  • Figure 1
    Plain film of right thigh

    Plain film of right thigh. Note the higher density in external soft tissue of the thigh (yellow arrows), consistent with the presence of an expansive lesion. Marked atherosclerotic calcifications are also found...

     
    Area of Interest: Musculoskeletal soft tissue; Imaging Technique: Conventional radiography; Procedure: Diagnostic procedure; Special Focus: Trauma;
     
     
  • Figure 2
    Plain film of right thigh

    Plain film of right thigh - frontal view, with the soft tissue tumefaction (yellow arrows) and atherosclerotic calcifications (orange arrow).

     
    Area of Interest: Musculoskeletal soft tissue; Imaging Technique: Conventional radiography; Procedure: Diagnostic procedure; Special Focus: Trauma;
     
     
  • Figure 3
    Ultrasound image

    Ultrasound image shows a heterogeneous liquefied lesion. There is a small capsule around the lesion (green arrows).

     
    Area of Interest: Musculoskeletal soft tissue; Imaging Technique: Ultrasound; Procedure: Diagnostic procedure; Special Focus: Trauma;
     
     
  • Figure 4
    Ultrasound image

    Ultrasound image demonstrating the area of capsular rupture (blue arrows).

  • Figure 5
    T1-weighted image

    T1-weighted image in the coronal plane, showing a fusiform lesion, with a hypointense capsule (red arrows). The lesion has areas of different intensities, but predominantly with high intensity, according to the...

  • Figure 6
    T1-weighted image

    T1-weighted image with fat supression in the axial plane, showing a lesion, predominantly hyperintense, confirming its haemorragic nature (red arrows). The area of capsular rupture is also visible (blue arrow).
