Brain MRI Demonstrating Cerebellar Inflammation. (A) Brain magnetic resonance imaging (MRI), axial view, fluid-attenuated inversion recovery sequence showing high signal intensity in the cerebellar hemisphere with dilatation of temporal horns of the lateral ventricles due to hydrocephalus. (B) MRI brain, axial view, post-contrast T1-weighted sequence demonstrating prominence of perforating vessels in the cerebellar hemispheres but no apparent parenchymal enhancement. A and B scans were obtained at the initial presentation. (C) Brain MRI, axial view, FLAIR sequence. This scan was done 20 days from disease onset. It shows subtle increased T2 signal within the bilateral cerebellar hemispheres, improved, in comparison with previous studies. It also shows improvement of the hydrocephalus.

Brain magnetic resonance imaging (MRI) on admission showed cerebellar edema and hydrocephalus (Figure 1).
Brain MRI Demonstrating Cerebellar Atrophy. (A) Brain magnetic resonance imaging (MRI), sagittal view, T1-weighted image at the level of midline cerebellum, this image was obtained at the initial presentation. (B) Brain MRI, sagittal view, T1-weighted image. This is a follow-up MRI at 6 months after disease onset showing significant cerebellar atrophy.

Brain MRI 6 months from disease onset showed significant cerebellar atrophy (Figure 2).
