Alobar holoprosencephaly, proboscis and cyclopia in a chromosomally normal fetus: Prenatal diagnosis and fetal outcome.

ABSTRACT

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.
