Radiographically occult congenital lobar emphysema presenting as unexplained neonatal tachypnea

Pediatr Pulmonol. 2001 Sep;32(3):246-9. doi: 10.1002/ppul.1114.abs.


Congenital lobar emphysema (CLE) is usually diagnosed in the newborn period in an infant with respiratory difficulties and classic X-ray film findings. We describe a neonate with tachypnea of unclear etiology who was diagnosed with CLE by chest computed tomography scan, despite a plain chest radiograph that did not suggest the diagnosis.
