  • Figure 1
    Ultrasound abdomen axial section just below the umbilicus

    Ultrasound image shows a 5x4.5 cm size mixed heterogeneous well-defined lesion in the right paraspinal region. The lesion displaces the right psoas muscle (outlined by white arrows) anteromedially.

     
    Area of Interest: Abdomen; Neuroradiology peripheral nerve; Imaging Technique: Ultrasound; Procedure: Diagnostic procedure; Special Focus: Neoplasia;
     
     
  • Figure 2
    High resolution Ultrasound colour Doppler of the lesion

    High resolution colour Doppler scan shows that the lesion is well defined, mildly heterogeneous and with internal vascularity.

     
    Area of Interest: Abdomen; Neuroradiology peripheral nerve; Imaging Technique: Ultrasound-Colour Doppler; Procedure: Diagnostic procedure; Special Focus: Neoplasia;
     
     
  • Figure 3
    Serial ultrasound images showing exiting nerve root at L3 vertebra

    Exiting spinal nerve root at L3 vertebra level (white arrows). A well-defined mixed heterogeneous lesion (white star) is seen arising eccentrically from the spinal nerve root, displacing the right psoas muscle...

  • Figure 4
    Coronal section non-contrast CT abdomen

    Coronal plain CT image shows a well-defined homogeneous soft tissue density lesion in continuity with the nerve root. Absent right kidney is noted.

  • Figure 5
    Serial sagittal plain CT images showing exiting spinal nerve root

    A well-defined soft tissue density lesion (white star) in right paraspinal region arises eccentrically from the exiting nerve root at L3 vertebra (white arrows). The lesion displaces the right psoas muscle (gray...

  • Figure 6
    Coronal T2 weighted MR image

    Coronal T2 weighted MR image shows a well defined heterogeneously hyperintense lesion with peripheral hypointense rim arising from exiting nerve root at L3 vertebra.

Exiting spinal nerve root at L3 vertebra level (white arrows). A well-defined mixed heterogeneous lesion (white star) is seen arising eccentrically from the spinal nerve root, displacing the right psoas muscle (vertical gray arrows).
 
Coronal plain CT image shows a well-defined homogeneous soft tissue density lesion in continuity with the nerve root. Absent right kidney is noted.
 
A well-defined soft tissue density lesion (white star) in right paraspinal region arises eccentrically from the exiting nerve root at L3 vertebra (white arrows). The lesion displaces the right psoas muscle (gray arrow) anteriorly.
 
Coronal T2 weighted MR image shows a well defined heterogeneously hyperintense lesion with peripheral hypointense rim arising from exiting nerve root at L3 vertebra.
