The diagnosis of hyperparathyroidism rests on clinical and biochemical laboratory criteria. Once the diagnosis is established, it is the function of diagnostic imaging to pre-operatively find the suspected parathyroid adenoma. Traditionally, nuclear medicine techniques such as 99mTc-Sestamibi scan and ultrasound evaluation have been the mainstay in finding the neoplasm. However, results are not...

A 57-year-old man presented with persistent hyperparathyroidism following primary parathyroidectomy. A four-dimensional computed tomography scan with three-dimensional reconstruction showed two parathyroid glands (one right and one left) and anatomic variation from previous surgery. Revision surgery was performed revealing the parathyroid glands as expected from the preoperative three-dimension...

We compared F-fluorocholine hybrid positron emission tomography/X-ray computed tomography (FCH-PET/CT) with ultrasonography (US) and scintigraphy in patients with hyperparathyroidism and discordant, or equivocal results of US and I/Tc-sesta-methoxyisobutylisonitrile (sestaMIBI) dual-phase parathyroid scintigraphy. FCH-PET/CT was performed in 17 patients with primary (n1⁄4 11) lithium induced (n...

UNLABELLED Haemorrhage of a parathyroid adenoma is a rare clinical presentation. This report describes a previously fit and well 54-year-old woman who presented with acute neck swelling and pain with an overlying ecchymosis. Admission laboratory tests revealed a raised parathyroid hormone and hypercalcaemia. A computed tomography (CT) scan showed widespread anterior cervical haemorrhage and a l...

In thyroid and parathyroid surgery, surgical energy devices (SEDs) provide more efficient hemostasis than conventional clamp-and-tie in areas with rich blood supply. However, when a SED is activated near the recurrent laryngeal nerve (RLN), heat generated by may injure irreversibly. To safely apply SEDs thyroid/parathyroid this article introduces experimental porcine model studies to investigat...

BACKGROUND The most common radionuclide procedures for parathyroid imaging are (99m)Tc-MIBI/ (99m)Tc pertechnetate subtraction scintigraphy and (99m)Tc-MIBI double-phase imaging, with estimation of MIBI wash-out rate. Those two methods are by some authors regarded as complementary techniques, yielding the best evaluation of parathyroid gland if performed conjointly. By such an approach it seems...

Paget´s disease of bone is a disorder characterized by disorganized remodeling. It´s occurrence in patients with end-stage kidney on renal replacement therapy rare. Here we report case an 80-year-old male peritoneal dialysis that presented high level alkaline-phosphatase mildly elevated parathyroid hormone and typical imaging findings localized to the pelvis. This fourth reported patient first ...

abstract parathyroid adenoma is a benign tumor of the parathyroid glands. the cause of most parathyroid adenomas is unknown. parathyroid adenoma increases the secretion of parathyroid hormone and results in primary hyperparathyroidism. high amounts of parathyroid hormone in the blood cause the imbalance of calcium, which leads to various complications such as kidney stones, depression, lethargy...

OBJECTIVE This study aims to compare the sensitivity of dual phase (non-contrast and arterial) versus single phase (arterial) CT for detection of hyper-functioning parathyroid glands in patients with primary hyperparathyroidism. METHODS The CT scans of thirty-two patients who have biochemical evidence of primary hyperparathyroidism, pathologically proven parathyroid adenomas, and pre-operativ...
