X Ray

Conventional radiography continues to play an important role in diagnosis. Typical appearances of conventional high grade osteosarcoma include:

• 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.
