CTICasesAdult Bronchopulmonary Dysplasia
Imaging findings
CT chest in an adult shows diffuse mosaic attenuation, severe regional air trapping on expiration, and pulmonary vascular rarefaction (thin, scrawny vessels in hyperlucent zones). The patient had a history of extreme prematurity and neonatal mechanical ventilation.
Key takeaways
Surviving adults with neonatal bronchopulmonary dysplasia (BPD) demonstrate a characteristic pattern of mosaic perfusion, vascular attenuation, and air trapping on CT. This pattern is easily confused with Swyer-James syndrome or severe asthma, and requires checking pediatric history to establish the diagnosis.
