Overview
Enchondroma must be differentiated from low-grade chondrosarcoma, fibrocartilaginous dysplasia, bone islands and bone infarcts. Periosteal chondroma must be differentiated from juxtacortical chondrosarcoma, osteochondroma and periosteal osteosarcoma.
Differential Diagnosis
Enchondroma must be differentiated from the following:[1][2][3][4][5]
- 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
Periosteal chondroma must be differentiated from the following:[6][7][8][9]
Periosteal chondrosarcoma
- Chondrosarcomas are generally greater in size and occur in older patients more than 50 years of age.
- They may extend into the soft tissue.
- Periosteal chondrosarcoma shows popcorn calcifications on radiographs, which present as a collection of scalloped radiolucencies and with a sclerotic margin.
Periosteal osteosarcoma
- Periosteal osteosarcomas are slow-growing, and primarily arise beneath the periosteum, inducing new bone formation.
- It seen as a radiolucent lesion on the bone surface with perpendicular striae and a peripheral Codman’s triangle on radiography.
Osteochondroma
- Osteochondromas are more commonly seen in adolescents, in contrast with periosteal chondromas, which typically occur in young adults.
- Osteochondromas may also be distinguished by the presence of a dense osteoid formation in the cortex and medulla of the mass, and by the continuation with its originating bone.
