  • Figure 1
    Sagittal T1W and T2W image without contrast
     

    Sagittal T1W image without contrast shows lesion in the cord at T2-T3 level which is isointense to CSF.

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

    Sagittal T2W image shows lesion which is iso to hypointense.

     
    Area of Interest: Neuroradiology spine; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Neoplasia;
     
     
  • Figure 2
    Axial pre and post-contrast T1W and T2W.
     

    Axial T2W shows an intradural and intramedullary lesion which is hyperintense on T2W.

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

    Axial T1W shows an intradural and intramedullary lesion which is hypointense on T1W.

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

    Axial post-contrast image shows iso-intense lesion with no post-contrast enhancement.
