Intraventricular hemorrhage is an uncommon problem in the full-term newborn. In a review of 19 full-term infants with intraventricular hemorrhage diagnosed on computed tomography prior to 1 month of age, thalamic hemorrhage associated with the intraventricular hemorrhage was documented in 12 infants. Thus, thalamic hemorrhage appears to be the most common source of intraventricular hemorrhage in this age group, particularly in infants who had uneventful birth histories and in whom clinical abnormalities (signs of increased intracranial pressure, seizures, altered level of consciousness) developed after the first week of life. The majority of these infants had predisposing factors for cerebral venous infarction such as sepsis, cyanotic congenital heart disease, and coagulopathy. The clinical appearance and outcome for infants with thalamic hemorrhage/intraventricular ular hemorrhage were similar to those in infants with intraventricular hemorrhage originating from other sites, except for an increased incidence of cerebral palsy in infants with thalamic hemorrhage/intraventricular hemorrhage. Definitive diagnosis was made on the basis of characteristic radiologic abnormalities.
