migraines and weird mri findings?

 I get migraines and  seizures .   I also have a skull based mass the nuro /pain headache specialist  and a nuro specialist does not know what it is but thank god beilves its benign  but it has grown in the past three years. I last had it mri, on august 1 2009. ive had 20 plus mris and ct scans of my brain and skull  over the past 3 years just trying to track this and in all this time they say its not connected to the migraines but i have my doubts  but  I know longer see my old nuro pain  headache specialist I see a new nuro headache pain specialist. He looked at the Mri and wanted another mri and EEG im having trouble conving my mom theres any worth in having either ): the mass used to be 1.2 cm nows its 1.7 cm over the coarse of 3 years with it now being last i knew 1.7cm im not sure i want to know if it has grown . please tell me im not alone
