Known Chiari and syrinx. Evaluate for change in syrinx. Also evaluate for cord tethering. There is an upper cervical syrinx associated with Chiari 1 malformation. Please refer to the report of the recent brain and cervical spine MRI from February 27, 2016, for more details.The thoracic vertebral column alignment is anatomic in the sagittal plane on the right degenerative. The vertebral body and disc space heights are preserved. The vertebral bone marrow signal is unremarkable. There is no significant spinal canal stenosis. There is minimal focal (6 mm long) dilatation of the thoracic cord central canal at T9 level, measuring 1 mm x 3 mm axially. Otherwise, the thoracic central canal is prominent between T6-T9 levels. Otherwise, the spinal cord displays normal signal and morphology. The conus medullaris is normal appearing. The tip of the conus medullaris lies at the T12 level, which is normal. The paravertebral soft tissues are unremarkable.
1.Small thoracic syrinx at T9 level, as described above. Otherwise, the mid/lower thoracic central canal between T6 and T9 levels is prominent.2.Normal position of the conus medullaris.3.Chiari I malformation and upper cervical syrinx. Please refer to the report of the recent brain and cervical spine MRI from February 27, 2016 for more details.
