Abstract

Abstract: We report a 68-year-old lady who presented with Huntington phenocopy with generalized chorea and was genetically proven to have Spinocerebellar ataxia (SCA)17. MRI Brain demonstrated motor band sign, which is most commonly reported in motor neuron disease. This is the first case of motor band sign with SCA 17 and highlights the widening spectrum of radiological signs in SCA 17. Highlights: Case of SCA 17 with 41 CAG/CAA repeats presenting as a Huntington phenocopy. First reported case of a Motor band sign seen in SCA 17. Documents that motor band sign can be seen in a neurodegenerative disorder like SCA17.
