  • Figure 1
    Axial FLAIR

    Fluid-attenuated inversion recovery image demonstrates a large right intra-axial temporal mixed lesion, cystic and solid. It is surrounded by vasogenic oedema and is collapsing the right left.

     
    Area of Interest: Neuroradiology brain; Imaging Technique: MR; Special Focus: Neoplasia;
     
     
  • Figure 2
    Coronal T2

    T2-weighted image demonstrates large cystic and solid components and their mass effect over the brainstem and III ventricle walls.

     
    Area of Interest: Neuroradiology brain; Imaging Technique: MR; Special Focus: Neoplasia;
     
     
  • Figure 3
    Axial T1 Gad+

    T1-weighted post-contrast image showing an avidly enhancing solid component. It also exhibits a thin enhancement of the walls of the cyst.

     
    Area of Interest: Neuroradiology brain; Imaging Technique: MR; Special Focus: Neoplasia;
     
     
  • Figure 4
    DWI

    DWI image demonstrating no diffusion restriction of the tumour.

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

    Spectroscopy

    Proton MR spectroscopy using single voxel technique shows elevated choline peak, reduced NAA peak and elevation of Cho/Cr e Cho/NAA ratios.

     
    Area of Interest: Neuroradiology brain; Imaging Technique: MR-Spectroscopy; Special Focus: Neoplasia;
     
     
  • Figure 6
    Perfusion rCBV

    Perfusion-weighted imaging relative cerebral blood volume map shows increased values over the tumour area.
