They may develop nearly anywhere in the body and usually require complete excision for eradication or they are likely to recur. Fluid filled sacs that are not cellular lined ...Read more

I have a chiari 1 malformation, and an arachnoid cyst, how do I know if I am a candidate for surgery?

See a neurosurgeon: Depending on the location of the arachnoid cyst and the degree of cerebellar tonsilar ectopia from your chiari, you may well be a surgical candidate. Posterior fossa arachnoid cysts are a common cause of secondary chiari malformations (if the cyst is large enough to create increased pressure, it can push the bottom of the cerebellum through the foramen magnum, causing the chiari). See neurosurgeo. ...Read more

I have an arachnoid cyst and a chiari 1 malformation. I know it depends on the person but how likely is it that I will need surgery?
