Congenital Parenchymal Lesions of the Lung

Increasing use of ultrasonography during pregnancy has uncovered a range of parenchymal lesions within the lung, some of which will, if left, be a cause of morbidity and occasional mortality. These include congenital cystic adenomatoid malformations (CCAM), bronchopulmonary sequestration (BPS), congenital lobar & segmental emphysema and bronchogenic cysts. Adverse antenatal features include mediastinal shift, caval obstruction, and (rarely) hydrops. This review aims to define current thoughts on these lesions and suggest appropriate management.
