High-resolution chest computed tomography of the lungs. Metastatic pulmonary calcification: A) axial scan of the upper lungs shows bilateral, symmetrical, diffuse, indistinct, centrilobular ground-glass opacities with sparing of the periphery of the lobule and interlobular septa, B) coronal reformation shows predominantly upper and middle lung distribution of opacities

HRCT showed bilateral, diffuse, centrilobular ground-glass opacities and heterogeneous high-density areas distributed throughout the lungs, predominantly in the upper and middle lobes, with no apparent thickening of the interlobular septa, hilar, or mediastinal lymph node enlargement (Fig. 1). HRCT also showed vessel calcifications in the wall of the chest (Fig. 2B) and bronchial calcifications (Fig. 2A).
High-resolution chest computed tomography of the lungs. Accompanying findings of metastatic pulmonary calcification: (A) coronal reformation shows calcifications (arrows) in the walls of the trachea and bronchi, (B) axial scan shows calcifications (arrow) in a vessel of the chest wall

Follow-up computed tomography (CT) examinations. Slight progression of diffuse, centrilobular ground-glass opacities is visible bilaterally in the lower parts of the lungs due to metastatic pulmonary calcification, assessed retrospectively - (A) baseline CT, (B) follow-up CT after 1 year, (C) follow-up high-resolution chest computed tomography after 2 years (arrows show progression of metastases of renal carcinoma, *diaphragm)
