Pulmonary Crohn's disease: A rare extra-intestinal manifestation treated with infliximab

Abstract

Crohn's disease is a chronic inflammatory bowel disease often presenting with extra-intestinal manifestations. However, pulmonary involvement is quite rare. We report a case of Crohn's disease with pulmonary extra-intestinal manifestation (bronchiolitis obliterans organizing pneumonia-like changes) treated with infliximab. Furthermore, we present an overview of cases of inflammatory bowel disease with lung involvement, treated with tumor necrosis factor-α antagonists. In this case, when infliximab was given, a significant resolution of the pulmonary changes was achieved.
