Sciatica [724.3], Reason for Study: ^Reason: history of spinal stenosis and nerve root compression. Progression? History: Lumbar pain For the purpose of this dictation, the lowest visualized intervertebral disc space is labeled L5-S1. There is normal lumbar lordosis. There is minimal anterolisthesis of L3 on L4, no change since prior scan.The vertebral body height is preserved. The bone marrow and end plates demonstrate a normal MR appearance. The signal of the visualized cord is normal. The epidural space, thecal sac, and spinal cord are preserved with no evidence of spinal canal/neural foraminal narrowing. The conus medullaris terminates at the T12-L1 level. The paraspinal soft tissues are unremarkable.There is no evidence of abnormal enhancement, cord compression or mass. Degenerative changes are specified by the intervertebral level as follows: T12-L1: no neuroforaminal narrowing or spinal stenosis. L1-L2: no neuroforaminal narrowing or spinal stenosis. L2-L3: There is broad based left side far lateral disc protrusion. No definitive imaging evidence of nerve root compression by the disc. No change since prior scan. L3-L4: Decreased disc height with dessication. Diffuse broad based disc bulging. Associated with bilateral ligamentum flavum thickening, there is moderate to severe spinal canal stenosis, no change since prior scan. L4-L5: Disc dessication was seen. There is broad based left side foraminal disc protrusion with extension toward far lateral aspect. Deformed thecal sac and left side nerve roots around the left side recess were seen. No significant interval change since prior scan. L5-S1: no neuroforaminal narrowing or spinal stenosis.
1. Multifocal (L2-L3, L3-L4 and L4-L5 intervertebral disc herniations) disc herniations and spinal canal stenosis of L34 were again demonstrated, no change since prior scan.2. No abnormal enhancement.
