Overview
Epidemiology and Demographics
Incidence and Prevalence
- The incidence and prevalence of adrenal incidentalomas can only be extrapolated from imaging or autopsy studies.
- Autopsy studies suggest a prevalence of clinically unapparent adrenal masses of around 2% (range 1.0–8.7%)
- Radiological studies report a frequency of around 3% in the age of 50years, which increases up to 10% in the elderly (2, 5, 6, 7, 14, 15, 16).
Age
- The prevalence of adrenal incidentaloma is higher in older patients (10 percent) [5].
- In childhood, adrenal incidentalomas are extremely rare.
- The prevalence of adrenal incidentalomas increases with age
- it is less than 1% in patients younger than 30 yr of age and up to 7% in patients over age 70 (3, 4, 7).
- The prevalence is higher in obese, diabetic, and hypertensive patients [5].
Race
- There is no racial predilection to incidentaloma.
Gender
- Incidentaloma affects men and women equally.
