Periventricular Hemorrhage

  • Etiology: venous obstruction in periventricular white matter leads to hemorrhagic venous infarct in terminal vein which usually becomes cystic (venous event -> hemorrhagic venous infarct) = venous wet infarct
  • Imaging: unilateral or asymmetric periventricular echogencities
  • Complications: cystic encephalomalacia
