Abstract:
Objective To explore the imaging features of bone tumor of fibrous tissue origin.Methods 31 patients with bone tumor of fibrous tissue or igin confirmed by pathology were analyzed. All patients were examined by X-ray, of them, 6 by CT in the meantime.Results Non-ossifying fibroma(NOF n=14)occured commonly i n long bone,the imaging findings presented sacculated and expanded bone destruct ion which was encircled by sclerotic borders,bony septum could be observed iusid e the lesion.Ossifying fibroma(OF n=10)occured more in maxillofacial bone,there were circle or elliptical and expansive bone change,and most of them associated with local bone malformation.Depending on the ossified degree,the density of les ion,could be hyperdense,ground-glass opacity,cyst or mixed density,defined borde r,partly associated with sclerotic borders.Desmoplastic fibroma of bone(DF n=1) presented multiple patchy bony erosion at lateral of lower part of femur,and ext ending to articalar facies,ill-defined border,and soft tissue slightly swelling. Fibrosarcoma of bone(FS n=6) occured commonly in long bone,presened bitted-like or greater patchy osseous absorption with soft fissue mass,rarely periosteal rea ction and calcification.58.08% patients(18/31) were accurately diagnosed.The nat ure of 6 patients was undefined.Misdiagnosis was made in 7.Conclusion Most of NOF and OF are of specific imaging fin dings and can be accurately diagnosed before cperation.DF is of slight symptoms with invaded growth and is easily misdiagnosed.In the imaging features of FS are apparently different with various type and histological differentiation,it must be differentiated from other diseases.
