Recurrence of adrenal aldosterone-producing adenoma

Conn's syndrome (adrenal aldosterone-producing adenoma) and bilateral adrenal hyperplasia are the most common causes of primary aldosteronism. The treatment of choice for patients with aldosterone-producing adenoma is unilateral total adrenalectomy. Recurrence after adequate surgery is exceptional. We present a patient with recurrence of an aldosterone-producing adenoma in me right adrenal gland 9 years after adenomectomy of a aldosterone-producing adenoma in the same adrenal gland. We conclude that adenomectomy is not an adequate therapy for patients with adrenal aldosterone-producing adenoma.
