巨大卵巢交界性黏液性囊腺瘤的CT特征

目的:探讨巨大卵巢交界性黏液性囊腺瘤的相对CT特征,以提高对巨大卵巢交界性黏液性囊腺瘤的认识。材料与方法:回顾性分析10例经病理证实为巨大卵巢交界性黏液性囊腺瘤的多层螺旋CT平扫及增强影像,并行多平面重组(MPR)、冠状面和矢状面最大密度投影(MIP)及容积再现(VR)图像重组。结果:10例巨大卵巢交界性黏液性囊腺瘤的多层螺旋CT影像均表现为与卵巢关系密切的巨大多房囊性病变,囊内可有稍不规则分隔及实性乳头状结节,增强后囊壁、分隔及实性结节强化。重建图像上有助于清晰显示肿瘤全貌。结论:巨大卵巢交界性黏液性囊腺瘤CT表现具有良恶交界性肿瘤的特征,仔细分析其CT特征有助于术前正确诊断。

CT Features of Massive Ovarian Borderline Mucinous Cystadenoma

Purpose:The relative CT features of massive ovarian borderline mucinous cystadenoma are to be explored,which improves the understanding of the tumor.Materials and Methods:The unenhanced and enhanced CT image findings were retrospectively analysed with the reconstruction technique including multiple planar reconstruction(MPR),coronal and sagittal planes of maximum intensity projection(MIP),and volume rendering(VR)in 10 cases with massive ovarian borderline mucinous cystadenoma confirmed pathologically.Results:The MSCT of all cases showed the features of giant multilocular cystic lesions which are closely linked to ovary.There was slightly irregularly spaced and solid papillary nodule in the capsule.After contrast scan,the capsule wall,septation and solid nodular tended to be enhanced.The reconstructed image helped to show tumor panorama clearly.Conclusion:The CT image findings of massive ovarian borderline mucinous cystadenoma show the characteristics of benign and malignant borderline tumor,so careful analysis of the CT features is helpful for correct preoperative diagnosis.
