Background. Primary hyperaldosteronism is an uncommon cause of hypertension in the general population. Given the mechanism of action of aldosterone clinical manifestations may not occur in the setting of end stage renal disease. However, if a successful renal transplant is performed clinical manifestations may occur. Methods. We present a case of a patient with a preexisting adrenal adenoma who only presented with clinical signs of hyperaldosteronism after renal transplantation. Patients' work-up included plasma aldosterone, plasma renin activity, serum cortisol, and estimation of trans tubular potassium gradient. Results. The patient's serum aldosterone was markedly elevated with a relatively suppressed plasma renin activity. Trans tubular potassium gradient was high in the presence of hypokalemia. Conclusion. Previously silent hyperaldosteronism may be unmasked by a successful renal transplant.
