Neurological manifestations in hypoparathyroidism.

Neurological manifestations in three cases of hypoparathyroidism, two of the idiopathic variety and one consequent to thyroidectomy are reported. The rare manifestations included the presentation as paroxysmal kinesogenic choreoathetosis in a twelveyear old boy who had history of seizures in childhood. He responded to carbamazepine. The second case, a known epileptic well controlled on sodium valproate, presented with mental dullness, bone pain and showed features of neuromuscular irritability. Thethird patient presented with raised intracranial tension. He had history of thyroidectomy in the past. The diagnosis was confirmed by the classical blood changes of hypoparathyroidism and the presence of basal ganglia calcification in the two idiopathic cases. All the cases finally responded to combination of calcium and D3.
