Ten-year follow-up report and neurologic sequelae in a case of neonatal severe primary hyperparathyroidism.

We present a 10-year follow-up and describe our experience in managing a case of neonatal severe primary hyperparathyroidism (NSHPT) for the first time in Iran. Microcephaly, mental retardation, and epilepsy may be long time sequels of NSHPT. The brain MRI findings are compatible with an old hypoxic-ischemic event.
