Patient
female, 32 year(s)
 
 
  • Figure 1
    Abdominal MRI
     

    Axial unenhanced T1- (a) and T2-weighted (b) images. Roundish lesion measuring 2,5 cm, abutting the distal descending colon, and consisting of a hyperintense fatty center with peripheral soft tissue rim.

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

    Axial unenhanced T1- (a) and T2-weighted (b) images. Roundish lesion measuring 2,5 cm, abutting the distal descending colon, and consisting of a hyperintense fatty center with peripheral soft tissue rim.

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

    Unenhanced fat suppressed (SPIR) T1-weighted image. Signal loss in the central portion of the pericolonic lesion, confirming its fatty content.

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

    Post-contrast fat suppressed (SPIR) T1-weighted image. Peripheral rim enhancement consistent with inflammation involving the pericolonic lesion and mild inflammatory stranding in the surrounding fat planes.

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

    Abdominal CT

    Focused CT acquisition confirming the MR findings: pericolonic lesion with peripheral soft tissue, adipose center, and mild stranding of surrounding fat planes.
