Can cerebellar tonsils cause migraines?
Chiari malformation is a medical condition characterized by cerebellar tonsillar herniation of ≥5 mm below the level of the foramen magnum and is a known rare cause of adult-onset headaches.
Can Chiari malformation cause migraines?
The most common symptom associated with a Chiari malformation is occipital headaches. These headaches are felt near the base of the skull and may radiate to cause pain in the neck and shoulders. They can be severe and may be described as sharp, brief, throbbing or pulsating.
Does Chiari malformation affect pregnancy?
Conclusions: Offering normal vaginal delivery with effective analgesia, for women with Chiari malformation, appears to be safe. Pregnancy care should be provided by a multi-disciplinary team with experience in managing Chiari malformation.
What are symptoms of low-lying cerebellar tonsils?
Patients often have symptoms worsened by coughing, sneezing, or straining. Additional symptoms include posterior cervical pain, balance issues, difficulties with speaking or swallowing, or tingling and burning sensations within the fingers, toes, or lips.
What does low-lying cerebellar tonsils mean?
Low-lying tonsils, sometimes also called benign tonsillar ectopia, is a subtype of cerebellar tonsillar ectopia denoting asymptomatic and only slight downward descent of the cerebellar tonsils through the foramen magnum and is distinct from Chiari I malformations.
What does it mean to have low lying cerebellar tonsils?
Can Chiari cause seizures?
In patients with Chiari malformation type 1 (CMI), epileptic seizures are occasionally reported both in symptomatic patients candidate to surgery and in patients without symptoms of tonsillar displacement in whom CM1 is often an incidental finding in the diagnostic work up for idiopathic epilepsies.
How do you fix low-lying cerebellar tonsils?
The most common surgery to treat Cerebellar Tonsillar Ectopia is posterior fossa decompression surgery. This procedure relieves pressure and compression on the brainstem by removing small pieces of bone in the posterior skull, and in turn enlarges the foramen magnum.

What causes a headache in the cerebellar tonsil?
Chiari malformation. Herniation of the cerebellar tonsils through the foramen magnum is a well-described cause of headache. These are typically impulse headaches, precipitated by coughing or straining. They are usually occipital in location.
What’s the difference between benign and low lying tonsils?
Typically a descent of less than 3-5 mm is used, however, this varies from author to author, and is discussed further in the article on Chiari I malformation . Low-lying tonsils are the preferred term over benign tonsillar ectopia as not all individuals with <5 mm tonsillar ectopia are asymptomatic 1.
Where is the ectopia of the cerebellar tonsils?
Cerebellar tonsillar ectopia denotes an inferior location of the cerebellar tonsils below the margins of the foramen magnum. It, therefore, encompasses both minor asymptomatic tonsilar ectopia and Chiari I malformations.
