A 51-year-old woman presented with sudden-onset dysphonia that was caused by acute vocal cord paralysis as a result of bleeding within a hyperplastic upper right parathyroid gland. She was referred to our hospital for the treatment of secondary hyperparathyroidism due to chronic renal failure. She had been receiving hemodialysis for 7 years and had developed parathyroid hyperplasia associated with severe hypercalcemia and hyperphosphatemia. An acute onset of vocal cord paralysis is rarely associated with benign processes, and, to our knowledge, the case reported herein is the first one that has been associated with secondary parathyroid hyperplasia.
