Radiological characterization of spinocerebellar ataxia type 6

Spinocerebellar ataxia type 6 (SCA-6) is a rare, autosomal dominant neurodegenerative condition characterized by adult onset cerebellar ataxia and ocular movement disorders. The presentation is non-specific, and radiological characterization would be of diagnostic benefit. There is little published on the radiological appearances of SCA-6, and there are conflicting reports in the literature. We report the radiological findings in a group of 10 patients with SCA-6.
