摘　　要：目的：分析卵巢卵泡膜瘤-纤维瘤的多排 CT（MSCT）表现特征,提高其 CT 诊断水平。方法回顾性分析26例28个经手术病理证实的卵泡膜瘤-纤维瘤患者的临床及 CT 资料,分析 CT 影像学特征,并与病理对照。对病灶长径与有无腹水、有无绝经的关系进行分析。结果26例患者中,24例为单侧,2例为双侧,共28个病灶。28个病灶中卵泡膜瘤18个,卵泡膜纤维瘤6个,纤维瘤4个；肿瘤最长径为34.74～227.64 mm,均值为（101.06±42.25）mm,17例伴有腹水,有腹水组肿瘤长径大于无腹水组。所有肿瘤边界清楚,呈圆形或类圆形24个,分叶状4个；肿块呈实性22个,囊实性4个,囊性2个,20个密度不均匀；增强后无强化或轻度强化,强化程度0～5 HU 11个,5～10 HU 11个,10～20 HU 6个,4例增强后动脉期肿瘤内可见多条纤细血管影。结论卵泡膜瘤-纤维瘤 MSCT 常表现为单发类圆形实性肿块,边界清楚,增强后无强化或轻度强化,强化程度多〈20 HU,常伴少量腹水。这些特征对于病变的诊断和鉴别诊断有重要价值。Objective To analyze the imaging features of ovarian thecoma-fibroma in multi-slice CT （MSCT ）and improve the di-agnostic level.Methods CT features of 26 patients with 28 pathologically confirmed lesions were analyzed retrospectively.Correlation between tumor length and ascites and menopause was analyzed.Results Of 26 patients （28 lesions）,24 patients were unilateral, 2 patients were bilateral.Of 28 lesions,there were 18 ovarian thecoma,6 fibrothecoma and 4 fibroma.The longest diameter of tumor ranged from 34.74 mm to 227.64 mm （mean value 101.06 mm±42.25 mm）.The longest diameter of tumor in the group of ascites （n=1 7）was larger than that of without ascites.All the tumors had well-defined border,with 24 of them round or oval in shape,4 lobulated;with 22 of them solid in composition,4 mixed,2 cystic;with 20 of them inhomogeneous in density.The tumors showed no or mild enhancement,0-5 HU added CT value in 1 1,5-10 HU in 1 1,10 -20 HU in 6,with 4 cases showing multiple slim blood vessels during the arterial phase.Conclusion The typical imaging features of ovarian thecoma-fibroma were unilateral,oval,solid mass with well-defined border,no or mild enhancement （less than 20 HU）and accompanied by ascites.These characteristics will be helpful in the diagnosis and differential diagnosis of ovarian thecoma-fibroma.
