title: A case of maternal hyperparathyroidism presenting as neonatal tetany.
abstract: A three-week-old infant presented with tetany and with serum calcium and phosphate levels compatible with the diagnosis of hypoparathyroidism. Investigation of the asymptomatic mother revealed serum calcium and phosphate levels and urinary phosphate clearance values diagnostic of hyperparathyroidism. The maternal hyperparathyroidism was treated by removal of a parathyroid adenoma.
