<description><![CDATA[Objective: To discuss CT and MRI imaging features of aggressive fibromatosis (AF), especially the  characteristic signs of MRI, and to evaluate the value of diagnosis. Materials and Methods: The CT and MRI studies in 14 cases with pathologically proven AF were retrospectively analyzed. Results: Among 14 cases with AF, one cases could not be discovered by CT and all cases could be discovered by MRI. Appearances of lesion were infiltrating in 11 cases and mass-like in 3 cases. All cases were without calcification and lipo-tissue in the lesion and without edema on adjacent muscle structures. High density, equidensite or low density were seen on CT plain scans and high density on contrast enhanced scans. On MRI scans, equidensite or low signal intensity were demonstrated on T1WI, and high signal intensity on T2WI, as well as increased signal intensity after contrast enhancement. The  signal characteristics primarily reflected the underlying histologic composition of the lesions. Conclusions: MRI is more excellent than CT in delineating the site, shape, and extent of these lesions. MRI is valuable in detecting and differentiating AF.]]></description>
