Summary
Infectious bronchiolitis, as a sole component or more frequently as a constellation of histologic findings related to diseases of more proximal airways or alveolated parenchyma, can be caused by respiratory syncytial virus (RSV), Mycoplasma pneumoniae, Chlamydia pneumoniae, Streptococcus pneumoniae, Hemophilus influenzae, tuberculous and nontuberculous mycobacterial organisms, and Aspergillus species. Infectious bronchiolitis and diffuse aspiration bronchiolitis (DAB) most commonly appear on high-resolution CT (HRCT) scans as centrilobular nodules and branching linear structures in the secondary pulmonary lobules or areas of air trapping.
