Extensive Calcifications on Brain MRI in a case of Hypoparathyroidism

16-year old presented with seizures of five years duration. Seizures were of generalized tonic-clonic type. He was earlier diagnosed to have hypoparathyroidism on the basis of low serum calcium and low PTH levels in blood.

MRI brain showed bilateral symmetrical calcifications involving caudate nucleus, globus pallidus, thalamus and dentate nucleus of cerebellum. Calcifications were hyperintense on T1W images and were suppressed on susceptibility weighted imaging. The cause of calcification is supposed to be elevated serum phosphate levels.

For seizures, he was started on sodium valproate. He remained seizure-free on that. For hypoparathyroidism, he was started on calcium supplements and active vitamin D. There was significant clinical improvement with medical treatment.
