History of low back pain. Evaluate for nerve impingement, vertebral compression. Examination is limited due to motion degradation. There is grade 1 anterolisthesis of L5 on S1. Vertebral body heights and disc heights are grossly maintained. There is nonspecific heterogeneous bone marrow signal. Conus medullaris is normal in appearance and terminates at the T12-L1 level. Fat at the L4-5 level is thought to be in the dorsal epidural space. Right renal cyst.T12-L1: There is no significant compromise to spinal canal or neural foramina.L1-L2: There is no significant compromise to spinal canal or neural foramina.L2-L3: There is no significant compromise to spinal canal or neural foramina.L3-L4: There is no significant compromise to spinal canal or neural foramina.L4-5: Advanced facet arthropathy with small amount of fluid in the joint. Small synovial cysts posterior to the facet joints. There is no significant compromise to spinal canal or neural foramina.L5-S1: Advanced facet arthropathy with small amount of fluid in the joint. Small synovial cysts posterior to the facet joints. Mild disc bulge. There is moderate to severe right and moderate left neural foraminal narrowing. There may be impingement of the exiting L5 nerve roots. There is no spinal canal stenosis.
1.Grade 1 anterolisthesis of L5 on S1 with advanced facet arthropathy at L4-5 and L5-S1.2.Moderate to severe right and moderate left neural foraminal narrowing at L5-S1, where there may be impingement of the exiting L5 nerve roots.
