How common are adrenal incidentaloma?

Adrenal incidentalomas are quite common, and become more common as we age. In autopsy studies of people who died of natural causes, about 6 % of all people have an adrenal mass or adrenal tumor that they were completely unaware of.

How common are incidentalomas?

For example, incidentalomas happened just 2 percent of the time with certain whole-body PET scans and with chest computed tomography (CT) tests to search for blockages in arteries in the lungs. In these situations, incidentalomas were often found in blood vessels.

How fast do adrenal adenomas grow?

The results of our study show that approximately one-third of radiologically proven adrenal adenomas grow over time, and all adenomas that grew did so at a rate less than 3 mm/year, whereas all malignant adrenal nodules grew faster than 5 mm/year.

Do adenomas go away?

Research suggests that most small hepatic adenomas tend to remain stable during observation periods. A small percentage of them disappear. Your doctor can use an ultrasound to monitor the size of the tumor. If you have a large tumor, your doctor may recommend liver resection surgery to remove the tumor.

Is incidentaloma cancerous?

Are Adrenal Incidentalomas Cancer? The vast majority of adrenal incidentalomas are benign and not cancer. Additionally, most adrenal tumors found incidentally do not over-produce any adrenal hormones.

When should adrenal adenoma be removed?

Most adrenal tumors are noncancerous (benign). You may need surgery (adrenalectomy) to remove an adrenal gland if the tumor is producing excess hormones or is large in size (more than 2 inches or 4 to 5 centimeters). If you have a cancerous tumor, you also may need an adrenalectomy.
