Reason: eval lumbar stenosis History: LBP, radiating bilateral pain into buttocks Alignment is anatomic. No abnormal marrow signal. Vertebral body heights are maintained. Multilevel disc desiccation without significant disc space loss. No abnormal signal within the distal cord or conus which ends at L1-L2. Small terminal ventricle.T12-L1: No spinal or neuroforaminal stenosis.L1-L2: No spinal or neuroforaminal stenosis.L2-L3: Minimal diffuse disc bulge. No spinal or neuroforaminal stenosis.L3-L4: Mild diffuse disc bulge. Ligamentum flavum hypertrophy. Bilateral facet arthropathy and effusions. Mild narrowing of the central canal but no significant crowding of the cauda equina. No neuroforaminal stenosis. Overall similar to prior exam.L4-L5: Diffuse disc bulge. Ligamentum flavum hypertrophy, particularly on the left. Bilateral facet arthropathy and effusions. Mild effacement of the ventral thecal sac, however there is no significant canal stenosis. Mild right neuroforaminal stenosis. No left neuroforaminal stenosis. Overall similar to prior exam.L5-S1: Diffuse disc bulge. No spinal canal stenosis. No neural foraminal stenosis. Overall similar to prior exam.Small bilateral renal cysts.
Mild narrowing of the central canal at L3-L4 but no significant crowding of the cauda equina. Overall unchanged from prior exam.
