GAMUT D-81-S1
RADIOLOGIC CRITERIA SUGGESTING MALIGNANT BONE NEOPLASM


1. Bone destruction (esp. moth-eaten or permeative, but may be geographic - particularly with wide transition zone 1C margin) (See D-61-S1, D-61-S2)
2. Irregular ill-defined margins of lesion ("wide transition zone" between normal and abnormal bone)
3. Cortical erosion or destruction
4. Codman triangle
5. Periosteal lamellation ("onion skin")
6. Periosteal right angle spiculation ("sunburst" or "hair-on-end")
7. Soft tissue mass adjacent to bone destruction
8. Chondroid or osteoid matrix (esp. in extraosseous tissues)
9. Metastasis to distant site
