Chiari II malformation (CM-II), commonly known as Arnold-Chiari malformation, is a relatively common congenital malformation characterized by beaked midbrain, downward displacement of the tonsils, and cerebellar vermis, and spinal myelomeningocele.

What is the difference between Type 1 and Type 2 Chiari malformation?

There are two main kinds of Chiari malformations. Type 1 Chiari malformation symptoms and signs can show up in infants, children, teens or adults. Type 2 Chiari malformation is associated with spina bifida and is present at birth. Surgery can address symptoms such as headache, hydrocephalus, sleep apnea and others.

Is Arnold-Chiari spina bifida?

Spina bifida is the incomplete development of the spinal cord and/or its protective covering. Type II is also known as "classic" Chiari malformation or Arnold-Chiari malformation. In type II Chiari malformation, both the cerebellum and the brain stem extend into the foramen magnum.

Is Arnold Chiari syndrome?

A Chiari malformation, previously called an Arnold-Chiari malformation, is where the lower part of the brain pushes down into the spinal canal.

What causes Chiari II malformation?

Disease at a Glance While the severity of CM type II can vary greatly, it can potentially cause serious complications during infancy or childhood. The exact cause of CM type II is not known but it appears to be due to defects in the brain and spinal cord that occur during fetal development.

What is Arnold Chiari type1?

Chiari malformation type 1 occurs when the section of the skull containing a part of the brain (cerebellum) is too small or is deformed, thus putting pressure on and crowding the brain. The lower part of the cerebellum (tonsils) is displaced into the upper spinal canal.

What is the result of a Chiari Type II malformation associated with a myelomeningocele?

Type II Chiari malformation This type occurs almost exclusively in patients with myelomeningocele. Myelomeningocele is a congenital condition in which the spinal cord and column do not close properly during fetal development, resulting in an open spinal cord defect at birth.

Is Chiari malformation type 2 fatal?

A CM can block the normal flow of this fluid and cause pressure within the head that can result in mental impairment and/or an enlarged or misshapen skull. Severe hydrocephalus, if left untreated, can be fatal. Hydrocephalus can occur with any type of Chiari malformation, but is most commonly associated with Type II.

How is Arnold Chiari malformation diagnosed?

Tests may include:Magnetic resonance imaging (MRI). An MRI is often used to diagnose Chiari malformation. An MRI uses powerful radio waves and magnets to create a detailed view of the body. ... Computerized tomography (CT) scan. Your doctor may recommend other imaging tests such as a CT scan.
