  • Figure 1
    Sagittal FSE T1Wi

    Sagittal image shows small subtle low SI lesion at the level of T11 (arrow).

     
    Area of Interest: Musculoskeletal spine; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Neoplasia;
     
     
  • Figure 2
    Sagittal FSE T2 Wi
     

    Full spine sagittal T2 FSE Wi shows an eccentric high SI lesion surrounded by a low SI rim and with important high SI medullary oedema.

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

    Sagittal FSE T2Wi more lateral plane shows the eccentric location of the lesion.

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

    Focalized sagittal T2 FSE Wi shows an eccentric high SI lesion surrounded by a low SI rim (arrowheads) and with important high SI medullary oedema (arrows).

     
    Area of Interest: Spine; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Neoplasia;
     
     
  • Figure 3
    Axial planes
     

    Axial FSE T1Wi low SI lesion is seen in the antero-lateral right side of the cord.

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

    Axial FSE T2Wi shows the high SI eccentric right anterolateral lesion (arrow). The rest of the cord shows increased SI.

     
    Area of Interest: Musculoskeletal spine; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Neoplasia;
     
     
  • Figure 4
    Sagittal FSE fat saturation T1 Wi
     

    Full spine sagittal fat saturation FSE T1Wi after Gd injection demonstrates important thick rim enhancement of the lesion improving its delimitation and the relation with the spinal cord, intra-extramedullary lesion.

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

  • Figure 5
    Axial FSE T1 post-gadolinium

    Axial fat saturation FSE T1Wi shows better the rim enhancement and the eccentric location of the lesion being predominantly intramedullary with an extramedullary component.
