A Term Newborn with Lung Collapse since Birth

Respiratory distress in a term newborn has a wide range of differential diagnoses. Lobar lung collapse as a cause of respiratory distress in a term newborn always raises the suspicion of congenital pneumonia but it is challenging to determine if (1) it presents since birth, (2) it has a migratory nature, and (3) infection was excluded as a cause. We report a case of lobar lung collapse in a full-term baby and present our management of the case until the underlying diagnosis was reached.
