The key role of 99mTc-MIBI SPECT/CT in the diagnosis of parathyroid adenoma: a case report

The concomitant occurrence of primary hyperparathyroidism (PHPT) due to parathyroid adenoma and papillary thyroid carcinoma (PTC) is not common. The co-occurrence of parathyroid tumors and thyroid diseases can lead to misdiagnosis owing to mutual interference of imaging in the early period of disease. The most commonly used imaging techniques for the preoperative localization of parathyroid and thyroid adenomas are technetium-99m sestamibi (99mTc-MIBI) scintigraphy and ultrasonography of the neck. Recently, 99mTc-MIBI single-photon emission computed tomography associated with computed tomograp...
