OBJECTIVE We aimed to compare the diagnostic accuracy of 18F-Fluorocholine (FCH)-positron emission tomography/computed tomography (PET/CT) and four-dimensional (4D)- CT in detection and localization of eutopic and ectopic parathyroid adenoma (PA) in patients with hyperparathyroidism. MATERIALS AND METHODS Five patients with primary hyperparathyroidism underwent FCH-PET/CT after 60 min of 185 ...

Localization of Tc-99m sestamibi (MIBI) by parathyroid adenomas (PA) is well known. Typically the radionuclide washes out slowly from the PAs located in the neck. Rapid washout from some PAs has been reported. Various hypotheses have been postulated for slow and rapid clearance of MIBI from PAs, located in the neck. However, the washout of MIBI from ectopic parathyroid adenoma (EPA) in not well...

OBJECTIVE To assess the efficacy of intraoperative parathyroid hormone (PTH) monitoring in evaluating the outcome of parathyroidectomy in pediatric patients. METHODS Intraoperative PTH monitoring during parathyroidectomy was performed in five children (3M, 2F); three had parathyroid adenomas (single gland disease) and two had primary hyperplasia. One patient had undergone two previous surgica...

IntroductIon Ectopically located hyperfunctioning parathyroid gland(s) are responsible for approximately 6–16% of hyperparathyroidism cases, in which about 6% can be ascribed to ectopic growth in the mediastinal site.[1] Treatment of ectopic adenomas usually requires resection. There are various techniques to resect ectopic parathyroid glands, which are mainly depended on the ectopic gland’s lo...

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, nausea,...

A 72-year-old female was referred to our unit with a right sided hemothorax following biopsy of a paratracheal mass (Video 1). The patient was initially seen by her general practitioner for hypertension. Routine blood investigations revealed hypercalcemia, (calcium 2.00 mmol/L, adjusted calcium 3.02 mmol/L) and hypophosphatemia (phosphate 0.84 mmol/L). Parathyroid hormone (PTH) levels were sign...
