Definition / general
  • Vast majority of patients with lung disease have history of IBD in GI tract, but lung disease may occur without GI disease
  • Lung involvement more common with ulcerative colitis than Crohn's disease
  • Acute or chronic bronchiolitis with nonnecrotizing granulomas, bronchopneumonia, interstitial pneumonia and organizing pneumonia
  • May be due to mesalamine (anti-inflammatory component of sulfasalazine, used to treat IBD)
  • May have CMV or atypical mycobacteria infections
