Table 1 List of clinical and imaging features used in the differential diagnosis between enchondroma and chondrosarcoma
From: The role of magnetic resonance imaging in the evaluation of bone tumours and tumour-like lesions
Enchondroma | Chondrosarcoma |
|---|---|
More common in extremities | More common in the axial skeleton |
No pain (only if associated with fracture) | Can cause pain |
No periostitis | Can have associated periostitis |
No growth beyond skeletal maturity | Rapid growth, regardless of the skeletal maturity |
No soft tissue component | Associated focal cortical thickening |
Absence of bone oedema | Different patterns of signal intensity |
Size usually ≤4 cm | Bone destruction |
| Â | Loss of calcifications on follow-up |
| Â | Soft tissue component |
| Â | Bone marrow oedema |
|  | Size usually >4 cm |
