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.

A significant association was found between plasma ApoA1 and putaminal dopamine transporter (DAT) uptake, and it was also confirmed that lower ApoA1 level was related with more severe DAT deficit, even adjusting the confounding factor.[31] Hence, the level of ApoA1 could possibly reflect the severity of motor impairment based on the concept that the level of DAT uptake could reflect motor impairment extent.
