摘　　要：目的探讨卵巢卵黄囊瘤的多层螺旋CT表现特点,旨在提高对该病的诊断准确率。方法回顾性分析经手术病理证实的9例卵巢卵黄囊瘤患者的临床及MSCT资料。患者发病年龄11～28岁,平均19.5岁。9例术前血清甲胎蛋白值为4255～187689μg/L,均明显升高。所有病例均行盆腔CT平扫及增强扫描,其中7例同时行上腹部CT平扫及增强扫描。结果全部患者均为单侧卵巢发病,右侧7例,左侧2例。肿瘤边界清楚,呈卵圆形或分叶状,均为囊实性肿物,且以囊性成分居多。肿物最大径为10.2～18.8 cm。增强后肿瘤的实性部分明显强化,瘤体内部肿瘤血管丰富。结论卵巢卵黄囊瘤的多层螺旋CT表现具有一定特征性,结合临床特点,可做出正确诊断。Objective To explore the MSCT features of ovarian yolk sac tumor and improve its diagnostic accuracy.Methods Clinical data and MSCT images of 9 patients with ovarian yolk sac tumor were reviewed retrospectively.The onset age ranged 11 to 28 years old,and the average age was 19.5 years old.Alpha Fetal Protein（AFP）was significantly higher before operation in 9 cases（4255~187689 ug/L）.All the cases were examined by both plain and enhanced pelvis CT scan,and 7 cases were also performed with abdomen CT scan.Results There were all unilateral ovarian masses.7 cases in the right side,and 2 in the left side.The CT plain scan demonstrated oval or lobulated mass with sharp margined.There was maximum diameter of mass with 10.2~18.8 cm.All the tumors were mixed solid and cystic,and predominantly cystic.The solid part of the mass was prominent enhanced.Abundant vessels were seen in tumors Conclusion There are some MSCT characteristics in ovarian yolk sac tumor,correct diagnosis can be made combined with the clinical features before operation.
