断病毒性脑膜脑炎病例共43例,除1例仅行CT平扫外,其余42例均行MRI和CT扫描。结果 MRI发现病变32例（32/42）,CT发现病变19例（19/43）,大脑、小脑和脑干均可发病,好发于颞叶、额叶,多呈散在分布,无明显占位效应或仅表现为轻度占位效应,CT平扫呈片状、斑片状边缘不清低密度影,MRI表现T1WI呈等或稍低信号,T2WI、弥散加权（DWI）和T2WIFlair呈高信号,增强扫描呈脑回状明显强化。结论 MRI和CT对病毒性脑膜脑炎诊断有帮助作用,MRI可作为病毒性脑膜脑炎的首选检查。

| Abstract: | Objective To study the manifestation of acute viral meningoencephalitis on CT and MRI, and evaluate their value in diagnosis of acute viral meningoencephalitis. Methods Collect the imaging and clinical data of 43 cases with acute viral meningoencephalitis; CT and MRI were performed in all patients except for one who died and only underwent CT plain scan. Results Lesions in 32 cases were found by MRI, lesions in 19 cases were found by CT, and the lesions may locate in cerebrum, cerebellum and brainstem, pred... |
