Infectious Mononucleosis Causing Bell’s Palsy: A Case Report

Infectious mononucleosis, also called the kissing disease or "mono," is typically caused by the Epstein-Barr virus. It is a clinical condition marked by fever, lymphadenopathy, and pharyngitis. Bell's palsy is a condition that causes sudden, temporary facial paralysis, or weakness on one side of the face. It can have various etiologies, such as congenital, neurological, infectious, neoplastic, or traumatic. This report describes the case of an 18-year-old female who was diagnosed with Bell's palsy, a rare neurological complication of Epstein-Barr virus-associated infectious mononucleosis. This instance highlights a unique manifestation of facial nerve palsy, which is atypical in cases of mononucleosis.
