We report a case of spondylodiscitis in two non-sequential segments of the lumbar spine that was unresponsive to antibiotic treatment instituted and guided by results of blood and urine cultures. A 70-year-old female was admitted to our hospital with complaints of adynamia, low fever, and severe lower back pain that caused difficulty in mobilizing the lower limbs. Spinal tomography and magnetic resonance imaging (MRI) of the lumbar spine suggested L2L3 and L5S1 spondylodiscitis. After an initial period of improvement, the patient's condition began to deteriorate again four weeks after initiating the antibiotic therapy. We then opted for surgical treatment through a full-endoscopic transforaminal route, with the aim of collecting intervertebral discs material and performing debridement. After the procedure, the patient experienced immediate relief from the pain and was able to stand and walk without assistance. Cultures from disc fragments showed different bacterial species than that found in the first examination. The endoscopic approach allowed less tissue damage, debridement of the disc, collection of multiple fragments, thereby facilitating the best antibiotic therapy, and shortening the duration of hospital stay.
