Introduction
Overview
Overview
On CT scan chondrosarcoma is characterized by matrix calcification, endosteal calcification, cortical breach, and heterogenous contrast enhancement.
Computerized Tomography
Computerized Tomography
- CT scan confirms the x-ray findings.
- CT scan may be helpful in the diagnosis of chondrosarcoma. Findings on CT scan suggestive of chondrosarcoma 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.
