Left: Sagittal T1WI shows diffuse high signal within the intradural space. The cauda equina
appears to be displaced mostly anteriorly. Disk bulges are present at several levels.
Right: Axial T1WIs show the abnormal high signal within the intradural space with mass effect
on the nerve roots, which are displaced anteriorly and clumped together.
Left: Axial T2WIs show mildly heterogeneous hyperintensity within the thecal sac.
Right: Post contrast Sagittal and Axial T1WIs with fat saturation show no definite abnormal
enhancement. The high signal within the intradural space does not suppress.
