目的探讨卵巢卵泡膜细胞瘤-纤维瘤组肿瘤（OTFG）的二维及彩色多普勒超声表现及病理特点。方法回顾分析2010年1月-2014年12月内蒙古医科大学附属医院及内蒙古自治区人民医院收治的82例OTFG患者的超声表现，并与病理资料对照分析。结果82例患者OTFG均边界清晰，包膜完整，呈圆形或类圆形。检出实性肿块63例，其中41例（65．08％）为低回声，18例（28．57％）为等回声，4例（6．35％）为高回声。囊实性肿块19例（23．17％）。24例（29．27％）肿瘤内部未探及彩色多普勒血流信号，56例（68．29％）探及少许血流信号，2例（2．44％）探及较丰富血流信号。超声诊断误诊13例（15．85％）。超声表现为均匀低回声型误诊为子宫浆膜下肌瘤7例，阔韧带子宫肌瘤4例；超声表现为囊实性回声型误诊为卵巢癌2例（2．44％）。结论OTFG的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 evaluate the ultrasonographic appearances and pathologic femures of patients with ovarian theca-fibroma group （OTFG）. Methods From January 2010 to December 2014, uhrasonographic appearances and pathologic features of 82 patients with OTFG in the First Affiliated Hospital of Inner Mongolia Medical University and the People＇s Hospital of Inner Mongolia Autonomous Region were researched by retrospective analysis. Results 82 cases with OTFG were characterized by clear border, complete capsule and cycio- or quasi-circular. Moreover, there were 63 cases ovarian theca-fibroma tumors as solid masses, including 41 cases （65.08%） of hypoecho, 18 cases （28.57%） of iso-echoic and 4 cases （6.35%） of hyper-echoic, and 19 （23.17%） ovarian theca-fibroma tumors as complex masses. There were no obvious CDFI signal in 24 cases （29.27%） and less CDFI signal inside the masses in 56 cases （68.29%）, only 2 cases （2.44%） were full of plenty CDFI signal inside the mass. In addition, 13 cases （15.85%） were ul- trasonic misdiagnosis, including 7 cases were misdiagnosed as subserous myom of uterus and 4 cases of broad lgament hysteromyoma, while 2 cases （2.44%） were misdiagnosed as ovrian cancer. Conclusion The uhrasonographic appearances of ovarian theca-fibroma has a certain feature and a useful diagnostic value which combined with clinical data.
