Left-sided sciatica with weakness in dorsiflexion For the purpose of this dictation, the lowest visualized intervertebral disc space is labeled L5-S1. There is normal lumbar lordosis. The spine alignment is anatomic. 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 L1-L2 level. The paraspinal soft tissues are unremarkable.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: no neuroforaminal narrowing or spinal stenosis. L3-L4: Diffuse bulging of disc which abuts thecal sac. No neuroforaminal narrowing or spinal stenosis. L4-L5: Diffuse bulging of disc with associated broad-based disc protrusion towards left side lateral recess which compress left-sided nerve root. Disc desiccation is seen.L5-S1: Diffuse bulging of disc. Disc desiccation is seen. No neuroforaminal narrowing or spinal stenosis.
Central to left disc herniation at the level of L4-5 as described above.Diffuse bulging of discs at the level of L3-4 and L5-S1.
