case_images: Multiple patchy and small patchy abnormal signals observed in both cerebral hemispheres, showing low signal on T1-weighted imaging (T1WI), high signal on T2-weighted imaging (T2WI), and high signal on diffusion-weighted imaging (DWI), suggesting the possibility of encephalitis.

case_images: A 1d head magnetic resonance imaging (MRI) showed multiple abnormal signals in bilateral cerebral hemispheres, raising the possibility of encephalitis (Figure 1).
case_images: (a and b) Multiple patchy and small patchy abnormal signals observed in bilateral cerebral hemispheres, basal ganglia, and thalamus showing low signal on T1-weighted imaging (T1WI), high signal on T2-weighted imaging (T2WI), and high signal on diffusion-weighted imaging (DWI) (c and d). Abnormal signal of the corpus callosum.

case_images: fig2-2050313X231211713
case_images: A head MRI on day 8 showed multiple abnormal signals in the bilateral cerebral hemispheres, basal ganglia region, thalamus, and corpus callosum, indicative of encephalitis (Figure 2).
case_images: (a and b) The bilateral brain is symmetrical and small in size, and the lamellar T1-weighted imaging (T1WI) shows low signal, the T2-weighted imaging (T2WI) shows high signal, and the diffusion-weighted imaging (DWI) shows low signal, the bilateral basal ganglia is reduced in shape, the structural boundary is unclear, and the bilateral cerebral sulci, brain cleft, and extracerebral space are generally widened, suggestive of bilateral atrophic-like brain changes. There are multiple softening foci in bilateral cerebral hemispheres.

case_images: fig3-2050313X231211713
case_images: Another head MRI at 19 days showed bilateral brain atrophy-like changes and multiple softening foci in bilateral cerebral hemispheres; these were considered residual changes after brain injury (Figure 3).
