摘　　要：目的探讨输卵管和腹膜结核的MRI表现特征。方法选21例经病理和实验室检查证实的输卵管和腹膜结核(TB)患者和27例卵巢癌(EOC)累及输卵管伴腹膜转移患者的临床和MRI及PET/CT表现进行比较分析,对病变形态、T1WI、T2WI和弥散加权成像(DWI)信号特点、表观弥散系数(ADC)值及强化特征进行分析研究。结果21例TB患者中,16例输卵管TB为单侧性(左侧9例,右侧7例),5例为双侧性。病变输卵管10例呈棒状,12例呈腊肠状S或L形,4例呈肿块状。病变输卵管于T1WI上呈略高信号,T2WI上呈软组织中等信号,DWI上呈高信号,ADC值测量范围为0.75-1.02×10-3mm2/s。结核性输卵管病变大小从0.7×2.2cm到1.5×4.5cm。TB性腹膜的厚度范围为1.6mm-3.2mm,呈薄层均匀平滑无结节增厚。结论输卵管呈管状、S/L形等非肿块样改变,在T1WI呈略高信号和腹膜呈薄层均匀性增厚并明显强化是输卵管和腹膜结核的特征表现。Objective To explore the MRI features of fallopian tube and peritoneal tuberculosis(TB).Methods Clinical data,MRI and PET/CT manifestations of 21 patients with fallopian tube and peritoneal tuberculosis confirmed by pathology and laboratory examination,and 27 patients of epithelial ovarian cancer(EOC)with peritoneal metastasis involving the fallopian tube were compared and analyzed.The morphology,T1WI,T2WI,and diffusion weighted imaging(DWI)signal characteristics,apparent diffusion coefficient(ADC)values,and enhancement features were analyzed and studied.Results Of 21 patients,16 were unilateral(9 on the left and 7 on the right),and 5 were bilateral.10 cases of fallopian tubes were rodshaped,4 were mass-like,and 12 were sausage-shaped or L-shaped.The lesion showed slightly high signal on T1WI,moderate signal on T2WI,and high signal on DWI.The ADC value measurement range is 0.75-1.02×10-3mm2/s.Size of fallopian tube lesions range from 0.7×2.2cm to 1.5×4.5cm.The thickness of the peritoneum ranges from 1.6 to 3.2mm,presenting as smooth uniform thickening.Conclusion Non mass-like changes such as tubular or S/L shaped fallopian tubes,thin uniform thickening of the peritoneum,and slightly high signal on T1WI are characteristic manifestations of fallopian tube and peritoneal TB.
