Sporadic neonatal schizencephaly associated with brain calcification.

Schizencephaly rarely presents in the neonatal period. We present the case of a baby girl born with growth retardation and microcephaly who developed seizures on the 3rd day of life. There was no clinical or laboratory evidence of a congenital viral infection but brain imaging revealed widespread calcification and bilateral schizencephaly clefts. By the age of 11 months, she had developed gross psychomotor retardation.
