卵巢良性肿块的CT诊断

CT Diagnosis of the Ovarial Benign Tumor

目的:提高CT对卵巢良性肿块的诊断与鉴别诊断能力。材料与方法:搜集我院1999至2007年经手术和病理证实的卵巢良性肿块163例,共185个病灶。结果:卵巢囊肿45例,共60个病灶,卵巢内膜异位囊肿28例共32个病灶,浆液性囊腺瘤31例,黏液性囊腺瘤15例,囊性畸胎瘤35例共37个病灶,卵巢脓肿5例,卵巢纤维瘤2例共3个病灶,卵巢输卵管异位妊娠2例。结论:卵巢良性肿块多为圆形或卵圆形,边缘清晰,其内密度均匀,CT征象典型者定性诊断不难,巨大囊性肿块定位较难,良性肿块鉴别诊断可选择CT增强扫描,且结合B超及临床表现。

Purpose： Toexplore Cr imaging features of the ovarial benign tumor. Materials and Methods ： Cr imaging findings 163 eases ovarial benign tumors. Results： 45 eases with ovarian cyst, 28 eases with ovarian tuniea interna allotopia cyst, 31 eases with serous eystadenoma, 15 eases with mueinous eystadenoma, 35 eases with cystic teratoma, 5 eases with pyoovarium, 2 eases with fibroma of ovary, 2 eases with eeeyesis in ovaries or oviduct. Conclusion： The ovarial benign tumor are almost round or orbicular- ovate shape, dear borderline, aequalis density. Ct enhanced scanning, supersound and clinical symptom are useful to antidiastole.
