Other specified congenital malformations of spinal cord [Q06.8], Reason for Study: ^Reason: eval for pseudomeningocele History: headache For the purpose of this dictation, the lowest visualized intervertebral disc space is labeled L5-S1. Post-untethering operation follow up.Again, the distal spinal cord appears to be adherent to the posterior thecal sac and does not show evidence of identifiable movement on prone images comparing to supine images.The maximum AP diameter of the lower thecal sac ectasia appears to be smaller than prior images (prior 46mm, now 38mm). Multiple internal septation of the lower thecal sac are again seen, unchanged.Syrinx cavity seen from L1 to L5 is again seen and is stable in size and extent since prior scan.The spine alignment is anatomic. The vertebral body height is preserved. The bone marrow and end plates demonstrate a normal MR appearance. The signal of the visualized cord is normal. The epidural space, thecal sac, and spinal cord are preserved with no evidence of spinal canal/neural foraminal narrowing. The intervertebral discs demonstrate normal T2 intensity and height with no evidence of disc herniation. The paraspinal soft tissues are unremarkable.
1. Post cord untethering status follow up. There is no evidence of cord motion on prone position images. The spinal cord appears to be adherent to the posterior thecal sac, unchanged.2. Unchanged spinal cord syrinx extent and size of syrinx cavity.3. Decreased maximum diameter of dural ectasia at the level of L5 and below since prior scan (from 46mm to 38mm).
