MSCT和MR在输卵管积脓诊断中的价值

The value of CT and MRI in the Diagnosis of the Fallopian Tube Abscess

目的探讨输卵管积脓MSCT和MR的特征性表现，以提高对该病的诊断准确性。方法回顾性分析经手术和病理证实的39例输卵管积脓的MSCT和MR表现，其中22例行MSCT检查，17例行MRI检查。结果病灶位于右侧有18例，左侧有12例，同时累及双侧的有9例；39例(共48侧)主要表现为附件区囊性肿块，形态各异，病变呈多发囊状或串珠状改变的有30侧，呈腊肠状、葫芦状改变的有18侧；囊性区CT平扫呈等低混杂密度，MRT1WI呈低信号，T2WI呈高信号，DWI上呈高信号，ADC上呈低信号，增强扫描囊壁及分隔明显均匀强化，囊腔无强化。结论MSCT和MR检查能清楚显示输卵管积脓的数目、形态、边界、内部密度或信号特点及与邻近组织的关系，对输卵管积脓的诊断及鉴别诊断具有重要价值。

Objective:To explore the imaging features of computed tomography(CT)and magnetic resonance imaging(MRI)of fallopian tube abscess(FTA),so as to improve the diagnostic accuracy of the disease.Methods:CT and MRI manifestations of39FTA cases proved by surgery and pathology were analyzed retrospectively.22patients underwent CT,and the remaining17patients underwent MRI.Results:18cases were in the right,12cases in the left,9cases in both sides.39cases appeared as acystic mass in adnexa area,30cases appeared as multiple cystic form and beaded form,and18cases appeared as the sausage-shaped fold or gourd-shaped thickening.The cystic area showed mixed density on CT plain scan,low signal on T1WI,high signal on T2WI,high signal on DWI and low signal on ADC map.Cystic wall and interior separation showed obvious uniform enhancement.Conclusion:The CT and MRI could accurately demonstrate the number、shape、boundaries、internal density or signal characteristics of fallopian tube abscess,and the actual area and surroubding tissues,which is valuable in differential diagnosis of various causes.
