[Two cases of intracerebral hemorrhage in full-term neonatal infants].
Intracranial hemorrhage in neonatal infants is mostly noted in the subependymal or subdural space. The former is characteristically noted in premature infants and is attributed to hemorrhage from the subependymal germinal matrix layer. The latter is prevalently noted in full-term neonatal infants and is thought to be associated with injury in the vicinity of the falx cerebri or tentorium cerebelli. We report two cases of intracerebral hemorrhage, which is relatively rare in full-term neonatal infants. In both of them hematoma was located in the left frontal area adjacent to the coronal suture. Angiogram did not reveal any causative abnormality. From CT scan and intraoperative findings it is speculated that the hemorrhage was caused by moulding at the coronal suture. In other words, moulding made the frontal bone slipped in beneath the parietal bone at the coronal suture causing pressure over the brain. The hemorrhage is thought to be caused by contusion of fragile vasculature of neonatal infants.
