Patient Data

Age: 50 years
Gender: Male

Canal stenosis worse at C3/4 due to posterior osteophyte disc complex. Associated spinal cord edema at C3/4 extending inferiorly two segments.


Anterolisthesis of C4 with respect to C5 on flexion secondary to degenerative facet joints. This likely contributes to canal stenosis at C4/5

Case Discussion

On MRI imaging alone it is difficult to appreciate the facet joint instability at C4/5. This case demonstrates the value of functional imaging.
