 Vertebral body heights in the cervical spine are normal. There is mild anterolisthesis of C2 on C3, C3 on C4, and C4 on C5 and mild retrolisthesis of C4 on C5 and C5 on C6. No high-grade spinal canal stenosis or frank cord compression is identified. Bone marrow signal is benign. Degenerative changes are seen throughout with loss of disc height, worst at C4-C5 and C5-C6. There is facet arthropathy throughout the cervical spine, worst at the left C5-C6 level.Individual levels as below:C2-3: Minimal disc bulge and ligamentum flavum thickening. No significant compromise to the spinal canal or right neural foramen. There is mild to moderate left neural foraminal stenosis.C3-4: Small disc osteophyte complex. There is mild right and moderate left neural foraminal stenosis. No significant spinal canal stenosis. C4-5: Small disc osteophyte complex with effacement of the ventral thecal sac. Dorsal thecal sac is patent. There is moderate to severe left neural foraminal stenosis and minimal right foraminal narrowing. C5-6: Small disc osteophyte complex, and ligamentum flavum thickening. There is mild spinal canal stenosis with effacement of the ventral and dorsal thecal sac. No evidence of frank cord compression or cord signal abnormality. There is moderate to severe left neural foraminal stenosis and mild right neural foraminal narrowing.C6-7: No significant compromise to the spinal canal or neural foramina.C7-T1: No significant compromise to the spinal canal or neural foramina.THORACIC SPINE
1. Degenerative changes in the cervical spine with mild spinal canal stenosis at the C5-C6 level. No evidence of cord compression or cord signal abnormality. Moderate to severe neural foraminal stenosis on the left at multiple levels in the cervical spine as detailed above.2. No significant spinal canal stenosis in the thoracic spine. There is minimal dorsal scalloping involving the upper thoracic cord raising the possibility of an arachnoid cyst posteriorly, but is of doubtful clinical significance given absence of significant cord flattening or signal abnormality.3. Advanced degenerative changes in the lumbar spine with scoliosis as seen on prior radiographs. There is moderate L2-L3 spinal canal stenosis and to a lesser degree mild to moderate L3-L4 spinal canal stenosis. There is moderate right L3-L4 and severe right L4-L5 neural foraminal stenosis.4. Please note transitional lumbosacral junction with 4 lumbar type vertebral bodies and sacralized transitional segment labeled L5 for the purposes of numbering.
