case_images: Magnetic resonance imaging (MRI) of the cervical spine was performed which demonstrated a lesion with effects of significant erosion on the C5-C6 facet joint, listhesis with suspected instability, displacement of the spinal cord to the left, epidural extension, and foraminal enlargement [Figures 1 and 2].
