Adrenal lesions (differential)

Adrenal lesions cover a broad spectrum from benign to neoplastic entities. Due to increased use of cross-sectional imaging they are frequently detected as incidental lesions (incidentalomas). If found incidentally, please refer to the Management of Incidental Adrenal Masses: American College of Radiology White Paper 9.

Radiology plays a significant role in differentiation. Cross-sectional imaging is the mainstay of imaging for identifying and assessing adrenal lesions, for which an algorithm to aid characterization is helpful 5. Adrenal enlargement is also - rarely - called adrenomegaly, which can be unilateral or bilateral.
