70-year-old woman with lower back pain. There is multilevel degenerative spondylosis. At L1-L2, there is mild facet joint arthropathy and a minimal disc bulge, but no spinal canal or neural foraminal stenosis. At L2-L3, there is mild facet joint arthropathy. There is moderate disc bulge with a superimposed left paracentral disc protrusion with impingement upon the descending nerve roots. At L3-L4, there is facet joint arthropathy with effusions and disc bulging associated with significant narrowing of the spinal canal and mild narrowing of the bilateral neural foramina. At L4-L5, there is facet joint arthropathy with effusions and several small posterior synovial cysts, as well as a mild disc bulge with mild narrowing of the spinal canal and bilateral neural foramina. At L5-S1, there is facet joint arthropathy and mild disc bulge without significant narrowing of the spinal canal. There are small perineural cysts in the bilateral neural foramina at T12-L1. The vertebral column alignment is within normal limits. The vertebral body heights are preserved. The vertebral bone marrow signal is unremarkable. The imaged portions of the spinal cord displays normal signal and morphology. The paraspinous soft tissues are unremarkable.
