卵巢非上皮性肿瘤的影像诊断与病理对照研究

目的 分析卵巢非上皮性肿瘤的影像表现与病理结果,提高对卵巢非上皮性肿瘤的影像诊断与鉴别诊断.方法 收集经手术病理证实的卵巢非上皮肿瘤患者34例,分析其影像特征,并与病理对照.结果 畸胎瘤13例,卵巢颗粒细胞瘤6例,卵巢纤维瘤6例,卵泡膜细胞瘤5例,无性细胞瘤2例,卵巢内胚窦瘤2例;各种卵巢非上皮性肿瘤各有其影像及临床特征.结论 卵巢非上皮性肿瘤CT及MR表现有一定的特征性,结合发病年龄、临床症状及生化检查,可作出定性诊断.

Comparative study on image diagnosis and pathological results of non-epithelial ovarian tumors

Objective To improve the imaging diagnosis and differential diagnosis of non-epithelial ovarian tumor.Methods 34 patients with non-epithelial ovarian tumor confirmed by pathology were analyzed retrospectively.The image features of each patients were analyzed and compared with surgical pathology.Results The results exhibited 13 cases of teratoma,6 cases of ovarian granulosa cell tumor, 6 cases of ovarian fibroma, 5 cases of thecoma, 2 cases of dysgerminoma,and 2 cases of endodermal sinus tumor.All kinds of non-epithelial ovarian tumors had its imaging manifestations and clinical features.Conclusion Non-epithelial ovarian tumors have certain characteristic CT and MR performance,and combining the onset age,clinical symptoms and biochemical examination,can make the qualitative diagnosis.
