Lateralización de la secreción de aldosterona en la hipertensión secundaria

Abstract

We present the case of a 33-year old woman with arterial hypertension and symptomatic hypokalemia who was treated with beta blockers and diuretics, with subsequent addition of telmisartan and potassium. In Nephrology, all of her medication was replaced by an alpha blocker and she was admitted for study of secondary hypertension. During her hospitalization, the existence of hypokalemia, hyperkaliuria, low basal and post-stimulation plasma renin, elevated basal and post-stimulation aldosterone, elevated aldosterone/plasma renin ratio was verified. The abdominal CT scan demonstrated the existence of a left adrenal gland mass, confirming aldosterone hypersecretion by catheterization of the adrenal veins and adrenal scintigraphy with 131Icolesterol, laparoscopically excising the mass. The diagnosis was Conn's syndrome due to left adrenal adenoma. The interest of this case is due to the diagnostic difficulty based on imaging tests and the aid of the adrenal vein catheterization.
