Surgical treatment of mixed cervical spondylosis with spontaneous cerebrospinal fluid leakage: A case report

Figure 1 Magnetic resonance imaging of the cervical spine before surgery. A: Orange arrow shows a strip of leaking cerebrospinal fluid posterior to the C1-4 vertebra; B: Protrusion of the C4/5 disc into the spinal canal, narrowing of the spinal canal at the level of the corresponding disc, loss of the epidural space, compression of the spinal cord, and a high signal area in the medulla.

Figure 2 C4/5 with "sickle-shaped" disc prolapse and calcification, reduced sagittal diameter of the cervical spinal canal, and loss of epidural fat.

Figure 3 Correct position of the cervical interbody fusion and restoration of intervertebral height. A: C-spine posterior anterior; B: C-spine left anterior oblique.

Figure 4 Postoperative magnetic resonance imaging. A: 1 wk after surgery; B: No significant compression of the spinal cord.
