  • Figure 1
    Ultrasound
     

    Ultrasound images of the Rt. forearm abscess (red arrows). Transverse scan (left) and oblique scan (right).

     
    Area of Interest: Musculoskeletal soft tissue; Imaging Technique: Ultrasound; Procedure: Abscess delineation; Special Focus: Abscess;

    Ultrasound images of the Lt. thigh abscess (red arrows). Longitudinal scan (left) and surrounding muscles (transverse scan on right).

     
    Area of Interest: Musculoskeletal soft tissue; Imaging Technique: Ultrasound; Procedure: Abscess delineation; Special Focus: Abscess;
     
     
  • Figure 2
    Left thigh MRI
     

    Axial T2 MR image of the left hip revealing diffuse oedema of all muscles surrounding the left hip joint (red arrows).

     
    Area of Interest: Musculoskeletal joint; Musculoskeletal soft tissue; Imaging Technique: MR; Procedure: Abscess delineation; Special Focus: Abscess;

    Axial T2 image revealing synovial thickening (red arrow), effusion, subluxation of the femoral head laterally and muscle oedema in the adjacent part of rectus femoris.

     
    Area of Interest: Musculoskeletal joint; Musculoskeletal soft tissue; Imaging Technique: MR; Procedure: Abscess delineation; Special Focus: Abscess;

    Axial T2 image. All muscles around the Lt. Femur show diffuse oedema (red arrows), with a small abscess cavity anteriorly (yellow arrow).

     
    Area of Interest: Musculoskeletal joint; Musculoskeletal soft tissue; Imaging Technique: MR; Procedure: Abscess delineation; Special Focus: Abscess;

    Coronal STIR image. Fine erosions are noted in the roof of the acetabulum (red arrow). Femoral head reveals deformity of its contour (yellow arrow).

     
    Area of Interest: Musculoskeletal joint; Musculoskeletal soft tissue; Imaging Technique: MR; Procedure: Abscess delineation; Special Focus: Abscess;
     
     
  • Figure 3
    Right forearm MRI
     

    Coronal STIR MR images of the right forearm. The abscess cavity (red arrow) on the antero-lateral aspect of the forearm, associated with extensive subcutaneous oedema.

     
    Area of Interest: Musculoskeletal joint; Musculoskeletal soft tissue; Imaging Technique: MR; Procedure: Abscess delineation; Special Focus: Abscess;

    Bone marrow oedema is noted along the entire length of the radius and ulna (red arrows) and also in the interosseous muscles (yellow arrow).

     
    Area of Interest: Musculoskeletal joint; Musculoskeletal soft tissue; Imaging Technique: MR; Procedure: Abscess delineation; Special Focus: Abscess;

    The infection extends to the antecubital fossa (red arrow), where there is another smaller abscess that is separate from the first one.
