Huge soft tissue swelling is seen in the lower lumbar and pelvic regions. Sacrococygeal teratoma is the most common in the fetus and neonate. The aim from our cross sectional studies to assess the relation of the mass to the recum and urinary bladder and to exclude any associated dysraphic anomalies. Teratoma is a composite tumor has ectoderm, endoderm and mesoderm.
