Female, 62 years old, low back pain and bilateral lower extremity radiculopathy. Degenerative grade 1 anterolisthesis of L4 on L5 is redemonstrated. Spinal alignment is otherwise within normal limits. Vertebral body heights are maintained. A few focal areas of high T1 and T2 signal are present in the bone marrow, stable since prior exam, compatible with intraosseous hemangiomas and/or focal fat. There are degenerative endplate marrow signal changes, most prominent at L3-4.The visualized distal spinal cord and conus medullaris demonstrate normal signal intensity and morphology. There is multilevel disc desiccation signal with loss of intervertebral disc height which is mild in the lower thoracic spine and L5-S1, moderate at L2-3 and L4-5, and marked at L3-4. Additional level specific degenerative findings are as follows:T11-12: Mild disc bulge with superimposed left foraminal disc protrusion. Bilateral facet arthropathy. No significant spinal canal stenosis. Mild right and severe left neural foraminal narrowing. Findings have progressed.T12-L1: No significant disc bulge. Moderate right and mild left facet arthropathy. No significant spinal canal or neural foraminal stenosis.L1-2: No disc bulge or herniation. Mild bilateral, right greater than left, facet arthropathy. No significant spinal canal or neural foraminal stenosis.L2-3: Moderate disc bulge and bilateral facet arthropathy. Prominent dorsal epidural fat. Moderate effacement of the thecal sac. Mild bilateral, left greater than right, neural foraminal narrowing. Degenerative changes have progressed at this level.L3-4: Moderate disc bulge and bilateral facet arthropathy. Mild effacement of the thecal sac. Mild to moderate bilateral, left greater than right, neural foraminal narrowing. Degenerative changes have progressed at this level.L4-5: Anterolisthesis with uncovering of the intervertebral disc and marked bilateral facet arthropathy. Mild spinal canal stenosis. Mild to moderate right and mild left neural foraminal narrowing. Degenerative changes have slightly progressed at this levelL5-S1: Mild disc bulge with a superimposed right foraminal disc protrusion. Marked bilateral facet arthropathy. No significant spinal canal stenosis. Moderate right neural foraminal narrowing. Degenerative changes have slightly progressed at this level. A Tarlov cyst is seen along the right S2 nerve root.
Multilevel lower thoracic and mid to lower lumbar spondylosis, mildly progressed from the examination on 12/1/2005. I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
