Ewing Sarcoma

 

 

CT scan

 

In Ewing sarcoma (ES) CT scan can assess:

  • Extent of bone destruction and cortical disruption
  • Helps to plan biopsy 

 

 

CT Scan

Role

Local - Defines the extent of bone destruction and extra-osseous tumor

 

Distant - Shows pulmonary metastases

 

Appearance

Bone destruction and associated soft tissue mass

 

Limitations

Not sensitive to intramedullary tumor  extension

 

 

The CT scan below shows ES arising from the right scapula. There is cortical destruction (#1) and a mass can be seen between the right scapular spine and the trapezius.
