Patient
female, 54 year(s)
 
 
  • Figure 1
    CT examination

    CT examination shows an isodense suprasellar mass involving the third ventricle.

     
    Area of Interest: Neuroradiology brain; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Neoplasia;
     
     
  • Figure 2
    MRI of the brain. Sagtital and coronal T1WI.
     

    Sagittal T1 reveals a solid, polylobulated, slightly heterogeneous and predominantly isointense mass centered on the third ventricle anterior recess.

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

    Coronal T1 shows the displacement of the floor of the third ventricle.

     
    Area of Interest: Neuroradiology brain; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Neoplasia;
     
     
  • Figure 3
    MRI of the brain. Coronal T2WI and axial FLAIR.
     

    Coronal T2 shows the hyperintense mass with perilesional vasogenic oedema.

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

    Axial FLAIR image shows the hyperintense mass with perilesional vasogenic oedema

    After paramagnetic contrast intravenous injection, the lesion demonstrated intense enhancement.

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

    After paramagnetic contrast intravenous injection, the lesion demonstrated intense enhancement.

  • Figure 5
    MRI of the brain. Axial DWI and corresponding ADC image.
     

    Axial DWI with high b-value. No diffusion restriction is demonstrated.

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

    ADC map. No diffusion restriction is demonstrated.

     
    Area of Interest: Neuroradiology brain; Imaging Technique: MR-Diffusion/Perfusion; Procedure: Diagnostic procedure; Special Focus: Neoplasia;
     
     
  • Figure 6
    CBV map of perfusion MRI

    Perfusion imaging using T2*-weighted gradient-echo sequence shows no significant increase of relative cerebral brain volume (rCBV).
