AbstractWe report three cases of primary aldosteronism associated with autosomal dominant polycystic kidney disease. The diagnosis of primary hyperaldosteronism was based on the presence of hypokalaemia with excessive urinary potassium excretion and/or the characteristic hormonal changes. Renal function impairment due to autosomal dominant polycystic kidney disease could mask hypokalaemia. The interpretation of adrenal imagery may be hindered by adjacent renal cysts. In one case an adrenal adenoma was detected and surgically removed, with only partial correction of the blood pressure. This could be explained by the persisting underlying autosomal dominant polycystic kidney disease. We conclude that in a hypertensive patient with polycystic kidney disease, extrarenal causes of hypertension may be present.
