The value of ultrasonographic diagnosis in the fetal cerebellar vermis agenesis

Objective: To explore the diagnostic value of ultrasonographic in the fetal cerebellar vermis agenesis.Methods: The data of 47 cases with fetal cerebellar vermis agenesis diagnosed by ultrasonographic were retrospectively analyzed,which was compared with MRI imaging.Results: The ultrasonographic examination in 47 cases with cerebellar vermis agenesis were consistent with MRI diagnosis.The complete cerebellar vermis agenesis in 17 cases(combination of other malformations in 11 cases) and partial cerebellar vermis agenesis in 30 cases(combination of other malformations in 15 cases) were found.Conclusions: The ultrasonographic plays an important role in the diagnosis of the fetal cerebellar vermis agenesis,which can be used as an effective tool for screening the fetal cerebellar vermis agenesis.
