fatty growth in the brain ?

Hello! I went to a neurologist a while ago for headaches and dizziness. I had an mri done, and, when I saw the images, I thought I saw something weird on it. I know that brain MRI's aren't always going to be symmetrical, but there was a pretty significant bright spot, over a centimeter tall and at least half a centimeter wide (according to the scale provided on the disc). I asked the neurologist about it, and, at first, he just shrugged and said that the spot was "in an area that was not his area of study." During a follow up visit, he said that the radiologist said it was just a fat, and, again, shrugged it off. I'm sure I'm just being paranoid, but I didn't think that fat was supposed to grow in the brain, especially not on that scale. So, I was just wondering if a significant growth like that was normal or not?

Hello and Welcome

I appreciate your concern

Yes, a centimeter of fat as you mentioned is not normal in the brain. Most likely it was an artifact. You may obtain a second opinion radiology report on the lesion to confirm the finding.

Wishing you best of health

The human brain is nearly 60 percent fat. Essential fatty acids (EFAs) are required for maintenance of optimal health but they can not synthesized by the body and must be obtained from dietary sources. Clinical observation studies has related imbalance dietary intake of fatty acids to impaired brain performance and diseases. Most of the brain growth is completed by 5-6 years of age.
