【摘要】 目的 探讨原发性输卵管癌（PFTC）的CT和MR表现。方法 回顾性分析9例手术与病理证实的PFTC的CT和MRI表现,7例行CT检查,2例行MR检查。结果 9例PFTC均表现附件区肿块,8例为单侧,1例为双侧。表现为输卵管内实性肿块2例,管状囊性肿块伴管壁软组织结节3例,不规则囊实性肿块2例,腊肠形实性肿块2例。7例伴有输卵管积水。实性肿块及管壁结节呈均匀或不均匀软组织密度,结节在MR上T₁WI呈低信号,T₂WI呈稍高信号,输卵管积水呈明显长T₂高信号。增强扫描实性肿块、管壁结节及囊实性肿块的实性部分呈轻度至中度强化。腹膜及盆腔转移4例,网膜转移3例,肝转移3例,腹水4例。结论 PFTC通常表现为附件区腊肠样或管形囊性或实性肿块,囊性肿块伴有管壁结节,输卵管积水是重要的间接征象,不典型PFTC与卵巢癌影像表现相似,需结合临床症状综合诊断。更多还原

【Abstract】 Objective To explore CT and MR imaging characteristics of primary fallopian tube carcinoma（PFTC）.Methods The imaging data of CT and MRI of 9 patients with pathologically proved PFTC were retrospectively analyzed.7 patients were examined by CT and 2 patients were examined by MR imging.Results Eight patients with PPFTC had unilateral adnexal masses and 1 patient had bilateral masses.The lesions appeared as solid masses at the fallopian tube in 2 cases,tubular-shaped cystic masses with mucosal papillary nodes in 3 cases,irregular cystic and solid masses in 2 cases and solid masses like sausage in 2 cases.Seven cases were in company with hydrosalpinx.The nodes and solid masses usually presentd homogeneous or heterogeneous soft-tissue attenuation on CT,and were hypointense on T₁WI and hyperintense on T₂WI.After injection of contrast medium,nodes and solid masses enhanced slightly to middlingly.The sites of metastasis included the peritoneum and pelvic（n=4）,omentum（n=3）,liver（n=3） and 4 patients with ascites.Conclusion PFTCs usually manifest sausage-liked or tubal-shaped cystic adnexal masses or cystic and solid masses,cystic masses often with mucosal papillary nodes,hydrosalpinx is significantly indirect signs.Nontypical PFTCs commonly presente adnexal masses on CT and MR imaging which mimics ovarian carcinoma,the diagnosis should combine with clinical manifestation.更多还原
