CT PULMONARY EMBOLUS AND DIFFUSE LUNG DISEASE (T BUXI, SECTION EDITOR) Congenital Malformations and Developmental Anomalies of the Lung

Congenital malformations of the lung are a group of diverse, yet related, abnormalities which may involve the lung parenchyma, pulmonary vasculature, or a combination of both. They may be detected in fetal life, produce severe symptoms during infancy, or may not manifest symptomatically until adulthood. The goal of imaging is to demonstrate the various components of the malformation, to facilitate appropriate management. This article discusses the spectrum of congenital and developmental lung anomalies, their etio-pathogenesis, role of various imaging modalities, and characteristic radiological findings.
