Metastatic Pulmonary Calcification in a Patient with End-Stage Renal Disease and Hyperparathyroidism: A Case Report

Metastatic pulmonary calcification (MPC) is an occasionally encountered complication of uremia and a disordered calcium metabolism. Chest radiograph has limited effectiveness in the detection of MPC. Chest computed tomography (CT) scan, particularly high-resolution CT (HRCT), and bone scintigraphy are the preferred methods for detecting small amounts of calcification and diagnosing MPC, obviating the need for open lung biopsy. We report the case of a 58-year-old patient with uremia and secondary hyperparathyroidism who was diagnosed as having metastatic calcification, based on the history, chest x-ray, chest CT, and bone scintigraphy.
