Figure 3.

A 67-year-old man with a pyogenic infection (S aureus) for 2 months without any previous antibiotic treatment. A sagittal T1-weighted image (A) shows hypointensity on T12, L1 and L2. T2-weighted image (B) and FS MRIs (C) show the “inflammatory reaction line from the end plate” and the involved discs of T12, L1 and L2, which show hyperintense signals. The endplates were destroyed extensively. This infected disc and endplate comprise a typical “eye sign.” The infected disc can be thought of as an eyeball and the infected endplate can be regarded as an eyelid.
