MRI and CT. a MRI T2-weighted imaging. Sagittal imaging showed spinal cord anterior indentation at the level of C5–6 (arrow). T2 high signal change was not observed. b CT myelography sagittal reconstruction imaging showed that the anterior indentation of spinal cord is because of ossification of the longitudinal ligament (arrow). c MRI T2-weighted imaging and CT myelography axial imaging at the level of C5–6 showing right side C6 nerve root compression (nerve root sleeve disappearance, arrow head) in addition to the spinal cord compression
