Synonyms
- Fibrotic bronchiolitis
- Obliterative bronchiolitis
- Bronchiolitis obliterans
Definitions
- Idiopathic constrictive bronchiolitis
- Nonspecific, irreversible process
- Concentric fibrosis anatomically located between bronchiolar epithelium and muscularis mucosa
- Affects terminal and respiratory bronchioles with resultant bronchiolar luminal narrowing &/or obliteration
- Little bronchiolar/peribronchiolar chronic inflammation, absence of granulation tissue polyps
- Diagnosis of exclusion: Exclusion of known causes of constrictive bronchiolitis
- Constrictive bronchiolitis is not to be confused with bronchiolitis obliterans organizing pneumonia, preferably referred to as organizing pneumonia or as cryptogenic organizing pneumonia if idiopathic
- Idiopathic constrictive bronchiolitis
