Figure 4: MRI axial T2-weighted (a) and diffusion-weighted (DWI) (b) images demonstrate the old infarction in the left superior cerebellar hemisphere and the new lesion in the right superior cerebellar hemisphere with identical distribution. The restricted diffusivity (high signal intensity in (b)) indicates a recent infarction.
