Absence of Hydrocephalus despite Disproportionately Increasing Head Size after the Neonatal Period in Preterm Infants with Known Intraventricular Hemorrhage

Abstract

Of a group of 20 infants weighing less than 1,250 g at birth and surviving with intraventricular hemorrhage (IVH) documented by computed tomography, 6 exhibited excessive head growth between 6 and 14 weeks after birth with no evidence of neurologic deterioration. Repeat computed tomography was normal in all 6 infants. Rapid head growth after the immediate neonatal period can be expected in some infants with a history of lesser degrees of IVH and is not in itself indicative of posthemorrhagic hydrocephalus.
