The Case of Sacrococcygeal Teratoma in an IVF Pregnancy: Is There any Association between Congenital Tumors and Assisted Reproduction Techniques?

Background: Sacrococcygeal teratoma (SCT) is a rare congenital tumor and its association with IVF pregnancy is not clear. There are limited reports of congenital tumors in IVF pregnancy. The exact embryogenesis of SCT is not known but a genetic etiology has been reported. Whether these congenital tumors have any association with assisted reproductive techniques remains obscure.

Case Presentation: In this study, a case of SCT in an IVF pregnancy with donor oocytes was reported. IVF was performed for bilateral tubal blockade and poor ovarian reserve. It was diagnosed antenatally by ultrasonography. Successful surgical treatment was performed in postnatal period and six months follow-up remained uneventful.

Conclusion: The purpose of reporting this case is to emphasize on the possibility of association of congenital tumors with assisted reproductive techniques and hence, the need for screening in these pregnancies. An association could not be detected based on few case reports and therefore, large population based studies are required to elucidate the effect of these reproductive techniques on occurrence of congenital tumors.
