【摘要】：目的卵巢子宫内膜样腺癌(OEC)是少见的卵巢恶性肿瘤,临床表现无特异性。本文分析OEC的MRI表现及病理基础,探讨MRI在诊断OEC中的价值。资料与方法回顾性分析经病理证实的8例OEC患者的临床资料,术前均行子宫及附件MRI平扫及增强扫描,分析其MRI及相关组织学表现。结果 8例中,单侧卵巢发病6例,其中左侧3例,右侧3例;2例为双侧卵巢发病,共10个肿块。肿块最大直径为3.5~16.5 cm,平均(10.5±4.1)cm。肿瘤边界部分模糊2例,清楚6例。MRI表现:囊实性肿块8个,2个为实性肿块,信号多混杂不均,实性部分多呈稍长或短T1、稍长T2信号,囊性部分呈长T1、长T2信号;增强扫描示8个肿块表现为实性部分斑片状明显强化,仅2个肿块表现为实性部分轻、中度强化,而囊性部分均表现为囊壁强化而腔内无明显强化。2例为原发性子宫内膜癌转移至卵巢,MRI表现为子宫内膜增厚,增强扫描呈轻度不均匀强化。结论 MRI能较好地反映OEC的病理特点,清晰地显示肿瘤的形态、成分及与周围脏器的关系等,对临床诊断OEC具有重要价值。
[Abstract]:Objective: ovarian endometrioid adenocarcinoma (OEC) is a rare malignant tumor of ovary. The MRI findings and pathological basis of OEC were analyzed, and the value of MRI in the diagnosis of OEC was discussed. Materials and methods the clinical data of 8 patients with OEC confirmed by pathology were retrospectively analyzed. MRI plain scan and enhanced scan of uterus and adnexa were performed before operation. The MRI and related histological findings were analyzed. Results of the 8 cases, 6 were unilateral ovarian disease, of which 3 were left and 2 were bilateral ovary, with a total of 10 masses. The maximum diameter of the tumor was 3.5 卤16.5 cm, with an average of 10.5 卤4.1 cm. The margin of tumor was blurred in 2 cases. MRI findings were as follows: cystic solid mass (8 cases), solid mass (2 cases), mixed signal intensity, long or short T 1 signal, long T 2 signal, long T 1 signal in cystic part and long T 2 signal intensity. Contrast-enhanced scan showed that 8 masses showed solid partial patchy enhancement and only 2 showed solid partial mild and moderate enhancement. The cystic part showed cystic wall enhancement, but no obvious enhancement in the lumen. 2 cases of primary endometrial carcinoma metastasis to ovarian carcinoma showed endometrial thickening on MRI, and the enhancement scan showed slight uneven enhancement. Conclusion MRI can reflect the pathological characteristics of OEC, and clearly show the shape, composition and relationship with surrounding organs of the tumor, which is of great value for clinical diagnosis of OEC.
