Asymptomatic Hyperinsulinemic Hypoglycemia and Grade 4 Intraventricular Hemorrhage in a Late Preterm Infant.

Hyperinsulinemic hypoglycemia (HH) has the potential to cause acute neurologic dysfunction and neurodevelopmental impairment. Parieto-occipital neuronal injuries have been reported in hypoglycemic infants, but intraparenchymal hemorrhage is rare. On day 5 of life, a late preterm infant was transferred to our care with recurrent asymptomatic hypoglycemia.
