The myelin sheath that surrounds the nerve
Multiple sclerosis is a condition characterized by scattered patches of demyelination of nerve fibers in the brain and spinal cord. This demyelination disrupts the ability of nerve fibers to conduct electrical impulses, leading to various neurological symptoms.
A vasculitic process is something that was going on in your body that caused inflammation of vessels. Focal demyelination is a small area of loss of the "insulating" fatty layer that covers the nerves.

Demyelination is the loss of the protective covering (myelin sheath) around nerve fibers, which can lead to impaired nerve conduction. Denervation refers to the loss of nerve supply to a particular muscle or organ, which can result in muscle weakness or dysfunction. Both conditions can lead to a variety of neurological symptoms depending on the location and extent of the damage.
The nerves cells and brain cells have isolating cells around themselves that are called myelin. Demyelination means reduction of the number or size of those cells. Chronic means that the reduction lasts a long time or is permanent. Ischemic means that it is caused by lack of oxygen, which is most often due to bad blood supply. The condition will reduce the effectiveness of the conduction of nerve impulses or even cause nerve cells to get damaged too.
It means that there is a small amount of removal of the mylen sheath of the nerves in the white matter under the gray matter (which is the cortex of the brain). This part of the brain appears to be in semi-ovals and so the name.

An elongated T2 signal on an MRI scan typically indicates an abnormality in the tissue being examined. This could be due to specific pathologies like edema, inflammation, or demyelination. Further investigation would be needed to determine the underlying cause.
