| 目的 观察卵巢无性细胞瘤临床特征及超声表现。方法 回顾性收集35例经手术病理确诊的卵巢无性细胞瘤,分析其临床特征及超声表现。结果 35例平均年龄(23.3±9.4)岁。临床表现以盆腔包块(30/35,85.71%)、月经不调(9/35,25.71%)及腹痛(7/35,20.00%)为主;其中7例(7/35,20.00%)合并性腺发育不全;96.00%血清人绒毛膜促性腺激素(HCG)升高、83.33%糖类抗原125升高。超声主要表现为单发(单侧右侧多见)、体积较大 、分叶状(67.57%)、边界清晰(72.97%)实性肿块,内部可见小叶结构(64.86%)及条索样分隔(62.16%);CDFI显示肿块血流丰富(评分多为3),阻力指数较低(平均0.44±0.11)。结论 卵巢无性细胞瘤好发于年轻女性,多表现为单侧较大实性肿块;超声可见特征性纤维血管分隔及丰富低阻血流。 |

| Objective To observe clinical characteristics and ultrasonic manifestations of ovarian dysgerminoma. Methods Clinical and ultrasonic data of 35 patients with surgically and pathologically confirmed ovarian dysgerminoma were retrospectively analyzed. Results The mean age of 35 patients was (23.3±9.4) years. Predominant clinical manifestations of ovarian dysgerminoma included pelvic mass (30/35, 85.71%), menstrual irregularities (9/35, 25.71%) and abdominal pain (7/35, 20.00%), 7 cases (7/35, 20.00%) were found with gonadal dysgenesis. Elevated serum human chorionic gonadotropin (HCG) level and carbohydrate antigen 125 level were observed in 96.00% and 83.33% cases, respectively. The lesions mainly present as unilateral (right-sided), large (mean maximum diameter of cm), lobulated (67.57%) and well-defined (72.97%) solid mass, with internal lobular structures (64.86%) and cord-like septations (62.16%). CDFI revealed abundant blood flow (predominantly grade 3) with low resistance index (mean 0.44±0.11). Conclusion Ovarian dysgerminoma predominantly occurred in young women, typically presented as a large unilateral solid mass, with characteristic fibrovascular septa and abundant low-resistance blood flow showed on ultrasound. |
