Bifocal cervical spondylodiscitis due to Citrobacter diversus.

Spondylodiscitis due to Citrobacter diversus is rare. An unusual case of bifocal cervical spondylodiscitis following transurethral prostatectomy is reported. C. diversus was detected by urinary cultures and locally by intervertebral disc puncture. Satisfactory recovery occurred after treatment with imipenem and amikacin, and then imipenem alone. Citrobacter infections are still rare in adults but are increasing in immunocompromised patients and sometimes occur in healthy subjects following surgery.
