Abstract:
Objective To study the imagiological features of subtypes of osteosarcoma,and to improve the knowledge of these tumors.Methods X-ray findings of four subtypes of osteosarcoma in 8 cases proved clinically and pathologically were analysed retrospectively with review of literatare.Results 3 telangiectatic osteosarcomas localized in the upper end of femoral,the lower end of femoral and the lower end of humerus respectively,the fingings of X-ray were expansive and dissolved osseous destruction with soft tissue mass,aneurymal bone cyst-like in one case.3 parosteal osteosarcomas localized in the scapula,middler and lower end of femoral respectively,X-ray fingings appeared as condensans mass projected in soft tissue with radiolucent zone between cortiex of bone.One periosteal osteosarcoma localized in the lower end of femoral,CT showed osseous slight destruction with soft tissue mass.1 intrasseous well-differentiated osteosarcoma localized in the lower end of humerus,X-ray fingings included cystoid destruction,expansion in medullary cavity of bone and thin corter of bone.Conclusion Four subypes of osteosarcoma have ditinct roentgenographic features respectively,which is helpful for diagnosis.
