Bronchiolitis in Adult
Alerts and Notices
Synopsis
Bronchiolitis should be suspected in an adult of any age with insidious onset (weeks to months) of nonproductive cough and dyspnea. High-resolution CT scan (HRCT) is the radiographic study of choice for diagnosis, although lung biopsy may be required in some cases. Treatment options are usually aimed at controlling symptoms, and care is often coordinated with a pulmonologist.
Etiologies include bronchiolitis obliterans or bronchiolitis obliterans syndrome, constrictive bronchiolitis, proliferative bronchiolitis, and cellular bronchiolitis.
