In most cases abnormalities are seen on a non-contrast scan, but the
visualization is much better and more information is obtained using contrast.

Did you get all these symptoms abruptly?

thank you so much for the response. Im going to say no, it started out with headpains but i think i later came to the conclusion they may have been caused by my tmj problem and i got a night guard and they went away. but now i seem to be having constant prosistent light headedness. nausea and hot flashes however are not presistent they come and go some days and some days no. do you think this sounds like anxiety?

Brain tumor symptoms usually come on abruptly.
These symptoms sound like anxiety ones.
Headache and dizziness may be caused by TMJ syndrome, and you may feel nauseous or vomit, due to problems with your TM joint, too.
Other problem that needs to be taken in consideration is overactive thyroid gland, or, hyperthyroidism.
I'll suggest you to make a blood test for your thyroid hormone status.

Are you constantly tensed and worried?
Have you noticed some weight loss despite your normal or even increased appetite?

i have had 2 CBC's i dont know if that checks your thyroid horomoes or not but i know it checked alot of stuff he showed me a bunch and everything was normal both times. Im wondering what makes you think its a thyroid involved problem. I will add that the nausea and hotflashes is not a presistent thing at all infact it comes on very seldomly now but i may get it for a little while every few days and its mostly if im worried about something. Im almost always tense i worry excessively about having a brain tumor or some undetected terminal illness and the mri only gave me slight relief from my worries. My biggest concern and basically my only symptom other then a stiff neck that i cracks alot is lightheadedness.. im lightheaded very often and it comes on worse when ..A:i think about it or B: im in a resturant or shopping mall or grocery store that kind of thing. Please write back, Thank you.

Being anxious and nervous is possible result of hyperthyroidism.

But, my opinion is that your problem is anxiety.
Even, TMJ (and headaches), can be caused by your anxiety (anxiety leads to bruxism (grinding of the teeth) and, tensed neck, face and scalp muscles).
Experiencing exaggerated worry and tension, often expecting the worst, even when there is no apparent reason for concern, is a characteristic for generalized anxiety disorder.
Feeling lightheaded when worrying and when being out at crowded places, seems like social phobia or social anxiety disorder.

Please, try to seek help for your anxiety!
Don't allow it to ruin your life!
It is very possible that the death of your close friend induced your anxiety.
Remember, that anxiety disorders are highly treatable with psychosocial therapies, medication, or both.

Best wishes!

thank you very much for all your replys mandyms. I believe that what you told me is true and that Anxiety is the rute problem. I took a test online for hypochonria and it came out "Extremly high" it said that beyond the shadow of a doubt i am a hypochonriac and it says that i most deffinatly have very high levels of anxiety. which would explain the lightheadedness and often dreamlike state im usualy in. I never said i had a close friend that died though, i havnt known anyone whos died so i dont know where that information came from?

Please, sorry for my mistake!
I have switch my thoughts to another user who was thinking that has brain tumor and whose friend recently died from the same disease.
Once again, sorry!

Anxiety may be caused by a mental condition, a physical condition, the effects of drugs or withdrawal, or from a combination of these.
Anemia, heart conditions can be related to anxiety issue.
Accumulation of stress from all life situations can lead to anxiety.
Help yourself with regular exercise (30 minutes of exercise three to five times a week can provide significant anxiety relief).
Try to learn some relaxation techniques, too.
