Sequential chest radiographs of bronchopulmonary dysplasia (BPD) in a premature infant

Image A is a chest radiograph taken after birth of a premature infant born at 25 weeks. The lungs are clear. Image B is a chest radiograph taken two weeks later, which shows a coarsened interstitial pattern and diffuse haziness. Image C is a radiograph that shows further coarsening of the lung markings five weeks after birth. Image D shows pulmonary congestion after closure of a patent ductus arteriosus (arrow shows clip). Image E is a magnification of image D and shows cystic changes in the lungs (arrows).
