Pseudohypoparathyroidism

A 38-year-old healthy female was referred for evaluation and management of hypocalcemia discovered incidentally during medical evaluation. She complained of intermittent mild tingling paresthesias and occasional muscle cramps in her legs. She had never had tetany, bronchospasm, laryngospasm, cardiac rhythm disturbances, seizures, or loss of consciousness. She had been advised by her primary care physician to take supplemental calcium carbonate with 500 mg elemental calcium once a day and calcitriol 0.25 mcg twice a day, but she did not take these supplements on a regular basis.
