TECHNETIUM-99M-METHOXYISOBUTYLISONITRILE IN LOCALIZATION OF ECTOPIC PARATHYROID ADENOMA

Preoperative localization of ectopic parathyroid lesions is crucial fo r the correct treatment of patients with primary hyperparathyroidism. Invasive and noninvasive procedures, including selective venography, u ltrasound, CT and MRI provide limited sensitivity in the detection of ectopic lesions. We report three patients in whom Tc-99m-MIBI scintigr aphy accurately detected ectopic parathyroid adenomas and was instrume ntal in the cure for these patients. Technetium-99m-MIBI scintigraphy provides a simple and accurate noninvasive test for the detection of e ctopic parathyroid adenomas.
