Could a lightened area in a brain MRI be an infection or a tumor?

Hello doctor,

I had an magnetic resonance imaging (MRI) performed on my brain due to my visual perception being off and not seeing and understanding my location correctly while driving.I did hit someone and almost got into a larger accident. The right side of my head feels like there is a cyst or something there. My skull on the upper back right side would feel sore, bruised when touching it. It felt like a cyst, or something was inside the brain beyond the skull. After the MRI, it felt like a large bubble has got released from that area bursting into my skull. After the bubble burst, about an hour after the MRI, the bruising feeling in my skull started disappearing. There is a feeling like something is in my head in the upper back right side radiating up and down into my neck. On the right side of my neck, sometimes I feel a pinch or swelling but mostly feels like a lymph node is swollen. The MRI showed that I have a meningioma and localized frontal atrophy. The atrophy looks horrendous to me, and I found a lightened area where I have pain but it is not on the right but left side. My questions are: 1. Can you tell me whether a lightened area on an MRI could be an infection and not a tumor? As far as the atrophy is concerned, I have felt like my brain cannot create its energy for about 1 to 2 years. I was drinking a lot of sugar to provide energy but then started using supplements like acetyl carnitine which changes fat to fuel. I was under a lot of stress for several years and also was using a lot of anticholinergics like allergy medicine and antidepressants. 2. I read that the brain will cannibalize itself for Choline. I take Choline now, but do you think my brain shrunk due to stress, not enough Choline, low blood pressure (not enough nutrients)? Would acetyl carnitine which helps utilize fat for fuel cannibalize my brain for fuel if I do not have enough glucose or ketones? Currently, I am on Lexapro 20 mg, Wellbutrin 75 mg and Spironolactone 25 mg.

Thank you doctor,

I am trying to consult a neurologist, but my doctor wrote me an order and the neurologist wants it faxed. I have been going back and forth to the offices. The magnetic resonance imaging (MRI) findings: No diffusion restriction in the brain. Along the right posterior aspect of the falx abutting the posterior aspect of the superior sagittal sinus, there is a homogeneously enhancing mass measuring 0.55 x 0.43 x 0.55 inch. It shows hypointense signal on T2-weighted imaging. No adjacent vasogenic edema within the brain. No other pathologic enhancement on postcontrast images. No midline shift. No ventricular dilatation. Localized atrophy along the frontal regions. No abnormal hyperintense T2 or FLAIR signal within the brain. Flow voids are intact. No abnormal susceptibility on the gradient echo sequence. The impression: Small right parafalcine meningioma abutting the superior sagittal sinus at the posterior aspect and measuring 0.55 x 0.43 x 0.55 inch. No acute infarct.
