【摘要】 目的 :探讨卵巢子宫内膜样癌(OEC)的CT、MRI表现及病理基础。方法:回顾性分析经手术病理证实的8例OEC的CT、MRI表现,并与手术和组织病理学结果进行对照分析。结果:8例OEC位于左侧5例,右侧3例。肿瘤最大径4.5~17.5 cm,平均9.2 cm。全部肿瘤均呈囊实性,6例形态不规则呈分叶状,2例呈圆形或卵圆形。肿瘤边界部分模糊7例,清楚1例。CT平扫:肿瘤实性成分CT值37~46 HU,平均41 HU,囊性成分CT值14~40 HU,平均25 HU;增强后肿瘤实性成分呈中等程度强化,动脉期CT值61~77 HU,平均66 HU,实质期CT值65~78 HU,平均71 HU。MR平扫:T1WI实性成分呈等信号,囊性成分呈低信号,T2WI实性成分呈稍高信号,囊性成分呈高信号,增强后肿瘤实性成分中等程度强化。8例OEC中合并子宫体内膜癌2例,其中1例经MRI检查,表现为子宫体部内膜不规则增厚,T1WI呈等信号,T2WI呈稍高信号,增强后呈中等程度强化,1例合并同侧卵巢巧克力囊肿。结论:CT、MRI能较好地反映OEC的病理特征,清晰显示肿瘤的形态、内部结构及邻近结构侵犯等情况,具有重要的定性价值,并为临床选择合理治疗方案提供依据。更多还原

【Abstract】 Objective: To study the CT and MRI imaging features and pathology of ovarian endometrioid carcinoma(OEC). Method: CT and MRI imaging features of 8 patients confirmed by surgery and pathology were analyzed retrospectively, and compare with the results of surgery and pathology. Results: Five tumors situated in the left and the 3 tumors others in the right ovary, the tumor diameter ranged from 4.5 to 17.5 cm, the average was 9.2 cm. All cases were cystic-solid lesions, irregular and lobulated contour were found in 6 cases, 2 cases were round or oval contour. Seven cases boundary was partial fuzzy, another one was clear. All the cases showed solid component’s CT value were 37~46 HU in CT plain scan, the average was 41 HU, cystic component’s CT value were 14~40 HU, the average was 25 HU. On enhanced CT, solid component was moderately enhancement with the CT value about 61~77 HU, the average was 66 HU in the arterial phase. Parenchyma stage value of CT was 65~78 HU, with an average of 71 HU.Underwent MRI, solid components were equisignal and cystic components showed low signal on T1WI. On T2WI imging, solid components showed slightly high signal and cystic component revealed high signal. Enhanced scanning showed moderately enhancement. In 8 cases of OEC complicated with uterine body membrane carcinoma in 2 cases, of which 1 case underwent MRI examination, manifested as irregular thickening of the uterine body membrane, showed T1WI signal, T2WI is slightly high signal intensity, enhancement after enhanced moderately, one case complicated chocolate cyst of ovary in the same side. Conclusion: CT and MRI can show the OEC pathology feature better. Also they can show the boundary of the tumor and block construction and the encroachment of circa-construction clearly, they possess the important qualitation value and provide reasonable treatment plan for clinic.更多还原
