- Type 1 a small portion of the cerebellum has extended into the spinal canal, usually develops as the skull and brain are growing
- Type 2 both the cerebellum and brain stem have extended into the spinal canal, this form is present at birth and usually associated with Spina Bifida and Hydrocephalus.
- Type 3 is rare and severe, both the cerebellum and brain stem have extended all the way to the spinal cord, this type has a high mortality rate
- Type 4 involves an incomplete or underdeveloped cerebellum, usually associated with anencephaly, this type has a high mortality rate
Chiari malformation is a (usually) congenital condition that results in herniation of the cerebellar tonsils through the foramen magnum (hole in the bottom of your skull in which the spinal cord enters/exits). There are several types of Chiari malformation, and treatment is based on the type of malformation present.

What is the difference between an Arnold Chiari Malformation and Chiari Malformation?
An AVM is an arteriovenous malformation, so it is a malformation that connects arteries and veins, while a Chiari Malformation (more commonly referred to as an Arnold-Chiari Malformation) is one where part of the brain herniates (pushes through) the base of the skull.
Is Arnold Chiari curable in adults?
Chiari malformation is curable by surgery.
Is ms same as chiari malformation?
no
What is karie malformation?
The closest match for karie malformation is Chiari malformation. When the brain tissue spreads down into a person's spinal cord, this is called Chiari malformation. Treatment is available, but is not needed in some cases.
How common is Arnold-Chiari malformation?
chiari affects 1 in 1,000 people.
Is chiari malformation classed as a disability?
yes
What is kary?
The closest match for karie malformation is Chiari malformation. When the brain tissue spreads down into a person's spinal cord, this is called Chiari malformation. Treatment is available, but is not needed in some cases.
Is chiari 1 malformation also known as hydrocephalus?
No, but chiari malformation can cause hydrocephalus. In chiari malformation, the hindbrain sits low. This can constrict the normal passageways for CSF (cerebral spinal fluid). If the CSF can't flow properly, it builds up. This is known as hydrocephalus.
What is an Arnold-Chiari malformation?
Arnold-Chiari malformation is a condition where the brain tissue extends into the spinal canal. This can disrupt the flow of cerebrospinal fluid, causing symptoms like headaches, dizziness, and difficulty walking. Treatment may involve surgery to relieve pressure on the brain and spinal cord.
Will having operation for Arnold chiari malformation cure the situation?
There is NO CURE for ANY type of Chiari malformation. Chiari 1 doesn't carry the same abnormal structure to the brain as Chiari 2 or 3 do. Decompression surgery might and only might help relieve some symptoms. There are a percentage of people who return to stable lifestyle, there are more who can't. again, THERE IS NO CURE for Chiari Malformation.
What is a Chiari malformation?
Chiari II anomaly-- A structural abnormality of the lower portion of the brain (cerebellum and brain stem) associated with spina bifida. The lower structures of the brain are crowded and may be forced into the foramen magnum.
What are the symptoms of a Chiari malformation?
The symptoms of a Chiari malformation may include muscle weakness, balance issues and pain. Many individuals do not have symptoms and the only to confirm is by laboratory tests.
