The Sonographic Diagnosis and Clinical Management of a Fetal Sacrococcygeal Teratoma: A Case Report

Abstract

A sacrococcygeal teratoma (SCT) is one of the most common fetal extragonadal germ cell neoplasms and carries high risk of maternal and perinatal complications. An example of a fetal SCT, associated with polyhydramnios, is presented in this case report. An antenatal surveillance sonogram revealed an increase in the size of the teratoma size and the amniotic fluid index. The patient underwent Cesarean delivery and postnatally, the infant’s teratoma was surgically excised. The pathologic examination of the specimen revealed a benign mature teratoma. This case demonstrated the important role that serial sonography had in monitoring this fetal pathology. Prenatal fetal sonographic assessment can play an important role for patients who need counseling and surgical planning.
