 Redemonstrated are postoperative findings of the lumbosacral spine for tethered cord repair. There is unchanged appearance of fat signal intensity involving the tip of the conus extending from the L4-L5 level down to the lower S1 level and remains adherent to the dorsal dural margin. The spinal cord displays normal signal and appears to slightly shift anteriorly on prone imaging with respect to supine imaging. The tip of the conus remains approximately at the mid L4 level. There is apparent clumping and a peripheral distribution of the cauda equina nerve roots. The vertebral column alignment is within normal limits. The vertebral body and disc space heights are preserved. The vertebral bone marrow signal is unremarkable. There is no significant spinal canal stenosis. The paravertebral soft tissues are unremarkable, aside from the surgical alterations.
Postoperative findings in the lumbosacral spine with redemonstration of an intradural lipoma and low-lying conus medullaris. Apparent clumping of the cauda equina nerve roots may indicate arachnoiditis.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
