To the editor: Aldosterone-producing adenoma and hyperplasia are found in most patients with primary aldosteronism. The distinction between the two is important because surgery is likely to cure the hypertension with an aldosterone-producing adenoma but is seldom helpful in hyperplasia. An early morning postural fall in plasma aldosterone—actually the result of diurnal adrenocorticotrophin variation—suggests an aldosterone-producing adenoma, whereas the opposite usually occurs with hyperplasia. We report the case of a patient who was incorrectly thought to have hyperplasia because of a postural rise in plasma aldosterone.
