RESUMO
INTRODUCTION: Primary aldosteronism affects 5% to 13% of patients with hypertension. Idiopathic bilateral hyperplasia (IHA) and unilateral aldosterone-producing adenoma (APA) are the most common types of primary aldosteronism. Bilateral APA is a very rare entity with only a few reports in the literature. We present the case of a patient with metachronous bilateral APA treated with metachronous bilateral total and near total adrenalectomy. CASE REPORT: A 66-year-old female was evaluated for hypokalemia and hypertension refractory to medical therapy 2 years after laparoscopic adrenalectomy for right APA. Follow-up abdominal CT scan revealed a new 1.1-cm left adrenal mass. The patient underwent a laparoscopic near total adrenalectomy for her new left adrenal mass. Pathology examination revealed a new APA. The operation and the patient's postoperative course were uneventful. Potassium levels were normalized and her hypertension became well controlled. CONCLUSION: APA can present metachronously months to years after adrenalectomy for APA in the contralateral adrenal gland. Laparoscopic adrenalectomy remains the approach of choice for this pathology.
