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. Type ii is usually associated with a failure of the spinal cord to close and is often associated with hydrocephalus. ...Read moreSee 1 more doctor answer
I have an chiari malformation type 1. What symptoms would I have if I am not circulating enough csf? I have a MRI in two weeks to see.
Shoulder area numb: The lack of CSF flow around the chiari area is thought to raise the risk for a fluid collection inside the cervical spine called a syrinx. This can cause arm/hand symptoms with some numbness in a shawl pattern across the shoulder area. An MRI through your cervical spine should show this fluid collection if it is there. It can be followed after the chiari is decompressed usually resolving by itself. ...Read moreSee 1 more doctor answer

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
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
Can be symptomatic: Chiari malformation type i is neurological disorder where cerebellum (or more specifically the cerebellar tonsils), descends out of the skull into the spinal area, resulting in compression of parts of brain and spinal cord, and disrupts normal flow of cerebrospinal fluid.Type ii involves extension of both cerebellar and brain stem tissue into the foramen magnum. Associated with myelomeningocele. ...Read more
