case_images: Head MRI on January 05, 2024-01 showed abnormal signal lesions in bilateral fronto-parietal subcortical cortex, right temporal lobe and right cerebellar hemisphere. Patchy long T1 and long T2 signal shadows were found in the right temporal lobe and right cerebellar hemisphere, FLAIR showed high signal, DWI and ADC showed equal signal, and scattered patchy long T1 and long T2 signal signals were found in the bilateral fronto-parietal subcortical cortex. FLAIR showed hyperintensity, DWI and ADC showed isointensity.

case_images: The head magnetic resonance imaging (MRI) was performed again at the local hospital, which showed abnormal signal lesions in the bilateral frontoparietal subcortical cortex, right temporal lobe, and right cerebellar hemisphere (Figure 1).
case_images: Head enhanced MRI on January 07, 2024-01: Scattered speckle-like slightly long T1 and slightly long T2 signal in bilateral frontoparietal and periventricular white matter, FLAIR sequence showed high signal, DWI showed no obvious high signal, no obvious enhancement. Patchy long T1 and long T2 signals were seen in the right temporal lobe and right cerebellar hemisphere, which were hyperintense on FLAIR sequence. DWI showed no obvious hyperintense signal and no obvious enhancement. A circular long T1-long T2 signal was seen in the right temporal base, with clear borders, measuring approximately 18 x 12 mm, and no enhancement.

case_images: Enhanced MRI of the head on January 7, 2024 showed abnormal signals in the lateral temporal lobe and the right cerebellar hemisphere, demyelinating lesions were considered, and encephalitis was considered (Figure 2).
