lobar hyperinflation

Digital cases

 HPC:390 : Five cases of congenital lobar hyperinflation (or congenital lobar emphysema)
 HPC:422 : Congenital lobar hyperinflation (or congenital lobar emphysema)

Definition: Lobar hyperinflation in the neonate is usually congenital, resulting from cartilage deficiency causing bronchomalacia and distal air trapping.

The congenital lobar hyperinflation (or congenital lobar emphysema) is the most frequent fetal/neonatal pulmonary anomaly, before congenital pulmonary airway malformations (CPAMs).

An acquired lobar hyperinflation is usually associated with chronic lung disease or endobronchial obstruction such as mucus plugging or a pedunculated endobronchial polyp. (17206431)
