Abstract

|
Sacrococcygeal teratoma is often diagnosed by ultrasound in the prenatal period. The fetus may develop high-output heart failure due to limited cardiac pumping ability and anemia secondary to sequestration of blood volume in the tumor. Eventually, fetal hydrops or placentomegaly may develop and these complications carry a grave prognosis. Therefore, careful monitoring by serial USG is needed, and any evidence of fetal hydrops should trigger prompt delivery or fetal intervention. Recently, fetal MRI may be helpful in assessing the exact tumor size, content, and intraabdominal extent to optimize prenatal and postnatal management. We experienced a case sacrococcygeal teratoma diagnosed by prenatal ultrasonography and fetal MRI at 28 weeks of gestation. At 31 weeks of gestation, preterm labor with sudden aggravation of polyhydramnios developed, we delivered the baby by Cesarean section due to concerns about fetal dystocia by the mass. Tumor was removed successfully 6 days after birth, and was diagnosed as immature teratoma. Thirteen months after delivery, the infant is healthy without any evidence of recurrence. So we present this case with a brief review of literatures
