A rare case and review of pulmonary ossification

Abstract

Pulmonary ossification (PO) is a rare metastatic disease characterized by the formation of diffuse heterotopic bone units in the lung parenchyma. Herein, we describe a 45-year-old Filipino male with dendriform pulmonary ossification in combination with gastroesophageal reflux disease and chronic dust exposure, a notably unique association. Radiographic imaging and pathology findings are examined with discussion of various pulmonary disease entities from current literature. Further recognition of PO will facilitate appropriate treatment and better outcomes for patients diagnosed with this enigmatic condition.
