"Acrania anencephaly sequence or acrania–exencephaly–anencephaly sequence is the progression from a relatively normal-appearing exposed brain due to an absent cranium (acrania) to an amorphous brain mass (exencephaly) to no recognisable brain tissue (anencephaly) 1."

"Acrania exposes the brain to the amniotic fluid with a risk of friction with the uterine wall, placenta and fetal parts; this condition is called exencephaly 3. In this circumstance, the unprotected brain tissue undergoes progressive destruction and degeneration due to mechanical and chemical trauma, leading to complete or almost complete disappearance of the brain from 14 weeks' gestation onward. The damaged brain tissue can be seen on ultrasound as echogenic particles in the amniotic fluid 4."
