(a) Sagittal and (b) axial views of a lumbar magnetic resonance imaging (MRI) revealed multilevel lumbar spondylosis and evidence of clumping (arrows) and posterior displacement of nerve roots of the cauda equina within the thecal sac suggesting arachnoiditis

A lumbar magnetic resonance imaging (MRI) with and without gadolinium contrast revealed multilevel lumbar spondylosis and clumping/posterior displacement of nerve roots of the cauda equina from L2-3 through L5-S1 compatible with arachnoiditis due to the prior surgery [Figure 1a and b].

(a) Sagittal and (b) axial views of a thoracic magnetic resonance imaging (MRI) scan revealed evidence of abnormal T2 signal in the conus over a 4.3 cm segment (arrows). (c) Sagittal view of a thoracic MRI scan performed 2 months later showed that the enhancement within the conus and the cord swelling had decreased, however, there were mild residual T2 signal changes (arrow)
