脑裂畸形的CT诊断

CT Diagnosis of Schizencephaly

分析脑裂畸形CT表现的特点。材料和方法：搜集经CT检查发现的脑裂畸形18例。其中男11例、女7例；儿童16例，年龄从6个月～10岁，平均2．9岁；成人2例，分别为33岁和45岁。结果：本组中单侧性脑裂畸形13例，占722％；双侧性5例，占27．8％；单侧性更多见。脑裂畸形分闭唇型和开唇型两种。在13例单侧性脑裂畸形中闭唇型（9／13，692％）更多见；而在5例双侧性中开唇型（9／10，90％）占优势。在18例脑裂畸形中共有23个脑裂，其中开唇型（13／23，56．5％）稍多于闭唇型（10／23，43．5％）。结论：CT不仅能正确地诊断脑裂畸形，而且可对其分型、指出病变的严重程度、估计脑裂畸形患者的预后，对优生学也是有帮助的。

To analyse the CT features of schizencephaly. Materials and methods: 18 cases of schizencephaly with CT studies included eleven males and seven females. Age extended from 6 months to 10years, mean 2.9 years, including 16 children, and the other 2 were 33 years and 45 years of age respectively. Results: In this series of schizencephaly, there were 13 cases of unilateral form (13/18,72. 2 % ) and 5 cases of bilateral form (5/18, 27. 8% ). In 13 cases of unilateral form belonging to the closed lip tape which was frequently happened (9/13, 69. 2% ) and in 5 cases of bilateral form belonging to the open lip type was considered as the dominant (9/10, 90% ). In 18 cases of schizencephaly tEers were 23clefts, the type of open lips (13/23, 56. 5% ) was slightly more frequent than the type of closed lip (10/23, 43. 5% ). Conclusion: CT not only can correctly diagnose schizencephaly but also can make classification, figures out its seventy and estimates the prognosis helpful for eugenics.
