A 2-year-old previously healthy girl was brought to her pediatrician with the chief complaint of persistent noisy breathing. Two months earlier, the child had an upper respiratory tract infection (URI) with rhinorrhea, cough, noisy breathing, and wheezing. All symptoms had resolved except the abnormal breathing. Physical examination findings were unremarkable. A lateral neck x-ray film demonstrated subglottic narrowing, thought to be consistent with croup. Laryngoscopic examination by an otolaryngologist did not reveal any pathology.
