Intrauterine Hyperparathyroidism: A Complication of Untreated Maternal Hypoparathyroidism1

Abstract
The clinical course of a 21-yr-old woman with congenital hypoparathyroidism and her fistborn is reported. The woman received minimal treatment with vitamin D. Because of abnormalities found in the roentgenograms of the child''s long bones, it is postulated that the infant had hyperparathyroidism during intrauterine life secondary to the mother''s hypoparathyroidism.
