Exencephaly
Exencephaly is a type of Cephalic disorder. Exencephaly is a condition in which the brain is located outside of the skull. This condition is usually found in embryos as an early stage of anencephaly. As an exencephalic pregnancy progresses, the neural tissue gradually degenerates. It is unusual to find an infant carried to term with this condition because the defect is incompatible with survival.
