# A Case of Metastatic Pulmonary Calcification **Authors:** Diane Lefebvre, Pascale Bohy PMC · DOI: 10.5334/jbsr.4210 · 2026-03-03 ## TL;DR The paper discusses a case of metastatic pulmonary calcification, explaining its causes and radiographic features. ## Contribution It highlights the distinction between metastatic and dystrophic calcification through a case study and radiographic analysis. ## Key findings - Metastatic calcification is linked to metabolic imbalances and has distinct CT features. - Accurate diagnosis relies on recognizing specific radiographic patterns. ## Abstract Pulmonary calcifications are a frequent phenomenon with a wide range of etiology. They are divided into two categories: metastatic and dystrophic pulmonary calcification, with different underlying pathology and CT features. Teaching point: Metastatic pulmonary calcifications appear when there is a metabolic imbalance with some typical radiographic features for characterization. ## Full-text entities - **Diseases:** encephalopathy (MESH:D001927), rheumatoid arthritis (MESH:D001172), metastasis (MESH:D009362), atelectasis (MESH:D001261), co-infection (MESH:D060085), hemorrhagic shock (MESH:D012771), hypercalcemia (MESH:D006934), thrombocytopenia (MESH:D013921), sarcoidosis (MESH:D012507), infection (MESH:D007239), tuberculosis (MESH:D014376), cardiac ventricle (MESH:D006331), ILD (MESH:D017563), amyloidosis (MESH:D000686), chronic pulmonary disease (MESH:D002908), silicosis (MESH:D012829), hyperphosphatemia (MESH:D054559), chondroma (MESH:D002812), hepatocellular carcinoma (MESH:D006528), protein deposition disease (MESH:D000079822), hyperparathyroidism (MESH:D006961), cirrhosis (MESH:D005355), dysmetabolism (MESH:D024821), hamartoma (MESH:D006222), porcelain heart (MESH:C535889), neoplastic disease (MESH:D004194), inflammatory disease (MESH:D007249), DPC (MESH:D000092182), Pulmonary (MESH:D008171), Calcification (MESH:D002114), benign neoplasms (MESH:D009369), renal failure (MESH:D051437), acute tubular necrosis (MESH:D007683), pneumonia (MESH:D011014), COPD (MESH:D029424), autoimmune disease (MESH:D001327), ischemic cholangitis (MESH:D002761), histoplasmosis (MESH:D006660), neuroendocrine pulmonary tumor (MESH:D018358) - **Chemicals:** calcium (MESH:D002118), phosphate (MESH:D010710), vitamin D (MESH:D014807) - **Species:** Homo sapiens (human, species) [taxon 9606] ## Figures 3 figures with captions in the complete paper: https://tomesphere.com/paper/PMC12962241/full.md --- Source: https://tomesphere.com/paper/PMC12962241
