Occipital Encephalocele: Fetal MRI

MRI role is to evaluate the fetal brain, particularly when an abnormality has been detected on prenatal US or when a fetus is at increased risk for neurodevelopmental anomalies. Fetal MRI has higher contrast resolution, is not affected by the shadowing from the calvarium or by low amniotic fluid volume, allows a larger field of view and can easily be performed using ultrafast T2-W sequences, making it more useful than US in late pregnancy. This patient shows bony defect in the occipital bone with associated encephalocele.
