摘　　要：目的观察输卵管原发高级别浆液性癌(HGSC)的MRI表现。方法回顾性分析经手术病理证实的24例输卵管原发HGSC,观察其MRI表现。结果24例HGSC中,MRI显示20例(20/24,83.33%)输卵管和/或卵巢肿块、12例腹膜增厚和腹膜饼状改变、9例腹膜结节、22例(22/24,91.67%)盆腔(n=12)或腹盆腔(n=10)积液及12例(12/24,50.00%)淋巴结肿大;4例仅见腹膜广泛增厚及腹膜结节(4/24,16.67%)而未见输卵管和/或卵巢肿块。MRI共检出23个肿块输卵管和/或卵巢肿块,包括单侧病变17例(5例右侧、12例左侧)、双侧病变3例,肿块最大径(7.11±3.68)cm,其中17个呈长条形或管形、4个形态不规则、2个呈圆形或椭圆形;12个为囊实性,8个为实性,3个呈囊性;囊性成分呈T1WI低信号、T2WI高信号,实性成分呈T1WI等或稍低信号、T2WI稍高信号,弥散加权成像(DWI)均表现为弥散受限;增强后肿块实性成分呈不均匀轻至中度强化,9个肿块边缘见连续、14个见不连续窄带样强化。结论输卵管原发HGSC的MRI表现具有一定特征性。Objective To observe MRI manifestations of primary high-grade serous carcinomas(HGSC)of fallopian tube.Methods Data of 24 patients with primary tubal HGSC confirmed by surgery pathology were retrospectively analyzed,and MRI manifestations of primary tubal HGSC were observed.Results Among 24 patients,MRI detected tubal and/or ovarian masses in 20 cases(20/24,83.33%),extensive peritoneal thickening in 12 cases and peritoneal nodules in 9 cases,retroperitoneal and pelvic lymph node enlargement in 12 cases,and pelvic(n=12)or peritoneal pelvic(n=10)effusion in 22 cases(22/24,91.67%).In 4 cases(4/24,16.67%),extensive peritoneal thickening and peritoneal nodules were detected,but no obvious tubal or ovarian masse was found.MRI totally detected 23 tubal and/or ovarian masses in 20 cases,involving single side in 17(right side in 5 and left side in 12)cases and both sides in 3 cases,with the maxiam diameter of(7.11±3.68)cm.Seventeen masses were long or tubular shaped,4 were irregular and 2 were round or oval,12 were cystic-solid,8 were solid and 3 were cystic.The cystic component of masses presented as low signals on T1WI and high signals on T2WI,the solid component presented as equal or slightly low signals on T1WI and slightly high signals on T2WI,with limited diffusion on diffusion weighted imaging(DWI)and uneven lightly to moderately enhancement.Continuous(n=9)or discontinuous(n=14)narrow band-like enhancement could be observed on the edges of all 23 masses.Conclusion MRI manifestations of primary fallopian tube HGSC had certain characteristics.
