Acute palsy of the recurrent laryngeal nerve complicating Epstein-Barr virus infection.

We report an 11-year-old boy with active Epstein-Barr virus (EBV) infection who developed acute aphonia and had signs and symptoms of recurrent laryngeal nerve palsy. The association of isolated recurrent laryngeal nerve palsy and EBV infection has not previously been reported. This case report expands the spectrum of neurologic complications of EBV infection, and suggests that infectious mononucleosis should be considered in the differential diagnosis of acute aphonia in children.
