Female, 59 years old, with spina bifida and syrinx, six month follow-up. Surgical changes are redemonstrated in the lower lumbar spine compatible with prior repair of a lipomyelomeningocele and cord de-tethering. Syringohydromyelia of the distal spinal cord is redemonstrated showing no significant interval change. The syrinx begins at T12 and continues down to the L2 level with a maximal caliber of approximately 5 x 3 mm. The distal spinal cord remains atrophic.The distal spinal cord remains closely opposed to the dorsal thecal sac. The neural elements become indistinguishable in the lower spinal canal in an area of posterior element deficiency which is filled by prominent fatty material. The distal thecal sac is ectatic and septated. On prone imaging, no definite shift in position is seen in the distal spinal cord or cauda equina.The thoracic kyphosis and lumbar lordosis are both exaggerated similar to prior. Alignment is otherwise unremarkable. Fusion of the posterior aspects of the L4 and L5 vertebral bodies is unchanged. The spinal canal is not significantly compromised at any level. Minimal degenerative findings including small disc protrusions at T10-11 and T12-L1 are unchanged.
1.Redemonstrated are postoperative findings compatible with lipomyelomeningocele repair and cord untethering.2.Stable distal spinal cord syringohydromyelia.3.Findings suggestive of tethered cord are unchanged.4.Mild degenerative findings are unchanged.
