Hans von Chiari, Professor of Morbid Anatomy at Charles University in Prague, 1891 published a his findings describing three cases with malformations of the lower part of the cerebellum and brain stem. type I, II, and III. These were later, named the Chiari malformations in his honor.
In the Chiari malformation Type I (the cerebellar tonsils herniate down into the upper cervical spinal canal with the lower brain stem sometimes hanging down into the spinal canal. Type II has the lower brain stem, cerebellar vermis, and tonsils hanging down below the foramen magnum. Type III malformation has the tissues of the posterior fossa displaced into a soft sac (meningocele) at the back of the head and upper neck.
Austrian pathologist Hans Chiariin the late 19th century.
An Arnold-Chiari malformation is an alternative name for a Chiari malformation, a malformation of the brain consisting of a downward displacement of the cerebellar tonsils through the foramen magnum.
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.
Chiari malformation is curable by surgery.
The Arnold-Chiari syndrome is a rare malformation of the brain. See also the link below.
chiari affects 1 in 1,000 people.
yes.
yes it is. but not all children may inherit the malformation,

Arnold Chiari malformation
Long-term prognosis for persons with Arnold-Chiari I malformations is excellent. Full recovery from surgery may take several months.
An Arnold-Chiari malformation is diagnosed with magnetic resonance imaging (MRI) . An MRI uses magnetism and radio waves to produce a picture of the brain and show the crowding of the space between the brain and spinal cord.
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.
