Prenatal diagnosis of retinal detachment in Walker-Warburg syndrome.

Lissencephaly, hydrocephalus, and eye abnormalities characterize patients with the Walker-Warburg syndrome, an uncommon autosomal recessive condition. Encephaloceles occur in about 50% of patients. We describe the prenatal diagnosis of this condition based on the ultrasonographic findings of retinal detachment, hydrocephalus, and an encephalocele in a fetus not known to be at risk.
