CXR: Hyperinflation with clear lung parenchyma except for perihilar linear densities and fluid in the fissures, no consolidations.
Presenting complaints: Acute and persistent respiratory illnesses (51%), failure to thrive or malnutrition (43%), abnormal stool or steatorrhea (35%)
Due to immature alveolar cells that produce less surfactant, decreased compliance, atelectasis, lung tissue ischemia, sloughing of tissue and edema.
