Overview
Enchondroma must be differentiated from low-grade chondrosarcoma, fibrocartilaginous dysplasia, bone islands and bone infarcts. Periosteal chondroma must be differentiated from juxtacortical 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
- Fibrocartilaginous dysplasia
- Fibrous dysplasia with an extensive cartilagenous differentiation resulting in a picture that mimics enchondroma. Cellular atypia in the surrounding stroma in fibrocartilagenous dysplasia helps in the differentiation.[4]
- Bone islands[5]
- Small focus of compact bone within the cancellous bone.
- There is no cortical destruction or involvement of the surrounding soft tissues.
- Bone infarcts
- Differentiating an enchondroma from a bone infarct on plain film may be difficult. An enchondroma usually causes endosteal scalloping while an infarct will not. An infarct usually has a well-defined, sclerotic serpentine border, while an enchondroma does not.[6]
Periosteal chondroma must be differentiated from the following:
- Juxtacortical chondrosarcoma
- Periosteal osteosarcoma
