Long-term MRI findings of a case with persistent hyperinsulinemic hypoglycemia of infancy (nesidioblastosis)

Neonatal hyperinsulinemic hypoglycemia must be suddenly and appropriately diagnosed and treated to prevent any further neurological dysfunction and damage. MRI studies are crucial in nesidioblastosis to define the characteristics and severity of cerebral lesions after hypoglycemia. Long-term radiologic follow-up should be further investigated to predict the neurologic outcome, although the radiologic recovery period was seen in acute or subacute phase of the disease.
