    First lesion
     

    T2-weighted sagittal image shows homogeneous intradural extramedullary hyperintensity tumour to cord.

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

    T1-weighted sagittal image demonstrates a homogeneous, well-circumscribed, myxopapillary ependymoma, which is isointense to cord.

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

    Contrast enhanced sagittal T1-weighted MR image demonstrates a intradural extramedullary well-circumscribed oval mass with intense enhancement.

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

    Axial T1-weighted MR image reveals a homogeneous, well-circumscribed lesion isointense to cord.

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

    Contrast-enhanced axial T1-weighted MR image reveals a eccentric location of the enhancing mass intradural extramedullary ependymoma.

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

    Second lesion
     

    T1-weighted sagittal image demonstrates a myxopapillary ependymoma, which is isointense to cord at L2-L3. It shows an inferior component hyperintense due to a mixoid or haemorrhage intratumoral component.

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

    T2-weighted sagittal image shows extramedullary heterogenous tumour at L2-L3 level

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

    Contrast-enhanced sagittal T1-weighted MR image demonstrates intradural extramedullary mass with intense enhancement at conus. In the inferior margin shows less enhacement due to the presence of haemorrhage.

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

    Axial T2-weighted image reveals intradural extramedullary tumour at filum terminale that shows low-signal at the tumour margin because of haemorrhage.

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

    Contrast-enhanced axial T1-weighted MR image show intradural extramedullary enhancing mass at conus, with a heterogeneous enhancement pattern due to haemorrhage intratumoral component.
