Overview
CT scan may aid in visualizing adrenal adenomas for lesions that are amenable to surgery.
CT scan
Adrenal adenomas may display the following features of CT scanning:
- Aldosteronomas are homogeneous and hypodense.
- The signal intensity may be near to <10 HU.
- No contrast enhancement
- Non-calcified
If CT findings are negative, selective adrenal venous sampling for aldosterone or a dexamethasone suppressed iodocholesterol adrenal scan may identify the tumor.
