A Renal Transplant Seen on Dual Photon Absorptiometry

摘要

A 25-year-old man who had a chronic rejection of renal transplantation performed 4 years earlier developed secondary hyperparathyroidism. Dual-photon absorptiometry of the lumbar spine and right femur were performed to evaluate changes in bone mass. A roundish highdensity area was seen in the right iliac region. Radiographs revealed that this corresponded to the renal transplant that had calcified. Clinical and radiographic correlation is necessary to evaluate some images seen on bone densitometry.
