Axial slice of CT without contrast, showing an adenoma. It has low attenuation, and well-defined margins.
Incidentalomas
Adrenal masses discovered incidentally ("incidentalomas") have the following workup by Swedish national guidelines:[1]
| Features | Workup | ||
|---|---|---|---|
| Size < 1 cm | No radiologic workup needed (but biochemical screening may be indicated if clinical suspicion of being hormonally active) | ||
| Size 1 to 4 cm | Attenuation ≤10 HU (adenoma) | ||
| Attenuation >10 HU | Without IV contrast | CT after 6 months, then stop if size is unchanged | |
| On contrast CT | CT without contrast as either:
