Imaging Findings

The obstetric ultrasound images of the fetal face demonstrate a single midline orbit (Figure 1). Axial imaging of the fetal brain shows fused thalami (Figure 2). Coronal imaging of the brain (Figure 3) demonstrates a monoventrical with lack of interhemispheric fissure and falx cerebri. At birth a single midline orbit and a probiscus were present. The baby died shortly after birth. An autopsy was not performed and no chromosomal evaluation was undertaken.
