Pain, history of transverse myelitis Anterior cervical fusion hardware is partially imaged. No obvious cervical spinal canal stenosis on the limited sequences covering the cervical spine.Thoracic:Cord signal abnormality involving the right upper thoracic cord on prior study from 12/2/2013 is no longer seen. No cord signal abnormality is appreciated on the current study. The thoracic spine is in normal alignment. The vertebral body heights are well-maintained. Minimal degenerative changes are seen with minimal disc bulges. There is no significant disk bulge, herniation, spinal canal or foraminal stenosis within the thoracic spine. No worrisome focal marrow signal abnormality is appreciated. Small scattered perineural cysts incidentally noted.Lumbar:Five lumbar type vertebral bodies are present. Vertebral body heights are within normal limits. Alignment is within normal limits. Bone marrow signal is benign. The conus medullaris is normal in position.Mild degenerative changes are seen, as described below:L1-L2: No significant disc disease. No spinal canal or neural foraminal stenosis.L2-L3: No significant disc disease. No spinal canal or neural foraminal stenosis.L3-L4: Disc desiccation with mild disc bulge without significant spinal canal stenosis. Mild right and minimal left neural foraminal narrowing. L4-L5: Disc desiccation with central and right foraminal disc protrusion which appears more prominent since prior MRI from 12/2/2013. There is contact of the right L4 nerve root in the right neural foramen. There is no significant spinal canal stenosis. There is mild to moderate right neural foraminal stenosis and minimal left neural foraminal narrowing. Mild facet arthropathy.L5-S1: No significant disc disease. No spinal canal or neural foraminal stenosis. Mild facet arthropathy.Paraspinous soft tissues are within normal limits.
1. Previously seen thoracic cord signal abnormality involving the right upper thoracic cord seen on prior study has resolved. No abnormal signal or spinal canal stenosis in the thoracic spine is appreciated.2. Mild degenerative changes in the lumbar spine. There is a central and right foraminal disc protrusion at the L4-L5 level which appears progressed since prior study from 12/2/2013 and contacts the exiting right L4 nerve root. There is no significant spinal canal stenosis at any level in the lumbar spine. Please see additional details above.
