Hamman-Rich syndrome CT
Introduction
Overview
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
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.
