中文摘要：
目的 对卵巢腺纤维瘤（OAF）的临床、CT及MRI表现分析,提高诊断水平。方法 对92例OAF临床、CT及MRI资料回顾性分析,总结其特点。结果 OAF单侧发生概率占91.3%,浆液性占89.1%、良性占97.8%,伴有子宫或/和卵巢病变占40.2%。OAF临床表现不典型,按有无伴随子宫或（和）卵巢病变分为2组,对临床表现及实验室指标对比分析,发现仅月经异常发生率的差异有统计学意义,而其他指标的差异无统计学意义。CT平扫、CT及MRI增强表现无特征性,而MRI T2WI“黑色海绵征”和DWI高信号出现概率分别为40.0%、65.0%。结论 MRI T2WI“黑色海绵征”和DWI高信号可能有助OAF诊断。
英文摘要：
Objective To explore the clinical, CT and MRI features of ovarian adenofibroma （OAF） and improve the diagnostic level. Methods Ninety-two cases of OAFs were analyzed retrospectively and summarized the features including clinical manifestations, CT and MRI images. Results The probability of unilateral, serous and benign OAFs were 91.3%, 89.1% and 97.8%. OAFs associated with uterine or/and ovarian lesions was 40.2%. The clinical manifestations of OAF was not typical. These OAFs were divided into 2 groups according to whether or not accompanied with uterus or/and ovarian lesions. The clinical manifestations and laboratory indexes were only found abnormal menstruation rate （P 〈 0.05 ）, but there were no significant difference between other indexes. The performance of CT plain scan and CT/MRI enhanced scan had not characteristic.The percentage of the ＂black sponge＂ on T2WI image and hyperintensity on DWI image of OAFs were 40.0% and 65.0%. Conclusion The ＂black sponge＂ on T2WI image and hyperintensity on DWI image may be helpful to diagnose OAF.
