There is symmetric marked hyperintense signal intensity on T2/FLAIR imaging and restricted diffusion in the dentate nuclei, inferior cerebellar peduncles, lateral fourth ventricle floor in the expected locations of the vestibular tract and in the expected tract of the vestibular cochlear nerve. Also present, is diffusion restriction in the posterior columns of the proximal cervical cord, anteriorly in the inferior medulla, and punctate symmetric foci of restricted diffusion in the inferior colliculi of the quadrigeminal plate and medial geniculate bodies. There is mild high signal on FLAIR and diffusion weighted imaging involving the bilateral putamen.
