3 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.
