Direct Visualization of Congenital Pulmonary Airway Malformation by Neonatal Point-Of-Care Lung Ultrasound.

Congenital pulmonary airway malformation (CPAM) is usually assessed prenatally and further characterized postnatally with cross-sectional imaging. Direct visualization by lung ultrasound may be limited when normally aerated lung overlies the lesion. We report a term (39 weeks' gestation) neonate with a prenatally suspected CPAM in whom bedside point-of-care ultrasound directly demonstrated a peripheral heterogeneous multicystic lesion in the left lung. This case illustrates the characteristic sonographic appearance of a pleural-accessible CPAM and highlights lung ultrasound as a rapid, radiation-free adjunct for bedside assessment while emphasizing that a normal ultrasound examination cannot exclude a deeper congenital lung malformation.
