  • Figure 1
    US

    US shows an epitrochlear oval hypoechoic mass with a hyperechoic hilum(star) with hyperechogenic periganglionar fat(circle). There is an area that shows marked focal lobular thickening, with small areas very...

     
    Area of Interest: Musculoskeletal soft tissue; Imaging Technique: Ultrasound; Procedure: Diagnostic procedure; Special Focus: Infection;
     
     
  • Figure 2
    Color Doppler

    Color Doppler study showing hyperemia of the hilum.

     
    Area of Interest: Musculoskeletal soft tissue; Imaging Technique: Ultrasound; Procedure: Diagnostic procedure; Special Focus: Infection;
     
     
  • Figure 3
    Axial T1WI

    Soft tissue subcutaneous mass mildy hyperintense to muscle (arrow), located in the medial margin of the elbow.

     
    Area of Interest: Musculoskeletal soft tissue; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Infection;
     
     
  • Figure 4
    Axial T2WI spair

    Soft tissue subcutaneos mass mildy hyperintense to muscle (arrow), located in the medial margin of the elbow. The hipointense central area corresponds to the hilum.

     
    Area of Interest: Musculoskeletal soft tissue; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Infection;
     
     
  • Figure 5
    Axial T1-weighted gadolinium-enhanced, fat-saturated

    The mass enhances homogeneously and presents inflammatory changes in the surrounding subcutaneous tissue.
