Abstract:
Objective To analyze the MRI features of endometrial stromal sarcoma(ESS)and to explore its value in clinical application. Methods Thirteen patients with histologically proven ESS were collected.All cases underwent non-contrast MRI scan and DWI,10 of which underwent contrast-enhanced MRI scan.The MRI features were discussed in combination with the pathological results after operation.Results In all lesions,6 lesions were located in endometrial cavity,4 in myometrium,1 in right wall of uterus and broad ligament,1 in cervical canals,and 1 in the top segment of vagina and pelvic.Plain MRI showed the lesions with hypointensity on T 1 WI and mixed hyperintensity on T 2 WI,which exhibited polypoid or multiple nodular masses.DWI showed the lesions with different hyperintensity.In 10 patients with post-enhanced scanning,moderate or marked heterogeneous enhancement of the masses were demonstrated,in which 6 presented plateau pattern of time-signal enhanced curve and 4 were persistent pattern.Conclusion ESS had some characteristic features on MRI,and DWI and dynamic contrast-enhanced examination can help to improve the diagnosis and differential diagnosis.
