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 ...
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 ...
7) Tonsillar (downward cerebellar) Uncal herniation In uncal herniation, a common subtype of transtentorial herniation, the innermost part of the temporal lobe , the uncus , can be squeezed so much that it moves towards the tentorium and puts pressure on the brainstem , most notably the midbrain. [ 8 ]
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 shares many of the same symptoms as CSF leak, [58] but originates either congenitally or from trauma, including whiplash strain to the dura. [ 69 ] An alternate method of locating the site of a CSF leak is to use heavily T2-weighted MR myelography . [ 24 ]
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.
Midline shift is a shift of the brain past its center line. [1] The sign may be evident on neuroimaging such as CT scanning . [ 1 ] The sign is considered ominous because it is commonly associated with a distortion of the brain stem that can cause serious dysfunction evidenced by abnormal posturing and failure of the pupils to constrict in ...
Tonsillar branch may refer to: tonsillar branch of the facial artery; tonsillar branch of posterior inferior cerebellar artery; tonsillar branch of the glossopharyngeal nerve; tonsillar branch of the lesser palatine nerves
