Overview
On CT scan chondrosarcoma is characterized by matrix calcification, endosteal calcification, cortical breach, and heterogenous contrast enhancement.
Computerized Tomography
- CT scan confirms the x-ray findings.
 |
- CT findings include:[1][2][3][4]
- Majority of the cases demonstrate matrix calcification.
- Endosteal calcification more easily identified on CT compared to radiographs.
- Cortical breach seen in 88% of long bone chondrosarcoma.
- Deep endosteal scalloping suggests chondrosarcoma instead of enchondroma.
- Soft tissue mass: density increases with increased grade of tumor due to increased cellularity.
CT Chest
- It is helpful to identify metastasis to the lung.
