Absent kidney sign associated with symmetrical and uniformly increased uptake of radiopharmaceutical by the skeleton.

In 11 patients 99mTc-stannous H.E.D.P. bone scans showed absent renal images associated with symmetrical and uniformly increased uptake of radiopharmaceutical by the skeleton. These appearances are frequently seen in renal osteodystrophy but are uncommon in malignant disease. Their significance in hypervitaminosis D requires further evaluation.
