Patient
male, 46 year(s)
 
 
  • Figure 1
    CT of the brain
     

    includes non-enhanced scan showing an ill-defined high-density mass in the left periventricular white matter, surrounded by mild edema.

     
    Area of Interest: unknown; Imaging Technique: CT of the brain;

    After contrast administration, the mass is intensely enhancing.

     
    Area of Interest: unknown; Imaging Technique: CT of the brain;
     
     
  • Figure 2
    Sagittal SET1-weighted MR-images of the brain
     

    before Gd-injection

     
    Area of Interest: unknown; Imaging Technique: Sagittal SET1-weighted MR-images of the brain;

    and after Gd-injection shows on A the lesion slightly hypointense relative to white matter and on B an intense, inhomogeneous enhancement.

     
    Area of Interest: unknown; Imaging Technique: Sagittal SET1-weighted MR-images of the brain;

    MR-images of the brain
     

    On axial TSET2-weighted

     
    Area of Interest: unknown; Imaging Technique: MR-images of the brain;

    sagittal TSET2-weighted MR-images of the brain, the signal intensity of the lesion is mixed, with a central hypointense component, while the periphery is hyperintense.
