Which sarcoma does not display the radiographic feature of Codman’s triangle?
Correct Answer: Chondrosarcoma
Description: Chondrosarcomas are slow-growing tumors, and their radiologic signs may be misleading and benign in nature. The lesions are generally round, ovoid, or lobulated. Their borders are generally well defined and at times corticated; at other times melding with adjacent normal bone occurs. Occasionally, peripheral periosteal new bone may be present perpendicular to the original cortex, giving the so-called sunray or hair-on-end appearance. Uncommonly, these lesions are ill defined and invasive. Aggressive lesions such as these have infiltrative, ill-defined, and noncorticated borders.
