Acute airway obstruction, an unusual presentation of vallecular cyst.

A 18-year-old female presented to us with acute respiratory obstruction, unconsciousness, severe respiratory acidosis, and impending cardiac arrest. The emergency measures to secure the airway included intubation with a 3.5-mm endotracheal tube and railroading of a 6.5-mm endotracheal tube over a suction catheter. Video laryngoscopy done after successful resuscitation showed an inflamed swollen epiglottis with a swelling in the left vallecular region, which proved to be a vallecular cyst. Marsupialisation surgery was performed on the 8(th) post admission day and the patient discharged on 10(th) day without any neurological deficit.
