Prenatal diagnosis and postnatal management of congenital pulmonary airway malformation

Congenital pulmonary airway malformation (CPAM) is a rare developmental lung abnormality. It is also referred as a congenital cystic adenomatoid malformation. The exact etiology is not known yet. The majority of cases are detected during targeted prenatal scan or within 2 years of the birth. Here, we report a case of CPAM type II diagnosed at 23 weeks of gestation, the key diagnostic features of which were mediastinal shift and lung lesion. The fetus had transient polyhydramnios and pericardial effusion. Glucocorticoids were administered for threatened preterm labor and CPAM. Healthy neonate was delivered at term without any immediate neonatal complications.
