Chest computed tomography scan on admission. a) Diffusely scattered centrilobular fine nodular densities associated with emphysematous low attenuation areas in both apexes. b) Increased diffuse ground-glass opacities adjacent to peripheral air space consolidation in the right upper lung field.

Microscopic evaluation of the video-assisted thoracic surgery biopsied lung specimen from the posterior segment of the right upper lobe. a) A proliferative peribronchial fibrosis with cholesterol clefts in the centrilobular region. b) Numerous cholesterol clefts in the interstitium and intra-alveolar spaces. c) Alveolitis associated with intra-alveolar accumulation of alveolar macrophages containing brown particles and cholesterol clefts. d) Magnified view of the intra-alveolar macrophages. Haematoxylin and eosin stain was used. Scale bars: a) 0.5 mm, b) 0.25 mm, c) 25 µm, d) 10 µm.

Microanalysis of the biopsied lung specimen. a) Alveolitis with intra-alveolar accumulation of alveolar macrophages and numerous cholesterol clefts (haematoxylin and eosin stain). Scale bar = 0.5 mm. b) Electron probe X-ray microanalysis of a). The scattered small, white particles represent indium. c) Field emission-scanning electron microscopy and energy dispersive X-ray analytical spectrometer studies on the lung tissues. Three peaks of indium are indicated by arrows.
