BACKGROUND: Primary Aldosteronism is the commonest cause of secondary arterial hypertension and is due to uncontrollable aldosterone secretion by a series of adrenal disorders. DESCRIPTION OF THE CASE: We describe a case of a 71-year-old female patient with uncontrollable hypertensive peaks in soils of pre-existing arterial hypertension, who was diagnosed with Primary Aldosteronism. CONCLUSION: Both late onset of the disease and bilateral presence of adrenal nodes are rarely described in the literature and selection of treatment mainly depends on adrenal vein catheterization.
