Altered gait and weakness, although diffuse. The vertebral column alignment is within normal limits. The vertebral body and disc space heights are preserved. The vertebral bone marrow signal is unremarkable. A slight disc bulge and bilateral facet hypertrophy, as well as ligamentum flavum thickening at L4-5 result in minimal to mild neural foraminal stenosis and perhaps slight spinal canal stenosis. There is also minimal disc bulging and facet hypertrophy at L3-4, without significant spinal canal or neural foraminal stenosis. There is no significant spinal canal or neural foraminal stenosis at the other lumbar spine levels otherwise. The spinal cord displays normal signal and morphology. The paravertebral soft tissues are unremarkable.
