Overview
Chest X-ray and chest CT scan: This plain x-ray and CT scan of your chest may be done to see if the cancer has spread to your lungs.
Images
- Both long and flat bones are affected.
- In the long bones, the tumor is almost always metaphyseal or diaphyseal.
- Most commonly, radiographs show a long, permeative lytic lesion in the metadiaphysis 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.
- In some patients, Codman triangles 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.
-

-
Radiograph demonstrates classic sunburst pattern of periosteal reaction.
