Correct answer: Spinal TB. I should probably have given you more information so you’d have a fair chance at getting the answer right, I’ll do that next time. Anyway, in a matter of weeks or months, an abcess has formed that’s compressing the spinal cord. Possible findings include back pain, mild fever, leukocytosis and an elevated ESR. Treatment is the standard TB-medication (8 weeks on rifampicin, isoniazide, pyrazinamide and ethambutol, then 16 weeks on just rifampicin and isoniazide).
