 There is no evidence of acute cord compression. As noted on the prior examination, while counting from above, there are 6 lumbar vertebral bodies.There is redemonstration of extensive abnormal T2 hyperintensity within the cord extending from T6-7 down to T12 level, slightly progressed superiorly from T8-9 level on the prior exam. There's no significant cord expansion.There is a stable small rounded nodular focus along the dorsal aspect of the thecal sac measuring 6 mm on series 1001 image 12 at the recent laminectomy level.Postsurgical hardware can be better visualized with CT if clinically indicated. There has been evolution of immediate postoperative findings related to T11 laminectomy, and posterior surgical fusion of L3 and L4 with bilateral pedicle screws and interbody spacer as well as anterior fusion of L6 through S2 with probable S1 corpectomy (as numbered previously). There are laminectomy defects at L4 and L5. Old screw tracts are present through L5 and L6. There are interbody spacers at L4-5 and L5-6. There is no significant osseous marrow edema.
1.This is a limited exam specific for the exclusion of acute cord compression only. No acute cord compression is identified.2.Due to the screening nature of this protocol details are not as evident on imaging as dedicated protocols of the spine. However, there appears to be mildly severe extension of abnormal T2 hyperintense signal within the cord extending from T6-7 down to T12 on exam, previously extending from T8-9 level to T12. There is no expansion of the cord.3.Interval evolution of immediate postsurgical changes on the prior examination.4.No epidural collection is appreciated.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
