Definition: In posterior encephalocele, the brain and meninges herniate through a defect in the calvaria.
Occipital encephalocele belongs to the family of neural tube defects, which occur in one among 2000 to 5000 live births.
Syndromic encephaloceles include Meckel-Gruber syndrome and various chromosomal abnormalities.
