摘要
目的 研究先天性透明隔移位的CT表现及诊断价值。方法 CT检查透明隔移位 2 4例 ,分别测量透明隔与大脑镰及中线移位的程度。结果 2 4例中透明隔向左移位 12例 ,向右移位 12例 ,左侧脑室扩张 9例 ,右侧脑室扩张 10例。透明隔移位的测量提示透明隔偏离大脑镰及中线。结论 透明隔移位是一种轻度的先天性发育畸形 ,它多导致一侧脑室扩张 ,其重要特征是透明隔偏离大脑镰及中线。
Purpose To evaluate CT appearance and diagnostic criterion of the congenital shift of septum pellucidum. Methods The 24 cases of congenital shift of septum pellucidum were retrospectively studied by CT. Measurement included deviated distance of septum pellucidum from midline. Results The septum pellucidi in 12 of 24 cases shifted to left and other 12 cases shifted to right. The left lateral ventricles in 9 of 24 cases dilated and the right lateral ventricles dilated in other 10 cases. Measurement showed the septum pellucidi deviated from falx cerebrum and midline. Conclusion The shift of septum pellucidum is a minor congenital malformation. It results in the dilation of one side lateral ventricle in most patients. The important CT diagnostic sign is that septum pellucidum deviates from falx cerebrum and midline. [
