File:CT of adrenal adenoma.jpg
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:
  • Within 1 month for attenuation value
  • After 6 months for size control
