Overview
Bone CT may be helpful in the diagnosis of chondroma. Findings on CT suggestive of chondroma include chondroid calcifications, mild endosteal scalloping, and expansion of the overlying cortex with no cortical invasion, unless fractured.[1]
CT Scan
- Bone CT scan may be helpful in the diagnosis of enchondroma. Findings on CT scan suggestive of enchondroma include:
- Sharply defined scalloped margins: may have mild endosteal scalloping
- Expansion of the overlying cortex may be present, but there should not be cortical breakthrough unless fractured
- No periosteal reaction
- No soft tissue mass
