Hypoparathyroidism describes a condition in which there are low circulating levels of parathyroid hormone (PTH) or insensitivity to its action.1 The causes of hypoparathyroidism vary; however, they all share a common feature of hypocalcemia. The presentation of hypoparathyroidism also varies depending on the chronicity of the resultant hypocalcemia. Muscle...

Hypoparathyroidism is a condition of parathyroid hormone (PTH) deficiency. Primary hypoparathyroidism is a state of inadequate PTH activity. In the absence of adequate PTH activity, the ionized calcium concentration in the extracellular fluid falls below the reference range. Primary hypoparathyroidism, the subject of this article, is a syndrome resulting from iatrogenic...

Hypoparathyroidism results from defective synthesis or secretion of parathyroid hormone (PTH), end-organ resistance, or inappropriate regulations that result from the activated or antibody-stimulated calcium-sensing receptor (CaSR).1 These defects can be inherited or acquired. PTH secretion by the parathyroid glands (prime regulators of serum calcium concentration) maintains serum calcium within a...

A 62-year-old man with idiopathic hypoparathyroidism and extensive paravertebral and ligamentous ossification is reported. The clinical and radiological findings of this, and other reported cases, are discussed and compared with other causes of paravertebral ossification.
