Is a tonsillar herniation the same as the chiari malformation?
My mother was diagnosed with tonsillar herniation after having reported vertigo and having undergone some studies. Some websites report dire outcomes for tonsillar herniation patients (death and brain death) but much more optimistic outcomes for people with the chiari malformation. Until now the vertigo has been the only symptom and my mother only feels it when she is already lying down, trying to sleep, and she bends over in any way. Should we be concerned about an imminent death threat or is there a chance it could be a case of the chiari malformation. The herniation is supposed to have a growth of 7 mm, but the symptoms remain the same and it has not been possible to see a neurosurgeon to determine the seriousness of my mother’s case.
