Young adults are rarely affected by adrenal incidentalomas; the average age is over 50.

With the widespread use of imaging studies, adrenal incidentalomas are a common clinical issue, affecting up to 5% of the adult population (1, 2). The majority of adrenal incidentalomas are nonfunctional adenomas (NFAA), but many cause mild autonomous cortisol secretion (MACS), also known as autonomous cortisol secretion. The MACS diagnosis is based on the results of the 1-mg dexamethasone suppression test in patients with an adrenal adenoma.
