Fetal Teratoma may arise from mid line structures from brain to coccyx or from gonads. Because Tarotama arise from Totipotenial cell ,the neoplasm's may contain elements of many tissues. Common site of origin for  Teratoma  is sacrum or coccyx. Sacrococcygeal Teratoma rare(35000 births) cysts, many contain solid areas with calcification. They may extend inferiorly between legs. They may infiltrate superiorly ,posterior to bladder. Obtruction of bladder & kidneys may occur if tumor has an Intrapelvic  component. Hydrops may develop due vascular shunt through the mass.
