Second: then, blood and cerebrospinal fluid examination: white blood cells were normal or slightly increased, mainly lymphocytes. C-reactive protein was not high. Normal or increased pressure, clear or slightly turbid appearance, normal or slightly increased white blood cell count, mainly lymphocytes, normal or slightly increased protein, normal sugar and chloride. No bacteria were found in CSF direct images.

Third: neuroimaging examination: because of its higher resolution, head MRI can more accurately show the location, nature and degree of various viral encephalitis lesions than CT, such as brain edema, cerebral hemorrhage, encephalomalacia and demyelinating lesions. Diffusion weighted imaging (DWI) is more sensitive than t1w1 or t2w2 in detecting the lesions of acute viral encephalitis, and can detect the abnormal signal of viral encephalitis in the early stage. It is suggested that MRI should be reexamined 3-4 weeks after the course of disease, which is helpful to judge the long-term prognosis.
