1 A 63-year-old man with left L5 radiculopathy on the electromyographic study, who underwent an operation 12 months ago. A 63-year-old man with left L5 radiculopathy on the electromyographic study, who underwent an operation 12 months ago. A, Axial T1-weighted MR image before contrast injection shows left central intermediate signal intensity epidural lesion (arrow). B, Axial T1-weighted MR image after contrast injection. Enhancement is noted in the left epidural and intradural L5 nerve root (arrows). Nonenhanced disk protrusion is seen (arrowhead). Nonenhanced sagittal T1-weighted (C) and enhanced sagittal T1-fat suppressed (D) MR images show mildly enhanced intradural nerve root and bright enhancement of epidural nerve root (arrows). Y.S.
