Reason: OA, spinal stenosis Symptoms: back pain Thoracic spine:Thoracic kyphosis and dextroscoliosis of the lower thoracolumbar spine is grossly similar. Otherwise alignment is anatomic. Multilevel heterogeneous marrow signal likely reflects focal fat. Mildly increased endplate degenerative changes at T7-T8 with associated increased STIR signal. Foci of increased T2 signal in T9 may represent hemangiomas. Multilevel disc desiccation. Vertebral body heights are intact. No abnormal signal within the cord. Right neural foraminal disc protrusion at T7-T8 is unchanged. No significant neural foraminal stenosis at this level. No significant spinal or neuroforaminal stenosis at any level.Lumbar spine:Grade 1 anterolisthesis of L3 on L4, slightly worse in the prior exam. Focus of low signal in the L1 and L3 vertebral bodies are unchanged. Otherwise, heterogeneous marrow signal appears similar to the exam. Mild endplate degenerative changes at L5-S1 slightly increased STIR signal. Multilevel disc desiccation with disc space loss, most severe at L4-L5 and L5-S1. Disc space loss at T12-L1 and L3-L4 may be minimally worse since the prior exam. No abnormal signal within the distal cord or conus, which ends at L1.T12-L1: Small left neural foraminal disc protrusion is slightly increased. Mild facet arthropathy. Mild left neural foraminal stenosis, unchanged. No spinal canal stenosis.L1-L2: No disc herniation.. Mild facet arthropathy No spinal canal or neural foraminal stenosis.L2-L3: Diffuse disc bulge with small central protrusion, unchanged. Mild facet arthropathy and ligamentum flavum thickening. Minimal spinal canal narrowing is unchanged. No neural foraminal stenosis.L3-L4: Large right paracentral disc extrusion extending 1.6 cm superiorly is new from the prior exam and narrows the right lateral recess. Mild facet arthropathy. Mild left neural foraminal stenosis is unchanged.L4-L5: No disc herniation. Mild facet arthropathy. Minimal bilateral neural foraminal narrowing is unchanged. No spinal canal stenosis.L5-S1: No disc herniation. No spinal canal or neural foraminal stenosis.Mild fatty atrophy of the paraspinous muscles. Left kidney is atrophic with small cysts. Subtle deformity of the aorta at L3 may represent ectasia is unchanged since the prior exam
1.New right paracentral disc extrusion at L3-L4.2.Multilevel degenerative changes in the thoracic spine, minimally increased.
