Reason: low back pain and bilateral lower extremity radicular sx, evaluate for spinal stenosis Five lumbar type vertebral bodies are presumed to be present which are appropriate in overall alignment and height. The conus medullaris on sagittal imaging is grossly intact. There is multilevel disk desiccation . There is epidural lipomatosis in the sacral spinal canal which is stable compared to prior exam.There is focal fatty replacement present in the sacral alae bilaterally.At L5-S1 there is a disk bulge present associated with bilateral facet hypertrophy. There is narrowing of the neural foramina bilaterally with some mild encroachment exiting nerve roots at this level . Compared to the previous exam is no significant interval change.At L4-5 there is no significant compromise to spinal canal or neural foramina. There is moderate bilateral facet hypertrophy present at this levelAt L3-4 there is no significant compromise to spinal canal or neural foramina. There is moderate facet and ligamentum flavum hypertrophy present at this levelAt L2-3 there is no significant compromise to spinal canal or neural foramina.At L1-2 there is no significant compromise to spinal canal or neural foramina.There is redemonstration of cystic lesions in the left kidney which are present on the prior exam and have not changed substantially. Most likely they represent cysts.
1.There are degenerative changes present in the lower lumbar spine mainly in the form of facet hypertrophy associated with encroachment of the exiting nerve roots at L5-S1. These findings are stable compared to the previous 2010 exam.
