Brucella spondylitis (BS) primarily shows chronic or acute-on-chronic inflammation microscopically, differing from spinal tuberculosis. Key features include foam cell reactions and granulation tissue, aiding diagnosis.
Area of Science:
- Pathology
- Microbiology
- Spinal Diseases
Background:
- Brucella spondylitis (BS) is an infection affecting the spine.
- Accurate pathological diagnosis is crucial for effective treatment.
Purpose of the Study:
- To investigate the microscopic pathological features of Brucella spondylitis.
- To provide pathological references for diagnosing BS.
Main Methods:
- Retrospective analysis of 70 BS patients.
- Histopathological examination using H&E staining.
- Analysis of granulation tissues, bones, discs, and sequestrums.
Main Results:
- Chronic or acute-on-chronic inflammation observed in most cases.
- Foam cell and histiocytic reactions were prominent.
- Granulation tissue hyperplasia was common, unlike in spinal tuberculosis.
Conclusions:
- Chronic inflammation is the hallmark of BS.
- Microscopic findings like foam cell reactions and granulation tissue are key for differentiating BS from spinal tuberculosis.
