MRI of the brain revealed confluent symmetrical abnormal increased T2-weighted (T2W) and fluid attenuated inversion recovery (FLAIR) signal involving cerebellar white matter, middle and superior cerebellar peduncles, cerebral peduncles, medial midbrain, posterior limb of internal capsule, external capsules, corona radiata, medial thalami, and dorsal aspect of pons [Figure 1].
Diffusion weighted images reveal restricted diffusion with hyperintense signal involving bilateral para-sagittal parietal regions, body and splenium of corpus callosum, external capsules, thalami and cerebellar peduncles (2A D). Corresponding ADC images show corresponding decreased signal in the above mentioned lesions (2E-2H)

Restricted diffusion was noted within the lesions with hypointensity on apparent diffusion coefficient (ADC) images [Figure 2].
MRI done after 1 week, diffusion weighted images reveal progressive restricted diffusion with hyperintense signal (arrows) involving parietal-temporal cortex and subcortical white matter, body and splenium of corpus callosum, external capsules, thalami and cerebellar peduncles. (3A-3D)

It revealed progression of the lesions with involvement of cortex and subcortical white matter in the bilateral frontoparietal regions with persistent diffusion restriction [Figure 3].
