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。
Objective To investigate the characteristics of two-dimensional contrast-enhanced ultrasound in the diagnosis of small benign ovarian masses. Methods Transvaginal two-dimensional contrast-enhanced ultrasound was used to analyze the contrast-enhanced perfusion characteristics of benign and malignant ovarian masses in 63 cases confirmed by pathology and long-term follow-up. Results The benign cystic or cystic small lumps were characterized by clear wall perfusion, no or visible septum and papillary perfusion in the cysts, smooth or rough internal wall, and the benign and small ovarian masses were characterized by perinuclear perfusion. The thickness of luteal cyst wall was significantly thicker than other groups (P <0.01), and the cyst wall of simple cyst was significantly thinner than other groups (P <0.01). Luteal hematoma and inflammatory mass began to increase time and peak time were significantly earlier than teratoma, chocolate cyst, cystadenoma, simple cyst (P <0.05). The peak time of teratoma was significantly later than those of chocolate cyst (P <0.05). Conclusion All kinds of small benign ovarian tumor perfusion patterns have their own characteristics, transvaginal two-dimensional contrast-enhanced ultrasound in the diagnosis of various benign small lumps of significance.
