O. Geattl et al., CONCURRENT PLUMMERS-DISEASE AND PARATHYROID ADENOMA - DIAGNOSTIC AND THERAPEUTIC APPROACHES TO A DIFFICULT CLINICAL PROBLEM, Clinical nuclear medicine, 19(6), 1994, pp. 508-511
When mild asymptomatic hypercalcemia occurs in a patient with hyperthy
roidism, it may or may not be due to concurrent hyperparathyroidism an
d at times only the control of the hyperthyroidism will resolve the pr
oblem. 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 cont
rols hyperthyroidism and permits successful localization of parathyroi
d adenomas, which may then be excised-a result that was achieved in th
ree cases.
