3-year-old with history of tethered cord repair and syrinx. Follow-up exam. There are postoperative findings related to prior tethered cord release. The conus medullaris terminates at the L1-2 level. There is unchanged curvilinear structure in the region of the filum terminale with T1 hyperintense components, which may be related to surgery. There is slight ventral translation of the conus medullaris and cauda equina nerve roots on the prone versus supine images. There is unchanged caliber of the syringomyelia that extends from the cervical spine cranial to the highest image level and extends to the conus medullaris. The vertebral body and intravertebral disc heights are maintained. The vertebral column alignment is anatomic. There is no significant neural foraminal or spinal canal stenosis. The vertebral bone signal is unremarkable.
