Case report

A woman (G2P1), from a nonconsanguineous couple, was referred to our unit at 23rd week of pregnancy due to a neurological anomaly of the fetus. Her first sonography screening and triple test were normal. The fetus presented several anomalies:

• Unilateral anophthalmia of the right eye and moderate exophthalmia of the left eye;
• Right posterior schizencephaly;
• Agenesis of the corpus callosum;
• Moderate bilateral ventriculomegaly.

At 26th week the anomalies were confirmed by ultrasonography and an MRI. The fetal karyotype (46XX and serological tests  (Toxoplasmosis, Rubeola, CMV, Herpes, Chikungunya) were normal. The parents opted for interruption of the pregnancy at 27 weeks. The baby did not have any external anomalies. Postmortem 3D-computed tomography was done and confirmed the right orbit anomaly.
