Lumbosacral radiculitis with radiation down left leg. Re-assess lumbar degenerative disk disease. 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.At L5-S1 there is redemonstration of loss of disc space height, disc desiccation and a diffuse disc bulge associated with effacement of the fat at the left lateral recess and extension of disc material into the neural foramina bilaterally. There are associated endplate osteophytes as well. There is redemonstration of mild facet and ligamentum flavum hypertrophy at this level. Overall there is no significant interval change when compared to the previous exam.At L4-5 there is redemonstration of bilateral facet hypertrophy and ligamentum flavum hypertrophy which has mildly progressed since the prior exam. There is no significant compromise to spinal canal or exiting nerve roots at this level.At L3-4 there is no significant compromise to spinal canal or neural foramina. There is mild facet hypertrophy present at this level which has not changed substantially compared to the previous examAt L2-3 there is no significant compromise to spinal canal or neural foramina. There is mild ligamentum flavum hypertrophy at this level which has not changed substantially compared to the previous. There are new endplate reactive changes present at this level associated with a disc bulge and some mild narrowing of th neural foramina. The endplate reactive changes are heterogeneous signal on T2 and low signal on T1.At L1-2 there is no significant compromise to spinal canal or neural foramina.There is a new Schmorl's node present at T12-L1 associated with some adjacent marrow signal changes which are low signal on T1 and high signal on T2There is a left renal lesion which is bright on T2 and low signal on T1 which suspect was present on the prior exam but is only included on the very top image of this exam as well as a prior exam. Most likely this represents a renal cyst but is incompletely evaluated on this exam.
1.There is mild encroachment of the nerve roots at the left lateral recess at L5-S1 due to degenerative changes which is stable compared to the previous exam. 2.There is redemonstration of multilevel degenerative changes present in the lumbar spine which are not associated with compromise to spinal canal or exiting nerve roots. There is some progression of facet hypertrophy at L4-5 but otherwise no substantial change. There is also endplate reactive change at L2-3 as well as Schmorl's node at T12-L1 which has progressed since the prior exam and appears to be in a somewhat subacute stage.
