The clinical course of pyogenic spondylodiscitis varies based on its etiology. To the best of our knowledge, there have been only 7 cases of spondylodiscitis caused by Klebsiella oxytoca. This bacterium typically affects patients with underlying comorbidities or develops as a secondary infection. This case illustrates a rare instance of lumbar spondylodiscitis caused by Klebsiella oxytoca. A direct biopsy via endoscopic surgery may be beneficial when multiple bacterial culture investigations yielded negative results. It is important to recognize that identifying the causative pathogen is crucial when initiating antibiotic therapy for spondylodiscitis.
