Metastatic pulmonary calcification after renal transplantation.
Metastatic pulmonary calcifications, unlike dystrophic calcifications, occur in the normal healthy lung. The radiological pattern is quite specific. The disease is commonly described in chronic renal failure with calcium disorders. The prognosis is totally unpredictable. In 1992, a 50 yr old man underwent a successful renal transplantation during the final stage of chronic renal failure. He subsequently developed asymptomatic diffuse nodular opacities, that were discovered in 1995. An open lung biopsy confirmed the diagnosis of metastatic pulmonary calcification. There was no calcium disorder in this patient. In contrast to the benign course of pulmonary calcification in most patients, some fulminant pulmonary calcifications complicating renal transplantation or hypercalcaemia have been described. Radiographic identification of such entities is important to permit correction of calcium disorders. Otherwise, the condition is a potentially progressive and fatal cause of respiratory failure.
