Abstract:
When mild asymptomatic hypercalcemia occurs in a patient with hyperthyroidism, it may or may not be due to concurrent hyperparathyroidism and at times only the control of the hyperthyroidism will resolve the problem. Moreover, the presence of hyperfunctioning thyroid nodules will interfere with Tl-201/Tc-99m pertechnetate parathyroid scintigraphy. Initial treatment of hyperthyroidism with I-131 in this situation controls hyperthyroidism and permits successful localization of parathyroid adenomas, which may then be excised--a result that was achieved in three cases.
