Postnatal Imaging Diagnosis of Congenital Cystic Lung Disease

Congenital cystic lung diseases (CCLD) include several diseases, such as congenital bronchial atresia, congenital lobar emphysema, congenital pulmonary airway malformation, bronchopulmonary sequestration and bronchogenic cyst. Prenatal diagnosis of congenital lung diseases is widespread and postnatal imaging diagnosis of CCLD is important for patient management and treatment decisions. It is necessary to know their radiological manifestations, especially parenchymal abnormalities included cysts and air-trapping, vascular supply and drainage of the lesions and bronchial abnormalities, to appropriate diagnosis. Radiographs play a role in the detection and initial postnatal imaging evaluation in clinically suspected CCLD, and CT and MRI are required for confirmation of diagnosis and preoperative evaluation of surgical lesions.
