目的 卵巢交界性粘液性囊腺瘤 的MRI诊断及病理对照分析。方法 回顾性 分析我院35例经病理证实的卵巢交界性粘 液性囊腺瘤的临床资料及MRI检查资料,观 察的肿瘤部位、形态、大小，分房数目、 囊液信号、结节或乳头状突起、囊壁及分 隔厚度等情况，将其结果与病理对照分 析。结果 经病理对照，MRI发现了全部肿 瘤，共37个，对肿瘤检出率为100%；肿瘤 以完全囊性及囊性为主。35例患者中，左 侧16例，右侧17例，双侧2例；肿瘤呈类 椭圆形30个，分叶状7个。MRI对肿瘤大 小诊断结果与病理结果比较无统计学意 义(P>0.05)。结论 MRI可较好地诊断卵巢 交界性粘液性囊腺瘤，显示其肿瘤位置、 大小形态及病理特征，蜂窝状子房、T2WI 含低信号囊液、T1WI含高信号囊液、结节 或乳头状突起(≥5mm)及囊壁或分隔不规 则增厚(≥5mm)5个MRI征象对其鉴别诊断 有重要价值，可为临床治疗提供影像学依 据。

Objective MRI diagnosis and pathological analysis of borderline ovarian mucinous cystadenocarcinoma. Methods A retrospective analysis of clinical data and MRI image data was carried out in 35 patients with borderline ovarian mucinous cystadenocarcinoma confirmed by pathology in our hospital, tumor location, shape, size, the number of housing, cystic fluid signal, nodules or papillary projections, cystic wall and partition thickness were observed, results were cross-check analyzed with pathology. Results Pathological comparison showed that MRI found out all tumors (37 tumors), tumor detection rate were 100%, main tumors were complete cystic and cystic tumors. In 35 cases, 16 cases were on the left, 17 cases were on the right, 2 cases were bilateral; 30 tumors were oval tumors, 7 tumors were lobulated. There was no significant difference in tumor size diagnosis in MRI and pathological results (P>0.05). Conclusion MRI can diagnose borderline ovarian mucinous cystadenocarcinoma better, display that the tumor location, size and shape, pathological feature, cellular ovary, T2WI low signal cyst fluid, T1WI with high signal cyst fluid, nodules or papillary projections (≥5mm) and cystic wall or irregular thickened septum (≥5mm) 5 MRI siigns have important value in its differential diagnosis, can provide imaging bases for clinical treatment.
