Abstract
Twenty neonates with a suspected intracranial hemorrhage were studied by computed tomography (CT). The exact site and extent of the hemorrhage in all infants were clearly demonstrated on serial CT scans. In intraventricular hemorrhage, a dense subependymal halo lined the ventricular system and could be recognized for up to 2 weeks. Discrete hemorrhage adjacent to the ventricular system also appeared as discrete nodules rather than as a diffuse hemorrhage. Blood in the ventricular system could be recognized up to 2 weeks when there were blood-cerebrospinal fluid levels. Hydrocephalus was a common sequela and was readily detectable before a measurable change in head size.
