Intracranial hypotension following scoliosis surgery: dural penetration of a thoracic pedicle screw.

ABSTRACT

The authors report on a 14 years old female with intracranial hypotension who had a history of spinal instrumentation surgery for scoliosis 3 months prior to her admission. She had been diagnosed with migraine in a neurology clinic and was under medical therapy when presented. During the investigation process, a right thoracic pedicle screw, which was penetrating and transversing the dura mater at the T3-T4 level was identified. The diagnosis and management of such a case is discussed. Knowledge of this entity is of extreme importance to spine surgeons, in order to prevent delayed diagnosis and possible complications.
