CTICasesBronchopulmonary Dysplasia Sequelae
Imaging findings
CT chest in a 20-something-year-old survivor of premature birth shows severe tracheal stenosis, tracheomalacia, marked pulmonary hyperinflation, and diffuse small airway abnormality with mosaic perfusion and air trapping, without significant parenchymal scarring.
Key takeaways
Bronchopulmonary dysplasia (BPD) is an acquired lung injury resulting from neonatal mechanical ventilation and oxygen toxicity in premature infants. Survivors who reach adulthood can present with chronic small airway disease, tracheomalacia, and severe tracheal stenosis rather than dominant pulmonary scarring, mimicking congenital airway syndromes.
