What is an adrenal nodule?

An adrenal nodule is a small abnormal growth or mass that forms within the adrenal gland, which is located on top of each kidney. These nodules are often discovered incidentally during imaging tests, such as a CT scan or MRI, that are done for unrelated reasons.

Adrenal nodules can be either benign (non-cancerous) or malignant (cancerous). Most adrenal nodules are benign and do not cause any symptoms. However, some nodules may produce excessive hormones, leading to symptoms such as high blood pressure, weight gain, and changes in mood and energy levels.

Diagnosing an adrenal nodule typically involves imaging tests, hormone tests, and sometimes a biopsy to determine if the nodule is benign or malignant. Treatment options for adrenal nodules include observation, medication to control hormone production, or surgery to remove the nodule.

Overall, most adrenal nodules are harmless and do not require treatment. However, it is important to monitor them regularly and consult with a healthcare provider to determine the best course of action.
