Síndrome de Conn

Abstract

Aldosteronoma is a suprarrenal cortex tumor producer of aldosterona and it is the main cause of primary hyperaldosteronism, is diagnosed mainly among 30 and 60 years old, predominantly in women 1.5:1, usually unilateral but occasionally bilateral (8%). Most patients with hyperaldosteronism have normal serum potassium levels at diagnosis, which should not be an exclusion criterion for the diagnosis. We must suspect aldosteronoma in patients with hypertension, hypokalemia and metabolic alkalosis. Also we can search in patients with family history of primary hyperaldosteronism, incidentaloma, hypertension and previous study of secondary hypertension. This paper reports the case of a 39-year-old female patient, with hypertension and hipokalemia. The diagnosis has made with high aldosteron serum levels and abdominal computed axial tomography, which showed a right adrenal tumor without renal involvement. The laparoscopic adrenalectomy and pathology study confirmed aldosteronoma. Aldosteronoma has a diverse clinical presentation, this is why we need to establish it as a differential diagnosis in patients with secondary hypertension. Laparoscopic adrenalectomy is the gold standard treatment for the aldosteronoma.
