MRI study shows the following:
- multiple variable-sized patchy lesions are seen involving both cerebral hemispheres cortical and subcortical regions as well as the basal ganglia mainly seen at the bifrontal, bilateral parietal as well as right caudate & lentiform nuclei and thalamus.
- the involved regions appear swollen, and elicit signal alteration (low T1/ high T2 and FLAIR) with diffusion restriction in DWI. Gyriform/ leptomeningeal enhancement patterns are seen in the post-contrast study
- normal posterior fossa
- no hydrocephalus
