Rheumatoid and osteoarthritis with significant neck pain and stiffness. There is 5 mm of retrolisthesis of C5 upon C6 associated with disc space narrowing, disc-osteophyte formation, and endplate irregularities and bone marrow edema. There is associated mild spinal canal narrowing and moderate bilateral neural foraminal narrowing. There is also trace retrolisthesis of C6 on C7 with mild disc-osteophyte formation that results in mild spinal canal narrowing and moderate bilateral neural foraminal narrowing. There is straightening of the alignment of C2 through C5 in the sagittal plane without associated degenerative spondylosis at these levels. There is focal prominence of the left ligamentum flavum with T3. The dens appears to be intact and there is no evidence of pannus formation. The vertebral body heights are preserved. The spinal cord displays normal signal and morphology. The cervical vascular flow voids appear to be intact and the paravertebral soft tissues are unremarkable.
Degenerative spondylosis at C5-6 and C6-7 with associated mild retrolisthesis and spinal canal narrowing.
