F18-Choline, a Novel PET Tracer for Parathyroid Adenoma?

Parathyroid dual tracer subtraction scintigraphy: small regions method for quantitative assessment of parathyroid adenoma uptake.

OBJECTIVE The aim was quantitative assessment of parathyroid adenoma (PTA) uptake in dual tracer dynamic scintigraphy. METHODS In 78 patients, median age 58 (19-80) years, surgically treated for primary hyperparathyroidism (PHPT), with parathyroid hormone median 125 (70-658) pg/ml, we performed preoperative parathyroid scintigraphy, following EANM guidelines of subtraction and double-phase pr...

Parathyroid adenoma Localization

 Background: Bilateral neck exploration is the gold standard for parathyroid adenoma localization in primary hyperparathyroidism. But surgeons do not have adequate experience for accurate surgical exploration and new methods are developed for surgery like unilateral exploration and minimally invasive surgery, thus, preoperative localization could reduces time and stress in surgical performance....

Parathyroid adenoma mimicking cervical recurrence on CT/PET fusion scan.

The patient was treated with primary chemoradiation. Six months following the completion of treatment, he was found to have fullness of the right tonsillar fossa. A right tonsillectomy for biopsy purposes revealed squamous cell carcinoma. A composite resection of the right oropharynx with neck dissection and fibular free-flap reconstruction was performed. Metastatic lymph nodes were not found i...

unusual ectopic parathyroid adenoma: a case report

an ectopically placed parathyroid in the mediastinum is a rare cause of persistent or recurrent primary hyperparathyroidism. they are rarely in a huge size. we report a case of a 70-year-old man with a history of total parathyroidectomy and thymectomy presented with a lack of appetite, nausea, and generalized bone pain, polydipsia and a calcium level of 14.4 mg/dl. 99m tc-sestamibi scintigraphy...
