Question Title: arachnoid cysts

I'm a 29 y/o male with symptoms that include pressure headaches, vision
disturbances, bilateral weakness in my arms, and others that have been
called "insignificant". I've had these symptoms for about a year now.
After many tests, the only abnormality is a 3.8x2.0cm arachnoid cyst in
the anterior aspect of the left temporal fossa, with associated mild
hypoplasia of the left temporal tip. A neurologist and the doctors making
the MRI reports all say that the cyst is congenital and is not related to
my symptoms. I find this very hard to beleive. I've been having a painless
pressure sensation in around the same area as the cyst. (This was before
I saw the films, so this is not psychosomatic or all in my head, so to
speak) I feel like I'm getting the run around from every doctor that I see.
Is it a coincidence that this forum and other neuro forums have many, many
posts from people that have neurological problems and arachnoid cysts to
which every response is, "arachnoid cysts are congenital and shouldn't be
related to your problems...blah blah blah etc...")

My questions are :

- Are there other tests that might be helpful? spec scan?

- My symptoms started after a viral infection or two, and a period of
some very intense prolonged stress. Could this have had an effect such as
a weakening of some outer brain covering and that in effect caused the cyst
to expand?

- If by some miracle I find a doctor that thinks that fenestration
or some other procedure to drain the cyst would be helpful, could THAT have
an unfavourable outcome since the cyst has been applying pressure to my
left temporal lobe for a about a year ?

- Could this possibly be something that IS causing my problems but there
is no treatment that would relieve my symptoms therefore doctors are
reluctant to inform me??

Any response would be appreciated.

Very Frustrated,
Roy
