Yearly follow-up, tethered cord. Examination is slightly motion degraded. Five lumbar type vertebral bodies are presumed to be present which are appropriate in overall alignment and height. The patient is status post laminectomies from L2 through L5 and partial at L1.The conus medullaris has its inferior tip at the L3 vertebral body level in stable position compared to the prior exam and directed posteriorly. There is redemonstration of a tiny syrinx in the distal spinal cord which is unchanged when compared to the prior exam. It measures 2 mm in diameter. Conjoined left L5 and S1 nerve roots incidentally noted.There is a no change in the position of the conus medullaris when placing the patient in the prone position.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. No spinal canal or neural foraminal stenosis.
1.Postsurgical changes of spinal cord untethering with unchanged appearance of the conus and cauda equina nerve roots. No anterior motion is appreciable in the prone sequence, which in the appropriate clinical setting may suggest retethering. Finding remains unchanged.2.Prominent central canal/tiny syrinx in the distal cord again seen. No new or enlarging syrinx.
