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.
Radionuclide cisternography may be used to diagnose a spinal cerebrospinal fluid leak. CSF pressure is measured and imaged over 24 hours. [2] A radionuclide (radioisotope) is injected by lumbar puncture (spinal tap) into the cerebral spinal fluid to determine if there is abnormal CSF flow within the brain and spinal canal which can be altered by hydrocephalus, Arnold–Chiari malformation ...
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 ]
Successful procedures expand the area around the cerebellum and spinal cord, improving the flow of cerebrospinal fluid and thereby reducing the syrinx. [ 34 ] It is also important to understand the role of birth defects in the development of hindbrain malformations that can lead to syringomyelia, as syringomyelia is a feature of intrauterine ...
Decompressive craniectomy (crani-+ -ectomy) is a neurosurgical procedure in which part of the skull is removed to allow a swelling or herniating brain room to expand without being squeezed. It is performed on victims of traumatic brain injury, stroke, Chiari malformation, and other conditions associated with raised intracranial pressure. Use of ...
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 .
Arnold–Chiari malformation, or simply "Chiari malformation", a malformation of the brain; Budd–Chiari syndrome, a disease with typical symptoms of abdominal pain, ascites and hepatomegaly caused by occlusion of the hepatic veins; Chiari–Frommel syndrome, an older term for hyperprolactinaemia with extended postpartum galactorrhea and ...
[9] [10] This occurs ~2 1/2 months following injury, without associated neurological symptoms or pain, and typically resolves within 1 year. [ citation needed ] This sign is also sometimes seen as part of a " discontinuation syndrome " associated with certain psychotropic medications, such as selective serotonin reuptake inhibitors and ...
