Summary

Spondylodiskitis, an infection of the spine, shows vascularization and necrosis on histopathology. Cultures are crucial for identifying causative bacteria in this increasingly diagnosed condition.

Area of Science:

  • Spinal imaging and pathology
  • Infectious disease diagnostics

Background:

  • Spondylodiskitis diagnosis is rising due to advanced MRI.
  • Limited data exists on its bacteriology and histopathology.

Purpose of the Study:

  • To investigate the bacteriology and histomorphologic features of spondylodiskitis.
  • To correlate radiologic findings with pathologic changes.

Main Methods:

  • Analyzed 27 biopsy/debridement specimens from 20 spondylodiskitis patients.
  • Performed microbial cultures and histopathologic examination (H&E, special stains).

Main Results:

  • Disk tissue showed vascularization, myxoid degeneration, and necrosis.
  • Chronic osteomyelitis was universal; 21/27 cultures were positive (mostly pyogenic bacteria).

  • Histologic stains identified organisms in only 4 cases, correlating with florid acute inflammation.
  • Conclusions:

    • Histopathology reveals vascular proliferation, degeneration, necrosis, and adjacent osteomyelitis in spondylodiskitis.
    • Positive cultures are highly sensitive for identifying the etiologic organism.
    • Biopsy tissue submission for culture is essential for accurate diagnosis.
