Brain MRI: 1. Hyperintensity is observed on T2-FLAIR sequences in the bilateral cerebellar hemispheres (yellow arrows), with marked asymmetric (left > right) distribution. 2-3. Hyperintensity is observed in DWI (2) and ADC (3) sequences, without clear restriction, which suggests of vasogenic edema at this level.

Given the rapidly progressing ataxia and epilepsy, we performed a brain MRI, which showed T2 hyperintensity in the cerebellar hemispheres (Figure 1), suggestive of vasogenic edema.
