Overview
Enchondroma must be differentiated from low-grade chondrosarcoma, fibrocartilaginous dysplasia, bone islands and bone infarcts.[1][2][3][4][5] Periosteal chondroma must be differentiated from periosteal chondrosarcoma and periosteal osteosarcoma.
Differential Diagnosis
Enchondroma must be differentiated from the following:
- Low-grade chondrosarcoma
- When differentiating an enchondroma from a chondrosarcoma, the radiographic image may be equivocal. However, periostitis is not usually seen with an uncomplicated enchondroma.[1]
- Chondroblastoma
- Presence of bone marrow edema frequently seen surrounding chondroblastomas is helpful, as it is not a usual feature of chondromyxoid fibromas, giant cell tumors, or enchondromas.[2][3]
- Fibrocartilaginous dysplasia
- Bone islands[5]
- Small focus of compact bone within the cancellous bone
- No cortical destruction or involvement of the surrounding soft tissues
- Bone infarcts
Periosteal chondroma must be differentiated from the following:
- Periosteal chondrosarcoma
- Periosteal osteosarcoma
