Dilated ventricles, Cleft lip, Spina Bifida, and Sacrococcygeal teratoma.

This video shows Dilated ventricles, Cleft lip, Spina Bifida, and Sacrococcygeal teratoma.
The sacrum is located in between the right and left iliac bones (hips) and forms the back of the pelvis. The sacrum, along with the coccyx and 2 sacroiliac joints make up the pelvic girdle. The top of the sacrum (S1) joins the last lumbar vertebra (L5) and together creates the lumbosacral spine.
Sacrococcygeal teratoma (SCT) is an unusual tumor, occurring in about 1 in 40,000 live births. The tumor is located at the base of the tailbone, called the coccyx. This birth defect is more common in girls than in males. Although the tumors can grow very large, they are usually not malignant (cancerous).
Sacrococcygeal teratomas are thought to arise from an area under the coccyx called “Henson's Node”. This is an area where primitive cells persist (germ cells) that can give rise to cells of the three major tissue layers of an embryo: ectoderm, endoderm, and mesoderm.
In fetuses, tumors may result from failure of developing tissues to undergo normal cytodifferentiation and maturation. Cervical teratomas may originate from the palate, nasopharynx, or thyrocervical area. They are usually closely related to but do not arise from, the thyroid gland.
Sacrococcygeal teratoma (SCT) is an unusual tumor that, in the newborn, is located at the base of the tailbone (coccyx). This birth defect is more common in females than in males babies. Although the tumors can grow very large, they are usually not malignant (that is, cancerous).
Sacrococcygeal teratoma (SCT) can be sporadic or familial and there appear to be different characteristics to these entities. It can be an isolated anomaly or occur as part of the Currarino triad when it is associated with anorectal malformations and sacral anomalies.
Sacrococcygeal teratoma (SCT) is a tumor that develops before birth and grows from a baby's coccyx - more commonly known as the tailbone. It is the most common tumor found in newborns, occurring in 1 out of every 35,000 to 40,000 live births.
Postnatal surgery for sacrococcygeal teratoma is a procedure conducted after birth to remove the tumor and tailbone to prevent the tumor from growing back. The tailbone is removed because the tumor grows from it, and if it's not removed, the tumor may grow back.
Unlike other neoplasias, sacrococcygeal teratomas are more common in twins than in singletons.
The most frequent type of fatal brain tumor is a teratoma. The use of ultrasound and magnetic resonance images allows the suspicion of brain tumors during pregnancy. However, the definitive diagnosis is only confirmed after birth by histology.
