  		Figure 1a: Images in a 26-year-old woman. (a) Transverse CT scan obtained 1 cm below the level of tracheal carina shows centrilobular nodules (arrows) in peripheral distribution. Ground-glass opacity is also present (arrowheads). (b) Photomicrograph of surgical biopsy specimen from right upper lobe shows infiltration of lymphocytes into respiratory bronchioles and alveolar walls (arrows). (Hematoxylin-eosin stain; original magnification, x100.)

  		Figure 2: Transverse CT scan in a 76-year-old woman obtained at the level of carina shows thickening of bronchovascular bundles (arrows) and presence of centrilobular nodules (tree-in-bud pattern) (arrowhead). Surgical biopsy specimen (not shown) from left upper lobe demonstrated lymphocytes infiltrating along bronchovascular bundles with mild fibrosis.

  		Figure 3: Transverse CT scan in a 72-year-old woman obtained at the level of right hemidiaphragm shows centrilobular nodules (black arrows), bronchiectasis (arrowheads), and bronchial wall thickening (white arrows). Surgical biopsy specimen (not shown) from right lower lobe demonstrated mild bronchiectasis and lymphocytes without any nuclear atypia infiltrating the walls of respiratory bronchioles and extending into the adjacent peribronchiolar interstitium.

  		Figure 5: Transverse CT scan in a 27-year-old woman obtained at the level of right hemidiaphragm shows centrilobular nodules (tree-in-bud pattern) (arrows) and mild thickening of bronchial wall (arrowheads). Surgical biopsy specimen (not shown) from right lower lobe demonstrated infiltration of lymphocytes along the bronchial wall.
