Three magnetic resonance images of vertebral osteomyelitis due to methicillin-resistant Staphylococcus aureus

(A) T2-weighted axial image shows collections in the psoas muscles bilaterally (arrows) representing abscesses.
(B) T2-weighted sagittal image demonstrates increased signal in the L2/3 and L3/4 intervertebral disc spaces (arrows).
(C) Post-contrast sagittal fat saturated T1-weighted image shows enhancement in the intervertebral disc spaces (arrows) and adjacent L2 to L4 vertebral bodies (arrowheads).
