A parathyroid adenoma is a noncancerous (benign) tumor of the parathyroid glands, which are located in the neck.
The parathyroid glands in the neck help control calcium use and removal by the body. They do this by producing parathyroid hormone, or PTH. PTH helps control calcium, phosphorus, and vitamin D levels in the blood and bone.
Parathyroid adenomas can be due to a genetic problem. Parathyroid adenomas are the most common cause of hyperparathyroidism (overactive parathyroid glands), which leads to increased blood calcium levels.
Women over age 60 have the highest risk for developing this condition. Radiation to your head or neck also increases your risk.
Exams and Tests
A 24-urine test may be done to check for increased calcium in the urine.
Other tests include:
- Bone density exam
- Kidney ultrasound or CT scan (may show kidney stones)
- Kidney x-rays (may show kidney stones)
- Neck ultrasound
- Sestamibi neck scan (may show swelling of the parathyroid glands)
Surgery is the most common treatment, and it often cures the condition. However, some people choose to only have regular checkups with their health care provider if the condition is mild.
The outlook is generally good.
When to Contact a Medical Professional
