摘　　要：目的:对比分析卵巢卵泡膜纤维瘤与Brenner瘤的影像表现与特征,探讨其诊断及鉴别诊断方法。方法:回顾性分析2015年1月-2021年12月经病理证实的22例卵巢卵泡膜纤维瘤和13例Brenner瘤的临床特征(年龄、肿瘤指标、是否伴发其他肿瘤)及影像特征(位置、大小、信号、钙化、ADC值、最大对比增强率、TIC类型、腹盆腔积液情况),采用两独立样本t检验和Fisher精确概率法进行统计学分析。结果:在临床特征方面,Brenner瘤较卵泡膜纤维瘤更容易伴发其他肿瘤,差异有统计学意义(P<0.05)。在影像特征方面,两者的病灶大小、ADC值、最大对比增强率、腹盆腔积液情况差异有统计学意义(P<0.05),余差异无统计学意义。结论:卵巢卵泡膜纤维瘤与Brenner瘤在影像表现上有很多相似之处,但又有各自特点。Brenner瘤较卵巢卵泡膜纤维瘤更容易伴发其他肿瘤,ADC值更低,强化更明显;卵巢卵泡膜纤维瘤较Brenner瘤体积大,更容易同时出现腹、盆腔积液。Objetive:To compare the imaging manifestations and characteristics of ovarian theca fibroma and brenner tumor,and to investigate the diagnostic and differential methods.Methods:The study included 22 cases of pathologically confirmed ovarian follicular membrane fibroma and 13 cases of Brenner tumor from January 2015 to December 2021.The clinical characteristics(age,tumor biomarker,accompanied tumor)and imaging characteristics(location,size,signal intensity,calcification,ADC value,maximum contrast enhancement rate,time intensity curve(TIC)type,abdominopelvic fluid)were retrospectively analyzed and compared using two independent samples t test and Fisher's exact probability method.Results:Clinically,brenner tumor was more likely to be associated with other tumors than follicular fibroma(P<0.05).As for the imaging features,the tumor size,ADC value,maximum contrast enhancement rate,and abdominopelvic fluid were significant different(P<0.05).Conclusion:Brenner tumor is more likely to be associated with other tumors,with lower ADC values,more pronounced enhancement,smaller size and less frequency of abdominopelvic fluid.
