Congenital encephalocele is a neural tube closure defect that presents herniation of cranial contents because of a cranial congenital malformation, the occipital encephalocele is the most common form of this defect.() Encephalocele often occur because of occurrence of occipital bone defect within the fourth week of embryogenesis and it can be extended for foramen magnum and affect the posterior arch of the atlas.() Hernia sac content varies and worst prognosis is large brain content inside the sac.(,) Etiology of this malformation include genetic and environmental factors, such as folate deficiency that is prevented with the use of folic acid supplements during preconception period until 12 weeks of gestation, and also for poor prenatal care.(,) Although this malformation varies in several demographic regions, neural tube closure defects incidence is approximately 1 in 1,000 live births.(,)

Both adequate prenatal care and imaging tests are importance to identify variations of this affection. For this reason, clinical case reports and their on encephalocele images are important.
