Patient Data

Low lung volume with bi-basilar dependent atelectasis/consolidation.
Bi-basilar and dependent ground glass opacities, interlobular septal thickening and mild traction broncheiactasis.
6 month follow up
There is progression of the bi-basilar traction broncheactasis and parenchymal architectural distortion of the lung bases.
One year from initial chest xray

Persistent low lung volume with bi-basilar atelectasis/scarring.
Another 6 month follow up
Persistent, essentially stable, bi-basilar traction broncheiactasis and architectural distortion.
Case Discussion
This case demonstrates the typical findings of acute interstitial pneumonitis (AIP), considered a rapidly progressive interstitial disease of unknown etiology.
The disease suspicion confirmed by open lung biopsy; which demonstrates the combination of diffuse alveolar damage (DAD) along with some changes of cryptogenic organizing pneumonia (COP).
