Adenoma suprarrenal productor de aldosterona

Diana Mara Rodrguez, Alejandro Pinzn

La hipertensin arterial secundaria es ms comn en individuos menores de 30 aos, la mayor parte son de causa renovascular; la etiologa endocrina es excepcional, el hiperaldosteronismo primario slo ocupa de 5-15%, el sndrome de Conn corresponde a 0.05-2.2% de la poblacin de hipertensos y es una de las pocas causas potencialmente curables de hipertensin, por lo que consideramos este caso digno de ser revisado. Se presenta un hombre de 63 aos de edad con hipertensin arterial diagnosticada hace 25 aos, en tratamiento con mltiples antihipertensivos, incluido el minoxidil sin control de cifras tensionales, que consulta a endocrinologa por aparicin de vello facial. Se consider hipertensin arterial secundaria y se hall hipokalemia. La relacin de aldosterona y renina elevada, sugera la presencia de hiperaldosteronismo, que se localiz con venografa de suprarrenales. La extirpacin quirrgica de la lesin confirm el diagnstico de adenoma adrenocortical. Despus de la ciruga mejor el control de la tensin arterial y tras suspender el minoxidil, la hipertricosis desaparece. (Acta Med Colomb 2014; 39: 191-195).

Aldosterone-producing adrenal adenoma

Diana Mara Rodrguez, Alejandro Pinzn

Secondary Hypertension is more common in individuals under 30; most have renovascular etiol- ogy; endocrine etiology is exceptional; primary hyperaldosteronism is only responsible for 5-15%, Conn syndrome corresponds to 0.05-2.2 % of the hypertensive population and is one of the few po- tentially curable causes of hypertension, so we consider this case worthy to be revised. A 63 year old man diagnosed with hypertension 25 years ago and treated with multiple antihypertensives including minoxidil, with uncontrolled blood pressure readings, which consults to endocrinology for appearance of facial hair, is presented. Secondary hypertension was considered, and hypokalemia was found. The ratio of aldosterone and high renin, suggested the presence of hyperaldosteronism which was local- ized by adrenal venography. Surgical removal of the lesion confirmed the diagnosis of adrenocortical adenoma. After surgery, control of blood pressure improved and after discontinuation of minoxidil, hypertrichosis disappears.
