Patient
male, 56 year(s)
 
 
  • Figure 1
    Ultrasound

    Ultrasound of LMS of the greater saphenous vein. The tumour is heterogeneous and irregularly vascularised (Doppler signal to the upper right corner). The Doppler signal in the upper left corner is the vein.

     
    Area of Interest: Extremities; Musculoskeletal system; Imaging Technique: Ultrasound; Ultrasound-Colour Doppler; Procedure: Diagnostic procedure; Special Focus: Epidemiology; Neoplasia; Tissue characterisation;
     
     
  • Figure 2
    MRI axial
     

    MR (T1 pre-contrast): The subcutaneous tumour is hypointense with almost the same intensity as muscle tissue. Note that the tumour is not invasive to the surrounding fat and muscle tissue.

     
    Area of Interest: Musculoskeletal soft tissue; Imaging Technique: MR; Procedure: Imaging sequences; Special Focus: Neoplasia;

    MRI (T1 fs after gadolinium administration): The tumour is now seen with heterogeneous enhancement.

     
    Area of Interest: Musculoskeletal soft tissue; Imaging Technique: MR; Procedure: Imaging sequences; Special Focus: Neoplasia;

    MR (TIRM): On this sequence the tumour is heterogeneous and hyperintense.

     
    Area of Interest: Musculoskeletal soft tissue; Imaging Technique: MR; Procedure: Imaging sequences; Special Focus: Neoplasia;

    MR (T1 after gadolinium administration): The image shows the heterogeneous hyperintense tumour in subcutis. Caudally the tumour seems to grow intraluminally in the vein.

     
    Area of Interest: Extremities; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Neoplasia;

    MR (T1 after gadolinium administration)

     
    Area of Interest: Extremities; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Neoplasia;

    MR (T1 after gadolinium administration): Cranially, the vein continues its course away from tumour.

     
    Area of Interest: Extremities; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Neoplasia;
     
     
  • Figure 4
    PET-CT

    PET-CT: The tumour is PET positive and localised, as shown in the image.
