Congenital cystic adenomatoid malformations (CCAM) of the lung are rare congenital cys-tic lung lesions that arise from excessive disorganized proliferation of tubular bronchial structures. The prenatal rate of detecting lung cysts at the routine 18–20-week scan is almost 100%.However as gestation progresses the tracheobronchial tree becomes patent and the fluid within the cysts exits into the amniotic fluid and the cysts collapse, allowing the other lobes of the lung to develop normally. Only at birth do the cysts then expand and present in the newborn period with respiratory distress. In late childhood or in adult life, it can present as recurrent chest infections or even undergo malignant transformation. We report a case of Type II CCAM in newborn with brief review of literature.
