What Is The Difference Between Chiari Malformations I And Ii
Extent of herniation: It is the downward displacement of the cerebellum, specifically a region called the "tonsils", through the foramen magnum. There are actually 4 types. Type one is only tonsillar herniation, that is mild; type ii shows more herniation, to include a middle portion of the cerebellum. This type is often associated with an myelomeningocele (herniation of lining of the brain). ...Read moreSee 1 more doctor answer
Chiari malformations: Type i is associated with a portion of the cerebellum called the tonsils, downwardly displaced through the foramen magnum at the base of the skull. Most are asymptomatic.

Different: Arnold chiari malformation describes low lying cerebellar tonsils, and sometimes other posterior fossa abnormalities. Chiari syndrome can refer to the abnormality described above, or to budd chiari syndrome. Budd chiari syndrome has to do with clotting in the venous system of the liver and has nothing to do with arnold chiari malformation. ...Read more
Have read that people with chiari 1 malformations can have cerebellar fits. What is the difference betw. A cerebellar fit & a tonic clonic seizure?
Some differences: Cerebellar fits"characterized by drop attacks with/without deterioration of consciousness, opisthotonic posturing(head and back arching backward), and varying degrees of respiratory compromise. Cerebellar fits may mimic other disorders such as cardiogenic syncope and epileptic seizures.

The symptoms can be more difficult to pinpoint - these include headaches, fatigue, muscle weakness in the head and face, difficulty swallowing, dizziness, nausea, impaired coordination, and, in severe cases, paralysis. ...Read more
Many do not: The finding of a type one chiari malformation is often an incidental finding on MRI of no clinical significance. These do not need surgery. Surgery for the malformation is quite complex and must be considered very carefully. There are significant risks to the surgery that must outweigh the risks of not doing surgery. Second, third, and fourth opinions may be appropriate. ...Read moreSee 1 more doctor answer
Depends on activity: If you are straining and lifting heavy amounts, you could have more headaches and numbness/tingling. Some people can have dizziness and passing out with exertion. Days in which there is no exertion may be associated with less headache and other symptoms. Some patients have constant symptoms because the cerebellar position does not change for them with position or activity. ...Read moreSee 1 more doctor answer
