What Is Dandy Walker Syndrome?
Reviewed: Dr. Mera
2. Characteristics
A key feature of Dandy-Walker syndrome is the absence or underdevelopment of the cerebellar vermis. This is the middle part of the cerebellum, that connects both cerebellar hemispheres. Its function is associated with bodily posture and locomotion.
Other key features of this syndrome include enlargement of the posterior fossa (base of the skull) and enlargement of the 4th ventricle. Moreover, the buildup of fluid in the spaces that surround the brain can also occur (hydrocephalus). This can cause an expansion of the skull, and it can also lead to an increase in pressure on the brain, which is likely to lead to further problems.
