Correlation of subtraction parathyroid scintigraphy with weight, pathohistologic finding and oxyphil cell content of parathyroid glands in parathyroid hyperplasia.
BACKGROUND/AIM Parathyroid hyperplasia (PHP) is defined as an absolute increase in the mass of parenchymal cells of the parathyroid gland. PHP is classified as primary, secondary and tertiary. The enlargement of parathyroid glands (PG) is usually asymmetric, resulting in a "dominant" gland. In order to confirm the diagnosis, at least two glands should be examined histologically. Subtotal parath...
متن کاملFunctioning oxyphil parathyroid adenoma.
A hormonally active oxyphil adenoma of the parathyroid masqueraded as a thyroid nodule and was present as a palpable neck mass for more than six years prior to the onset of clinically obvious hyperparathyroidism. The slow evolution of the hyperparathyroidism in the presence of a relatively large adenoma was correlated with the presumptive low hormonal synthetic capacity of oxyphil cells that fo...
متن کاملParathyroid hormone without parathyroid glands.
In mammals, PTH is a component in a complex signaling system involving three structurally related ligands and two G protein-coupled receptors, which share significant amino acid sequence homology (Fig. 1). PTH is a peptide hormone comprising 84 amino acids that is made by the parathyroid glands (and to a much smaller extend by the thymus) and acts through the PTH/PTH-related peptide (PTHrP) rec...
متن کاملParathyroid glands: combination of sestamibi-(99m)Tc scintigraphy and ultrasonography for demonstration of hyperplasic parathyroid glands.
OBJECTIVE To determine the frequency of the types of parathyroid gland hyperplasia and the sensitivity of sestamibi-(99m)Tc (MIBI) scintigraphy and ultrasonography (US) of patients with secondary hyperparathyroidism (SHPT) due to chronic renal failure. MATERIAL AND METHODS We studied 43 patients with SHPT (26 females and 17 males with age range of 27-75 years). Blood tests were performed to d...
متن کاملParathyroid scintigraphy.
Scintigraphy of the parathyroid glands continues to be controversial from several standpoints, including radiopharmaceutical choice, imaging protocol, results, and utility in clinical situations. This article reviews: the anatomy, physiology and pathology of the parathyroid glands; mechanisms of radiopharmaceutical localization; commonly accepted imaging protocols; image results; and the approp...
