The case of a neonate is presented who had late onset seizure associated wi th hypocalcemia, hyperphosphatemia, and raised parathyroid hormone. The inf ant did not have any stigmata of pseudohypoparathyroidism, The hypocalcemia was initially resistant to calcium therapy, but responded to vitamin D ana log therapy. The diagnosis of 'transient neonatal pseudohypoparathyroidism' was entertained, as the infant remained stable and seizure-free with norma l serum biochemistry during 8 months of follow-up.
