Female, 30 years old, status post spinal cord injury at T7 with back pain. Bilateral posterior instrumented fusion is seen with stabilization rods affixed to bilateral pedicle screws at T4, T5, T6, T9 and T10.There is an exaggeration of the normal thoracic kyphosis. The T7 and T8 vertebral bodies are fused with obliteration of the intervening disc space. Elsewhere vertebral body morphology is relatively normal and there is no evidence of any concerning marrow replacement or marrow edema. No pathologic enhancement is seen.Beginning in the cervical region, severe septated syringohydromyelia is seen continuing inferiorly to the T9 level. The spinal cord parenchyma through this region is maximally thinned and the syrinx cavity fills the entire spinal canal. Below T9, the spinal cord demonstrates a normal appearance.Minimal degenerative disc disease is seen at T2-3 and T3-4. No significant spinal canal stenosis is seen. The T7-8 neural foramina are narrowed due to vertebral body fusion at this level. Otherwise, the neural foramina are within normal limits.
1.Evidence of instrumented posterior spinal fusion from T4 through T10.2.Fusion of the T7-8 vertebral bodies may reflect prior trauma or a congenital anomaly.3.Severe septated syringohydromyelia affects the spinal cord from the cervical region down to the T9 level. Below T9, the spinal cord shows a relatively normal morphology.
