Cervical spondylodiscitis mimicking Pott's disease: a case report.

INTRODUCTION

The leading cause of pyogenic vertebral osteomyelitis is Staphylococcus aureus, and its incidence is rising, particularly in the elderly. We report an unusual case of cervical spondylodiscitis and epidural abscess mimicking Pott's disease.

CASE REPORT: A 67-year-old man was admitted to our institution with a 15-day history of neck pain radiating to the head, shoulders and left arm that was associated with weakness and paresthesia. Laboratory tests showed a mild leucocytosis and high levels of inflammatory markers. The MRI showed contrast enhancement of C6-C7 with an abscess infiltration extending to the intervertebral disc, the anterior epidural space, and the medullary cord. The patient had a medical history of a positive Mantoux tuberculin skin test 25 years prior, and the interferon-gamma release assay (IGRA) was positive for the identification of latent tuberculosis infection. All other examinations for diagnosis of spinal tuberculosis were inconclusive. Intravenous antibiotic therapy was initiated with teicoplanin 800 mg and levofloxacin 750 mg daily with a fast recovery of symptoms.

CONCLUSIONS

Cervical spondylodiscitis can be an unusual cause of severe neck pain with a challenging differential diagnosis. Conservative treatment should always be considered for patients without neurological symptoms as long as close follow-up evaluations are performed.
