目的提高卵泡膜-纤维瘤组肿瘤 和浆膜下子宫肌瘤的CT鉴别诊断。方法 回顾性分析8例卵泡膜纤维瘤和16例浆膜 下子宫肌瘤的临床及CT表现。结果 卵泡 膜纤维瘤组：肿瘤大多与子宫分界清楚， 由卵巢动脉供血，增强肿瘤轻度延迟强 化，可有“纤细血管征”，可合并子宫内 膜增厚及腹水。浆膜下子宫肌瘤：肿瘤大 部分与子宫分界不清，由子宫动脉供血， 增强肿瘤强化较明显，可有“漩涡征”。 结论 通过观察肿瘤与子宫的关系、CT增 强表现、供血动脉及是否合并子宫内膜增 厚、腹水等，有助于卵泡膜-纤维瘤组肿 瘤和外突浆膜下子宫肌瘤作出诊断和鉴别 诊断。

Objective To improve the CT differential diagnosis of the group of ovarian thecoma-fibroma and suberous uterine leiomyoma. Methods The clinical and CT manifestation of 8 cases of ovarian thecoma-fibroma and 16 cases of suberous uterine leiomyoma were analyzed retrospectively. Results The group of ovarian thecomafibroma:most of the tumors and uterine state were clear, blood supply from the ovarian artery,tumors mild delayed enhancement,might have "slender blood vessels sign", could merger endometrial thickening and ascites. Suberous uterine leiomyoma: most of the tumors and uterine state were not clear, blood supply from the uterine artery, tumors enhanced obviously,might have "whirlpool sign". Conclusion By observing the relationship between tumor and uterine, CT enhancement performance, blood supply arteries and whether merger endometrial thickening,ascites, they were helpful to diagnosis and differential diagnosis of the group of ovarian thecoma-fibroma and suberous uterine leiomyoma.
