Bilateral facial nerve palsy associated with Epstein-Barr virus infection with a review of the literature

Abstract
A case of bilateral simultaneous facial nerve palsy associated with an Epstein-Barr virus (EBV) infection in a 14-month-old girl is described. Diagnosis of the EBV infection was based on the presence of 7% atypical lymphocytes, EBV-DNA and seroconversion in the VCA-IgG antibody, an EBV-specific antibody. Although bilateral facial nerve palsy is very rare, approximately 40% of the EBV-associated facial nerve palsy cases reported have been bilateral.
