{{Hamman-Rich syndrom Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]; Associate Editor(s)-in-Chief: Chandrakala Yannam, MD [2]

Overview

Most of the patients with acute interstitial pneumonitis on HRCT will show bilateral ground-glass attenuation, traction bronchiectasis, airspace consolidation, architectural distortion. This pattern of abnormality is typically found in acute interstitial pneumonitis but it is not diagnostic.

CT scan

The high-resolution computed tomographic scan(HRCT) findings of acute interstitial pneumonitis include:^[1]^[2]^[3]
Bilateral, patchy, symmetric ground-glass attenuation
Bilateral airspace consolidation
- These findings can be seen in other diseases and are therefore nonspecific.
Traction bronchiectasis
Septal thickening
Honeycombing indicate the presence of underlying fibrotic lung disease.
