We report the computed tomography findings of five patients with pathology proven pulmonary amyloidosis. Tracheobronchial amyloidosis with calcified nodules and plaques in the tracheal wall were seen in two patients. Two other patients had diffuse parenchymal disease with calcified lesions, one had reticular and nodular subpleural opacities whereas the other had nodular interlobular septal thickening and a parenchymal consolidation. The latter presented the nodular type of the disease with multiple sharp nodules scattered throughout the lungs and interspersed calcifications. The computed tomography findings observed were not specific but strongly suggestive of amyloidosis.

We report the findings of the high-resolution computed tomography of the chest of a patient with pulmonary talcosis related to intravenous injection of diluted oral medicine. The most important high-resolution computed tomography findings were small centrilobular nodules associated with conglomerated masses. Areas of emphysema and ground glass attenuation were also seen. These high-resolution computed tomography findings are highly suggestive of pulmonary talcosis.

The authors report the high-resolution computed tomography findings of three sandblaster patients with acute silicosis. High-resolution computed tomography showed air space disease in all patients, with consolidation, air bronchogram, and parenchymal calcifications. Centrilobular ground-glass nodules, generally confluent, as well as calcified mediastinal and/or hilar nodes and enlarged lymph nodes were also seen in all patients.
