It’s common for adrenal nodules to turn up on imaging scans. Most of the time, they don’t cause symptoms and don’t need treatment. Here’s what to know.
There are two adrenal glands, one above each kidney. Each gland has two types of tissue: the cortex and the medulla. Benign adrenal tumors that grow in the cortex are called adrenal adenomas. Those that grow in the medulla are called pheochromocytomas (fee-o-kroe-moe-sy-TOE-muhs).
An adrenal adenoma is a benign (noncancerous) tumor that forms in your adrenal glands. It’s the most common type of adrenal gland tumor. Most adrenal adenomas don’t produce symptoms or require treatment. However, some adenomas may cause your adrenal glands to secrete excess hormones, like cortisol.
A nodule can disrupt adrenal gland function and trigger a wide variety of symptoms, such as unexplained changes in body weight, high blood pressure, headaches, muscle spasms, decreased sex drive and fatigue.
When imaging reveals a nodule in an adrenal gland, several steps are taken to confirm whether it's a noncancerous, or benign, adenoma. The images are evaluated closely to examine the nodule's appearance.
Adrenal nodules are abnormal growths or masses that develop in the adrenal glands, located on top of each kidney. These nodules often appear incidentally during imaging tests done for unrelated health concerns.
Adrenal nodules (aka mass, lesion, tumor) are growths that occur in the adrenal gland forming a lump or bump within the otherwise smooth, even adrenal. Adrenal nodules are common in older people (occurring in 7-10%), but less common (but often even more important) in younger people.
