Metastatic pulmonary calcification

Metastatic pulmonary calcification (MPC) may develop in patients with secondary hyperparathyroidism, related to end-stage renal disease (ESRD).1 The histologic pulmonary findings show calcium deposition in the lung interstitium, alveolar septa and bronchial walls.2 We present a patient with CT findings of MPC that resolved with medical treatment for secondary hyperparathyroidism. To our knowledge, complete resolution of metastatic pulmonary calcification following treatment has not been previously described in the literature
