Cerebral abnormalities in the Neu-Laxova syndrome

Cerebral abnormalities are considered an obligatory manifestation of the Neu-Laxova syndrome and include lissencephaly, severe microcephaly, aplasia of the corpus callosum, hypoplasia of the cerebellum, and other pathological changes. We present data on 3 cases with central nervous system anomalies, two of which have not been described previously, and summarize the literature on the subject. The problem of distinguishing type III lissencephaly is discussed.
