42例卵巢源性盆腔巨大肿块CT分析

The CT Findings of Ovarian Giant Masses(42 Case Reports)

目的探讨女性卵巢源性盆腔巨大肿块的CT表现。方法回顾性分析42例经手术病理证实的卵巢源性盆腔巨大肿块的CT表现。CT征象包括肿块的形态、成分、增强特点及有无腹水、钙化等。结果 42例中,良性24例(粘液性囊腺瘤5例,浆液性囊腺瘤、混合性囊腺瘤及囊性畸胎瘤各4例,囊肿5例,卵泡膜细胞瘤及卵泡膜纤维瘤各1例);恶性18例(浆液性囊腺癌7例,内膜样癌3例,透明细胞癌及转移瘤各2例,颗粒细胞瘤、无性细胞瘤、不成熟畸胎瘤及低分化腺癌各1例)。良、恶性肿块的形态、最大径、成分密度、实质部分强化程度及与邻近组织器官的关系间的差异均具有统计学意义(P<0.05)。良性肿块大多数表现为均匀或含纤细分隔的椭圆形囊性肿块,而恶性肿块则多表现为含壁结节的囊性、囊实性或实性肿块。结论卵巢源性巨大肿块组织来源、生物学行为各异,其CT表现有一定特异性,CT对肿块定位及观察肿块内部成分及肿块周围结构改变等方面能发挥较大作用,为诊断和鉴别诊断提供重要信息。

Objective To investigate the CT features in giant masses of ovarian. Methods The CT findings in 42 cases of ovarian giant masses were retrospectively analyzed. The CT features were descripted as location,shape,components,enhanced features and ascites or calcification. ResultsOf all the 42 cases, 24 cases were benign and 18 cases were malignant. There were significant difference between benign and malignant masses in shape, maxin^um diameter,density,enhancement and relationship with surrounding organs. Benign masses often showed regular or oval cystic masses with uniiormit;, density or thin septa within.while malignant masses displayed as cystic with mural nodule,cystic and solid or solid. Conclusion Giant masses of ovarian have various origins and biological behaviour. CT can demonstrated the location, internal components and surrounding structures and provide important infonna- tions to the differential diagnosis.
