Imaging findings
High-resolution chest CT in a 27-year-old with a history of extreme prematurity reveals baseline-predominant panlobular emphysema-like changes, bronchiectasis, bronchial wall thickening, and centrilobular tree-in-bud nodularity. Expiratory CT images demonstrate mosaic attenuation and air trapping, consistent with superimposed small airways obstruction.
Key takeaways
Bronchopulmonary dysplasia (BPD) is a chronic lung disease of prematurity that can result in persistent respiratory issues in adulthood. Adult survivors of BPD often show emphysema-like lung destruction (panlobular in appearance but not related to alpha-1 antitrypsin deficiency), bronchiectasis, and signs of constrictive or obliterative bronchiolitis resulting in air trapping.
