A 76-year-old man with a history of memory impairment and parkinsonism including gait and proprioceptive dysfunction. Fluorodeoxyglucose PET/CT demonstrates hypometabolism in the right greater than left cerebellar hemispheres (a) and bilateral striatum (b), best appreciated on ss-SPM (areas of blue and purple representing negative deviation in uptake from controls, d). Iodine-123-FP-CIT scan shows left greater than right primarily putaminal presynaptic neuronal degeneration (c). Findings are compatible with MSA-P. Axial T2 FLAIR image of a separate patient demonstrates the lateral putaminal rim sign of hyperintensity (arrows in e)
