Abstract:
Objective To investigate the charateristic CT features of pediatircs reproductive system of endodermal sinus tumor. Methods Thirteen cases with pediatircs reproductive system of endodermal sinus tumor confirmed by surgery and biopsy pathology all underwent CT and contrast-enhanced CT scans,and theire imaging features were then ananlyzed.Results On CT scan,7 cases of testicular or vagina endodermal sinus tumor of children appeared soft tissues mass with uneven density,small patchy hypodense shadows,and ill-defined boundaries.Contrast-enhanced CT scans reveal the solid masses were obvious uneven continuous enhance-ment,but small patchy hypodense shadows were not enhanced,local envelope were enhanced.CT scans reveal that 6 cases of ovaries endodermal sinus tumor showed the large cystic solid mass,predominantly cystic mass,including 2 cases of punctate and patchy cal-cification,and contrast-enhanced CT scans showed that solid part were enhanced obviously and with obvious strengthening vessels shadows.1 case of right ovaries endodermal sinus tumor with fat density shadow and small patchy calcification.Its pathological di-agnosis was the endodermal sinus tumors with mature cystic treatomas.Conclusion CT image has an advantage in the diagnosis of endodermal sinus tumor of the children's reproductive system,especially combined with serum AFP determination.
