Primary Aldosteronism due to a Sub Centimeter Unilateral Adrenal Adenoma

Abstract

Primary hyperaldosteronism is one of the underdiagnosed causes of hypertension. The studies showed an incidence around 11% of patients with newly diagnosed HTN.The sporadic causes of primary hyperaldosteronism are the most common cause of the disease -bilateral hyperplasia of both adrenal glands is the cause in 60-70% of the sporadic cases of the disease and the unilateral aldosterone producing adenomas is accounting for 30-40% of the sporadic causes of the disease. Much less common cause of sporadic primary hyperaldosteronism are the adrenal carcinomas producing aldosterone or unilateral adrenal hyperplasia. There are familial causes of primary hyperaldosteronism as well which are very rare/2/.
