64-year-old female with left lumbar radicular pain, left leg pain, and low back pain; history L4/5 disc herniation The signal intensity in the alignment the vertebral column remains unremarkable. Moderate degenerative disk disease at L4/5 and L5/S1 levels are again noted. The conus terminates at an appropriate level and is normal in signal as well as morphology. The visualized paraspinal contents are unremarkable.T12/L1 through L3/4: Redemonstrated are minimal to mild degenerative changes and no central spinal stenosis or neural foramina compromise. L4/L5: There is a new left paracentral disc protrusion which effaces the left lateral recess and causes a moderate degree of central stenosis. Previously demonstrated mild degenerative disk disease and hypertrophic changes of posterior elements are again noted without significant neural foramina compromise.L5/S1: Redemonstrated is degenerative disk disease with disk bulge and loss of disk height and signal intensity.There is no central spinal stenosis or neural foramina compromise. A previously suspected small herniated disk in the left paramedian location not evident on the current exam.
L4/L5: There is a new left paracentral disc protrusion which effaces the left lateral recess and causes a moderate degree of central stenosis.
