An open lung biopsy performed 5 days after a previously healthy young man with hemoptysis was intubated showed bronchiolitis obliterans organizing pneumonia, characterized by granulation tissue in the bronchiolar lumen, alveolar ducts, and some alveoli. Chest radiographs typically show bilateral patchy alveolar infiltrates and nodules. Lung biopsy via video-assisted thoracoscopic surgery is preferred for diagnosis.
