An Unusual Cause of Hypokalemia in an Elderly Man with Hypertension
Hypokalemia in the elderly usually results from gastrointestinal loss or the use of diuretics. However, primary aldosteronism should be considered in hypertensive patients with metabolic alkalosis and unexplained hypokalemia with hyperkaliuresis. We report a 63 year-old hypertensive man with such me...

However, primary aldosteronism should be considered in hypertensive patients with metabolic alkalosis and unexplained hypokalemia with hyperkaliuresis.

Abdominal computed tomography showed bilaterally enlarged adrenal glands, and a nuclear medicine study supported the diagnosis of bilateral adrenal hyperplasia. |
