 CERVICAL: There is mild motion artifact degrading image quality. There has been progressive interval volume loss and myomalacia centered at C5-6 through C6-7 levels measuring up to 21 x 4 mm on series 501 image 8, previously 12 x 4 mm. The cord at this level is flattened and is eccentric to the right with focal adhesion suspected along the right lateral aspect of the thecal sac (series 601 image 26).There is minimal subtle flattening of the ventral pons is compared to the prior examination, as well as mild prominence of the CSF space around the cervical cord which are suspected to represent interval mild diffuse/uniform volume loss as a result of progressive myelomalacia described above. There is prominent CSF pulsation artifact secondary to prominent CSF space around the cervical cord.There is straightening. The osseous marrow signal is within normal limits. There is interval loss of T2 disk signal and C6-7. The intravertebral disk heights and signal are otherwise within normal limits.There is no significant disk/endplate degenerative change or spinal stenosis in the cervical spine.The right V2 vertebral artery flow void remains indistinct, similar to prior examination. The remaining imaged flow-voids in the neck are preserved.THORACIC: There is mild thoracic levoscoliosis centered in the upper thoracic spine. There are the usual complement of 12 thoracic and 5 lumbar vertebral bodies. The osseous marrow signal is within normal limits. The thoracic thecal sac to cord caliber appears somewhat increased with prominent CSF space around the thoracic cord; this can be due to congenitally/developmentally larger thecal sac or due to mild uniform volume loss of the thoracic cord. However, given the focal myelomalacia in the cervical spine, this appearance is suspected to represent mild uniform volume loss as opposed to a developmental/congenital finding. Cord signal is within normal limits. There is no significant disk herniation or spinal stenosis the thoracic spine.LUMBAR: There is usual complement of 5 lumbar vertebral bodies with the last well formed disk space referred to as L5-S1. The osseous marrow signal is within normal limits. The conus terminates at L1-2, and has a normal signal characteristics and caliber. The conus is mobile and settles anteriorly in the spinal canal upon prone positioning. There is no fatty filum or lipoma. There is no dysraphism.L1-2: Minimal disk bulge with no significant spinal stenosis.L2-3: Minimal disk bulge with no significant spinal stenosis.L3-4: Minimal disk bulge with no spinal stenosis.L4-5: Minimal disk bulge. No significant spinal stenosis.L5-S1: Minimal disk bulge with no spinal stenosis.
1.Mild progressive myelomalacia centered at C5-6 through C6-7 as described above. There is subtle/mild uniform volume loss also suspected in the pons, cervical and thoracic cord as a result of progressive myelomalacia mentioned above.2.No new or separate areas of cord signal abnormality, syrinx or evidence of cord tethering.3.Mild thoracic levoscoliosis.
