Back pain, occasional radiation down lower extremities Five lumbar type vertebral bodies are presumed to be present. Vertebral body heights are within normal limits. Alignment is within normal limits. Bone marrow signal is benign. The conus medullaris is normal in position.There is developmental narrowing of the lumbar spinal canal with termination of the thecal sac at the upper S1 level. Individual levels as below.L1-L2: No significant disc disease. No spinal canal or neural foraminal stenosis.L2-L3: No significant disc disease. No spinal canal or neural foraminal stenosis.L3-L4: No significant disc disease. No spinal canal or neural foraminal stenosis.L4-L5: No significant disc disease. No spinal canal or neural foraminal stenosis.L5-S1: No significant disc disease. There is prominence of the epidural fat with thecal sac termination at the upper S1 level. There is otherwise no spinal canal or neural foraminal stenosis.
1. There is mild developmental narrowing of the lumbar spinal canal. There is also prominence of the epidural fat at the L5-S1 level with thecal sac terminating just inferiorly. Epidural fat prominence is at least predominantly developmental, but would suggest correlation with possible clinical findings of spinal canal stenosis at the L5-S1 level related to epidural lipomatosis.2. Spinal canal is otherwise preserved. No significant disc disease at any level. No evidence of impingement of the nerve roots in the neural foramina at any level.
