 For consistency, numbering is performed based on prior MRI with the lowest lumbar type vertebral body transitional and represent S1 (or L6).CervicalAgain seen are multiple segmentation anomalies within the cervical spine. Convex left curvature of the cervical spine is seen from the occipital atlantal articulation through C4 with convex right curvature from C5 through C7. Anterior tubercle of C1 appears to be fused with the dens. Left C1 facet and left C2 facet are fused. C3 vertebral body is a butterfly vertebral body with fusion with C2 in its right aspect. C4 is a left sided hemivertebral body. C5 through C7 demonstrates shortening of the left aspect of the vertebral body heights in comparison with the right on the coronal images. No signal abnormality in the cervical cord including syrinx or evidence of stenosis. CSF spaces at the craniocervical junction are also patent.Thoracic spine demonstrate a left T2 hemi-vertebral body. Dedicated thoracic spine study was not obtained, however on the coronal T2 sequence, there is evidence of prominent central canal/tiny syrinx which was present on prior study from 5/7/2013.LumbarConus tip terminates at L2/L3 (based on prior numbering) which is at the lower limits of normal with tip directed dorsally. Fatty filum terminale again noted. Interval tethered cord release has been performed. Prone sequence demonstrates some anterior motion of the conus. Vertebral body heights and alignment are maintained. No significant spinal canal or neural foramina stenosis. Conjoined right S1 and S2 nerve roots incidentally noted.
1. No signal abnormality in the cervical cord or extrinsic compression.2. Dedicated thoracic spine study was not performed. On the coronal T2 sequence including the thoracic spine, there is evidence of prominent central canal/tiny syrinx which was present on prior study from 5/7/2013. Finding is of uncertain clinical significance. May consider complete thoracic spine study if clinical symptoms are thought to be attributable to it for better comparison with prior.3. Multiple segmentation anomalies involving the cervical and upper thoracic spine as detailed above.4. Fatty filum terminale and conus at L2-3 again seen. There is some anterior motion of the conus on the prone sequence compatible with history of untethering.Central cord T2 prominence/syrinx starting at the level of C7 through the conus tip measuring up to 3 x 2 mm at the level of T7/T8. Borderline low-lying position of the conus tip with positioning of the tip dorsally possibly representing tethering particularly in light of the fat within the filum terminale. Prone imaging can be done for further evaluation. Right sided distal nerve root clumping. Multiple segmentation anomalies predominantly involving the cervical spine.
