What does "paravertebral" mean ? (explain)?

Answers:
It means "around" the vertebrae. For example the paravertebral muscles are the two long muscle groups that run down your back on either side of the midline. A paravertebral tumor is one that lies around or adjacent to the spinal column.

it means on each sides of the vertebral column ie, the backbone.. like the sympathetic chain is present one on each side of the vertebral column!

I must agree. Para is from the latin for beside or on the side of, and vertebral means of or relating to the spine.It probably refers to the rest of the spinal column and any possible damage therin.
