Overview
On x rays, enchondroma is characterized by lytic lesions that contain calcified chondroid matrix.[1] On x rays, periosteal chondroma is characterized by matrix calcification with ring and arc pattern and saucerisation of the adjacent bony cortex with a sclerotic periosteal reaction.[2]
X Ray Findings
- An x-ray may be helpful in the diagnosis of chondroma. Findings on an x-ray suggestive of chondroma include:
- Well-defined or sclerotic border
- Sharp zone of transition
- Small size or multiple lesions
- Confinement by natural barriers
- Lack of destruction of the cortex
- Lack of extension into the soft tissue
- Following x-ray findings are suggestive of more aggresive lesion:
- Poor definition
- Cortical destruction ("moth-eaten" or permeative pattern)
- Spiculated or interrupted periosteal reaction
- Extension into the soft tissue
- Large size
- X-ray findings of each subtype are mentioned as followings:
- Osteoid osteoma
- Small, round lucency (nidus) with a sclerotic margin
- Osteoblastoma
- Similar to osteoid osteoma but is usually larger (>2 cm in diameter)
- Rarely extend into the soft tissues
- Osteochondroma and hereditary multiple osteochondromas
- Bony spur (sometimes large) that arises from the surface of the cortex and usually points away from the joint
- Enchondroma
- Oval, well-circumscribed, central lucent lesion, with or without matrix calcifications
- May be expansion of the surrounding cortex, especially when the lesion is in the hand or foot
- Periosteal chondroma
- Small, scalloped, radiolucent lesions on the outer surface of the cortex in the metaphysis or diaphysis
- Rim of sclerotic bone
- Calcification
- Chondroblastoma
- Small, well-defined lesions with a sclerotic border that may cross the physis (growth plate)
- Chondromyxoid fibroma
- Eccentric, intramedullary, lobulated or bubbly lesion in the metaphysis
- Fibrous dysplasia
- Lytic lesion in the metaphysis or diaphysis with a "ground glass" appearance
- Cortical bone is thinned with a scalloped, undulating pattern due to endosteal erosion
- Ossifying fibroma
- Lytic thinning of the diaphyseal cortical bone with interspersed sclerosis
- Anterior or anterolateral bowing
- Nonossifying fibroma
- Small, well-defined, eccentric, expansile, lytic lesions located in the metaphysis with scalloped sclerotic border
- Unicameral bone cyst
- Well-marginated cystic lesions of the metaphysis or metadiaphysis without reactive sclerosis
