Parathyroid Adenoma


CT – Enhancing mass (isodense to thyroid) inferior to the left lobe of the thyroid.

US – Oval marginated hypervascular mass posterior to the inferior pole of the left lobe of the thyroid.


The parathyroid glands produce parathyroid hormone which regulates calcium. PTH promotes the renal tubular absorption of calcium, decreases tubular reabsorption of phosphate increasing calcium retention, and stimulates osteoclasts and vitamin D production, all of which raise serum calcium. Primary hyperparathyroidism is diagnosed when serum calcium is elevated and PTH is increased or inappropriately normal. Symptoms include fatigue, hypertension, bone pain, weakness and psychiatric disease. Primary hyperparathyroidism is most common in late adulthood and affects females four times as often as males. Most cases of primary hyperparathyroidism are caused by a single sporadic parathyroid adenoma; rarely hyperplasia of all four glands, double adenomas, and parathyroid carcinoma.
