A member asked:
Mri: "there is mild-mod right foraminal narrowing on the right side at l4-l5. the dural sac and contents appear unremarkable" what does this mean?
A doctor has provided 1 answer
The foramen is: the opening through which a nerve root exits the spinal canal. When it is narrowed, usually by degenerative arthritis and/or a disc herniation, it can pinch or squeeze the nerve root going through it, possibly causing symptoms. In your case it would be the right L4 nerve root. The dural sac is the membrane surrounding the spinal cord.
