【Abstract】 Objective:To analyze the CT findings of schizencephaly.Methods:CT findings of 17 cases of schizen cephaly were analyzed retrospectively.There were 11 males and 6 females.The age ranged from 8 months to 29 years,thirteen patients were under the age of 10 years.Results:The characteristic CT finding of schizencephaly was a transcerebral cleft which was lined by gray matter.There were unilateral clefts in 14 cases and bilateral in 3.Totally there were 20 clefts.The fused type (type Ⅰ) was observed in 10 cases,and the open type (type Ⅱ) also in 10 cases.Accompanying abnormalities included absence of the septum pellucidum (12 cases),dysplasia of the corpus callosum (1 case),general pachygyria (1 case),and a small cystoid dilatation at medial end of the cleft (1 case).Conclusion:CT can well show schizencephaly and associated abnormalities.更多还原
