Fixations extra-osseuses du 99mTc MDP dans le cas d’un cancer du sein métastatique à l’os

Abstract

AimTo report and discuss an unusual visceral uptake on bone scan in a case of breast cancer with bone metastases. Patient and methodsA 40-year-old woman, with untreated bilateral breast cancer was referred to our department for a bone scan. ResultsThe bone scan evidenced multiple metastases over the axial skeleton. Uncommonly, visceral uptake was noted associating diffuse bilateral lung uptake and intense myocardium, stomach and kidneys uptakes. Serum calcium level was high: 4.08 mmol/L (normal: 2.38–2.70 mmol/L). ConclusionThe incidental observation of metastasic calcifications on bone scan is often related to severe hypercalcemia. Such pattern should alert the physician on the existence and the severity of calcium metabolism disturbances that had not been suggested before.
