Abstract
Recurrent hyperparathyroidism can occur following quadruple parathyroidectomy and during radical parathyroidectomy and so that future hypoparathyroidism is avoided autotransplantation of parathyroid tissue is often preformed. Herein, I describe a patient who was thought to have recurrent hyperparathyroidism following a quadruple parathyroidectomy based solely on a high intact parathyroid hormone level. The patient neither had clinical symptoms or signs of hyperparathyroidism nor did the laboratory data other than the increased intact PTH level suggest hyperparathyroidism. A more comprehensive history revealed the cause of the elevated intact PTH so that further expensive, invasive, and potentially dangerous investigations were avoided.
