Purpose or Case Report: Congenital anomalies of lungs are heterogenous group of developmental disorders which vary widely in their clinical manifestations, imaging appearance and pathology, but with a considerable overlap. There has been substantial improvement in our understanding of these lesions due to advances in prenatal and postnatal imaging. The purpose of this educational exhibit is to describe the radiological appearance of various congenital lung abnormalities and facilitate our fellow radiologists to accurately diagnose these anomalies and contribute to the patient management.
Methods & Materials: We present a spectrum of cases with postnatal imaging using various modalities like plain radiographs, ultrasound, CT and MRI. The key imaging features are also highlighted along with relevant differential diagnosis, wherever applicable. The abnormalities are classified as predominantly parenchymal, predominantly vascular, and combined parenchymal and vascular anomalies. The anomalies described include bronchial atresia, tracheal bronchus, bronchogenic cysts, congenital lobar overinflation, congenital pulmonary airway malformations (including evaluation of DICER mutation) , bronchopulmonary sequestration, hypogenetic lung syndrome, anomalies of pulmonary artery and veins as well as hybrid lesions. Each anomaly is evaluated based on it’s location, internal architecture, vascular supply and drainage, airway abnormality, and other congenital associations.
Results:
Conclusions: A thorough understanding of congenital lung anomalies and their appearance on various imaging modalities is imperative for radiologists in improving diagnostic accuracy and patient management.
