Myelin oligodendrocyte glycoprotein antibody‐associated disease presenting with dystonia

Abstract

Abstract Myelin oligodendrocyte glycoprotein antibody‐associated disease (MOGAD) commonly presents as optic neuritis or transverse myelitis. We report an atypical clinical presentation for MOGAD in a 28‐year‐old female experiencing right‐arm dystonic episodes. MRI scans demonstrated multifocal periventricular and subcortical lesions, including in the left centrum semiovale and corona radiata. Despite the atypical presentation, her clinical, serological, and radiographic features favor a MOGAD diagnosis. This report emphasizes the heterogeneity of MOGAD phenotypes and the need to consider MOGAD, even in a non‐typical presentation.
