Reason: R/O Worsening of DZ History: Known DJD of L spine, acute chronic back pain 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. No abnormal enhancing lesions are identified in the lumbar spine.At L5-S1 there is disk dessication and a broad based central disk extrusion which is associated with partial effacement of the fat at the lateral recesses - left more than right. Disk material extrudes behind the superior endplate of S1. There is mild encroachment of the nerve roots at the left lateral recess. Compared to the prior CT lumbar spine this has not changed significantly.At L4-5 there is no significant compromise to spinal canal or neural foramina. There is minor disk bulge at this level.At L3-4 there is no significant compromise to spinal canal or neural foramina.At 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.
1.There are degenerative disk changes present at L5-S1 with broad-based disk protrusion resulting in mild encroachment of the nerve roots at the lateral recesses- left more than right. Compared to the prior CT lumbar spine this has not changed significantly.
