Herniation of cerebellar tonsils. [4] [38] [39] Tonsillar ectopia below the foramen magnum, with greater than 5 mm below as the most commonly cited cutoff value for abnormal position (although this is considered somewhat controversial). [27] [28] [40] [41] Syringomyelia of cervical or cervicothoracic spinal cord can be seen. Sometimes the ...
The cerebellar tonsil (Latin: tonsilla cerebelli) is a paired rounded lobule on the undersurface of each cerebellar hemisphere, continuous medially with the uvula of the cerebellar vermis and superiorly by the flocculonodular lobe. Synonyms include: tonsilla cerebelli, amygdala cerebelli, the latter of which is not to be confused with the ...
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.
Cerebellar tonsillar ectopia, aka Chiari malformation, a herniation of the brain through the foramen magnum, which may be congenital or caused by trauma. Ectopic cilia , a hair growing where it isn't supposed to be, commonly an eyelash on an abnormal spot on the eyelid, distichia
Cerebellar tonsillar ectopia (CTE) is a term used by radiologists to describe cerebellar tonsils that are "low lying" but that do not meet the radiographic criteria for definition as a Chiari malformation.
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 ...
Cerebellar tonsillar ectopia, or Chiari malformation, is a condition that was previously thought to be congenital but can be induced by trauma, particularly whiplash trauma. [14] Dural strain may be pulling the cerebellum inferiorly, or skull distortions may be pushing the brain inferiorly.
Cerebellar degeneration is a condition in which cerebellar cells, otherwise known as neurons, become damaged and progressively weaken in the cerebellum. [1] There are two types of cerebellar degeneration; paraneoplastic cerebellar degeneration , and alcoholic or nutritional cerebellar degeneration. [ 2 ]
