Spinal Epidural Lipoma on the Ventral Dura Side and Intervertebral Foramen Causing Lumbar Radiculopathy

Figure 2

Magnetic resonance imaging on T1-weighted (a), T2-weighted (b), and T2-fat suppression (c) reveal a mass (circles) of high-signal intensity at the L4 pedicle level in the left epidural space. The following were observed: a hyperintense anterior epidural mass (arrows) with strangulation of the dural sac at L4-5 levels (the first row), epidural mass (arrowheads) at L4 compressed asymmetrically on the left side of the cauda equina, and exiting left L4 nerve root on axial T1- and T2-weighted images (d, e) (the second row).
