Three main categories for spinal infections:

  1. pyogenic
  2. tuberculous
  3. fungal (immunocompromised)

In pyogenic infection: early involvement of disc and more bone destruction.
In tuberculous infection: relative sparing of disc; usually subligamentous spread of infection with abscess formation; skipped vertebral lesions is possible due to subligamentous spread.

Note that metastasis sparing the disc.
