Neonatal intracranial hemorrhages usually occur during the first week of life. Late intracranial hemorrhages have rarely been reported. Seventeen infants were identified whose hemorrhages occurred after the first postpartum week. The latest hemorrhage occurred eight weeks postpartum. Most of the hemorrhages were small and restricted to the region of the germinal matrix. Sixteen of the infants were premature, with an estimated postconceptual age at the time of hemorrhage of 33 weeks or less.
新生儿颅内出血通常发生在出生后的第一周。迟发性颅内出血鲜有报道。已确定17例婴儿的出血发生在产后第一周之后。最晚的出血发生在产后八周。大多数出血面积较小，局限于生发基质区域。其中16例婴儿为早产儿，出血时估计孕龄为33周或更小。
