Normohormonal primary hyperparathyroidism is a distinct form of primary hyperparathyroidism

Normohormonal primary hyperparathyroidism represents 22.5% of our primary hyperparathyroidism population, which is greater than reported previously. It is a distinct disease process from classic primary hyperparathyroidism in presentation, imaging, and operative findings. More hyperplasia and a lesser gland weight make it challenging to resect the ideal amount of tissue. Studies with long-term follow-up are needed to determine optimal operative management.
