Department ofNeurology"Basic Information"male, 27-year-oldfever for three days, mental disorders day"Image)"Discuss the problem"diagnosis?Discussion"comment: left island, temporal cortex swelling, flaky slightly longer T1, slightly longer T2 signal, boundary blur, enhanced scanning did not see significant reinforcement, in line with the encephalitis image performance's "Clinical Feedback Results"Viral encephalitis"case summary"viral encephalitis is a common central nervous systeminfection disease, is mainly infected with the brain, and often affects the meninges (meninges encephalitis), and sometimes can be affected by the spinal cord and nerve roots (encephalomyelitis, cerebrospinal cord neurogenitis) Patients with viral encephalitis have clinical manifestations of fever, headache, vomiting and meninges stimulation, which are diverse and not typical, and diagnosis is mainly through virology and immunology the pathological characteristics of viral encephalitis are the limitationor or diffuse edema of gray matter in the cerebral cortex and sub-skin, the formation of nerve cells with widespread degeneration, necrosis and small softening stoves, and the formation of glial cell growth to form nodules MRI is very sensitive to pathological changes in edema and has high resolution on gray matter lesions, so MRI can provide valuable diagnostic information for clinical use to show lesions and to understand the areas, extent, extent, lesions and morphology of lesions MRI performance: brain multiple or single lesions, more common in the two sides of the brain hemispheric forehead, crucible, top, pillow lobe and base section area, thalamus, mostly asymmetry distribution, mainly located in the cortex and sub-cortex, mainly gray matter, white matter can be affected at the same time The lesions were mostly patchy, brain-reflux and speckle changes The lesions are low signal slower in T1WI, part uneven, combined bleeds have high signal, T2WI is high signal, FLAIR sequence lesions are high signal and the boundary is clearer The reinforcement is mostly patchy, brain-return-like reinforcement, and a few are speckled and ring-shaped There is no reinforcement in the early stages of the lesions Source: Image Park
