Fig. 7A 56-year-old man with chronic hypersensitivity pneumonitis due to
occupational exposure to isocyanate compounds in paint. High-resolution CT
scan shows bilateral reticulation, traction bronchiectasis (curved
arrow), and traction bronchiolectasis (straight arrows). Also
evident are subpleural cysts consistent with mild honeycombing
(arrowheads). Area of ground-glass opacity with superimposed
reticulation is present in right middle lobe. These high-resolution CT
findings resemble those of nonspecific interstitial pneumonia.
