Other conditions sometimes causally associated with Chiari malformation include hydrocephalus, [49] syringomyelia, spinal curvature, tethered spinal cord syndrome, and connective tissue disorders [42] such as Ehlers–Danlos syndrome [50] and Marfan syndrome. Chiari malformation is the most frequently used term for this set of conditions.
The first major form relates to an abnormality of the brain called an Arnold–Chiari malformation or Chiari malformation. This is the most common cause of syringomyelia, where the anatomic abnormality, which may be due to a small posterior fossa, causes the lower part of the cerebellum to protrude from its normal location in the back of the ...
Tethered cord syndrome (TCS) refers to a group of neurological disorders that relate to malformations of the spinal cord. [1] Various forms include tight filum terminale, lipomeningomyelocele, split cord malformations (diastematomyelia), occult, dermal sinus tracts, and dermoids.
Chiari malformation (CMI) is when the cerebellar tonsils push through the foramen magnum of the skull. CSF flow varies based on level of tonsil descent and type of Chiari malformation, so the MRI can also be helpful in deciding the type of surgery to be performed and monitoring progress. [ 8 ]
Cervicocranial syndrome is either congenital [1] or acquired. [2] Cervicocranial syndrome may be caused by Chiari disease, Klippel-Feil malformation, [3] osteoarthritis, and physical trauma. [4] Treatment options include neck braces, pain medication and surgery. The quality of life for individuals suffering from Cervicocranial syndrome can ...
Craniocervical instability is more common in people with a connective tissue disease, including Ehlers-Danlos syndromes, [1] osteogenesis imperfecta, and rheumatoid arthritis. [2] It is frequently co-morbid with atlanto-axial joint instability, Chiari malformation , [ 3 ] or tethered spinal cord syndrome .
At least ½ of syrinxes occur in patients with congenital abnormalities of the craniocervical junction (e.g. herniation of cerebellar tissue into the spinal canal, called Chiari malformation), [1] brain (e.g. encephalocele), or spinal cord (e.g. myelomeningocele—see Congenital Neurologic Anomalies: Brain Anomalies). For unknown reasons, these ...
The Chiari Institute is a medical institution that focuses on the treatment of Arnold–Chiari malformation and syringomyelia. It was established in 2001 by the North Shore-LIJ Health System , and is located in Great Neck, New York . [ 1 ]
