Primary Hyperaldosteronism in a Normotensive Patient: A Case Report.

INTRODUCTION

Primary aldosteronism (PA) is a clinical syndrome characterized by hypertension, suppressed plasma renin activity (PRA), elevated plasma aldosterone concentration (PAC), and spontaneous hypokalemia.

CASE PRESENTATION: We present a 37-year-old normotensive female with hypokalemia, high plasma aldosterone level, and suppressed renin. The patient was treated with eplerenone and potassium chloride supplement. Further investigation with a computed tomography (CT) scan revealed a mass in the left adrenal. Laparoscopic adrenalectomy led to the diagnosis of adrenal adenoma.

CONCLUSIONS

Primary aldosteronism should be among the differential diagnoses in normotensive patients presenting with severe hypokalemia.
