Case Discussion

Thoracic manifestations in Crohn disease are rare, usually due to infection and may precede the intestinal manifestations. The pathogenesis of pulmonary involvement may be related to its common embryonic origin with the intestinal system from the primitive foregut. 

The respiratory manifestations may include:

  • bronchiectasis
  • chronic bronchitis
  • interstitial lung disease
  • cryptogenic organizing pneumonia
  • necrobiotic nodules
