Clinical Scorecard: A Spinal TB Mimic: Salmonella Dublin

At a Glance

Key Highlights

• Initial suspicion of spinal tuberculosis based on clinical and imaging findings
• Negative initial microbiologic evaluations including tuberculosis screening
• Surgical debridement led to definitive diagnosis of Salmonella Dublin
• Targeted antimicrobial therapy resulted in prompt clinical improvement
• Patient resumed normal activities after treatment completion

Guideline-Based Recommendations

Diagnosis

• Utilize culture and mNGS for definitive pathogen identification
• Consider surgical tissue sampling in cases of diagnostic uncertainty

Management

• Discontinue ineffective anti-tuberculosis therapy upon identification of Salmonella
• Initiate targeted treatment based on antimicrobial susceptibility testing

Monitoring & Follow-up

• Regular follow-up imaging to assess treatment response
• Monitor inflammatory markers and clinical symptoms

Risks

• Misdiagnosis of spinal infections as tuberculosis leading to inappropriate treatment
• Potential for disease progression if correct diagnosis is delayed

Patient & Prescribing Data

14-year-old boy with systemic symptoms and imaging suggestive of spinal infection

Prompt initiation of targeted therapy after definitive diagnosis led to recovery

Clinical Best Practices

• Maintain a high index of suspicion for non-tuberculous infections in endemic areas
• Employ multidisciplinary approaches for complex cases
• Ensure thorough diagnostic evaluation before initiating empirical treatments
