Figure 3 L4/5 infective spondylodiscitis in a 64-year-old
man. (a) Sagittal SE T1-W MR image shows an ill-defined hypointense lesion
involving most of the L5 vertebral body, with irregularity of the superior
endplate. (b) Sagittal fat-suppressed FSE T2-W MR image shows hyperintense
signal in the L5 vertebral body and the L4/5 disc, with anterior subligamentous
and posterior extradural extension. Appearances are typical of L5 vertebral
osteomyelitis with L4/5 discitis. Axial CT fluoroscopic images taken with
the patient lying prone show the Ostycut needle inserted into the (c) L4/5
disc and (d) L5 superior subchondral vertebral body via a left posterolateral
paravertebral approach.
