Figure 1

  1. Drawing of a CSF leak caused by a disk spur tearing the dura mater.

  2. Dynamic CT myelography showing contrast medium egress from the subarachnoid space into the epidural space at the level of the T3/4 intervertebral disc (open arrow). In this case, the contrast medium flows in a cranial direction in the epidural space beyond the site of the leak (arrows).

  3. Drawing of the surgical field: after the dura mater has been opened, the vertical tear in the ventral dura mater and the penetrating disk spur can be seen.

  4. Intraoperative image showing the tear and the disk spur, about the size of a kernel of rice.
