Media file 1: Chest radiograph in an 81-year-old woman with mitral- and aortic-valve stenosis, hiatal hernia, and iron-deficiency anemia of unknown cause. The patient had undergone right-sided mastectomy for a carcinoma of the breast 20 years earlier. She presented with migratory lung opacities and areas of consolidation. Radiograph shows areas of consolidation at the lung base, with an air bronchogram at the right lung base. A wedge-shaped, pleural-based opacity is demonstrated astride the lateral part of the lesser fissure.

The patient had undergone right-sided mastectomy for a carcinoma of the breast 20 years earlier. Radiograph obtained 2 months after Image above shows that the consolidation had moved to the right upper zone and both midzones.

Media file 4: Photomicrograph of a transbronchial biopsy sample of the right–upper-lobe bronchus of an 81-year-old woman with mitral- and aortic-valve stenosis, hiatal hernia, and iron-deficiency anemia of unknown cause (same patient as in Images above). The patient had undergone right-sided mastectomy for a carcinoma of the breast 20 years earlier. The slide was a part of a series of sections that showed granulation tissue polyps within the lumina of the bronchioles and alveolar ducts. These were associated with patchy areas of organizing pneumonia consisting largely of mononuclear cells and foamy macrophages in the surrounding lung. Plugs of immature fibroblasts covered by cuboidal cells were seen. There was a variable degree of infiltration of interstitium and alveoli.

Media file 5: A 54-year-old man with asthma and an 8- to 9-month history of left-sided chest pain, anorexia, weight loss, and increasing shortness of breath. The patient had an episode of pneumonia 6 months previously, when a chest radiograph showed a right-sided, apical, segmental consolidation, which improved with antimicrobial therapy. This radiograph shows opacity in the left upper zone, with tethering to the pleural space.
