This MRI suggests possible multiple system atrophy of cerebellar type (MSA-C). Atypical Parkinson's syndromes are important to detect on imaging as they are unresponsive to levodopa.

MSA presents as a variable combination of parkinsonism, cerebellar ataxia, and/or autonomic failure such as orthostatic hypotension. Striatonigral degeneration (SND) is now known as MSA-P, olivopontocerebellar atrophy (OPCA) is now known as MSA-C. Both MSA-P and MSA-C may have variable components of SDS.
