A rare cause of neonatal hypercalcemia: Neonatal severe primary hyperparathyroidism: A case report and review of the literature

Abstract

Highlights • Neonatal severe primary hyperparathyroidism is an exceedingly rare condition that has high mortality and morbidity if left untreated.• Medical therapy must be initiated as soon as the condition is diagnosed, and early surgery must be performed in patients who are refractory to the medical therapy.• Scintigraphic studies might sometimes fail to detect ectopic parathyroid glands. Intraoperative parathormone monitoring is particularly important to ensure complete removal of the parathyroid glands.
