NIH state-of-the-science statement on management of the clinically inapparent adrenal mass ("incidentaloma").

CONCLUSIONS: The management of clinically inapparent adrenal masses is complicated by limited studies of incidence, prevalence, and natural history, including the psychologic impact on the patient who is informed of the diagnosis. Improvements in the resolution of abdominal imaging techniques combined with increased use of abdominal imaging suggest that the prevalence of clinically inapparent adrenal masses will continue to escalate. The low prevalence of adrenal cortical carcinomas and the relatively low incidence of progression to hyperfunction call into question the advisability of the current practice of intense, long-term clinical followup of this common condition. All patients with an incidentaloma should have a 1-mg dexamethasone suppression test and a measurement of plasma-free metanephrines. Patients with hypertension should also undergo measurement of serum potassium and plasma aldosterone concentration/plasma renin activity ratio. A homogeneous mass with a low attenuation value (less than 10 HU) on CT scan is likely a benign adenoma. Surgery should be considered in all patients with functional adrenal cortical tumors that are clinically apparent. All patients with biochemical evidence of pheochromocytoma should undergo surgery. Data are insufficient to indicate the superiority of a surgical or nonsurgical approach to manage patients with subclinical hyperfunctioning adrenal cortical adenomas. Recommendations for surgery based upon tumor size are derived from studie...
