Reason: lumbar anterolisthesis at L4-L5 History: back and buttock 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. There is multilevel disk desiccation present.At L5-S1 there is no significant compromise to spinal canal or neural foramina. There is moderate degree of bilateral facet hypertrophy at this level.At L4-5 there is no significant compromise to spinal canal or neural foramina. There is a marked degree of facet hypertrophy at this level associated with ligamentum flavum hypertrophy, loss of disk space height and disk desiccation. There is mild (2mm) anterior subluxation of L4 on L5 present. Overall there is a mild degree of spinal stenosis present at this level.At L3-4 there is no significant compromise to spinal canal or neural foramina. There is a mild to moderate degree of bilateral facet and ligamentum flavum hypertrophy present at this level associated with a disk bulge. Overall there is a mild degree of spinal stenosis at this levelAt L2-3 there is no significant compromise to spinal canal or neural foramina. There is a mild disk bulge at this level and mild ligamentum flavum hypertrophy at this level.At L1-2 there is no significant compromise to spinal canal or neural foramina. There is loss of disk space height, disk desiccation and endplate reactive changes associated with a disk bulge at this level.
1.There are degenerative changes present in the lumbar spine worse at L4-5 and L3-4 without a significant compromise to the spinal canal or neural foramina. There is mild degree of spinal stenosis present at L3-4 and to L4-5.
