OP-04 A study of fetal sacrococcygeal teratoma cases perinatal and postnatal evaluation

Objective

This study aimed to evaluate the perinatal and postnatal outcomes of fetuses diagnosed with sacrococcygeal teratoma during the antenatal period.

Methods

The records of patients who presented to our clinic between 2020-2023 and were diagnosed with fetal sacrococcygeal teratoma were retrospectively reviewed. Patient data including gestational age at diagnosis and delivery, teratoma size and type, presence of additional structural anomalies, genetic examination results, as well as the presence of polyhydramnios and hydrops, were collected. The sacrococcygeal tumors were classified into types 1 through 4. A multidisciplinary perinatology council team assessed the cases.

Results

The study included nine patients diagnosed with sacrococcygeal teratoma via ultrasound and confirmed postpartum. Of the sacrococcygeal teratomas, four were type 1, four were type 2, and one was type 3.Of the nine fetuses, six survived, while three died within the first week of life without surgery. Surgical intervention was performed during the first week of life for the surviving neonates. The teratoma types in the deceased patients were type 3 and type 2.

Conclusion

Although fetal sacrococcygeal teratoma cases are rare, successful results can be obtained with an early and accurate prenatal diagnosis, appropriate surgical intervention and frequent follow-up approach. The management of such cases is a complex process that requires a multidisciplinary approach. The size,content, growth rate and type of the tumor are the determining factors in terms of proper treatment and management planning.
