摘要
目的:探讨前脑无裂畸形的影像学表现特点。方法:回顾性分析4例前脑无裂畸形的CT、MRI特征。结果:4例患者双侧大脑半球不同程度的无分离,大脑深部皮质核团、间脑及大脑外侧裂的位置形态有不同程度的发育异常。其异常程度随着前脑无裂畸形严重程度的增加而增加。结论:CT和MRI可以清楚的显示前脑无裂畸形患儿的脑发育情况,评价其畸形的严重程度。
Objective:To analyze the imaging characteristics of prosencephalicephaly.Methods:There were 4 cases of prosencephaly. Their CT and MRI findings were analysed retrospectively. Results: Partial noncleavage of the middle interhemispheric in different level were found in all four patients. The deep gray nuclear, thalami and sylvian were developed anomaly. The deep brain structures and sylvian were affected severity of prosencephaly. Conclusion: CT and MRI can show the developmental condition of prosencephaly clearly. The malformation severity of prosencephalic can be estimated by the deep gray nuclear,thalami and sylvian.
