Answer

Intracranial hemorrhage occurs more frequently in premature than in term infants. Distinguishing infants with pure hypoxic-ischemic encephalopathy from those with intracranial hemorrhage often is difficult.

Subarachnoid hemorrhage is more common in term infants. This type of hemorrhage occurs frequently and is not clinically significant. Typically, infants with subarachnoid hemorrhage appear remarkably well.

Germinal matrix-intraventricular hemorrhage is seen more frequently in premature than in term infants, particularly in infants born prior to 34 weeks' gestation. Subtle seizures are seen frequently with this type of hemorrhage.

Subdural hemorrhage is seen in association with cerebral contusion. It is more common in term infants.
