Fatal neck pain in a patient on maintenance hemodialysis.

Infectious spondylodiscitis (IS) is defined as the pathogenic invasion of the vertebrae and intervertebral disks. It is a serious condition that can lead to many complications such as chronic pain, permanent neurological deficits, and even death. Vertebral surgical procedures, invasive urinary tract manipulations, and central line-associated bloodstream infection are the primary methods by which microorganisms reach the vertebrae and intervertebral disks.
