The cause of primary aldosteronism is an adrenal adenoma in 80% of patients and adrenal gland hyperplasia in 20%
Preferred Examination: The workup in patients in whom primary aldosteronism is suspected usually starts with appropriate biochemical analysis, after which thin-collimation CT is performed. If CT findings are equivocal, radionuclide studies and MRI should be performed. If doubt concerning the diagnosis remains and if CT scans do not show a mass in the adrenal glands, adrenal venous sampling is recommended.
