case_images: He underwent an emergent lumbar magnetic resonance imaging which demonstrated mild-moderate multilevel degenerative spondylosis in the setting of congenital canal stenosis with significant lateral recess stenosis at L4-5 and a centrally herniated nucleus pulposus (HNP) at L5-S1 [Figure 1].

case_images: The patient was noted to have severe stenosis caudal to the S1 lamina intraoperatively, so this was also removed bilaterally and revealed a large sequestered herniated disc fragment [Figure 2] posterior to the S1-S2 disc space [Figure 3] causing severe sacral nerve compression.
