- Etiology: barotrauma from mechanical ventilation in patients with respiratory distress syndrome causes rupture of overdistended pulmonary alveoli leading to entry of air into pulmonary interstitium
- Imaging: air in pulmonary interstitium
- 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
