Sacrococcygeal teratoma: prenatal diagnosis and management.
Although sacrococcygeal teratoma is a rare and potentially malignant tumor, 10 cases were documented during a 5-year period at the University of Toronto Perinatal Complex. Diagnosis was made in the six cases in which prenatal ultrasound examination was performed. One patient with twins elected to terminate the pregnancy at 19 weeks. In three of the cases diagnosed prenatally, serial ultrasound was performed. There was a 75% cesarean section rate. In all cases diagnosed prenatally, the large tumor size affected the mode of delivery. In the four cases without prenatal diagnosis, two infants were delivered vaginally, and two were delivered abdominally for obstetric reasons. There was one case of neonatal morbidity where tumor vascularity and rupture resulted in hypovolemic shock. All tumors were resected and found to be benign. A plan of management is recommended and, with appropriate obstetric and pediatric care, a good outcome can be anticipated in most cases.
