Abstract: The introduction of thin-section computed tomography (CT) has improved the diagnosis of bronchiolitis and contributed to establish bronchiolitis as an important part of pulmonary medicine. The histo¬pathologic groups of bronchiolitis include cellular bronchiolitis, diffuse panbronchiolitis, follicular bronchiolitis, respiratory bronchiolitis, pro¬liferative bronchiolitis, constrictive bronchiolitis, and mineral dust air¬way disease. Bronchiolitis can be readily identified and may lead to characteristic findings on thin-section CT. Various bronchiolitis ma¬nifests as one or a combination of 3 main patterns in thin-section CT: centrilobular nodules and branching densities, ground-glass attenuation and consolidation, and low attenuation and mosaic perfusion pattern.
