20-year-old male with history of syrinx and tethered spinal cord, now experiencing new worsening back pain Cervical spine:Alignment is anatomic. There are no fractures or subluxations. The marrow signal is benign. The cervical and upper thoracic cord are normal in signal. The cervicomedullary junction is normal. The cerebellar tonsils are in normal position. The visualized paraspinal contents are unremarkable. There are no degenerative changes, disc herniations, or stenoses.Lumbar spine:Redemonstrated is a low-lying conus near the lumbosacral junction with postoperative changes related to prior cord untetherings. The distal thecal sac is ectatic and demonstrates septations. As before, the distal spinal cord abuts and may be adherent to the posterior thecal sac. Cauda equina nerve roots are also peripherally located as seen before which may also be reflective of adhesion. Prone images demonstrate no appreciable ventral motion of the distal cord. As before, a syrinx is present extending from the L1 to the L3-L4 levels and measuring up to 2 x 4 mm in the axial plane. These findings are unchanged.Alignment is anatomic. Vertebral body heights and intervertebral disc spaces are unchanged in morphology. The bone marrow demonstrates normal signal. No spinal canal or neural foraminal stenosis is present.
1.Negative noncontrast cervical spine MRI.2.No significant change in the appearance of lumbar spine including a small distal cord syrinx.
