Diffuse pulmonary ossification detected by bone scanning with Tc-99m hydroxymethylene diphosphate.
Diffuse pulmonary ossification (DPO) is a rare pathologic finding of heterotropic bone formation within the lungs. It has been associated with mitral stenosis, chronic left ventricular failure, interstitial fibrosis, metastatic breast cancer, pulmonary amyloidosis, histoplasmosis, and chronic busulfan therapy. This patient represents a case associated with Placidyl use.
