Unilateral Facial Palsy in an Adolescent with Guillain–Barré Syndrome

Abstract

Guillain–Barré syndrome (GBS) is the most common and most severe acute demyelinating polyneuropathy with ∼0.8 to 1.1/100,000 incidence in pediatric population. Unlike adult patients, incidence of facial nerve involvement in children with GBS has not yet been determined possibly because of rare use of magnetic resonance imaging in childhood-onset GBS. In the present study, we describe a girl with GBS who presented unilateral peripheral facial palsy, confirmed by neuroimaging and electrophysiological evaluation. We suggest that both neuroimaging and detailed electrophysiological evaluation should be integrated into the work-up of such patients. We also wish to highlight the importance of evaluating cranial nerve involvement as a potential indicator of severity of disease.
