  		Figure 2. Patient 5.  Transverse thin-section CT scan in a 73-year-old man shows a mixed attenuation pattern, with low-attenuation areas (arrows) that suggest hyperinflated secondary lobules with centrilobular vessels among smaller secondary lobules that show ground-glass opacification.

  		Figure 4. Patient 6.  Transverse thin-section CT scan in a 33-year-old man shows evidence of fibrosis—namely, irregular interfaces, parenchymal bands (large arrow), and traction bronchiectasis (small arrow).

  		Figure 5. Patient 4.  Transverse thin-section CT scan in a 54-year-old man. Small subpleural cysts (arrows) are present in areas with evidence of fibrosis such as parenchymal bands and irregular interfaces. A small pneumothorax is also present.

  		Figure 6. Patient 6.  Transverse thin-section CT scan in a 33-year-old man. A 1.8-cm thick-walled subpleural cyst (large arrow) is present in the middle lobe anterior to the major fissure. Evidence of fibrosis (small arrows) is present in the anterior basal segment of the right lower lobe.
