Hi all!

My arachnoid cyst was found 10yrs ago (temporal left) and untill today i cant find a decent answer is this cyst large or medium or relatively small.
On MRI report the cyst is 4.5cm x 2.5cm x 2.3cm
Ive had headaches, but vertigo and fuzzy - blurry head are present on almost daily basis.

I would like to know the possible treatments for this arachnoid cyst and also is the size of this cyst to concern in future (it didnt expanded in last 3 yrs)?

many thanks
