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:
- 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
