目的通过分析胎儿侧脑室形态异常的MRI表现,为临床产前诊断及预后判断提供有效的信息。方法回顾性分析39例因病或因畸所致侧脑室形态异常的胎儿颅脑MRI资料。结果 39例胎儿中胼胝体发育不全21例,脑穿通畸形或脑室旁软化灶13例(单侧者5例,双侧者8例),脑室旁-脑室内出血2例,憩室性畸形2例(透明隔缺如1例,单脑叶型前脑无裂1例),Dandy-Walker畸形1例。结论胎儿侧脑室形态的改变的特点对诊断颅脑疾病或畸形具有重要的价值。
Objective To provide effective information for clinical prenatal diagnosis and prognosis by analyzing the MRI manifestations of abnormal fetal lateral ventricle morphology. Methods A retrospective analysis of 39 cases of fetal brain abnormalities caused by disease or abnormal fetal brain MRI data. Results Thirty-one fetuses had 21 cases of hypoplasia of corpus callosum, 13 cases of penetrating deformities or perivascular soft tissues (5 cases on one side and 8 cases on both sides), 2 cases of ventricular-ventricular hemorrhage, 2 cases of diverticular deformity 1 case of septum defect, 1 case of single brain lobar type forebrain without fissure), 1 case of Dandy-Walker malformation. Conclusion The characteristics of fetal lateral ventricle morphological changes have important value in the diagnosis of craniocerebral disease or deformity.
