A case of primary aldosteronism with secondary hyperparathyroidism and bilateral adrenal tumors

Abstract

A 43-year-old Japanese woman was admitted to our hospital with weakness. Laboratory findings showed hypokalemia, hypocalcemia and elevation of the serum creatinine phosphokinase levels, but intact parathyroid hormone levels. Further evaluations suggested that she had primary aldosteronism (PA), secondary hyperparathyroidism and bilateral adrenal tumors. She was treated successfully by laparoscopic right adrenalectomy. This case not only serves to the diagnosis of bilateral adrenal tumors in which selective adrenal venous sampling (SAVS) proved to be useful, but also for physicians to be aware of secondary hyperparathyroidism and the risk of secondary osteoporosis caused by PA.
