WebThis birth defect can occur as an isolated condition or combined with other cerebral abnormalities, including Arnold-Chiari malformation, Dandy-Walker syndrome, schizencephaly (clefts or deep divisions in brain tissue), and holoprosencephaly (failure of the forebrain to divide into lobes.) Symptoms of Schizencephaly may include seizures, paralysis, and developmental delays. There are no reports of schizencephaly identified by ultrasound before 20 weeks' gestation, in contrast to other brain abnormalities arising in the first trimester, such as holoprosencephaly, which has been identified as early as 9 weeks' gestation 5-7.The small number of cases so far identified antenatally before 23 weeks' gestation all seem to have Our Information Specialists are available to you by phone or by filling out our contact form.
