Case Report

Abstract

A 63-year-old female with no significant past medical history was presented with a 5-day history of progressive opsoclonus-myoclonus, headaches, and fevers. Her workup was significant only for positive West-Nile Virus serum serologies. She received a 2-day course of intravenous immunoglobulin (IvIG). At an 8-week follow up, she had a complete neurological remission. Adult-onset opsoclonus-myoclonus syndrome is a rare condition for which paraneoplastic and infectious causes have been attributed. To our knowledge, this is the first case reported of opsoclonus-myoclonus secondary to West-Nile Virus treated with intravenous immunoglobulin monotherapy.

Video 1

The first part of the video shows the clinical findings of this patient at presentation. Significant opsoclonus is first demonstrated in all directions of gaze. Myoclonus of the hands and mouth can be observed. In the second part of the video, we can appreciate that the patient has achieved a full neurological recovery. Standing up from a chair, tandem gait, and extra-ocular movements are normal. (MPG 44386 kb)
