Metastatic pulmonary calcification in patients on long-term dialysis

Abstract

A 72-year-old woman was on dialysis for 44 years. Chest radiography revealed hazy opacity in the upper lung field (Figure 1A). Chest computed tomography (CT) showed patchy ground-glass opacities and fusion with overt calcification (Figure 1B). She had mild hypoxemia and impaired diffusing capacity. 99mTc-HMDP scintigraphy showed a prominent uptake in the lung fields corresponding to the patchy opacities (Figure 1C), indicating the accumulation of calcium in the lung parenchyma.
