Bronchopulmonary Dysplasia
Etiology: lung disease caused by preterm birth and lung development in extrauterine environment, premature infants with respiratory distress syndrome who are chronically ventilated for more than 30 days
Imaging: hyperexpanded lungs due to emphysematous blebs with interstitial scarrng, CXR findings normalize over very long-term, CT findings never normalize
Clinical: is the more severe phenotype of a continuum of lung disease caused by extrauterine development due to preterm birth, more severe clinical course than chronic lung disease
Cases of Bronchopulmonary Dysplasia
CXR AP+lateral shows bilaterally increased interstitial lung markings and increased lung volumes along with emphysematous blebs in the left upper, left lower and right lower lobes. Coronal CT without contrast of the lungs shows bilaterally increased interstitial lung markings and increased lung volumes along with an emphysematous bleb in the left lower lobe.
