This study aimed to describe the structural pulmonary sequelae of bronchopulmonary dysplasia (BPD) in adulthood. Subjects and methods: Fifty‐one adult survivors (36 females and 15 males; median age 20 years) of BPD underwent high‐resolution inspiratory and expiratory computed tomography of the chest. The scans were evaluated independently by two thoracic radiologists blinded to the patient's clinical details using a standardised scoring system. Results: Abnormal findings were seen in 50 (98%), the most common of which were subpleural triangular opacities (94%), linear opacities (90%), air trapping (65%) and emphysema (47%). The kappa values were derived by simplifying the score for each finding as present or absent. The kappa values for these findings were 0.65, 0.20, 0.58 and 0.54, respectively. Conclusions: Common findings were triangular, linear opacities and gas trapping. Emphysema diagnosis was more prevalent than previous studies, which may have been enhanced by improved technical factors.
