[CT imaging features of bronchiolitis].

Abstract
Bronchiolitis may be encountered in numerous clinical circumstances. Previous history of smoking, infections, toxic exposure, immunodeficiency, chronic inflammatory disorders or transplantation must be known. CT findings consist in centrilobular micronodules with sharp or ill borders of various density and/or a mosaic attenuation with expiratory air trapping. Tree-in-bud pattern suggest an inflammatory or infectious bronchiolitis. The associated presence of bronchiectasis and bronchiolectasis must be considered. Imaging-pathologic correlations will be presented for inflammatory bronchiolitis (infectious bronchiolitis, hypersensitivity pneumonitis, respiratory bronchiolitis, follicular bronchiolitis, diffuse panbronchiolitis) and fibrosing bronchiolitis (constrictive bronchiolitis, post-infectious bronchiolitis, toxic fume exposure, transplant-related bronchiolitis).
