74 years Female (DOB:8/28/1941)Reason: F/U MRI. H/O lumbar spinal stenosis s/p decompressive surgery in 2012. Please compare to MRI from 2014. History: low back pain, persistent bilateral lower extremity weaknessPROVIDER/ATTENDING NAME: HELENE G RUBEIZ HELENE G RUBEIZ Five lumbar type vertebral bodies are presumed to be present which are appropriate in overall height. The conus medullaris on sagittal imaging is grossly intact. The patient is status post L3-4 hemilaminectomy. There is a mottled appearance to the lumbar marrow.At L5-S1 there is no significant compromise to spinal canal or neural foramina. There is loss of disc space height, disc desiccation and diffuse disc bulge at this level. There is partial effacement of fat at the lateral recess at this level. This is stable compared to the prior exam.At L4-5 there is anterior subluxation of L4 on L5 by 7 mm. There is loss of disc space height this desiccation and diffuse disc bulge at this level associated with moderate bilateral facet hypertrophy and effacement of the fat at the lateral recess bilaterally. Overall there is a moderate degree of spinal stenosis at this level. Although the neural foraminal are narrowed, within the neural foramina the exiting nerve roots are surrounded by fat. This is stable compared to the prior examAt L3-4 there is no significant compromise to spinal canal or neural foramina. There is some loss of disc space height and disc desiccation as well as a disc bulge at this level associated with partial effacement of fat within the neural foramina. There is partial effacement of the fat at the lateral recess bilaterally at this level. Overall there is mild to moderate spinal stenosis at this level. There is a left far lateral disc protrusion present at this level This has been stable since prior exam. There are some endplate reactive changes present this level.At L2-3 there is no significant compromise to spinal canal or neural foramina. There is a disc bulge present at this level.At L1-2 there is no significant compromise to spinal canal or neural foramina. There is a disc bulge present at this level. Some minor endplate reactive changes at this level.
There are multilevel degenerative changes present in the lumbar spine which overall appears stable compared to the previous exam. The worst levels at L4-5 where there is some mild subluxation of L4 on L5 associated with a moderate degree of spinal stenosis.
