title: [Metastatic calcification detected on bone scintigraphy].
abstract: 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.
