Extensive intracranial calcification presenting with neurological symptoms due to primary hypoparathyroidism and secondary hyperparathyroidism: Two case reports

Metastatic calcification involving basal ganglion in idiopathic hypoparathyroidism (IHPT) and intracranial vascular calcification in secondary hyperparathtyroidism (SHPT) in end-stage renal disease (ESRD) on hemodialysis are not uncommon. Extensive bilateral symmetrical intracranial calcification involving basal ganglion, cerebellum and white matter presenting with neurological symptoms has been rarely reported in literature. We report 2 such cases. The first case belongs to a 56 year-old lady with IHPT with extensive intracranial calcification who presented with choreoathetotic movements. The second case is concerning a 14 year-old boy with SHPT with ESRD on hemodialysis with extensive intracranial calcification who presented with seizures. The possible pathogenesis of extensive metastatic calcification and treatment was discussed with review of literature.
