The case of a
neonate is presented
who had early onset seizure associated with
hypocalcemia,
hyperphosphatemia, and raised
parathyroid hormone. The
infant did not have any
stigmata of
pseudohypoparathyroidism. The
hypocalcemia was initially resistant to
calcium therapy, but responded to
vitamin D analog
therapy. The
diagnosis of 'neonatal
pseudohypoparathyroidism' was entertained; the
infant remained stable and seizure-free with normal
serum biochemistry during 3 months of follow-up.
