Neuroradiologic MRI (1.5 T) of Patient 1. The bilateral temporal lobes and bilateral hippocampus showed hypointensity on T1WI and hyperintensity on T2WI and FLAIR. Notably, they were more pronounced in the left side (A). After two months, the bilateral temporal lobes and bilateral hippocampus showed a slightly lower signal on T1WI and a slightly higher signal on T2 and FLAIR. Notably, they were more pronounced in the left side (B).

T1 weighted image (T1WI) in the bilateral temporal lobes and hippocampus with dominance in the left side (Figure 1A). In a follow-up of three months after treatment, brain MRI imaging showed that the brain lesion improved (Figure 1B).

Neuroradiologic MRI (3.0 T) of Patient 2. The left temporal lobe and hippocampus showed hypointensity on T1WI and hyperintensity on FLAIR.
