目的 分析子宫内膜异位囊肿破 裂(Endometriosis cyst rupture，ECR) 的MRI影像表现。方法 收集2012年1月至 2015年1月在我院接受诊治的ECR患者23 例，行MRI检查，分析T1WI及T2WI ECR的 影像学征象。结果 约60.87%(14/23)的 ECR在T1WI、T2WI呈高信号，且T2压脂序 列上信号未减低；约21.74%(5/23)病例 T1WI、T2WI呈略低信号，17.39%(4/23) T1WI、T2WI呈低信号，三者之间差异有统 计学意义(P＜0.05)。ECR患者中共有18例 盆腔积血，5例肠管或者子宫粘连，囊内 大多可见液液平面，占比65.22%。结论 利用MRI诊断ECR具有较好的应用价值，掌 握其影像征象有助于提高确诊率。

Objective To study the MRI manifestation of endometriosis cyst rupture. Methods Collected the MRI data of 23 patients with ECR treated in our hospital from January 2012 to January 2015, and analyzed the T1WI and T2WI manifestation. Results About 60.87%(14/23) of ECR shown high signal both on T1WI and T2WI, and on the T2 fat suppression sequences the signal did not reduce, and there were 21.74%(5/23) of ECR shown mild low signal on T1WI and T2WI, about 17.39%(4/23) shown low signal both on T1WI and T2WI, the differences were statistically significant (all P＜0.05). There were 18 cases complicated with pelvic hematocele, 5 cases complicated with intestinal and uterine adhesion, liquid-liquid plane could be seen in most of the cases(65.22%). Conclusion MRI had high application value in the diagnosis of ECR, and comprehensive grasp of the manifestation helps to improve the diagnosis rate.
