Figure 1
Figure 1 Non-contrast computed tomography is the cornerstone of imaging assessment of adrenal incidentalomas. A: Non-contrast computed tomography (ncCT) demonstrates an adrenal incidentaloma (ADI) with a density < 10 Hounsfield units (HU); B: Axial ncCT shows bilateral ADIs < 10 HU; C: Axial ncCT shows a lipid-poor left ADI with attenuation > 10 HU. HU: Hounsfield units.

Figure 2 Simplified OODA loop (observe, orient, decide, act) management algorithm for adrenal incidentalomas. For the more detailed form of this algorithm see the Supplementary Figure 1. HU: Hounsfield units; ACC: Adrenocortical carcinoma; PCC: Pheochromocytoma; F/U: Follow-up; Sx: Surgery; Tx: Therapy.
