Current Management of Adrenal Incidentalomas

Adrenal “incidentalomas” refer to a group of adrenal masses initially discovered during cross-sectional imaging obtained for other clinical reasons. The majority of incidentalomas are benign nonfunctional adrenal adenomas and can be safely managed expectantly. A subset of adrenal incidentalomas, however, are functional and/or malignant, and these lesions most often require adrenalectomy. The following chapter outlines the differential diagnosis, the different imaging modalities and features, as well as biochemical evaluation of adrenal incidentalomas.
