Adrenal Adenoma

An adrenal adenoma is a common type of adrenal nodule that is often benign. Imaging may suggest adenoma when the lesion has reassuring features, but doctors still consider size, growth, and whether the lesion could produce hormones.

In many reports, this wording is a clue for your doctor to interpret rather than a diagnosis by itself. The overall concern level depends on the surrounding findings, and follow-up is often guided by symptoms, prior scans, or whether the area is changing over time.

An adrenal adenoma is a usually benign adrenal gland nodule often found incidentally.

What it means

An adrenal adenoma is a common type of adrenal nodule that is often benign. Imaging may suggest adenoma when the lesion has reassuring features, but doctors still consider size, growth, and whether the lesion could produce hormones.

Also seen as: adrenal incidentaloma, adrenal nodule.

What matters most on a report

This term becomes more or less important depending on its size, location, severity, associated symptoms, and whether it is new compared with earlier imaging. Radiologists usually expect the finding to be read alongside the rest of the report instead of in isolation.

How common it is

Incidental adrenal nodules are common on abdominal imaging.

Common incidental adrenal finding

Adrenal nodules are frequently reported on abdominal CT and MRI performed for other reasons.

Common causes

  • Benign adrenal adenoma
  • Incidental adrenal mass with benign features
  • Other adrenal tumors
  • Metastatic disease in some settings

When doctors worry

  • The lesion is large, growing, or indeterminate
  • The report mentions atypical density or suspicious enhancement
  • Symptoms or lab findings suggest hormone production

Typical follow-up

  • Review imaging features
  • Consider endocrine lab work
  • Monitor selected lesions over time

Common misunderstandings

A radiology finding name can sound more definite than it really is. Many findings describe an imaging pattern, not a final diagnosis, and many turn out to be less urgent once doctors match the wording with your symptoms, exam, and any earlier studies.

Frequently asked questions

Does adenoma mean cancer?

No. Adenoma generally suggests a benign gland-related growth.

Why might hormone testing be suggested?

Some adrenal lesions can produce hormones, so clinicians may order labs.
