Overview
On x-ray, osteosarcoma is characterized by medullary and cortical bone destruction, periosteal reaction, tumor matrix calcification and soft tissue mass.[1]
X Ray
Conventional radiography continues to play an important role in diagnosis of osteosarcoma. Typical appearances of conventional high grade osteosarcoma include:[1]
- Medullary and cortical bone destruction.
- Wide zone of transition, permeative or moth-eaten appearance.
- Aggressive periosteal reaction characterized by:
- Sunburst appearance
- Codman triangle
- Lamellated (onion skin) reaction: less frequently seen
- Soft-tissue mass.
- Tumor matrix ossification/calcification.
- Variable: reflects a combination of the amount of tumor bone production, calcified matrix, and osteoid.
- Ill-defined fluffy or cloud-like cf. to the rings and arcs of chondroid lesions.
