TUMORAL CALCINOSIS-LIKE METASTATIC CALCIFICATION IN A PATIENT WITH RENAL OSTEODYSTROPHY - CT AND SCINTIGRAPHIC APPEARANCES

Hyperparathyroidism and renal osteodystrophy are the disorders usually associated with metastatic calcifications, including tumoral-calcinosis-like calcification in soft tissue in dialysis patients. Tumoral calcinosis is a hard, juxta-articular mass comprised of septal, thick connective tissue and cavities filled with a dense milky substance. The authors report plain radiographic, CT, and scintigraphic findings of a large tumoral-calcinosis- like metastatic calcification accompanying renal osteodystrophy in a renal dialysis patient. This rare form of metastatic calcification and renal osteodystrophy as a background condition were demonstrated on bone imaging.
