Spinocerebellar ataxia type 8 (SCA8) is a relatively rare type of autosomal dominant hereditary spinocerebellar degeneration. Previously reported imaging findings have shown isolated cerebellar atrophy. We herein report the case of a patient with a genetically confirmed diagnosis of SCA8 who exhibited T2 hyperintensity in the inferior olivary and dentate nuclei in addition to cerebellar atrophy. To the best of our knowledge, this is the first report of this specific imaging finding associated with SCA8, which may represent a characteristic imaging feature of the disease.
Fukuda et al. (Thu,) studied this question.
