Clinical question: Spinal stenosis. Signs and Symptoms: lumbar canal stenosis. Nonenhanced lumbar MRI:There is advanced degenerative changes throughout lumbar spine. The signal pattern of the lumbar spine is compatible with DDD.T12-L1 demonstrate moderate disc disease and loss of disc height, mild facet and ligamentum flavum hypertrophy and without spinal stenosis or neural foraminal stenosis.L1-L2 demonstrate advanced dis disease and loss of disc height, mild right lateral recess compromise and unremarkable otherwise.L2-L3 demonstrate advanced dis disease and complete loss of dis height, mild grade 1 anterolisthesis, asymmetric right facet hypertrophy with moderate right neural foraminal and severe right lateral recess compromise.L3-L4 demonstrate advanced disc disease, complete loss of disc height, grade 1 anterolisthesis, asymmetric (R>L) facet degenerative changes with resultant moderate to severe left neural foraminal compromise and no central spinal stenosis. L4-L5 demonstrate moderate disc disease and loss of disc height, mild bilateral (L>R) facet and ligamentum flavum hypertrophy with resultant severe left neural foraminal and lateral recess compromise and no spinal stenosis. L5-S1 demonstrate mild disc disease and moderate left and mild right facet hypertrophic changes with resultant moderate left neural foraminal compromise. There is also a tiny synovial cyst arising from the left facet and projecting into the left lateral recess at this level. No spinal stenosis. There are multiple bilateral CSF signal intensity Tarlov cysts along the sacral neural foramen with bony remodeling.Lowermost visualized thoracic spine is unremarkable.
1.Advanced degenerative changes of the lumbar spine without spinal stenosis.2.Multi level neural foraminal compromise as detailed per level above.3.Multiple bilateral Tarlov cysts of the sacral spine and a tiny synovial cyst on the left at L5-S1 as mentioned.
