Not Dandy –Walker variant: a review of prominent retrocerebellar cerebrospinal space in children

The prominent retrocerebellar cerebrospinal fluid (CSF) space can be frequently encountered on paediatric neuroimaging studies. In cases involving abnormal vermian development where imaging does not align with the established criteria of Dandy –Walker malformation (DWM), the term “Dandy–Walker variant or continuum” has been historically employed to describe the aberrant posterior fossa development. Instead, the emphasis is on a more elaborate description of the findings in the posterior fossa. Moreover, combining the findings in t he supratentorial brain can occasionally predict certain neurogenetic disorders that mimic Dandy–Walker phenotype.
