Prenatal diagnosis and follow-up of giant sacrococcygeal teratoma: a case report

Objective: To emphasize the favorable effect of elective and planned delivery of newborns with giant sacrococcygeal teratomas on neonatal outcomes. Case: A 26-year-old, primigravid woman was admitted to hospital at 39 weeks of gestation because of severe polyhydramnios and a giant solid-cystic mass in the sacrococcygeal area of the fetus. A healthy newborn with a giant sacrococcygeal teratoma (25×25×20 cm) was delivered by cesarean section in elective conditions. On the second postnatal day, total excision of the mass was performed by pediatric surgeons. Histopathologic examination revealed mature cystic sacrococcygeal teratoma. The newborn was discharged with a well-developed scar tissue on 15th postnatal day. Conclusion: Sacrococcygeal teratomas diagnosed in the prenatal period can reach very large sizes. Especially those without heart failure can reach up to the term. The planning of elective delivery in these cases is of vital importance in terms of reducing perinatal mortality and morbidity.
