Chiari malformation

Also known as: Arnold-Chiari malformation
Arnold-Chiari malformation is a rare malformation of the brain that is sometimes, but not always, apparent at birth. It is characterized by abnormalities in the area where the brain and spinal cord meet that cause part of the cerebellum to protrude through the bottom of the skull (foramen magnum) into the spinal canal. This interferes with the flow of cerebral spinal fluid to and from the brain, leading to accumulation of cerebral spinal fluid in the empty spaces of the spine and brain. The portion of the cerebellum that protrudes into the spinal canal can become elongated and is called the "cerebellar tonsils" because it resembles the tonsils.
