Symptoms can include an area on the back that looks abnormal. It can cause part of the spinal cord and areas around it to form outside of the body.
There are three main types.
Spina bifida imperfecta. Spina bifida occulta meningocele and myelomeningocele.

It is sometimes called hidden spina bifida. Spina bifida is a type of birth defect called a neural tube defect. Spina bifida is more common among whites and hispanics and females are affected more often than males.
Spina bifida occulta is the mildest type of spina bifida. The most common location is the lower back but in rare cases it may be in the middle back or neck. Many times spina bifida occulta is not discovered until late childhood or adulthood.
Although doctors and researchers don t know for sure why spina bifida occurs they have identified some risk factors. Spina bifida is a birth defect in which there is incomplete closing of the spine and the membranes around the spinal cord during early development in pregnancy. With it there is a small gap in the spine but no opening or sac on the back.
