male, 70 year(s)
 
 
  • Figure 1
    Abdominal US

    Longitudinal sonogram of right lower quadrant shows a cystic mass with posterior enhancement measuring 81x53x50 mm. Heterogeneous echogenic material is present in the posterior region.

     
    Area of Interest: unknown; Imaging Technique: Abdominal US;
     
     
  • Figure 2
    Spiral CT findings
     

    Unenhanced axial scan. Well-encapsulated cystic mass.

     
    Area of Interest: unknown; Imaging Technique: Spiral CT findings;

    Axial scan after i.v. contrast injection. Cystic mass with regularly enhanced wall.

     
    Area of Interest: unknown; Imaging Technique: Spiral CT findings;

    Enhanced axial scan. The density of the material localized on lower portion of the cyst was not modified by intravenous injection of contrast medium.

     
    Area of Interest: unknown; Imaging Technique: Spiral CT findings;

    Mulitplanar recostructions (MIP algorithm). The recostruction illustrates the extent of cystic mass localized in the anatomical region of the appendix.

     
    Area of Interest: unknown; Imaging Technique: Spiral CT findings;

    Mulitplanar recostruction (MIP algorithm). The caecum and ascendent colon are displaced, while the right kidney is well differentiated from the mass.
