Neonatal Intraventricular Hemorrhage

  • Etiology: poor cerebral autoregulation, hypo-or hypertensive arterial event leads to germinal matrix hemorrhage (arterial event -> germinal matrix hemorrhage)
  • Imaging: Grade I is focal germinal matrix hemorrhage, Grade II is germinal matrix hemorrhage + intraventricular hemorrhage without ventricular dilation, Grade III is germinal matrix hemorrhage + intraventricular hemorrhage with ventricular dilation
  • Complications: communicating hydrocephalus from obstructed pacchionian granulations
