Hyperparathyroidism is due to increased activity of the parathyroid glands, either from an intrinsic abnormal change altering excretion of parathyroid hormone (primary or tertiary hyperparathyroidism) or from an extrinsic abnormal change affecting calcium homoeostasis stimulating production of parathyroid hormone (secondary hyperparathyroidism). Primary hyperparathyroidism is the third most com...

brown tumors may occur secondary to hyperparathyroidism in patients with chronic renal failure (ckd). they are increasingly rare because hyperparathyroidism in now diagnosed and treated at an early stage. we report 67-year-old man who had been on hemodialysis for crf for over 3 years, who presented with back pain over the thoracolumbar junction from 2 years ago and because of pain he could not ...

Fahrs syndrome is a rare anatomoclinical entity whose main etiology primary or postoperative hypoparathyroidism. It characterized by bilateral and symmetrical intracerebral calcifications, localized in the basal ganglia. Hypoparathyroidism, postoperative, most classic anomaly. Hyperparathyroidism exceptionally reported as cause of Fahr syndrome. We report case 30-year-old woman who presented wi...

Primary hyperparathyroidism, a common endocrine disorder, is traditionally defined by hypercalcemia and elevated levels of parathyroid hormone (PTH). A newer presentation of primary hyperparathyroidism has been described over the past decade, in which PTH is elevated but serum calcium is consistently normal, in the absence of secondary causes of hyperparathyroidism, such as renal disease or vit...
