Objective To investigate the characteristics of different types of Small Ovarian benign tumors on TV-2D-CEU. Methods 63 cases of small benign ovarian tumors were analyzed with TV-2D-CEUS. Results Benign cystic ovarian tumor perfusion was in pericyst and septa or in papillae component, benign solid ovarian mass can be seen from the periphery to the central perfusion, pericyst thickness of corpus luteum cyst was significantly thicker than the oth-ers(P<0. 01). The difference had statistical significance (P<0. 05) in the parameters of curve between corpus luteum cyst and others. Conclusions TV-2D-CEUS can clearly show the enhancement Characteristics.%目的 探讨卵巢良性小肿块二维超声造影的特征.方法 经阴道二维超声造影,分析63例经手术病理及长期随访证实的卵巢良性小肿块的造影灌注特征.结果 卵巢良性囊性或囊实性小肿块特征为囊壁灌注清晰,囊内无或可见分隔及乳头灌注,内壁光滑或毛糙；卵巢良性实性小肿块的特征为由周边向中心的灌注.黄体血肿类囊壁厚度明显厚于其他类(P＜0.01),单纯性囊肿囊壁明显薄于其他类(P＜0.01).黄体血肿及炎性包块类的始增时间、达峰时间均明显早于畸胎瘤、巧克力囊肿、囊腺瘤、单纯性囊肿类(P＜0.05).畸胎瘤类的达峰时间明显晚于巧克力囊肿类(P＜0.05).结论 卵巢各类良性小肿块灌注模式有各自特征,经阴道二维超声造影对各类良性小肿块的鉴别诊断有意义.
