HRCT may show multiple 3 to 10mm calcified nodules or, more commonly, fluffy nodular opacities that mimic air space nodules but that contain foci of calcification. A frequently associated finding is calcification involving the vessels of the chest wall.
Metastatic pulmonary calcification is associated with a variety of benign and malignant disorders such as
- primary and /or secondary hyperparathyroidism
- chronic renal failure
- intravenous calcium therapy
- multiple myeloma
- massive osteolysis caused by metastases.
