    en.wikipedia.org/wiki/Chiari_malformation

    In neurology, the Chiari malformation (/ k i ˈ ɑː r i / kee-AR-ee; CM) is a structural defect in the cerebellum, characterized by a downward displacement of one or both cerebellar tonsils through the foramen magnum (the opening at the base of the skull).

  3. Cerebellar tonsil - Wikipedia

    en.wikipedia.org/wiki/Cerebellar_tonsil

    A Type I Chiari malformation is a congenital anomaly of the brain in which the cerebellar tonsils are elongated and pushed down through the opening of the base of the skull (see foramen magnum), blocking the flow of cerebrospinal fluid (CSF) as it exits through the medial and lateral apertures of the fourth ventricle. Also called cerebellar ...

    Such cerebellar tonsil herniation may occur in up to 70% of children with M-CM. [citation needed] The medical literature suggests that there is a risk of cardiac arrhythmias in early childhood. [8] [9] The cause for this is unknown. In addition, a variety of different congenital cardiac malformations have been reported in a small number of ...

    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 ]

    The treatment options vary since there are numerous causes of cervicocranial syndrome. General treatments include: Pressure release via realignment of the vertebrae; Pain medication: acetominophen, aspirin, or ibuprofen; Manipulation of neck by chiropractor: For example, vertigo symptoms can be relieved [25]

  8. Brain herniation - Wikipedia

    en.wikipedia.org/wiki/Brain_herniation

    There are many suspected causes of tonsillar herniation including: decreased or malformed posterior fossa (the lower, back part of the skull) not providing enough room for the cerebellum; hydrocephalus or abnormal CSF volume pushing the tonsils out; or dural tension pulling the brain caudally.

  9. Cerebrospinal fluid leak - Wikipedia

    en.wikipedia.org/wiki/Cerebrospinal_fluid_leak

    Arnold–Chiari malformation is a condition where the cerebellar tonsils have descended, and should be considered in differential diagnosis of sCSFLS. Several complications can occur as a result of sCSFLS including decreased cranial pressure, brain herniation, infection, blood pressure problems, transient paralysis, and coma.
