What is parathyroid adenoma?

Parathyroid adenoma is a benign tumour of the parathyroid glands, which overproduces parathyroid hormone and causes primary hyperparathyroidism.

Hyperparathyroidism is diagnosed through blood tests, physical examination and history. However, finding the cause of hyperparathyroidism and differentiate it from other causes leading to a rise in blood calcium requires a combination of blood and specialised imaging tests.
