A Case Report on Uncontrolled Arterial Hypertension as an Underlying Cause of Conn´s Syndrome

A 24-year-old woman who consulted for uncontrolled high blood pressure. Four years ago, was diagnosed with high blood pressure and was treated with many medications without achieving adequate control. On treatment with irbesartan, hydrochlorothiazide, amlodipine. Patient has not family history. Blood pressure of 180/110mmHg was found upon evaluation. Examinations showed evidence of hypokalemia and normal renal function. Chest X-rays and electrocardiogram were normal. Ultrasound Doppler of renal arteries without alterations. Blood aldosterone was measured with values of 22ng/dl and an abdominal tomography showed the presence of a left adrenal adenoma. Spironolactone was orally given at a dosage of 25mg every day, titration every week, reaching a dose of 100mg every day, an education plan with a salt-restricted diet and adequate physical activity was provided. So, it is concluded that Primary aldosteronism is the primary endocrinological cause of secondary hypertension and only 30% of patients have hypokalemia.
