The role of laparoscopic biopsies in lumbar spondylodiscitis.

Infection of an intervertebral disk is a serious condition. Diagnosis often is elusive and difficult. It is imperative to obtain appropriate microbiological specimens before initiation of treatment. The authors describe a 51-year-old woman with lumbar spondylodiscitis that was because of infection after the placement of an epidural catheter for postoperative analgesia. A spinal magnetic resonance imaging confirmed the diagnosis, but computed tomography-guided fine needle biopsy did not provide adequate material for a microbiologic diagnosis. Laparoscopic biopsies of the involved disk provided good specimens and a diagnosis of Propionibacterium acnes infection. The authors believe that this minimally invasive procedure should be performed when computed tomography-guided fine needle biopsy does not provide a microbiologic diagnosis in spondylodiscitis.
