Comparison of CT and MRI in diagnosis of abdominal invasive fibromatosis

Objective To compare the diagnosis of CT and MRI in abdominal invasive fibromatosis.Methods The clinical data of 24 patients who were diagnosed as invasive fibroma of the abdomen by postoperative pathological examination in our hospital from June 2017 to June 2019 were retrospectively analyzed.All patients underwent CT and MRI.Compared the diagnostic effect and imaging features of CT and MRI in abdominal invasive fibromatosis.Results The pathological examination of postoperative excisions showed that of the 24 patients,18 lesions were located in the abdominal wall(2 in each of the upper left and upper right abdominal walls,6 in the lower left abdominal wall,7 in the lower right abdominal wall,and 1 in the umbilical cord),and 4 lesions were located in the abdominal cavity,2 cases were located behind the peritoneum.Among the 24 patients,there were 17 cases(70.83%)with a fibroma diameter>5 cm,22 cases(91.67%)with a single event,and 14 cases(58.33%)with irregular morphology.18 cases(75.00%)were detected by CT scan,13 cases showed slightly lower density,5 cases showed equal density,no necrosis,fat and calcification were found in the scan;in the enhanced scan,there were 12 cases of strips and patchy non-enhanced low-density shadows in and around the lesion.Patchy low-density low-enhancement images.In the arterial phase,most of the lesions were unevenly enhanced(mild),the venous phase continued to strengthen,and the delayed phase was significantly strengthened.23 cases(95.83%)were detected by MRI,of which 14 cases showed equal signal on T1WI,9 cases showed slightly lower signal,T2WI showed slightly higher signal,T2WI showed significantly higher signal in SE sequence;dynamic enhancement showed that the lesion was in the arterial phase The venous phase showed uneven enhancement(moderate),and the delayed phase was significantly enhanced.Among them,16 cases showed low-signal shadows.The detection rate of MRI was higher than CT(P<0.05).Conclusion Both CT and MRI have characteristic imaging findings on invasive fibromatosis of the abdomen,but MRI has higher detection rate of this disease,which is worthy of promotion.
