Secondary hypertension defines a wide range of clinical conditions in which the increase in blood pressure (BP) is due, unlike primary hypertension, to an identifiable cause [1]. Although definition of secondary hypertension encompasses the concept that it is curable with specific interventions aimed at removing the cause, this statement unfortunately does not apply to all forms of secondary hypertension (i.e. renal parenchymal disease, polycystic kidney). Common causes of curable secondary hypertension include primary aldosteronism, renal artery stenosis, phaeochromocytoma, and Cushing's syndrome [2].
