Acute neck and back pain. Follow-up of syrinx. Cervical spine: Alignment is anatomic. Vertebral bodies are preserved in height. The spinous processes of C3-C5 are small/hypoplastic. Marrow signal is normal. Intervertebral disks show no significant herniation. There is no spinal canal or foraminal stenoses. The cervical spinal cord shows normal morphology and signal. The included posterior fossa structures/lower brain show no gross abnormality. There is no Chiari malformation or crowding at the level of foramen magnum. The craniocervical and cervicothoracic articulations are anatomic.Thoracic spine: Alignment is anatomic. The vertebral bodies are present in height. There is no suspicious marrow signal abnormality. There is mild disc height loss at T7-T8 without significant disc herniation. The spinal canal and the neural foramina are preserved.There is mild diffuse dilatation of the thoracic spinal central canal extending from the mid T5 level into the conus medullaris to mid T12 level. Compared to the previous examination, this has slightly improved. The canal at C5-C6 level now measures in the axial plane 2.5 mm x 2 mm compared to 3.5 mm x 3 mm previously. Also, previously the dilatation has started at T3 level while it now starts at T5 level. There is no other signal abnormality within the spinal cord. Lumbosacral spine: Alignment is anatomic. The vertebral bodies are preserved in height. Of note, L5 is partially sacralized. The spinal canal and the neural foramina are preserved. Intervertebral disks are normal. The tip of the conus medullaris as lower L1 level. The conus shows normal morphology and signal, accounting for mild dilatation of the central canal described above. The cauda equina roots are normally, symmetrically distributed in the thecal sac. Fatty signal within the filum terminale at L2-L3 has not changed and remains very thin and short segment.
1.Mild dilatation of the central canal of the thoracic cord has slightly improved since December 2014. There is no new signal abnormality in the spinal cord.2.Short segment of fatty filum terminale at L2-L3 level has not changed.
