摘要
目的探讨卵巢性索间质肿瘤(OSCST)的超声表现,对照病理诊断结果分析其声像图特点,提高对该病的诊断水平。方法回顾性分析经手术病理证实的23例OSCST的超声表现,并与病理资料对照分析。结果 23例OSCST中实性肿块12例,囊实性肿块11例。12例实性肿块均为卵巢卵泡膜细胞纤维瘤,表现为形态规则、边界清、内部回声欠均匀的实性低回声,其中4例后方回声衰减。11例囊实性肿块中7例为卵巢颗粒细胞瘤、2例为支持-间质细胞瘤、2例为卵巢卵泡膜细胞瘤(OT),表现为囊实性低回声肿块,边界清,内可见大小不等的囊性回声区。本组OSCST术前超声诊断18例与病理诊断相符(18/23),误诊5例(5/23),其中3例误诊为浆膜下肌瘤、2例误诊为卵巢癌。结论 OSCST的二维超声表现有一定特征性,超声结合临床对其具有诊断价值。
Objective To study the correlation of ultrasonographic features of ovarian sex cord stromal tumors （OSCST） with pathology. Methods The ultrasound examinations of 23 patients with pathologically confirmed ovarian sex cord stromal tumors were reviewed. Results Of 23 OSCST, 12 ovarian theca cell tumors were solid masses with regular well-defined borders and heterogeneous low eehotexture. There was posterior echo attenuation in 4/12 tumors. The remaining 11 complex masses were ovarian granulosa cell tumors （7）, Sertoli-Leydig cell tumors （2）, and theca cell tumors （2） with well-defined borders, and low-level echoes in the solid components mixed with cystic areas of varying size.18/23 OSCST were correctly identified as ovarian tumors and 3/23 were misdiagnosed as subserosal fibroids, 2/23 as ovarian cancer. Conclusion Ultrasonographic appearance of OSCST combined with clinical features are useful for diagnosis.
