These tumors may be functional and produce cortisol, aldosterone, catecholamines, and rarely testosterone and other sex hormones. In many cases, the tumors are nonfunctional and are removed because of the concern for cancer or growth. In these situations, the adrenal mass is frequently found during abdominal imaging done for unrelated indications. These so-named adrenal incidentalomas generally should be removed if they have a cross-sectional diameter of 4 cm or greater or if they are proven to be functional. Patients with nonfunctional adrenal masses smaller than 4 cm without concerning radiographic features should be followed with periodic imaging to monitor changes in the size of the mass.
