Non-Neonatal Intraventricular Hemorrhage

  • Etiology: Trauma, anticoagulation, aneurysm rupture (anterior communicating artery), arteriovenous malformation
  • Imaging:
    — Blood within ventricular system
    — If etiology is uncertain perform MRI and MRA or CTA to look for vascular causes
  • DDX:
  • Complications: Communicating hydrocephalus
  • Treatment: May require ventriculoperitoneal shunt
  • Clinical:

Radiology Cases of Non-Neonatal Intraventicular Hemorrhage

Radiology Cases of Non-Neonatal Intraventicular Hemorrhage on Extracorporeal Membrane Oxygenation

CT of intraventricular hemorrhage, intracerebral hemorrhage, and cerebral atrophy in a patient on extracorporeal membrane oxygenation (ECMO)
Axial CT without contrast of the brain shows mixed-density fluid in the left lateral ventricle posteriorly and mixed-density fluid in the left parietal-occipital lobe. There is also diffuse prominence of the sulci and ventricular system.

Radiology Cases of Non-Neonatal Intraventicular Hemorrhage Post Traumatic

CT of subarachnoid hemorrhage, intraventricular hemorrhage and diffuse cerebral edema
Axial CT without contrast of the brain shows acute hemorrhage around the Circle of Willis and brainstem (left) and in the posterior horns of the lateral ventricles bilaterally (right). There is also loss of the cortical sulci and basilar cisterns.

Radiology Cases of Non-Neonatal Intraventicular Hemorrhage and Cephalohematoma After Birth Trauma

CT of cephalohematoma in a newborn
Coronal CT without contrast of the brain shows a high density fluid collection over the top of the left skull that does not cross suture lines. A large amount of high density fluid is seen in the anterior and temporal horns of the right lateral ventricle and there is dilation of the lateral ventricles.
