Congenital pulmonary airway malformation: A case report of a rare cause of neonatal respiratory distress and review of the literature.

Congenital pulmonary airway malformation (CPAM), formerly known as congenital cystic adenomatoid malformation (CCAM), is a rare developmental dysplastic lesion of the fetal tracheobronchial tree. CPAM is a rare cause of neonatal respiratory distress; however, its presence may span fetal to adult period. In two previous case-reports from Nigeria, CPAM was present in post-neonatal infants. We report the case of a neonate, who presented with increasing respiratory distress and an abnormal chest radiograph, initially assumed as pneumonic changes. A revised diagnosis of CPAM was made after a chest computed tomography (CT) scan. The neonate subsequently had a successful excision of the affected lobe with remarkable clinical improvement. The case highlights the need to utilize superior imaging studies such as CT when plain radiographs are inconclusive.
