卵巢颗粒细胞瘤的超声表现及误诊分析

摘要

目的：探讨卵巢颗粒细胞瘤（ ovarian granulose cell tumor ， OGCT）的声像图特征及误诊原因，提高其诊断符合率。方法回顾性分析23例经手术病理证实为OGCT患者的临床及超声表现。结果23例OGCT，超声检出22例，检出率（22／23，96％），漏诊1例（1／23）；4例诊断正确（4／23，17％），6例仅提示肿块物理性质；误诊12例（12／23，52％），其中4例误诊为囊腺瘤，2例误诊为囊腺癌，3例误诊为卵泡膜细胞瘤，1例误诊为黄体血肿，1例误诊为巧克力囊肿，1例误诊为未成熟畸胎瘤。23例中实性5例，囊实性16例，囊性3例。彩色多普勒超声显示实性及实囊性OGCT血流信号丰富，阻力指数低。结论 OGCT超声表现多样，结合患者年龄、临床症状可提高本病术前诊断符合率。%Objective To analyse the ultrasonographic imaging and the cause of misdiagnosis of ovarian granulose cell tumor and to improve its diagnostic accurancy .Methods The clinical and urtrasonographic manifestations of 23 cases of ovarian granu-lose cell tumor proved by operation and pathology were retrospectively analyzed .Results 22 masses (22/23, 96%) were detec-ted with ultrasonography and 1 was missed;4 cases (4/23, 17%) were correctly diagnosed and 6 cases were suggested with tumor’s physical character merely;12 cases (12/23, 52%) were misdiagnosed, including 4 cases of cystadenoma, 2 cases of cystadenocarcinoma , 3 cases of thecoma , 1 case of corpus luteum hematoma , 1 case of chocolate cyst , and 1 case of immature ter-atoma.Of the 23 cases, 5 tumors manifesed as solid masses, 16 tumors as cysti-solid and 3 as cystic only.Rich blood flow signal and low resistance index were detected in solid , cystic-solid tumors.Conclusion The ultrasonographic manifestation of ovarian granulose cell tumor is various .Combined with patient ’ s age and clinical symptoms , the accurancy of diagnosis could be im-proved.
