The pons has reduced volume with prominence of the prepontine cistern and fourth ventricle. The hot cross bun sign is present in the pons on FLAIR and T2-weighted images.
Diffuse widening of folia in both cerebellar hemispheres and the vermis and thinning and increased signal of both middle cerebellar peduncles. Relatively preserved cerebral hemispheric volume.
