摘要
目的:探讨儿童卵巢肿瘤的MRI特征。材料和方法:搜集1995～2002年10例经超声和手术病理证实的卵巢肿瘤的临床MRI资料,分析MRI所见,评价MRI对诊断卵巢病变的意义。结果:卵巢良性肿瘤5例,其中卵巢囊性畸胎瘤3例,卵巢黏液性囊腺瘤2例。卵巢恶性肿瘤5例,其中卵巢卵黄囊瘤2例,卵巢恶性畸胎瘤2例,卵巢颗粒细胞瘤1例。结论:MRI是目前诊断卵巢病变较好的影像学方法,特别是其多方位多序列成像方法对卵巢良恶性肿瘤的组织学特征的显示,能为临床诊断和治疗提供可靠的依据。
Objective: To study MRI manifestations of ovarian tumors in children. Methods: Clinical and MRI data of 10 pediatric cases with surgically-proved ovarian tumor during 1995～2002 period MRI fingdings were analysed. The value of MRI in its diagnosis was assessed. Results: Five cases had benign tumors of ovary including cystic teratoma(3 cases), mucinous cystadenoma(2 cases). Five cases had malignant tumor of ovary, including yolk sac tumor(2 cases), malignant teratoma(2 cases), granuloma cell tumor(1 case). Conclusion: MRI is an effective modality in diagnosing ovarian tumor in children, especially in showing the characteristic tissue of the tumor with mutiple-planar and multi-serial method. It is helpful in diagnosing and treatment planning.
