[Radionuclide imaging of parathyroid adenoma using the 201TI-99mTc substraction scintigraphy method].
Primary hyperparathyroidism is the most frequent parathyroid disease. Parathyroid adenomas account for the majority of primary hyperparathyroidism (81%) while carcinoma and diffuse hyperplasia occur less frequently (4% and 15%). Ten per cent of adenomas are located substernally. The difficulties of preoperative localization of parathyroid adenomas may lead to incomplete surgical removal. Therefore an accurate technique for preoperative localization of the parathyroid gland is of utmost importance. Various imaging methods are available (ultrasonography, computer tomography, angiography, etc.), each with their own limitations. Thus, a nuclear technique performed via 201Tl-99mTc dual isotope subtraction scintigraphy may well contribute to the safety of diagnostics. The authors present a case of parathyroid adenoma diagnosed by this method and confirmed histologically. The role of non-invasive techniques in preoperative localization of parathyroid adenomas protecting the patient from invasive procedures and repeated surgical explorations is highly emphasized.
