[Unusual course of renal osteopathy with Paget's disease and aluminum deposits].

In a woman with chronic renal failure due to interstitial nephritis after chronic analgesic abuse, secondary hyperparathyroidism was at first the predominant feature during a one-year period of dialysis. After parathyroidectomy severe aluminium-induced osteomalacia dominated the picture in the final phase. Surprisingly hyperparathyroidism recurred despite removal of all glandular tissue, and there also developed--previously undescribed--Paget's disease.
