1.5y MC Boxer with hunched back and stiff pelvic limb gait but minimal neurologic deficits. The radiographic image shows vertebral
endplate osteolysis, surrounding bone sclerosis, and mild disk space narrowing of the L2–3 intervertebral disk space (a: arrowhead). On
MR images, the L2–3 disk space is ill defined with heterogeneous T2 and T1 hyperintensity (b,c,e,f: arrowhead). There is also mild T2
hyperintensity and T1 hypointensity of adjacent bone in the vertebral bodies (b,c: arrows). The affected intervertebral disk (d,g: large
arrowhead), adjacent bone (d: arrows), and surrounding soft tissues (g: small arrowhead) intensely contrast enhance. Fine‐needle
aspiration cytology of the lesion revealed suppurative inflammation, and Staphylococcus intermedius was cultured.
