Metastatic pulmonary calcification in a patient with a functioning kidney allograft. Report of one case

In renal transplants patients, metastatic pulmonary calcifications have been reported occasionally when the grafts are dysfunctional and rarely when they are functioning normally. We report a male who received a renal allograft in 1994 at the age of 61 years. Nineteen years later a routine chest X ray showed diffuse infiltrates and a CT scan showed diffuse calcifications in both lungs. These were interpreted as metastatic pulmonary calcifications. The last available laboratory determinations were a serum creatinine of 1.4 mg/dl and urinary protein excretion of 255 mg/24 hours. No further studies were done since the patient experienced a sudden death due to an acute myocardial infarction.
