Patient
male, 47 year(s)
 
 
  • Figure 1
    Sagittal reformatted CT image of the lumbar spine

    Note osteolysis in the sacral bone (asterisk).

     
    Area of Interest: Musculoskeletal spine; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Neoplasia;
     
     
  • Figure 2
    Sagittal T1-weighted image

    The lesion involves 4 sacral segments and is isointense to muscle. Note presacral extension (arrows).

     
    Area of Interest: Musculoskeletal spine; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Neoplasia;
     
     
  • Figure 3
    Sagittal T2-WI

    The lesion is of heterogeneous signal, containing low SI foci and high SI areas (consisting with necrosis or cystic changes) (arrows).

     
    Area of Interest: Musculoskeletal spine; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Neoplasia;
     
     
  • Figure 4
    Axial fat suppressed T2-WI

    The mass is of heterogeneous signal, containing low SI foci and high SI areas (consistent with necrosis or cystic changes) (asterisk).

     
    Area of Interest: Musculoskeletal spine; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Neoplasia;
     
     
  • Figure 5
    Sagittal T1-WI after IV administration of Gadolinium contrast

    There is heterogeneous enhancement of the lesion. The solid portions of the lesion enhance, whereas the cystic parts (arrows) show no enhancement.

     
    Area of Interest: Musculoskeletal spine; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Neoplasia;
     
     
  • Figure 6
    Sagittal T1-WI after 1 year.

    MRI after 1 year shows slight enlargement of the presacral component (arrow). Also note the enlarged, neurogenic bladder (asterisk).
