Doctor insights on:
Are you: referring to a spine MRI? The lateral recesses are regions along the sides of the spinal canal through which nerve roots run after exiting the dural sac. Effacement means that the space is compromised, usually by a disc or degenerative change, and the nerve root may be compressed. ...Read more
Could near complete effacement of the thecal sac cause neuro problems with eyes, dizziness and nausea. I also have a gross swelling of right hand.?
Probably unrelated: The thecal sac is what surrounds the spinal cord and contains spinal fluid. Effacement just means that there is no fluid in the space around the spinal cord. This can be from pressure inside the cord, outside the cord, or a non-specific normal variant. You need to discuss this with your doctor and get a thorough neurological evaluation. ...Read more
MRI shows multilevel cervical spondylosis throughout cervical spine most severe C4-5 & C5-6 resulting in complete effacement of CSF & moderate spinal canal stenosis; no abnormal cord signal. What does this mean & how dangerous is it?
It means DDD disease: in Ur C-spine which is extending posterioly 2 push on the dura, the sack that encompasses the cord in fluid, far enough 2 indent this sack so there is no fluid visible between arthritic process & the cord. Cord signal is normal so the cord is not effected. The "stenosis" means the canal the cord passes through is narrowed moderately. It's rated as none, mild,moderate & severe ...Read more
Being pressed on: This means the nerve root is being pressed on as it exits the spine. For example, it could be pressed on by a disc or by changes in the bones or ligaments related to arthritis. However, just because a scan may show the nerve being pressed on doesn't mean it is causing symptoms. This has to be decided after speaking with and examining the patient. ...Read more
Can't say: specifically without more information or viewing the images, but it is likely referring to mass effect due to the downward displacement of the cerebellar tonsils through the foramen magnum seen in Chiari 1. Normally csf surrounds the cervical cord, the cerebellar tonsils in Chiari occupy this space and "efface" the csf space., so this can create an obstruction to normal csf flow or press on cord. ...Read more
