It doesn't cause symptoms, it's caught by chance! If left untreated, it can lead to serious problems.

Adrenal masses often appear without cause. However, certain risk factors can trigger the development of a mass. Prof. Dr. Melih Kara, He notes that advanced age is one of the risk factors, adding, "Furthermore, the presence of a previous malignant tumor, genetic syndromes (such as MEN2, von Hippel-Lindau, and SDH mutations), and the frequent use of certain medications are known to increase risk. These findings once again highlight the diverse factors that play a role in adrenal masses and the importance of personalized assessments in diagnosis and treatment."
It's mostly benign, but…
Masses can form in the adrenal glands, which play a critical role in the healthy functioning of our bodies and enable the production and secretion of hormones such as cortisol, aldosterone, androgens, adrenaline, and norepinephrine. These masses, called adrenal tumors, are basically divided into two groups: hormone-producing and non-hormone-producing. The most common type, an adrenocortical adenoma, is generally benign and does not produce hormones. However, while most do not cause problems, some types of adrenal masses can cause significant health problems. General Surgery Specialist Prof. Dr. Melih Kara lists the problems that can be caused by hormone-secreting masses in the adrenal gland: “Mass producing excessive cortisol can cause Cushing's syndrome. As a result, problems such as obesity, hypertension, diabetes, osteoporosis, and easy bruising can develop. Masses producing excessive aldosterone can cause muscle cramps and fatigue due to resistant hypertension or hypokalemia. If the pheochromocytoma produces hormones, resistant hypertension, tachycardia, recurrent headaches, and transient episodes of high blood pressure can occur.”
