  • Figure 1
    Axial T2W MR

    Axial T2W image showing ill-defined hyperdense lesion involving the left thigh in the subcutaneous plane on anteromedial aspect. The femoral nerve was not seen separately from the mass lesion.

     
    Area of Interest: Musculoskeletal soft tissue; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Congenital;
     
     
  • Figure 2
    Axial T1W image

    Axial T1W image showing hypointense lesion within the subcutanoeus plane. Interspersed areas of fat component noted.

     
    Area of Interest: Soft tissues / Skin; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Epidemiology;

    Axial STIR Image

    Axial STIR image showing suppression of interveining fat of the lesion, whereas the lesion appears hyperintense. Underlying muscles appears hyperintense (oedema). Posteriorly soft tissue defect noted which was due...

  • Figure 4
    Coronal GRE image

    Coronal GRE image showing no evidence of blooming within the lesion. Underlying bone shows intact cortex. The femoral neural bundle is seen to be involved by the lesion.
