Associated Conditions & Findings
Dandy-Walker malformation
Dandy-Walker malformation is a condition affecting the cerebellum and the fourth ventricle at the back of the brain.
In short: Dandy-Walker malformation
- It involves the posterior fossa structures.
- It can be associated with hydrocephalus.
- It can co-occur with other brain findings.
- It is identified on brain imaging.
What it is
It is a malformation of the posterior fossa involving the cerebellum and the fourth ventricle at the back of the brain. It is identified by its characteristic appearance on imaging.
Understanding Dandy-Walker malformation
As a posterior-fossa condition, it can be associated with hydrocephalus and may co-occur with other brain findings in some children. Because it involves the cerebellum and fourth ventricle, imaging of the back of the brain characterizes it, and the team monitors for associated hydrocephalus.
Why it matters
Understanding Dandy-Walker malformation helps families see why imaging examines the back of the brain and why associated hydrocephalus is monitored when this finding is present.
Common questions
What does Dandy-Walker involve?
The cerebellum and fourth ventricle.
Can it cause hydrocephalus?
It can be associated with it.
How is it found?
On brain imaging.
Bottom line
Dandy-Walker malformation affects the cerebellum and fourth ventricle and can be associated with hydrocephalus.
