Eurorad Case: Olivopontocerebellar Atrophy Imaging Features

This Eurorad teaching case illustrates the classic neuroimaging findings of olivopontocerebellar atrophy, a form of multiple system atrophy (MSA-C), characterized by prominent atrophy of the pons, middle cerebellar peduncles, and cerebellum on MRI.

• The case demonstrates the characteristic "hot cross bun" sign in the pons, seen in MSA-C.
• This is a teaching file intended for radiology trainees and practicing radiologists to review the MRI spectrum of neurodegenerative ataxias.
• The content is educational and does not report new research findings or clinical trial data.
