Abstract:
Hypercalcemia is a severe complication in cases of vitamin D intoxication that can result in metastatic calcification. We herein report a female case with hypercalcemia due to eldecalcitol administration associated with the increased uptake of technetium-99m hydroxymethylene diphosphonate (99mTc-HMDP) as the bone-scanning agent in the stomach. A histologic assessment using biopsy specimens identified metastatic calcification of the stomach. After the normalization of serum calcium levels, the gastric uptake of 99mTc-HMDP disappeared. This case indicates the usefulness of bone scintigraphy with 99mTc-HMDP to detect visceral metastatic calcification and to monitor its therapeutic effects in patients with hypercalcemia.
