Chondroma x ray

Findings on an x-ray suggestive of chondroma include well-defined or sclerotic border, sharp zone of transition, confinement by natural barriers, lack of destruction of the cortex and lack of extension into the soft tissue.

• X-ray may be helpful in the diagnosis of chondroma. Findings on an x-ray suggestive of chondroma include:^{[1][2][3][4][5][6]}

• • 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

• 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

• Small, scalloped, radiolucent lesions on the outer surface of the cortex in the metaphysis or diaphysis
• Rim of sclerotic bone
• Calcification
