I suffer from migraines and I also developed a tumor in the right side
of my neck that has grown on my nerves so it cannot be removed without
great risk to my nerve recently I have started getting migraines on my
left side on a daily basis I was prescribed propranoral, maxalt,
hydromorphone but they don't seem to work and I also have been
blacking out when getting these pains in my head my right arm also
becomes numb.  My doctor sent me for a mri and I got the results
before the doctor did and I don't know how to interpret the results
and that is where I need your help the report reads as follows:
There has been no change in the scattered tiny foci of increased T2
and FLAIR signal in the frontal and parietal lobes bilaterally. There
is membrane thickening of the right maxillary sinus.
The left transverse sinus is hypoplastic.  The left sigmoid sunus is
not visualized.  There are collateral vessels in this same region on
the left.  There is an absence of a tiny portion of the right
transverse sinus.  The jugular veins are not well visualized on the
study.
The impression reads:
Unchanged bilateral foci of increased T2 and FLAIR signal in the
frontal and parietal lobes and this is a nonspecific finding. 
Unchanged hypoplastic left transverse sinus absent left sigmoid sinus.
 Unchanged collateral vessels on the left consistent with congenital
abnormality

As a nurse who has worked in neurosurgery - 
You need to discuss the MRI results with your doctor.  He or she will
know much more about your medical history (i.e. the congenital
abnormality mentioned) and should be able to interpret and explain the
results to you.  The information you posted would have been written by
a radiologist (a doctor specializing in x-rays, MRI, etc.) and is
intended for medical personnel familiar with the anatomy and
physiology of the area being studied.  Is your doctor a
neurologist/neurosurgeon, or a GP?  If you are only seeing a GP at the
moment, it may be a good idea to ask for a referral to a neurologist.
Again, it is crucial that you discuss these findings with your doctor
so that you can work together to resolve this problem.
Best of luck.

Do what kateri has suggested.  That is good advice.

I hope all goes well !

Good luck.

mri - fairly typical report which in layman's terms looks like no
tumor, some sinus inflammation (very common), and some unusual
findings which are most likely very stable and noncontributory.

headaches - best to see a neurologist

tumor in neck -  immediately to ear nose and throat, or plastic surgeon,
