摘　　要：目的探讨MR检查对于慢性肉芽肿型输卵管炎与原发性输卵管癌(PFTC)的诊断与鉴别诊断的价值。方法回顾分析19例经手术病理证实的输卵管肿块型病变的MRI征象,其中慢性肉芽肿型输卵管炎7例,PFTC 12例。所有病例均在GE1.5TMR上扫描,包括FES T1WI、FSE T2WI、LAVA及DWI(b=800)序列。结果 7例(双侧1例)慢性肉芽肿型输卵管炎MRI表现为附件区肿块8个,不规则形8例;囊实性7例,实性1例;患侧输卵管扩张6例;输卵管积液T1WI高信号(非出血)5例。DWI检查多呈高低混杂以高为主的信号,平均ADC值为(2.20±0.24)×10-3 mm2/s,增强后实性成份强化。12例(双侧2例)PFTC MRI表现为为附件区肿块14个,腊肠状8例,不规则形6例;囊实性5例,实性9例;患侧输卵管扩张12例;输卵管积液T1WI高信号(非出血)2例。DWI上多呈较均匀高信号,平均ADC值为(0.93±0.12)×10-3mm2/s,增强扫描实性成分主要呈轻-中度强化。结论 MR常规序列结合LAVA动态增强及对输卵管肿块性病变的鉴别诊断具有重要价值。Objective To explore the value of MRI in diagnosis of primary fallopian tube carcinoma and chronic granulomatous salpingitis. Methods The MRI of 7 chronic granulomatous salpingitis and 12 primary fallopian tube carcinoma confirmed by surgery and pathology was retrospectively analyzed. Results The 8 granulomatous lesions were unilateral masses in 6 patients and bilateral masses in 1 patient. The lesions were irregular（8）, solid （1） or cystic-solid （7）, hyperintense on T, WI （5） and diffusion-weighted imaging （8）. The mean apparent diffusion coefficient （ADC） value was 2.20±0.24×10^-3 mm^2/s. The solid components showed contrast enhancement. The 14 carcinomas were unilateral masses in 10 patients and bilateral masses in 2 patients. The tumors were sausage-shaped （8） or irregular （6）, solid （9） or cystic-solid （5）, hyperintense on TIWI （2） and diffusion-weighted imaging （14）. The mean ADC value was 0.93±0.12×10^-3 mm^2/s. The solid components showed mild to moderate contrast enhancement. Conclusion MRI features can aid the differential diagnosis of primary fallopian tube carcinoma and chronic granulomatous salpingitis.
