  • Figure 1
    Abdominal ultrasound at level of mid aorta

    Transverse and longitudinal ultrasound at level of mid aorta reveals the presence of a preaortic and paraaortic hypoechoic soft tissue mass. The aortic artery has a normal size.

     
    Area of Interest: Abdomen; Imaging Technique: Ultrasound; Procedure: Diagnostic procedure; Special Focus: Inflammation;
     
     
  • Figure 2
    Axial IV C+ abdominal CT

    Low-attenuation mass anterior and lateral to the aorta. The mass does not cause anterior aortic displacement. Double inferior cava vein and left kidney agenesis are also seen. There is no hydronephrosis or hydroureter.

     
    Area of Interest: Abdomen; Imaging Technique: CT; Procedure: Diagnostic procedure; Special Focus: Inflammation;
     
     
  • Figure 3
    Axial reformatted contrast-enhanced MDCT image

    The images show a double inferior cava vein (Yellow arrows mark).

     
    Area of Interest: Abdomen; Imaging Technique: CT; Procedure: Diagnostic procedure; Special Focus: Inflammation;
     
     
  • Figure 4
    Coronal reformatted abdominal CT

    The yellow arrow marks the left proximal inferior cava vein. A soft tissue mass surrounding the aortic artery and left kidney agenesis are also seen.

     
    Area of Interest: Abdomen; Imaging Technique: CT; Procedure: Diagnostic procedure; Special Focus: Inflammation;
     
     
  • Figure 5
    Axial T2-weighted abdominal MRI (SSFSE)
     

    Retroperitoneal mass surrounding the aortic artery. The low signal intensity of this tissue suggests no active inflammation.

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

    After two months of corticoid therapy there is an important improvement in size of the retroperitoneal mass. Double inferior vena cava is better seen.

     
    Area of Interest: Abdomen; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Inflammation;
     
     
  • Figure 6
    Axial unhenhanced T1-weighted LAVA sequence MRI

    Mass around the aorta that has a signal intensity similar to muscle. There is no anterior displacement of the aorta.

     
    Area of Interest: Abdomen; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Inflammation;
     
     
  • Figure 7
    Axial contrast-enhancement fat-saturated T1-weighted LAVA sequence MRI (arterial phase)

    Soft-tissue mass circumferentially surrounding the aorta. There is absent contrast enhancement which suggests no active inflammation.

     
    Area of Interest: Abdomen; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Inflammation;
     
     
  • Figure 8
    Axial contrast-enhancement fat-saturated T1-weighted LAVA sequence MRI (venous phase)

    Absence soft-tissue enhancement after contrast administration, which indicates inactive disease.
