Spinocerebellar ataxia type 6 (SCA6) is an autosomal dominant, slowly progressive cerebellar ataxia without multisystem involvement. We report a 57-year-old woman with genetically confirmed SCA6 who showed clinical features of olivopontocerebellar atrophy. Conventional T2-weighted and FLAIR MRI demonstrated high signal in the middle cerebellar peduncles, in addition to mild atrophy of the pons and cerebellum.
6型脊髓小脑共济失调（SCA6）是一种常染色体显性遗传、缓慢进展的小脑共济失调，不累及多系统。我们报告了一名57岁经基因确诊为SCA6的女性，其表现出橄榄脑桥小脑萎缩的临床特征。传统的T2加权和液体衰减反转恢复序列（FLAIR）磁共振成像（MRI）显示，除脑桥和小脑轻度萎缩外，小脑中脚呈高信号。
