Two neonatal cases of giant sacrococcygeal teratoma(SCT)were experienced. Case 1: 2780g 31w5d baby boy. Diagnosed at 29w by the routine ultrasonography(US). Bone by caesarian section because of fetal distress. The tumor had already ruptured. After the resuscitation, the resection of the tumor was done. But he died because of DIC. Case 2: 2680g 33w4d baby girl. Diagnosed at 32w by the routine US and magnetic resonance imaging(MRI). She was born by the caesarian section, and underwent the emergency surgery. She was discharged safely.<BR>Neonatal SCT is not so rare in the teratomas and its incidence is 1/4000-40000 birth. The differential diagnosis to the meningocele is important, but it is relatively easy by the prenatal US and MRI. The complications of the neonatal giant SCT are intrauterine growth retardation, urinary tract obstruction, high-output cardiac failure, rupture, DIC(with/without rupture), etc. So it is nessesary for the cases with such a giant SCT to be diagnosed by noninvasive imaging, to be managed intensively, to be born by the caesarian section preparing for the emergency surgery.
