Figure 4. (A) Brain magnetic resonance imaging (MRI) on the second hospital admission (week 7) revealed non-enhancing confluent areas of abnormal T2-weighted signals in the bilateral middle cerebellar peduncle, pons, left>right cerebellar hemisphere, and right thalamocapsular and midbrain regions. (B) Brain MRI on the second hospital admission (week 7) showed corresponding non-enhancing T1-weighted hypointensities in the bilateral middle cerebellar peduncle, pons, left>right cerebellar hemisphere, and right thalamocapsular and midbrain regions.
