Acute vestibular syndrome in cerebellar stroke

Abstract

The current paper reports on a patient with recurrent rotational vertigo and persistent dizziness and imbalance lasting several weeks, who underwent extensive neuro-otological and radiological examinations. Pathological findings initially included right-sided benign paroxysmal positional vertigo (BPPV), persistent horizontal spontaneous nystagmus (SPN) to the left, and a pathological bedside and video head impulse test (HIT) on the left. The pathological HIT on the left and the SPN to the left indicated a central origin. Therefore, cranial magnetic resonance imaging was performed which revealed a left-sided ischemic stroke in the territory of the medial branch of the posterior inferior cerebellar artery (mPICA).
