Imaging findings
Chest radiograph showed dense calcification of both lung hila. CT demonstrated confluent, conglomerate centrilobular calcified nodules, predominantly in the upper lobes, in a patient with renal failure.
Key takeaways
Metastatic pulmonary calcification occurs in the setting of renal disease due to pH differences in the lung parenchyma, leading to precipitation of calcium ions, typically starting in the upper lobes.
