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.
