【摘要】 目的 探讨卵巢子宫内膜异位囊肿MRI特点，评估MRI对卵巢子宫内膜异位囊肿的诊断价值。方法 收集2018年1月-2021年3月重庆大学附属三峡医院经手术病理证实的57例共79个附件区囊性病变进行研究，其中卵巢子宫内膜异位囊肿29个，非卵巢子宫内膜异位囊肿50个，分析病变的大小、形态、边缘、MR信号及周围情况，并评估各MRI征象对卵巢子宫内膜异位囊肿的诊断价值。结果 卵巢子宫内膜异位囊肿表现为：T1WI高信号28个、阴影征21个、T2黑点征10个、周围粘连21个、囊内液-液平面12个、增强囊壁强化26个，呈多发囊肿8例；卵巢子宫内膜异位囊肿和非卵巢子宫内膜异位囊肿T1WI高信号、阴影征、T2黑点征、周围粘连比较，差异有统计学意义（P<0.05）。结论 卵巢子宫内膜异位囊肿主要表现为T1WI高信号囊肿，阴影征及T2黑点征具有特征性，周围粘连为重要征象。MRI对卵巢子宫内膜异位囊肿诊断及鉴别诊断有重要价值。更多还原

【Abstract】 Objective To investigate the MRI characteristics of ovarian endometriotic cysts and evaluate the diagnostic value of MRI for ovarian endometriotic cysts.Methods From January 2018 to March 2021,57 patients with 79 accessory cystic lesions confirmed by surgery and pathology in the Chongqing University Three Gorges Hospital were studied, including 29 ovarian endometriosis cysts and 50 non-ovarian endometriosis cysts. The size, shape, edge, MR signal and surrounding conditions of the lesions were analyzed, and the diagnostic value of MRI signs for ovarian endometriosis cysts was evaluated.Results Ovarian endometriotic cysts manifested as: T1WI high signal(n=28), the shading sign(n=21), T2dark spot sign(n=10),and peripheral adhesions(n=21), fluid-liquid levels in the capsule(n=12), the cyst wall was strengthened(n=26), and 8 cases were multiple cysts.There were statistically significant differences in T1WI high signal, the shading sign, T2dark spot sign and peripheral adhesion between ovarian endometriosis cyst and non-ovarian endometriosis cyst(P<0.05).Conclusion Ovarian endometriotic cysts are mainly manifested as high signal cysts on T1WI. The shading sign and T2 dark spot sign are characteristic, and peripheral adhesions are important signs. MRI has important value in the diagnosis and differential diagnosis of ovarian endometriotic cysts.更多还原
