Overview
Effective measures for the secondary prevention of adrenal incidentaloma include annual biochemical follow-up for up to 5 yr, no routine follow-up of adrenal incidentalomas with a non-contrast attenuation value no greater than 10 HU. Patients with adrenal masses less than 4 cm in size and a non-contrast attenuation value more than 10 HU should have a repeat CT study in 3–6 months and then yearly for 2 yr.
Secondary Prevention
Effective measures for the secondary prevention of adrenal incidentaloma include:[1][2][3][4][5]
- Excess hormone secretion may develop in up to 20% of patients with previously non-functional adrenal tumors during follow-up.
- The transformation rate of non-functional adrenal masses to functional tumors seems to be higher in adrenal masses greater than 3 cm in size.
- Annual biochemical follow-up for up to 5 years may be reasonable for patients with adrenal incidentalomas, especially if the tumor is more than 3 cm in size.
- No routine follow-up of adrenal incidentalomas with a non-contrast attenuation value no greater than 10 HU.
- Malignancy can be detected by an absolute increase in size of 0.8 cm, 0.64 cm growth per year or a 25% increase in size per year.
- A one-time follow-up scan in 6–12 months may be reassuring to the physician and the patient.
- Patients with adrenal masses less than 4 cm in size and a non-contrast attenuation value more than 10 HU should have a repeat CT study in 3–6 months and then yearly for 2 yr.
- Surgical excision may be considered for tumors with indeterminate radiological features that grow at least 0.8 cm over 3- to 12-month follow-up.
