Periventricular white matter hemorrhages were diagnosed by ultrasound in 9/376 (2.4%) of premature infants. The most frequent site of such a hemorrhagic event is the area immediately posterolateral to the trigone of the lateral ventricle. These bleedings probably represent hemorrhagic infarcts into areas of periventricular leukomalacia. Porencephalic cysts developed at 12/14 hemorrhagic sites. In 2 infants follow-up studies showed progressive brain necrosis exceeding the area of initial hemorrhage.
