9例卵泡膜纤维瘤超声误诊探讨

Exploration of Ultrasound Misdiagnosis of 9 Cases of Follicular Membrane Fibroma

目的:探讨卵泡膜纤维瘤超声表现特征及误诊原因,提高超声诊断准确率。方法:收集福建中医药大学附属第二人民医院2014年1月1日—2022年10月30日经手术病理证实为卵泡膜纤维瘤患者的临床资料,选取其中9例超声误诊患者的临床及超声检查资料进行分析。结果:9例患者中,3例患者误诊为子宫浆膜下肌瘤(33.3%),6例误诊为卵巢癌(66.7%)。9例患者中有6例呈囊实性混合回声包块,实性占比80%~97%;4例后方出现回声稍增强;1例伴后方回声衰减;3例呈实性包块,实性包块中1例回声均匀,1例回声不均匀;8例0.40<血流阻力指数<0.5 (88.9%)。结论:卵泡膜纤维瘤声像图以实性及以实性为主的囊实包块为主,有一定特点,但缺乏特异性,易误诊,其发病部位、内部回声、边界等特征有助于超声诊断与鉴别。

Objective:To investigate the ultrasonographic features and causes of misdiagnosis of follicular membrane fibroma,and to improve the accuracy of ultrasonographic diagnosis.Methods:Clinical data of patients with surgical pathologically confirmed follicular membrane fibroma in the hospital from January 1,2014 to October 30,2022 were collected,and the clinical and ultrasonographic data of nine of these patients with ultrasound misdiagnosis were selected for analysis.Results:Of the 9 patients,3 patients were misdiagnosed with uterine subplasma leiomyoma(33.3%),and 6 with ovarian cancer(66.7%).6 out of 9 patients showed mixed cystic-solid echogenic masses,with solidity accounting for 80%~97%of the cases,4 cases showed slightly enhanced echoes posteriorly,and 1 case was accompanied by attenuated echoes posteriorly.3 cases showed solid masses,and among the solid masses,1 had homogeneous echogenicity and 1 had inhomogeneous echogenicity,and in 8 cases,0.40<resistance to blood flow index<0.5(88.9%).Conclusion:The sonogram of follicular membrane fibroma is dominated by solid and predominantly solid cystic masses with certain characteristics,but lacks specificity and is easy to misdiagnose.And its site of onset,internal echogenicity,borders and other features is conductive to ultrasound diagnosis and differentiation.
