Patient
male, 8 year(s)
 
 
  • Figure 1
    Preoperative MRI
     

    Coronal STIR image: the right sciatic nerve is normal in size.

     
    Area of Interest: Neuroradiology peripheral nerve; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Hyperplasia / Hypertrophy;

    Axial STIR image: the right sciatic nerve is not enlarged.

     
    Area of Interest: Neuroradiology peripheral nerve; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Hyperplasia / Hypertrophy;
     
     
  • Figure 2
    MRI at 3 months after right femoral amputation
     

    Coronal STIR image: Hypertrophy of the right sciatic nerve seen as a tubular hyperintense structure from the transection site to the proximal femoral level.

     
    Area of Interest: Neuroradiology peripheral nerve; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Hyperplasia / Hypertrophy;

    Axial STIR image: Enlarged right sciatic nerve.

     
    Area of Interest: Neuroradiology peripheral nerve; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Hyperplasia / Hypertrophy;
     
     
  • Figure 3
    MRI at 6 months after right femoral amputation
     

    Coronal STIR image: Hyperintense hypertrophic sciatic nerve. The right sciatic nerve seems thicker than at 3-month control.

     
    Area of Interest: Musculoskeletal soft tissue; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Hyperplasia / Hypertrophy;

    Axial STIR image: Hyperintense hypertrophic sciatic nerve. The right sciatic nerve seems thicker than at 3-month control.
