Chiari Malformation: Causes, Symptoms, Diagnosis, and Treatment
Chiari Malformation is a structural abnormality of the brain that affects how the brain and spinal cord connect. It occurs when brain tissue extends into the spinal canal, often due to a smaller or misshapen skull. This condition can interfere with the normal flow of cerebrospinal fluid (CSF) and may lead to a range of neurological symptoms.
What Is Chiari Malformation?
Chiari Malformation is a condition in which the cerebellum—the part of the brain responsible for balance and coordination—pushes downward through the foramen magnum (the opening at the base of the skull). This displacement can compress the brainstem and spinal cord, disrupting normal neurological function.
The condition can be present at birth (congenital) or develop later in life (acquired).
