This video shows Anencephaly, Encephalocele and Polyhdromnios.
An encephalocele also known as cranium bifidum, is a neural tube defect characterized by sac-like protrusions of the brain and the membranes that cover it through openings in the skull. These defects are caused by failure of the neural tube to close completely during fetal development.
