Anencephaly in Dichorionic Diamniotic Twin Pregnancy: One Case Report.

Neural Tube Defects (NTDs) are birth defects caused by failure of the neural tube to close completely, resulting in incomplete formation of the brain or spinal. The two most common types of NTDs are anencephaly and spina bifida.

Anencephaly or cranium bifida also referred as acrania is a characterized by absence of the conception of the skull, scalp and the brain. This defect can be diagnosed during antenatal period during ultrasound morphological routine test. In our case, it's an unattended twin pregnancy in a multiparous patient who came for a usual ultrasound morphological test. The sonographic scan finds out an uncompleted cranial neural tube with a totally absent brain and skull, type anencephaly.
