case_images: The axial T2-weighted MR scan obtained just above the L3-L4 level documented the foraminal and far lateral extent of the L3-L4 disc herniation (arrow), which migrated superiorly. Note the obliteration of the left-sided cephalad L3 root

case_images: The FOR/FLD disc herniation extended all the way to the L2-L3 level (e.g. markedly compressing the axilla of the L3 root) [Figures 1-4].
case_images: The parasagittal T2 MR scan documented the massive left-sided foraminal, far lateral, disc fragment (arrow) originating at the L3-L4 level with substantial superior migration opposite the L3 pedicle

case_images: The FOR/FLD disc herniation extended all the way to the L2-L3 level (e.g. markedly compressing the axilla of the L3 root) [Figures 1-4].
case_images: The soft tissue window axial CT obtained just above the L3-L4 disc level similarly documented the foraminal and far lateral extent of the L3-L4 disc herniation (arrow). Note the absence of significant ossification/spur formation

case_images: The FOR/FLD disc herniation extended all the way to the L2-L3 level (e.g. markedly compressing the axilla of the L3 root) [Figures 1-4].
case_images: The left-sided parasagittal CT scan, compared with the MR, more poorly documented the massive foraminal, far lateral, disc fragment (arrow) originating at the L3-L4 level with substantial superior migration

case_images: The FOR/FLD disc herniation extended all the way to the L2-L3 level (e.g. markedly compressing the axilla of the L3 root) [Figures 1-4].
case_images: Penfield elevator in the L3-L4 disc space itself to confirm the correct localization. Note the Penfield/dental tool at the cephalad L2 and caudal L5 extent of the lumbar decompression

case_images: Penfield elevator correctly located within the L3-L4 disc space (e.g. this is used to avoid wrong-level diskectomy) [Figure 5]. Postoperatively, the patient was neurologically intact, and never demonstrated instability.
