  The Chiari Institute
The Chiari Institute is the world's first comprehensive, multidisciplinary center for the management of patients suffering from Chiari malformation, a rare structural condition that affects the cerebellum; syringomyelia, a chronic disease of the spinal cord; and related disorders.
The institute is named in honor of Professor Hans Chiari, an Austrian pathologist who first described abnormalities of the brain at the junction of the skull and spine more than a century ago.
Physician members of the Chiari Institute include neurosurgeons, neurologists and neuroradiologists, as well as specialists in pain management, cardiology, respiratory physiology, neuro-opthalmology, neuro-otology, general medicine and pediatrics.

  Chiari Malformation
A Chiari malformation is a congenital (present at birth) defect in the area of the back of the head where the brain and spinal cord connect.
Type II Chiari malformations are typically seen in infants who are born with spina bifida, a neurological condition that causes a portion of the spinal cord and the surrounding structures to develop outside, instead of inside, the body.
Chiari malformation may be caused by exposure to harmful substances during fetal development or associated with genetic problems or syndromes that may have a tendency to run in families.

 FAQ
Chiari Malformation Type I (CM) is a neurological disorder where part of the brain, the cerebellum (or more specifically the cerebellar tonsils), descends out of the skull into the spinal area.
Usually, the Chiari headache is described as an intense pressure in the back of the head and is brought on, or aggravated, by exercise, straining, coughing, sneezing, laughing, bending over, or similar activities.
However, since the definition of Chiari is changing, most doctors will use a combination of reported symptoms, a neurological exam, MRI results, and their experience and judgment to determine if a person has Chiari.

 Chiari malformation in CFIDS, FMS
Chiari malformation or squeezing of spinal cord may be common in CFIDS, fibromyalgia.
The best known of these conditions is the Chiari malformation, in which the cerebellar "tonsils" (a portion of the cerebellum, shaped like the tonsils in the neck) extend several millimeters through the opening in the base of the skull (the foramen magnum) that allows the spinal cord to attach to the brain.
The Type I Chiari malformation (Type II is related to spina bifida and hydrocephalus and is found in infants) was first identified in 1891 and was considered to be rare before the development of MRI scans.

 NeurosurgeryToday.org | What is Neurosurgery | Patient Education Materials | chiari malformation
Chiari malformation is considered a congenital condition, although acquired forms of the condition have been diagnosed.
Chiari I malformations may be treated surgically with only local decompression of the overlying bones, decompression of the bones and release of the dura (a thick membrane covering the brain and spinal cord), or decompression of the bone and dura and some degree of cerebellar tissue resection.
Chiari II decompression is treated similarly, but is usually restricted to decompressing the tissues in the spinal canal and leaving the back of the skull alone.

 What is the Chiari Malformation?
It is characterized by a small or misshapen posterior fossa (the compartment in the back of the skull), a reduction in cerebrospinal fluid pathways and a protrusion of the cerebellar tonsils through the bottom of the skull (foramen magnum) into the spinal canal.
Chiari Malformations are also known as herniation of the cerebellar tonsils, cerebellar ectopia, hindbrain herniation and Arnold-Chiari malformations.
The Chiari I Malformations may also be associated with other disorders such as hydrocephalus (build up of fluid in the ventricles of the brain) or Syringomyelia.

Chiari I Malformations in children are a relatively common and misunderstood disorder of the craniovertebral junction.
By definition, a Chiari I malformation consists of herniation of the cerebellar tonsils at least 5 mm below the foramen magnum (see the MRI images below), although lesser amounts of tonsillar herniation may also lead to signs and symptoms.
Diagnosis is often delayed in patients with a Chiari I malformation, which of course is understandable considering the wide range of signs and symptoms that can be attributed to this malformation.

In cases involving a Chiari Malformation, the main goal of surgery is to provide more space for the cerebellum at the base of the skull and upper cervical spine.

 Erin - Chiari
Chiari Malformation is the name associated with a condition in which the posterior fossa cavity (lower rear portion of the skull) is malformed and/or is not large enough for the cerebellum and cerebellar tonsils - which cover the cerebellum.
Chiari can only be seen through MRI scans and is not usually seen (or diagnosed) in infants due to the low frequency of MRIs performed on infants as well as the inability of infants to communicate the symptoms.
Chiari is also present in children with diseases such as spina bifida and is a contributing factor to the symptoms seen in these children.

The Chiari II malformation is a complex congenital malformation of the brain, nearly always associated with myelomeningocele.
The hindbrain findings of Chiari II malformation are best explained with the theory of McLone and Knepper, which allows the hindbrain disorder to be conceptualized as resulting from a normal-sized cerebellum developing in an abnormally small posterior fossa with a low tentorial attachment.

 Chiari Malformation and Fibromyalgia
The Chiari malformation is a relatively common occurrence.
The determination that a Chiari malformation is causing the symptom complex is often complicated by the overlap of symptoms that are similar to some rheumatologic disorders; hence, the alleged association between the Chiari I malformation and the diagnosis of fibromyalgia (FMS) and chronic fatigue (CFS) syndrome.
Regardless of the presence or absence of an association, it is evident that the complex nature of the diagnosis and treatment of the Chiari I malformation and syringomyelia deserves a comprehensive and methodological approach.

 Chiari Malformation Fact Sheet: National Institute of Neurological Disorders and Stroke (NINDS)
Chiari malformations (CMs) are structural defects in the cerebellum, the part of the brain that controls balance.
Normally the cerebellum and parts of the brainstem sit in an indented space at the lower rear of the skull, above the foramen magnum (a funnel-like opening to the spinal canal).
CMs may develop when the bony space is smaller than normal, causing the cerebellum and brainstem to be pushed downward into the foramen magnum and into the upper spinal canal.
