目的探讨卵巢恶性生殖细胞肿瘤的CT特点。资料与方法回顾性分析62例卵巢恶性生殖细胞肿瘤的CT资料,包括卵黄囊瘤24例、未成熟畸胎瘤22例、无性细胞瘤11例和良性畸胎瘤恶变5例。结果囊性肿块9例,囊实性肿块19例,实性肿块34例。26例肿块内可见钙化。22例显示脂质成分。14例未成熟畸胎瘤可见盘曲带状略低密度影。2例良性畸胎瘤恶变囊肿内可见不规则头结节。11例可见腹膜种植结节。22例累及邻近脏器。10例盆腔淋巴结肿大。29例腹腔积液。结论卵巢恶性生殖细胞肿瘤的CT表现有一定特征性。结合临床,CT有助于本病的诊断和鉴别。
Objective To investigate CT features of malignant ovarian germ cell tumors. Materials and Methods Retrospective analysis of CT data of 62 cases of malignant ovarian germ cell tumors, including 24 cases of yolk sac tumor, 22 cases of immature teratoma, 11 cases of dysgerminoma and 5 cases of benign teratoma. Results Cystic mass in 9 cases, cystic solid mass in 19 cases, solid mass in 34 cases. 26 cases of mass calcification. Twenty-two patients showed lipid components. Fourteen cases of immature teratoma visible disc curved slightly lower density shadow. Two cases of benign teratoma malignant cyst showed irregular head nodules. 11 cases of visible peritoneal planting nodules. 22 cases involving the adjacent organs. 10 cases of pelvic lymph nodes. 29 cases of ascites. Conclusion The CT findings of ovarian malignant germ cell tumors have certain characteristics. Combined with clinical, CT help the diagnosis and identification of the disease.
