CTICasesAdult Bronchopulmonary Dysplasia
Imaging findings
CT chest in a young adult shows bilateral, patchy regions of severe air trapping, regional lucencies, and marked pulmonary vascular attenuation. The main pulmonary artery and right heart chambers are dilated, consistent with secondary pulmonary hypertension.
Key takeaways
Bronchopulmonary dysplasia (BPD) is a chronic lung disease of prematurity. In young adults who survive BPD, the disease manifests as chronic, severe air trapping, architectural distortion, and pulmonary hypertension due to restricted vascular bed development, rather than the coarse scarring typical of older patient cohorts.
