“Dandy-Walker variant (DWv) is a less severe posterior fossa anomaly than the classic Dandy-Walker malformation (DWM), characterized as partial vermian hypoplasia with partial obstruction to the fourth ventricle. It is considered on the lesser end of the disease spectrum in the Dandy-Walker continuum.
This term was created to include those malformations that do not meet the criteria for Dandy-Walker malformation, however, some authors recommend to avoid it as there is a lack of specificity that may create some confusion. Instead, a more detailed anatomic description is recommended 4.”
