Overview
On x-ray, chondrosarcoma is characterized by lytic lesion, intralesional calcification, endosteal scalloping, and cortical remodeling.
X Ray
Views
- AP and lateral view of the affected bone is needed.
Findings
- An x-ray may be helpful in the diagnosis of chondrosarcoma. Findings on an x-ray suggestive of chondrosarcoma include: :[1][2][3][4]
- Lytic or blastic lesion
- Intralesional calcification classicaly called as popcorn calcification.
- Endosteal scalloping affecting more than two thirds of the cortical thickness
- Moth eaten appearance or permeative appearance in higher grade tumors.
- Cortical remodeling, thickening and periosteal reaction seen in mesenchymal chondrosarcoma.
- These findings are useful in distinguishing between an enchondroma and low grade chondrosarcoma.
- De-differentiated chondrosarcomas radiographically show a lower grade chondroid lesion with superimposed highly destructive area consistent with the high grade transformed dedifferentiated chondrosarcoma.
