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


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


Distant - Shows pulmonary metastases



Bone destruction and associated soft tissue mass



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.
