Spondylodiscitis complicated by an epidural abscess and meningitis caused by Bacteroides fragilis.

Bacteroides fragilis is a rare causative agent of spondylodiscitis. The pathophysiology of B. fragilis in spondylodiscitis remains largely unclear because of its rare occurrence. We herein report a case of spondylodiscitis complicated by an epidural abscess and meningitis; B. fragilis was detected in the blood of the patient. Moreover, the patient had a splenic abscess that was confirmed on magnetic resonance imaging. The patient completely recovered with antimicrobial therapy alone.
