(Panel D) Chest radiograph of a 67-year-old man, showing extensive bilateral disease, with diffuse alveolar space densities, opacification, reticulonodular opacities, and bronchial wall thickening.
(Panel E) Chest radiograph of a 49-year-old man, showing extensive bilateral mid and lower zone disease, with diffuse reticulonodular alveolar space opacities. A thoracic computed tomography scan in the same patient (Panel F) shows extensive bilateral opacities and ground-glass reticulonodular shadowing and bronchiolar wall thickening.
