Bronchoscopic appearances of congenital lobar emphysema

Pediatr Pulmonol. 1996 Mar;21(3):195-7. doi: 10.1002/(SICI)1099-0496(199603)21:3<195::AID-PPUL9>3.0.CO;2-P.


Although decreased bronchial cartilage is found in 50% of cases of congenital lobar emphysema (CLE), it can only be surmised that this defect produces a ball valve effect with consequent overinflation. We describe the flexible bronchoscopic features of CLE in a 3-year-old child. The observed airway patency during inspiration, and dynamic airway collapse on expiration suggests that bronchomalacia contributes to lung overinflation in these cases.
