Differential diagnoses include dystrophic calcifications, metastatic calcifications, and pulmonary alveolar microlithiasis. Dystrophic calcifications occur in diseased lung, in the setting of granulomatous infections, sarcoidosis, occupational lung diseases and metabolic diseases (eg, as amyloidosis). Metastatic calcifications occur in normal lung due to hypercalcemia secondary to end-stage kidney disease. The differential diagnosis also includes nodular ossification seen in patients with chronic venous lung congestion (8) . The absence of any relevant past medical history, concomitant diseases, normal renal function and phosphate calcium homeostasis excluded other causes of lung calcification/ossification in this case.
