A Rare Adrenal Incidentaloma That Mimics Adrenocortical Carcinoma

Figure 1

Adrenal-protocol CT abdomen, coronal demonstrates a 5 × 6.7 × 7 cm right adrenal mass (white arrows) with areas of calcification. Hounsfield units (HU): nonenhanced 36 HU (>10 HU indeterminate for adenoma), enhanced 84 HU, and delayed 73 HU. Absolute washout 22.9% (<60% indeterminate for adenoma) [3].
