Posttraumatic neck pain with left upper extremity radiation. Sagittal alignment is notable for straightening in addition to 2 mm of posterior subluxation of C4 relative to C5. The vertebral bodies are preserved in height. There is mild degenerative marrow signal subjacent to the endplates at C5-C6 and C6-C7. T1/T2-hyperintense lesions in the right aspect of C7 and C4 vertebral bodies probably represent hemangiomata. There is disc desiccation at all levels and mild height loss, most pronounced at C6-C7. There is mild ligamenta flava thickening extending from C4-C5 level through C6-7 level contributing to the below-described canal narrowing. There are anterior disc-osteophytes at C4-C5 through C6-C7 levels. The spinal cord shows normal signal and is only mildly deformed on the left side by the C6-C7 disc-osteophyte complex. Included posterior fossa structures are unremarkable. The paraspinal soft tissues are unremarkable and major cervical vascular flow voids are preserved. There is trace mucosal thickening in the right maxillary sinus.Level-specific findings: C2-C3: There is very minimal uncovertebral and left facet arthropathy but no significant spinal canal or neural foraminal stenosis.C3-C4: Disc-osteophyte complex flattens the ventral thecal sac resulting in mild spinal canal stenosis. Left facet and uncovertebral arthropathy resulting in moderate left neural foraminal stenosis.C4-C5: The retrolisthesis and disc-osteophyte complex result in mild-to-moderate spinal canal stenosis. Uncovertebral and facet arthropathy are more pronounced on the left side and result in severe left and moderate-to-severe right right neural foraminal stenoses.C5-C6: Small, central disc-osteophyte complex indents the thecal sac but causes no significant spinal canal stenosis. There is also mild facet arthropathy but no significant neural foraminal stenosis.C6-C7: The disc-osteophyte complex is associated with a left paracentral component which mildly deforms the spinal cord. Also, uncovertebral and facet arthropathy are associated with severe left and moderate right neural foraminal stenoses.C7-T1: There is no significant spinal canal or neural foraminal stenosis.
1.Multilevel degenerative cervical spondylosis is most pronounced at C6-C7 resulting in moderate spinal canal stenosis and severe left and moderate right neural foraminal stenoses. 2.At C4-C5, there is also severe left and moderate-to-severe right foraminal stenoses.
