Introduction to Arnold Chiari Malformation
Arnold Chiari Malformation (ACM) is a defect in the cerebellum. This part of the brain controls balance. It happens when the cerebellum goes into the spinal canal because of a small or odd-shaped skull. This can lead to many problems and is found with special imaging.
What is Arnold Chiari Malformation?
Arnold Chiari Malformation is when brain tissue goes into the spinal canal. It happens if the skull is too small or shaped wrong, pushing the brain down. Doctors use imaging to find out if someone has it, including arnold chiari malformation ultrasound.
Types of Chiari Malformations
There are four main types of Chiari Malformations, named Type I to Type IV:
- Type I: The most common type, where the lower part of the cerebellum, but not the brain stem, extends into the foramen magnum.
- Type II: Also known as Arnold-Chiari Malformation, involves a greater amount of brain tissue being pushed into the spinal canal and is often associated with myelomeningocele, a form of spina bifida.
- Type III: A severe form where the cerebellum and brain stem herniate into the spinal canal. This type is quite rare.
- Type IV: Involves an incomplete or underdeveloped cerebellum and is the rarest and most severe form of the condition.
Symptoms and Signs
Symptoms of Arnold Chiari Malformation vary a lot. They depend on the type and how bad it is. Common signs include:
- Headaches, often made worse by coughing, sneezing, or straining.
- Neck pain, especially at the base of the skull.
