[Metastatic calcification detected on bone scintigraphy].
OBJECTIVE
To show the value of bone scintigraphy in the diagnosis of metastatic calcification in end-stage renal insufficiency.


METHODS
The authors present a fifty-one-year-old male with terminal renal insufficiency of hypertensive renovascular etiology, on hemodialysis for the last 10 years, referred for a bone scan because of osteoarticular complaints, and no other associated symptoms or findings on physical examination.


RESULTS
Whole body bone scintigraphy images (HMDP-99mTc, 925MBq), showed increased uptake in the lower half of both lungs, the stomach and renal parenchyma, compatible with metastatic calcification.


CONCLUSIONS
Bone scintigraphy, due to its high sensitivity, even in the detection of early changes, might be a useful instrument in the initial evaluation and follow-up of patients with high risk of developing metastatic calcification.
