CT检查在卵巢交界性浆液性肿瘤与黏液性肿瘤鉴别中的效果

Effect of CT examination in the differentiation between serous and mucinous tumors in ovarian borderline tumors

目的探讨分析CT检查在卵巢交界性肿瘤(BOT)浆液性肿瘤与黏液性肿瘤鉴别中的应用效果。方法选取2018年7月~2019年7月鞍山市中心医院收治的37例卵巢浆液性交界性肿瘤患者、40例卵巢黏液性交界性肿瘤患者作为研究对象,分别作为浆液性BOT组、黏液性BOT组。两组患者均采用CT检查。比较两组患者的CT形态学特征及影像学特征。结果黏液性BOT组的囊腔分房数目高于浆液性BOT组,囊腔直径≥10 cm的比例大于浆液性BOT组,差异有统计学意义(P<0.05)。黏液性BOT组的肿瘤边界清楚比例高于浆液性BOT组,但黏液性BOT组的囊液密度均质占比率低于浆液性BOT组,黏液性BOT组中实性成分占比也低于浆液性BOT组,差异有统计学意义(P<0.05)。在软组织形态中,黏液性BOT组的软组织形态以囊壁、间隔增厚为主,而浆液性BOT组中软组织则主要呈地图样分布,差异有统计学意义(P<0.05)。结论卵巢浆液性交界性肿瘤、黏液性交界性肿瘤在CT检查时其影像学特征存在较大差异,CT检查能为两者的鉴别提供重要的参考依据。

Objective To investigate and analyze the effect of CT examination in the differentiation of serous and mucinous tumors in ovarian borderline tumor(BOT).Methods From July 2018 to July 2019,37 patients with ovarian serous borderline tumor and 40 patients with ovarian mucinous borderline tumor treated in Anshan Central Hospital,were selected as study subjects.They were selected as the serous BOT group and the mucinous BOT group,respectively.CT examination was performed in both groups.CT morphological and imaging features were compared between the two groups.Results The number of sac compartmentalization in the mucinous BOT group was higher than that in the serous BOT group,the proportion of sac diameter≥10 cm in the mucinous BOT group was larger than that in the serous BOT group,the differences were statistically significant(P<0.05).The clear tumor boundary rate in the mucinous BOT group was higher than that in the serous BOT group,nevertheless,the homogeneous ratio of bag fluid density in the mucinous BOT group was lower than that in the serous BOT group,and the proportion of solid components in the mucinous BOT group was also lower than that in the serous BOT group,the differences were statistically significant(P<0.05).In soft tissue form,the soft tissue morphology in the mucinous BOT group was mainly cystic wall and septal thickening,while the soft tissue in the serous BOT group was mainly distributed in map shape,and the difference was statistically significant(P<0.05).Conclusion The imaging features of serous and mucinous tumors in ovarian borderline tumors differ greatly during CT examination,CT examination can provide important reference for their differentiation.
