8 Year Old Son...Please help

My son has had migraine headaches, as I did when I was a child for over a year with great frequency (2-3 times per week). We have been trhough hell with scheduling an MRI, 1st Pediatric Neurologist said no, just CAT and EKG, so we moved on after the EKG nurse told me we should have more kids "just in case" and in front of my son.

He is fully functional, nothing other than the headaches, top grades etc. Here is the result from his MRI and we cannot speak to his new Neurologist until April 8th. We were told by the assistant he was fine, nothing on MRI, then she called back the next day crying and apologizing that she looked at the wrong records. Anyway, here it is - Please help with some thoughts:
*******************************************beginning of report*************************

Sedation (although he looked like was still he apparently wasn't, they sedated and machine broke down in the middle so MRI took ~ 2 hrs) : Robinul .12MG IV -Versed 5.2 mg IV Nembutal 200 mg IV

Technique: Muliplanar sequences of the brain were done with and without contrast.

Findings: No prior studies are available for comparison. Multiple focal areas of increased T2-weighted signal are seen throughout both cerebral hemisperes being more prominent in the right frontal lobe white matter and also in trh frontoparietal subcortical white matter superiorly. Largest lesion measures 1.2cm and is seen the left perirolandic subcortical white matter. No pathological enhancement is seen. No lesion is seen in the basal ganglia or posterior fossa. Ventricles are normal in size

Mild bilateral maxillary, ethmoid and sphenoid mucosal thickening is seen.

Conclusion: Multiple bilateral cerebral hemisphere white matter lesions as noted. Differential diagnosis includes areas of demyelination versus gliosis. Clinical and labaratory correlation is recommended. Follow up MRI is recommended.

Mild pansinus mucosal thickening
***************************************************the end****************************************************

Finally as a note to Neurologist #1 CAT scan and EKG - He stated that my son has a pineal cyst ~ 1.2CM that was not picked up on MRI but note the lesion size on largest lesion is same.

Due to Neuro # 2 vacation, we have to wait until April 8 to learn what this means. Please advise now as my wife and I are obviously worried plus searching Google only makes it worse.

So, can I assume this MRI report is beyond help on this site for interpretation? As a newcomer I thought there were people in the know that would offer some insight without fear of liability/ Am i wrong on this?

I hope you get an answer, I have a 9 year old with a large (in excess of 10cm) cyst on the brain.  

Please keep us updated, I'll be watching!
