Codman triangle
Codman triangle is a subperiosteal area of newly formed reactive bone that develops due to the lifting of the periosteum by an aggressive bone lesion. It can be seen in neoplastic conditions (osteosarcoma, Ewing sarcoma, chondrosarcoma) as well as in infectious processes (osteomyelitis, subperiosteal abscess).
