I had an MRI in October, (2 days before the insurance ran out). The doctor said not to worry about it, but to come back as soon as the new insurance kicks in. 
The reason for the scan was headaches, and a tremor in my left hand. The tremor was diagnosed as hereditary<sp?>, harmless but incurable.
I’ve been having some olfactory hallucinations. I’ve always had an incredible since of smell, but lately I smell things that I know aren’t really there.
Does anyone know what these spots could mean?
Brain Cloud.
Right down the middle.
How are you set for luggage?
Is your new insurance in effect yet? Do go back as soon as you can. Sending ya positive vibes, dear. 
You mean the doctor told you that you had spots on your brain, but didn’t explain to you what that meant? I would call the specialist’s office and ask that he call you. It’s unethical of him to withhold information relating to your health because your insurance ran out. Have a list of questions ready and don’t let him go until he’s answered your questions.
If he insists you come in, suck it up and pay the cost of an office visit. This is your health, for chrissake.
Ditto what PunditLisa said, in spades. Olfactory hallucinations can be lots of things, a few of them not good. Talk to the doctor.
I agree that you should go back as soon as possible. I’ll also point out that I’d imagine the doctor would have brought any serious problems to your attention. At least I hope so.
I second that opinion. (That’s why I posted pseudo-humor in the first place)
Stress can add to both real and imagined problems. So, if it really worries you, get thee to a doctor! Best wishes on you.
hillbilly queen, surely your doctor would have told you if it had been urgent. I am so hoping that is so.
As for those olfactory halluncinations – does it smell slightly like the Cherokee Boat Dock? If so, maybe it is just Old Hickory Lake again.
Here’s hoping!

I started having olfactory hallucinations a while back, posted about it, and was directed here:

Looks like it can be pretty serious. I checked with my doctor, and it turned out it was just allergies interfering with my sense of smell. She put me on Claritin, and I’m fine.
But I’d still get it checked out.
Strike another one for the Dope. I never heard of Olfactory hallucinations before I opened this thread.

Please go see a Doctor, or at least phone the present Dr and get clarified what was meant by “spots on the brain”.
Your health is a lot more important than money. If you don’t have the money, start phoning around for financial aid from the city, county or state or federal government.
My son had an MRI last year and it showed spots on the brain too. Specifically perioventricular malacia (sp). In his case they may or they may not have contributed to his LD’s and his ADD, depends on who you talk to and what their take on it is. So that’s one anecdotal piece of evidence that not all spots are a BFD.
But you need to know that. I’d ring and insist on knowing what they were and where they were. Did you get a copy of the MRI print out stuff? A copy of what the neurologist or whoever read the scan thought it was? I’d ask for those. We were instructed to keep the scan print out very safely because if he ever has a brain injury, they’ll need to see the original scan.
Good luck with getting more info and I hope your situation is as benign as my son’s. Well he’s got symptoms but they’re not anything we weren’t dealing with in the first place.
I forgot to mention, another form the hallucinations takes is smells replacing other smells. Not always, but occassionaly, such as… peanutbutter smelling like cat pee, coffee smelling like skunk…
I have sinus and allergy problems, so hopefully that’s all it is.
The new insurance starts this month.
Thanks everybody, for the well wishes.
