  • Figure 1
    Photograph of the trunk and lower limbs

    Right lower limb overgrowth with brown skin macules in the right thigh.

     
    Area of Interest: Musculoskeletal system; Imaging Technique: Experimental; Procedure: History; Special Focus: Hyperplasia / Hypertrophy;
     
     
  • Figure 2
    X-ray of both legs

    Lower limbs discrepancy with mild medial bowing of the right tibial and fibular shafts and increased soft tissue density at the right leg.

     
    Area of Interest: Musculoskeletal bone; Imaging Technique: Conventional radiography; Procedure: Diagnostic procedure; Special Focus: Hyperplasia / Hypertrophy;
     
     
  • Figure 3
    MRI of both legs

    A- Coronal T2-weighted image shows a high signal soft tissue lesion in the posterior compartment of the right leg. B- Axial T2-weighted image shows the characteristic target sign within the mass (red arrows).

     
    Area of Interest: Musculoskeletal soft tissue; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Neoplasia;
     
     
  • Figure 4
    MRI of both legs

    A- Pre and B- Post-contrast administration coronal T1-weighted images show a minimally enhancing low to intermediate signal intensity mass of the right leg posterior compartment.
