Introduction-

Prenatal diagnosis of echogenic lung lesions can be achieved using high-resolution ultrasound during the second trimester. The most common causative lesions are congenital pulmonary airway malformation (CPAM) and pulmonary sequestration (BPS). Few studies have described the prognosis and prenatal and postnatal management of these lesions. We hereby report the first of the two cases of CPAM managed successfully in Pakistan with favourable outcomes.

Methodology-

The first case of Primigravida presented at 20 weeks with echogenic lung lesions of microcystic and macrocytic type. Since it was unilateral with no signs of hydrops or polyhydramnios she was encouraged to continue the pregnancy. Later she had a planned delivery and delivered a healthy baby boy of 3 kg that remained asymptomatic through the antenatal period.

The second case is of a Multigravida patient who presented for second opinion at 22 weeks with a scan showing large macrocystic echogenic lesions occupying 50% of the right lung. She had been advised termination by multiple physicians but after the scan was reassured of the favourable outcome. She underwent a Caesarean section at term due to breach presentation and delivered a healthy and asymptomatic boy.

Conclusion- Antenatal presence of CPAM is usually associated with favourable outcomes and hence after detailed scans are performed to rule out any other associated anomalies parents should be reassured about the good prognosis and avoidance of termination of pregnancy.
