Epstein-Barr virus-associated cerebellar ataxia

Abstract

Cerebellar ataxia is a common neurological presentation. It can be acute, subacute or chronic. Neurological complications of Epstein-Barr virus (EBV) are well-recognised with a variety of presentations. Acute cerebellar ataxia is a rare, but an established complication. It has been described as the sole manifestation of EBV infection without the systemic features of infectious mononucleosis. The pathophysiology is not clear. The course of the illness may last for a few months with a benign outcome, though serious complications can happen. We present a case of a 38-year-old man who presented with an acute cerebellar ataxia owing to EBV infection, along with a review of the literature. Copyright 2013 BMJ Publishing Group.
