An unusual case of neonatal seizures as manifestation of asymptomatic maternal hypoparathyroidism. Neonatal hypoparathyroidism is one of the rare causes of hypocalcaemia. Several cases of neonatal hypoparathyroidism secondary to maternal hyperparathyroidism have been reported. In this case report, we have a term neonate with normal birth history who presented with late onset hypocalcemic seizures. After excluding polyendocrinopathies and related syndromes, hypocalcaemia seizures were secondary to maternal asymptomatic hypoparathyroidism. Since this is one variety of unusual case of maternal and fetal hypoparathyroidism, further testing was mandatory to confirm familial origin. This focuses on the need for every clinician to test maternal metabolic status in case of neonatal manifestations.
