Arachnoid Cyst-MRI

Arachnoid cysts represent benign cysts that occur in the cerebrospinal axis in relation to the arachnoid membrane and do not communicate with the ventricular system. They usually contain clear, colorless fluid that is most likely normal cerebrospinal fluid, but they rarely contain xanthochromic fluid. Most are developmental anomalies. On MRI, arachnoid cysts appear as well-defined nonenhancing intracranial masses that are isointense to CSF.

i found out today that i have an arachnoid cyst on the back of my brain.
it's been giving me migraines for over a year, and it's larger than a golfball.
we may have to operate, but normally that's not the case.
thank you for the (little) information you have provided here.
