Craniorachischisis with Exencephaly.

Neural tube defects can be as mild as spina bifida, to as severe as anencephaly, with only a fraction of these cases presenting as both craniorachischisis and exencephaly. The G3, P1011 mother was 25-years old, who at an estimated fetal gestational age of 17 weeks had a fetal diagnosis of anencephaly based on a sonogram, resulting in elective pregnancy termination. The female fetus had an open neural tube defect, consisting of craniorachischisis and exencephaly. No abnormalities were noted in any other organs. Although mostly associated with anencephaly, craniorachischisis can also be associated with exencephaly in early pregnancy.
