Fatty Sheathing (MRI)

I had vertigo (for the first time on December 25/26th) which finally ended in with a migraine. I have been having migraines since 2008. They have been coming more often within the last year. At this point I have them about every 4 to 6 weeks. My dr. gave me Treximet...which, for me, has been a miracle! However, I had an MRI last week and was told that they found "fatty sheathing on the left frontal portion of my brain". What the heck is that? I've been having "brain fog" and many occasions that I have forgotten what I was doing or saying...more than normal.

Any thoughts?

Re: Fatty Sheathing (MRI)

Welcome to the board.

"fatty sheathing on the left frontal portion of my brain". What the heck is that?

This is referring to some of the "anatomy" of neural structure.

There is an insulating layer that forms around the nerve, including those in the brain. It is made up of protein and fatty substances...and is referred to as "myelin" or the "myelin sheath." The purpose of it is to allow signals to transmit quickly along the nerve cells. When the myelin becomes damaged, it can lead to disease.

This fatty sheath insulates the axon from electrical activity.

We would need to see this in context to the rest of the radiology report to know exactly what the radiologist was pointing out.

This is the only way I know that the term "fatty sheath" is used...but I am not a doctor, so perhaps there are other meanings.

When do you see your doctor to find out the results?
