I'm not a doctor, but I'll take a crack at this since I have had this condition... It is a herniation (hole/deterioration) of the disk between the 4th and 5th lumbar that affects/irritates/exposes the nerve root that comes out of the spinal column at the L4 lumbar position.

What does paracentral disc herniation at the L5-S1 level causing mass effect upon the left S1 nerve root mean?

It means that the disc between L5-S1 has protruded out to one side (not centrally), and is affecting (most likely compressing) the S1 nerve root which is below the level of the herniation (the L5 nerve root has already exited the IVF). From this report I am assuming you are having some sensory or motor problems in your lower limbs?!


What does a small left paracentral disc herniation mean and how serious is it?

A disc herniation can be serious because it can cause severe pain and loss of feeling in your arms and legs. This kind of herniation basically means the rubbery cushion between the bones has moved out of its proper place.


What is nerve root effacement?
