Clinical question: Follow-up lumbar stenosis. Signs and symptoms: Low back and lower extremity pain. Nonenhanced lumbar MRI:At T11-12 through L2-L3 levels mild to moderate degenerative changes without central spinal or neural foraminal compromise is noted. There is no significant change since prior exam.L3-L4 demonstrate progression of degenerative changes with resultant moderate to severe central spinal stenosis. There is worsening diffuse broad based bulging disc (L>R) contributing to spinal stenosis. No significant neural foraminal stenosis. Mild left facet effusion is noted.L4-L5 demonstrate progression of degenerative changes with resultant severe central sinal stenosis and bilateral moderate foraminal since prior exam.L5-S1 demonstrate mild interval progression of degenerative changes without spinal stenosis, however severe bilateral (L>R) neural foraminal stenosis.
1.Progression of degenerative changes at L3-L4 and L4-L5 levels with resultant sever central stenosis at both levels as detailed. 2.No spinal stenosis at other levels.3.Neural foraminal compromise at detailed per level above.
