Anencephaly is the absence of a major portion of the brain, skull, and scalp that occurs during embryonic development. [1] It is a cephalic disorder that results from a neural tube defect that occurs when the rostral (head) end of the neural tube fails to close, usually between the 23rd and 26th day following conception.

An elevated MSAFP measured at 16–18 weeks gestation is a good predictor of open neural tube defects, however the test has a very high false positive rate, (2% of all women tested in Ontario, Canada between 1993 and 2000 tested positive without having an open neural tube defect, although 5% is the commonly quoted result worldwide) and only a ...
Spina bifida is a type of neural tube defect related to but distinct from other types such as anencephaly and encephalocele. [13] Most cases of spina bifida can be prevented if the mother gets enough folate before and during pregnancy. [3] Adding folic acid to flour has been found to be effective for most women. [14]

The condition is frequently, though not always, associated with anencephaly. The fetus is said to have acrania if it meets the following criteria: the fetus should have a perfectly normal facial bone, a normal cervical column but without the fetal skull and a volume of brain tissue equivalent to at least one-third of the normal brain size.

The skull does not close all the way in this deformity (especially at the occipital region). As a result, the amniotic fluid enters the brain, leading to eventual brain degeneration and anencephaly. [1] Craniorachischisis is on the extreme end of the dysraphism spectrum, wherein the entire length of the neural tube fails to close. [2]
