A case of Epstein-Barr virus infection complicated with Guillain-Barré syndrome involving several cranial nerves.

This report presents a case of infectious mononucleosis with severe neurological complications in a previously healthy young female. Both peripheral and cranial nerves were affected causing paralysis and need for assisted ventilation. There was a clear correlation between the symptoms and the serological findings, indicating that the causative agent was Epstein-Barr virus. The patient was treated with acyclovir, methylprednisolone and immunoglobulins. Two months later she had recovered completely. Epstein-Barr virus infection must be considered among the possible causes in patients with cranial nerve affection or Guillain-Barré syndrome.
