卵巢卵泡膜-纤维瘤组肿瘤的超声表现及病理对照分析

Comparative analysis of ultrasonographic features and pathology of the thecoma-fibroma group of ovarian tumors

目的探讨卵巢卵泡膜-纤维瘤组肿瘤的超声表现特点,与病理结果进行对照,以提高对卵巢卵泡膜-纤维瘤组肿瘤超声表现的认识。方法回顾分析经手术病理证实的53例卵泡膜-纤维瘤组肿瘤患者的临床和影像资料,对超声表现进行分型并与病理结果进行对比,对比结果进行χ2检验和Fisher确切概率法。结果卵巢卵泡膜-纤维瘤组肿瘤超声表现拟分为3种类型:低回声衰减型(Ⅰ型)22例,均匀低回声型(Ⅱ型)24例和囊实性回声型(Ⅲ型)7例。低回声衰减型和均匀低回声型超声诊断误诊率(5%,8%)与病理误诊率(0)比较,差异无统计学意义(P均>0.05);Ⅲ型超声误诊率(87%)与病理误诊率(0)比较差异有统计学意义(P<0.05)。结论超声对大多数低回声衰减型及均匀低回声型卵巢卵泡膜-纤维瘤可作出正确诊断。

Objective To investigate the ultrasonographic features of the thecoma-fibroma group of ovarian tumors and to compare them with pathological diagnosis in order to improve the understanding of this disease.Methods Ultrasonographic and clinical data of 53 patients with the pathologically proved thecoma-fibroma group of ovarian tumors were analyzed retrospectively.Ultrasonographic features were classified and compared with pathological diagnosis.Chi-square test was performed.Results All tumors were classified into three types by ultrasonography,posterior acoustic attenuation type（TypeⅠ,22cases）,homogeneous hypoechoic type（TypeⅡ,24cases）and cystic-solid mixed echoic type（Type Ⅲ,7cases）.Compared with pathological misdiagnosis ratio（0）,the misdiagnosis ratio of TypeⅠ and TypeⅡ were 5% and 8% respectively,and there were not statistical significance（χ^2=1.02,2.09,P 〈0.05）.The misdiagnosis ratio of Type Ⅲ was 87%,which was statistically significant compared with pathological misdiagnosis ratio（χ2=10.5,P 〈0.05）.Conclusion Most of the thecoma-fibroma group of ovarian tumors with posterior acoustic attenuation type and homogeneous hypoechoic type could be correctly diagnosed by ultrasonography.
