UNLABELLED Parathyroid cysts are rare (0.8-3.41% of all parathyroid lesions) and usually arise secondary to cystic degeneration of parathyroid adenomas. Intrathyroidal parathyroid cysts are extremely rare with only three cases reported till date. We present a 24-year-old female with clinical and biochemical features of primary hyperparathyroidism (PHPT; Ca(2) (+): 12.1 mg/dl; intact parathyroid...
We report a rare case of distant subcutaneous parathyroid carcinoma recurrence. A 50-year-old woman was referred to our hospital because of sustained hypercalcemia despite surgical removal of a parathyroid carcinoma. A focal uptake in the upper mediastinal area was detected in a (99m)Tc-sestamibi scan, and (18)F-fluorodeoxyglucose (FDG) positron-emission tomography (PET)/computed tomography (CT...
Background Selective venous sampling (SVS) is an invasive localization study for persistent or recurrent hyperparathyroidism. Purpose To assess the role of SVS in addition to non-invasive imaging for primary hyperparathyroidism (pHPT). Material and Methods This study was approved by the institutional review board and included 14 patients who underwent SVS and subsequent parathyroidectomy be...
We report a case of severe hyperparathyroidism complicated by osteitis fibrosa cystica in an 83-year-old man post-myocardial infarction. The lesions were evident on magnetic resonance imaging only. A diagnosis of parathyroid carcinoma was considered due to clinical appearance of the parathyroid intraoperatively and the presence of an invasive T3 lesion mimicking metastatic disease. Differentiat...
OBJECTIVE The aim of this study was to further elucidate the mechanisms of dual-phase technetium-99m methoxyisobutylisonitrile (Tc-MIBI) parathyroid imaging by exploring the association between early uptake results (EUR), delayed uptake results (DUR), and the retention index (RI) in dual-phase Tc-MIBI parathyroid imaging and P glycoprotein (P-gp), multidrug resistance-associated protein 1 (MRP1...
We report a 52-year-old woman who was noted to have elevated alkaline phosphatase (ALP), hypercalcemia (Ca: 11.7 mg/dL), and intact parathyroid hormone (intact PTH: 643.1 pg/mL), and then referred to our hospital with suspected hyperparathyroidism. Ultrasound examination of the neck and magnetic resonance imaging showed a mass region in the posterior aspect of the left lobe of the thyroid, and ...
Clinical usefulness of intraoperative parathyroid hormone monitoring for primary hyperparathyroidism
Purpose The availability of intraoperative parathyroid hormone (IOPTH) monitoring allows successful focused parathyroidectomy for primary hyperparathyroidism (pHPT). The objective of this study was to report our initial experience in IOPTH monitoring during parathyroid surgery for primary hyperparathyroidsim. Methods Between May 2011 and February 2013, 37 patients underwent focused parathyroi...

AbstractParathyroid 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,...
Parathyroid carcinoma is a rare cause of primary hyperparathyroidism. Clinical indicators of carcinoma include the severity of hyperparathyroidism and presence of a palpable neck mass. Definitive diagnosis requires surgical resection and specimen histology, or documentation of metastatic disease. We present a case of parathyroid carcinoma in a young female patient with severe hyperparathyroidis...
