摘要
目的：探讨病毒性脑炎不典型影像学表现及分型，以提高诊断准确率。材料和方法：回顾性分析确诊的439例病毒性脑炎中79例影像学表现不典型的影像资料。79例患者均行MRI平扫及DWI扫描，67例行增强扫描，12例病灶区行二维多体素MRS检查，54例行CT平扫，32例行增强扫描。结果：不典型影像学表现的病毒性脑炎分为单发脑实质型、边缘系统及灰质核团型和弥漫型，各型均有不同的影像学表现。结论：不典型表现的病毒性脑炎通过选择合理的影像检查技术，结合以上分型、临床及其影像学表现，诊断并不困难。
Abstract
Objective: To discuss the atypical radiological appearances and typing of viral encephalitis, in order to improve the diagnosing accuracy rate. Materials and Methods: Retrospectively analyzed the radiological data of 79 atypical radiological appearances of viral encephalitis in 439 diagnosed cases. All of the 79 cases experienced MRI plain scan and DWI examination, contrast enhancement were performed in 67 cases, two-dimension multi-voxel MRS examination in 12 cases; CT plain scan performed in 54 cases, CT contrast enhancement in 32 cases. Results: The viral encephalitis with atypical radiological appearances can be divided into single brain lobe type, limbic system and grey matter nucleus type, and diffuse type. The radiological appearances of different types are various. Conclusion: By choosing rational radiological examination technique, combined with the typing, clinical and radiological appearances, the diagnosis of viral encephalitis can be obtained.
