Movement degraded study. Diffuse atrophy, most marked in the posterior fossa with there is prominence of the cerebellar folia and fourth ventricle. Relative sparing of the middle cerebellar peduncle is which demonstrates abnormally increased T2 and FLAIR signal (MCP sign).
The medulla is atrophic however the pons appears of normal volume although there is increased T2 signal within the transverse fibres of the pons.
Further confluent abnormal increased T2 and FLAIR signal in the periventricular and subcortical white matter of the cerebral hemispheres including the splenium of the corpus callosum. The cerebral hemispheres also demonstrate atrophy which is most marked in the parietal regions. No evidence of diffusion restriction.
