卵巢类固醇细胞瘤的超声表现

Ultrasound performance of ovarian steroid cell tumor

目的:探讨非特殊类型卵巢类固醇细胞瘤的声像图特征。方法:回顾性分析经病理证实为非特殊类型卵巢类固醇细胞瘤的21例患者临床资料及声像图。结果:非特殊类型卵巢类固醇细胞瘤声像图表现:21例患者均为单发,1例超声漏诊,20例均表现为卵圆形肿块,内部回声多不均匀,其中11例(11/20)为中等或中低混合回声,8例(8/20)为低回声,1例(1/20)为高回声; 20例内部均未见钙化;彩色多普勒示0级血供2例,Ⅰ级血供6例,Ⅱ级血供4例,Ⅲ级血供8例;合并盆腔积液13例(13/21)。结论:非特殊类型卵巢类固醇细胞瘤的声像图表现具有一定特征性,为以中低混合回声为主的实性肿物,但肿瘤直径<1 cm时超声易漏诊,肿块邻近子宫时超声易误诊为浆膜下肌瘤,应注意鉴别诊断,结合患者临床表现有助于提高非特殊类型卵巢类固醇细胞瘤的术前检出率。

Objective:To investigate the sonographic performance of ovarian steroid cell tumors.Methods:The clinical data and sonographic images of 21 patients with pathologically confirmed ovarian steroid cell tumors were retrospectively analyzed.Results:Ultrasound performance of ovarian steroid cell tumor:21 lesions in 21 patients,1 case missed,and the remaining 20 cases were all unilateral solid oval solid masses.The internal echoes were uneven and 11 cases(11/20)were moderate or moderately mixed echoes,8 cases(8/20)were hypoechoic,1 case(1/20)was hyperechoic.No calcifications were seen internally.Color Doppler showed 0-grade blood supply in 2 cases,and I-grade blood supply in 6 cases.There were 4 cases of gradeⅡblood supply,8 cases of gradeⅢblood supply,and 13 cases(13/21)of pelvic effusion.Conclusion:The sonographic features of SCT have certain characteristics,but the imaging of tumor with<1 cm is easy to be missed diagnosis.Ultrasound is often misdiagnosed as subserosal fibroid when located near the uterus.It is necessary to pay attention to differential diagnosis,combined with clinical manifestations of patients,to increase the preoperative detection rate of SCT.
