Overview
X Ray
X ray add valuable information in the initial evaluation of Ewing sarcoma.The appearance of these tumors is very variable, but usually have aggressive appearance. Common findings include:
- 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.

X-Ray of a child with Ewing's sarcoma of the tibia -
Radiograph demonstrates classic sunburst pattern of periosteal reaction.
Chest X Ray
X ray chest may be done to see if the cancer has spread to lungs.
