Antenatal diagnosis of sacrococcygeal teratoma--two different case reports.

Sacrococcygeal teratoma (SCT) is the most common fetal tumour. It may be readily diagnosed by two-dimensional ultrasonography in the early second trimester. Three-dimensional ultrasonography is recommended as a supplemental examination to obtain further detailed information for multidisciplinary management of SCT. In the following article we present two cases of sacrococcygeal teratomas which exhibited two different courses. In the first case, sacrococcygeal teratoma was diagnosed in the early second trimester. The condition of the fetus worsened during the follow-up and the parents opted for the termination of the pregnancy. The other one presented at a later gestational age. The baby was born alive, immediately operated upon and did well until the age of 1, when we checked her condition for the last time.
