摘　　要：目的探讨子宫内膜浆液性癌(USC)的MRI表现、临床及病理主要特点。方法回顾性分析经手术病理证实的USC患者23例,观察并分析其MRI、相关临床及病理资料。结果MRI表现为弥漫型12例,局限型11例,均表现为T1WI等信号,T2WI稍高信号,扩散加权成像(DWI)高信号,增强扫描以轻度强化为主,5例伴有宫外侵犯、转移;术后病理分期Ⅰ~Ⅱ期肿瘤12例,Ⅲ~Ⅳ期肿瘤11例,其中15例术前MRI分期与术后病理分期一致,8例存在低估情况。结论USC MRI可表现为宫腔内结节或肿物,增强后轻度强化,侵袭性强,易伴有淋巴结转移、腹膜转移。Objective To investigate the MRI manifestations,clinical and pathological characteristics of uterine serous carcinoma(USC).Methods Twenty-three patients with USC who had proved by surgery and pathology were analyzed retrospectively.The MRI,clinical and pathological data were observed and analyzed.Results Twelve patients were showed diffuse masses and 11 patients were showed local masses on MRI.All the patients had isointense signal on T1WI,slightly hyperintense signal on T2WI,hyperintense signal on diffusion weighted imaging(DWI)and mild enhancement.Five patients were extended into extrauterine companied with transformation.According to postoperative pathological staging,12 cases were stageⅠ-Ⅱ,11 cases were stageⅢ-Ⅳ.Preoperative MRI staging was consistent with postoperative pathological staging in 15 cases and underestimated in 8 cases.Conclusion The MRI features of USC are nodule or mass in uterine,with mild enhancement,with more aggressiveness,and with more probability of lymph node metastasis and peritoneal transfer.
