One minute Fact Sheet

What is a congenital lung malformation?

A congenital lung malformation (CLM) is a rare condition where part of a baby’s lungs did not develop normally during pregnancy. CLMs are not associated with chromosomal abnormalities and are not caused by anything the mother did or didn’t do during pregnancy. The two most common types of lung malformation are CPAM and BPS.

What is CPAM?

CPAM (congenital pulmonary airway malformation) is an abnormal mass of lung tissue, normally affecting one lung lobe. The CPAM is part of the lungs and connected to the lung’s blood supply. 

What is BPS?

Like CPAM, a BPS (bronchopulmonary sequestration) is an abnormal growth of lung tissue, but unlike CPAM, the mass is not connected to the lung’s blood supply. Instead, the BPS is connected to a nearby systemic vessel, normally the aorta. 

What is the prognosis for someone born with a congenital lung malformation?

The prognosis is excellent. In the overwhelming majority of cases a lung malformation will not affect a child’s life expectancy or quality of life. In some rarer cases, the lung malformation can present more serious complications during pregnancy or immediately after birth.

What are other types of CLM?

Bronchogenic cysts, congenital lobar emphysema (CLE), and congenital bronchial atresia (CBA) are rarer types of congenital lung malformation. A lung malformation can also show characteristics of more than one type e.g. a mixture of CPAM and BPS. These are called hybrid lesions.
