Which combination is classic for spinal epidural abscess requiring emergent evaluation in the emergency department?

• A. Fever, back pain, and recent dental procedure
• B. Fever, IV drug use, severe back pain
• C. Chest pain and shortness of breath
• D. Gradual onset knee pain

Answer: (B)

Spinal epidural abscess is most strongly suggested when fever and back pain occur in someone with a major risk factor like IV drug use. The combination signals a likely infectious process that can spread to the epidural space and rapidly progress to spinal cord compression and neurologic injury, so urgent evaluation is needed. The typical reason IV drug use raises concern is hematogenous spread of bacteria, especially Staphylococcus aureus, to the spinal canal. Because time matters, this presentation warrants emergent MRI of the spine to confirm the diagnosis and guide urgent treatment with antibiotics and possibly surgical decompression. The other scenarios don’t pair fever and back pain with a high-risk factor for hematogenous spread, making spinal epidural abscess unlikely in those contexts.
