摘要
Abstract
Objective To explore the value of detection of cerebellar cistem width with MRI in evaluating fetal posterior fossa abnormality.Methods A total of 189 pregnant women (24-36 gestational weeks) suspected with abnormal development of fetal posterior fossa in our hospital were selected and received MRI examination to analyze the impact of cerebellar cistem width on the developmental malformation of posterior fossa and the prognosis.Results Among the 189 fetus,there were 69,88 and 32 fetus with a cerebellar cistern width ＜8.0,8-10 and ＞10 mm respectively.There were 27 cases of pure cerebellar cistern expansion and five cases of non-pure cerebellar cistern expansion (one case of cistema magna arachnoid cyst and four cases of Danva's malformation) among those ＞ 10mm.According to postpartum ultrasound or MRI follow-up visit,in the groups ＜8.0,8-10 and ＞ 10 mm,there were two cases (2.9％),five cases (5.7％) and 10 cases (31.3％) of posterior fossa malformation respectively.The proportion of posterior fossa malformation in ＞10 mm group was significantly higher than that in the groups ＜8.0 and 8-10 (P ＜ 0.05).The postpartum gross motor,fine activity,cognitive function,language function and social function scores in fetus in the groups ＜8.0,8-10 and ＞ 10 mm were from high to low,showing statistical difference (P ＜ 0.05).Conclusion MRI can clearly show the structure of cerebellar cistern and carry out accurate radial line measurement.When the cerebellar cistern width is increased to ＞10 mm,the probability of malformation and poor postpartum development is markedly increased.关键词
