Chiari Malformation
Chiari malformation is a condition in which part of the cerebellum extends through the opening at the base of the skull into the spinal canal. This can disrupt the normal flow of cerebrospinal fluid (CSF) and place pressure on the brain and spinal cord, leading to a variety of neurological symptoms.
Common Causes of Chiari Malformation
Chiari malformation is most commonly congenital, meaning it develops before birth as the skull and brain form. In some cases, it may develop later in life due to conditions that affect cerebrospinal fluid flow or pressure.
Common Symptoms:
-
Headaches
-
Neck pain
-
Dizziness or balance problems
-
Numbness or tingling in the arms or legs
-
Muscle weakness
-
Difficulty swallowing
-
Vision changes
How Can It Be Treated?
Treatment depends on the severity of symptoms and the underlying anatomy. Options may include observation, symptom management, or surgical treatment such as posterior fossa decompression to relieve pressure and improve cerebrospinal fluid flow.
