Patient
male, 59 year(s)
 
 
  • Figure 1
    Contrast CT
     

    Axial CT scan shows a well-defined mass in the right retroperitoneum with internal linear calcification.

     
    Area of Interest: Abdomen; Imaging Technique: CT; Procedure: Diagnostic procedure; Special Focus: Neoplasia;

    The same right retroperitoneal mass at slightly lower level.

     
    Area of Interest: Abdomen; Imaging Technique: CT; Procedure: Diagnostic procedure; Special Focus: Neoplasia;
     
     
  • Figure 2
    MRI
     

    T1-weighted axial image shows hypointense mass in the right retroperitoneum.

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

    On T2-weighted image the mass is slightly heterogeneous and hyperintense.

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

    Post-contrast arterial phase T1-weighted image shows minimal enhancement within the mass.

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

    During the portal venous phase there is further internal enhancement in the mass.

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

    Progressive internal enhancement is seen in the mass at 3 minute delayed image.

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

    Three minute delayed post-contrast coronal image depicts the enhancing curvilinear bands representing interlacing bundles of longitudinal and transverse Schwann cells or collagen fibres, highly suggestive of diagnosis...
