Anencephaly
Updates to Study Attributes
On ultrasound examination of the fetus fetus, the fetal skull bonescalvaria and brain parenchyma were not not visualized. Biparietal diameter and head circumference could not be measured.
A coronal"coronal" section through the fetal face was showing a 'frog' likeshows frog-like bulging of eyes and absent frontal bones.
The transvaginal scan (TVS) demonstrates the fetus in sagittal view.

Updates to Case Attributes
Anencephaly is a lethal lethal congenital anomaly which can be detected on ultrasound as early as 11 11 weeks of gestation.
If some amount of neural tissue is present this, the condition is termed exencephaly.
Polyhydramnios is usually associated with neural tube defects. Associated anomalies should be sought, including spinal dysraphismsdysraphism, diaphragmatic herniashernia and amniotic band syndrome.
Maternal serum alpha feto protein-fetoprotein levels are raised in all types of neural tube defects.
Folic acid supplements infor women of reproductive age group isare helpful for the prevention of neural tube defects. No treatment option is available for anencephaly.
