Female, 58 years old, syrinx and tethered cord, six-month follow-up Extensive postoperative findings are again seen in the lumbar spine related to lipomyelomeningocele repair and cord detethering. Syringohydromyelia of the distal spinal cord spanning from approximately T12 to L2 is unchanged in caliber and extent. At its widest point it measures approximately 5 x 3 mm.The distal spinal cord remains closely apposed to the posterior aspect of the spinal canal where it splays and tapers, ultimately becoming indistinguishable from the posterior canal wall. No change in cord position is seen on prone imaging.The distal lumbar spinal canal is ectatic. Partial fusion of the posterior aspects of the L4 and L5 vertebral bodies is again seen.There is prominence of the thoracic kyphosis which can be better assessed with standing radiographs. Vertebral body heights are preserved. No marrow replacement or marrow edema is detected. Again seen are mild degenerative changes including a left paracentral disc extrusion at the T12-L1 level and to a milder degree at the T11-T12 level which are present previously.Again seen is marked fatty atrophy of the lower lumbar paraspinal musculature.
1.Stable small syrinx involving the distal spinal cord.2.No significant change in position of the distal cord which does not demonstrate ventral motion on the prone sequence and may represent re-tethering in the appropriate clinical setting.
