However, these subtypes share common histopathological changes, characterized by neuronal loss, gliosis and the presence of glial cytoplasmic inclusions (GCI) with a-synuclein.5 In MSA-P the degenerative changes predominantly affect the basal ganglia, particularly the putamen seen as hyperintense rim at the putaminal edge, atrophy and hypointensity of putaminal body on T2WI while in MSA-C changes predominantly affect infratentorial structures like pons and cerebellum, seen as atrophy and hyperintense signals in pons, cerebellum and middle cerebellar peduncles with pontine hyperintensity (hot cross bun sign) on axial image,4 which was seen in both of our patient's MRI.
