Abstract：Objective: To explore CT and MRI features of aggressive fibromatosis. Methods: The CT and MRI findings of aggressive fibromatosis confirmed by surgical pathology in 23 cases were retrospectively analyzed. Results: CT examination: the abdominal wall outside type of 7 cases: 4 mass clear boundaries and 3 unclear; 5 mass with homogeneous density and 2 uneven; 3 even density, 2 equal low density, 2 low density. The abdominal wall type of 16 cases: 15 mass clear boundaries and 1 unclear; 13 mass with homogeneous density and 3 uneven; 9 even density, 4 slight low density, 3 equal low density. The enhancement of 12 cases: 4 moderate enhancement and 8 slight enhancement in the arterial phase, mild persistent enhancement in the venous phase and delayed phase. MRI examination: 1 mass signals even and 3 uneven; 2 slightly high signal and 1 high with low signal and 1 high with low or on T2WI; 1 low or even signal and 3 low signal on T1WI; 2 low signal and 2 high signal on T2WI fat suppression. 4 bone invasion damaged, 1 compression, 1 uterine, sigmoid compression. Conclusion: The CT and MRI manifestations of aggressive fibromatosis have certain characteristics features, CT and MRI examination is of great value in the diagnosis of the disease.
