  • Figure 1
    Brain MRI

    Axial, T2w-images reveal a large intraventricular mass (straight arrows). Cystic areas, with high signal intensity on T2w-images, are seen within the mass (curved arrows).

     
    Area of Interest: Neuroradiology brain; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Neoplasia;
     
     
  • Figure 2
    Brain MRI

    Axial, T1w-images after the iv contrast administration reveal the inhomogeneous enhancement of the mass (straight arrows). The cystic areas appear with low signal intensity (curved arrows).

     
    Area of Interest: Neuroradiology brain; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Neoplasia;
     
     
  • Figure 3
    Spectroscopy

    Spectrum analysis consists of high levels of choline, the presence of alanine as a doublet at 1.3 ppm and 1.5 ppm, absence of creatine and NAA, as well as increased levels of glutathione, glutamine and glutamate.
