Crohn's disease (CD) is a chronic inflammatory disorder with an unknown etiology that commonly involves the gastrointestinal tract, and bronchopulmonary manifestations only occur in 0.4% of cases. There have not been any reports about pulmonary involvement in pediatric CD patients. We experienced a 14‐year‐old boy with Crohn's disease diagnosed with organizing pneumonia by chest CT‐guided biopsy examination. His pneumonia was intractable despite the administration of multiple antibiotics, and steroid therapy was very effective. In pediatric patients with CD whose lung disease does not respond to antibiotics, OP should be considered as a possible diagnosis.
