卵巢内胚窦瘤的B超和CT诊断

目的　探讨卵巢内胚窦瘤的B超和CT特征。方法　回顾分析 10例经手术和病理证实的卵巢内胚窦瘤的B超和CT资料 ,结合病理讨论其影像学特征。结果　 10例卵巢内胚窦瘤均作了B超检查 ,5例呈实质性回声像图 ,3例呈囊实性 ,2例呈囊性为主 ,实性部分血流丰富 ,局部可见蜂窝样改变。 10例中有 5例作了CT检查 ,边界大部分清楚光整 ,1例呈实质性肿块 ,内见较大不规则坏死区 ;2例呈囊实性 ,囊腔边缘不规则模糊 ;2例呈囊性为主 ,内见分隔。结论　卵巢内胚窦瘤的B超、CT表现有一定的特征性 ,尤其是CT ,结合年龄、血清AFP ,术前明确诊断是完全可能的

Endodermal Sinus Tumor of the Ovary:Ultrasonography and CT Evaluation

Objective To explore the imaging(Ultrasonography and CT)characteristics of endodermal sinus tumor of the ovary.Methods US and CT images of endodermal sinus tumor of the ovary in ten patients were analyzed proved by operation and pathology retrospectively and the imaging characteristics were discussed correlated with their pathology.Results All ten patients underwent sonography.In addition,five patients underwent CT scans.On sonography,five showed solid echo,two showed cystic-solid echo and the other two showed cystic echo.The blood flow of solid parts were abundant.In local part,honeycomebed appearance could be seen.On CT,one presented as solid mass with large irregular hyperdense necrotic area,two presented as cystic-solid mass with irregular and blurred cystic area,the other two presented as predominantly cystic mass with multiple internal septations.Conclusion Endodermal sinus tumor of the ovary has their characteristic sonography and CT features,particularly for CT.These imaging characteristics with the patients' age and serum a-fetoprotein levels can be helpful in presurgical accurate diagnosis.
