Endodermal Sinus Tumor of the Ovary:Ultrasonography and CT Evaluation / 实用放射学杂志

ABSTRACT

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.
