Internal laryngopyocele presenting as acute airway obstruction

Abstract

A laryngopyocele forms when a laryngocele becomes infected and fills with mucopus. We report a case of an internal laryngopyocele that presented as airway obstruction in a 34-year-old man; such a presenting sign is exceedingly rare. We also review the anatomy, etiology, and clinical course of the different types of laryngoceles.
