Patient
female, 40 year(s)
 
 
  • Figure 1
    CT with and without IVC
     

    Axial unenhanced CT showing small, well-circumscribed, intraventricular mass located in the left lateral ventricle, affiliated with monoventricular dilatation.

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

    Axial contrast-enhanced CT shows a moderately enhancing, small, well-circumscribed, intraventricular mass located in the left lateral ventricle, affiliated with monoventricular dilatation.

     
    Area of Interest: Neuroradiology brain; Imaging Technique: CT; Procedure: Contrast agent-intravenous; Special Focus: Neoplasia;

    Sagittal unenhanced CT showing small, well-circumscribed, intraventricular mass located in the left lateral ventricle, affiliated with monoventricular dilatation.

     
    Area of Interest: Neuroradiology brain; Imaging Technique: CT; Procedure: Contrast agent-intravenous; Special Focus: Neoplasia;

    MRI
     

    Sagittal T1 sequence shows an isointense mass and the ipsilateral ventricle is clearly enlarged.

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

    Axial contrast-enhanced T1 3D sequence shows an isointense mass and slight enhancement.

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

    Axial T2 slice shows small isointense mass and monoventricular dilation. Increased T2 signal intensity is seen in the adjacent periventricular white matter.

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

    Sagittal FIESTA (balanced steady-state gradient echo sequence) slice shows small isointense mass and monoventricular dilation.

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

    Axial T2 gradient image shows a small hypointense area within the intraventricular mass, compatible with calcification.

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

    B1000 and ADC images show restricted diffusion in the left intraventricular mass.

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