Abstract
Walker-Warburg Syndrome (WWS) is a rare and severe form of autosomal recessive congenital
muscular dystrophy affecting the brain, eyes, and muscles. We report a case of an
infant diagnosed with cobblestone lissencephaly as well as a Chiari malformation,
consistent with likely WWS based on fetal anomalies noted on prenatal ultrasound and
confirmed with magnetic resonance imaging (MRI) at 35 week. Although multiple posterior
fossa abnormalities have been reported in the setting of WWS, to our knowledge, the
co-existence of a Chiari malformation has never before been reported. We describe
the fetal MRI and pathological findings of WWS and discuss the role of MRI as an antenatal
imaging tool.
