چکیده
Holoprosencephaly is a brain malformation that develops as a result of a defect in development of prosencephalon during early gestation. Holoprosencephaly can be diagnosed with prenatal ultrasonography and magnetic resonance imaging. We report herein a case with cyclopia and holoprosencephaly detected by prenatal ultrasonography.

We report on the ultrasound (US) detection of holoprosencephaly with cyclopia at a gestational age of 16 weeks. The sonographic diagnosis was based on the intracranial finding of fused thalami with no visible midline structures and facial abnormalities, including cyclopia and proboscis. We evaluated the fetal face by 3-dimensional (3D) transabdominal US and were able to identify the cyclopia be...
