Combined sequestration, bronchogenic cyst, and dysgenetic lung simulating congenital lobar emphysema.

We report the case of a newborn with bronchopulmonary sequestration, bronchogenic cyst, and dysgenetic lung that radiographically simulated congenital lobar emphysema. We discuss congenital malformations of the lungs and the concept of a continuum in the development of pulmonary anomalies.
