An adrenal incidentaloma is a mass on an adrenal gland. It is found during image testing for a different problem. The adrenal glands sit on top of each kidney.
It may be caused by the gland making too much hormone. It may also be caused by tumors or cysts.
The image testing that was done is used to diagnose this problem. Blood and urine tests will also be done.
Most people do not need to be treated. Surgery may be done to remove a gland that is causing problems.
