Abstract

We report a patient with an isolated cerebellar nodulus infarction who presented with periodic alternating nystagmus (PAN), perverted head-shaking nystagmus (pHSN), and loss of tilt suppression of the vestibulo-ocular reflex (VOR). Several days after the initial symptoms resolved, the patient also presented with purely vestibular syndrome with vertigo, spontaneous horizontal nystagmus without the usual signs of cerebellar dysfunction. The chain of those symptoms were ascribed to ischemia of the cerebellar nodulus. KeyWords:Nodulus, Periodic alternating nystagmus (PAN), Unilateral vestibulopathy
