From: Pulmonary interstitial emphysema in fatal asthma: case report and histopathological review
Post mortem computed tomography. High-resolution lung images show distended lungs with extensive bilateral air trapping, sometimes heterogeneous as pointed in *, associated with a decrease in vascularity. PIE dissects peribronchovascular interstitium in the right lower lobe, besides segmentary (a) and subsegmentary (b) bronchi. There is also bronchial wall thickening with associated narrowing of bronchial lumen.
