- Etiology: barotrauma from mechanical ventilation in patients with respiratory distress syndrome
- Imaging: see rupture of alveoli with air leaking into interstitium, lymphatics, venous system
- DDX: Pulmonary interstitial emphysema vs. airbronchograms of respiratory distress syndrome – both branch but pulmonary interstitial emphysema is thicker + blacker without orderly tapering of air bronchograms
- Complications: prelude to pneumothorax, often tension pneumothorax
