1 Ιουλ 2019 · Cerebellar Tonsillar Ectopia is a mimic of Chiari I malformation. It is actually of the type of structural defects that are usually found in the cerebellum. The cerebellum is actually that part of the brain whose main function is to control the balance.
13 Δεκ 2023 · Tonsillar herniation, also known as tonsillar ectopia, is a condition where the cerebellar tonsils push through the foramen magnum, causing compression of the spinal cord. Learn about its causes, symptoms, diagnosis, and treatment options to better understand this neurological condition.
20 Οκτ 2023 · As a result, the lower part of the cerebellum known as the tonsils are pushed into the upper spinal canal. Chiari malformation type 2 is nearly always associated with a form of spina bifida called myelomeningocele.
Chiari Malformation Type I is typically diagnosed by greater than 5 mm of cerebellar tonsillar ectopy below the foramen magnum, typically due to the reduced size of the bony posterior fossa. Recent investigations have found CMI with a spacious posterior fossa, suggesting there are additional mechanisms for cerebellar ectopy

10 Νοε 2019 · The hypothesis is that tonsillar herniation is due to the direct mass effect, which causes displacement of posterior fossa structures through the foramen magnum because of diminished space for the normal cerebellar volume .
