Basal ganglia herniation into the fourth ventricle

Abstract

Background: Transtentorial herniation of large cerebral fragments is a rare phenomenon. Method: 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. Conclusion: Sufficiently rapid intracerebral bleeding can dissect fragments of cerebrum and displace them long distances across the tentorial opening.
