Clinical question: Lumbar stenosis. Signs and symptoms : Low back pain and leg pain. Nonenhanced lumbar MRI:There is normal anatomical alignment the vertebral column. There is unremarkable signal intensity of vertebral column other than changes related to degenerative disease.Unremarkable lower most visualized thoracic spine and thoracic cord.T12 -- L1 is unremarkable.L1 -- L2 is unremarkable.L2 -- L3 is unremarkable with the exception of mild degenerative changes.L3 -- L4 demonstrate mild disk disease and loss of disk height, mild bilateral ligamentum flavum hypertrophy and minimal facet disease. No spinal stenosis or neural foraminal compromise.L4 -- L5 demonstrate mild disk disease and loss of disk height, moderate bilateral ligamentum flavum and facet hypertrophy changes as well as bilateral facet diffusion. No spinal stenosis or neural foraminal compromise.L5 -- S1 demonstrate advanced disk disease and significant loss of disk height, moderate bilateral facet and ligamentum flavum hypertrophy. No evidence of central spinal stenosis. There is however moderate to severe left and mild to moderate right neural foraminal compromise.Perispinal soft tissues demonstrate no abnormalities. Incidental note is made of a small single locule superficially located left renal cyst.
1.Degenerative changes of the lumber spine primarily at L4 -- L5 and at L5 -- S1 level as detailed.2.Neuroforaminal compromise at L5 -- S1 and unremarkable at other levels as detailed per level.3.No evidence of central spinal stenosis at any level.
