80-year-old female experiencing radicular pain and right foot drop Alignment is anatomic. There are no fractures or subluxations. The marrow signal is benign. The conus is normal in signal and morphology and terminates at an appropriate level. Other than simple renal cysts, the visualized intra-abdominal and paraspinal contents are unremarkable.Disc desiccation and disc height loss are present throughout. Previous Modic type I discogenic reactive endplate changes at L3/4 now appear as Modic type II. Multiple small Schmorl's nodes are noted, unchanged.T12/L1 demonstrates a small right paramedian disc protrusion without central canal stenosis, unchanged.L1/2 demonstrates an eccentric bulge to the right, without significant stenosis, unchanged.L2/3 demonstrates mild to moderate disk disease and moderate hypertrophic changes of posterior elements. No evidence of central spinal stenosis or significant neural foraminal compromise. These findings are unchanged.L3/4 demonstrates advanced degenerative disk disease with significant loss of disk height. Mild to moderate hypertrophy changes of ligamentum flavum and minimally of the facets are noted containing minimal bilateral facet effusions. There is mild to moderate central spinal stenosis, mild left neuroforaminal stenosis, and moderate right neural foraminal stenosis. These findings are unchanged. A previously demonstrated small synovial cyst projecting posterior to the articulating facet on the right is no longer evident.L4/5 demonstrates mild degenerative disk disease and moderate hypertrophic changes of facets and ligamentum flavum. There is resultant moderate central spinal stenosis. There is no significant neuroforaminal stenosis. These findings are unchanged.L5/S1 demonstrates mild to moderate disk disease and hypertrophic changes of posterior elements however without central spinal stenosis or neural foraminal compromise, unchanged.Stable fibrofatty infiltrative changes of filum terminalis.
1.L3/4: Moderate central spinal stenosis, mild left neuroforaminal stenosis, and moderate right neural foraminal stenosis, unchanged.2.L4/5: Moderate central spinal stenosis, unchanged.3.Stable fibrofatty infiltrative changes of filum terminalis.
