Pulmonary calcinosis following orthotopic liver transplantation.
Pulmonary opacities following orthotopic liver transplantation (OLT) are frequent due to pneumonia, infarction, or pulmonary edema. Metastatic pulmonary calcifications are present as persistent opacities that may mimic these conditions. In a series of 91 patients who underwent OLT, chest radiographs of 77 were reviewed and pulmonary calcinosis was seen in 4 (5.2%). Pulmonary calcinosis may be due to a variety of conditions, including dystrophic calcification in damaged lung and primary or secondary hyperparathyroidism. In this series, patients with pulmonary calcinosis had significantly higher levels of serum phosphate and calcium postoperatively and had received more intraoperative platelets and other blood products containing exogenous calcium than other patients. Pulmonary calcinosis should be considered in patients following OLT when stable, nonspecific pulmonary opacities are present. CT or radionuclide studies will aid in confirming this diagnosis.
