Management of Spondylodiscitis

Diagnostic Approach

  • MRI with and without contrast is the primary diagnostic modality for spinal infections, with 96% sensitivity, 94% specificity, and 92% accuracy 2, 3
  • [18F]FDG PET/CT could be the preferred modality for detection of spondylodiscitis within 14 days of symptom onset 1, 4
  • CT-guided biopsy is recommended when blood cultures are negative to establish microbiological diagnosis 3
  • Monitor inflammatory markers (CRP and ESR) to assess disease activity and treatment response 1

Antimicrobial Therapy

  • No relevant cited facts available

Surgical Management

  • Surgical intervention is indicated in scenarios such as neurological deficits with spinal cord compression 3

Monitoring and Follow-up

  • Regular monitoring of inflammatory markers (CRP and ESR) is essential to assess treatment response 1
  • Follow-up MRI is recommended to evaluate treatment response, though imaging findings may normalize more slowly than clinical and laboratory parameters 3
  • CT is useful for follow-up in patients with spinal instrumentation 2, 3
  • Approximately 10% of cases may have non-contiguous multilevel infections, which should be considered during follow-up 1, 4

Special Considerations

  • For patients with spinal hardware, [18F]FDG PET/CT is recommended, preferably performed 3-4 months after surgery 1, 5
