title: Basal ganglia herniation into the fourth ventricle.
abstract: BACKGROUND
  Transtentorial herniation of large cerebral fragments is a rare phenomenon.
  
  
  METHODS
  Case Study.
  
  
  RESULTS
  Examination of the brain of a 35-year-old male showed massive intracerebral hemorrhage resulting in displacement of basal ganglia components into the fourth ventricle.
  
  
  CONCLUSIONS
  Sufficiently rapid intracerebral bleeding can dissect fragments of cerebrum and displace them long distances across the tentorial opening.
