摘　　要：目的探讨卵巢纤维瘤的CEUS表现及其应用价值。方法回顾性分析经手术病理确诊的46例卵巢纤维瘤患者的CEUS图像,观察其增强时间、增强水平、造影剂分布及增强水平随时相变化情况,分析CEUS对卵巢纤维瘤的诊断符合率。结果 46例中,2例CEUS中始终未见增强,余44例卵巢纤维瘤开始增强时间明显晚于子宫肌层[(15.87±2.79)s vs(12.01±2.75)s,t=2.87,P<0.05)]。在增强早期,35例(35/44,79.55%)呈低增强,9例(9/44,20.45%)为等或高增强;增强晚期44例(44/44,100%)均呈低增强。33例(33/44,75.00%)卵巢纤维瘤中造影剂分布均匀。CEUS诊断卵巢纤维瘤的符合率为89.13%(41/46)。结论卵巢纤维瘤具有较为典型的CEUS表现;实时CEUS技术可为卵巢纤维瘤的诊断和鉴别诊断提供有价值的信息。Objective To explore the enhancement features and clinical value of CEUS in diagnosis of ovarian fibromas. Methods Totally 46 patients with ovarian fibromas confirmed by pathology underwent CEUS, and the CEUS features, including arrival time, enhancement level, distribution of contrast media and the phase change of enhancement level were observed. The diagnostic accuracy of CEUS {or ovarian fibromas was analyzed. Results Among 46 cases, tumors in 2 cases （2/46, 4.35 %） did not enhance, while in 44 cases enhanced, and the arrival time of ovarian fibromas were obviously later than myometrium （[15.87±2.79]s vs [-12.01±2.75]s, t=2.87, P〈0.05）. In early phase, tumors in 35 cases （35/44, 79.55 % ） demonstrated hypo-enhancement, in 9 cases （9/44, 20.45 %） demonstrated iso-enhancement or hyper-enhance- ment. In the later phase, tumors in 44 cases （44/44, 100%） demonstrated hypo-enhancement. Tumors in 33 cases （33/ 44, 75.00%） showed diffuse homogeneous enhancement on CEUS. The diagnostic accuracy of CEUS for ovarian fibroma was 89.13% （41/46）. Conclusion Ovarian fibroma has characteristic CEUS features, which may provide information for differential diagnosis.
