This phrase refers to a slight change in the shape of the protective covering (the thecal sac) and the cord on the right side of the body. This change is caused by a small, central disc protrusion, which is when a disc in the spine bulges out a bit. This bulging disc is not causing any narrowing of the spinal canal or the openings where the nerves exit the spine.
