Spondylodiscitis caused by Prevotella intermedia: A case report and literature review

Abstract

Background: Spondylodiscitis is commonly caused by Staphylococcus aureus. Anaerobic organisms are the causative agents in only 3–4% of cases. Diagnosis of anaerobic spondylodiscitis can be challenging due to their low virulence nature. Case description: We describe a rare case of spondylodiscitis caused by Prevotella intermedia managed with antibiotics and spinal instrumentation and highlight the challenges in diagnosis in such cases. Conclusion: Low virulent anaerobic spondylodiscitis can be difficult to diagnose. A high degree of suspicion is necessary and multiple attempts at pathogen identification, including possible open surgical biopsy may be required for diagnosis. A good prognosis is possible in appropriately managed cases. Keywords: Spondylodiscitis, Prevotella intermedia, Low virulent spinal infection, Instrumented fusion
