Lower back pain, left leg occasionally gives out Five lumbar type vertebral bodies are presumed to be present. Vertebral body heights are within normal limits. Alignment is within normal limits. Bone marrow signal is benign. The conus medullaris is normal in position.There is congenital narrowing of the lumbar spine with superimposed prominence of the epidural fat consistent with epidural lipomatosis. Individual levels as below:L1-L2: No significant disc disease. No spinal canal or neural foraminal stenosis.L2-L3: No significant disc disease. There is mild mass effect on the thecal sac related to epidural lipomatosis. No significant neural foraminal stenosis.L3-L4: No significant disc disease. There is moderate degree of mass effect on the thecal sac related to epidural lipomatosis. Mild bilateral neural foraminal stenosis. Moderate bilateral facet arthropathy.L4-L5: No significant disc disease. There is moderate mass effect on the thecal sac related to epidural lipomatosis. No significant neural foraminal stenosis. Mild facet arthropathy.L5-S1: No significant disc disease. There is moderate degree of mass effect on the thecal sac related to epidural lipomatosis. No significant neural foraminal stenosis. Mild facet arthropathy.Paraspinous soft tissues demonstrate prominence of the subcutaneous fat but are otherwise within normal limits.
Diffuse epidural lipomatosis involving the lumbar spinal canal associated with at least moderate degree of spinal canal stenosis at the L3-L4, L4-L5, and L5-S1 levels. No significant disc disease or high-grade neural foraminal stenosis at any level.Multilevel facet arthropathy, relatively worse at the L3-L4 level, which may be contributing to patient's low back pain.
