Overview
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.
- X-rays, which can show the location, size, and shape of a bone tumor. Even if x-rays suggest that an abnormal area is benign, especially if the patient is experiencing unusual or persistent pain.
