Metastatic pulmonary calcification: high-resolution computed tomography findings in 23 cases

Figures

• 

  Figure 1. 37-year-old woman with biopsy-proven metastatic pulmonary calcification due to end-stage renal disease. A: HRCT at the level of the upper lobes shows bilateral ill-defined centrilobular ground-glass nodular opacities, with confluence. B: Image obtained at the level of the lower lobes shows similar, but less extensive, findings.

• 

  Figure 2. 67-year-old man with biopsy-proven idiopathic metastatic pulmonary calcification. HRCT at the level of the upper lobes shows bilateral ill-defined centri-lobular ground-glass nodules. Mediastinal window (not shown) demonstrated punctiform calcification in some nodules and diffuse calcification in others.

• 

  Figure 3. 40-year-old woman with biopsy-proven metastatic pulmonary calcification. A: HRCT at the level of the lower lobes shows diffuse bilateral ground-glass opacities and dense consolidation in the posterior right lower lobe. B: Image obtained at the same level with mediastinal window settings demonstrates calcification within the area of consolidation, as well as scattered punctate foci of calcification. Note also small bilateral pleural effusion.

• 

  Figure 4. 89-year-old man with biopsy-proven metastatic pulmonary calcification due to end-stage renal disease. A: Axial image obtained with mediastinal window settings at the level of the lower lobes shows multiple small, dense, subpleural nodules. B: Sagittal image obtained with mediastinal window settings demonstrates the peripheral distribution of the nodules, in a subpleural location and adjacent to the fissures.

• 

  Figure 5. 85-year-old man with biopsy-proven metastatic pulmonary calcification due to end-stage renal disease. A: HRCT at the level of the lower lobes shows multiple small, dense, peripheral nodules associated with reticular opacities. B: Image obtained at the same level with mediastinal window settings shows scattered foci of calcification along the nodules.

  Figure 6. 55-year-old man with biopsy-proven metastatic pulmonary calcification due to end-stage renal disease. A: Axial maximum intensity projection (MIP) image demonstrates calcification along the vessels of the chest wall (arrows). B: Coronal MIP image shows calcification along the coronary and abdominal arteries, and in the vessels of the chest wall (arrows).
