Pyogenic spondylodiscitis without disc space collapse.

An unusual patient with pyogenic spondylodiscitis and preservation of the disc space anteriorly is reported. The diagnosis of pyogenic spondylodiscitis may be difficult when there is underlying spinal disease. We emphasize the need for early systematic imaging studies and intervention in such patients, including careful evaluation of vertebral endplates on plain films, early use of radionuclide studies, and prompt needle aspiration.
