If a person is experiencing migraine without any other symptoms, it is unlikely a result of low-lying cerebellar tonsils. Outcome of Chiari-associated syringomyelia after hindbrain decompression in children: analysis of 49 consecutive cases. The degree of tonsillar descent is determined by first drawing a line from the basionto the opisthion (anterior margin to the posterior margin of the foramen magnum); this defines the plane of the foramen magnum. Prof. Hans Chiari first described this type of abnormalities of the brain that are found at the juncture of the skull. Cerebellar tonsillar ectopia. Researchers have determined that some individuals with a Chiari malformation have minimal or no herniation of the cerebellar tonsils through the foramen magnum. 5. Due to hematoma formation, the pressure in the cranium called intracranial pressure increases causing cerebellar tonsillar ectopia. Regular monitoring, medications and surgery are treatment options. Abnormalities that affect the upper cervical portion of the spine, such as basilar invagination, can also cause a Chiari malformation. A tonsillar herniation is characterized by the descent of the cerebellar tonsils through the foramen magnum, which compresses the medulla against the clivus/odontoid process. Consequently, this pressure imbalance is theorized to suck or draw the cerebellar tonsils downward through the foramen magnum. The likelihood of becoming symptomatic is proportional to the degree of descent of the tonsils. https://www.uptodate.com/contents/search. Traditionally, Chiari malformations have been defined and classified by how much of the cerebellar tonsils protrude through the foramen magnum.

This type of CM is referred to as acquired or secondary CM. NORD is a registered 501(c)(3) charity organization. 4. Consequently, this form is sometimes referred to as adult Chiari malformation. Brain growth causes pressure and crowding, which in turn pushes the cerebellar tonsils into the spinal canal. Doctors categorize Chiari malformation into three types, depending on the anatomy of the brain tissue that is displaced into the spinal canal and whether developmental problems of the brain or spine are present. In others, there may be no associated symptoms, and no intervention is necessary. Elsevier; 2018. https://www.clinicalkey.com. Is cerebellar tonsillar ectopia life threatening?

Severe headaches are counted as the conventional symptoms of this condition but some other signs are also experienced including; Neck pain Imbalanced walking or unsteady gait Poor limbs coordination with fine motor skills Tingling in the limbs Numbness in the limbs Dizziness Difficulty in swallowing often leading to gagging, choking and vomiting Low-lying cerebellar tonsils, or CMs, are rare. The cerebellum controls key behaviors that affect motor functions, such as coordination, balance, vision, and speech. Ketonen L, Hiwatashi A, Sidhu R. Pediatric brain and spine, an atlas of MRI and spectroscopy. When the tonsils protrude through the foramen magnum, they block the proper flow of cerebrospinal fluid between the skull and the spinal cord, potentially compressing the brainstem (pons medulla) and the upper portion of the spinal cord. https://www.ninds.nih.gov/Disorders/Patient-Caregiver-Education/Fact-Sheets/Chiari-Malformation-Fact-Sheet. Chiari malformations can also occur as part of a larger syndrome such as Goldenhar syndrome, Albright hereditary osteodystrophy (pseudohypoparathyroidism), Hajdu-Cheney syndrome, achondroplasia and hereditary connective tissue diseases such as Ehlers-Danlos syndrome.
