Herniated nerve root as a complication of spinal tap

Case report

Restricted access

✓ A case is described in which a patient suffered severe radicular leg pain following myelography. At surgery, a nerve root was found to be herniated through the dural puncture site. The leg pain was relieved after the dura was opened and the nerve root repositioned. The possible mechanism of such an injury is discussed.
