Primary aldosteronism (PA) is defined as an autonomous over-production of aldosterone by the zona glomerulosa of the adrenal glands. It is classically considered as a rare cause of hypertension. Aldosterone producing adenoma (APA) and idiopatic hyperoldosteronism (IHA) represent the most frequent subtypes of PA. The authors report 18 cases of PA (14 women an 4 men) with a mean age of 42 +/- 13.5 years. All patients have hypertension and hypokaliemia (K < 3.5 mmol/l). Eleven patients have an APA, one patient has an adrenal carcinoma and three patients have IHA. The subtype of PA has not been established in three patients. We discuss in this article the clinical, biological, radiological and evolutif characteristics of our cases, and we insist on the necessity of making a precise etiologic diagnosis to propose the most adequate treatment.
