Overview

On x-ray, Ewing's sarcoma is characterized by a permeative lytic lesion, periosteal reaction, and soft tissue calcification.

X-Ray

X-ray add valuable information in the initial evaluation of Ewing's sarcoma.The appearance of these tumors is variable. Common x-ray findings are listed below:

  • A permeative lytic lesion in the metaphysis and diaphysis of the bone with a prominent soft tissue mass extending from the bone.
  • Periosteal reaction usually is present, and it often has an onionskin or sunburst pattern, which indicates an aggressive process.
  • Codman triangle may be present at the margins of the lesion. These result from the elevation of the periosteum and central destruction of the periosteal reaction caused by the tumor.
  • The wide zone of transition (e.g. permeative) is the most useful plain film characteristic in differentiation of benign versus aggressive or malignant lytic lesions.
  • Soft tissue calcification is uncommon, seen in less than 10% of cases.
