69-year-old female with lower back pain and right lower extremity pain. Evaluate for lumbar spine pathology. For the purposes of numbering, there are 5 lumbar-type vertebral bodies. There is grade 1 anterolisthesis of L5-S1 but the alignment is otherwise maintained. The vertebral body and disc space heights are preserved. The vertebral bone marrow signal is unremarkable. The spinal cord displays normal signal and morphology. The paravertebral soft tissues are unremarkable. Degenerative changes are as described below:T12-L1: There is no significant compromise to spinal canal or neural foramina.L1-L2: There is minimal disc bulge and mild facet arthropathy but no significant compromise to spinal canal or neural foramina.L2-L3: There is minimal disc bulge and mild facet arthropathy but no significant compromise to spinal canal or neural foramina.L3-L4: There is minimal disc bulge and mild facet arthropathy but no significant compromise to spinal canal or neural foramina.L4-5: There is minimal disc bulge eccentric to the right and facet arthropathy but no significant compromise to spinal canal or neural foramina.L5-S1: There is advanced facet arthropathy and disc uncovering as well as a mild disc bulge. There is mild effacement of the right lateral recess. There is mild to moderate right and mild left neural foraminal stenosis. There may be impingement on the right L5 nerve root. There is no central spinal canal stenosis.
Mild degenerative changes of the lumbar spine particularly at the L5-S1 level where there is advanced facet arthropathy, grade 1 anterolisthesis, and mild to moderate right neural foraminal stenosis with possible impingement of the exiting right L5 nerve root.
