Objectives: After studying the article entitled “Dandy-Walker Malformation With Concomitant Agenesis of the Corpus Callosum as Investigated by Neonatal Sonography,” you will be able to:
Understand Dandy-Walker malformation and associated abnormalities
Identify sonographic markers of Dandy-Walker malformation, agenesis of the corpus callosum, and associated abnormalities
Recognize the importance of both prenatal and neonatal sonography and corresponding MRI in the diagnosis of Dandy-Walker malformation and agenesis of the corpus callosum
What is the most common corresponding deficiency seen with Dandy-Walker malformation? Spina bifida Agenesis of the corpus callosum Arnold-Chiari malformation Anencephaly
Organogenesis of the vermis and the cerebellum is complete by what gestational age? End of 8th week End of 11th week End of 15th week End of 18th week
What is the overarching term that is offered for the many variants that are associated with Dandy-Walker malformation? Agenesis of the corpus callosum Dandy-Walker complex Dandy-Walker anomalies Agenesis of cerebellum
When Dandy-Walker malformation is diagnosed in utero, which sonographic view of the posterior fossa is typically used? Axial views Sagittal views Coronal views Profile views
Agenesis of the corpus callosum is demonstrated by abnormal spacing of the lateral ventricles, creating what symbol in coronal imaging? Banana Lemon Heart Longhorn
