 CERVICAL: There is moderate motion artifact limiting evaluation, despite of acquiring multiple repeat sequences. There are unchanged postoperative findings related to Chiari decompression. The alignment and vertebral body heights are grossly preserved. The disk heights and signal are grossly unremarkable. There is no definite cord signal abnormality or syrinx. Evaluation of the flow-voids in the neck is limited due to motion artifact. There is a stable posterior fossa arachnoid cyst partly imaged as compared to 7/15/2014 causing stable mass-effect on the left cerebellar hemisphere posteriorly. There is no significant spinal canal or neural foraminal stenosis is seen, although evaluation is limited.LUMBAR: The last well formed disk space is referred to as L5-S1. There is normal alignment of the lumbar spine. There is desiccation of L2-3, and L4-5 disks with loss of disk height. Vertebral body heights are preserved. The osseous marrow signal is within normal limits. The conus terminates at L1-2.T12-L1: No disk herniation or spinal stenosis.L1-2: Minimal disk bulge with no spinal stenosis.L2-3: Moderate central/left paracentral disk protrusion and disk bulge, bilateral facet arthropathy causing moderate spinal canal stenosis with encroachment upon the left greater than right subarticular recesses. No significant foraminal stenosis.L3-4: Diffuse disk bulge with tiny central disk protrusion, and bilateral facet arthropathy causing no significant spinal canal stenosis or neural foraminal stenosis.L4-5: Diffuse disk bulge, annular fissure with small central disk protrusion and facet arthropathy causing mild bilateral neural foraminal stenosis. No significant spinal canal stenosis.L5-S1: Diffuse disk bulge with no spinal stenosis.
1.Moderate central/left paracentral disk protrusion at L2-3 superimposed on disk bulge and bilateral facet arthropathy causing moderate spinal canal stenosis with encroachment upon the bilateral subarticular recesses (greater on the left). 2.Mild bilateral neural foraminal stenosis at L4-5.3.Motion limited cervical spine with no significant interval change.
