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.

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 characterisation is helpful ⁵.
