Arnold chiari malformation may be classified according to herniation content into 4 subtypes. Type 1 has herniation of cerebellar tonsils. Type 2 has herniation of cerebellar tonsils and vermis. Type 3 has herniation of Cerebellar tonsil and vermins and lower brain stem. Type 4 has cerebellar hypoplasia with brain stem in posterior fossa. | |||

Overview
Arnold chiari malformation may be classified according to herniation content into 4 subtypes. Type 1 has herniation of cerebellar tonsils. Type 2 has herniation of cerebellar tonsils and vermis. Type 3 has herniation of Cerebellar tonsil and vermins and lower brain stem. Type 4 has cerebellar hypoplasia with brain stem in posterior fossa.
Classification
Arnold chiari malformation may be classified according to herniation content into 4 subtypes:[1]
| Subtypes | Explanation | Association |
|---|---|---|
| Type1 | Herniation parts: Cerebellar tonsils
|
Syringomyelia |
| Type 2 | Herniation parts: Cerebellar tonsils and vermis
|
Lumbosacral myelomeningocele |
| Type 3 | Herniation parts: Cerebellar tonsil and vermins, lower brain stem
|
Occipital encephalocele |
| Type 4 | Herniation parts: Brain stem located in posterior fossa, underdeveloped cerebellum
|
A variation of cerebellar hypoplasia |
