“…Routine biochemistry findings are not generally diagnostic in hypertensive patients but hypokalemia with metabolic alkalosis and serum sodium levels close to high-normal should remind one of PA (8). In PA diagnosis, the following criterias support the diagnosis: 1-Plasma aldosteron/ renin ratio > 30 and plasma aldosterone level > 25 ng/ dl provide a sensitivity 90% and a specificity 91% for the diagnosis of primary aldosteronizm (9), 2-No aldosterone suppression in sodium loading test, 3-Unilateral adenoma that is detected with high-resolution computed tomography (HRCT) (10). The case was presented because of severe hypokalemia and associated rhabdomyolisis development and extraordinary polyuria development about 19 L/day.…”
