Spinal infection classification
Spine infections may be divided into the following major categories:
1. vertebral osteomyelitis (spondylitis):
a) pyogenic
b) nonpyogenic, granulomatous
● infection with Candida tropicalis
2. discitis: usually associated with vertebral osteomyelitis (spondylodiscitis)
a) Spontaneous spinal infection.
b) post-operative/post-procedure
4. spinal subdural empyema
5. meningitis
Intramedullary spinal cord abscess
MRI experience suggests that patients with infectious spondylitis will develop an associated epidural abscess if untreated, and that epidural empyema is unusual in the absence of vertebral osteomyelitis 1).
Thus, the discovery of one of these conditions should prompt a search for the other.
