目的探讨卵巢原发非上皮源性恶性肿瘤的CT表现。资料与方法回顾性分析经手术病理证实的18例20个卵巢非上皮源性恶性肿瘤的CT资料,结合文献探讨其CT表现特点。结果 18例20个卵巢非上皮源性恶性肿瘤中,颗粒细胞瘤10例11个,内胚窦瘤5例6个,未成熟畸胎瘤2例2个,无性细胞瘤1例1个。11个颗粒细胞瘤中以实性为主8个,囊性1个,囊实性2个。6个内胚窦瘤均呈囊实性,中心有大片囊变坏死区,增强后病灶内部及周边见数量不等血管样影。2例2个未成熟畸胎瘤呈囊实性,内见多发斑块状、斑点状钙化。无性细胞瘤1例呈囊实性分叶状肿块。结论卵巢原发非上皮源性恶性肿瘤的CT表现有一定的特点。
Objective To investigate the CT findings of ovarian primary non-epithelial malignant tumors. Materials and Methods Retrospective analysis of CT data of 18 cases of ovarian non-epithelial ovarian cancer confirmed by surgery and pathology was retrospectively analyzed. Results Among the 18 cases of 20 ovarian non-epithelial malignant tumors, there were 10 cases of granulosa cell tumor, 6 cases of endodermal sinus tumor in 5 cases, 2 cases of immature teratoma in 2 cases and 1 case of dysgerminoma in 1 case. Of the 11 granulosa tumors, 8 were solid, 1 were cystic, 2 were cystic and solid. 6 endodermal sinus tumors were cystic solid, cystic necrosis in the center of the area, enhanced within and around the lesion see the amount ranging from blood-like shadow. 2 cases of 2 immature teratoma cystic solid, see multiple plaque, spotted calcification. One case of dysgerminoma was cystic solid lobulated mass. Conclusion The CT findings of primary ovarian non-epithelial malignant tumors have certain characteristics.
