  • Figure 1
    Axial CT

    Axial CT image showing a large heterogeneous mass in the right frontoparietal region with hypodense centre and surrounding oedema.

     
    Area of Interest: Neuroradiology brain; Imaging Technique: CT; Procedure: Diagnostic procedure; Special Focus: Neoplasia;
     
     
  • Figure 2
    Axial T1-weighted images
     

    Axial T1-weighted image shows an iso to hypointense lesion in the right frontoparietal region.

     
    Area of Interest: Neuroradiology brain; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Neoplasia;

    Enhanced axial T1-weighted image demonstrates thick-walled ring enhancement.

  • Figure 3
    Glial and sarcomatous elements
     

    Axial T2-weighted image shows a heterogeneous lesion with hyper and hypointense nodular elements. The latter possibly correspond to the sarcomatous component.

     
    Area of Interest: Neuroradiology brain; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Neoplasia;

    Axial T2-FLAIR image shows the heterogeneous lesion and extensive perilesional oedema.

     
    Area of Interest: Neuroradiology brain; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Neoplasia;

    Axial enhanced T1-weighted image shows nodular enhancement of the solid sarcomatous components.

     
    Area of Interest: Neuroradiology brain; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Neoplasia;
     
     
  • Figure 4
    Strip enhancement
     

    Coronal enhanced T1-weighted image shows regional strip enhancement within the tumour.

     
    Area of Interest: Neuroradiology brain; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Neoplasia;

    Sagittal enhanced T1- weighted image shows intratumoral strip enhancement.

     
    Area of Interest: Neuroradiology brain; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Neoplasia;
