What Is Chiari Malformation
Low cerebellum.: The tip or bottom of the cerebellum, the posterior brain controlling coordination, may extend be too low, and lie behind the spper spinal cord where it can get pinched. Chiari is graded according to severity. Wickipedia has a good article on chiari malformation listing the grading. ...Read more
Can be symptomatic: Chiari malformation type i is neurological disorder where cerebellum (or more specifically the cerebellar tonsils), descends out of the skull into the spinal area, resulting in compression of parts of brain and spinal cord, and disrupts normal flow of cerebrospinal fluid.Type ii involves extension of both cerebellar and brain stem tissue into the foramen magnum. Associated with myelomeningocele. ...Read more
A brain anamoly: A chiari 1 is a malformation where a small part of the brain (the cerebellar tonsils) descends into the spinal canal and compresses the spinal cord/brain stem. The early symptom are typically headaches. As time proceeds and in more severe descended chiari's, the symptoms can include numbness, weakness, unsteadiness, visual issues, nausea, etc. See physician for an exam and discussion of surgery. ...Read more

There is a situation where two "tongues" of tissues called the cerebellar tonsils leave their normal anatomical position and herniated down through a hole at the base of the skull called the foramen magnum and can lead to compression of the brain stem. ...Read more

Normally, only the spinal cord passes through this opening.

It is: Chiari described different types of developmental defects of the cerebellum. Type 2 is associated with spina bifida, type 3 and type 4 are severe defects. You are probably talking about type 2 associated with spina bifida. It can cause breathing and swallowing problems. Treatment with surgery is controversial. ...Read more
Chiary II.: Chiari ii malformation (cm-ii), also known as arnold-chiari malformation, is a fetal condition characterized by downward displacement of the cerebellar vermis and tonsils, a brainstem malformation with beaked midbrain on neuroimaging, and a spinal myelomeningocele (open spina bifida). ...Read moreSee 1 more doctor answer
No one knows: Chiari described malformations of the cerebellum. Arnold added the defects in the brain associated with spina bifida. This became known as chiari type 2 or arnold chiari. There is kinking of the medulla and fourth ventricle, obstruction of the outlet of the fourth ventricle, peaking of brainstem, fusion of thalamus, as well as hydrocephalus and incomplete closure of spinal cord. ...Read more
Chiari: Chiari malformation is said to exist when the lowest part of the cerebellum of the brain (called the tonsils) extend below the foramen magnum (the hole in the base of the skull through which the spinal cord descend into the spine). In most cases this is of no consequence. However, minor or major symptoms are possible. This is almost always a congenital condition (you are born with it). ...Read more
