Clinical question: Bilateral lower extremity weakness and numbness. Signs and symptoms: Bilateral lower extremity weakness and numbness. Nonenhanced lumbar MRI:There is normal anatomical alignment of vertebral column.Unremarkable lower most visualized thoracic spine and thoracic cord from T11 inferiorly.T12-L1 is unremarkable.L1-L2 is unremarkable.L2-L3 is unremarkable.L3-L4 demonstrate mild disc desiccation, moderate bilateral ligamentum flavum hypertrophy, mild bilateral facet disease and bilateral facet effusion. Mild bilateral neural foraminal and central spinal stenosis is noted.L4-L5 demonstrate mild disc disease, mild bilateral ligamentum flavum hypertrophy and mild facet disease with suspected bilateral facet effusion. No evidence of central spinal stenosis however mild right neural foraminal compromise is noted.L5-S1 demonstrate minimal degenerative changes without spinal stenosis or neural foraminal compromise.Partially visualized kidneys demonstrate small cysts on the right.
1.Mild degenerative changes of lumbar spine as detailed.2.Mild central spinal stenosis only at L3-L4 is noted.3.Mild neural foraminal compromise as detailed per level.
