A 17-year-old boy was seen in the emergency department with signs and symptoms of acute upper airway obstruction, closely resembling epiglottitis. Inunediate management consisted of induction of general anesthesia with spontaneous ventilation. Because no organic pathologic process was found, and in combination with subsequently known psychosocial stressors, a diagnosis of psychogenic stridor, a conversion disorder, was made. Conversion disorders may be seen by the busy family practitioner or pediatrician and are frequently underdiagnosed.
