Analysis of Imaging Manifest of Desmoplastic Fibromas

Objective: To explore the imaging feature of desmoplastic fibromas.Method:To evaluate the pathological origination,clinical presentation and imaging presentation of desmoid tumor in four cases with review of the literature.Result: In the four cases,the lesions has different location.One is in abdominal wall,one is in chest wall and armpit,one is in the underneath of the femur and one is in abdomen.CT and MRI scan demonstrates the desmoid tumor originating from muscle with homogeneous formation.The lesion manifests lower attenuation lump contrasted to the adjacent soft tissue in CT scan and the different components of which lead to various signal in T2WI.After intraveinous contrast material administration,the lesion which has no clear margin always demonstrates inhomogeneous,slight enhancement.Conclusion: Desmoid tumor is an aggressive benign tumor.Because imaging findings have no characteristic,its diagnosis depends on pathological examination.
