【Abstract】 Objective To study CT diagnostic and differentiating diagnostic value of endometrial carcinoma in different stages.Methods The plain and contrast enhanced CT scanning were performed in 18 patients proved surgically and pathologically before the surgery. Of 18 patients, 11 cases were middle and high-differentiated adenocarcinomas, three low-differentiated adenocareinomas, two adeno-squamous carcinomas, one clear cell carcinoma and one endometrial metastasis. FIGO staging classification were two cases in stage Ⅰa, three Ⅰb, four Ⅱ,two Ⅲ and five Ⅳ. Results CT imaging characteristics including: (1) Uterine volume was enlarged differently; (2) Similar-fluid hypodensity without enhancement were filled in endometrial cavity in all patients; (3) Polypoid or papillary excrescences (four cases) and semi-global mass (three cases) protruding into uterine cavity were enhanced. Partial or broad thickening myometrium were enhanced homogeneously (eight cases>1/2 cycle, three cases<1/2 cycle);(4) Two cases in stage Ⅰ were misdiagnosed as stage I and one case in stage Ⅱ as stage Ⅰ. All of stage Ⅲ and stage Ⅳ cases were diagnosed correctly by CT.Conclusion The CT features of endometrial carcinomas are quite varied. Endometrial carcinoma can be diagnosed accurately combined with clinical dates. Vaginal plug (gauze) before CT scanning is helpful for assessment of cervical invasion.更多还原
