ABSTRACT
Objective To analyse CT appearances of fibroma and fibrosarcoma and to provide evidences for clinical diagnosis and treatment.Methods 8 cases with surgically-and pathologically-proved hard fibroma(nasal cavity,maxillary sinus and soft palate each and all 2 cases)and fibrosarcoma(nasal cavity and maxillary sinus each and all 1 case)were studied with retrospectively analysis.The scanning parameters were 5 mm thickness and interval for axial scanning.Results CT appearances of fibroma were single circular,semicircular or elliptical soft tissue masses which usually had homogeneous density,clear margin,thin and full envelope,wide base or a pedicel and slight or middle enhancement after contrast.The tumors grew distensibly,bones near the mass were constricted and thinned or absorbed but never destroried and the structures nearby were deviated but not involved.Fibrosarcoma showed such common CT manifestations as other malignant tumors in the same locations.Conclusion CT appearances of fibroma has some features,they are different from more common benign lesions.Fibrosarcoma can not be differeciated from other maglinant tumors,thier diagnosis must depend on pathology.
