A Case of Infectious Mononucleosis with Upper Airway Obstruction

Serious complications of infectious mononucleosis, including upper airway obstruction, have been reported, although they are rare. Herein, we report the case of a 25-year-old woman who was suspected as having upper airway obstruction on day 5 after the onset of infectious mononucleosis. Tracheostomy was planned to secure the airway, but fortunately, the patient recovered with conservative treatment. There have been several reports in the past of upper airway obstruction developing in patients with infectious mononucleosis, and some cases have had unfortunate outcomes. It is necessary to consider the possibility of progression of upper airway obstruction and take all possible measures to manage the airway in patients with infectious mononucleosis.
