Antenatal Diagnosis and Management of Congenital Pulmonary Airway Malformation: A Case Report

Congenital pulmonary airway malformation (CPAM) is a rare developmental lung anomaly that can be identified on prenatal ultrasonography. We report a case of antenatally diagnosed CPAM with a progressively increasing CPAM volume ratio (CVR) on serial foetal imaging. Antenatal corticosteroids were administered, and a male neonate was delivered by elective lower-segment caesarean section at 33 weeks of gestation. Postnatal imaging confirmed CPAM involving the right middle lobe. The infant underwent right middle lobectomy on postnatal day nine with an uneventful postoperative course. This case highlights the importance of serial CVR monitoring, antenatal planning, and timely surgical management in achieving favourable outcomes in high-risk CPAM.
