  • Figure 1
    T2W/FLAIR images of dysplastic gangliocytoma
     

    Axial FLAIR image showing the laminated pattern due to alternating hyperintense and isointense bands of tissue.

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

    Axial T2W image showing a large lesion occupying nearly the entire left cerebellar hemisphere extending to the vermis and compressing the fourth ventricle.

     
    Area of Interest: Neuroradiology brain; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Neoplasia;
     
     
  • Figure 2
    Gadolinium-enhanced T1W images of dysplastic gangliocytoma
     

    Axial gadolinium-enhanced T1W image showing striated laminated alternating hypointense and isointense bands of tissue. The vessels are delineated, but there is no true enhancement.

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

    Sagittal gadolinium-enhanced T1W image showing striated laminated alternating hypointense and isointense bands of tissue. The vessels are delineated, but there is no true enhancement.

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

    Coronal gadolinium-enhanced T1W image showing striated laminated alternating hypointense and isointense bands of tissue. The vessels are delineated, but there is no true enhancement.

     
    Area of Interest: Neuroradiology brain; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Neoplasia;
     
     
  • Figure 3
    DWI/ADC images of dysplastic gangliocytoma
     

    Isotropic diffusion weighted image (b-value: 0) of the lesion.

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

    Isotropic diffusion weighted image (b-value: 1000) shows high signal of the lesion due to the T2-shine through effect.

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

    The lesion appears isointense to the cerebellar parenchyma in ADC map.
