This is the only type also known as an "Arnold–Chiari" malformation. As opposed to the less-pronounced tonsillar herniation seen with Chiari I, there is a larger cerebellar vermian displacement. Low-lying torcular herophili (confluence of sinuses), tectal beaking, and hydrocephalus with consequent clival hypoplasia are classic anatomic ...
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 ...
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.
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.
Upper airway constrictions (e.g., deviated nasal septum) or obstructions (e.g., enlarged tonsils) or infections (e.g., rhinitis) General hypotonia or low body tone; Low-lying resting posture of the tongue; Imbalance in dental growth; Inadequate development of facial and cranial bones; Inappropriate development of muscles in the head and neck areas
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 ...
The phrase “low-key” expresses a lackluster feeling that’s analogous to “sort of." Depending on where you look, low-key can be spelled as one word, two words or as a hyphenated phrase.
