Parathyroid Adenoma
Medically reviewed by Drugs.com. Last updated on May 6, 2024.
What is a parathyroid adenoma?
A parathyroid adenoma is a benign (not cancerous) tumor on one or more of your parathyroid glands. The parathyroid glands are 4 small glands located near the thyroid gland in your neck. The parathyroid gland produces parathyroid hormone (PTH). PTH keeps the level of calcium balanced in your blood. A parathyroid adenoma can cause extra PTH to be produced. This condition is called hyperparathyroidism. Hyperparathyroidism can cause blood calcium levels to increase, and lead to health problems such as osteoporosis (weak, brittle bones). The cause of parathyroid adenomas is usually not known.

How is a parathyroid adenoma diagnosed and treated?
Blood tests may show increased levels of parathyroid hormone and calcium. An ultrasound, CT scan, or MRI may be done. You may be given contrast liquid to help the adenoma show up better in the pictures. Tell the healthcare provider if you have ever had an allergic reaction to contrast liquid. Do not enter the MRI room with anything metal. Metal can cause serious injury. Tell the healthcare provider if you have any metal in or on your body. Surgery may be done to remove the adenoma or parathyroid gland.
