Preoperative sagittal T1-WI with contrast enhancement (a), sagittal T2-WI (b), and axial T2-WI (c) MRI showed a T12/L5 anterior epidural hypointensity with ring enhancement on T1-WI sequences after gadolinium administration, with a maximum diameter of 1.2 cm at L2-L3 causing severe cauda equina compression.

T12 to L5. The lumbosacral MRI documented a T12/L5 anterior epidural hypointense lesion with ring enhancement; the maximum AP diameter was 1.2 cm at the L2-L3 where it caused severe cauda equina compression [Figure 1].
Postoperative sagittal T1-WI with gadolinium administration (a) and sagittal T2-WI (b) MRI documented an adequate decompression with complete abscess drainage.
