[Spondylodiscitis]

The authors present a clinical case of a female child, aged 23 months, previously healthy that 24 hours after falling down started to refuse walking and complained about back pain. She never had fever. She felt better with nonsteroidal antiinflammatory drugs, restarting the symptoms, two days after therapy suppression. At admission on hospital she presented inability to flex the lower back and loss of lumbar lordosis, being normal the remaining physical examination. There was a raise of erythrocyte sedimentation rate (ESR) and a radiological narrowing of the L1/L2 inter-vertebral disc space, a compatible image of spondylodiscitis in the MRI. Several diagnosis hipothesis have been considered, being infectious spondylodiscitis the most probable. We instituted tuberculosis therapeutic during one year and intravenous ceftriaxone for tree weeks followed by oral acetil cefuroxime (tree weeks). The spine has been immobilized with spine support. At four months disease and two months therapy, a Oerskovia xanthineolytica was isolated by intervertebral needle biopsy. A good clinical and radiological evolution has been observed. The authors stress the importance of MRI and intervertebral needle biopsy in the diagnosis of spondylodiscitis. It is also enhanced the use of MRI and ESR in the monitoring of response to the treatment.
