摘　　要：目的:分析卵巢无性细胞瘤的超声声像图表现,探讨超声对该肿瘤的诊断价值。方法:回顾性分析2009年1月至2020年6月温州医科大学附属第一医院及温州医科大学附属第二医院经手术病理证实的21例卵巢无性细胞瘤的超声表现,总结其发病的部位、大小、形态、边界、内部回声及血流情况。结果:21例卵巢无性细胞瘤患者年龄13~64(20.8±8.6)岁;超声显示附件区实性为主、边界清晰肿块,均为单发,体积较大,16例呈分叶状;内部回声均不均匀,16例见“纤维血管间隔”及小叶结构,另外可见坏死囊性变的无回声区(10例);内部有较丰富的低阻血流,Alder血流分级Ⅲ级18例,Ⅱ级2例,Ⅰ级1例。结论:卵巢无性细胞瘤的超声表现有一定特征性,结合临床部分生化指标有助于提高该肿瘤诊断的准确性。Objective:To analyze the ultrasonographic features of ovarian dysgerminoma and to explore the value of ultrasonography in the diagnosis of ovarian dysgerminoma.Methods:The ultrasonographic features of 21 cases of ovarian dysgerminoma confirmed by operation and pathology in the First Affiliated Hospital of Wenzhou Medical University and the Second Affiliated Hospital of Wenzhou Medical University from January 2009 to June 2020 were retrospectively analyzed.The location,size,shape,boundary,internal echo and blood flow of the tumor were summarized.Results:The age of 21 patients with ovarian dysgerminoma was 13-64 years old,aged(20.8±8.6)in average.Ultrasonography showed that the adnexal area was mainly solid with clear boundary.All the masses were single and large,and 16 cases were lobulated.The internal echo was uneven,with“fibrous vascular septum”and lobular structure seen in 16 cases.In addition,there were necrotic cystic anechoic areas in 10 cases.There was abundant low resistance blood flow in the interior,with blood flow signal of gradeⅢin 18 cases,grade Ⅱ in 2 cases and grade Ⅰ in only 1 case.Conclusion:The ultrasonographic manifestations of ovarian dysgerminoma have shown certain characteristics,and the combination with some clinical biochemical indexes is helpful to improve the diagnostic accuracy of the tumor.
