Specific Types & Syndromes
Hydrocephalus in Chiari II malformation
Hydrocephalus in Chiari II malformation is the hydrocephalus that frequently accompanies Chiari II, the malformation associated with spina bifida.
In short: Hydrocephalus in Chiari II malformation
- It accompanies Chiari II malformation, linked to spina bifida.
- The malformation disrupts CSF flow and outlets.
- It is commonly treated with a shunt.
- It is part of caring for children with spina bifida.
What it is
Hydrocephalus in Chiari II malformation refers to the hydrocephalus that frequently accompanies Chiari II — the malformation, associated with spina bifida, in which hindbrain structures are displaced downward toward the spinal canal. The displacement disrupts CSF flow.
Understanding Hydrocephalus in Chiari II malformation
In Chiari II, the downward displacement of hindbrain structures can obstruct the flow and outlets of CSF, commonly leading to hydrocephalus. Because Chiari II is almost always linked to spina bifida (myelomeningocele), this hydrocephalus is a frequent feature in children with spina bifida and is commonly treated with a shunt. The interplay between Chiari II, spina bifida, and hydrocephalus is important: managing the hydrocephalus is part of comprehensive care, and the team monitors for it and for any related changes over time.
Why it matters
Understanding hydrocephalus in Chiari II helps families see how this malformation disrupts CSF flow to cause hydrocephalus, and why it is a common, managed feature in children with spina bifida.
Common questions
Why does Chiari II cause hydrocephalus?
It disrupts CSF flow and outlets through downward displacement of hindbrain structures.
Is it linked to spina bifida?
Yes — Chiari II is associated with spina bifida.
How is it treated?
Commonly with a shunt.
Bottom line
Hydrocephalus in Chiari II malformation frequently accompanies this spina-bifida-linked malformation and is commonly treated with a shunt.
