MRI Brain - Axial T1 pre and post-gadolinium - Glioma

  • The pre-gadolinium image shows indistinct distortion of grey and white matter in the left cerebral hemisphere posteriorly
  • The post-gadolinium image (overlay image) shows enhancement of this area
  • Central low signal in the enhanced area represents necrosis
  • Mass effect is indicated by shift of the mid-line structures – the septum pellucidum, a membrane which separates the lateral ventricles, is pushed to the right
  • This was an isolated lesion in the brain and was found to be a high-grade glioblastoma multiforme on biopsy – the most aggressive type of glioma
