What causes occipital encephalocele?
Encephalocele happens when the neural tube does not close completely during pregnancy. The result is an opening anywhere along the center of the skull from the nose to the back of the neck, but most often at the back of the head (pictured), at the top of the head, or between the forehead and the nose.
Is encephalocele compatible with life?
Fetuses with an encephalocele are likely to die before birth. Approximately 21 percent, or 1 in 5, are born alive. Of those born alive, only 50 percent will survive.
Is encephalocele life threatening?
When the neural tube does not close, it can cause a sac-like bulge with brain tissue and spinal fluid that pokes through the skull. An encephalocele can be life-threatening.
How is encephalocele causes?
The exact cause of encephalocele is unknown. It a type of neural tube defect, meaning that the neural tube — a narrow channel that should close during early gestation to form the brain and spinal cord — does not close properly.
Can stress cause neural tube defects?
Abstract. Background: Studies suggest that maternal psychologic stress can increase the risk of congenital malformations, including neural tube defects (NTDs).
Is encephalocele a genetic disorder?
Encephaloceles are usually dramatic deformities diagnosed immediately after birth; but occasionally a small encephalocele in the nasal and forehead region can go undetected. There is a genetic component to the condition; it often occurs in families with a history of spina bifida and anencephaly in other family members.
What is occipital encephalocele?
Occipital Encephalocele. The congenital form is manifested by large but rare lesions that project through the occipital region, which constitutes the back and lower part of the cranium or skull. The lesions can vary from small pedunculated swellings to big lumps. These large growths can be even more than 20 cm in diameter.
What causes encephalocele?
Although the exact cause of encephalocele is unknown, scientists believe that many factors are involved. There is a genetic (inherited) component to the condition, meaning it often occurs in families that have family members with other defects of the neural tube: spina bifida and anencephaly.
What impact does encephalocele have on a baby’s health?
Impact the health outcomes of babies with encephalocele. The following is an example of what CDC researchers have found: Several factors appear to lead to lower survival rates for infants with encephalocele, including preterm (early) birth, low birthweight, having multiple birth defects, or being black or African American. 2,3
What are the rates of encephalocele?
Researchers estimate that about 1 in every 10,500 babies is born with encephalocele in the United States. 1 Although the exact cause of encephalocele is unknown, scientists believe that many factors are involved.
