43 year old female with history of low back pain and spasms. There is mild straightening of the lumbar spine. Alignment is otherwise unremarkable. Vertebral body heights are maintained.There is continued progression of L4 superior endplate degenerative changes with enlargement of the known Schmorl's node. Additionally, there is evolution of endplate marrow signal now demonstrating fat characteristics at L4-5. The remaining bone marrow signal is unremarkable.The spinal cord, conus and cauda equina are unremarkable with the spinal cord terminating at the mid L1 level.T12-L1: No significant disk abnormality. No spinal canal stenosis or neural foraminal narrowing.L1-2: There is mild diffuse disk bulge with a left paracentral/subarticular disk extrusion causing mild effacement of the left lateral recess which deflects the adjacent nerve roots. There is mild neural foraminal narrowing. No significant spinal canal stenosis.L2-3: There is mild diffuse disk bulge with a tiny right paracentral protrusion. No significant spinal canal stenosis or neuroforaminal narrowing. There is a new tiny central annular fissure.L3-4: There is mild diffuse disk bulge with a superimposed protrusion which effaces the inferior aspect of the spinal canal. There is moderate narrowing of the right neuroforamina. The left neural foramen is unremarkable. No significant spinal canal stenosis.L4-5: There is moderate diffuse disk bulge with slight effacement of the ventral thecal sac. No significant spinal canal stenosis. Mild lateral foraminal narrowing.L5-S1: There is mild diffuse disk bulge, asymmetric on the left. No significant spinal canal stenosis. Mild left neuroforaminal narrowing with mild suspected impingement of the exiting L5 nerve root.
Mild progression of degenerative disease as above.
