Abstract

Metastatic pulmonary calcification (MPC) is calcium deposition in normal pulmonary parenchyma due to abnormal calcium metabolism. We present a case report of rapid progression of MPC due to primary hyperparathyroidism with hypercalcemia and acute renal failure. CT demonstrated rapidly progressive high-attenuation consolidation predominately in the upper lung fields. Bone scan revealed bilateral diffuse lung uptake suggesting MPC. Rapid progression of MPC is rare and may be misdiagnosed as air-space disease. Bone scan is useful for diagnosis of MPC, particularly when CT finding is atypical.
