Congenital cystic adenomatoid malformation of the lung is an uncommon anomaly. Two patients with this condition were recently referred to the Otolaryngology Service at The Hospital for Sick Children, Toronto, Ontario, for bronchoscopic evaluation of the airway to rule out a foreign body. Although history did not disclose a clear episode of aspiration in either case, chest radiographs showed unilateral lobar hyperinflation with mediastinal shift, consistent with foreign body obstruction. We report two cases to introduce congenital cystic adenomatoid malformation to the English otolaryngology literature and to increase awareness of it among otolaryngologists.
