Parathyroid carcinoma is a rare neuroendocrine tumor, responsible for less than 1% of all cases of primary hyperparathyroidism. The sole curative treatment is complete surgical removal and thus, an accurate preoperative diagnosis is necessary. Due to the rarity of this disease, there is no staging guidelines. Imaging of parathyroid glands is usually obtained with ultrasonography, computed tomography, scintigraphy and positron emission tomography. These imaging modalities have ...

Ectopic parathyroid tissue remains a significant hurdle in the surgical management of hyperparathyroidism. In diagnostically challenging cases of persistent hyperparathyroidism, unusual ectopic locations of parathyroid adenomas must be considered in order to avoid numerous re-operative explorations and the associated risks to the patient. We present a 30-year-old female was referred to the endocrinology department for symptomatic hypercalcemia. Routine laboratory investigation...

Objectives: The aim of this prospective study was to compare the diagnostic performance of 99mTc-sestaMIBI SPECT scintigraphy (sestaMIBI), 18F-fluorocholine PET/CT or PET/MR (FCH) for preoperative localization of hyperfunctioning parathyroid gland.Materials and Methods: 60 patients with biochemical evidence of primary (n=57) or tertiary (n=3 kidney transplanted patients) hyperparathyroidism were imaged prospectivel...
