摘要
目的评价卵巢囊腺癌的MRI诊断价值。材料与方法:对于17例经手术病理证实的卵巢囊腺癌(瘤)进行MRI回顾性分析。结果:卵巢囊腺癌(瘤)MRI表现与文献报道基本一致。浆液性卵巢瘤表现为典型的Ⅰ型,囊液信号均匀,浆液性囊腺癌呈Ⅱ型,其中Ⅱa型良恶性有部分重叠;当发现粘液性囊腺瘤存在时,应考虑交界性甚至浆液性、粘液性囊腺癌存在的可能性。结论:卵巢囊腺癌(瘤)最常见的部位为附件区。最常见的类型为Ⅰ、Ⅱ型。良性肿瘤以Ⅰ型常见,恶性肿瘤以Ⅱ型常见。MRI可以很好的显示卵巢肿瘤的内部特征,其中14例表现瘤体内部有分隔,呈多房状,可见索条状/飘带状分隔;对于缺乏浸润或转移证据的卵巢肿瘤的诊断和鉴别诊断有较高的价值。
Objective To evaluate MRI scan in the Diagnosis of ovarian cystadenocarcinina, Materials and Methods MRI findings in 17 patients with pathologically-proved ovarian eystadenocarcinoma （cystadenoma） were retrospectively analyzed. Results The MRI signs observed in this study were essentially in agreement with those reported in literatures. Serous cystadenoma took the typical type 1, the cystic fluid displayed homogeneous water attenuation. The serous cystadenocarcinoma was typically of type 2, Of type 2A, the malignant and benign tumors carried several same MRI features. When typical features of benign mucous cystadenoma were Present, the boundary, mucous, or even serous malignant tumor should be considered. Conclusion Ovarian neoplasms mainly locate at the adnexal area. Type 1 and type 2 are commonly seen. The benign turners often present as type 1, while the malignant ones often present as type 2. MRI can well display the interior features of the tumors, of which 14 cases display compart in the tumors, which is like multi-hole shape, rope or band shape compart can be seen, it plays an important role in the diagnosis and differentiation of ovarian tumors, especially for the tumors lack of the evidence of infiltration or metastases.
