Figure 13

Examples of septic spondylodiscitis on MRI. (a–c) Sagittal view of the lumbar spine. There is a hyperintense signal of the subchondral endplates of L3-L4 on T2 and enhancement after gadolinium administration on T1. There are three consecutive interspinal cages in the interspinal space of L3-L5 surrounded by intense soft tissue enhancement. (d–f) Axial view at the intervertebral level of L3-L5 showing different aspects of discitis and paraspinal tissue enhancement (white arrows).
