Severe Influenza B-associated Encephalopathy With Vocal Cord Paralysis in an Otherwise Healthy Adolescent: A Case Report

Influenza B is generally considered a mild respiratory virus, but this case demonstrates its potential for severe neurological complications in otherwise healthy individuals. We describe a 17-year-old male patient who developed encephalopathy and bilateral vocal cord paralysis, requiring intensive care and tracheostomy. The patient gradually recovered following supportive care and multidisciplinary rehabilitation. This report highlights the importance of recognizing rare complications during influenza outbreaks.
