Obliterative bronchiolitis after bone marrow transplantation in a 47-year-old man with myeloma. (a) Expiratory high-resolution CT scan shows diffuse centrilobular nodules connected to branching linear opacities bilaterally. Note the air trapping in the right lower lobe. (b) Photomicrograph (original magnification, ×200; hematoxylin-eosin stain) of a specimen from open lung biopsy shows the bronchiolar walls surrounded by concentric chronic inflammatory infiltrates (arrows).
