Definition / general
- Inflammation of intervertebral disk tissue and adjacent vertebrae, which are normally resistant to infection due to avascularity
- Usually associated with back pain (since involves lumbar segments), ages 50+ years, male predominance
- Spondylodiskitis commonly involves lumbar (45%), thoracic (35%), and cervical (10 - 20%) spine; causes secondary epidural abscess most commonly in cervical spine, also thoracic and lumbar spine
- Increased frequency of diagnosis due to magnetic resonance imaging
- Most cases are due to pyogenic organisms (Staph, Strep); also Candida, Aspergillus, Cryptococcus, Mycobacterium tuberculosis; rarely Enterococcus
Diagnosis
- Culture usually positive (78%), special stains are usually negative
