Fig. 1

a Sagittal T2-weighted MR image of a 5-year-old Labrador retriever (dog 1) with degenerative lumbosacral stenosis and acute onset of discospondylitis. There is a hyperintense signal (exudate) visible in the intervertebral disc space. b Sagittal T2-weighted MR image of dog 1 after three months of treatment with oral antibiotics. The inflammatory exudate has disappeared. c Immediate postoperative radiograph of dog 1 after pedicle screw-rod fixation (PSRF) showing osteolysis of the L7 and S1 endplates. d Radiograph of dog 1 at four years after PSRF. Spondylosis deformans has formed ventral to the LS junction
