摘　　要：目的：分析输卵管卵巢囊肿的 MRI 表现,提高诊断水平。方法回顾性分析15例经手术以及病理证实的输卵管卵巢囊肿的 MRI 表现,所有病例均行 MRI 平扫及增强扫描。结果9例为单发,其中5例位于右侧附件区,其余4例位于左侧附件区；6例为多发,位于两侧附件区。直径最大11.0 cm,最小3.8 cm,平均5.6 cm。所有病例均呈圆形或椭圆形,与输卵管相通,输卵管可见不同程度的扩张。13例囊内信号呈 T1 WI 低信号,T2 WI 高信号。2例病灶信号较复杂。增强扫描后,囊内容物未见强化,大多囊壁未见强化,伴感染囊肿壁可见强化。结论 MRI 能清晰显示输卵管卵巢囊肿的形态、信号及囊壁等影像学特征。Objective To evaluate MRI features of tubal ovarian cysts,to improve the understanding of its imaging characters. Methods 1 5 patients with tubal ovarian cysts proved by pathology and surgery were analyzed retrospectively.Results Among the 1 5 cases with cysts,9 cases were solitary lesions,including the right side of the attachment area in 5 cases and the left side of the attachment area in 4 cases.6 cases were multiple lesions located on both sides.The diameters of these cysts were from 3.8 cm to 1 1.0 cm,and average diameter was 5.6 cm.All cases showed that the cysts were round,communicated with fallopian tube.All tubals showed different degrees of expansion.The signals of the cysts showed hypointense on T1 WI and hyperintense on T2 WI.The signals in two cases were complex.After contrast medium administration,the walls of the cysts could be enhanced with different degrees.Conclusion MRI is useful in displaying the morphology,signal and the wall of the tubal ovarian cysts.
