CONGENITAL CYSTIC LUNG LESIONS
The 2 most common malformations of the lung are congenital cystic adenomatoidmalformation (CCAM) and bronchopulmonary sequestration (BPS). CCAM is ahamartomatous lesion, and BPS is a nonfunctioning bronchopulmonary segment separate from the tracheobronchial tree.
These conditions are followed by serial ultrasonography. Some resolve spontane-ously, though minimally invasive surgery may be required.
